Abstract

The focus of this research was maintenance and repair of robotic welding technology using preventive maintenance with modular design. This concept organizes machine parts to reduce manufacturing costs, repair procedures, and reduce product defects, as well as minimize component damage such as undercut, overlap, and porosity. If component damage occurs, maintenance/replacement of components is not only carried out on the damaged component but also is connected to other components. The method used in this research was observation carried out by direct observation at the location of the information source at the company Showa Kinzoku.co.,ltd, as well as literature study in order to obtain complementary data and solve problems. This shows that there was a significant decrease in damage after research was carried out before maintenance was carried out in November {13.0}, December {12.3}, January {12.5}. After maintenance was carried out in February {4.12}, March {3.33}, April {3.76} the difference was very significant. In this research the author also looked at seasonal factors, in the winter in December product damage reached {12.5} damage and in the summer in April it decreased to {3.76} damage. Based on the results of the analysis, it can be concluded that the implementation of preventive maintenance with modular design is very effective, the January presentation data showed 77% damage, compared to April's only 23% damage. Maintenance significantly reduces average product defects by more than 50%, demonstrating high effectiveness in this period.

Abstract

Penelitian ini bertujuan memberikan justifikasi akademik terhadap praktik pemboikotan produk non-Muslim dengan menegaskannya dalam kerangka normatif hukum Islam. Surah al-Mumtahanah (Q.S. 60: 8–9), yang sering dipahami sebagai ajakan toleransi, ternyata memuat dua orientasi etis: ayat 8 membuka ruang kebajikan bagi non-Muslim yang tidak memusuhi, sementara ayat 9 memberikan batas tegas terhadap pihak yang menunjukkan permusuhan. Melalui kajian tafsir klasik dan analisis us}u>l al-fiqh, penelitian ini menemukan bahwa ‘illat al-hukmi pada ayat 9 memberikan dasar normatif bagi pemboikotan sebagai bentuk menghindari kerja sama yang bertentangan dengan prinsip syariat. Menggunakan metode kualitatif berbasis studi pustaka dengan sumber primer berupa kitab tafsir dan literatur uṣūl al-fiqh, serta sumber sekunder berupa karya ilmiah, data dianalisis melalui model Huberman dan Miles. Hasil penelitian menegaskan bahwa kedua ayat tersebut membentuk etika Islam yang proporsional—toleran kepada non-Muslim yang damai, namun tegas terhadap pihak yang memusuhi—sehingga dapat menjadi landasan yang sah bagi pemboikotan dalam konteks kontemporer
