Water as a natural resource is the most important part for humans to continue their life. One example of the vital role of water resources for human activities is to fulfill food through agriculture and plantations. The availability of water needs for agricultural productivity is certainly an important study to maintain supply capacity and avoid crises in agricultural and plantation foodstuffs. As mandated by the Water Resources Law, the utilization of water resources is aimed at sustainably utilizing water resources by prioritizing the fulfillment of the basic needs of the community fairly. For the sake of the continuity of human life, water resources must be managed properly by paying attention to and protecting the environment. Almost not all the agricultural and plantation areas in the Planting area have irrigation channels that utilize surface water. Consequently, agricultural production does not reach maximum results, because its water needs are very dependent on rainwater. On the other hand, even though there is an irrigation network, there are areas where the availability of water is not sufficient, so that farming activities of farmers cannot get maximum results. This limitation causes farmers to depend on surface water supply, especially during the rainy season so that problems such as prolonged drought can have fatal consequences. One of the efforts to improve agricultural irrigation is to create a groundwater irrigation network by taking water from bore wells.

The Je'neberang River supports the lives of the people of Gowa and Makassar both ecologically and economically. Therefore, this river must be conserved starting from the upstream, downstream to the estuary, one of which is by assessing its trophic status. Trophic status is an indicator of the fertility level of water that can be measured from nutrients, chlorophyll-a content, brightness levels, and other biological activities that occur in an aquatic environment. This research-based community service aims to determine the trophic level status of the Je'neberang River which has been socialized to the community. Based on the output of data analysis obtained, this service activity is focused on educating partners, which is part of socialization. The method is divided into two stages, namely the stage of data collection and testing and the stage of socialization to partners. Socialization to partners is divided into four stages, namely preparation or pre-activity, preparation of socialization materials, implementation of socialization, and evaluation of the sustainability of activities. Socialization activities at the crossing location between Mallengkeri (Makassar) sub-district to the Taeng area in Gowa Regency. Socialization is in the form of countermeasures so that the rate of trophic level can be slowed down naturally, by not using the Je'neberang River as a waste disposal site. The condition of oligotrophic status on the Je'neberang River has been socialized to the community around river users, how important it is to maintain balance or nutritional conditions in the river to preserve the biota/organisms that live in the river.

In Indonesia, gold is typically mined out from epithermal, porphyry and skarn deposit types occurred within volcanic belts along magmatic arc or active continental margin setting. Numerous gold prospects, however, are recently discovered in association with metamorphic and sedimentary rocks. This paper is aimed to discuss a preliminary study on the occurrences and characteristics of the sedimentary rock-hosted low-sulfidation (LS) epithermal gold mineralization in Bastem (Bessengan Tempe) prospect, Luwu district, Sulawesi Island, Indonesia. Detailed geological and hydrothermal alteration mapping was performed to understand the distribution and characteristics of ore mineralization. Representative ore samples taken were analysed for ore chemistry by means of Fire Assay – Atomic Absorption Spectrometry (FA-AAS) and Acid Geochemical Digest - Atomic Absorption Spectrometry (GA-AAS). The results from this work that the Bastem prospect is stratigrapically occupied by Tertiary sedimentary rocks of Toraja formation, which is adjacent to volcanic rocks of Lamasi formation. Gold-bearing quartz±carbonate veins are hosted by mudstone and siltstone of Toraja formation. The quartz-carbonate veins show a typical LS epithermal open space filling texture containing erratic gold grade of up to 7.16 g/t with relatively high besemetals (Pb and Zn) grades of up to >0.4 and >1%, respectively. Based on those various features, the LS epithermal deposit is categorized as “carbonate-basemetal-gold mineralization type”, which might be originated in back arc rift/basin setting. This ‘unconventional’ sedimentary rock hosted-gold mineralization type would be the new target of gold exploration in Indonesia.
