The Pak RT Bukit Lama Tofu Factory in Palembang City is a home industry that produces tofu daily. However, operational activities in this factory still do not implement effective working time standards and efficient facility layout. This has the potential to cause low productivity and increase the risk of workplace accidents. This study aims to identify the actual conditions of the production process and working hours, evaluate efficiency using Time Study, and propose layout improvements based on ergonomic principles. In addition, the 5S method approach is applied to create a clean, orderly, and safe work environment. The results of this study are expected to provide a real contribution to improving work efficiency, workforce safety, and become a reference for developing better work systems in the small and medium industry sector.</em></p> Tiara Wijaya, Muhammad Razif, Tuwandi Juniaro Copyright (c) 2026 Tiara Wijaya, Muhammad Razif, Tuwandi Juniaro https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1209 Wed, 04 Feb 2026 09:27:50 +0000 PERANCANGAN DAN IMPLEMENTASI WEBSITE PERUSAHAAN DI CV RIZQI INTI BUANA https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1301 <p><em>CV Rizqi Inti Buana still conducts promotion and information dissemination through conventional media such as WhatsApp and limited business networks, resulting in a narrow information reach and making it difficult for the company to compete with competitors who have already utilized digital platforms. The company profile is also still in the form of static files, making access to information for prospective clients less effective. This study aims to design and implement a company website as a medium for digital promotion and information delivery. The method used is the waterfall system development method with modeling using Unified Modeling Language (UML) and database-based design. The results of the study produced a system design consisting of four UML diagrams and thirteen database tables that were implemented into a company website. Testing was conducted in both a localhost environment and an online system at https://rib-batam.com/ using black-box testing, which showed that the system functions properly. The developed website helps the company expand its promotional reach and enables clients to directly access company profile and activity information more easily.</em></p> Nanda Jarti, Nofri Yudi Arifin, Deo Bagus Prayoga Copyright (c) 2026 Nanda Jarti, Nofri Yudi Arifin, Deo Bagus Prayoga https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1301 Wed, 04 Feb 2026 12:24:52 +0000 LITERASI AKUNTANSI SYARIAH PADA PELAKU UMKM: STUDI FENOMENOLOGIS https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1372 <p><em>Micro, Small, and Medium Enterprises (MSMEs) play an important role in the national economy, yet they still face limitations in financial management, particularly related to sharia accounting literacy. The lack of technical understanding and dominance of normative interpretations cause sharia accounting principles to not be applied systematically in MSME financial recording practices. This research aims to deeply understand the experiences and interpretations of MSME actors regarding sharia accounting literacy in business financial management. This research uses a qualitative approach with a phenomenological method through in-depth interviews with MSME actors. The research results show that sharia accounting is more understood as moral and ethical business values, such as honesty and avoiding usury, rather than as a formal financial recording system. The conclusion of this research affirms the existence of a gap between values and practices, thus requiring guidance and practical sharia accounting education tailored to MSME characteristics, as well as the development of contextual mentoring models so that sharia principles can be applied sustainably in daily business activities and decision-making.</em></p> Kholifatus Syaadah, Nishfu Nurbayanti, Syifa Fauzia, Dea Ananda Copyright (c) 2026 Kholifatus Syaadah, Nishfu Nurbayanti, Syifa Fauzia, Dea Ananda https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1372 Wed, 04 Feb 2026 00:00:00 +0000 URGENSI PEMISAHAN KEUANGAN PRIBADI DAN USAHA DALAM PENERAPAN AKUNTANSI SYARIAH PADA UMKM DI BATAM https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1382 <p><em>Micro, Small, and Medium Enterprises (MSMEs) contribute significantly to the national economy, including in Batam City. Despite their importance, many MSME actors experience difficulties in distinguishing personal finances from business finances, which negatively affects the reliability of financial statements and increases the risk of non-compliance with Sharia accounting principles. This study employs a descriptive qualitative approach using interviews, observations, and questionnaires involving MSMEs in the food and service sectors. The findings indicate that the mixing of funds is primarily driven by low financial literacy and the absence of practical and simple financial recording guidelines. As a result, financial reports tend to be inaccurate and Sharia compliance remains low. The study concludes that separating personal and business finances is a fundamental requirement for the proper implementation of Sharia accounting. Therefore, it recommends enhancing financial literacy, providing continuous assistance, and adopting appropriate bookkeeping models to support better financial management and governance.</em></p> Widya Ayu Kusumawati, Junia Athira Putri, Fathiyah Fajri Ramadhani Siregar Copyright (c) 2026 Widya Ayu Kusumawati, Junia Athira Putri, Fathiyah Fajri Ramadhani Siregar https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1382 Wed, 04 Feb 2026 14:05:11 +0000 PENERAPAN MODEL PROJECT BASED LEARNING UNTUK MENINGKATKAN HASIL BELAJAR SISWA PADA MATA PELAJARAN SISTEM KONTROL ELEKTROPNEUMATIK DI SMK NEGERI 1 BATAM https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1383 <p><em>This study aims to improve the learning outcomes of students in Grade XI Industrial Automation 3 at SMK Negeri 1 Batam through the implementation of the Project-Based Learning (PBL) model in the Electropneumatic Control Systems subject. This research employed classroom action research conducted in two cycles. The research subjects consisted of 41 students. Data were collected through learning outcome tests, observations, and documentation. The results showed that prior to the implementation of PBL, only 10 students (24.39%) achieved mastery learning with an average score of 59. In Cycle I, the number of students who achieved mastery increased to 23 students (56.10%) with an average score of 72. In Cycle II, the number of students achieving mastery further increased to 33 students (80.49%) with an average score of 79. These findings indicate a continuous improvement in students’ learning outcomes from the pre-cycle stage to Cycle II. Therefore, it can be concluded that the implementation of the Project-Based Learning model is effective in improving students’ learning outcomes in the Electropneumatic Control Systems.</em></p> Nelma Busra, Jaenuddin Jaenuddin Copyright (c) 2026 Nelma Busra, Jaenuddin Jaenuddin https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1383 Mon, 09 Feb 2026 00:00:00 +0000 ANALISIS SIMULASI MONTE CARLO DALAM MEMPREDIKSI PERMINTAAN JASA SERVICE KOMPUTER PADA HANIFNAFI COMPUTER BATAM https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1390 <p>Penelitian ini bertujuan untuk memprediksi permintaan produk dan mengoptimalkan persediaan pada Hanifnafi Computer Batam menggunakan Simulasi Monte Carlo melalui perangkat lunak Jamovi.

