The research aims to identify new potential areas for hydrocarbon reserves using seismic interpretation, and tetrophysical analysis, also calculate the volume of reserves in those areas. According to the study, 2 potential areas for hydrocarbon reserves were identified in the Parigi Formation, 2 were identified in the Baturaja Formation, 3 were identified in the Talang Akar Formation, and 1 was identified in the Jatibarang Formation. No new potential areas were discovered in the Cibulakan Formation. The study used petrophysical interpretation of six wells to determine the average values of shale volume (9.57% to 29.87%), effective porosity (19.45% to 21.67%), and water saturation (69.73% to 93.50%) for each potential zone. The TAU-5 well in the Baturaja Formation (Zone 1, Zone 2, Zone 3, and Zone 4) was determined to be the most economically viable zone for production based on the v...

Pelabuhan Tanjung Perak merupakan pelabuhan utama Indonesia timur yang letaknya sebelah utara dari Kota Surabaya di pulau jawa. Pelabuhan ini terletak di selat Surabaya yang menghubungkan laut Jawa ke selat Madura. Pada kawasan Tanjung Perak terdapat dermaga yang di kelola oleh PT Terminal Petikemas Surabaya (TPS). Dermaga PT TPS di bagi menjadi dua yaitu terminal domestik dan terminal internasional. Laju sedimen pada PT TPS sebesar 0.01372 m/hari pada tanggal 18 Agustus 2016 sampai dengan 5 Oktober 2016.jumlah sedimen yang dapat diambil dengan system sand bypassing mencapai 1075,425 m3/hari.

Ikan mata belo (Hilsa kelee) merupakan salah satu spesies ikan pelagis yang didaratkan di Tempat Pelelangan Ikan (TPI) Pelabuhan Perikanan Samudera Cilacap (PPSC) Kabupaten Cilacap. Pemanfaatan ikan mata belo (Hilsa kelee) yang terus-menerus tanpa ada upaya konservasi dapat menyebabkan over fishing. Oleh karena itu, perlu adanya upaya untuk konservasi yang dapat dilakukan dengan berbagai pendekatan, salah satunya adalah kajian taksonomi. Informasi taksonomik tentang ikan mata belo masih terbatas sehingga perlu dilakukan penelitian mengenai karakter morfologi serta karakter meristik dengan dilengkapi karakter truss morphometric ikan mata belo jantan dan betina. Penelitian ini bertujuan mengetahui karakter morfologi, meristik, dan truss morphometric yang dapat digunakan untuk membedakan antara ikan mata belo jantan dan ikan mata belo betina dan unt...

The size of the drain area not only affects the production rate but will also affect the distribution of pressure and saturation as well as the physical properties of the fluid and reservoir rock. Determination of optimum well spacing is important in field development management. This paper presents observations on the effect of the drain area on the production rate, pressure drop, and recovery factor. Simulation of the well model with a cylindrical drain area is used for various sizes of drainage areas. Based on the analysis in this study, it is concluded that the size of the discharge area affects the production rate, recovery factor, and pressure drop. The decrease in pressure affects the release of dissolved gas as indicated by changes in the gas-oil ratio (GOR) curve and the peak of the GOR.

In terms of time, leisure time is free time from all obligations and purposes. Time in daily life is like a resourse. Because have a limited time, just 24 hours in one day. The limited of time should be maximal utilization for activity in everyday. The purpose of this research is to know description of utilize leisure time to factory workers in the PT. Yang Ming International. The kind of this research is qualitative research. This sample is 5 respondents and used key person method. Data colletion technique is pursosive sampling. The result of this research is utilization of leisure time to factory workers in the Yang Ming International, their activities move around in the residence. And be base the kind of leisure time activity, the factory workers have many activities with family and home.

Employing an in-depth case study, this study focuses on three student groups: Kesatuan Aksi Mahasiswa Muslim Indonesia (KAMMI), Gema Pembebasan (GEMAPEM), and the Salafi group within the Campus Da'wah Institute. The research found that these groups act as learning communities and active agents in shaping students' religious understanding and practices. The research also shows that these groups' persuasive and systematic methods are important in spreading their teachings and influence. While this research opens up a new understanding of this phenomenon, several limitations were identified, including the scope of the study being limited to one university and the lack of research on other factors that may be influential. This research contributes to a deeper understanding of the dynamics of the Islamic student movement and its influence on univer...
