Abstract

Cocoa is known as shade-loving plants, i.e. plants that suitably grow with shaded conditions. Therefore, particular cultivation techniques are needed, such as planting shade trees to cover cocoa trees from direct sunlight exposure. The utilization of shade-loving plants from annual and seasonal crops, such as coconut and corn, can provide several benefits for farmers, including optimal early growth of cocoa seedlings, and the byproduct of shade-loving plants can provide short-term economic benefits for farmers. Corn plants in sustainable cocoa farm management are grouped as pioneer plants that can provide temporary shade so that cocoa plants can be protected from direct sunlight because cocoa is known as a shade-loving plant. One of the efforts to get short-term income for farmers is to utilize corn as an intercrop while allowing for the generative phase of cocoa plants. This research aimed to find the growth and production of several corn varieties and their effect on cocoa growth under shade. It was conducted in a farmer^s field in Bualo Village, Paguyaman subdistrict, Boalemo District, Gorontalo Province from June to October 2022. This research employed a Randomized Group Design consisting of four treatments of corn varieties, namely: BISI 18 (V1), BISI 99 (V2), NASA 29 (V3)- and NK 6172, repeated 4 times with 16 experimental units. The results explained that all varieties of corn were able to adapt and tolerate conditions under coconut trees as shades, while the BISI 18 variety showed the highest production yield. Furthermore, there is a positive correlation between the use of corn as an intercrop with the vegetative growth of cocoa plants.

Abstract

The sago plant (Metroxylon sago Rottb.) is one of the native Indonesian plants that is able to produce starch in large quantities where most people in Indonesia consume sago as an alternative source of carbohydrates to replace the staple food. Low seed vigor at nursery is one of the factors causing low sago production. One of the efforts to increase the vigor of sago seedlings at the nursery stage is by providing invigoration treatment in the form of giving growth regulators. Therefore, it is necessary to conduct research on the effect of several growth regulators on the growth and development of sago seedlings. This research aims to determine the effect of atonic growth regulators and shallot extract on the growth and development of sago seedlings. This research was conducted in Pengkajoang Village, West Malangke District, North Luwu Regency, South Sulawesi Province. This research was arranged in a randomized block design experiment by immersing growth regulators (P) with various doses consisting of: control treatment (P0), shallot extract 500 ml/liter of water (P1), atonic growth regulators 500 ml/liter water (P2) and a combination of atonic growth regulators and shallot extract 1000 ml/liter of water (P3). The results showed that the appropriation of atonic growth regulators and shallot extract did not have a significant effect on the growth and development of sago seedlings. The conclusion of this research is that the appropriation of growth regulators and without growth regulators did not have an effect on the growth of sago seedlings. This shows that it is more efficient and more effective without the application of growth regulators.

Abstract

More than 90% of the need for garlic consumption in Indonesia are supported from import. Garlic is a plant that is able to optimally grow and develop in subtropical regions. One of the efforts to minimize the dependence on the import of garlic is through by microclimate manipulation in accordance to the subtropical conditions in the growth chamber. This study aims to examine the growth of the early vegetative phase in three different microclimatic conditions. It was conducted at IP2TP Margahayu, the Ministry of Agriculture in West Bandung Regency from October to November 2022. The experimental design used a Randomized Block Design with four repetitions. The treatments referred to three microclimatic conditions, i.e. (1) Smart Growth Chamber (SGC) in a tray with solar spectrum LED irradiation conditions with a constant intensity of 10.000 lux, exposure within 14 hours, and within 10 hours in the dark, controlled temperature of 22-25 C and controlled humidity of 60-70%, (2) open field in trays, and uncontrolled microclimate (control 1), and (3) open field in mulched plots- and uncontrolled microclimate (control 2). The plant growth parameters observed were the growth rate and plant height. Data analysis used the Analysis of Variance (ANOVA) followed by Tukey significant difference test using the PKBT-Stat program. The results of the study showed the initial success in manipulating microclimatic conditions through planting in SGC. The average growth speed of garlic in SGC (1.9 cm/day) was found faster than planting in trays in an open field (1.3 cm/day) and planting in mulched plots in open field (1.4 cm/day). Meanwhile, the height of SGC plant at one month after planting (44.2 cm) was higher than planting in trays in open field (28.1 cm) and planting in mulched plots in open field (29.8 cm). Further research will be carried out to study the development of garlic plants in SGC to the size of the tubers produced.