Hasil analisis menunjukkan bahwa permintaan paling mungkin berada pada rentang 35–45 unit, dengan risiko stok tidak laku sebesar 14% dan peluang lonjakan permintaan sebesar 11%. Penelitian ini menyimpulkan bahwa penggunaan simulasi Monte Carlo membantu pemilik usaha dalam menetapkan <em>safety stock</em> yang tepat guna meminimalkan kerugian akibat penumpukan barang atau kehabisan stok</p> Weni Lestari Putri, Nanda Jarti Copyright (c) 2026 Weni Lestari Putri, Nanda Jarti https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1390 Wed, 11 Feb 2026 01:12:38 +0000 ANALISIS DAN PENGENDALIAN RISIKO KESELAMATAN KERJA PADA SISTEM DISTRIBUSI PRODUK ELEKTRONIK MENGGUNAKAN METODE HIRADC https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1395 <p>Keselamatan dan kesehatan kerja (K3) merupakan aspek penting dalam sistem distribusi produk elektronik yang melibatkan aktivitas material handling dengan intensitas tinggi. Penelitian ini bertujuan untuk menganalisis dan mengendalikan risiko keselamatan kerja pada sistem distribusi produk elektronik di PT CBR Batam menggunakan metode <em>Hazard Identification, Risk Assessment, and Determining Control</em> (HIRADC). Metode penelitian yang digunakan adalah deskriptif–analitis dengan pendekatan studi kasus melalui observasi lapangan, wawancara, dan studi dokumentasi. Hasil penelitian mengidentifikasi 10 potensi bahaya utama pada aktivitas penerimaan barang, penyimpanan, pemindahan material, pengemasan, serta loading dan pengiriman. Penilaian risiko menunjukkan bahwa 40% aktivitas berada pada kategori risiko tinggi, dengan risiko tertinggi pada aktivitas pemindahan material akibat potensi tertabrak forklift yang mencapai nilai risiko 100%. Penerapan pengendalian risiko berdasarkan hierarki pengendalian mampu menurunkan tingkat risiko sebesar 50%–80%. Hasil ini menunjukkan bahwa metode HIRADC efektif dalam meningkatkan kinerja keselamatan kerja pada sistem distribusi produk elektronik.</p> Nurul 'Aini, Khoerun Nisa Safitri, Asrul Fole Copyright (c) 2026 Nurul 'Aini, Khoerun Nisa Safitri, Asrul Fole https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1395 Wed, 11 Feb 2026 00:00:00 +0000 ANALISIS PAPARAN GAS KARBON MONOKSIDA (CO) DAN PERILAKU PENGGUNAAN ALAT PELINDUNG DIRI (APD) TERHADAP KELUHAN PERNAFASAN PADA PEKERJA WELDING DI PT. X KOTA BATAM https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1393 <p><em>Respiratory complaints are a health problem that can be experienced by construction workers, especially welding workers, primarily due to exposure to Carbon Monoxide gas. This study aims to analyze the relationship between carbon monoxide (CO) gas exposure and respiratory Personal Protective Equipment (PPE) usage behavior with respiratory complaints among welding workers. This research is an analytical observational study with a cross-sectional design conducted at PT. X in Batam City, Riau Islands from February to July 2024. The entire population of 35 welding workers was taken as a sample through the total sampling method. Based on the research results, the chi-square statistical test shows a p-value of 0.030 &lt; α = 0.05 for the relationship between CO gas exposure and respiratory complaints, so Ho is rejected and Ha is accepted. This means that there is a significant relationship between exposure to carbon monoxide (CO) gas and respiratory complaints in workers. Furthermore, the chi-square statistical test for the relationship between PPE usage behavior and respiratory complaints resulted in a p-value of 0.046 &lt; α = 0.05, so Ho is rejected and Ha is accepted, which means there is a significant relationship. The results of this study show that 74% of workers were exposed to CO gas above the threshold limit value (25 ppm), 60% used respiratory PPE, and 63% experienced respiratory complaints. Suggestions for the company include evaluating working hours, periodic health monitoring, improving ventilation, optimizing PPE usage, and further research on lung function disorders using spirometry.</em></p> Jamal Jamal, Asnil Fauzi, Agung Sundaru Copyright (c) 2026 Jamal Jamal, Asnil Fauzi, Agung Sundaru https://creativecommons.org/licenses/by-nc-sa/4.0 https://ojs3.lppm-uis.org/index.php/JLIS/article/view/1393 Wed, 11 Feb 2026 13:54:45 +0000
