Abstract

Diversifikasi Olahan Ikan merupakan motivasi baru untuk memperkenalkan kepada masyarakat bahwa ikan yang biasanya dikonsumsi dalam bentuk digoreng, dibakar atau dimasak dalam keadaan utuh dapat dibuat makanan yang lebih menarik dan tetap bergizi yang dapat dikonsumsi mulai dari anak-anak, dewasa, sampai usia lanjut. Beberapa produk diversifikasi hasil perikanan antara lain: bakso ikan, nugget ikan, abon ikan, dan sosis ikan. Kampung Tablasupa Terletak di Distrik Depapre Kabupaten Jayapura, Provinsi Papua. Kampung Tablasupa termasuk kampung yang cukup berkembang di Kabupaten Jayapura dibandingkan dengan kampung-kampung lain. Kampung Tablasupa memiliki Industri Rumah Tangga Pangan (IRTP) yang di kerjakan oleh ibu-ibu dalam kelompok usaha. Usaha yang di jalankan adalah usaha diversifikasi produk ikan seperti nugget ikan. Usaha ini sudah di kembangkan sejak kurang lebih dua tahun. Dalam menjalankan produksi kelompok ibu-ibu IRTP Kampung Tablasupa masih menggunakan sarana prasana sederhana. Hal ini dapat memberikan dampak bagi kesehatan dan lingkungan. Tujuan dilakukan penelitian ini adalah untuk mengetahui Sanitasi dan Hygiene pada Pengolahan Nugget Ikan Industri Rumah Tangga (IRT) di Kampung Tablasupa Distrik Depapre, Kabupaten Jayapura, Papua. Data diperoleh dari hasil wawancara terhadap ibu-ibu pelaku usaha menggunakan angket dan pengamatan langsung proses pembuatan nugget ikan. Hasil penelitian menunjukkan bahwa usaha nugget ikan ini masih dalam skala industri rumah tangga yang pengolahannya dilakukan sendiri oleh ibu-ibu dalam kelompok usaha. Industri ini masih sederhana dan pengolahan nugget ikan yang dilakukan masih belum memenuhi standar karena tidak di dukung dengan sarana prasarana yang baik, seperti lokasi dan lingkungan yang sesuai, gedung yang permanen, ketersedian air bersih yang cukup, dan kesehatan para karyawan. Sehingga usaha yang dilakukan ini belum memenuhi standar sanitasi dan higiene baik dari segi sarana prasarana dan karyawan atau pekerja.

Abstract

The purpose of this study was to assess the microbiological quality of smoked fish at the processing center in Jayapura City, Papua. 100 kilograms of smoked fish were tested, samples were taken from producers, distributors, and retailers at three distribution levels. Microbiological tests included identification of Salmonella sp. bacteria and Total Plate Count (TPS) tests. The results of the study were conducted using ANOVA and DMRT further tests at a significance level of 95%. The average TPS value at all distribution levels ranged between 3.379 and 3.509 log cfu/g, which is still within the safe limit for consumption (p>0.05). Each sample tested did not show any Salmonella sp. contamination. This study shows that smoked fish products in Jayapura City are microbiologically safe, but care during distribution needs to be improved, especially in terms of packaging and cleanliness, so that the product continues to satisfy consumers. Consumers can be more satisfied and shelf life can be extended with better hygiene, packaging, and better distribution chain management. The results of this study provide important insights for producers, consumers, and related parties about the quality of Jayapura smoked fish. This information can be used as a basis for fisheries policy and product quality improvement.

Abstract

Papua island has the largest mangrove forest area in Indonesia, reaching 1,350,600.00 Ha which accounts for half of the entire area of mangrove forests in Indonesia. One of the locations with a fairly extensive mangrove forest in the Jayapura area is in Youtefa Bay. Although mangroves have large environmental potential, local people use the forest as building materials, food, fishing tools, and medicines. Mangrove forests have an active role in maintaining global climate stability in the world, forest vegetation will fix CO2 through the process of photosynthesis. Mangrove forests per hectare can store up to four times more carbon than other tropical forests worldwide. This research aims to estimate the amount of carbon stock Rhizophora mucronata can store in mangrove forests in Youtefa Bay, particulary in Tobati, Enggros and Entrop Villages, Jayapura, Papua. The method used in this study was using Allometric Equations to estimate the biomass carbon from Rhizophora mucronata and compared to three different satellite imagery algorithms. The research results showed that the biomass of Rhizophora mucronata stands in Entrop Village was the highest and the lowest in Enggros Village. In addition, the results of measurements of carbon stocks in Tobati and Enggros Villages showed that the values were similar, only 0.23 kgC/m2 with carbon stocks in Entrop Village reaching 19.46 kgC/m2. Based on the results of measuring satellite imagery with three different algorithms, it was found that using the EVI algorithm produced the smallest Standard Error of Estimate, which was 1.63 kg C/m2. The estimated total carbon in Youtefa Bay is 213,424.69 kg C/m2.Keywords:AllometricCarbon StockRhizophora mucronataYoutefa Bay

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.
