Abstract

Soil respiration is an indicator of the level of soil health in both closed systems (forests) and open systems (agriculture). Conversion of land from natural forest to agricultural cultivation needs attention in the field of sustainability, this is done so that the land can continue to be productive. This research aims to obtain information regarding the relationship between respiration and soil properties in land cover of oil palm (Elaeis guineensis), teak (Tectona grandis), and burflower-tree (Neolamarckia cadamba) in INSTIPER's experimental plantation, specifically in SEAT (Stiper Edu Agro Tourism) Ungaran Regency, Central Java. The method used in this research is a modified Verstraete, namely by observing soil respiration directly on the land. Research data shows respiration rates of 100.1, 95.4, and 25.9 mg CO2 m-2 h-1 for oil palm, burflower-tree, and teak respectively. Soil respiration is influenced by land cover in vegetation. Differences in land cover cause differences in soil properties which then influence the rate of soil respiration. The relationship between soil respiration rate and moisture content, pH, and EC is linear positive, while with volume weight it is linear negative.

Abstract

This study aims to identify and analyse the diversity of insect visitors to the cayenne pepper (Capsicum frutescens) garden in the karst area of Gunung Kidul, Yogyakarta. The method used was purposive sampling method by direct capture. The data collected were analysed by Shannon-Wiener diversity index. The conclusion of this study is that there is a diversity of visitor insects categorised as medium (H'=1.7) in the cayenne pepper garden in the karst area of Gunung Kidul, Yogyakarta. This insect diversity can help in the process of pollination and natural pest control in cayenne pepper plants in the karst area. Understanding the diversity of these insects is important for environmental conservation and sustainable agricultural management, especially in karst areas.

Abstract

The karst landscape in Gunungkidul Regency faces major challenges in the agricultural sector, mainly due to limited water availability and dependence on rainfed farming systems. To overcome these challenges, a community service program was implemented by introducing rainwater harvesting and drip irrigation technology to the Giri Muda Farmer Group. This activity aims to increase water availability and water use efficiency in drylands through the application of environmentally friendly technology. The community service method includes an initial survey, system design planning, installation of rainwater harvesting and drip irrigation installations, and technical training for farmers on system operation and maintenance. The evaluation of the activities showed a significant increase in understanding and skills, which had a positive impact on horticultural agricultural productivity. The technology was well received by farmers and has great potential to be developed in the Gunungkidul region and other similar areas. This service program not only succeeded in increasing agricultural productivity in drylands but also contributed to mitigating the impacts of climate change.

Abstract

Lanskap karst seperti di Gunungkidul, Yogyakarta, menghadapi tantangan serius dalam sektor pertanian akibat kelangkaan air dan kondisi tanah yang dangkal serta mudah tererosi. Keterbatasan ini menghambat produktivitas pertanian dan ketahanan terhadap variabilitas iklim. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pertanian berkelanjutan yang secara khusus disesuaikan dengan karakteristik wilayah karst. Sistem yang dikembangkan mengintegrasikan pemanenan air hujan, ekstraksi air tanah yang terkendali, akuakultur, dan irigasi tetes. Penerapan dilakukan di Desa Sumbergiri, Gunungkidul. Air hujan dikumpulkan dari atap bangunan dan disimpan untuk digunakan saat musim kemarau, sehingga mengurangi ketergantungan pada air tanah. Air tanah diambil melalui sumur dalam dengan pompa bertenaga surya sebagai sumber cadangan. Limbah akuakultur yang kaya nutrisi dimanfaatkan untuk mengairi tanaman melalui sistem irigasi tetes yang menyalurkan air langsung ke zona akar tanaman secara efisien. Hasil penelitian menunjukkan bahwa pendekatan terintegrasi ini meningkatkan efisiensi penggunaan air, mendukung daur ulang nutrisi, dan meningkatkan hasil panen, bahkan selama musim kemarau. Sistem ini menawarkan model yang dapat direplikasi untuk pertanian berkelanjutan di wilayah karst dan daerah yang kekurangan air.

