Abstract
This study aimed to evaluate the effect of the addition of chestnut tannins as silage additives in complete feed on digestibility in vitro, conducted at the Dairy Livestock Laboratory, Faculty of Animal Husbandry, IPB University. The Complete Randomized Design with five treatments and five replications was used in the commercial complete feed silage. The treatments were P1 = complete feed, P2 = P1+ chestnut tannins 0.50% DM, P3 = P1+ chestnut tannins 1% DM, P4 = P1+ chestnut tannins 1.50% DM, P5 = P1+ chestnut tannins 2% DM, further ensilage for 30 days, dried, and ground with a size of 1 mm, then tested in vitro with a Random Design of Group 5 treatments and five groups based on the day of rumen fluid intake. The parameters measured were the pH of the post-incubated rumen, and the digestibility of rumen fermentation (DM, OM, CP). The data obtained was analysed based on a variety of analysis, and when inter-treatment had a real effect, it was followed by a test Duncan level of 5%. The use of chestnut tannins as silage additives to ensilaged complete feed exerts a noticeable influence (P<0.05) on digestibility and rumen fermentation products in vitro. The addition of 0.50% DM chestnut tannins resulted in higher values for DMD, OMD, and CPD with values of 56.6%, 52.9%, and 58.9%, respectively. The conclusion of this study is that the addition of 0.50% DM chestnut tannins in complete feed silage can increase the digestibility value of rumen fermentation in vitro.

Abstract
Erosion and sedimentation in the upstream area of the sub-watershed have resulted in a decrease in the quality of agricultural land, such as a decrease in soil fertility. This decrease in soil fertility is due to the loss of NPK nutrients that occur in the top soil. Erosion and sedimentation in the upstream area of the Mamasa Sub-watershed are caused by land degradation and forest conversion due to land expansion and shifting cultivation for the cultivation of cocoa, corn and coffee. The purpose of this study was to determine the amount of sediment in the Mamasa Sub-watershed, Mamasa Regency using the SWAT model. This research was conducted in the Mamasa Sub-watershed from June to September 2022 through several stages in the form of literature study, primary and secondary data collection. Then proceed with laboratory analysis, making a base map to the data analysis process. SWAT requires input data in the form of land cover, soil type maps, slope maps, and climate data. The SWAT simulation was carried out in the 2012 to 2021 timeframe. The sedimentation values obtained from the SWAT model were sediment values from 0.06 to 34.073.01 tons/ha (55.34%), sediment values from 34.073.01 to 95.323.59 tons/ha (23.27%), sediment value 95.323.59 to 225.951.47 (13.51%), sediment values 225.951.47 to 442.013.09 (6.23%), and sediment values from 442.013.09 to 1,415.454.83 (1.66%). Based on this research, it can be concluded that the highest average sediment is found in the downstream area with an area of 38,875.66 ha

Soil of organic carbon absorption is considered as one of the climate change mitigation strategies and is related to carbon storage in soil. The objectives of this study to identify soil carbon in forest and agriculture land use. This research was conducted in Tanralili Watershed. In this study, soil sampling was divided into three parts based on the depth, namely 0-20 cm, 10-20 cm, 20-30 cm with three repetitions using purposive sampling method. This research was carried out on seven types of land use (corn plantation, mixed gardens, pine forests, mixed forest, cloves plantation, horticulture, and coffee plantation). The physical and chemical properties of the soil observed in laboratory are Bulk density, Carbon organic soil, nitrogen, and C:N ratio. The result showed that the average soil carbon in the land use of corn plantation (UL1), corn plantation (UL2), Agroforestry (UL3), pine forests (UL4), mixed forest (UL5), cloves plantation (UL6), horticulture (UL7), and pine forest mixed coffee plantation (UL8) were 72 ton/ha, 70 ton/ha, 76 ton/ha, 80 ton/ha, 96 ton/ha, 77 ton/ha, 80 ton/ha, and 43 ton/ha, respectively. Soil carbon accumulation, based on content of decomposed soil organic, was mostly found in the top soil layer around 0-10 cm. Soil organic matter storage can be seen from the C:N ratio. High C:N content will reduce the ability to absorb soil carbon.

