Abstract

Selat Badung merupakan percabangan outlet dari Selat Lombok yang berada di antara Pulau Bali dan Pulau Nusa Penida. Kecepatan arus di Selat Badung berkisar dari 0,2 cm/s - 204,3 cm/s. Kajian arus di lokasi ini diperlukan untuk mengetahui pola dan karakteristik arus berdasarkan komponen harmonik pasang surut. Pengukuran data di perairan lokasi penelitian dilaksanakan pada tanggal 20 Juni 2014 - 5 Juli 2014 dengan interval perekaman 30 menit. Metode yang digunakan dalam penelitian ini menggunakan software Matlab dengan toolbox t_tide yang dapat memisahkan data arus perekaman menjadi data arus harmonik dan non-harmonik dengan mengeluarkan komponen pasang surut yang berpengaruh terhadap keberlangsungan arus harmoniknya. Ketiga data arus ini akan dianalisis untuk mengetahui pola dan karakteristiknya. Berdasarkan hasil penelitian, pola arus didominasi oleh arus non harmonik ke arah tenggara. Komponen harmonik yang berpengaruh besar pada lokasi tersebut adalah Msf, M2 dan S2.

Abstract

The partner of this community service activity is Islamic Boarding Schoo of Tahfidzul Qur'an of Miftahul Jannah Putri in Pamanjengan, Moncongloe, Maros Regency. This boarding school guides 10 students from underprivileged families. The partner's main problem is the difficulty in meeting water needs for daily needs because there is no clean water service available through the network of Regional Drinking Water Companies and limited groundwater production from existing bore wells. Therefore, the boarding school manager and students tries to get ground water by developing the addition of groundwater wells as seen from the results of the pre-test. This boarding school has an area of ​​800 m2 making it possible to develop a better groundwater borehole. However, there are concerns about its success because several well drillings that have been carried out in its vicinity have not succeeded in obtaining water of the quality and quantity as expected. Therefore, this groundwater well development activity is carried out in stages based on a groundwater science approach which includes the stages of surface mapping, geoelectrical measurement, groundwater drilling, well construction and pumping. Drilling was carried out to a depth of 60 meters. The drilled well was pumped at a flow rate of 0.40 liters/second (1,440 liters/hour) and reached steady state at a water table drop of 1.60 meters. Thus, this community service activity was declared successful in accordance with the output target with the availability of groundwater production wells of good quality and sufficient quantity to meet the needs of the boarding school. The post-test results show that the existence of the well gives confidence that water needs will be met with additional groundwater drilled wells from this activity.