Abstract

Abstract. To determine the effectiveness and efficiency of the application of inorganic compound fertilizer NK (18-32) on sweet corn, an experiment was conducted at the experimental garden in Malang, East Java, Indonesia, starting from March to June 2020. The study was arranged in a single-factor RBD with ten treatments and three replications. The treatments were a combination of doses of NK compound fertilizer, a single fertilizer as a comparison, and a control (without fertilizer). Besides control, all treatments were given P fertilizer at a dose of 100 kg/ha. The result showed that doses of 500-750 kg/ha of NK compound fertilizer significantly increased the growth and yield of the sweet corn plant. Each 10 kg dose increase of NK fertilizer will increase the total dry weight of the plant by 1.3055 g and give a yield of 12.57-13.64 tons/ha of fresh cobs. This result is equivalent to the yield of standard N-K single fertilizer (350 kg/ha Urea + 75 kg/ha). The dose of NK compound fertilizer of 125-250 kg/ha was proven to be able to substitute 100% KCl fertilizer (75 kg/ha). The RAE value of 750 kg/ha of NK fertilizer was 105.99 % higher than the standard/comparative single fertilizer. The combination of 125 kg/ha NK fertilizer + 250 kg/ha Urea and 250 kg/ha NK fertilizer + 100 kg/ha Urea, respectively, resulted in a RAE 3.91% and 1.00% higher than the standard fertilizer.

Abstract
The need for organic fertilizers is getting higher along with public awareness of the important role of organic fertilizers in increasing crop productivity including rice which is a food commodity that is preferred by the Indonesian population. In addition, the availability of inorganic fertilizers is increasingly limited so other alternatives are needed to use organic fertilizers intensively. This study aims to determine the effect of the application and non-application of organic fertilizers in increasing the biomass of Inpari 37 rice. The type of organic fertilizer used is in solid form (powder) with a land area of 20 acres which is located in the Experimental Garden of the Agricultural Technology Research and Assessment Installation (IP2TP). The cropping pattern uses legowo 6:1. This research is quantitative by describing each observation of Inpari 37 rice biomass and comparing the application with 3 repetitions and non-organic fertilizer application consisting of 3 repetitions with random sampling. Observations were made once a week at 08.00 WITA starting from the vegetative period (one week after transplanting) to the generative period (one week after harvest). The data processing uses ANOVA whose results are displayed in the form of tables and diagrams. The results for the highest rice plant height were found in the non-application U3 with an average length of 115.6 cm, the highest number of rice leaves was found in the non-application U2 with an average of 173 leaves, the green color of the rice leaves was good in the application and non-application average - the average in each replicate is green, the longest root length for non-application is in U3, which is 41.55 cm, the highest number of panicles in non-application U3 is 32 panicles, and the highest number of grains for non-application U3 is 3872 grains. This shows that the application of organic fertilizers to rice is not directly utilized by the soil so the impact or results of the application of organic fertilizers take a long time when compared to non-organic or chemical fertilizers which are directly absorbed by the soil. Therefore, in the application of organic fertilizers, it is necessary to apply non-organic fertilizers at the right dosage so that the nutrients can be more easily used by the soil in increasing the biomass of rice plants.

Abstract

Indole-3-acetic acid (IAA) is widely associated with the plant growth-promoting rhizobacteria (PGPR) as the primary member of the auxins family produced by plants as it plays an essential role in the response of plant activities particularly in root initiation and development, shoot growth, etc. IAA cultivates in the enhancement of root length with an increase in the number of root branches, root hairs, and root laterals that aid in the uptake of nutrients from the surrounding. This study aims to decipher the response of root growth and development of tobacco inoculated by IAA hormones. Using PGPR as a primary association of bacterial group for IAA hormone, PGPR was colonized from the bamboo rhizosphere. PGPR was inoculated into the soil during seedling stages of tobacco with one to four times inoculation on 7, 14, 21, and 28 days after germination and measured the root observation until 35 days old of tobacco. The parameter observations include root length, root wet weight, root dry weight, root branches, and root hairs with three biological replicates. The form of Tukey^s test (one-way ANOVA) with SD was used as statistical analysis. The results shown IAA hormone successfully enhanced root length (30.62 cm), root wet weight (0.34 g), root dry weight (0.16 g), number of root branches (33), number of root hairs (726) after four times inoculation instead of one to three times and control treatment of IAA inoculation. To summarize this research, IAA associated with PGPR successfully enhances the root growth of tobacco after four times inoculation. Eventually, the IAA hormone plays an important role in response to root growth and development in tobacco.