Hasanuddin University
Abstract
Landslides are one of the most frequent disasters in Indonesia. The Tana Toraja Regency, specifically in South Makale District, has not been spared from landslides. Therefore it is necessary to map landslide-prone areas to support landslide disaster mitigation efforts in the study area. This study aims to map landslide-prone areas and to determine the factors that most influence landslide events in Makale Selatan. The method uses a spatial analysis method with an Analytical Hierarchy Process (AHP) weighting method, with parameters- slope, rainfall, land use, soil texture, soil type, and rock formation. The Results show the occurrence of landslides in Makale Selatan is strongly influenced by the slope, which has the highest weight with a score of 41% compared to other parameters. The extent of landslide vulnerability is dominated by landslide-prone areas, with a percentage of 51.72% of the total area of the study. Land use as a residential area is almost 50% in areas susceptible to landslides. The slope strongly influences the incidence of landslides in the study area. The level of landslide hazard in the study area is dominated by moderate susceptibility.

*) annisafadlilah012[at]gmail.com
Abstract
Global warming caused by various human activities results in increased concentrations of Greenhouse Gas (GHG) emissions. This causes the problem of climate change. One of the sources of Indonesia^s greenhouse gas (GHG) emissions comes from the agricultural sector. Methane (CH4) is the second most important greenhouse gas and has a global warming potential 25 times greater than CO2. Paddy fields contribute to GHG emissions due to the condition of the rice fields which are always flooded which produce gases such as CO2, N2O and Methane (CH4). This study aims to determine the effect of microbial abundance on increasing emissions of methane gas (CH4) in paddy fields. This research was conducted by collecting samples in the field with variations at 30th, 60th, and 90th day after planting (DAP). The results of laboratory analysis showed that the results of C-Organic analysis were 1.45-2.56%, the results of soil microbial abundance analysis for the total bacterial population ranged from 1.2 x 104 - 6.3 x 105 (CFU/g) and the total population fungi ranged from 1.5 x 104 - 5.0 x 105 (CFU/g), and the results of analysis of CH4 at 30th DAP sampling from the three sample points ranged from 181.79 - 617.74 (mg/ m2/day). For the 60th DAP sample from the three sample points it ranges from 240.13 - 1888.57 (mg/m2/day). For the 90th DAP sample from the three sample points it ranges from 523.33 - 1959.90 (mg/m2/day). The results of the analysis of methane (CH4) emissions in one growing season show different values of methane emissions at different locations and sampling times.

Abstract
Climate change that has hit Indonesia lately has had a lot of influence on farming. Sidrap Regency, which is a rice center that is still very dependent on nature, also feels the impact of climate change. This study aims to identify the forms of climate change felt by rice farmers in Sidrap Regency which have an impact on the sustainability of their farming. The research method used is a descriptive method with survey techniques. The research was conducted in Maritengngae and Duapitue Districts, Sidrap Regency. The sampling method used simple random sampling of 40 respondents in each region. It was found that the climate change experienced by rice farmers in Sidrap Regency was high rainfall, erratic weather, hotter temperatures, tornado natural disasters and reduced water resources in several areas in Sidrap Regency. The high intensity of rainfall is most felt by rice farmers in Duapitue District, while rice farmers in Maritengngae District do not feel other climate changes other than temperatures getting hotter. This shows that the two sub-districts have different microclimates, even though they are still in the same area of Sidrap Regency, which will affect the sustainability of rice farming.

Abstract
Around 40 cocoa industries were established in Indonesia, and about 400 thousand kg of cacao beans were used for end-product. Deforestation decreases the productivity of cocoa beans and increases greenhouse gas emissions. Besides, 80% of cocoa fruit also consists of pod, shell, and pulp, contributing to residual biomass increment in cocoa industries. Research on cocoa biomass potencies has been carried out in cocoa plantations and the cocoa industry. Cocoa shells have several chemical compounds that benefit agriculture products and environments, such as minerals and nutritional compositions. Cocoa Nibs Shell (CNS), one of the by-products of cocoa processing, wastes about 13% of its production. Therefore, this research aims to give an overview and determine the potential use of CNS waste in agriculture by analyzing the bioactive compound in CNS to add more value to cocoa waste and reduce greenhouse gas emissions from the waste. The authors used X-Ray Fluorescence (XRF) to identify the bioactive compound in CNS. Subsequently, several bioactive compounds found in the XRF assay were P2O5, SO3, K2O, TiO2, MnO, Fe2O3, NiO, CuO, ZnO, Rb2O, SrO, BaO, Yb2O3, Re2O7. These bioactive compounds have a positive benefit to utilize in agricultue. MnO and Fe2O compounds are essential for fertilizer application. P2O5 and SO3 have potential benefits in crop protection. Moreover, CNS has a great characterization which is potential for biochar and bio-adsorbent on water irrigation treatment since it has carbon, nitrogen, and oxygen compounds. Those potencies are also essential to reduce industrial waste in cocoa and achieving sustainability.

