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

The provision of educational services in the Ha-Anim ecological region in Asmat Regency South Papua Province, faces various complex challenges, including limited resources, difficult geographical conditions and low community participation in supporting educational services. So far, community participation has tended to be passive and symbolic, thus failing to make a real contribution to improving the quality and sustainability of education. Based on these conditions, this study aims to examine a relevant community participation transformation model to strengthen the governance of education services based on local wisdom, inclusiveness and sustainability. This study uses a descriptive qualitative approach with purposive sampling techniques to determine informants from two districts in Asmat Regency, namely Agats District (urban area) and Ayam District (rural area). The informants consisted of local stakeholders representing the 3-Tungku elements (traditional leaders, religious leaders and village government) and the 2-Peran elements (female leaders and youth leaders). Data collection was conducted through in-depth interviews and Focus Group Discussions (FGD), while data analysis consisted of three main stages, namely: (1) identification of primary and secondary data, (2) categorization of data according to research themes, and (3) interpretation and analysis of results based on qualitative research principles. The results of the study show that the transformation of community participation in Asmat needs to be directed towards a paradigm shift from formal participation to substantive participation. Revitalizing school committees is a key strategy through the integration of local social elements, namely traditional leaders, religious leaders, women and youth as representatives of the community.
