Abstract

Penelitian ini bertujuan untuk mengevaluasi konsumsi bahan bakar alat angkut Double Trailer K500 Renault terhadap produktivitas pada operasi hauling PT Kumala Bahtera Utama. Pengamatan dilakukan selama 20 hari untuk memperoleh data operasional harian mencakup konsumsi bahan bakar, produktivitas, serta fuel ratio (liter/ton). Hasil pengamatan menunjukkan bahwa rata-rata produktivitas aktual adalah 18,33 ton/jam, lebih rendah dari target rencana sebesar 22,67 ton/jam. Sementara itu, rata-rata fuel ratio yang diperoleh sebesar 0,72 liter/ton, yang digunakan sebagai tolok ukur efisiensi konsumsi bahan bakar. Tingginya cycle time dan lost time terbukti berpengaruh negatif terhadap efisiensi pengangkutan dan produktivitas alat. Efisiensi terbaik dicapai saat fuel ratio rendah dan tidak terdapat gangguan operasional. Berdasarkan temuan ini, disarankan agar perusahaan melakukan optimalisasi jadwal operasional, meningkatkan kualitas perawatan alat, serta memberikan pelatihan bagi operator guna mendukung peningkatan efisiensi konsumsi bahan bakar dan produktivitas hauling.

Abstract

Penimbunan batubara merupakan salah satu tahapan penting dari kegiatan penanganan batubara (coal handling). Apabila sistem penimbunan kurang memadai maka dapat mengganggu kegiatan pembongkaran timbunan batubara di tempat penimbunan, terutama batubara bersifat mudah terbakar dengan sendirinya. Penelian ini bertujuan mengkaji teknis pengolahan dan pola penimbunan batubara di PT. semen baturaja (persero)tbk. Metode penelitian yang digunakan pada penelitian ini ialah menggunakan penelitian dan pengamatan langsung terhadap kondisi dan keadaan di lapangan serta kegiatan/aktivitas penimbunan, pengolahan batubara, kemudian dilakukan pengumpulan data. Data penelitian meliputi data primer yaitu ukuran batubara yang masuk dalam stockpile, proses pengolahan batubara dan desain stockpile dan data sekunder yaitu data proses pengolahan batubara dan data penunjang pengolahan batubara. Hasil kajian teknis dari penelitian ini adalah keberhasilan proses pengolahan batubara selain dari segi kuantitas juga ditinjau dari kualitasnya, yaitu kadar air dan kehalusan fine coal produk coal mill standar air maksimal 9%, agar tidak merugikan proses pembakaran, sedangkan kehalusan batubara dibatasi maksimum 20% yang lolos ayakan 90 µ. Pola penimbunan batubara pada stockpile batubara di PT. Semen Baturaja (Persero) Tbk. Menggunakan pola gundukan bertumpuk dengan ketinggian tidak melebihi belt stacker yang dimaksudkan agar jatuhan material pada lereng tumpukan tidak keluar dari zona penimbunan. Kualitas rata-rata batubara pada raw coal memilikii kadar air 12,54%, screen 30 mm, fly ash 3,7%.

Abstract

Purpose-This study aims to explore the use of uslūb muqābalah in Surah Al-Lail by combining the classical badī' approach and the theory of relevance of modern cognitive linguistics. The beauty of muqābalah will be difficult to understand by those who do not understand the meaning of the Qur'an because its charm lies in the depth of the meaning of its verses.  Design/Methodology/Approach- The research uses qualitative discourse analysis based on literature studies and contextual interpretation of muqābalah verses. The focus of the study is the process of pairing opposing meanings forming rhetorical structures and cognitive devices in the delivery of implicit messages. Findings—The results of the study show that the pattern of couples in Surah Al-Lail, such as night and day, giving and file, strengthens aesthetic beauty while optimizing the relevance of meaning. The principle of optimal relevance encourages the inferential drawing of moral conclusions with minimal cognitive effort. Research Limitation/Implications- This research is limited to Surah Al-Lail and does not compare it with other suras. However, this study contributes to developing an interdisciplinary approach between balāghah and pragmatic linguistics, which is useful for innovation in the teaching of tafsir and Arabic.