Abstract
In the region of karst, there are valley areas that are used by the community as agricultural land. However, drought phenomena often occur in this area, so it is necessary to know the presence of water to support agricultural processes. This study aims to predict flow rates in several agricultural systems using the Soil and Water Assessment Tools (SWAT) model. SWAT was chosen because it can simulate the model with easy-to-obtain data. Required data such as Digital Elevation Model (DEM), soil type, and land cover to form a Hydrology Unit Response (HRU). Enhanced with climate data input to run SWAT Run. The scenario is done with Land Use Split in the HRU Definition menu. The results showed that forest vegetation defined as FRSE and FRST stored water better than AGRR and RICE agricultural lands. However, it is different for underground flow, that RICE can store better. The scenario results show a decrease in the value of surface runoff by 15.3% and an increase in lateral flow by 26% from the existing condition. The underground flow continued to increase but was not significant at 4.2%.

Abstract
The Indonesian government is currently trying to increase the productivity of agricultural land by building irrigation infrastructure. In addition, efforts need to be made to optimize the availability of agricultural water sources which continue to decline. The high rate of water loss in agricultural areas is a new challenge in efforts to increase the productivity of existing land. Calculation of potential evapotranspiration is one of the important factors in calculating plant water requirements. This can be used as a reference in providing irrigation water to agricultural lands in accordance with crop water needs. The main obstacle faced in determining the value of potential evapotranspiration is the very lack of availability of climatological stations which are the source of data in determining the value of potential evapotranspiration. This study aims to obtain an overview of the evapotranspiration potential value in one of Indonesia^s national food barns in Wajo district. The results show that the use of global climatological data provided by Merra-2 can be used as a reference in calculating the potential evapotranspiration rate in an area. The results of climatological data analysis in calculating the potential evapotranspiration rate in several areas adjacent to Wajo Regency can be used as a reference in predicting the potential evapotranspiration rate. Utilization of geographic information system technology in interpolating potential evapotranspiration values in several areas can provide a detailed description of location-specific potential evapotranspiration rates. The results of the calibration of global climatological data with direct measurement data in the field can provide information on the value of potential evapotranspiration in a spatial-based area.

Effects of Using Tractors and Providing Organic Materials on Soil Compaction on Performance of Corn Plants 〖-Suki Mariadi〗-^*, Iqbal, Sitti Nur Faridah
Hasanuddin University
Abstract
In Indonesia, most of the corn cultivation process is still done manually. This is not efficient because the need for labor in corn cultivation is quite large. Efforts to increase productivity and efficiency in corn cultivation are made by using agricultural tools and machinery. The use of agricultural tools and machinery in corn cultivation is carried out from the stage of tillage through planting, weeding, fertilizing, pest and disease control, and harvesting. This activity can have a negative impact on the physical and mechanical properties of the soil. The provision of organic matter can reduce the negative effects of the use of agricultural tools and machinery. In addition, the result of this research activity is an increase in corn productivity due to the addition of organic matter to the land.

Abstract
Watering is a very important thing at the plant nursery stage. Without proper watering, the growth of the seedlings will be disrupted. In the process of watering must pay attention to several things, such as watering time and water discharge. At this time, most independent smallholders do not understand how to use a rain gauge or what is often called an ombrometer. These farmers prefer to use the old way of looking at the state of the soil in the watering process rather than using an ombrometer. In this case, as we know, buying an ombrometer is quite expensive. An ombrometer is a rain gauge which is also often referred to as a rain gauge. This tool is installed in an open place without protection or shade so that rainwater will be caught directly by this tool. The unit used is millimeters with an accuracy of reading up to 0.1 mm. Currently, practical rain gauges that are self-made without using factory machines are still not validated. The purpose of this research is to the results of simple ombrometer (C) accuracy and precision tests compared to Observatory Ombrometers, Ordinary Ombrometers, and Automatic Weather Stations (AWS). The location of the research test was in the oil palm nursery area at the Research and Experimental Garden of the Yogyakarta Community Plantation Academy. Rainfall data were obtained from Nine Practical Rain Gauges (C), Observatory-type Ombrometers (A), Ordinary Ombrometers (B), and Automatic Weather Station (AWS). Statistical methods are used to test accuracy and precision. The results of the C test compared to AWS have a precision value of 95.9% and an accuracy of 88.7%. Comparison of C with A shows a precision value of 99.6% and an accuracy value of 98.3%. The results of testing C against B show a precision value of 99.5% and an accuracy of 97.5%.

