Abstract

Local knowlede is a phenomenon that is felt and experienced by the people of a particular area who have local understanding regarding the natural resources found in the surrounding environment. One of this knowledge is about long-tailed macaque (Macaca fascicularis). This research aims to examine local knowledge of the community regarding long-tailed macaque in Mekarwangi Village which borders Taman Hutan Raya Ir. H. Djuanda which is one of the long-tailed macaque conservation sites. The method used in this research is a qualitative approach through observation, semi-structured interviews, and strengthened by literature study. The result obtained were analyzed descriptively. The reseach result show that the community knows about the existence of long-tailed macaque. Community interactions with long-tailed macaque pose a threat to long-tailed macaque, some individu of long-tailed macaque be arrasted because people are disturbed by their existance. The majority of community in Mekarwangi Viilage know the food, habitat, and daily activities of long-tailed macaque from daily observation and some knowledge passed down from previous generations.

Abstract

Eco-enzymes are a natural alternative to harmful synthetic chemicals in the home. Changing organic kitchen waste from vegetable and fruit waste into household and environmental recycling materials can help solve the waste problem. Eco-enzyme liquid has many uses, such as washing dishes, clothes, floors, hair, body wash, hand sanitizer, body detox, air freshener, radiation blocker, pool cleaner, pet and organic fertilizers and pesticides that can be made from organic waste. This community service program aimed to increase public awareness and sensitivity to the problems that were found in the environment, provide ideas for entrepreneurship such as the utilization of waste in the form of eco enzymes, and eco brick. The socialization activities were carried out through presentations, discussions, and demonstrations of making eco enzymes, as well as distributing questionnaires to find out the increase in the level of public understanding before and after the activity was carried out. The questionnaire results showed that people's knowledge about the use of organic waste to make eco enzymes increased after participating in extension activities, as well as the community's interest in processing organic waste into eco enzymes and using them in daily life

Abstract

Cibunut is a densely populated urban area at the center of Bandung City, West Java. This village has been chosen by the district government as a pro-climate area, but this policy was little known to children. This socialization aimed to provide knowledge and foster pro-environmental behavior in children as early as possible so that the values that the children obtained were internalized independently and would have an impact on a sustainable lifestyle after adulthood as a form of mitigation against climate change. This socialization activity used the creative educational approach, namely insight, role models, and conditioning. The results of this activity not only provided knowledge about the impact of supporting cleanliness but also increased the children's motivation to take part in environmental love activities. During the socialization, children were challenged to practice environmentally friendly behavior together. This enjoyable education approach in community service was able to foster children who care about environmental issues can be seen from their awareness of the environment and climate change, ready to contribute toward keeping a clean and sustainable environment.

Abstract

This study aimed to assess the ability of water hyacinth (Eichhornia crassipes) as a bioaccumulator of heavy metals copper (Cu) and zinc (Zn) in rubber industry wastewater at PT Batanghari, Bengkulu. The research methods included water and water hyacinth sampling from effluent ponds and controls, followed by analysis of Cu and Zn levels using atomic absorption spectrophotometry (AAS). Results showed that Zn levels in wastewater reached 143.0884 mg/l (28 times the quality standard), while Cu was 0.1845 mg/l (still below the quality standard). Water hyacinth accumulated metals in different patterns: Cu was highest in the roots (1.4480 mg/l), while Zn was evenly distributed in the roots (6.7261 mg/l) and leaves (6.6473 mg/l). Analysis of bioaccumulation (BAF) and translocation factors (TF) revealed the efficiency of water hyacinth in absorbing metals, especially Zn, although the absorption mechanism is selective and influenced by environmental conditions such as pH, dissolved oxygen, and the presence of organic compounds. The implications of this study emphasize the potential of water hyacinth as an economical and sustainable phytoremediation solution for the rubber industry, with recommendations of implementing a constructed wetland system and periodic harvesting for optimization.
