n this research, soil improvement is done by using waste of snail shells (LCK) in Desa Ulak Kembahang II, Kecamatan Lubuk Keliat, Kabupaten Ogan Ilir, Sumatera Selatan and soil from Tanjung Api-api Area, Gasing , Kabupaten Banyuasin, Sumatera Selatan . The soil used is a type of problematic soil that is expansive clay, which is known LL value (Liquid limit) more than 35%. The LCK used is then used as powder. Furthermore, there are 5 variations of percentage of addition of snail shell powder (SCK) with soil, and give the curing time is for 0, 1 and 7 days. Results from CBR Unsoaked (US) Testing resulted in the addition of SCK at a certain percentage and the curing time could increase the value of CBR expansive clay soil. The highest value of CBR Unsoaked on variation of percentage of SCK increase as much as 11% in the curing curing time for 7 days that is equal to 5.6% for the value of CBR US which in the original land has a CBR value of 3.5%. The result analysis of SEM-EDX test on soil mixture and SCK known SCK works as filler which fill the cavity found in soil grains and the main element of soil known as SiO2 and Al2O3 forming binder material with CaO.

Pertambahan jumlah penduduk yang semakin meningkat secara eksponensial menyebabkan meningkatnya kebutuhan akan air bersih. Disisi lain, penyediaan air bersih merupakan masalah yang sering terjadi baik dari segi kuantitas maupun kualitasnya. Krisis air bersih sering terjadi terutama di kota-kota besar termasuk di Indonesia. Solusi yang dapat dilakukan untuk memecahkan masalah tersebut adalah dengan mencari sumber air bersih alternatif yang murah dan mudah didapat. Salah satu sumber air bersih yang sering terlupakan adalah air hujan. Volume air hujan yang tidak terpakai dapat dimanfaatkan dan digunakan sebagai pengganti air bersih. Air hujan dapat ditangkap dan disimpan dengan suatu sistem sederhana yang biasa disebut dengan sistem rainwater harvesting (RWH). Penerapan sistem RWH di negara-negara berkembang dirasa masih kurang jika dibandingkan dengan penerapan di negara maju. Banyak paradigma dan asumsi masyarakat yang masih salah terhadap sistem tersebut. Peran pemerintah dianggap sangat penting dalam keberhasilan penerapan sistem RWH di Indonesia. Studi ini bertujuan untuk mempelajari respons masyarakat terhadap sistem tersebut. Suatu bentuk kuesioner dikembangkan untuk menganalisis ketertarikan masyarakat dalam penerapan sistem RWH sehingga dapat dijadikan gambaran dan masukan pemerintah agar keberhasilan penerapan sistem tersebut dapat lebih ditingkatkan. Dari hasil kuseioner dapat ditarik kesimpulan bahwa masyarakat tertarik untuk menerapkan sistem RWH hanya saja dengan kesediaan untuk mengeluarkan biaya yang lebih kecil dari biaya yang seharusnya dikeluarkan.

According to Public Works Office of Palembang City, Buah Watershed is listed as one of priority areas that require immediate flood management actions. Flat terrain, high rainfall intensity, tidal fluctuation worsens by massive land use change, are major causes that increase surface water runoff. Therefore, retention basins as one of technical solutions are expected to accommodate runoff discharge and reduce flood. This study aims to analyze the existing hydrological conditions of Buah watershed and to simulate the effectiveness of designed retention basins on peak flow reduction. Hydrological analysis using SCS Unit Hydrograph Model, HEC-HMS combine with spatial analysis using GIS in 26 subcatchment areas resulted on peak discharges range from 1,27 m3/s – 15,71 m3/s. Furthermore, there are 12 proposed retention basins within study area ranges from 0,580 Ha – 3,967 Ha that are designed to reduce the peak discharge. Simulation result of flood discharge reduction using HEC-HMS indicates that the effectiveness of retention basins in proposed locations varies from 0,03% - 80,05% depending on watershed areas, land availability, and the depth of retention basins.

Rainfall data are widely used to predict regional rainfall. Limited rainfall data is a problem that has an impact on decreasing accuracy, one of which is in the area of South Sumatra. This can be overcome by using satellites. However, to utilize satellitebased rainfall data, it is necessary to carry out an analysis to determine the accuracy of rainfall data. This research aims to evaluate rainfall data from the GPM satellite and PERSIANN satellite with validation and calibration analysis so that the value of rainfall data from the Satellite is close to the measurement result and can be used to estimate monthly rainfall. In this study, the data used were measured monthly rainfall in the field, GPM, and PERSIANN obtained from 9 South Sumatra districts for 2019 until 2021. The research method was validated using correlation coefficient, Root Mean Square Error (RMSE), and Mean Absolute Error (MAE). Calibration is done using a combination method, a solver algorithm in Microsoft Excel, and manually. The estimated monthly rainfall analysis is carried out using the isohyet method with the IDW interpolation method. The research results were obtained based on the validation and calibration of monthly rainfall data showing that data from the GPM showing it is closer to the results of field rainfall measurements than the data obtained from PERSIANN satellite. Based on the results of research on satellite data that has been calibrated, it can be used to estimate monthly rainfall in the South Sumatra Region

ABSTRACT: Based on data from the World Health Organization (2018), the highest cause of death for the Indonesian population is caused by cardiovascular disease (35%), cancer (12%), chronic respiratory disease (6%), and diabetes (6%). The most widely used natural antioxidants are phenolic compounds. Phenolic compounds have an important role as antioxidants because of the presence of hydroxyl substituents and aromatic structures capable of scavenging free radicals. One of the plants that contain natural antioxidants is Chinese petai. According to research conducted by Talubmook and Buddhakala (2013), it was reported that repeated administration of ethanol extract of Chinese petai leaves at a dose of 250 mg/kg in rats induced by Streptozotocin for eight weeks could reduce blood glucose levels. The potential of using Chinese Petai Leaves as a natural medicine for diabetes has been socialized to the younger generation, especially high school students, to find out the benefits of plants, one of which is Chinese petai as a diabetes medicine. This is to open up students insight to research plants. The socialization was carried out for students of SMAN 10 Palembang. This activity was attended by 50 students of SMAN 10 Palembang and accompanied by 2 supervising teachers

South Sumatra Province is a province that is flowed by many rivers, including the Musi River, the longest river on the island of Sumatra. The condition of inadequate irrigation infrastructure means that farmers in Menten Village can only plant one crop per year. This study aimed to determine the irrigation water needs of tertiary canals and design the dimensions of connectivity and tertiary channels. Repairing the irrigation network in the village is planned to increase the productivity of agricultural land to two plantings in one year with a cropping pattern of rice and crops. This research was conducted following the following stages Calculation of Irrigation Water Needs, Calculation of Surface Runoff Discharge, Calculation of Channels Design Discharge, Calculation and determination of the dimensions of Connectivity and Tertiary Irrigation Channels. The study results obtained a Need Field Requirement (NFR) value of 1.572 l/s/ha with a maximum irrigation water requirement of 2.418 l/s.ha. To increase menten agricultural yields, a planting pattern of 2 times is planned. The planned channel is an open trapezoidal channel that functions as a carrier channel and a discharge channel namely rice and crops. There are three connectivity irrigation channels. While there are 25 tertiary irrigation canals. The results of this research can be used reference to improve irrigation systems that are still not optimal.
