Abstract

Smoked fish products produced by fishing households in Jayapura City are widely known, becoming food products that are popular with city residents and souvenirs for tourists. The development of this superior commodity requires at least four requirements, namely that commodity procurement must be continuous in quantity, quality and at the right time, have good traceability, continuous development and mastery of technology, and adequate mastery of business management. It is within this framework that this community service activity is carried out. The aim of this Community Partnership Service activity is to empower the community to increase their knowledge and skills in using appropriate fish smoking equipment, making hygienic packaging, understanding production and marketing management and making simple cash books in running a smoked fish processing business in Hamadi Village, Jayapura City. This service uses participatory rural appraisal methods, fisheries education, and pretest posttest control group design. Based on the results of the implementation of activities with POKLAHSAR Mama Papua partners on 26-27 August and 22-23 September 2023, it is known that there is an understanding of cash bookkeeping, the use of appropriate smoking equipment, production management and marketing management, as well as making hygienic packaging for smoked tuna. , has increased. It is hoped that this can become a benchmark for the development of the smoked fish business among partners as targeted in the activity objectives.

Abstract

Microalgae such as Chlorella sp. are valuable for their potential in sustainable food, feed, and bioenergy production, but their cultivation often relies on costly synthetic nutrients. Exploring alternative nutrient sources, such as liquid organic fertilizers, may offer a more economical and environmentally friendly approach to biomass production. This study aims to evaluate the effect of liquid organic fertilizer application on the growth of Chlorella sp. in a closed culture system. Seven treatments were used: one control without fertilizer (K) and six treatments with increasing fertilizer doses (P1–P6). The observed parameters included initial and final cell density, as well as daily growth rate during a seven-day incubation period. The results showed that fertilizer application had a significant effect on the growth enhancement of Chlorella sp. The highest final cell density was recorded in treatment P6, exceeding 6.3 × 10⁷ cells/ml, while a population decline was observed in the control group. The daily growth rate also increased with higher fertilizer doses, with the highest value (μ = 0.36) observed in P6. Linear regression analysis showed a strong relationship between fertilizer amount and growth rate (r = 0.8493; p = 0.0156; R² = 0.7213), indicating that growth variation could be significantly explained by the amount of fertilizer applied. The conclusion of this study is that liquid organic fertilizer has great potential as an efficient and environmentally friendly alternative for microalgae culture media. Proper dosage formulation can support optimal microalgal biomass production. Further research is needed to identify the dominant nutrient content in the fertilizer and to assess the biomass quality for potential applications in food, feed, or bioenergy sectors.

Abstract

Danau Sentani merupakan sumber air, pangan, perikanan, dan ruang hidup masyarakat Kampung Ayapo. Keterbatasan literasi sains anak dan sarana praktik di Rumah Baca menyebabkan pembelajaran kualitas air belum berlangsung secara kontekstual. Kegiatan ini bertujuan meningkatkan pemahaman dasar kualitas air, memperkenalkan praktik penyaringan air sederhana, dan mengenalkan peralatan laboratorium melalui konsep lab keliling. Kegiatan dilaksanakan pada 4 Juli 2026 di Rumah Baca Kampung Ayapo dengan pendekatan pendidikan masyarakat, praktik langsung, demonstrasi, serta evaluasi pre-test dan post-test. Sebanyak 43 peserta dibagi menjadi empat kelompok berdasarkan rentang usia dan jenjang pendidikan, kemudian mengikuti rotasi pada Pos Asam-Basa, Pos Kekeruhan, Pos Cuci Tangan, dan Pos Laboratorium. Hasil evaluasi menunjukkan proporsi peserta yang menjawab pertanyaan dengan benar meningkat dari 41,86% pada pre-test menjadi 86,05% pada post-test, atau naik 44,19 poin persentase. Kegiatan menunjukkan bahwa eksperimen sederhana dan pengalaman langsung berpotensi mendukung penguatan literasi sains dan kesadaran lingkungan.