Abstract

Coal quality analysis is increasingly important considering the increasing global energy demand. Coal, as the main source of energy, has varying qualities, affecting combustion efficiency and environmental impact. Two commonly used analysis methods are proximate analysis and ultimate analysis, which provide information about the composition of coal. Previous research has shown that chemical analysis affects energy efficiency and environmental impact. This study aims to analyze the quality of coal using both methods and evaluate its characteristics for industrial applications. The benefits of this research include guidance for coal producers and users, as well as contributions to reducing the environmental impact and sustainability of the energy sector. This study uses a descriptive approach with qualitative and quantitative methods, focusing on Seam E coal at PT Bukit Asam Tbk. Primary data includes coal handling, temperature, and quality, while secondary data includes location maps and rainfall data as a reference. This study resulted in the conclusion that 1) Factors that affect the decline in coal quality at mining sites and stockpiles include the mining process, working front conditions, loading, processing in the stockpile, sampling, and handling in the ROM to Jetty SDJ. 2) Efforts made include contamination avoidance, fine coal handling, stacking management, and blending process.

Abstract

Penelitian ini dilatarbelakangi oleh adanya ketidakseimbangan produktivitas antara alat muat dan alat angkut yang berpotensi menghambat pencapaian target ritase pengangkutan batubara di PT Kumala Bahtera Utama. Tujuan penelitian adalah untuk menganalisis keserasian operasional antara Wheel Loader Volvo L350H dan Double Trailer Renault K500 dalam mencapai target produksi, dengan mengukur produktivitas, waktu edar (cycle time), dan faktor keserasian (match factor). Metode yang digunakan adalah penelitian kuantitatif dengan observasi lapangan langsung selama 20 hari untuk mengumpulkan data primer berupa produktivitas, cycle time, dan kondisi operasional, yang selanjutnya dianalisis menggunakan perhitungan produktivitas dan match factor. Hasil menunjukkan ketidakseimbangan kerja dengan nilai match factor 1,58, yang menyebabkan waktu tunggu pada alat angkut dan menurunkan efisiensi produksi sebesar 28,5% dari target perusahaan. Solusi yang direkomendasikan adalah penambahan satu unit wheel loader standby untuk mencapai match factor ideal mendekati 1,0, yang diharapkan dapat meningkatkan efisiensi operasional hingga 35% dan mengurangi biaya idle time alat angkut. Kontribusi utama penelitian ini adalah penyediaan model optimasi keserasian alat berbasis data empiris yang dapat diaplikasikan pada operasi pengangkutan batubara dengan karakteristik jarak tempuh panjang dan kondisi jalan berkerikil.

Abstract

Clinical learning is a process of interaction between clinical preceptors and students as learners on the practice field. The clinical guidance process is often limited to supervising nursing students during clinical practice without any targets that need to be achieved, even students repeat the same activities every day. This study aims to determine the application of a target-based clinical learning model in improving the quality of preceptors. The study used a quasi-experimental design with a one group time series design on 40 nurses from several hospitals and educational institutions who had not received clinical preceptor training. The sampling technique used quota sampling technique according to the proportion of the number of students who were practicing in their respective institutions, the sample was given an intervention in the form of training using a target-based clinical learning model consisting of theory and practice. The practice was conducted in the laboratory and in the hospital from September to December. Evaluation using a checklist instrument for assessing preceptor competence and data analyzed using the Wilcoxon test using SPSS 25.0.  The result of the study, there was a significant increase in the ability of nurses to provide nursing clinic preceptors between before and after training with a significance value of 0.020, while in the first supervisory assessment significant=0.030, second supervision significant=0.040 and third supervision significant=0.050. The data shows how closely the target-based learning model affects the quality of clinical supervisors' abilities. This is important to be applied to all prospective clinical supervisors before conducting clinical guidance.
