Abstract

Agroforestry is a land use system that integrates agricultural and forestry crops in the same area, providing a balance between production and conservation for social, economic and ecological benefits. Farmers at the Lembah Bukit Besak Village Forest Institute, Tanjung Beringin Village, South Merapi District, have implemented this system. The research aims to identify planting patterns and composition of agroforestry plants, evaluate the most optimal plants to increase income, and formulate strategies for adopting the best planting patterns. This study used a census method to collect data from 75 farmers in the Rimba Bukit Besar Village Institution group. After conducting a sampling method using a purposive stratified random sampling method, 24 farmer respondents were obtained. The research results show two main planting patterns: a random mixture, applied by 66.67% of farmers, and tree along border pattern, applied by 33.33%. The most profitable crops are coffee, rubber, jengkol, durian and eggplant (Solanum melongena). The "Tree Along Border" pattern has proven to be more effective in preventing erosion and providing shade for plantation and vegetable crops compared to random mixture patterns which focus more on forestry and plantation crops. The strategy for adopting the best planting patterns includes the development of pilot demonstration plots, intensive counseling, dissemination of information on research results, as well as the involvement of the government and related agencies in supporting superior commodities. This approach is expected to increase farmers’ income and welfare in a sustainable manner. From the adoption of additional horticultural crop types, farmers’ income increased by 9.264 to 30.83 percent when compared to the application of a combination of plant types without horticultural commodities.

Abstract

Rice (Oryza sativa L.) is one of the main food commodities in Indonesia and has a strategic role in national food security. High quality rice production is a major factor in meeting the increasing consumption needs of the community. However, agricultural conditions in Indonesia still face various challenges, especially in rainfed rice fields which are highly dependent on rainfall and often experience problems in crop production. This research was conducted in Prabu Menang Village, East Merapi District, Lahat Regency, South Sumatra Province, from January to April 2024. The method used was quantitative research with a split plot design. The main plot was a combination of fertilizers consisting of three treatments: (1) NPK (300 kg/ha), Urea (150 kg/ha), and LOF (Liquid Organic Fertilizer) (25 ml/L) ; (2) NPK (300 kg/ha) and Urea (150 kg/ha) fertilizer; and (3) LOF (25 ml/L). The subplots consisted of two rice varieties, Nutri Zinc and Inpari 32, so there were 6 treatment combinations repeated 4 times, resulting in a total of 24 units experimental . This study aimed to analyze the effect of fertilizer combinations on the growth and yield of Nutri Zinc and Inpari 32 varieties in rainfed fields. The results showed that the combination of fertilizers had significant effect on plant height and number of tillers. Inpari 32 variety was with superior higher plant height and more tillers than the Nutri Zinc variety. The combination of NPK, Urea, and LOF fertilizers with the Inpari 32 variety produced the highest productivity of 4.67 tons/ha, while Nutri zink variety with the same fertilizer is 4.41 tons/ha. The combination of NPK and Urea fertilizers with the Inpari 32 variety is 4.60 tons/ha and Nutri zink variety is 4.35 tons/ha. The use of LOF alone resulted in a lower number of tillers and productivity, 3.92 tons/ha for Inpari 32 variety and 3.66 tons/ha for Nutri Zink variet.

Abstract

Compost production in Indonesia is often hampered by conventional methods that rely on manual mixing, resulting in lengthy processing times, high labor requirements, and inconsistent compost quality. This study aimed to develop a mechanical compost mixer system featuring an innovative flow gate in a dual-brick-bin setup. The innovation is designed to improve mixing efficiency, mixture homogeneity, and energy consumption. The research was conducted in Tanjung Tebal Village, Lahat Regency, from March to June 2024, using materials such as household organic waste, animal manure, coffee husks, dry leaves, fresh leaves, and the EM4 bioactivator. The methodology investigated using a comparison of a 9HP gasoline engine and equipped with the innovative flow gate to manual methods. Parameters compared include mixing time, energy consumption, homogeneity distribution, and residual material. The results show the mechanical system reduced mixing time by up to 30% from an average of 45 minutes using manual methods to 30 minutes, mixture homogeneity increased to 95% compared to 70% with manual methods, while residual material decreased from 15% to 6%. The flow gate innovation in the dual-brick-bin system proved effective in enhancing the efficiency of the compost mixing process. Implementation of this technology has the potential to support organic waste management in rural areas, reduce environmental pollution, and promote sustainable agriculture. Further research is recommended to evaluate the system’s efficiency on a larger scale.
