Abstract

A good quality control system is important to be implemented to increase productivity and minimize defects in products. One of the quality control methods is failure mode and effect analysis (FMEA). This study uses the FMEA to identify the causes of the defects and recommend the prevention methods to overcome the causes of the defects in an Indonesian paper mill. The risk priority number (RPN) is calculated by multiplying the severity, occurrence, and detection of the failures that have been determined. Unsymmetrical and tainted products are the most dominant defects in the paper mill. An inappropriate machine setting is the cause of unsymmetrical products with the highest RPN of 343. The second highest RPN is problems with bleaching machines that caused tainted products with an RPN value of 216. This study offers suggestions to Indonesian paper mill to prevent and minimize defective products.

Abstract

Perkembangan teknologi dan globalisasi meningkatkan persaingan pada industri manufaktur. Agar dapat bertahan dalam persaingan bisnis, perusahaan manufaktur harus memenuhi permintaan dan memuaskan pelanggan dengan meningkatkan produktivitas dan efisiensi. Produktivitas dan efisiensi dapat ditingkatkan dengan mengurangi lead time. Lean manufacturing telah terbukti dapat meningkatkan produktivitas dan efisiensi dengan mengurangi lead time dari proses produksi. Studi ini bertujuan untuk meluaskan pemahaman tentang bagaimana lean manufacturing dapat mengurangi lead time dan memahami tantangan yang mungkin muncul. Lead time dari proses produksi dapat dikurangi dengan menggunakan bantuan pendekatan diagram SIPOC, peta aliran proses, penghitungan takt time, model evaluasi pemborosan, dan kuesioner evaluasi pemborosan. Namun, penerapan lean manufacturing untuk mengurangi lead time akan menjadi tidak efektif apabila perusahaan tidak siap dalam hal pengelolaan manajemen sumber daya, manejemen manusia, dan standardisasi.

Abstract

E-government has been a global trend in the world. Many countries around the world have implemented E-government since it is believed could give substantial benefits to citizens, businesses, and governments. The aim of e-government is to support the modernization of the public sector, enabling its transparency and effectiveness. With regard to these significant outcomes, e-government could streamline the economic and social development of a nation, including Indonesia. This paper aimed to review the literature on e-government implementation and its future perspective in Indonesia. The inclusion criteria were e-government trends around the world, application of e-government in Indonesia, the factors and the impact of e-government. This study revealed the critical factors that could affect the implementation of e-government in Indonesia. In addition, e-government has a potential to increase transparency, citizen engagement, and gross domestic product (GDP) growth in Indonesia.

Abstract

Metode pengajaran berbasiskan science, technology, engineering, arts, and mathematics (STEAM) semakin banyak digunakan karena dipercaya mampu membangun kemampuan berpikir kritis pada siswa. Namun, metode ini masih cukup baru di Indonesia. Pengabdian masyarakat ini bertujuan untuk memperkenalkan metode STEAM kepada para siswa kelas 1 sampai 3 di Madrasah Ibtidaiyah Istiqomah Kabupaten Bogor. Metode participatory action research (PAR), di mana siswa diberikan penjelasan, melakukan praktikum, dan berdiskusi secara langsung digunakan dalam pengabdian masyarakat ini. Hasil dari diskusi setelah praktikum menunjukkan bahwa siswa sangat antusias dalam belajar menggunakan metode STEAM. Para siswa merasa bahwa metode STEAM sangat membantu mereka memahami materi pembelajaran. Hal ini mengindikasikan bahwa pengabdian masyarkat berjalan sukses dan bermanfaat bagi para siswa.

Abstract

An increase in productivity is one of the measures of development in a company. High productivity could increase revenue and profit that can be used to further develop the company. This study was conducted in PT XYZ, one of the biggest coal mining companies in East Kalimantan. The aim of this study was to analyze the productivity of excavators and dump trucks using overall equipment effectiveness (OEE). Based on the calculation, the actual availability and quality of both loading and hauling equipment exceed the targeted values. However, the actual performance is lower than the target. As for the OEE values, all of the equipment have lower actual OEE except Hitachi EX-2500. The lowe OEE values might happen because of bad weather, machine breakdown, and a long queue in the mining area. Based on the analysis results, it is recommended that the company increase the availability, performance, and quality of equipment with the high deviation between actual and targeted values.

Abstract

University students working and studying at the same time for various reasons. The aim of the study is to review the impact of students’ dual role as students and workers on the depression rate of working university students in Batam, Indonesia. A comprehensive review of the literature revealed that working while studying does not necessarily affect students’ academic performance. However, depression is the most common health problem in university students. However, working students tend to have higher depression rate than non-working students. Depression in students may be the cause of the high dropout rate in Batam. It is important to administer depression-prevention intervention as early as possible, since the first- and second-year students are the most likely to get depressed Beragam alasan melatarbelakangi mahasiswa bekerja selama berkuliah. Penelitian ini mengulas dampak peran ganda sebagai mahasiswa dan pekerja kecenderungan depresi pada mahasiswa bekerja di Batam, Indonesia. Ulasan komprehensif dari literatur dan observasi langsung menunjukkan bahwa bekerja sambil berkuliah tidak mempengaruhi kinerja akademis mahasiswa. Meskipun demikian, mahasiswa bekerja cenderung memiliki tingkat depresi yang lebih tinggi daripada mahasiswa yang tidak bekerja. Depresi pada mahasiswa dapat menjadi penyebab tingginya tingkat dropout di Batam. Melakukan intervensi pencegahan depresi pada mahasiswa sedini mungkin merupakan hal yang sangat penting dikarenakan mahasiswa tingkat pertama dan kedua adalah yang paling rentan terhadap depresi.

Abstract

Pandemi COVID-19 yang melanda seluruh penjuru dunia menyebabkan semua orang menghabiskan waktu lebih banyak di rumah dengan bermain game. Salah satu game yang menjadi sangat populer selama masa karantina khususnya di kalangan anak muda adalah Among Us. Game ini dianggap mampu menggantikan bentuk sosialisasi dengan teman. Tujuan dari penelitian ini adalah untuk mengevaluasi apakah aplikasi mobile dari Among Us sudah sesuai dan mudah dipahami oleh pengguna. Sebanyak dua puluh partisipan mengikuti eksperimen usability dengan metode kuesioner system usability scale (SUS). Terdapat 4 desain dari interface yang berupa 1 interface dari aplikasi original dan 3 modifikasi diujikan dalam penelitian ini. Hasil dari analisis menunjukkan bahwa aplikasi original sudah sesuai dan dapat diterima oleh pengguna, namun modifikasi dari aplikasi memberikan nilai SUS rata-rata yang lebih tinggi. Sehingga dapat disimpulkan bahwa penambahan label pada icon dan membesarkan ukuran tulisan dapat meningkatkan kepuasan pengguna aplikasi.
