Abstract

ABSTRACT Well water is a source of water that is used by the community around the landfill for everyday life. The well water is not far from the landfill site. Based on observations the environment around the TPA is very dirty and there are puddles of water, so it is not good for residents who are around TPA to use well water for their daily lives. Some simple methods can be done to determine the condition of well water, one of which is by simple physical and chemical testing. Simple physics tests are carried out by looking at changes in color, turbidity, and odor while chemical tests are carried out by mixing sample solutions with tea. In the physical and chemical test of the well water of the residents around the TPA 2 in Palembang, it can be concluded that the well water around the TPA has a cloudy color, a strong odor and a pH of 7.

Abstract

PERTAMINA (Persero) RU III Plaju-Sungai Gerong is a processing unit owned by PT. PERTAMINA. One of the units found at PT. PERTAMINA RU III Plaju, a unit of Residue Fluid Catalytic Cracking Unit (RFCCU), which is located in the Crude Distiller and Light Ends (CD & L) section, which is part of the processing and production of petroleum. Reliability of operation on the Reactor and Regenerator at the RFCCU is one of the determining factors for further processes in the next unit. This study aims to determine the operating conditions of Reactors and Regenerators that are good in order to achieve the desired product and know about the problems found in the Reactor and Regenerator. Based on reactor temperature specification data, which is 515-590ᵒC and the reactor pressure specifications are 1.5-1.69 kg/cm2, while the regenerator temperature specifications are 676-770ᵒC and the regenerator pressure specifications are 1.4-190 kg/cm2. The temperature and pressure on the reactor and regenerator, 11-25 July 2018 are still within the internal limits of the catalytic cracking process. The average reactor temperature is 506.7ᵒC and the reactor pressure is 1.47 kg/cm2, while the temperature of the regenerator is 677ᵒC and the regenerator pressure is 1.31 kg/cm2. In this study, to get a good operating condition of the reactor and regenerator, it must be considered in the addition and withdrawal of the catalyst continuously in order to maintain the activeness of the catalyst to the feed. Keywords: Catalyst Silica Alumina; Catalytic cracking; Reactor and Regenerator.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas penerapan manajemen peserta didik dalam meningkatkan kedisiplinan siswa berdasarkan tata tertib yang berlaku serta mengidentifikasi bentuk pelanggaran yang masih muncul di SMAN 1 Muaro Jambi. Penelitian ini menggunakan metode deskriptif kualitatif dengan Teknik pengumpulan data berupa wawancara semi terstruktur, observasi non partisipatif dan studi dokumentasi. Informan penelitian terdiri dari Wakil Kepala Sekolah Bidang Kesiswaan, 2 guru, dan 4 siswa. Observasi dilakukan terhadap Pelaksanaan Tata Tertib Sekolah, mekanisme pengawasan kedisiplinan, serta prosedur penanganan pelanggaran, sedangkan dokumentasi meliputi buku tata tertib sekolah, serta catatan pelanggaran siswa. Hasil penelitian menunjukan bahwa implementasi manajemen peserta didik di SMAN 1 Muaro Jambi berjalan efektif melalui penerapan sanksi berjenjang, pengawasan  guru yang konsisten, penegakan aturan jam masuk sekolah, serta dukungan Masyarakat dan tokoh adat. Namun demikian, pelanggaran seperti keterlambatan masuk sekolah, membawa telpon genggam tanpa izin, merokok, dan beberapa kasus perkelahian masih ditemukan. Penelitian ini menyimpulkan bahwa tata tertib sekolah telah di terapkan dengan baik, namun diperlukan peningkatan pengawasan pada area rawan pelanggaran, serta pelibatan aktif siswa untuk menjaga kedisiplinan secara berkelanjutan.
