THE EFFECTIVENESS OF THE SOIL IMPROVEMENT FORMULA WITH BIOCHAR IN THE PRODUCTION OF MINI SHALLOT ON THE DRY LAND IN THE EAST LOMBOK DISTRICT Muji Rahayu (a*), Retno Pangestuti(a), Suriyadi (b) a) Research Center for Horticultural and Estate CropsCibinong Science Center, JL. Raya Jakarta Bogor, Cibinong, Bogor, Indonesia 09mujirahayu[at]gmail.com b) Food Crops Center, Cibinong Science Center, Jl. Raya Jakarta-Bogor, Cibinong, Bogor,indonesia Abstract The decline in soil fertility indicated by the degradation of organic matter occurs almost on agricultural land, it is inseparable from the intensification of crop production practices including the provision of chemical fertilizers and the lack of recycling of agricultural waste. Soil composed of thin organic matter impairs plant growth and productivity. In order to prevent the spread of soil damage, soil protection is required, including through the addition of soil improvers. Soil amendment materials can come from a variety of sources, including plant biomass, manure, char from agricultural waste (biochar), and others. This study compared soil amendment formula (Biochar charcoal shells, manure, and plant biomass) in influencing onion mini-bulb yield and dryland quality. Mini bulbs are small bulb bulbs produced as seeds from TSS propagation and are expected to be an innovation to meet the seed shortage. The design used a two-factor factorial randomized block, the first factor was the soil amendment formula (biochar, manure and biomass), the second factor was TSS varieties (Tuk-tuk, Sanren and Trisula). The study was conducted from April to July 2017 in East Lombok Regency on dry land with Inceptisol soil type. The results showed that the use of biochar in the Trisula cultivar produced the highest number of mini-tubers, 4.5 tubers/seed from TSS compared to the cultivars of Sanren (1.8 tubers/seed from TSS) and Tuk- Tuk (1.2 tubers/seed from TSS). The use of biochar improves the soil chemical quality (C-organic, P-available and CEC) on dry soils.

Effect of seed size and pod position of clove (Syzigium aromaticum) to seed viability Melati and D Rusmin Research Center for Horticultural and Estate Crops. National Research and Innovation Agency Indonesia Abstract Abstract. Cloves are commonly propagated generatively using true seed. One of the factors causing the lack of qualified clove seeds is farmers^ low awareness of using high-quality seeds. Farmers usually do not produce seeds- in particular, they obtain seeds from their trees without exclusively separating trees for making seeds and flowers. The seeds are harvested from all the flowers randomly without considering the pod^s position and size. This study aimed to evaluate effect of pod position and size on clove seed viability. The research was conducted at the Glass House of Indonesian Spices and Medicinal Crops Research Institute, Indonesia, from August to December 2018. The study was arranged in a completely randomized design with two factors. The first factor was the seed size : &#8805- 0.9 g and < 0.9 g. The second factor was pod position : (a) the pods exposed to morning sun, (b) pods exposed to afternoon sun, and (c) pods unexposed sun (hidden). The pods originated from selected mother trees from Kayu Aro, West Sumatra. The results showed that seed size &#8805- 0.9 g and pods exposed to the morning sun had higher viability, as indicated by the high seed growth rate, vigor, and better plant growth than other treatments.

Land Suitability Study for the Development of Rice Production in Moruku Village, Papua Pegunungan Province to Support Food Security Untari (a*), Parjono (b) a) Department of Agribusiness, Faculty of Agriculture, Musamus University, Merauke-South Papua *untari[at]unmus.ac.id b) Department of Agricultural Engineering, Musamus Faculty, Musamus University, Merauke-South Papua Abstract Yahukimo Regency is one of the regencies in Papua Island which has high food insecurity. Basically, the staple food of the local people, who are generally local people, are tubers. However, changing consumption patterns from tubers to rice makes it one of the challenges and problems for local governments to ensure the sustainability and safety of food ingredients because 99 percent of rice stocks come from outside the region with prices reaching IDR 60,000 per kg. The purpose of this study was to determine the chemical and physical quality of the soil in the area of food crop cultivation development, as well as engineering recommendations for the development of rice cultivation technology based on the results of soil quality analysis in the research area. The research was conducted in Moruku Village, Dekai District, Yahukimo Regency using a descriptive qualitative research approach using an experimental method. Analysis of the physical and chemical properties of the soil was carried out at the Bogor ICBB Laboratory. The results showed that the organic C content in the soil was included in the S1 class, meaning that it was suitable for rice cultivation. However, the acidity level and indications of copper (Cu), Iron (Fe), and Zinc (Zn) levels are very high. While the results of the analysis of nutrients available on the parameters Total N, P2O5 and K2O are all included in class S1, meaning that the available nutrients in the soil are suitable for the development of rice cultivation. For this reason, it is recommended that technological engineering be carried out, namely with a soil washing system on agricultural land, giving dolomite lime, using organic fertilizers, and choosing varieties that have a level of adaptation and tolerance to high acidity. The novelty in this study is that there are soil chemical and physical contents which can be further identified as an effort to find out the potential for new natural resources in the research area.

