Abstract

VALORANT is an online team-based first-person shooter game developed by Riot Games. Currently VALORANT is popular among gamers because the game is similar to the Counter Strike but is given a skill set like the Overwatch. Now players on Indonesia are 560k player which so big and interesting to know the factors of this phenomenon. This study aims to determine the factors of social influence impacted the acceptance rate. The research model used in this study is TAM which is then modified as needed by using 6 constructs, namely Perceived Usefulness, Perceived Ease of Use, Social Influence, Attitude Toward Use, Intention to Use and Actual Usage as representatives of acceptance. The method of data collection in this study was to distribute surveys to 105 respondents in Jakarta. The results show that all variables affect Actual Usage except Perceived Ease of Use, although most respondents feel that this game is easy to understand. The results that have been discussed can be used as empirical recommendations to developers who want to make similar games.

Abstract

Formasi Jatiluhur sering digunakan sebagai analogi reservoir untuk sistem minyak dan gas di Cekungan Jawa Barat Utara. Penelitian ini berfokus pada Formasi Jatiluhur, bagian dari batuan sedimen berumur Miosen Tengah yang tersingkap di bagian utara Cekungan Bogor, khususnya di wilayah Bogor dan Cianjur. Formasi ini berumur ekuivalen dengan Formasi Cibulakan yang terdapat di Cekungan Jawa Barat Utara. Tujuan utama penelitian adalah untuk mengidentifikasi litofasies dan sistem pengendapan Formasi Jatiluhur di sekitar Sungai Cikeruh, Sentul, Bogor. Metode yang digunakan meliputi observasi lapangan terhadap batuan sedimen, pengambilan 70 sampel untuk analisis laboratorium (mikropaleontologi dan sedimentologi), serta pencatatan litologi dan struktur sedimen. Hasil penelitian menunjukkan keberagaman litofasies, seperti batupasir dan batulempung, yang mencerminkan mekanisme pengendapan turbidit dalam lingkungan neritik luar hingga batial, dengan pola pengendapan yang berulang. Temuan ini diharapkan dapat memperkaya pemahaman mengenai sejarah geologi dan dinamika sedimentasi di wilayah Cekungan Bogor.

Abstract

Cekungan Sumatra Tengah merupakan cekungan sedimen tersier krusial di Indonesia. Lapangan RJ yang berada di Cekungan Sumatra Tengah memiliki data yang menarik diantaranya data log dan batuan inti yang mampu memberikan informasi mengenai karakteristik litologi, lingkungan pengendapan, dan fasies sementara dipmeter memberikan informasi mengenai arus purba reservoir batupasir A, B, dan C. Meskipun penelitian paleogeografi di Cekungan Sumatra Tengah telah banyak dilakukan, akan tetapi penelitian yang menggunakan data dipmeter masih terbilang jarang, terlebih pada Formasi Bekasap dan lapangan RJ, serta potensinya masih belum sepenuhnya diperoleh. Penelitian ini bertujuan untuk mengetahui karakteristik litologi, fasies, dan arus purba reservoir batupasir A, B, dan C Formasi Bekasap, lapangan RJ, Cekungan Sumatra Tengah. Penelitian ini dilakukan dengan menggunakan metode integrasi analisis data log, deskripsi batuan inti, dan analisis dipmeter. Penelitian ini menghasilkan karakteristik litologi reservoir batupasir A dengan karakteristik litologi batupasir, kaolinit, putih, ukuran butir halus sampai kasar, tidak mengandung calcareous, sortasi buruk, reservoir batupasir B memiliki karakteristik litologi batupasir interlaminasi dengan batulanau, putih keabuan, ukuran butir sedang hingga halus, tidak mengandung calcareous, kekompakan keras, sortasi baik, dan reservoir batupasir C memiliki karakteristik litologi batupasir, very silty, clayey, glaukonit melimpah, abu-abu, hingga abu-abu muda, ukuran butir sangat halus, struktur calcareous, sortasi baik. Reservoir Batupasir A memiliki tiga jenis fasies yakni tidal bar axis, tidal bar off-axis, dan tidal bar margin, reservoir batupasir B dan C memiliki dua jenis fasies yakni tidal bar off-axis dan tidal bar margin. Reservoir batupasir A, B, dan C memiliki arus purba dominan arah timur laut-barat daya, dengan pola arus polymodal yang menunjukkan lingkungan pengendapan tidal bar. The Central Sumatra Basin is a crucial tertiary sedimentary basin in Indonesia. The RJ field in the Central Sumatra Basin has interesting data, including log data and core rock data that can provide information about lithological characteristics, sedimentary environments, and facies, while dipmeter data provides information about paleocurrents in sandstone reservoirs A, B, and C. Although paleogeographic research in the Central Sumatra Basin has been conducted extensively, research using dipmeter data is still relatively rare, especially in the Bekasap Formation and RJ field. Furthermore, its potential has not been fully explored. This study aims to determine the lithological characteristics, facies, and paleocurrents of sandstone reservoirs A, B, and C in the Bekasap Formation, RJ field, Central Sumatra Basin. This study was conducted using a method that integrated log data analysis, core rock description, and dipmeter analysis. This study produced the lithological characteristics of sandstone reservoir A with lithological characteristics of sandstone, kaolinite, white, fine to coarse grain size, and no calcareous content, poor sorting, sandstone reservoir B has interlaminated sandstone lithology characteristics with mudstone, grayish white, medium to fine grain size, does not contain calcareous, hard compactness, good sorting, and sandstone reservoir C has lithological characteristics of sandstone, very silty, clayey, abundant glauconite, gray to light gray, very fine grain size, calcareous structure, good sorting. Sandstone reservoir A has three types of facies, namely tidal bar axis, tidal bar off-axis, and tidal bar margin, while sandstone reservoirs B and C have two types of facies, namely tidal bar off-axis and tidal bar margin. Sandstone reservoirs A, B, and C have a dominant northeast-southwest paleocurrent, with a polymodal flow pattern indicating a tidal bar deposition environment.
