Abstract

Porang (Amorphophallus muelleri) is a tuber plant that contains the compound of glucomannan which has high economic value with a number of benefits, including as an industrial raw material. The glucomannan content of porang tubers has received special attention in research, including field research to determine soil properties that influence growth and content of gucomannan in porang tubers. A field survey has been carried out to determine the physical properties of soils that influence the glucomannan content of porang tubers grown in four clusters of agroforestry in the dry land of North Lombok, Eastern Indonesia. The results of the research showed that the physical properties of the soil that had a significant effect on the glucomannan content of porang tubers were soil bulk density (BD) with an R2 value of 53.15%, soil porosity with an R2 value of 60.23%, and silt particle fraction with an R2 value of 23. 47%. Thus, managing soil physical properties to facilitate the better quality of porang tubers is necessary.

Abstract

This service aims to increase the knowledge and skills of Patuh Bersama farmer group members in processing rice husk Biochar agricultural waste using the Retort Kiln method. The method of implementing this service activity used a technical guidance method with a participatory approach. Evaluation of this activity was carried out through interactive sharing and then the data was analyzed descriptively. The results of this service activity showed that the farmer group could understand and had the skills to make rice husk biochar using the Retort Kiln method. Apart from that, from the results of this service it is hoped that farmers can utilize agricultural waste as a soil improvement material on agricultural land.

Abstract

Gili Air is part of a group of small islands without waste problems. Efforts to reduce and manage waste in Gili Air, Gili Indah Village, still need to be improved, considering that the potential for waste generation is still significant, especially organic waste, which is 55% of the total potential for waste generation. The potential for recycling waste on Gili Air shows a waste-carrying capacity index value of 0.20, which means it is lower than the generation potential. It impacts Gili Air's relatively low level of waste support. As a tourist destination, Gili Air produces solid waste from local communities and tourism activities. This community service activity aims to increase awareness of the community and business owners in the tourism sector in Gili Air to reduce the rate of daily waste generation by reducing and utilizing organic waste to be processed into solid or liquid compost. The method applied for community service on Gili Air is in the form of outreach and training, demonstrating the stages of composting using a simple process that is easy for local communities to implement. Based on the results of monitoring and evaluation of community service activities, there was an increase in understanding of community service participants. It is indicated by a decrease in the percentage of wrong answers from the questionnaire announced after the service activity (post-test). In the pre-test before receiving community service, it was discovered that 59% of people still answered the statement on the questionnaire wrong. However, wrong answers decreased to only 12% after socialization and training. Increasing understanding of the pre-and post-test statements shows that socialization and training can positively impact community empowerment in managing household waste into solid and liquid fertilizer.

Abstract

Tanah vertisol yang memiliki sifat fisik dan kimia bermasalah memerlukan strategi ameliorasi untuk mendukung pertanian berkelanjutan. Penelitian ini bertujuan mengevaluasi pengaruh aplikasi biochar sekam padi dan mulsa organik terhadap sifat kimia dan fisik tanah vertisol serta produksi kacang hijau (Vigna radiata L.). Penelitian dilakukan selama enam bulan (Januari–Juni 2024) di lahan tadah hujan Desa Segala Anyar, Lombok Tengah, menggunakan Rancangan Acak Kelompok faktorial dua faktor: dosis biochar (0, 10, dan 20 ton/ha) dan jenis mulsa (plastik dan jerami padi 5 ton/ha), masing-masing dengan empat ulangan. Parameter yang diamati meliputi C-organik, pH, nilai COLE, kapasitas air tersedia (KAT), dan berat 100 biji kacang hijau. Hasil menunjukkan bahwa kombinasi biochar 20 ton/ha dan mulsa jerami secara signifikan meningkatkan C-organik (1,49%), menaikkan pH (6,85), menurunkan nilai COLE (0,13), serta mempertahankan KAT di atas 10%. Kombinasi tersebut juga menghasilkan berat 100 biji tertinggi (1,40 ton/ha), mengindikasikan peningkatan efisiensi fisiologis tanaman. Temuan ini mengonfirmasi bahwa integrasi biochar dan mulsa organik efektif memperbaiki kualitas tanah marginal dan meningkatkan hasil tanaman, mendukung praktik pertanian berkelanjutan.