Chickens that have been infected with MG are stated to have a higher susceptibility to other disease agents. Therefore it is important to monitor the presence of MG in livestock. Monitoring through serological tests is the easiest option to apply. Rapid Agglutination Serum (RSA) is an option because of its fast and inexpensive application. In addition, ELISA has also been used to confirm the RSA test. This study aims to compare the suitability of two serological tests, namely the RSA and ELISA. Serum samples of 155 taken from laying hens were tested by RSA and ELISA. RSA test results obtained 99 (63.9%) seropositive and 105 (67.7%) ELISA seropositive. As many as 68 (64.8%) were seropositive on the RSA and ELISA tests, while 19 (38%) were seronegative. The proportion of conformity by McNemar test between the RSA and ELISA tests did not show a significant difference of 0.545 (P>0.005). The kappa value between the two serological techniques was low (k=0.027). The statistical analysis results of these two serological tests show that these two tests can be used as initial monitoring for screening for MG.

Influence of Toposequence on Soil Quality of Sugar Cane Plantation Areas in Bombana Regency, Indonesia Aprilia Herniyanti(a), Darwis Suleman(a*), Namriah (a), Sahta Ginting(a), Syamsu Alam(a), Dewi Nurhayati Yusuf (a), Resman (a) a)Department of Soil Science, Halu Oleo University, Kendari 93232 *Email: darwis_suleman[at]yahoo.com Abstract The intensive land use across the toposequence of sugarcane plantation has the potential to reduce soil quality, particularly due to the hazardous effect of erosion. Therefore, it is necessary to periodically evaluate the physical and chemical properties of the soil. The study was performed on Inceptisol in a sugarcane plantation area and aimed to investigate the effect of topography on soil quality. The soils sample were taken across the physiographic position (i.e., upper, middle and bottom) of the study area. Nine soil samples were collected at 0-20cm depth, then composited into three samples according to the toposequence and analyzed using standard procedures. Among all the soil properties, texture, pH, organic-C, total-N, available P and K were varied along the toposequence. It was observed a moderate soil quality index (SQI) at the bottom and upper of study site with a value of 0.54 and 0.44, respectively. Meanwhile, the low SQI was noted at middle (0.36). In the present study, the most crucial factors determining the variation in SQI were the soil texture, organic-C and soil pH. The finding suggest the need of appropriate land use strategies and sustainable soil management practices to improve soil conditions in sugarcane plantation areas.

Improving Water Seeding Establishment System in Rainfed Lowland Rice Zuziana Susanti, Priatna Sasmita and Zaqiah Mambaul Hikmah Research Center for Food Crop, National Research and Innovation Agency, Cibinong Indonesia Abstract Rainfed lowland is the second largest rice field in Indonesia after irrigated areas which covered 1.4 million ha. Rainfall is the main source of water thus farmers do not move out the water out of the field even during broadcasting to ensure its availability until harvest. As consequences water-seeding system is the most popular rice establishment. An experiment aims to determine the use of iron-coated seed in improving the growth and yield of rice had been conducted in South Sulawesi, Wajo during wet-season 2018. The study was design in split-plot with 4 replication. The main plot was planting system comparing between transplanting at 21 days after sowing and water-seeding system with iron coated seeds. The subplot was fertilizer rate which were 100% of fertilizer recommendation, 75%, 50% and 25%. Transplanting system resulted in significantly higher grain yield at average 6.01 t/ha compare to broadcasting at 4.98 t/ha. At 100% fertilization from the recommended dosage, the net income in transplanting significantly higher by 22% compared to the broadcasting. Consistently even though the fertilizer dosage is reduced to 75% and 50% of the recommended fertilizer dose, the net income in the transplanting system is always higher due to the costly daily labor.

Social Capital of the Local Community in Forest Conservation for Disaster Mitigation Sudirman Daeng Massiri (a*), Hendra Pribadi (a), Anwar (a), Golar (a), Naharuddin (a), and Hamzari (a) a) Forestry of Faculty, Tadulako University, Jalan Soekarno Hatta Km 9 Palu 94117, Indonesia * sudi_untad[at]yahoo.co.id Abstract Local communities living around forest areas are vulnerable to hydrometeorological disasters. On the other hand, some local communities with high social capital can conserve forest areas for disaster mitigation. For this reason, the government and several donors promote community-based forest conservation programs for disaster mitigation. However, several researchers have also revealed that high social capital could not encourage collective action in forest conservation. This research applying a descriptive approach to the community of Salua Village, Kulawi District Sigi Regency, revealed that high structural social capital could not create collective action in forest conservation for disaster mitigation, even though most every year these villagers face the problem of floods and landslides. The structural social capital of the Salua village community was moderate to high in terms of forest conservation but had cognitive-social capital in the moderate to low category. Forest conservation and disaster mitigation programs have only been carried out by elite groups in the village but have not involved community groups that interact directly with forest areas. This study recommends that forest conservation and disaster mitigation programs be planned by involving community groups that interact directly with forest areas.

