Abstract

Wilayah Hargosari terletak di daerah karst Gunungsewu yang dikenal sebagai daerah subur dan kurang air terutama selama musim kemarau. Secara geologis, tersusun oleh batu gamping yang berpotensi menyebabkan sungai bawah tanah sebagai akibat dari proses pelarutan. Metode VLF-EM digunakan untuk mengetahui pola sungai bawah tanah terkait dengan kontras parameter fisik konduktif yang disebabkan oleh keberadaan air di lubang batugamping. Tujuan dari penelitian ini adalah untuk menentukan jejak dan pola sungai bawah tanah Bribin serta pemodelannya menggunakan perangkat lunak lnv2DVLF. Interpretasi kualitatif dilakukan berdasarkan pada pengolahan data yang telah dikoreksi topografi menggunakan filter moving average dan filter Karous-Hjelt, sedangkan interpretasi kuantitatif menggunakan program lnv2DVLF dan divisualisasikan menggunakan Surfer 12. Berdasarkan interpretasi kualitatif dan kuantitatif, dapat disimpulkan bahwa sungai bawah tanah Bribin mengalir dari arah timur ke barat melalui wilayah Hargosari, dan terdiri dari dua aliran sungai bawah tanah yang saling berhubungan. Lebar area konduktif adalah (25 ± 5) m pada kisaran kedalaman sekitar 148-184 m.

Abstract

Indonesians have different backgrounds; they can live in harmony and side by side without any friction and conflict due to cooperation between religions in an excellent multicultural frame. The research approach is library research. The primary data source used is the Qur'an with the thematic method, while secondary data is in books, journals, and documentation. The study findings show; (1) the cooperation verses in the Qur'an, fifteen verses have the Madaniyah status, and seven verses have the Makiyah status. These verses are grouped into three things: cooperation based on Islamic brotherhood, cooperation based on ukhuwah wathaniyah or nationality, and cooperation based on ukhuwah basyariah human-based. Somebody can carry out a partnership based on ukhuwah basyariah in a multicultural context can be carried out in the political, economic, cultural, and social fields. (2) The hadiths related to the cooperation verses are found in Sahih Muslim numbers 2704 and 2705, Sahih Bukhari numbers 2124 and 2811, Sunan Nasai numbers 3867 and 3871. Based on the transmission line, the hadith is agreed to be a valid hadith even though there are differences in the text, but the meaning has the same substance.

Abstract

Hidrokarbon dapat berpindah dari batuan induk menuju ke reservoar bahkan dari reservoar ke reservoar yang lain melalui sesar. Proses tersebut biasa disebut sebagai migrasi hidrokarbon. Tidak semua sesar dapat menjadi jalan migrasi hidrokarbon, hal ini bisa dilihat dari karakteristik sesar itu sendiri yaitu penerus (leaking) atau penyekat (sealing). Cekungan Sumatera Selatan merupakan area dengan kondisi geologi yang kompleks. Terdapat dua sesar yang menghubungkan antara dua sumur minyak dan gas. Dalam penentuan karakter dua sesar tersebut maka dilakukan analisa sekatan sesar berdasarkan perhitungan shale gouge ratio (SGR) pada lapangan “IAD” cekungan Sumatera Selatan dengan formasi Baturaja Ekivalen (BRF EQV) sampai Upper Basement (TBT). Hasil analisa sekatan sesar pada kedua sesar lapangan tersebut menunjukkan bahwa sesar-4 bersifat sealing dengan nilai SGR sebesar 39% pada kedalaman (MD) 2215,42 – 2345 meter dengan kemiringan 75o dan sesar-5 bersifat leaking dengan nilai SGR sebesar 19,6% pada kedalaman (MD) 2190 – 2241,36 meter dengan kemiringan 80o. Kata kunci: Sekatan Sesar, SGR, sealing, leaking.

Abstract

Bangka Island is on the Sunda Shelf (Eurasian tectonic plate) and the outer part of the Sumatra basin. Plate tectonic activity results in fault structures and forms the statigraphy of rock formations such as Alluvium, Ranggam, Klabat Granite, Tanjung Genting, and the Pemali Complex. The fault structure was identified as a control structure for the radiogenic geothermal system. Radiogenic geothermal heat originates from the decay of radioactive elements in granite rocks (Klabat Granite formation) on Bangka Island. The purpose of this research is as a preliminary survey of the presence of Slag and Cracker geothermal energy on Bangka Island using the gravity method. The research data used is secondary data obtained from the Topex satellite (Topography Experiment). The results of the modeling show that many fault structures in the study area are found around the Slag and Cracking geothermal manifestations. The fault structure is also accompanied by a breakthrough by the lower layer of rock into the rock above it. So that the fault structure can control the Slag and Crack radiogenic geothermal system.

Abstract

PT Great Giant Pineapple (GGP) is the 3rd largest pineapple producer in the world. The cultivationactivities carried out by PT Great Giant Pineapple (PT GGP) still use a conventional system. PT. GGPdoes not yet have facilities and infrastructure that support the development of plant cultivation with ahydroponic system so that cooperation with Politeknik Negeri Lampung (Polinela) is needed in itsdevelopment. The problems faced by PT GGP, especially in the Research & Development section,can be resolved by conducting counseling on hydroponic drip irrigation methods for fruit, especiallymelon plants. By holding hydroponic counseling activities on drip irrigation methods for fruit at PTGreat Giant Pineapple, it is hoped that it can increase the knowledge and understanding of workersand staff at PT GGP on the cultivation and installation of hydroponic drip irrigation methods on melonplants. So that the development of hydroponic melon cultivation techniques with drip irrigationmethods can be carried out independently by partners.

Abstract

This study aims to evaluate the growth and vitamin C content of red amaranth microgreens (Amaranthus tricolor) under various nutrient concentrations and growing media. The experimental design used in this study was a Randomized Complete Block Design arranged factorially 5 x 3 (15 treatments) with 3 repetitions. The first factor was the concentration of hydroponic nutrients at levels of 0 ppm, 100 ppm, 200 ppm, 300 ppm, and 400 ppm. The second factor was the combination of growing media, namely sand + sawdust, sand + rice husk charcoal, and sand + cocopeat, with a 1:1 ratio for each combination. Data obtained from the observed variables were analyzed using variance analysis and further tested with an LSD test at a 5% significance level. The observed parameters included germination rate (%), plant height (cm), number of leaves, leaf color, root length (cm), number of roots, plant weight (mg), and vitamin C content. The results showed that the use of sand + rice husk charcoal as a growing medium was very suitable for the germination of red spinach microgreens. However, for leaf color and root length, the use of sand + cocopeat was better. The sand + cocopeat medium combined with nutrient concentrations of 300 ppm and 400 ppm produced the best plant height and sample weight compared to other treatments. Furthermore, the sand + sawdust medium was very effective in producing the number of roots and the vitamin C content of red spinach microgreens.
