Abstract

Perkembangan teknologi pembangunan kapal sudah didukung oleh peningkatan kualitas dan juga fasilitas yang memadai untuk melakukan proses produksi. Namun sebagian besar galangan di Indonesia mengunakan cara yang sederhana untuk melakukan proses produksi. Cara ini dikenal dengan strategi non-zero margin (metode dengan memberikan marginal pada setiap proses produksi, dari gambar kerja hingga proses erection pada kapal). Hal ini sangat merugikan dan menimbulkan berbagai permasalahan yang terbagi dari segi management dan juga dalam segi produksi. Permasalahan dari segi management yaitu mengenai JO, biaya (over budget), Re-schedule. Sedangkan permasalahan pada produksi yaitu seperti misalignment (ketidaklurusan), deformasi kompleks, waste matrial. Oleh karena ini, PT. DRU Unit III Lampung berinovasi untuk meminimalisir permasalahan dan kerugian yang ada dengan menerapkan strategi baru yang dinamakan “zero margin”. Strategi ini menerapkan sistem non marginal (tanpa mengunakan margin pada setiap proses) dengan memaksimalkan kinerja dari sistem akurasi kontrol yang berlaku dan sistem management yang lebih terarah. Maka analisis perlu dilakukan pada setiap bagian termasuk fase krusial yang menyebabkan munculnya permasalahan dari proses awal hingga erection pada kapal. Metode analisis observatif dan diterapkan pada proses produksi dan juga menentukan sistem akurasi kontrol yang tepat untuk mendukung program zero margin ini. Pelaksanaan strategi zero margin dengan sistem akurasi kontrol dapat meghasilkan nilai efektifitas dan efisiensi dalam pelaksanaan proses produksi yaitu dapat menghemat biaya produksi, mempercepat target pengerjaan, dan meminimalisir berbagai kesalahan di lapangan.

Abstract

PT Dok dan Perkapalan Surabaya (DPS) is one of several strategic BUMN in marine field. With BUMN restructurisation and efficiency program from Government, PT DPS is liable to improve its production system efficiency. Many problems that faced by PT DPS to improve its production system efficiency are : (1)There is waste work shop such as work in process, waiting time, and flow time at fabrication process in PT DPS, (2) Because waste work shop is still big, shop production process efficiency has not reached maximally yet, (3)Layout and facilities of PT DPS today is already suitable with concept of Product Oriented Work Breakdown Structure (PBWS), but it is limited at simple construction form. At this research, there is ship production process design with Process Lane Construction and Zone Outfitting method or it is known with Group Technology Layout (Manufacturing Cell System) term in order to solve inefficiency problem at ship production process in PT DPS. Design process is performed by integrating Simulation method, Taguchi, Response Surface Methodology, and Analytical Hierarchy Process (AHP). Simulation method is used to model designed manufacturing cell system, meanwhile Taguchi method and Response Surface Methodology are used for experiment and optimization at manufacturing system simulation model. In order to measure the performanceof designed manufacturing cell system, multivariate measurement method is used, that is by measuring work in process, waiting time, and flow time with smaller the better criteria. Multi response becomes single response by using Analytical Hierarchy Process (AHP) method.

Abstract

Corruption in Indonesia is no longer a new legal issue because the problem of corruption has existed for thousands of years, both in developed countries and developing countries, including Indonesia. Today's corruption problem in Indonesia is so severe that it has become an extraordinary problem because it has infected and spread to all levels of society. Corruption crimes in ancient times were regulated in the Criminal Code due to the dynamics that developed in society. The regulation underwent changes where it was special, or lex was then regulated for the first time in Law Number 31 of 1999 jo. Amendment to Law Number 20 of 2001 concerning the Eradication of Corruption Crimes. During its activities, corruption is carried out by the holders of the highest power, who have positions that are mostly the result of election winners in a party. The PTPK Law states that people who commit corruption must compensate the state due to the economic and social impact of a region that it causes on the state's finances. On the way, the addition of prison sentences for heavy corruptors provides a deterrent effect for corruption perpetrators, with which it is hoped that corruption crimes can be reduced

Abstract

Pemilihan Kepala Daerah (Pilkada) Serentak merupakan bagian penting dari proses demokrasi di Indonesia yang memberikan hak kepada masyarakat untuk memilih pemimpin daerah secara langsung. Salah satu aspek yang menjadi perhatian dalam Pilkada adalah penggunaan alat peraga kampanye, yang sering kali melibatkan pelanggaran terhadap ketentuan yang berlaku, baik dari sisi penempatan, ukuran, maupun isi materi kampanye. Penelitian ini bertujuan untuk menganalisis peran Badan Pengawas Pemilu (Bawaslu) dalam penegakan hukum dan pemberian sanksi terhadap pelanggaran penggunaan alat peraga kampanye di Kabupaten Indragiri Hilir. Dengan menggunakan pendekatan kualitatif, penelitian ini menggali pengawasan Bawaslu terhadap pemasangan alat peraga kampanye, serta efektivitas sanksi yang diterapkan terhadap pelanggaran yang terjadi. Hasil penelitian menunjukkan bahwa meskipun Bawaslu telah berperan aktif dalam mengawasi pemasangan alat peraga kampanye, keterbatasan sumber daya manusia dan koordinasi antar lembaga menjadi tantangan utama dalam penegakan hukum. Selain itu, pemberian sanksi yang sering kali hanya berupa peringatan atau penghapusan alat peraga dinilai kurang efektif dalam memberikan efek jera kepada pelanggar. Penelitian ini menyarankan agar Bawaslu memperkuat koordinasi dengan instansi terkait dan mengevaluasi kebijakan sanksi untuk meningkatkan efektivitas pengawasan dan penegakan hukum dalam Pilkada mendatang.
