Abstract

Research has been carried out which aims to determine the quality of drinking water in refill drinking water in Lala Village, Namlea District, Buru Regency. This type of research is quantitative descriptive with a laboratory experimental approach which aims to obtain an overview of the content of Escherichia coli and calcium carbonate (CaCO3) bacteria in refill drinking water. Based on the results of the study, it was found that for the biological quality of drinking water samples at the refill drinking water depot in Lala Village there were two polluted refill drinking water depots and were detected to have an average total Escherichia coli in sample I was 5/100 ml and sample II 5/100 ml. As for the chemical quality, it shows that all drinking water samples consist of 4 samples, the hardness as CaCO3 is still within the normal limit, namely 200.927 to 285.007 mg / l. So it can be concluded that all refill drinking water depots in Lala Village are safe for CaCO3 hardness, while for the biological quality of depot I and depot II are not suitable for consumption.

Abstract

Building a motivating environment can be an organization's most significant challenge because a motivated, satisfied, and committed workforce is harder to find and create. It keeps leaders in an organization evaluating, experimenting, and adapting to different people, including their behaviours, attitudes, personalities and cultures, traditions, habits, and experiences. This study aims to determine and analyze the effect of transformational leadership style and compensation on teacher performance through work motivation at a private madrasah Aliyah in Buru Regency. The descriptive and verification method with a quantitative research approach is used—sampling using the purposive sampling technique, with a sample of 41 teachers. Sources of data used in the study are primary data and secondary data. The study's results indicate that transformational leadership influences work motivation and teacher performance. Likewise, compensation directly influences the motivation and performance of Madrasah Aliyah Alhilaal Namlea Buru Regency teachers. The results of the Sobel test calculator calculation show an indirect effect of transformational leadership on teacher performance through work motivation. Likewise, compensation also has an indirect impact on teacher performance through work motivation. So it can be concluded that work motivation can mediate the relationship between balance and teacher performance at Madrasah Aliyah inBuru Regency. The results of this study can also be used for researchers and further researchers as well as parties who need it as a source of reference and valuable information in adding to the reader's insight

Abstract

Latar Belakang: Para penambang emas di pulau Buru menggunakan bahan kimia berbahaya seperti merkuri, dimana limbah dari hasil penambangan akan mengalir hingga ke lautan dan menyebabkan biota laut tercemar merkuri sehingga perlu selalu dipantau kualitas airnya, karena sangat berdampak bagi ksehatan dan juga lingkungan. Tujuan penelitian ini sebagai rujukan pemerintah dalam pembuatan peraturan daeraha mengenai lingkungan.Metode: Penelitian ini termasuk dalam kategori penelitian lapangan, yaitu data diambil langsung dari sampel dan dianalisis di laboratorium. Indikator terdiri dari analisis fisik, kimia dan biologi dari sampel air sungai dan laut kemudian dideskripsikan.Hasil: Dari hasil analisis laboraturium menunjukan bahwa parameter fisik TDS yang dihasilkan tidak sesuai dengan baku mutu yaitu: Sungai Waelata, Sungai Anahoni, Sungai Kayeli, Laut Teluk Kayeli. Parameter kimia nilai BOD tidak sesuai dengan baku mutu yaitu: Sungai Waeapo, Sungai Waelata, Sungai Anahoni, Sungai Kayeli. Untuk parameter biologi tergolong seuai baku mutu. Wilayah pengamatan yang memiliki nilai kualitas perairan yang kurang baik dibandingkan dengan wilayah lainnya adalah Sungai Anahoni dengan tujuh parameter tidak sesuai baku mutu (suhu, TSS, TDS, kekeruhan, DO, BOD dan COD), Sungai Kayeli memiliki enam parameter tida sesuai dengan baku mutu diantaranya TDS, pH, phosfat, DO, BOD dan COD), Sungai Waelata dengan lima parameter tidak sesuai dengan baku mutu (suhu, TDS, TSS, kekruhan dan BOD).Simpulan: Dari nilai parameter fisik, biologi, dan kimia terlihat bahwa sebagaian besar telah memenuhi baku mutu yang telah ditetapkan, sehingga masih dapat digunakan sesuai dengan fungsinya, namun masih terdapat beberapa parameter yang tidak sesuai denganbaku mutu. ABSTRACT Title: Comparative Analysis of Water Quality that empties into the Waters of Kayeli Bay as the Impact of Illegal MinersBackground: Gold miners on Buru Island use hazardous chemicals such as mercury, whereby the waste from mining will flow into the ocean and cause marine creatures to be polluted with mercury so that the water quality needs to be monitored constantly, because it has a huge impact on health and also the environment. The purpose of this research is as a reference for the government in making regional regulations regarding the environment.Methods: This research is included in field research, where the data is taken directly from the sample and analyzed in the laboratory. The indicators consist of physical, chemical and biological analysis of river and sea water samples which are then described.Results: The results of laboratory analysis show that the physical parameters of the TDS produced are not in accordance with the quality standards, namely: Waelata River, Anahoni River, Kayeli River, Kayeli Bay Sea. The chemical parameter BOD values do not comply with the quality standards, namely: Waeapo River, Waelata River, Anahoni River, Kayeli River. For biological parameters classified according to quality standards. The observation area that has poor water quality values compared to other areas is the Anahoni River with seven parameters not in accordance with quality standards (temperature, TSS, TDS, turbidity, DO, BOD and COD), Kayeli River has six parameters not in accordance with quality standards including TDS, pH, phosphate, DO, BOD and COD), the Waelata River with five parameters not in accordance with quality standards (temperature, TDS, TSS, turbidity and BOD).Conclusion: From the values of the physical, biological and chemical parameters it can be seen that most of them have met the quality standards that have been set, so they can still be used according to their function, but there are still some parameters that are not in accordance with the quality standards.

Abstract

Mercury is widely used in Unlicensed Gold Mining (PETI) in Indonesia, one of which is PETI activities in the Buru Regency area. Traditional gold mining in this area began in 2011, initially starting at the Mount Botak location, Wamsait Hamlet, Dava Village, Waelata District, and was subsequently carried out in four other locations, namely in the Lea Bumi, Gogorea, Derlale/Metar and Waepotih/Waedanga areas. This research aims to determine mercury levels in the soil around gold mining locations. This type of research is a survey with a quantitative approach. This research is divided into several stages, namely: (1) Research design; (2) Field research; (3) Data collection; (4) Laboratory analysis; (5) Data processing. The research results show that there is heavy metal mercury contamination in the soil and plants around the gold mining processing area in Buru Regency. For soil samples, of the 43 samples analyzed, 41 samples were detected with mercury concentrations exceeding the quality standard limit, where the highest concentration reached 18,430 ppm. This indicates that unlicensed gold mining in Buru Regency which uses the heavy metal mercury in the processing process has a serious impact on pollution, especially on the land around the gold mining area.
