The study area is divided into 5 tracks, 2 tracks along 100 meters and 3 tracks along 200 meters. Tracks with length 100 meters has space 5 meters and the track with length 200 meters has space of 10 meters. The value obtained from the measurement is the current and potential values, the value is used to obtain the apparent resistivity. The apparent resistivity value is then inverted using Res2Dinv software into 2 dimensional form. The inversion results in 3 cross-sectional resistivity imaged with color and each color indicates a sunder ground resistivity value. Based on the rock resistivity table, ground water has a resistivity value between 30-100 Ω.m. From the cross-sectional resistivity it is found that all tracks have a potential ground water content and the location varies from 2.5 to 34.6 meters below the soil surface. The largest groundwater potential is on track 3 and the smallest is on track 5. Based on its groundwater position in Muaro Pijoan Village includes shallow groundwater.

Eksplorasi potensi panas bumi diklaim sebagai tambang ramah lingkungan, maksudnya tidak terlalu banyak merusak dan tidak terlalu membahayakan lingkungan. Sejatinya benar, namun daerah panas bumi selalu berafiliasi dengan topografi yang sangat kasar, lerengnya terjal, dan jarang dijumpai tanah datar yang luas. Hal ini menyebabkan daerah di sekitar panas bumi rawan terhadap tanah longsor. Jenis batuan yang mudah lepas-lepas, membuat tingkat kerawanan terhadap kemungkinan tanah longsor semakin meningkat. Mengingat daerah panas bumi adalah daerah yang rawan terhadap bencana tanah longsor, maka perlu dilakukan pemetaan daerah rawan longsor untuk meminimalkan korban dan kerugian akibat bencana tersebut. Berdasarkan analisis menggunakan metode probabilistik frekuensi rasio, di sekitar daerah WKP panas bumi, 28,71% adalah daerah yang sangat rawan terhadap bencana longsor, 56,23% masuk dalam kategori rawan longsor, dan hanya 15,06% saja daerah yang aman terhadap bencana longsor tersebut.

The extreme weather that occurred on January 22-24, 2019 in the Makassar city and surrounding areas caused massive flooding in the downstream area of the Bili-Bili DAM which covered 5 districts and cities, namely Gowa Regency, Makassar City, Jeneponto Regency, Maros Regency, and Selayar Regency. There 6757 people were displaced and tens of hectares of rice fields and housing were inundated. As a form of evaluation in the context of disaster mitigation efforts if similar or larger events occur in the future, it is very important to do a floods simulation to mapping which areas will be affected by flood inundation if the Bili-Bili DAM collapses. The software used to simulate flooding in this study is HEC-RAS 2D. The object of research is focused in the city of Makassar which is a densely populated city center and other vital objects. The parameters analyzed are the distribution of flood inundation area and the depth of flood inundation. Simulation results that have been calibrated will be used as a reference for disaster mitigation planning.

Indonesia is a country that has extraordinary natural resources, both biological and non-biological natural resources. Indonesia has a great opportunity in utilizing natural resources to improve the welfare of the people. Unfortunately, Indonesia has not been yet able to exploit all of that. The prices of agricultural products are quite high but ironically the welfare of farmers has not improved either. On the other hand, other natural resources from the marine and earth sector also have export potential, but in fact these potentials have not had a significant influence. One of the causes of the suboptimal use of natural resources in Indonesia is the lack of integration of technology in developing the potential of the biodiversity. One of the efforts made to optimize the potential for life is to apply the concept of physics, which uses the concept of pit heat in the “sanggai” engine technology. This machine can be used to optimize the potential of agriculture in Indonesia. Pit heat technology can dry food without damaging the vitamin content. This technology does not damage the protein structure of food substances so that the application of technology on this machine can be used to optimize the potential of agriculture in Indonesia.

Peningkatan produksi suatu industri selalu diikuti oleh peningkatan produksi limbah yang dihasilkan. Industri batik skala rumah tangga umumnya juga belum memiliki instalasi pengolahan limbah cair sehingga limbah langsung dibuang ke lingkungan atau badan air. Hal ini memberikan dampak yang buruk terhadap lingkungan. Penelitian ini bertujuan membuat suatu teknologi pengolahan limbah cair menggunakan metode elektrokoagulasi yang diintegrasikan dengan sistem filter dan menguji efisiensinya terhadap kenaikan kadar keasaman limbah dan penurunan jumlah padatan terlarut (TDS) dari limbah tersebut. Sampel yang digunakan merupakan limbah batik dari salah satu industri batik di kota Jambi sejumlah 20 liter. Elektroda yang digunakan terbuat dari aluminium sebagai anoda dan besi sebagai katoda. Jumlah katoda dan anoda masing-masingnya adalah 4 buah dengan ukuran 60cm x 30cm x 3cm. Tegangan yang digunakan adalah 40 Volt dengan memvariasikan jarak antar elektroda dan waktu pengolahan limbah. Sebelum limbah diolah menggunakan reaktor dilakukan penyaringan dan analisis karakter awal terlebih dahulu. Hasil penelitian menunjukkan efisiensi reaktor elektrokoagulasi dalam menaikkan pH mencapai 60% hingga 123% dengan rata-rata kenaikan pH 80,83%. Pada perlakuan yang sama, metode elektrokoagulasi memiliki efisiensi dalam menurunkan konsentrasi TDS hingga 50,56 %. Hal ini menunjukkan bahwa metode ini cukup efektif dalam proses pengolahan limbah cair hingga sesuai baku mutu limbah cair.
