Abstract

Aquatic productivity is the most basic trophic level in every aquatic ecosystem. Lake Dringo is a protected area and one of the highest lakes on the island of Java. Ecosystem balance can be seen from the study of water productivity. The purpose of this study was to determine the primary productivity and secondary productivity of waters in the Lake Dringo Nature Reserve, Central Java. The purposive sampling method was used in this study by establishing five stations and three replications at each station. The combination of primary and secondary productivity has a total abundance of 22,491-38,556 ind/liter. The highest abundance was Chlorophyta at 33% while the lowest abundance was Rotifera at 4%. This shows that there is no species dominance so that the primary productivity of the waters is still good.

Abstract

The distribution of benzalkonium chloride (BAC) in inland waters has not been widely studied, despite its known dangerous effects on organisms. This study was conducted to determine the concentration of BAC in the Donan River, Cilacap, which receives significant input from domestic waste, particularly from the food industry. The study employed a quantitative descriptive method to analyze the presence of BAC in the river, with sampling stations selected using the purposive sampling method to ensure comprehensive coverage. Samples were collected from five different stations along the Donan River, revealing BAC concentrations at station 1 ranging from 0.128 to 0.140 µg/l, station 2 from 0.213 to 0.237 µg/l, station 3 from 0.163 to 0.190 µg/l, station 4 from 0.176 to 0.210 µg/l, and station 5 from 0.240 to 0.247 µg/l. These findings indicate that the concentration of BAC in the Donan River is comparable to levels found in other rivers worldwide, where the presence of BAC has been documented. The study highlights the need for regular monitoring of BAC levels in inland waters, given its potential ecological impacts. The elevated levels of BAC, especially in areas receiving substantial domestic waste, suggest that the discharge from the food industry and other domestic sources significantly contributes to the contamination.  Keywords: domestic waste, ecology, micro pollutants, toxicology, water pollution.

Abstract

The waste problem in Indonesia is becoming increasingly complex in line with the growth of the population and public consumption. The circular economy approach offers a sustainable alternative solution based on the principles of reducing, reusing, and recycling waste to maintain its economic value. This study examines a local, community-based innovation known as KRASA BUNGAH as a waste management model that integrates the concept of a circular economy. Waste management innovation that provides direct benefits to the community can serve as a solution by addressing waste at its source. The aim of this research is to evaluate the effectiveness of KRASA BUNGAH in supporting sustainable waste management. This study employs a descriptive method. The research sites were purposively selected in three locations. The study was conducted over eight months, with data collection carried out monthly. The results show that KRASA BUNGAH can serve as an innovative waste management model that promotes community self-reliance and is based on the principles of the circular economy.