Abstract
The equilibrium moisture content of sago flour is a quite important information, especially for predicting shelf-life of the product which can be affected by various factor, such as temperature, relative humidity, and packaging condition. This research was conducted to study the characteristic of moisture sorption isotherm and to determine the best mathematical equation model in studying the isotherm sorption characteristic of sago flour. Sago flour was stored in an incubator at humidity range of 10 to 80% with temperature variations of 30 C and 40 C. Humidity setting was done using various types of salt solutions. This study showed that all the sorption curves were found to be Type II. The higher the RH in the incubator, the higher the equilibrium moisture content of the material. Meanwhile, the water sorption capacity decreased with increasing temperature. Different models were fitted to the data, including Oswin, Chung Pfost, and Caurie model. The Chung Pfost model was found as the best model to represent the experimental data in water activity range 0.1 to 0.8.

Abstract
Kailan (Brassica oleraceae var. acephala) often also called to as Chinese broccoli or Chinese kale, is included in the group of leaf vegetable plants that have high economic value. Kailan plants contain nutrients that are quite complete and very good for health. In 100 grams of fresh kailan plants contain vitamin A, vitamin B1, fat, calcium, iron, magnesium and phosphorus. Increased air temperature and extreme weather that causes drought have an impact on decreasing food production. The decrease in the availability of soil water content is an environmental condition where plants do not receive sufficient water supply, so that plants cannot carry out the growth and development process optimally. This study aimed to evaluate the growth and yield of kailan plant on dusty clay soil for various field capacity water contents. The application of water supply is carried out at 60%, 40% and 20% of the water content of the field capacity for kailan plants during the growing period to harvest. The results obtained that the water content of field capacity in dusty clay: 36.50%. The decrease in the water content of the field capacity from 60% to 40% and 20% resulted in a decrease in plant growth respectively- plant height 9.07% and 39.95%, leaf area 43.42% and 60.09%, and fresh weight 46.86% and 78.53%.

Abstract
Background. The main problem of damage to land resources in watersheds is caused by erosion due to land conversion. Erosion occurs due to several factors, namely rainfall, topography, soil, vegetation, and human activity. Aims. Knowing the spatial distribution of the hydrologic response unit (HRU) and analyzing the level of erosion using the SWAT (Soil and Water Assessment Tool) in the Tanralili Sub-watershed, Tompobulu District, Maros Regency, South Sulawesi Province. Method. The erosion rate was analyzed using the SWAT method with several stages: delineation of watershed boundaries, analysis of HRU (Hydrological Response Unit), merging climate data and HRU, running SWAT and calibration and validation, and soil texture with hydrometer method, C-organic analysis with Walkley and Black method, and calculations of soil permeability by the permeameter method. Results. The research area has an average annual rainfall of 2,867 mm/year. The dominant soil characteristics have clay texture, C-Organic 0.70-1.98%, and permeability 0.06-2.75 cm/hour. The number of HRUs formed is 44 units. The erosion rate was divided into five classes, namely very light 23.06% (6.450,47 ha), light 13.09% (3,661,73 ha), moderate 9.34% (2.611,78 ha), heavy 11.21% (3.137,39 ha), very heavy 43,31% (12.116,42 ha). Calibration and validation obtained values of R2 (coefficient of determination), and NSE (Nash Sutcliffe) are 0.629 (satisfactory) and 0.64 (satisfactory). Conclusion. The class of heavy-to-very heavy erosion reached 54.51% of the total area of the Tanralili sub-watershed. It shows that the Tanralili Sub-watershed area needs to immediately apply conservation techniques to sustain the use of the Sub-watershed.