Abstract

The greenhouse is a technology to overcome weather uncertainty as an impact of climate change. It can manage and control the temperature and humidity adjusted to the plant^s needs. Therefore, it requires accurate input of climate data from the monitoring system. The study aims to design an affordable and feasible monitoring system using three DHT22 sensors installed in a greenhouse. In particular, the data is appeared on LCD and is transmitted to the Ubidots platform using EPS32. The accuracy level is quantified by the difference values between DHT22 and the thermos-hygrometer, while the precision level is calculated using the correlation analysis of each sensor. As a result, the accuracy of DHT22 in measuring the temperature and humidity is high, with RMSE 1.48oC and 3.18%, respectively. Furthermore, the correlation values are 0.81 and 0.85. In conclusion, the research successfully produces an appropriate real-time system to monitor temperature and humidity.

Abstract

This article is the first of two-stage research in collaborative communication systems applying the IoT. The first stage is the concept of a cooperative communication system using MMSE (Minimum Mean Square Error) and the second stage is the application of a cooperative communication system among small-holder farmers in order to optimize the interactions among rural farmers.
The concept of first step is that the development of telecommunication technology which continues to increase in wireless media cannot be avoided. This system sometimes suffers from the effect of multipath fading which reduces the performance of the transmission system and results in low-quality of received data. The cooperative communication system is a virtual MIMO (Multiple Input and Multiple Output) system that implements multiple antennas on the transmitter and receiver sides and the addition of relays to work together to process signal transmission to reduce fading effects. In addition, the MIMO-OFDM signal detection process requires knowledge of channel conditions. The dynamics of this adaptive channel estimation principle are by adjusting the weighting based on the error value of the estimator output and the reference signal (actual signal). With the weighting value that is continuously updated, it is expected to be able to follow changes in the channel response. One of the channel estimation methods is the MMSE method which can take advantage of the spatial correlation of MIMO channels.
This research is based on research by Yazlin et.al (2013) on the performance of cooperative communication systems using the AF (amplifying and forward) technique with QPSK (Quadrature Phase Shift Keying) modulation. Based on this method, we try to continue research that builds a system for implementing the MMSE channel estimation technique for OFDM (Orthogonal Frequency Division Multiplexing) signals applied to a cooperative communication system using the DF (Decode and Forward) protocol (Stage 1).
Performance results were analyzed through simulation with Matlab software in terms of Bit Error Rate and Mean Square Error as a function of Signal Noise Ratio (SNR). The results expected to be used as a role model tool in terms of wireless communication using the MMSE OFDM channel estimator technique in cooperative communication systems and to be applied among small-holder farmers in the future (Stage 2).

Abstract

The Paddy plant is a rice-producing plant used as a staple food for the community. Based on data from the Central Statistics Agency in 2019, rice production in South Sulawesi is unstable. Estimating rice production will make it easier for the government and farmers to optimize planting planning and increase rice production. Remote sensing technology based on satellites and drones is one of the most widely used options for estimating rice production. Estimation of rice production uses vegetation indices such as NDVI (Normalized Vegetation Index), EVI (Enhancement Vegetation Index), GNDVI (Green Normalized Vegetation Index), and VARIGreen (Visible Athmosphericely Resistance Index). This study aims to determine the results and accuracy of estimating rice production using the drone and sentinel-2 imagery based on the vegetation indices when rice enters the maturation phase. In this study, the classification of the production level of paddy fields was carried out. A linear regression analysis was performed between the vegetation index values obtained from a drone and sentinel-2 images and rice production. The equation obtained from the regression analysis was used to estimate the production of rice plants in the paddy fields that were used as test samples. The results of this study, when the rice plant enters the maturation phase, the production estimation has a poor accuracy level. The guided classification that has been carried out has an Overall Accuracy value of 51,35%. The result of the estimation rice production at 73 DAP has an accuracy of 49,37% dan 31,43%.

Abstract

Maros Regency is one of the regencies that are food barns in South Sulawesi. Based on data released by BPS (Central Statistics Agency), in the last three years the production and productivity of agricultural land, especially rice plants in Maros Regency have experienced quite large fluctuations. Estimating the value of land productivity is very important to know as information material in support national food security. Geographic Information System is one of the modern technologies that can be used in estimating rice productivity, by utilizing Sentinel 2 image data. Spectral transformation to display aspects of plant conditions such as the vegetation index NDVI (Normalized Difference Vegetation Index), EVI (Enhanced Vegetation Index) and SAVI (Soil Adjusted Vegetation Index) can be used to predict agricultural land productivity. The purpose of this study was to determine the relation between the vegetation index value of the generative stage and the productivity of paddy fields in Alatengae village. The method used is a simple linear regression method in estimating the relation between rice productivity and the vegetation index NDVI, EVI and SAVI. From the analysis of the relation between the vegetation index and rice productivity, there is a very strong (positive) correlation, where the higher the value of the vegetation index, the higher the plant productivity will be. The result of processing the vegetation index between NDVI, EVI and SAVI in predicting rice productivity in the generative stage is the EVI vegetation index. The average deviation of the estimated productivity with field conditions is 0.36 Tons/ha or 5.02% for the NDVI vegetation index, 0.24 Tons/ha or 3.63% for the EVI vegetation index, 0.28 Tons/ha or 4.19% for the SAVI vegetation index.

