Abstract

This research aims to analyze well logging data to determine the aquifer layer of drilled wells in Hulu Sungai Selatan Regency, South Kalimantan. This information is very important for sustainably developing groundwater resources in the region. This research uses well logging data collected from various sources, including resistivity, gamma rays, and spontaneous potential logs. These data are then analyzed using various techniques such as correlation analysis, log interpretation charts, and software to identify aquifer zones based on their characteristic log responses. The analysis succeeded in identifying potential aquifer layers in the wells studied. Aquifers are characterized by resistivity, gamma rays, and lithology. Based on the results of the analysis using WellCad data, four types of rock were obtained, namely: weathered rock (top soil), sand, clay, and sandy clay. Demonstrates the effectiveness of well logging data analysis in identifying and characterizing aquifer layers. Based on these results, it is known that the distribution of confined aquifers and unconfined aquifers has water-carrying properties. So overall it can be concluded that Hulu Sungai Selatan Regency has quite large deep groundwater potential because there are many layers of sand.KEYWORDS: Well logging; aquifer; groundwater; Hulu Sungai Selatan; South Kalimantan.

Abstract

One of the fish in Indonesian waters that has been successfully bred and cultivated is the catfish (Pangasius sp.). In catfish farming, there are several water quality factors that need to be considered, such as temperature and dissolved oxygen levels. Based on the existing description, it is very important to pay attention to the water quality of aquaculture ponds, especially temperature and dissolved oxygen levels for fish survival. This study aims to create an internet of things (IoT) based monitoring system for temperature and dissolved oxygen levels in catfish aquaculture pond water based on NodeMCU ESP8266. Monitoring system is using SEN0237 gravity analog dissolved oxygen sensor, DS18B20 sensor module, NodeMCU ESP8266, 20×4-character liquid-crystal display (LCD), micro secure digital (SD) card module, internet modem. Data from measurements of temperature and dissolved oxygen levels are stored online in the Adafruit.io database in the .csv format and on a micro secure digital (SD) card in the device in the .txt format. The lowest value of dissolved oxygen levels and temperature are 3.4 mg/L or 3.4 ppm and a temperature of 27.9 °C, respectively. Meanwhile, the highest value of dissolved oxygen levels and temperature are 4.6 mg/L or 4.6 ppm and temperature of 30.9 °C, respectively.

Abstract

Kegiatan ini merupakan bagian salah satu cara sosialisasi hidup sehat era endemi atau pasca covid-19. Ulasan ringkasanya dapat disampaikan berikut ini; Pada akhir abad ke-18, Edward Jenner, seorang dokter Inggris, membuat terobosan penting dalam perkembangan vaksinasi. Jenner mengembangkan vaksin cacar pertama yang berhasil pada tahun 1796. Observasi pada para pemerah susu yang tertular/terpapar cacar sapi, yang menunjukan gejala tidak terlalu parah, dan gejala itu akibat dari terlindungi cacar sapi. Bintil-bintil cacar sapi disuntikan ulang pada seorang anak laki-laki, yang menunjukkan kekebalan terhadap cacar. Hal ini menjadi dasar bagi vaksinasi modern. Selanjutnya, Pada akhir abad ke-19, Louis Pasteur mengembangkan vaksin rabies, yang menandai tonggak sejarah lain dalam sejarah vaksin. Hasil karyanya menunjukkan bahwa vaksin dapat mencegah penyakit yang disebabkan oleh infeksi virus dan/atau bakteri. Keberhasilan vaksinasi cacar menyebabkan kampanye vaksinasi yang meluas untuk membasmi cacar. Para ilmuwan terus meneliti dan mengembangkan vaksin baru untuk memerangi penyakit menular yang baru muncul dan memperbaiki vaksin yang sudah ada. Contoh penting termasuk pengembangan vaksin untuk melawan human papillomavirus (HPV), retrovirus, dan covid-19.

Abstract

Peatlands have a crucial role in the global regulation of climate, the sequestration of carbon, and the conservation of biodiversity. Daily human activities and climate change have caused various environmental changes and ecological relationships for peatlands. An important thing to worry about is the decline in water quality, which harms the health and welfare of local communities that depend on clean water sources and drinking water from natural water. Additionally, the escalating demand for clean water necessitates substantial efforts in processing peatland water resources. The degradation in water quality harms the ecology and health of humans who use it for daily needs. Single Flow Ultrafiltration technology has emerged as a promising water treatment method, showing great potential in treating peat water while maintaining the ecological balance of peatlands. This research aims to evaluate the effectiveness of a combined treatment process consisting of filtration, absorption, microfiltration, and single-flow ultrafiltration. The application of this technology is carried out in the South Kalimantan region, with water processing stages, namely raw water filtration, semi-finished raw water filtration, ultrafiltration, and an ultraviolet irradiation process at the final stage so that the water is ready for consumption. Using both techniques, empirical methodologies were utilized to analyze the results of water quality and production capacity. This study proposes single-flow ultrafiltration to treat peat water for daily use. This research shows that the single-stream ultrafiltration treatment method for peat water gives a better water quality result than ordinary ultrafiltration treatment. This is indicated by the percentage difference in decreasing TDS values by 149%, turbidity by 200%, and color by 500%, increasing pH by 14.9%, decreasing nitrite by 135%
