Abstract

Kelurahan Pantai Amal Kota Tarakan berbatasan langsung dengan lautan yang dapat mengakibatkan rentannya kondisi kualitas air tanah. Sumur bor sebagai salah satu upaya penyediaan air bersih berpotensi mengalami intrusi air laut. Intrusi air laut merupakan proses infiltrasi air laut ke dalam tanah. Penelitian ini bertujuan untuk mendeteksi potensi intrusi air laut dengan pengukuran Total Dissolved Solids (TDS) dan konduktivitas di Kelurahan Pantai Amal Kota Tarakan. Penelitian dilakukan pada 5 lokasi sampling. Penentuan lokasi dilakukan secara purpossive sampling, sedangkan metode yang digunakan untuk melihat keterkaitan antar parameter adalah regresi linear berganda. Hasil penelitian menunjukkan bahwa pengukuran TDS secara berturut-turut 62; 60,3; 146; 57; dan 153 mg/L. Nilai tersebut masih di bawah standar baku mutu air berdasarkan Permenkes RI No 32 Tahun 2017 untuk keperluan hiegiene sanitasi. Konduktivitas tiap stasiun secara berturut-turut dengan jarak antara sumur bor ke garis pantai adalah 310,45 µS/cm dan 692 m; 1125 µS/cm dan 62 m; 239 µS/cm dan 163 m; 1019 µS/cm dan 112 m; serta 406 µS/cm dan 360 m. Hasil analisis parameter konduktivitas dan TDS menunjukkan bahwa tidak terdeteksi adanya intrusi air laut pada sumur bor Pantai Amal Tarakan. Analisis menggunakan regresi linear berganda juga menunjukkan bahwa tidak ada pengaruh antara jarak dan kedalaman terhadap konduktivitas.Pantai Amal Village, Tarakan City, is directly adjacent to the ocean leads to the vulnerability of groundwater quality conditions. Drill well, one of the efforts to provide clean water, has the potential to experience seawater intrusion. Seawater intrusion is the process of infiltrating seawater into the ground. This study aims to detect potential seawater intrusion by measuring TDS and conductivity in Pantai Amal Village, Tarakan City. The study was conducted at five sampling locations. The location is determined by purposive sampling, while the method used to see the relationship between parameters was multiple linear regression. The results showed that the TDS measurements were 62; 60.3; 146; 57; and 153 mg/L. This value is still below the water quality standard based on the Ministry of Health of the Republic of Indonesia No. 32 of 2017 for sanitation hygiene purposes. The conductivity for each station successively with the distance between the borehole to the shoreline are 310.45 µS/cm and 692 m; 1125 µS/cm and 62 m; 239 µS/cm and 163 m; 1019 µS/cm and 112 m; and 406 µS/cm and 360 m. The results of the analysis of conductivity and TDS showed that no sea water intrusion was detected in the drilled wells of Pantai Amal Tarakan. Analysis using multiple linear regression also shows that there is no influence between distance and depth on conductivity.

Abstract

Consumption is inseparable from the rules and requirements set by Islamic teachings. However, in consuming, we must behave according to the standards and ethics of consumption in the Islamic economy. Therefore, in the order of life, Islam has regulated how humans can carry out activities that can be consumed so that they are beneficial to their lives. To achieve this goal, an understanding of Muslim consumer behavior is needed. In this case, Yusuf Al-Qardhawi explains how to consume, rules and correct behavior according to the recommendations of the Qur'an and Sunnah and how to apply them in life in an Islamic economic perspective. In consuming, Jambi City students must follow Yusuf Al-Qardhawi's consumer standards and ethics. The type of research used is descriptive qualitative. The data in this study were obtained from primary data and secondary data. With data collection techniques, namely interviews, observation and documentation.  The results of this study indicate several things that happen to students who drink liquor in the city of Jambi, namely: 1) Spending wealth for good and staying away from miserliness can be interpreted as using assets owned for self-interest as well as a way to worship Allah SWT. Jambi City students have not fully implemented the concept of spending wealth properly and avoiding extravagance or israf. 2) Islam prohibits excessive consumption of wealth for useful and not excessive purposes (waste/israf). 3) Modesty in spending wealth can be seen from the attitude between miserly and miserly, excessive behavior and attitudes in between, including the attitude of luxury. This implementation should be in everyone.
