Abstract

Water gate operation in irrigation systems is generally performed manually, which may delay responses to changes in water level. Such conditions can result in inefficient water discharge regulation and increase the risk of water overflow. This study aims to design and develop a prototype of an automatic irrigation sluice gate system using an ultrasonic sensor based on an ESP32 microcontroller. The research consisted of system design, hardware assembly, microcontroller programming, and prototype performance testing. The ultrasonic sensor was employed to measure water level changes, while the ESP32 processed the acquired data to control a servo motor as the gate actuator. Experimental results demonstrated that the proposed system responded rapidly and stably to variations in water level with satisfactory measurement accuracy throughout the testing range. The implemented control mechanism successfully operated the sluice gate automatically according to water level conditions. Therefore, the proposed system has the potential to improve irrigation management efficiency while reducing human error associated with manual gate operation.

Abstract

Coffee is a vital plantation commodity in the national economy. South OKU Regency has emerged as the leading coffee producer in South Sumatra Province, with a total production of 50,854 tons. This study aims to analyze the production response toward the increase in coffee prices in South OKU Regency. The hypothesis in this study was tesed using multiple linear regression analysis. Based on the results of the coefficient of determination (Model Summary), an R-Square value of 0.812, or 81.2 percent, was obtained. This value indicates that the variables of land area ($X_1$), fertilizer quantity ($X_2$), production ($X_3$), and pesticides ($X_4$) collectively explain 81.2 percent of the variation in coffee price changes ($Y$) in South OKU Regency. Meanwhile, the remaining 18.8 percent is influenced by other factors not accounted for in the model.

Abstract

Farmer regeneration is a strategic response to the agrarian crisis in Indonesia, where youth participation in agriculture remains limited. To address this challenge, the Ministry of Agriculture introduced the Young Agricultural Entrepreneurial Development Program (PWMP), which provides capital assistance to young farmers. Despite its potential, the program’s sustainability has been questioned, requiring empirical evaluation. This study employed a quantitative approach to analyze business characteristics, challenges, turnover, networking practices, and sustainability prospects of PWMP beneficiaries. Data were collected through questionnaires distributed to 100 participants, with 73 valid responses obtained between November and December 2024 across several provinces. Findings show that most PWMP-supported enterprises are on-farm businesses (53%), with an average duration of 3.7 years, and are concentrated in Central Java. Major constraints include high dropout rates due to alternative employment choices (48%), low turnover with 44% reporting earnings below IDR 2,000,000, and limited collaboration, as 57% lack business partners. Nevertheless, 52% of enterprises demonstrate potential for sustainability. The study concludes that PWMP has engaged youth in agricultural entrepreneurship but faces structural and managerial challenges. Strengthening the program through mentorship by successful agricultural entrepreneurs is recommended to enhance knowledge transfer, resilience, and long-term viability of youth-led agribusinesses.

Abstract

The oil palm industry plays an important role in Indonesia’s economy. One of the key issues in plantation management is the utilization of Palm Oil Mill Effluent (POME). This study aims to analyze the differences in Fresh Fruit Bunch (FFB) production between land application and non-land application areas at PT Perkebunan Nusantara IV Regional III Sei Garo Estate. This study used a quantitative comparative method with a time series approach based on secondary data from 2022–2025. Variables observed included average bunch weight (kg/bunch), number of bunches (bunch/ha), and FFB production (ton/ha/semester). Data analysis included descriptive statistics, Shapiro–Wilk normality test, and Independent Sample t-test. The results showed that average FFB production in land application areas (10.29 ton/ha/semester) was slightly higher than non-application areas (10.06 ton/ha/semester). However, statistical tests indicated no significant differences in average bunch weight (p=0.945), number of bunches (p=0.068), and FFB production (p=0.881). It is concluded that POME application tends to increase production, although the effect is not statistically significant

Abstract

The global paper industry faces a structural challenge due to excessive dependence on wood as its primary raw material, contributing to accelerated deforestation and tropical forest ecosystem degradation. Amid these environmental pressures, utilization of lignocellulosic biomass from plantation waste has emerged as a strategic and sustainable alternative. Indonesia, the world's largest palm oil producer, generates massive volumes of palm leaf waste that remain largely underutilized. This study aims to analyze the potential of oil palm leaves (Elaeis guineensis Jacq.) as an alternative raw material for paper production, encompassing biomass availability. An experimental laboratory approach was employed using NaOH delignification at 100°C for 60 minutes, followed by sheet formation and testing at two composition variants: 100% oil palm leaves and a 50% oil palm leaves–50% recycled pulp blend. The 100% leaf paper exhibited a coarser texture suitable for art and craft applications, while the blended composition produced more homogeneous sheets with superior mechanical strength for eco-packaging. These findings confirm that oil palm leaves represent a technically feasible, economically advantageous, and environmentally sustainable biomass feedstock as a partial wood substitute in the paper industry.

Abstract

Food is a fundamental human right guaranteed by the 1945 Constitution. Although South Sumatra is a major rice producer, Ogan Komering Ulu (OKU) Regency still faces nutritional and poverty challenges, with a Desirable Dietary Pattern (DDP) score of 88.4, which remains below the ideal national standard of 100. This study aims to analyze the influence of food availability and food access on the food security of poor households in OKU Regency. Using a quantitative survey method with 100 respondents, data were analyzed using multiple linear regression. The results indicate that both food availability and food access have a positive and significant influence on the food security of poor households, with food access providing a greater contribution.

Abstract

This study investigated the effect of the sterilization time of Fresh Fruit Bunch (FFB) on the Free Fatty Acid (FFA) content in Crude Palm Oil (CPO). It evaluated its implications for sterilization asset performance. A laboratory-scale experiment was conducted using a manual steam sterilizer heated by a gas stove, resulting in fluctuating sterilization temperatures. Three sterilization durations (30, 45, and 60 min) were tested, each with two replicate groups. Crude oil was extracted using a hydraulic press, and FFA content was determined using alkali titration 0.2 N NaOH and phenolphthalein indicator. The results showed considerable variation in FFA content among treatments. The lowest FFA value (2.50%) was obtained in the 60-min treatment and was the only result that complied with the Indonesian National Standard (SNI 01-2901-2006), which limits FFA content to 5.00%. In contrast, the highest FFA values reached 13.13% and 13.30% in the 45-min and 60-min treatments, respectively. These findings indicate that temperature instability during sterilization had a greater impact on FFA formation than sterilization duration. From an asset management perspective, sterilization equipment is a critical asset whose operational performance directly influences product quality. Therefore, maintaining stable sterilization temperatures is essential for minimizing FFA formation and ensuring consistent CPO quality.
