Abstract

The objective of this community service activity is to provide knowledge and technology on the use of Probiotik Raja Siam in improving the growth and survival rate of Asia redtai catfish larvae in the Sawah Mandiri Fisheries Group, Sawah Village, Kampar Utara Subdistrict, Kampar Regency, Riau. The implementation methods included lectures, discussions, and hands-on field practice. Lectures and discussions were conducted in the group meeting room, covering the benefits of soaking asia redtai catfish larvae using Probiotik Raja Siam. Field practice was carried out at the hatchery, where participants were guided through the soaking process, distribution, and initial care of the larvae. The knowledge evaluation results showed a significant improvement in understanding. Out of the 13 group members present, 10 (76.92%) were able to absorb the material with an excellent rating, 2 (15.38%) with a good rating, and 1 (7.69%) with a satisfactory rating. The skill evaluation results showed that group members were able to apply the use of Raja Siam Probiotics to support the growth of asia redtai catfish larvae. Meanwhile, the impact evaluation results indicated that members of the Independent Rice Field Fisheries Group had begun using Raja Siam Probiotics to accelerate the growth of Asia redtai catfish larvae.

Abstract

The intensive use of chemical herbicides in agriculture has caused serious impacts on the environment, human health and ecosystem sustainability. These impacts include soil, water, and air pollution, as well as health risks due to exposure to hazardous active ingredients. As a solution, this study examines the potential of ketapang (Terminalia catappa L.) leaf extract as an environmentally friendly organic herbicide. The content of allelochemical compounds in ketapang leaves is proven to effectively inhibit weed growth, and is safer and more economical than synthetic herbicides. Thus, ketapang extract herbicide is considered to have high prospects as an alternative weed control that supports sustainable agriculture. This study aims to identify the optimal formulation and concentration of natural herbicides of ketapang leaf extract in suppressing weed growth, analysing the percentage of live, height, number of shoots, wet weight, and dry weight of weeds. The research was conducted at UNRI Gobah Campus and the author's house in Pekanbaru. The environmental aspects used 4 x 2 factorial RAL with 3 replications, factors of herbicide concentration (Gramoxone, ketapang extract 25%, 50%, 75%) and weed species (Cynodon dactylon L. and Cyperus rotundus). Data were analysed with variance analysis and 5% Duncan test. The results showed that the 75% concentration of ketapang leaf extract herbicide was effective in suppressing weed growth and could replace chemical herbicides still used by farmers, although the effect was not as fast as chemical herbicides in killing weeds. Especially on the percentage of live weeds, weed height, and weed species. The interaction between ketapang leaf extract herbicide and weed type was effective in suppressing weed growth but not on wet weight and dry weight of weeds. The use of ketapang leaf extract is more recommended because it can be used as an alternative to replace the use of chemical herbicides that are environmentally friendly and safe for health

Abstract

This study critically assesses regional development policies on Sumbawa Island, particularly the PIJAR program (Cattle, Corn, and Seaweed) and the corn nomenclature, through the perspectives of environmental ethics and critical theory. Employing a mixed-method approach, the research integrates a spatial analysis of land cover changes in the Padolo River Basin during 2017-2024 with a policy text examination based on Jürgen Habermas's theory of the "Colonization of the Lifeworld." The findings reveal that these policies reflect structural anthropocentrism, prioritizing economic production targets over ecological integrity in a top-down fashion. The consequence is a destructive transformation of the regional landscape, where the depletion of upstream forests triggers Policy-Induced Disaster phenomena, including increased frequency of floods and extreme droughts. The study concludes that the ecological crisis on Sumbawa Island is the result of a failed development vision that neglects the carrying capacity of nature and the government's inability to provide alternative employment opportunities for the community

Abstract

Pengembangan budidaya kelapa genjah melalui sistem agroforestry merupakan salah satu pendekatan strategis dalam mendukung pertanian berkelanjutan, diversifikasi usaha tani, dan peningkatan kesejahteraan masyarakat. Kegiatan ini bertujuan untuk meningkatkan pengetahuan dan pemahaman masyarakat mengenai teknik budidaya kelapa genjah berbasis agroforestry di Kepenghuluan Bangko Pusako, Kabupaten Rokan Hilir. Metode yang digunakan meliputi penyuluhan, demonstrasi lapangan, diskusi partisipatif, serta evaluasi melalui pre-test dan post-test untuk mengukur efektivitas transfer pengetahuan. Peserta kegiatan berjumlah 20 orang petani. Hasil evaluasi menunjukkan nilai rata-rata pre-test sebesar 52,50 meningkat menjadi 93,13 pada post-test, dengan nilai N-Gain sebesar 0,86 yang termasuk kategori tinggi. Hasil ini menunjukkan bahwa kegiatan penyuluhan efektif meningkatkan kapasitas pengetahuan peserta terkait budidaya kelapa genjah dan penerapan sistem agroforestry. Selain meningkatkan pemahaman teknis budidaya, kegiatan ini juga memperkenalkan manfaat agroforestry dalam optimalisasi lahan, diversifikasi pendapatan, konservasi lingkungan, dan penguatan ketahanan pertanian masyarakat. Introduksi budidaya kelapa genjah berbasis agroforestry berpotensi menjadi model pemberdayaan masyarakat menuju sistem pertanian berkelanjutan di wilayah pedesaan.
