Sungai bedengan yang berada pada Wisata Buper Bedengan Desa selorejo Kecamatan Dau Kabupaten Malang merupakan sungai dengan aliran sedang yang bersumber langsung dari mata air dan mengalir melalui wilayah yang berbatu besar pada daerah tersebut. Sungai bedengan memiliki peran yang sangat penting dalam mendukung sosial ekonomi masyarakat di kelurahan Selorejo. Fungsinya melibatkan penyediaan air irigasi untuk keperluan perkebunan dan pertanian, fungsi sebagai saluran pembuangan hasil kegiatan perkebunan, serta sebagai tempat pembuangan limbah rumah tangga, selain itu juga sungai ini biasanya menjadi tempat favorit wisatawan yang berkunjung. Berdasarkan hal tersebut, Tim PPM kali ini mengusulkan kegiatan PPM ini dilakukan untuk mengetahui kualitas air pada sungai tersebut. Metode pelaksanaan pada kegiatan ini ialah pengukuran kualitas air sungai bedengan, kemudian membandingkan dengan standart baku mutu air sungai, setelah itu akan didapatkan gambaran mengenai keadaan kualitas air sungai tersebut. Selanjutnya ialah melakukan analisis terkait hasil yang didapatkan yang mana pada akhirnya dapat dilakukan upaya upaya yang diharapkan dapat meminimalisir terjadinya pencemaran sungai pada lokasi tersebut

At the end of mining, an open pit coal mine will form a mine sump, also known as a “pit lake”. At PT ABC, the pit wall rock lithology consists of 30% potentially acidic rock and 70% non-acidic rock, with low pH sump water quality. The static test is intended to calculate the balance of acid-forming and acid-consuming components. The static test does not consider the rate of acid formation and neutralization. The objective is to determine the potential for acid formation to occur in the rock. The kinetic test aims to understand the kinetics of acid formation reactions in samples through a simulation of oxidation reactions in rocks. This test can predict long-term weathering characteristics as a function of time. Of the 4 rock samples tested statically, all samples showed PAF (Potencial Acid Forming) screening criteria. The results of the kinetic test showed that sample S1 experienced an increase in pH to 4,43, sample S2 experienced a decrease in pH to 8,03, sample S3 experienced an increase in pH to 2,44, and sample S4 experienced an increase to 7,24.

Tanamerah Village is one of fourteen villages in Saronggi District, Sumenep Regency, East Java. Villagers experience water difficulties during both the rainy season and the dry season. Technical guidance will be carried out for groundwater identification to find out where the groundwater points are located that are able to meet the community's water needs. The method used for identification makes six tracks with varying distances between tracks. The length of each passage is twelve meters, and the depth of each passage is three hundred meters. Identification was carried out on village treasury land with an area of 500 m2. Six tracks in this service, the distance between tracks is 5-8 m, and the length of each track is 12 m. Track 1 was obtained from groundwater at a depth of 80m, and track 2 was obtained from groundwater at a depth of 80 m. Track 3 was obtained from groundwater at a depth of 70 m, and track 4 was obtained from groundwater at a depth of 20 m. Passage 5 is obtained from groundwater at a depth of 20 m, and passage 6 is obtained from groundwater at a depth of 70 m. Recommended drilling point is located on the TM1 line at point 8 with a depth of 80 m.

This study focuses on the evaluation of the production capacity of loading and hauling equipment in limestone mining operations at PT. X, South Sulawesi Province. The selection of this topic is based on the importance of operational efficiency in limestone mining which has a direct impact on the productivity and sustainability of the cement industry. The main objectives of this study are to determine the actual production of loading and hauling equipment, determine the number of equipment needed to meet production targets and identify compatibility factors between mechanical equipment at the mining site. The methods used include field data collection involving measurement of cycle time and production capacity of loading and hauling equipment. The data obtained are then processed using statistical methods to ensure the accuracy of the results. Data analysis is carried out by considering variables such as work efficiency, cycle time, and equipment capacity. The results show that Kobelco SK 480 LC has the highest production capacity (509.34 tons/hour), followed by Komatsu PC 400 (448.25 tons/hour) and PC 300 (417.05 tons/hour). To achieve the Crusher production target of 1450 tons/hour, a combination of loading equipment and dump trucks with a compatibility factor between 0.87 and 0.92 is required, indicating potential for increased efficiency. It is recommended to improve maintenance of equipment and mining roads to optimize productivity.
