Abstract

Pengendalian hama lalat buah dengan Perangkap Metyl Eugenol dilaksanakan di kampung Wambena, Distrik Depapre, Kabupaten Jayapura. Kegiatan tersebut dilatarbelakangi oleh masalah gagal panen dan pembusukan buah-buahan seperti pada bauh mangga, akibat serangan lalat buah milik petani. Kegiatan Pengabdian ini di mulai dengan sosialisi tentang lalat buah kepada Masyarakat, kemudian dilanjutkan dengan pembuatan dan pemasangan perangkap lalat buah dengan metyl eugenol. Peserta sangat antusias mengikuti kegiatan karena alat dan bahan yang diperlukan untuk pembuatan perangkap mudah didapat dan murah. Juga pembuatan perangkap sangat mudah dan cepat serta ramah lingkungan. Setelah sebulan dilakukan monitong pengecekan perangkap lalat buah dan menunjukan hasil yang cukup memuaskan karena banyaknya lalat buah jantan yang terperangkap dan berhasil menurunkan populasi lalat buah di Kampung Wambena.

Abstract

Local cocoa offers substantial value-addition opportunities for women-led microenterprises, yet gaps in processing skills, basic business practices, and market access constrain outcomes. This community service program empowered a women’s fellowship through structured, participatory training on cocoa-based product development. Objectives were to strengthen technical competencies for two ready-to-consume products (chocolate drink and chocolate jam), introduce basic business management (cash records, cost of goods sold/COGS, pricing), and build entry-level digital marketing and branding skills. Methods combined a community-based participatory approach (coordination, needs assessment, material preparation) with sequential sessions orientation, lecture discussion, hands-on practice, reflection and mixed-method evaluation (pre/post Likert survey and rubric-based observation). Ten participants completed the training. Results show participants replicated both products with more consistent quality, applied hygienic handling (heating/sterilization), and prepared simple business documents (cash ledger, COGS). Foundational brand assets (product name, basic label, initial promotional content) supported early commercialization, while collaborative work routines and peer champions emerged to sustain production. In conclusion, the intervention effectively enhanced technical, managerial, and promotional readiness and offers a practical model for community-based microenterprises that add value to local cocoa resources.

Abstract

Aquaculture of common carp (Cyprinus carpio) is a freshwater fishery commodity with high economic value and requires well-controlled water quality and fish health management. However, small- to medium-scale farmers still face limitations in continuous water quality monitoring. This community service activity aimed to improve the capacity of common carp farmers at Unit Pengolahan Air Dunia Air through training and mentoring on water quality and fish health management based on simple technology. The activity was conducted from September to October 2025 at Unit Pembenihan Rakyat Dunia Air, Koya Timur, Jayapura City. The methods employed included training sessions, discussions, hands-on practice mentoring, and the application of technology in the form of an Internet of Things (IoT)-based water quality monitoring device and a water quality control logbook. The IoT device was used to monitor water quality parameters in real time, while the logbook functioned as a tool for routine recording and evaluation. The results showed an increase in participants’ understanding of water quality management concepts, as indicated by their ability to identify key water quality parameters along with their optimal ranges. In addition, participants demonstrated improved skills in operating IoT-based monitoring devices and in routinely recording data in the water quality control logbook. Changes in aquaculture practices were also observed, including increased frequency of water quality monitoring and the implementation of fish disease prevention measures. The application of this technology promotes more controlled and sustainable common carp aquaculture practices.

Abstract

Artisanal mining activities are recognized as important sources of heavy metal contamination in river ecosystems. This study evaluated cadmium (Cd), lead (Pb), and mercury (Hg) concentrations in water and sediments of Kali Jembatan Dua, Jayapura, Papua, Indonesia, as baseline information for environmental monitoring. Water and sediment samples were collected from three stations representing upstream mining areas and downstream river sections in June 2025. Heavy metal concentrations were analyzed using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Concentrations in water ranged from 0.076-0.313 mg/L for Cd, 0.0032-0.0076 mg/L for Pb, and 0.0014-0.0039 mg/L for Hg. Cadmium exceeded the applicable Indonesian water quality standard, whereas Pb and Hg concentrations varied according to the designated water-use classification. Sediment concentrations ranged from 0.347-0.894 mg/kg (Cd), 0.721-2.234 mg/kg (Pb), and 0.0165-0.0277 mg/kg (Hg). Metal concentrations were generally higher at stations near mining activities and lower downstream. Sediments contained higher metal concentrations than the water column, indicating their role as sinks and potential secondary sources of contamination. These findings highlight the need for continuous monitoring and management of mining-affected river systems in Papua.