Abstract Future demand for maize will not be easily met due to climate change and its development using marginal soils that are stressed by salinity. This study aims to identify the genetic parameters of corn plants under high salinity stress. The research was arranged in a randomized completely block design (RCBD) consisting of six local maize cultivars, namely Gento, Lanca, Pulut, Lokal, Lei, and Sigi Merah. Each treatment was repeated four times. The results showed that two traits had a high coefficient of genotypic diversity, four traits had a high coefficient of phenotypic diversity and six traits had high heritability and genetic progress. Plant height, the greenness of the leaves, age of male flower release, age of blooming female flowers, the position of the ear, harvest age, length of cob without stalks, and diameter of the cob were positively and significantly correlated with yield. Plant height and cob height can be used as criteria for increasing maize yields through indirect selection. In future studies suggest that various local maize cultivars can be applied to situations of high salinity stress.

Local Climate Variability Associated to Sustainable Agriculture at Rain Shadow Areas of the Mount Rinjani and Tambora in West Nusa Tanggara Mahrup , AB Baharuddin, Mulyati, LE Susilowati, Padusung and Fahrudin Dept. of Soil Science, Agriculture Faculty, Mataram University Abstract Abstract. Local climate variability is driven by solar energy received on the earth surface and about 30 percent reflected back to the atmosphere. Climate variables affected by the solar energy are, temperature, atmospheric pressure, relative humidity, wind and rain which are all associated to agriculture. In addition, mountains play a significant role in affecting local climate and inducing rain shadow areas which are typical of dry land agriculture. A descriptive research was conducted to study variability of local climate variability associated to direct normal solar irradiation (DNI), and its possible impact on sustainable agriculture at rain shadow areas of Mt. Rinjani in Lombok and Tambora in Sumbawa, West Nusa Tenggara. The results show that the intensity of DNI was relative similar at both sides of the Mt. Rinjani where there was 13.2 MJ/m2 day at northern side, and 13.1MJ.m-2 day at southern side. While at Mt. Tambora, there was 13.6 MJ/m2 day at northern side, and 15.6 MJ/m2day at southern side. The DNI was relatively high in low lands, 16.6 MJ/m2 day and 17.3 MJ/m2 day for Lombok and Sumbawa respectively. At medium lands it was 12.4 MJ/m2 day and 13.9MJ/m2 day for Lombok and Sumbawa respectively. At high lands it was 10.4 MJ/m2 day for Lombok and 12.4 MJ/m2 day for Sumbawa. ETo, air and soil surface temperature were relatively high at rain shadow areas located at northern side of the Mt. Rinjani, and at the southern side of Mt. Tambora. In conclusion, the intensity of DNI was not significantly affected by aspect factor of incoming light relative to the both mountains. The Mountains had affected the variability of local climate depending on direction of wind bearing water vapor heading to the mountains. Rain shadow areas had been performed to the north from Mt Rinjani and to the south from Mt. Tambora.

Spatial Metrics of Deforestation in Central Sulawesi, Indonesia Syamsu Rijal, Daud Malamassam, Munajat Nursaputra, Chairil A Hasanuddin University Abstract Climate change has become an environmental issue that has received the most attention because it affects all aspects of life. One of the factors causing climate change is deforestation which continues to occur, especially in tropical countries like Indonesia. Indonesia is a country that has a high rate of deforestation that occurs in large islands including the island of Sulawesi as the Wallacea Region. Central Sulawesi Province has had the largest area of deforestation among other provinces on Sulawesi Island in the last three decades (1990-2020). Analysis of the rate of deforestation using the Geographic Information System shows that the highest deforestation rate occurred in Palu City at 2.16% (1990-2020), even in the last decade (2010-2020) the rate of deforestation was 3.31%. After that, it was followed by Banggai Islands Regency at 0.17%, while other districts were at rates below 0.1% (1990-2020). Palu City and Banggai Islands Regency are also a concern, further information after the rate of deforestation is the pattern of deforestation which is described through three metrics, namely Clumpiness Index, Contiguity Mean Index, and Patch Density which describes fragmentation using Fragstat software. Palu City has a clustered deforestation pattern and is entirely connected to each deforested area, but it has lower fragmentation. Banggai Islands District has fairly clustered deforestation, but does not have low connectivity between deforested areas, and tends not to be fragmented. Dealing with deforestation incidents in Palu City as a whole land area, and Banggai Islands Regency as a separate land area is different.