Abstract

One of the factors that affect production yield of cultivation crops, especially rice, is pest/disease attacks. Various types of pests/diseases are often found in rice cultivation such as rats, stem borers and rice leaf folders. The damage caused by these pests can lead to production decreases and crop failure. To prevent an increase in pest infestation, monitoring can be carried out by employing technology such as Sentinel-2 satellite imagery. The identification of rice plant pests/diseases using Sentinel-2 satellite can be done using Vegetation Indices. NDVI and NDRE are Vegetation Indices that can be used for this purpose, because they are sensitive to plants chlorophyll values. The purpose of this study was to identify infected pest and disease of rice plants in paddy fields in Alatengae Village, Bantimurung District, Maros Regency by using Sentinel-2 satellite imagery. The methods of this study were spatial analysis and simple linear regression analysis, by looking at the relation between Vegetation Indices and rice productivity. The research results showed that based on the low value of NDVI and NDRE at the end of vegetative stage, some of rice fields were infected with pests and diseases. From field observation, it was found that the pests and diseases includedrats, rice leaf folders, borers and blasts. Pests/diseases infestation in paddy fields lead to a low Vegetation Index value which results in low rice production. Comparing the NDVI and NDRE, NDRE was better in detecting pests and diseases due to its sensitivity to the plants^ chlorophyll

Abstract

Maros Regency is one of the rice storage areas in South Sulawesi. According to the Central Bureau of Statistics for Maros Regency in 2020, the harvested area of rice decreased by 10.11% or 4,849.55 Ha compared to 2018 and rice production decreased by 16.96% or 37,719.68 tons. This causes the productivity of rice also decreased. One of the factors causing the decline in rice production in Maros Regency is drought. Sentinel 2 imagery is one of the remote sensing data that can be used to detect rice drought using the drought index method. This study aims to detect dryness of paddy rice in Allatengae Village using Sentinel-2A satellite imagery based on NDDI index analysis and determine the relationship between drought index and rice productivity. The method used is the Normalized Difference Drought Index (NDDI) method to determine the dryness level of paddy fields based on NDVI and NDWI parameters and the regression analysis method. From the results of this study, dry rice in Allatengae Village was detected in August and November. In September (42 HST), the average NDDI value was 0.0254 and it was in a mild class of drought conditions while in October (62 HST), the average NDDI value was 0.2425 and it was in a moderate class of drought conditions. and a correlation coefficient of -0.8636 was obtained, which means that there is a strong (negative) relationship between NDDI and rice productivity, where the higher the NDDI index value, the lower the rice productivity value.

Abstract

Subsistent/semi commercial farmers were very slow to adopt the new technology of maize cultivation, although the new introduction technology could be done by farmers, economies and compatible with farmer^s socio-culture. Generally, that was caused introduction technology need high inputs (i.e. superior seed maize varieties, fertilizer, and pesticides), and other sides orientation of maize cultivation by subsistent/semi commercial farmers for food security, farmers limited money to bought inputs, and inputs shop in sub district/village levels was nothing. The consequence was introduction of new technology could not extend and farmers back to existing technology after character building had finished. The research was conducted on 3 (three) farmer^s group and planted area 15 hectares of maize in South Timor Tengah district, East Nusa Tenggara province in 2017-2018. The research showed the problems could be overcome by guiding of new technology to farmers/farmer^s group among 1-2 times planting and building of new institutional i.e. clinic of technology on village level. Extension workers and group of farmer^s group (GAPOKTAN) manage clinic of technology. The clinic function was to inform new agricultural information to farmers/farmer^s group and be responsibility to supplying of inputs. To guarantee the continuity maize farming system, farmers need loan assistance with semi grand system. Farmers/farmers group borrow inputs from the clinic of technology and it refund by maize product after harvesting. The clinic of technology did maize processing and sold maize in early rainy season. The clinic of technology built maize seed industry unit in village level and bought inputs (fertilizer and pesticides) from agricultural shop on district/province level. This strategy could guarantee sustainability maize farming system and potential to develop in other village.

