Abstract

Ciujung Watershed is an important land located in Banten Province, Indonesia. The Upstream Ciujung Watershed has seen numerous changes in land usage. Before implementing the best watershed management practices, we must first gather knowledge about the watershed's features. This report seeks to provide information about the characteristics of the Upstream Ciujung Watershed, covering land-use changes, hydrological responses, and water balance. Land use changes were analyzed using satellite imagery from 2016 and 2021, with changes traced using ArcGIS and Excel; hydrological response method for flow regime coefficient (FRC) and annual flow coefficient (AFC) in the 2012−2016 and 2017−2021 periods. Water balance was analyzed by calculating water demand in 2021 and availability water from 2012−2021. The study found that deforestation occurred between 2016 and 2021. Primary forest, secondary forest, and production forest area fell by 51 ha, 1,073 ha, and 3,119 ha, respectively, while dryland agricultural area increased with a mix of shrubs, plantations, and settlements, contributing to the alteration in the watershed. The FRC and AFC values from 2012 to 2016 were 49 (poor) and 0.32 (moderate). Meanwhile, the FRC and AFC for 2017–2021 were 60 (moderate) and 0.30 (moderate). The water balance of the Upstream Ciujung Watershed in 2021 indicates a water surplus of 663,739,545 m3/year, while the dry season in September shows a shortfall of −5,468,643 m3/month. Keywords: annual flow coefficient, flow regime coefficient, hydrological function, watershed management

Abstract

Kegiatan ini bertujuan meningkatkan kapasitas masyarakat Desa Payakabung dalam mengelola limbah baglog jamur tiram dan kotoran sapi melalui produksi pupuk organik berbasis bioaktivator Trichoderma sp.. Pelatihan dilakukan dengan pendekatan partisipatif yang mencakup formulasi bahan, proses fermentasi, serta evaluasi mutu kompos. Analisis laboratorium digunakan untuk menilai parameter kimia utama dan membandingkannya dengan standar SNI 7763:2024. Hasil menunjukkan bahwa pH kompos sebesar 7,22 telah berada pada kisaran ideal dan menunjukkan stabilitas proses dekomposisi. Kandungan kalium total mencapai 4,03%, memenuhi persyaratan minimal hara makro dan memberikan manfaat agronomis bagi peningkatan ketahanan tanaman. Fosfor tersedia sebesar 70,36 ppm memberikan nilai tambah bagi kompos, didukung peran Trichoderma sp. dalam meningkatkan kelarutan fosfat. Namun, C-organik (3,10%) dan nitrogen total (0,00096%) masih berada di bawah standar sehingga menunjukkan bahwa rasio bahan dan durasi fermentasi perlu dioptimalkan. Meskipun belum memenuhi seluruh parameter mutu komersial, program ini berhasil mengurangi volume limbah organik dan menghasilkan kompos yang layak digunakan sebagai pembenah tanah. Perubahan perilaku masyarakat menuju pengolahan limbah secara mandiri menjadi indikator penting keberlanjutan program serta dasar untuk pengembangan produksi kompos yang lebih efektif pada tahap berikutnya.

Abstract

This Community Service Activity aims to improve the quality of rubber farmers' bokar in Lorok Village, Ogan Ilir, through effective tapping techniques, controlling white root fungus with Trichoderma sp, and using recommended coagulants. The implementation took place from September to December 2025 in Lorok Village, Ogan Ilir. The targets are for rubber farmers, rubber collectors, and Lorok Village officials. The activity began with a Forum Group Discussion and interviews to identify the problems of rubber farmers in Lorok Village, then preparing socialization materials, training and coaching designs, as well as pre- and post-activity evaluations; socialization, demonstrations, and mentoring; and analyzing Bokar results as an evaluation of the implementation of efforts to improve the quality of Bokar that were socialized. From the results of the activity, it was found that rubber farmers in Lorok Village can produce high-quality bokar if they apply effective tapping techniques, select recommended coagulants, and control JAP with Trichoderma sp. By carrying out this activity, farmers believe they will be able to increase their income by selling high-quality bokar at competitive selling prices for industrial needs.
