Abstract

The East Kalimantan Provincial Government has designated North Penajam Paser Regency as one of rice food supports for the National Capital City (IKN) of the Archipelago. This decision is based the domestic production which met and even exceeded demand in 2020. One step to support rice production is to identify land with the greatest potential for cultivation. Therefore, this study aimed to analyze land suitability zonation for rice production using the criteria of climate, topography, and soil properties, as well as infrastructure. Land suitability was evaluated using simple additive weighting (SAW), multicriteria, and GIS methods taking into account the factors of drainage, soil depth, texture, type, rainfall, temperature, slope, distance from road, distance from river, and land use land cover. Suitability zonation (classes) were arranged based on land suitability classification outlined by the Food and Agriculture Organization (FAO, 1976) in Minister of Agriculture Regulation No. 79 of 2013, namely Very Suitable (S1), Moderately Suitable (S2), Marginally Suitable (S3), Not Suitable (N1). The results showed that the areas classified as highly, moderately, marginally, and not suitable were 4,960 ha (3.1%), 103,738 ha (65.5%), 44,889 ha (28.4%), and 4,708 ha (3.0 %) respectively.Received:2024-02-01 Revised:2024-09-26 Accepted:2025-03-11 Published: 2025-04-27

Abstract

Agriculture in Indonesia is a vital sector that can fulfill food needs and provide livelihoods. However, agriculture also contributes to greenhouse gas (GHG) emissions. Indonesia's agricultural sector contributes around 14% of emissions globally and 7% nationally. Greenhouse gas emissions such as methane gas CH4, carbon dioxide CO2, and nitrous oxide N2O are generated from agricultural activities ranging from land preparation, fertilization, transportation of agricultural products, to processing in factories. These greenhouse gas emissions influence the climate change that occurs and affect the increase in temperature and rainfall patterns. In mitigation efforts, this study noted several steps taken. Energy conversion, such as the use of biogas from animal manure can reduce CH4 emissions and the use of pellets from palm waste processing can reduce CO2 emissions. Reforestation with special carbon-absorbing plants to reduce CO2 emissions. The use of organic fertilizers as a partial replacement for inorganic fertilizers is useful in reducing CH4 and N2O emissions. Through this systematic review, it is expected to contribute to the understanding of the role of the agricultural sector in greenhouse gas emissions in Indonesia and provide insight into mitigation efforts that can be applied in achieving sustainable agriculture.

Abstract

Sustainable agriculture is one of the latest innovations in the agricultural sector. This should consider the importance of environmental sustainability in its application in agriculture to prevent and minimize land damage and environmental pollution. One of the main pollution cases on agricultural land is the excessive use of chemical fertilizers to promote and maintain plant growth. Besides, providing plant nutrition can be done with the presence of ecoenzymes. Ecoenzymes are the result of complex fermentation of organic waste which can be used as plant growth and nutrient enhancers. This review study aimed to examine the effectiveness impact of providing ecoenzymes on various cultivated plants in Indonesia. Based on the results of the review, the ecoenzymes can help the growth of horticultural, ornamental, food, and annual plants which are also influenced by various characteristic factors, plant type, and concentration dose. Dosing ecoenzymes also depends on the use of additional fertilizer during the planting period.

Abstract

The application of this technology aims to develop a pyrolysis reactor for Organic Waste Slurry, designed to convert urban organic waste into high-quality biochar, with a self-sufficient pressure control system for energy efficiency. The methodology employed in this study includes performance testing of the pyrolysis reactor equipped with automatic temperature control and a system to utilize pyrolysis gas as an internal fuel source. Organic waste was processed at pyrolysis temperatures ranging from 400–500°C to produce biochar with a high fixed carbon content. Testing was conducted on several soil samples with added biochar to assess its impact on water retention and nutrient availability. The results of the study indicate that the biochar produced from the Organic Waste Slurry reactor has a fixed carbon content of around 65–70%, along with optimal physical and chemical stability for use as a soil amendment. This biochar increased the cation exchange capacity (CEC) of the soil by up to 30% and improved soil water content by 15% compared to controls without biochar. Quantitatively, the reactor successfully reduced the volume of organic waste by 50% and generated biochar that enhanced soil fertility, positively impacting urban agricultural productivity. The mechanisms and processes in the Organic Waste Slurry pyrolysis reactor were found to be effective as a solution for urban organic waste management, reducing carbon emissions, and improving soil quality sustainably. This technology shows a positive trend in energy efficiency and applications for environmental agriculture and food security.

