Abstract

Groundwater quality is an important parameter for determining the initial character of an area before infrastructure development. This study aims to determine the initial condition of groundwater quality around the planned construction site of Building X in the Arfai Village, Manokwari, based on physical, chemical, and microbiological parameters. Groundwater samples were taken from two wells located near the activity site, namely the Financial and Development Supervisory Board well and the Religion Governemntal Offive office well. The samples were analyzed using applicable water quality testing methods and compared with the class 2 river water quality standards in Government Regulation of the Republic of Indonesia Number 22 of 2021 Appendix VI and the drinking water quality standards in Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. For physical parameters, the water temperature was between 29.8–30.0°C, electrical conductivity was 332–580 µS/cm, and the concentrations of TDS, TSS, and turbidity were relatively low. Chemical parameters measured were neutral to slightly alkaline pH (7.16–7.66), BOD <2 mg/L, COD <3 mg/L, and DO of 4.3–5.1 mg/L, indicating low organic matter load. Concentrations of sulfate, nutrients, fluoride, and dissolved metals were relatively low, while oil and grease and total detergent did not indicate significant pollutant input. Microbiological parameters such as fecal coliform and total coliform were also at very low concentrations or below the detection limit. Overall, groundwater quality at both observation points remained in good condition and did not show significant anthropogenic pressure.

Abstract

Evaluasi slip velocity merupakan aspek kritis dalam menjamin efisiensi pengangkatan cutting selama operasi pemboran. Penelitian ini menganalisis kinerja transportasi cutting pada Sumur BSU Lapangan Bunyu, Tujuannya   untuk mengetahui apakah serbuk bor terangkat dengan baik atau tidak, sudah optimal atau belum dengan membandingkan dua cara.  Metode yang digunakan metode Chien Correlation dan metode Moore Correlation dengan mengintegrasikan parameter rheologi lumpur dan geometri sumur, dimana data dari pengamatan langsung dilapangan. Hasil penelitian menunjukkan bahwa pada interval kedalaman 5762-8823 ft, nilai slip velocity Chien (0,092-0,156 ft/detik), sedang nilai slip velocity Moore (0.0054-0.0126 ft/detik),  secara konsisten lebih rendah dibandingkan kecepatan kritis (3.6758-4.7727 ft/detik), dengan cutting transport ratio Chien mencapai 90,07-93,90%, sedangkan cutting transport ratio Moore mencapai 99.2609 % sampai 99.66% Kondisi ini mengindikasikan pengangkatan cutting yang optimal dan aliran laminer yang terjaga, sehingga berhasil mencegah risiko pipe sticking dan mempertahankan integritas formasi. Temuan penelitian merekomendasikan penerapan metode ini sebagai standar evaluasi hidrolika pemboran dengan memperhatikan variasi karakteristik formasi pada studi lanjutan