Abstract

Corn in Indonesia is grown by farmers with a narrow area of land and different marketing channels. The type of marketing channels chosen by farmers will have an impact on marketing margins and efficiency. Therefore this research was conducted with the aim of 1) analyzing the types of corn marketing channels in Sribatara Village and 2) analyzing marketing margins and corn marketing efficiency in Sribatara Village. The research method used is a survey method with the aim (sampling purpose) of interviewing traders directly. There are two marketing channels for corn, namely type I starts from farmers to village collectors and continues to wholesalers in Baubau city, while type II starts from farmers and continues directly to wholesalers in Baubau city. Collector traders perform the functions of buying, selling, transporting, and financing as well as market information functions. The results of the analysis of marketing margins, costs, and profits in type I and type II marketing channels each provide different benefits. Both marketing channels provide the same total margin of Rp. 3,000/Kg. The selling price at the farmer level is Rp. 4,000/Kg, while the selling price at the wholesaler level is Rp. 7,000/Kg. The difference between the two marketing channels is that there is a long marketing chain before the corn reaches the wholesalers in Baubau City. The results of the analysis of marketing efficiency for this type obtained a value of 57%, and marketing efficiency for type II marketing channels was 57%. This efficiency value indicates that the corn marketing system in Sribatara Village is efficient.

Abstract

Rice plants are included in agricultural commodities that have a high risk. Farming risks can be caused by agroecological environmental factors, input factors and management. This study aims to (1) determine the magnitude of the production risk of rice farming- (2) Identify production factors that affect rice production risks- This research was conducted in Lampulung Village, Pammana District, Wajo Regency. The population in this study amounted to 618 people. From this population, 5% of the population was taken so that a sample of 30 people was taken. Analysis of the coefficient of variation is used to determine the magnitude of the risk and the Just and Pope model is used to identify risk factors. The results showed that (1) the risk of rice production in Lampulung Village, Pammana District, Wajo Regency was relatively large with a coefficient of variation of 0.524, meaning that for every ton of rice productivity that is expected, there is a productivity risk faced by a risk of 52.4 percent of total production which are expected- (2) The production factor that increases the risk of rice production is the seed factor. Variable land area, fertilizer, labor and pesticides are factors that can reduce or reduce the risk of rice production.

Abstract

Chili is an inflation-forming commodity (volatile food). Prediction of chili price time series data using the ARIMA model approach has good performance for predicting chili prices in the future. The second highest average per capita consumption of chili for a month is Bengkulu Province, below West Sumatra Province. This shows that the level of consumption and demand for chili is relatively high in Bengkulu Province. High demand has an impact on the price volatility of chili. The volatility analysis illustrates the standard deviation or diversity of chili prices that fluctuate over a certain period. Based on the description above, it is necessary to conduct research on the analysis of chili price volatility in Bengkulu Province. This research uses data sourced from the National Strategic Food Price Information Center. chili price volatility analysis using the ARIMA model with the help of R studio software. ARIMA models are suitable for time series data. The stages in this study were stationarity test, building the ARIMA model, selecting the best model, evaluating the model, identifying the ARCH effect and building the ARCH GARCH model, and calculating the volatility value. If there is no ARCH effect, there is no need to create an ARCH GARCH Model. the output of this research was the form of an international conference. The results of the data forecast using the ARIMA model (1,1,2) show prices that are relatively stable but have an upward trend. This shows that the level of volatility can be controlled and this is reinforced by the results that the model has no ARCH effect. The absence of an ARCH effect means that the data is still considered to have relatively the same diversity of variance and is in line with a relatively small volatility.

Badan Riset dan Inovasi Nasional


Abstract

Abstract
Quality seed is critical in rice farming because they are a determining factor in increasing rice productivity. Seeds must always be available and easily accessible to farmers in terms of quantity and quality. Therefore, it is essential to assess the rice seeds production and financial feasibility of the seeds production business. The study was carried out in Konawe Regency, Southeast Sulawesi, Indonesia, in 2021. The study area includes nine hectares of rice growing, involving nine farmers who planted the Mekongga cultivar. Among the nine farmers, six were rice seed producers, and three were rice non-seeds producers (consumable rice producers). Each farmer cultivated rice in an area of one hectare. The study reveals that rice seed production is profitable and feasible for businesses. It was shown by the R/C ratio of rice seed production higher than rice non-seed production, 2.83 and 2.27, respectively. The rice seed production also performed a high value of MBCR 4.71. The Rice seed production business is relatively insensitive to the changes in prices and the decline of seed production, although there was a decrease in production by 20% and an increase in production inputs by 20%. Therefore, the rice seed production business needs to be encouraged for smallholder farmers to support seed self-sufficiency.