Abstract

Increasing population and development has resulted in inappropriate land use within watersheds that increase soil erosion. One of the hydrologic models that can be used to predict erosion and soil and water conservation in a watershed is SWAT. This research was conducted to predict erosion and the guidance of soil and water conservation in the Yeh Empas Watershed. This research was carried out in several stages, including data collection, data analysis and map validation using the ROC (receiver operating characteristic) and AUC (area under curve) methods. Results revealed that Yeh Empas Watershed had a very light EHL (erosion hazard level) category was found in the downstream area with an annual erosion value of 0 – 14.68 t/ha. In the middle area, the EHL was categorized as light with an erosion value of 15.44 – 57.22 t.ha-1.y-1. The upstream area has moderate EHL with a value of 65.20 – 178.64 t.ha-1.y-1. The validation of the EHL map using the ROC method showed a result of 0.83. This value was classified as very good. It can be concluded that SWAT predictions can be used in estimating erosion and soil and water conservation scenario to reduce 85% erosion. Keywords: Erosion prediction, Soil and water conservation scenario, SWAT models, Yeh Empas Watershed.

Abstract

Utilization of degraded land, such as post-mining land, for agricultural purposes necessitates significant effort, particularly land and water management. This study focuses on estimating crop water requirements (CWR), a crucial step in evaluating suitable cropping patterns for agricultural development on post-tin mining in Bangka Island. The CWR and effective rainfall (EF) of rice, cassava, and peanuts were estimated using meteorological data between 2019 and 2023. The CWR was calculated using Penman-Monteith method, while EF was determined using the USDA SCS Method. The results indicate that average potential evapotranspiration (ETo) from 2019 to 2023 varied across years. The highest ETo values were predicted as 5.6 to 5.8 mm/day, while the lowest value was estimated at 4.3 mm/day. Rice and peanut cultivation require supplemental irrigation since EF is insufficient to meet CWR. Cassava, is more suitable, with EF generally fulfilling its CWR. This study provide useful information for developing adaptive strategies that account for the effects of climatic conditions and different cropping pattern, particularly in degraded areas. Furthermore, crop selection that is adapted to the degraded area offers a long-term solution for rehabilitating degraded areas. Keywords: Agriculture, Degraded soil, Irrigation, Yield.

Abstract

Coconut sap, increasingly recognized as a functional sweetener, is highly perishable and influenced by environmental conditions during postharvest handling, yet the specific impacts of microclimatic variables such as temperature and relative humidity (RH) on sap and sugar quality remain inadequately studied. This research investigates the effects of RH and temperature on key physicochemical parameters of coconut sap—pH, Brix, and density—and evaluates their influence on coconut sugar quality, focusing on moisture, ash content, and color. Sap was collected biweekly in Central Java over a five-week period and analyzed in conjunction with environmental data recorded using an IoT-based weather station. Increased RH was significantly associated with decreased sap pH (r = –0.482, p = 0.007) and showed a weak negative correlation with Brix. Density remained stable across varying RH levels. Although temperature showed visual trends in sap quality parameters, statistical analysis did not reveal significant correlations, likely due to the narrow temperature range during the observation period. Throughout sugar processing, TSS increased consistently across boiling, saturation, and oversaturation stages. Final sugar blocks maintained stable moisture (6–8%) and ash content (1.8–2.2%), with color variations reflecting Maillard and caramelization reactions. Maintaining RH below 85% is recommended to preserve sap quality and product consistency. Keywords: Coconut sap, Coconut sugar, Postharvest quality, Relative humidity, Temperature.

Abstract

Watersheds play an important role in the hydrological cycle to ensure water availability and support food security. Currently, many watersheds are experiencing degradation due to excessive agricultural practices without the implementation of soil and water conservation measures. This study aims to assess the potential of Vetiver crops (Chrysopogon zizanioides L.) for soil and water conservation as a nature-based solution for watershed protection.n. This research use Geographic Information System (ArcGIS) tools to analyze land suitability for Vetiver cultivation. A multi-criteria evaluation approach was applied using a scoring system based on key environmental indicators including rainfall, temperature, slope gradient, land use type, soil type, and organic matter content. The results indicate that most of the study area was classified as moderately suitable (61.98%) and marginally suitable (38.00%) for vetiver plants, with only 0.01% falling into the highly suitable and not suitable categories, respectively. The integration of spatial analysis and environmental indicators allowed for the identification of priority areas where Vetiver could be effectively implemented to enhance watershed resilience, mitigate erosion, and support sustainable land management. The finding of this study provides a reference for vegetation method development using crops with economic value which is suitable for tropical areas.
