Budidaya padi sawah dengan sistem irigasi tergenang merupakan sumber emisi gas metana (CH4) yang menyebabkan peningkatan pemanasan global. Pada umumnya, pengukuran gas metana dilakukan secara tidak kontinu dengan melakukan sampling dan analisis di lab menggunakan gas chromatography yang cukup mahal. Makalah ini menyajikan model jaringan syaraf tiruan (JST) untuk memprediksi gas metana yang diemisikan dari padi sawah berdasarkan data parameter lingkungan biofisik yang mudah diukur seperti kelembaban tanah, suhu tanah, dan daya hantar listrik (DHL) tanah. Untuk melakukan validasi model, percobaan dilakukan di dua tempat berbeda yaitu di Kanagawa dan Bogor. Perlakuan difokuskan pada pemberian air yang berbeda dengan menggunakan prinsip budidaya system of rice intensification (SRI). Model JST yang dikembangkan menggunakan algoritma back propagation dengan layer masukan terdiri atas 3 node: kelembaban tanah, suhu tanah, dan DHL tanah, sedangkan gas metana dijadikan sebagai keluaran. Dari hasil pembelajaran model JST didapatkan korelasi antara gas metana hasil pengukuran dan model cukup tinggi dengan nilai R2 sebesar 0.93.Kata kunci: emisi gas rumah kaca, gas metana, jaringan syaraf tiruan, lingkungan biofisik, padi sawah.

This research aims to design a control system to keep the water level and soil moisture at a level that is suitable to the plant requirment and determines the optimum water level and soil moisture in each growth phase of paddy field cultivation. The water level control system was formed based on on-off controls system using Arduino Uno ATMega328P microcontroller. When the sensor gives input that the water level is below the set points, then microcontroller will command the irrigation valve to open and the drainage valve to close. The volume and time of irrigation and drainage control are dependent to set point. Set point was controlled based on water regime treatment. Water regime consisted of three treatments, which are wet regime (RB), slightly wet regime (RAB), and dry regime (RK). The research result showed that control system was very effective and efficient in controlling the water regime according to the control algorithms. Besides, the research result showed that the water regimes affected the plant growth, land productivity, and water productivity. Treatment of wet regime (RAB) gave the highest number of tiller (138 tillers), yield 194.7 g/hill (equal to 21 ton/ha with assumption of 30 cm x 30 cm spacing) and water productivity 3.16 kg/m3.

This community engagement program aimed to empower rural women from the PKK group in Mendalo Darat Village, Indonesia, through training in aromatherapy soap production using locally sourced citronella essential oil. The program involved socialization sessions, hands-on training, and mentoring to enhance participants’ knowledge and practical skills. Participants were actively engaged in the entire soap-making process, including formulation, mixing, molding, and packaging. The training improved participants’ technical competencies and increased their interest in home-based entrepreneurship. Additionally, participants were introduced to the use of digital media for product promotion, marking a significant step toward digital literacy and market access. While the program successfully boosted initial skills and confidence, it also revealed a need for further training in business management and sustainable marketing practices. This initiative demonstrates the potential of combining local resources with skill-building to support women's economic empowerment in rural settings. Future programs should include entrepreneurship development and SME partnerships to strengthen long-term sustainability and impact.

Oyster mushrooms have a delicious taste and contain nutrients. One of the popular oyster mushrooms in the community is white oyster mushrooms (Pleurotus ostreatus). The content and characteristics of oyster mushrooms are influenced by the age of harvest. This study aims to determine the effect of oyster mushrooms harvesting age on physical and chemical properties. This study used a completely randomized design. The treatment is the age of harvesting namely 2, 3, 4, and 5 days after budding. Each experimental unit was repeated 3 times. This research consisted of nursery, incubation, maintenance, and harvesting oyster mushroom. The results showed that harvest age has a significant effect on the height, diameter of the hood and the wet weight but has no effect on the number of stalks and water content of white oyster mushrooms

The level of physiological maturity of the plant, productivity at harvest, and content in the material are all determined by harvest age, which is a component that is strongly tied to the phase of plant growth. Oyster mushrooms will undergo biochemical changes as they mature, but they will also change physically when they are harvested, especially in terms of color, texture, size, form, and the sections that may be eaten. This study aims to discover the optimal harvest age for yellow oyster mushrooms (Pleurotus citrinopileatus) based on their physical, chemical, and antioxidant activity. It also examines the impact of harvest age on the physical, chemical, and antioxidant activity of yellow oyster mushrooms (Pleurotus citrinopileatus). The design of this investigation was entirely random. This study used two harvest periods of yellow oyster mushrooms with harvest ages of 2, 3, 4, and 5 days after the appearance of pinheads as the treatment. Three times each experimental unit is repeated. The nursery, incubation, upkeep, and harvest of yellow oyster mushrooms comprised the study. The findings demonstrated that wet weight, rendemen, total phenol, and antioxidant activity of yellow oyster mushrooms were significantly influenced by harvest age. It is advised to harvest the yellow oyster mushroom on the third day after the appearance of pinheads.

High rainfall and changes in land cover occurring in the Batang Tabir sub-watershed have an impact on surface runoff and increased river flow, triggering flooding and causing road access to be submerged and damage to infrastructure around the river. Therefore, it is necessary to review the flood flow design calculations in the Batang Tabir Sub-Watershed to assess the potential magnitude of flood flows and establish the parameters required for water infrastructure planning. The methods commonly used for flood flow calculations are the Rational Method and the Nakayasu HSS Method. These methods are preferred due to their simplicity, as they only require river data and rainfall data. The selection of an appropriate method for calculating flood discharge must be validated with measured river discharge data. This study aims to determine the design flood discharge method that can be applied to the Batang Tabir Sub-Watershed. This study was conducted by comparing the flood discharge of the Rational and HSS Nakayasu methods with measured flood discharge using frequency distribution based on relevant statistical parameters. The results of the flood discharge calculations using the Rational method for a return period of 2–100 years are closer to the measured flood discharge, with the Rational method yielding a flood discharge of 494.05–1,385. 48 m³/s, the flood discharge using the Nakayasu HSS method for a return period of 2–100 years was 769.32–2,157.41 m³/s, and the measured flood discharge for a return period of 2–100 years was 375.22–1,337.44 m³/s. The validation and evaluation results show that the smallest error value (VE) is found in the Rational method, which is 9%, with the Nash Sutcliffe Efficiency (NSE) value falling into the very good category at 94%. Meanwhile, the Nakayasu HSS method yields the largest error value (VE) at 69%, and the NSE value falls into the unsatisfactory category at 17%. Therefore, the Rational method has a better level of suitability and can be used as a reference in infrastructure planning in the Batang Tabir Sub-Watershed.