Abstract

Pengelolaan limbah organik, khususnya daun bambu, menjadi isu penting dalam pelestarian lingkungan dan pertanian berkelanjutan. Di Indonesia, sekitar 40% sampah terdiri atas limbah organik, namun pemanfaatannya masih rendah, termasuk pada daun bambu yang sering dibakar, meningkatkan emisi karbon. Padahal, daun bambu memiliki rasio C/N yang ideal untuk kompos, mudah terurai, dan dapat memperbaiki kualitas tanah. Salah satu tantangan utama dalam pemanfaatan daun bambu adalah rendahnya pengetahuan masyarakat tentang pengelolaan limbah organik ini. Untuk itu, program pengabdian kepada masyarakat ini dilaksanakan di KTH (Kelompok Tani Hutan) Bambu Lestari Bulaksalak, Desa Wukirsari, Kapanewon Cangkringan, Kabupaten Sleman, dengan pendekatan partisipatif. Program dimulai dengan sosialisasi melalui presentasi dan diskusi mengenai pengelolaan limbah organik, manfaat kompos, serta potensi daun bambu sebagai bahan kompos. Sosialisasi ini bertujuan untuk meningkatkan pemahaman warga dan mendorong adopsi praktik ramah lingkungan. Setelah itu, kegiatan dilanjutkan dengan praktik langsung pengomposan di lahan milik pemerintah desa. Proses pengomposan terdiri atas tujuh tahap: pengumpulan dan pembersihan seresah bambu, pencacahan daun bambu, pencampuran bahan kompos (daun bambu, pupuk kandang, dan tanah), pengaturan kelembapan, pengadukan awal, serta pemeliharaan tumpukan kompos selama proses fermentasi. Setelah sekitar 40 hari, kompos matang siap digunakan sebagai pupuk organik. Program ini berhasil meningkatkan keterampilan teknis warga dalam pengelolaan limbah organik dan memperkuat kesadaran tentang pentingnya pemilihan lokasi pengomposan yang tepat. Untuk keberlanjutan, pendampingan lebih lanjut dan penguatan kelembagaan lokal sangat dibutuhkan, selain kolaborasi lintas sektor untuk mereplikasi model ini di wilayah lain.

Abstract

Palm Oil Mill Effluent/POME is a by-product produced from the processing of fresh fruit bunches/FFB into crude palm oil/CPO. Aeration of POME is one of the processing methods that aims to reduce the levels of organic matter and pollutants. This study aims to determine the dynamics of POME pH with aeration treatment and dilution variations in order to speed up the waste treatment time.The method used in this research is to make the treatment of pure POME, POME & water in a ratio of 1:1 & 1:2. The process carried out in the study was to place the solution into a 1 liter bottle and given an air flow using an aerator with a discharge of 0.66 l/min. POME samples were taken every 24 hours for a span of 7 days. The pH was measured using the electrometric method. On day 2, it was found that the pH of the 1:1 treatment POME had reached pH 6, while the 1:2 treatment on day 3 and the pure POME only reached pH 6 on day 5. Aeration is an effective method to neutralize the acidity of POME. The increase in POME pH was fastest in the 1:2, 1:1 and finally pure POME dilutions. All treatments met the pH quality standard on day 5. Aeration can help improve the quality of POME so that it is more environmentally friendly.

Abstract

Oil palm plants are commodities that are mostly processed to produce CPO (Crude Palm Oil) and PKO (Palm Kernel Oil), processing plants also produce waste (by product). The highest waste produced is liquid waste (POME) around 65% and empty palm bunches around 23%. In an effort to reduce environmental pollution, the company is committed to implementing zero waste by reusing palm oil mill waste as organic fertilizer. Research with the aim to determine the effect of the application of palm oil mill effluent, empty fruit bunches, and non-application (inorganic fertilizer) was conducted at the Sungai Rungau Estate (SRGE) plantation, PT Binasawit Abadi Pratama, East Kotawaringin Regency, Central Kalimantan, from November 2023 - April 2024. The research used a survey method to describe the research site and collect primary and secondary data, with each application consisting of 3 blocks. Production data and agronomic characters obtained were then analyzed using t test at 5% level. The results revealed that the application of POME resulted in higher agronomic and production characteristics than tankos. Oil palm production in blocks applied with POME and inorganic fertilizers showed values that were not significantly different and higher than tankos application blocks, and POME application showed productivity that tended to be stable every year.
