Abstract

Praktikum ini bertujuan untuk menganalisis tingkat produktivitas dan beban kerja operator di Divisi Finishing 2 CV SP Aluminium menggunakan metode pengambilan sampel kerja. Studi ini berfokus pada tiga operator pembubutan dan pemolesan yang terlibat langsung dalam proses finishing produk aluminium. Data dikumpulkan melalui pengamatan acak aktivitas kerja, dengan 50 pengamatan per hari selama enam hari kerja, untuk mengidentifikasi proporsi aktivitas produktif dan non-produktif. Data yang dikumpulkan kemudian dianalisis dengan menghitung tingkat kinerja, melakukan uji kecukupan dan keseragaman data, menentukan faktor penilaian dan toleransi, serta menghitung waktu normal, waktu standar, dan beban kerja operator. Hasil menunjukkan bahwa tingkat produktivitas operator berkisar antara 72% hingga 74%. Sementara itu, nilai beban kerja yang dihitung adalah 110,09%, 114,29%, dan 119,45%, menunjukkan bahwa semua operator mengalami kondisi beban kerja berlebih. Waktu standar terkecil yang diperoleh adalah 3,43 menit per unit, yang ditetapkan sebagai standar referensi untuk menyelesaikan satu unit produk. Berdasarkan temuan ini, diajukan rekomendasi perbaikan, termasuk mengendalikan aktivitas yang tidak produktif, menyesuaikan target produksi berdasarkan waktu standar dan tunjangan, serta menyeimbangkan beban kerja melalui penambahan tenaga kerja. Implementasi rekomendasi ini diharapkan dapat meningkatkan efektivitas pemanfaatan waktu kerja dan meningkatkan produktivitas operator secara berkelanjutan.

Abstract

The amount of waste in urban areas, especially in Yogyakarta City, is growing, which shows the need for better and cleaner waste management. Traditional trash bins need people to touch them directly, which can make them less clean and uncomfortable to use. This study focuses on creating an automatic trash bin that opens and closes without touching, using an ultrasonic sensor. This system is being developed for the Yogyakarta City Environmental Agency (DLH). The system uses an ultrasonic sensor to sense when something is near, a microcontroller to control everything, and a servo motor to open and close the bin automatically. The research process includes reading previous studies, designing the system, building a prototype, and testing how well it works. The test results show that the system can accurately detect objects within a certain distance and operate the opening and closing function smoothly and quickly. Using this automatic trash bin can help make public spaces cleaner, more comfortable for users, and support the development of technology-based waste management solutions in Yogyakarta City.

Abstract

Quality control is a crucial step in the production process. to maintain product quality and improve process efficiency. PT X is still experiencing defect problems in the GM5B cover product produced through the injection moulding process. During the period of March–May 2025, the total production of GM5B covers reached 13,397 pieces, with 1,145 defective products, resulting in a defect rate of 8,55%, which exceeds the company standard of 4%. The Six Sigma method was used to examine these issues utilizing the DMAIC (Define, Measure, examine, Improve, and Control) methodology. The Failure Mode and Effect Analysis (FMEA) method was used to identify possible failures based on the sources of defects. Risk Priority Number (RPN). The results of the analysis over a 12-week period showed an average Defects Per Million Opportunities (DPMO) value of 28,534.17 and an average sigma level of 3.42. According to the Pareto diagram study, the most prevalent type of defect was contamination, accounting for 36.07%. The causes of contamination defects were further identified using a fishbone diagram to determine the root causes. Further analysis using FMEA indicated that the short shot defect has the highest RPN rating of 270, indicating that corrective action should be given top priority. Improvement proposals were developed using the 5W+1H approach, and the control stage was implemented to ensure that the improvements could be carried out consistently and sustainably

Abstract

The phenomenon of cohabitation, defined as living together outside a legally recognized marriage, has increasingly emerged as a social reality alongside shifting relational patterns and value systems in modern society. This development has generated ongoing debates regarding the extent to which the state may legitimately intervene in the realm of private morality through criminal law. This study aims to analyze the regulation of cohabitation within the national criminal law framework, both in the context of the absence of explicit regulation under the former Criminal Code (KUHP) and the implications of morality-based provisions under the new National Criminal Code, as well as to assess the rationality of its criminalization from the perspectives of modern criminal law and human rights. This research employs a normative legal method using statutory, conceptual, and philosophical approaches, drawing upon legislation, criminal law doctrines, and relevant scholarly literature. The findings indicate that the criminalization of cohabitation has the potential to generate tension between public morality and the principle of legality, particularly in relation to the doctrines of ultima ratio, proportionality, and legal certainty. Moreover, overly broad regulatory formulations may create opportunities for abuse of authority and risk infringing upon the rights to privacy and individual freedom. Accordingly, this study recommends that criminal law policy formulation adopt a limited and selective approach to state intervention, oriented toward the protection of concrete legal interests, in order to avoid overcriminalization in the domain of private morality. Keywords: cohabitation, criminal law, morality, legality principle, human rights.
