Abstract

This study aims to analyze water quality and heavy metal lead (Pb) content in the waters of Class II Port of Jayapura, Papua. Increased port and industrial activities in coastal areas can contribute to environmental pollution, including heavy metal contamination that impacts marine ecosystems and the health of coastal communities. This research employed a descriptive method with water sampling at 2 stations, each consisting of 3 sub-stations using purposive sampling technique. Seawater samples were analyzed at the Chemistry Education Laboratory of Cenderawasih University using Atomic Absorption Spectrophotometry (AAS). Water quality parameters measured included temperature, pH, Dissolved Oxygen (DO), transparency, and salinity. The results showed that water quality parameters were within safe ranges according to quality standards, with temperature ranging from 30.2-32.5°C, pH 6.54-7.60, DO 5.45-8.55 mg/l, transparency 3.20-3.57 meters, and salinity 30-34. However, the heavy metal lead (Pb) content in seawater ranged from 0.115-0.141 mg/l, which exceeded the established quality standard limit of 0.05 mg/l based on Government Regulation Number 22 of 2021 and Minister of Environment Decree Number 51 of 2004. This research indicates that port activities such as loading and unloading of goods, ship washing, fuel usage, fuel spillage, and use of ship coating paint can affect the level of lead in the waters. Special attention and strict supervision of port activities are required to minimize heavy metal pollution in the waters of Jayapura Port.

Abstract

Louhan fish are predatory fish from Lake Sentani that can be processed into fishery products such as nuggets. Nuggets are created from a mixture of crushed fish meat, flour, and other ingredients, then coated with flour. This initiative aims to enhance the skills of partners in processing louhan fish into nugget products. The partners in this community service activity are mothers at the Al-Manshurin Islamic Boarding School in Waena, who lack creativity in processing louhan fish into various products. The challenge faced by the partners is a lack of knowledge regarding the louhan fish processing. Therefore, the solution provided is training in making louhan fish nuggets. The community service activity was conducted at the Al-Manshurin Islamic Boarding School, located in Waena, Jayapura City. The methods employed were socialization, practice, and evaluation. Twenty participants attended this community service activity. The participatory role of partners in this activity is to be actively involved in all stages, from socialization and practice to evaluation. The community service activities conducted by the team demonstrated a 100% increase in the skills of all mothers at the Al-Manshurin Waena Islamic Boarding School in making louhan fish nuggets after the processing practice.
