Water is a source of necessity for humans. Water quality is very important to be considered as the source of clean water. Some people in Maros Baru District use ground wells as the source of water needs. Therefore it is important to know the physical quality and pH level of shallow wells and to know the worthiness of shallow wells in Maros Baru District with reference to Permenkes No.492/ 2010. This study examined the feasibility of water based on the physical quality and the pH level of water taken from shallow wells. The research was carried out directly in field with 14 sampling points scattered in the north, east, south, west and at the center of field. The method in observing pH value is by litmus paper and observation on the physical condition of water, well depth, well diameter and surface level of water. The result shows there were 2 locations with saltwater taste, as the location is near from the sea and rivers, while turbidity of the water influenced by condition of surround environment that was not properly maintained. From data processing, it can be concluded that as many as 5 of the 14 sampling points did not meet the eligibility standards of Permenkes No.492/2010 to be used as a source of clean water intended for drinking water.

One area that has the potential to experience problems with the management and utilization of groundwater is the Makassar area. Several locations in Makassar are experiencing drought, while groundwater is abundant in other parts. In some places, groundwater availability is quite good, but it isn't easy to obtain in others. Of course, this cannot be separated from the hydrogeological conditions in the Makassar area. The purpose of this research is to identify and map the distribution of groundwater in Makassar City. The research uses the resistivity method, with data including potential values, currents, span length, and rock types found in the research location. Based on the resistivity section, there are two types of groundwater: fresh and brackish. The water is brackish in GL1, with a resistivity range of 2.14 – 22.7 Ohm.m. In GL2, with a resistivity range of 0.1 – 728 Ohm.m, the water is Brackish - Fresh, and in GL3, with a resistivity range of 4.47 – 40.1 Ohm.m. The characteristics of the aquifer in the Makassar area are intermittent based on the depth level.

Penelitian ini menganalisis dan merancang geometri jalan tambang di PT Pancaran Surya Abadi, Kabupaten Kutai Kartanegara, dengan memperhatikan standar teknis agar mendukung keselamatan dan efisiensi operasional alat angkut. Studi dilakukan dengan pengumpulan data lapangan meliputi lebar jalan lurus, lebar jalan tikungan, kemiringan jalan (grade), superelevasi, dan cross slope. Analisis desain mengacu pada pedoman AASHTO dan Keputusan Menteri ESDM No.1827/K/30/MEM/2018, serta memanfaatkan perangkat lunak Surpac untuk pemodelan dan perencanaan jalan tambang. Hasil evaluasi menunjukkan bahwa lebar jalan lurus aktual berkisar antara 10 sampai 13,84 meter, sedangkan lebar jalan tikungan bervariasi antara 10,95 sampai 20 meter. Kemiringan jalan aktual berada di antara 7,3% sampai 10,5%, namun sepanjang segmen pengukuran tidak ditemukan nilai superelevasi maupun cross slope yang berarti, karena elevasi sisi kiri, tengah, dan kanan jalan relatif sama. Kondisi tersebut mengindikasikan perlunya perbaikan dalam desain geometri jalan tambang untuk memastikan drainase efektif dan keselamatan alat angkut saat beroperasi, terutama pada tikungan dan area rawan banjir. Studi ini menyimpulkan bahwa jalan tambang di PT Pancaran Surya Abadi masih memerlukan penyesuaian agar memenuhi standar geometri yang ditetapkan, khususnya pada aspek kemiringan melintang dan superelevasi. Rekomendasi teknis disampaikan untuk meningkatkan umur jalan, mengurangi risiko kecelakaan, serta mendukung produktivitas tambang di wilayah dengan topografi dan kondisi iklim tropis seperti Kutai Kartanegara.
