Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemia, posing a global health threat. Current diabetes treatments often rely on synthetic drugs with side effects, prompting the search for safer natural alternatives. This study investigated the secondary metabolic compounds in methanol extract from M. oleifera seeds and evaluated their antidiabetic activity. The α-amylase enzyme was analyzed to determine optimal incubation time, pH, and temperature. The antidiabetic activity was assessed via α-amylase inhibition using in vitro and in silico methods. Phytochemical screening revealed the presence of flavonoids, alkaloids, and tannins in the extract. Optimal enzyme conditions were 30 minutes of incubation, pH 6.9, and 25 °C. The extract showed the highest activity at 15% concentration with 67.94% inhibition and an IC50 of 15.38%, compared to acarbose with 41.76% inhibition and an IC50 of 17.89%. In silico analysis indicated that 9-octadecanoic acid (Z) methyl ester had a lower inhibition constant and binding energy (2.67 mM and -3.51 kcal/mol) than acarbose (15.72 mM and -2.46 kcal/mol), suggesting a higher enzyme affinity. These findings suggest that M. oleifera seeds contain compounds with potential as antidiabetic agents.

The coastal area of Segeri sub-district, Pangkajene and Kepulauan Regency is a zone that is prone to natural phenomena of sea level rise. The impact received due to this phenomenon is something that needs to be studied to identify the level of coastal vulnerability and project changes in coastal vulnerability in the future. This study aims to calculate the coastal vulnerability index and project changes in vulnerability in the future due to changes in factors that affect coastal vulnerability.This research was conducted in August – December 2022 in Segeri District, namely in, Bone, Bawasalo and Bonto Matene Villages. The methods or approaches used in analyzing the data are: 1) analysis of coastal ecosystems and resources, 2) analysis of the physical and social characteristics of the community, 3) analysis of the vulnerability of the coastal environment. The Vulnerability Scoping Diagram (VSD) models places exposure, sensitivity and adaptive capacity as dimensions of vulnerability. The components of the exposure dimension consist of coastal dynamics, natural disturbances and population. The components of the sensitivity dimension are the characteristics of the coast, land use, and population settlements. The dimensions of adaptability include coastal habitats and marine conservation areas. Based on the scores of each parameter on the three dimensions, the coastal vulnerability index (IKP) in the three locations is in the range of IKP values of 7.96 - 9.59 which is included in the category of moderate vulnerability. Factors that are very influential on the IKP are the dimensions of sensitivity including: erosion, waves and tides caused by oceanographic factors so that if adaptation and mitigation efforts are not carried out, it is likely that in the next 5-10 years, the level of vulnerability can become high and even very high. Adaptation efforts that can be done are strengthening the coastal border area, planting and expanding mangrove trees in the coastal area of Segeri.

Coconut, particularly coconut water, serves many purposes in people's lives. Coconut water is generally consumed with the young fruit, but old coconut water is frequently discarded into the environment. Therefore, integrating coconut water into a product has a high economic value. The aims of this community service is to process coconut water into nata de coco by empowering the community through training for PKK members. This program's methodology included partner problem analysis and the available problem-solving strategy, which consists of counselling, training, and collecting data. The implementation of this activity resulted in numerous benefits, particularly increased public understanding of the role of coconut water in daily life, such as its nutritional value, processed products such as nata de coco, and other advantages. Based on the data collected, it is known that all participants have differing levels of knowledge about nata de coco products, namely 10% of participants know very well, 30% of participants know, and 12% of participants know little. However, 58% of participants were totally ignorant that coconut water is the starting material in nata de coco. Following the training, all participants understood that coconut water was the raw material in nata de coco. On the other hands, 75% of the participants were very understanding, 20% were quite understanding, and only 5% had a basic understanding of how to make nata de coco. These findings indicate that the solution of the activities carried out is extremely effective in increasing the participants' understanding and interest in making nata de coco, which can encourage the creation of "home industry" based jobs in the community, particularly in Tiroang Village.Â

The Punagaya Steam Power Plant (PLTU) is one of Power Plant in the Southern Sulawesi system. Apart from having a positive impact, PLTU can have a negative impact on the environment due to burning coal as fuel. One of the dangerous air pollutants that is often found is Total Suspended Particulate or TSP. This research aims to determine changes in TSP, PM2.5 and PM10 concentration values at the Punagaya PLTU location from May 2022 and June 2023. The method for measuring concentrations of TSP, PM10, and PM2.5 air particles uses High Volume Air Sampler (HVAS) equipment with gravimetric method. Based on the analysis results of air particles around the Punagaya PLTU, the concentrations of TSP, PM10 and PM2.5 per 24 hours at the location still meet the ambient air quality standards set by the government. TSP in the Boiler Area (U1) is in the blue (medium) category, while other measurement locations for TSP, PM10 and PM2.5 at both times are still in the green (good) ISPU category
