Abstract

Mesin press hydraulic limbah SBE digunakan untuk menekan limbah SBE untuk memisahkan kandungan minyak yang tersisa didalam SBE tersebut. Pengoperasian mesin secara berkelanjutan dan tiadanya penerapan perawatan pencegahan membuat komponen mesin press hydraulic mengalami kerusakan antara pompa, seal hydraulic, screw conveyor, bearing dan lagher gantung, serta komponen semi-kritis lainnya. Penentuan perawatan pencegahan mesin dilakukan dengan menggunakan metode Reliability Centered Maintenance (RCM) yang meliputi pembatasan sistem, diagram pareto kerusakan, FMEA dan LTA dengan tujuan untuk menentukan interval waktu penggantian komponen kerusakan terpilih untuk memberikan gambaran total downtime yang dibutuhkan dalam melakukan tindakan perawatan tersebut. Hasil dari penelitian ini menyimpulkan bahwa tindakan yang terpilih dari setiap kerusakan komponen dikategorikan sebanyak 12 komponen untuk tindakan Condition Directed (CD) dengan persentase sebesar 66,67%, 2 komponen untuk tindakan Time Directed (TD) dengan persentase sebesar 11,11% dan 4 komponen untuk tindakan Failure Finding (FF) dengan persentase sebesar 22,22%.Pengantian komponen hanya terjadi pada komponen seal hydraulic dengan interval waktu pengantian terjadi pada hari ke-72 dengan nilai laju kerusakan sebesar 0,007106 serta total downtime sebesar 0,011844, dan komponen bearing dengan interval waktu pengantian komponen terjadi pada hari ke- 42 dengan nilai laju kerusakan sebesar 0,012680 serta total downtime sebesar 0,056931

Abstract

The open mining method has the potential for the formation of mine water. Mine water is characterized by a high degree of acidity which affects the life of organisms and the quality of the environment indirectly or directly, therefore it needs to be managed. This study examines mine water management at PT Adaro Indonesia. The methods used in the research were field studies and laboratory experiments. Grab sampling is used to take water samples, with the test parameters being pH, Fe and Mn metals and total suspended solid (TSS). Data analysis was carried out quantitatively and descriptively. The mine water management used is in the form of a settling pond. The settling pond consists of several compartments, namely sedimentation pond, safety pond, treatment pond and mud pond. The quality of mine water management through a series of settling ponds obtained changes in pH to 6.07, Fe metal 0.0465 mg/l, Mn metal 1.3513, and TSS 35 mg/l with an efficiency of more than 50%. The quality of mine water produced after going through management has met the established regulations, namely Decree of the Minister of Environment and Forestry No. 1347/MENLHK/SETJEN/PLA.4/12/2022.

Results of this study show that Nahdlatul Wathan Diniyah Islamiyah Islamic education's existence in terms of education meaning has undergone evolution/development as a continuum of meaning when history first occurred, present, and future. The historical phenomenon shows that apart from establishing a men's Islamic education (Nahdlatul Wathan), figures (founders) also founded a women's Islamic education (Nahdlatul Banat). Nahdlatul Wathan is a social organization engaged in fields of education, social, and Islamic da'wah and adheres to Islam ahlusunnah wal jama'ah.

Abstract

This study examines the relevance of textual and contextual approaches in understanding the message of the Qur’an through a comparative study. The textual approach emphasizes the literal meaning and linguistic structure of the verses, while the contextual approach considers the historical, social, and cultural dimensions surrounding the revelation. Using a qualitative method based on literature review, this study analyzes primary and secondary sources relevant to Qur’anic exegesis. The findings indicate that the contextual approach offers a more responsive understanding of contemporary issues, whereas the textual approach is essential to preserve the integrity and purity of the Qur’anic message. The integration of both approaches is proposed as an ideal model for interpreting the Qur’an comprehensively and contextually. This article contributes to the development of Qur’anic exegesis methodology that is adaptive to modern social dynamics.Keywords: Qur’anic Interpretation; Textual Approach; Contextual Approach; Comparative Study

Abstract

In South Sulawesi, justice in polygamy is not merely a matter of law—it is a living dialogue between divine principles and ancestral wisdom. This study explores how local wisdom, particularly the adat system, serves as a foundational pillar of justice in the practice of polygamy under Islamic law. Employing a qualitative methodology, the research draws on interviews and document analysis involving religious leaders, community elders and affected families. The findings reveal that while Islamic law provides the formal legal framework, local customs deeply influence its interpretation and implementation. Adat norms ensure that polygamy is practiced with fairness, emphasizing the equitable treatment of wives, fulfillment of economic responsibilities and preservation of familial harmony. These traditions act as a moral compass, guiding the community to uphold justice in ways that resonate with their social values. Rather than conflicting with Islamic principles, local wisdom complements them—creating a hybrid system that is both legally sound and culturally sensitive. The study concludes that integrating local wisdom into formal legal structures can enhance the contextual relevance and social legitimacy of family law. It recommends a pluralistic approach to justice that honors both religious doctrine and indigenous knowledge, fostering a more humane and balanced legal practice.
