Abstract

The rice fields in Bonto Rannu Village, Kajang District, Bulukumba Regency are dominated by rainfed rice fields. This species has limitations in the dry season because irrigation/agricultural irrigation is completely dependent on rainwater. Therefore, it is necessary to identify alternative irrigation sources for the sustainability of farmers' farming activities in Bonto Rannu Village. This study aims to analyze the quantity of groundwater wells by testing in the form of a pump test (pumping test) with the step draw down method. The optimum discharge (Qopt) of well 1 is 0.01876 m3/s or 67.53 m3/hour with an optimum Sw of 2.891 m. This shows that groundwater in well 1 can be pumped at 67.53 m3/hour with a decrease in water level of 2.891 m with the pump condition still technically safe. As for well 2, the optimum discharge (Qopt) is 0.00318 m3/s or 11.45 m3/hour with an optimum Sw of 2.100 m. These data indicate that there are limited groundwater reserves.

Abstract

Springs are a problem in areas where geographic conditions are predominantly hot with low annual rainfall. Water is one of the basic needs for all living things on Earth, both plants, animals and especially humans. If there is a scarcity of spring sources, it is certain that daily activities are very disturbed. Scarcity of springs as happened in Jenetallasa Village greatly influences community activities in the Village. Prolonged drought results in increasingly severe water scarcity that occurs. Based on this problem, a field study was conducted to estimate the aquifer zone. Aquifers are a source of springs located in cavities brought under the surface of the ground which reminisce or flow. Aquifers themselves can be predicted without existence of drilling or excavation. Detection of aquifers can be done using geoelectric methods with different configurations. Our field study this time uses a schlumberger configuration with a length of 120 meters with an approximate depth of 60 meters below ground level.

Abstract

Drought usually occurs, especially during the dry season in Bontoramba, Jeneponto Regency, South Sulawesi. Therefore, it is necessary to study the potential of groundwater to meet the water needs of the Bontoramba community during the dry season. A way to identify groundwater is by using the resistivity method. This method is applied with Schlumberger configuration that gives good results vertically. The purpose of this study was to identify the potential for groundwater both in position and depth based on the results of the interpretation of measurements using the resistivity method of the Schlumberger configuration. This research is experimental research with a descriptive method. Data were processed, analyzed, and interpreted using Res2dinv. Through the results of this interpretation, modeling of the distribution of the aquifer layer in the soil is then carried out which is projected as groundwater. The results showed that the groundwater layer in path 1 and path 2 were on average at a depth of 10-30 m, path 3 and path 4 at a depth more than 30 m from the ground surface.

Abstract

Penelitian ini bertujuan untuk mengetahui area rawan longsor menggunakan metode resistivitas di Desa Samangki Kecamatan Simbang Kabupaten Maros. Penelitian ini dilakukan di Desa Samangki Kecamatan Simbang Kabupaten Maros pada 5 titik di lereng jalur Maros – Bone. Pengukuran dilakukan untuk mendeteksi potensi tanah longsor menggunakan metode resistivitas konfigurasi wenner alpha. Data yang diperoleh berupa besar tegangan dan arus kemudian dianalisis melalui Software Microsoft Excel dan Res2DInv untuk mendapatkan penampang model 2-Dimensi. Hasil penampang 2-D digunakan untuk memperoleh struktur batuan di bawah permukaan bumi. Hasil penelitian menunjukkan adanya lapisan napal pasiran, gamping pasiran, dan gamping koral pada wilayah pengukuran yang merupakan bagian dari formasi tonasa batugamping. Adapun area yang rawan terjadi tanah longsor yaitu pada lintasan 2, lintasan 3, lintasan 4, dan lintasan 5, kecuali lintasan 1 yang masih didominasi oleh batuan yang memiliki nilai resistivitas tinggi dan mampu menahan area yang beresistivitas rendah di bagian atas lereng. Sedangkan ke 4 lintasan lainnya berada di area yang curam dan terindikasi adanya rekahan yang tersaturasi air, sehingga berpotensi terjadi tanah longsor pada jarak yang sama yakni 110 meter.

Abstract

XRF method to determine elemental content and FTIR test to determine the nature of chemical compounds (functional groups) of Litosol soil at the slope (elevation angle) and the distance of the research trajectory lines. The identified elemental levels are Fe, Si, Ti, K, Mn and Ca. Fe represents the highest elemental content value for each research path. Fe for paths (1-2) are 23.82 % and 37.69%, tracks (5-6) are 23.11% and 37.47%, and paths (9-10) are 40.44% and 33.99% at different elevation angles. The lowest element level is Ca. The value of Ca for each track is 0.24% and 0.66% (1-2), 0.28% and 0.30% (5-6) and 0.27% and 0.62% (9-10) for each different elevation angle. The FTIR method to determine functional groups (chemical compounds) uses the same parameters as the XRF method. The O-H functional groups were detected at wave numbers 3698.31 cm-1 and 3620.34 cm-1 with the theoretical accuracy ranges of 3700-3000 cm-1 and 3590-3650 cm-1. The C=C which is a double bond functional group was detected at wave number 1640.8 cm-1 in the theoretical range of 1610-1680 cm-1. The C-H functional group on each track was detected in three different types of wave numbers with values of 908.99 cm-1, 786.86 cm-1 and 746 cm-1, respectively. The range of wave number accuracy for C-H is 690-900 cm-1.
