Abstract

Kabupaten Rembang merupakan sebuah kabupaten yang terletak di pesisir Provinsi Jawa Tengah yang tersusun atas Aluvium, Formasi Lidah, Anggota Selorejo, Formasi Paciran, Formasi Mundu, Formasi Ledok, Formasi Wonocolo, Formasi Bulu, Formasi Ngrayong, dan Formasi Tawun. Kabupaten Rembang dan sekitarnya berada pada Zona Non CAT, yang tersusun oleh badan air permukaan, dan beberapa lapisan akuifer. Penelitian ini bertujuan untuk menganalisis hidrogeokimia air tanah di Kabupaten Rembang. Analisis hidrogeokimia dilakukan pada 30 titik minatan, meliputi 8 mata air, 14 sumur bor, 8 sumur gali. Hasil pengujian hidrogeokimia di laboratorium menunjukkan nilai pH air tanah sebesar 7.0 – 7.9. Nilai DHL air tanah sebesar 518 – 7290 μS/cm. Nilai TDS sebesar 345–4860 mg/L. Hasil plot Diagram Stiff menunjukkan adanya enam tipe air tanah (Kalsium Bikarbonat, Natrium Bikarbonat, Natrium Klorida, Magnesium Bikarbonat, Kalsium Sulfat, dan Kalsium Klorida), sedangkan hasil plot Diagram Piper menunjukkan bahwa seluruh sampel masuk ke dalam fasies alkaline earth water predominantly hydrocarbonate. Hasil plot Diagram Gibbs menunjukkan bahwa seluruh sampel masuk ke dalam kategori rock dominance. Berdasarkan analisis hidrogeokimia air tanah, daerah penelitian memiliki kualitas air tanah yang baik untuk digunakan dalam kegiatan sehari-hari.

Abstract

Kelapa Kampit is one of the tin-producing districts in East Belitung, which is composed of the Kelapa Kampit Formation. This mining activity affects water quality, which, of course, is also influenced by geological formations. This study aims to analyze the hydrogeochemistry and heavy metals in shallow groundwater in Kelapa Kampit District using water quality indexes in the form of water quality index and heavy metal pollution index methods. Hydrogeochemical test results showed a pH value of water 4 – 6.77 in the acidic category, a DHL value of 20 – 145 μS/cm, and a TDS value of 14 – 111 mg/L. From the visualization of chemical data, groundwater has various facies. The results of the Stiff Diagram show that water contains predominant calcium, magnesium, sulfate, and bicarbonate ions. The Gibbs diagram results show that the water has not been contaminated. The results of heavy metal testing also showed that the values of Fe2+, Mn2+, Pb2+, Zn2+, and Cu2+ were classified as low, and Al3+ was quite high. The results of water quality testing using the water quality index showed that the research area had excellent water quality, and the results of the heavy metal testing using the HPI method showed a low heavy metal contamination value. Based on hydrogeochemical and heavy metal analysis of shallow groundwater, Kelapa Kampit District has good groundwater quality for sanitation hygiene purposes.

Abstract

Demak Regency is a peri-urban area in Java experiencing an increasing demand for clean water due to population growth and development. Groundwater is the primary source to meet this demand, although its quality is often threatened by pollution from household waste and unprotected septic tanks. This study aims to evaluate groundwater quality in Demak District with the Escherichia coli presence parameter in unconfined aquifers using a GIS-based spatial approach and IDW interpolation method. The geology of the study area includes sandstone, carbonate mudstone, and alluvium lithologies, with most regions having flat slopes. The hydrogeological potential of the study area shows diverse aquifer productivity, with groundwater levels ranging from 0.3–41 meters. The results of the groundwater quality analysis in the study area showed that 47% of the samples exceeded the safe limit for Escherichia coli by Ministry of Health Number 2 Year 2023. The shallow depth of the groundwater table and poor well construction allow the infiltration of contaminants from the land surface into the groundwater, especially from polluting sources around the well. This study provides an essential overview of groundwater quality in the Demak District, which can support sustainable groundwater management and improved sanitation to improve public health.

Abstract

Indonesia represents about 6% of the world's water sources. This shows that Indonesia has abundant water resources. However, the facts show that most areas of Indonesia experience a shortage of clean water supplies. This is because the spring can be lost within a certain period if there is no planning to maintain its availability. The solution offered is to fulfil clean water needs with the Kaizen method. Kaizen is a 5S philosophy that includes Seiri, Seinton, Seiso, Seiketsu, and Shitsuke. This study aims to review the application of Kaizen methods and their sustainability to be applied in Indonesia. The methods used in this study are descriptive observational are aimed at describing and describing phenomena of a scientific and human engineering nature. The results of this study are packaged in the House Model. The House Model is a tool used by an organization using a concept built to transform into action. Some activities in the house model are tailored to meet the needs of partners and further increase the efficiency and effectiveness of the programs being implemented. The program also has good sustainability in community aspects, regulations, and government.
