Abstract

PT ISPAT Indo, produsen baja wire rod, menghadapi tantangan dalam menjaga kualitas produk di era persaingan industri yang ketat. Pengendalian kualitas (QC) menjadi prioritas untuk meminimalisir kecacatan dan meningkatkan kepercayaan konsumen. Dengan menerapkan metode Six Sigma, perusahaan melakukan analisis terhadap cacat produk yang terjadi, seperti rolling defect yang mencapai 298 ton. Hasil pengukuran menunjukkan nilai DPMO (Defects Per Million Opportunities) sebesar 485, dengan level sigma 5, menandakan bahwa variasi dan cacat produk telah diminimalkan. Analisis penyebab cacat menggunakan diagram fishbone mengidentifikasi faktor-faktor seperti mesin, metode, material, dan manusia sebagai penyebab utama. Langkah perbaikan yang diambil mencakup peningkatan standar pemilihan pemasok bahan baku, pelatihan intensif bagi pekerja mengenai prosedur operasi standar (SOP), serta penerapan sistem pemeliharaan preventif pada mesin. Dengan upaya ini, PT ISPAT Indo berkomitmen untuk mencapai zero defect dalam proses produksi dan meningkatkan kualitas produk secara keseluruhan.

Abstract

This study aims to analyze the strategic role of the principal as an educational supervisor in improving the sustainable quality of teaching and learning at Tabgha Mulia School, Batam. The main focus is on implementing academic supervision through a collaborative and reflective leadership style. The study method used is a descriptive qualitative approach. Data were collected through in-depth interviews, direct observations, and document analysis. The data analysis technique used is the Miles and Huberman model, which consists of data reduction, data display, and conclusion drawing. The results show that the principal’s leadership, which emphasizes collaboration, reflection, and mentoring, positively contributes to improving teacher professionalism, particularly in lesson planning, reflective thinking, and participation in quality development programs. However, several challenges were identified, including the lack of preparedness of instructional materials and unexamined teaching routines. It is concluded that effective academic supervision requires a substantive and contextual approach, along with the principal’s role as a facilitator in fostering an eval_uative culture within the school environment. The implication of this research highlights the importance of strengthening the principal’s capacity in conducting pedagogical supervision to achieve adaptive and sustainable teaching and learning quality

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengevaluasi kontribusi implementasi ISO 45001 terhadap peningkatan keselamatan dan kesehatan kerja (K3), mengidentifikasi tantangan yang dihadapi, serta merumuskan strategi optimalisasi penerapannya di berbagai sektor industri. Metode penelitian yang digunakan adalah literature review sistematis terhadap 20 jurnal ilmiah terbitan tahun 2019 hingga 2025, dengan seleksi berbasis kriteria inklusi dan eksklusi tertentu. Hasil penelitian menunjukkan bahwa penerapan ISO 45001 memberikan dampak signifikan dalam menurunkan angka kecelakaan kerja, meningkatkan kepatuhan terhadap regulasi, serta membentuk budaya keselamatan yang lebih kuat di tempat kerja. Metode identifikasi risiko seperti HIRARC, JSA, dan FTA terbukti efektif dalam klasifikasi dan pengendalian potensi bahaya kerja di berbagai sektor, termasuk konstruksi, manufaktur, kesehatan, dan administrasi. Namun, tantangan implementasi seperti tingginya biaya, resistensi terhadap perubahan budaya kerja, dan keterbatasan sumber daya manusia masih menjadi hambatan, terutama di sektor usaha kecil dan menengah (UKM). Kesimpulannya, untuk mengoptimalkan implementasi ISO 45001 secara berkelanjutan dan adaptif, diperlukan komitmen manajemen, partisipasi pekerja, serta dukungan kebijakan dan pelatihan teknis yang berkesinambungan.   Kata Kunci : Keselamatan dan Kesehatan Kerja (K3), Manajemen Risiko, Industri Konstruksi dan Manufaktur

Abstract. The waiver of a case is an authority, it is not impossible that the decision to waive a case can be challenged in court, to question whether in carrying out the duties and authority of the case deponeer, the Attorney General has sufficient reasons, namely: To what extent does the waiver of the case meet the requirements for the sake of public interest, namely the interests of the nation and state and/or the interests of the general public and the ideal measure of the use of the opportunity principle and which is able to provide a picture of the prosecution policy in handling criminal cases effectively, efficiently, and responsibly which is carried out without abandoning the sense of justice. The aim of this research is to find out and analyze (1) the nature of the position of the Prosecutor in the Indonesian Criminal Justice System, (2) the legal barometer of the Prosecutor's authority to set aside cases in the criminal justice process, and (3) the fundamental problems of the Prosecutor's authority to set aside criminal cases. The approach method used in this study is normative juridical. The specifications of this study are descriptive analytical. The data source used is secondary data. Secondary data is data obtained from library research consisting of primary legal materials, secondary legal materials and tertiary legal materials. The research results and discussion can be concluded: (1) In the criminal justice system, the role of the prosecutor's office is very central because the prosecutor's office is the institution that determines whether a person should be examined by the court or not. The prosecutor also determines whether a person will be sentenced or not through the quality of the indictment and charges made. (2) Article 35 letter c of Law Number 11 of 2021 concerning Amendments to Law Number 16 of 2004 concerning the Attorney General's Office of the Republic of Indonesia is the legal basis for setting aside cases in the public interest as the authority of the Attorney General. The setting aside of cases in the public interest based on Constitutional Court Decision Number 29/PUU-XIV/2016, can be carried out after the obligation to pay attention to the advice and opinions of state authorities that have a relationship with the problem is carried out by the Attorney General. (3) The issuance of a deponeering decision is a debate in Indonesia both among academics and among state institutions. The debate occurs because of the diversity of opinions or it can be said that for multiple interpretations of the meaning of "public interest" to be applied in a case.

Abstract

Artikel ini membahas perancangan dan evaluasi kinerja sistem pendingin cairan pada unit controller shuttle bus listrik hasil konversi. Permasalahan termal pada kendaraan listrik hasil konversi, khususnya pada komponen controller, menjadi tantangan serius yang dapat menurunkan efisiensi dan memperpendek umur pakai sistem. Evaluasi dilakukan melalui perbandingan eksperimental terhadap suhu dan efisiensi controller. Pengujian dilakukan dalam dua kondisi: sebelum dan sesudah menggunakan sistem pendingin, pada variasi kecepatan kendaraan antara 20 hingga 50 km/jam. Alat yang digunakan antara lain, dynamometer, Hioki Power Analyzer, dan thermometer infrared. Hasil penelitian menunjukkan penurunan suhu kerja sebesar 2,4-4,3°C dan peningkatan efisiensi controller sebesar 2,76-4,37%. Grafik efisiensi dan suhu menunjukkan perbedaan signifikan antara dua kondisi yang menunjukkan efektivitas sistem. Kesimpulannya, sistem pendingin cairan terbukti efektif dalam meningkatkan performa termal dan efisiensi controller pada shuttle bus listrik hasil konversi. Studi ini memberikan kontribusi praktis dalam pengembangan sistem manajemen termal kendaraan listrik berbiaya rendah dan merekomendasikan eksplorasi lebih lanjut terkait pengujian statistik untuk validasi hasil yang lebih kuat.
