Abstract

Increased activity in the Badung river basin has an impact on water quality, including river estuaries and the sea, which will affect the environmental ecosystem. One of the water and sediment pollutants is heavy metals. Heavy metal pollution can be overcome with phytoremediation. This research aims to analyze the ability of the Rhizophora apiculata and Sonneratia alba mangroves to accumulate the heavy metals Pb and Cu.  Phytoremediation naturally occurs at river estuaries, namely in mangrove plants. Metal absorption in mangroves occurs in the roots which are then carried to the leaves. The research was conducted at the mouth of the Badung River, Denpasar, Bali. The research results show that the Pb metal content in water has exceeded the quality standards for marine tourism and marine biota based on PPRI No. 22 of 2021, namely an average of 0.005 mg/l. Metal absorption occurs in two types of mangroves, namely Rhizophora apiculata and Sonneratia alba. The highest metal absorption in mangroves is the Sonneratia alba species. Mangroves translocate metals from roots to leaves. From the research results, mangroves are classified as low accumulator plans.

Abstract

Turmeric (Curcuma longa L.) is a rhizome crop with high economic value and is widely used in traditional medicine, functional foods, cosmetics, and herbal beverages. Farmers in Ramadana Village face challenges related to limited knowledge in selecting quality seed rhizomes and applying appropriate cultivation techniques. This community service program aimed to improve farmers' knowledge and skills regarding quality turmeric seed selection and proper planting techniques. The methods used included socialization, counseling, field demonstrations, technical training, and mentoring activities. The program was conducted using a participatory approach involving farmers as active participants. The results indicated an improvement in farmers’ understanding of quality seed criteria, land preparation, planting distance, and crop maintenance practices. Farmers were also able to independently select quality seed rhizomes and apply recommended cultivation techniques. This program positively contributed to increasing farmers’ capacity and served as an initial step toward improving turmeric productivity and economic value in Ramadana Village.
