Abstract

Dalam kehidupan keseharian, manusia mengerjakan segala aktifitas yang padat, baik aktifitas berat maupun ringan. Sudah tentu akan memerlukan tenaga atau energi untuk melakukan semua kegiatan tersebut, Energi yang diperlukan manusia dapat diperoleh melalui konsumsi makanan dan minuman, termasuk makanan dan minuman yang mengandung alkohol. Etanol pada makanan dan minuman beralkohol telah dikonsumsi manusia sejak dahulu kala dengan berbagai tujuan penggunaan yang berbeda-beda. Konsumsi alkohol dalam jumlah besar akan menyebabkan seseorang teler atau mabuk. Dalam beberapa makanan dan minuman yang ada dipasaran banyak yang mengandung alkohol didalamnya walaupun dalam jumlah kecil. Jika minuman beralkohol dikonsumsi terus-menerus dalam jumlah berlebihan, maka dapat menyebabkan kegagalan pernapasan akut dan kematian. Karena etanol dapat menghilangkan kesadaran, manusia yang mengkonsumsinya dapat melakukan perbuatan buruk yang tidak disadar. Kecelakaan yang terjadi didalam berkendara merupakan bagian dari implikasi lain dari penyalagunaan penggunaan alkohol. Konsumsi alkohol yang terlalu banyak menurunkan kinerja manusia dalam mengemudi, sehingga meningkatkan resiko terjadi kecelakaan atau mengurangi peluang kelangsungan hidup pengendara. Sekitar 40% total kematian yang terjadi di lalu lintas berkaitan dengan penggunaan alkohol. Diperlukan sebuah sistem pendeteksi penggunaan alkohol terdapat pengendara, dengan tujuan mengurangi hal tersebut. Perancangan sistem ini menggunakan sensor MQ303A berbasis mikrokontroler ATMEGA328 dengan module GSM SIM800L. Perangkat ini menggunakan bahasa pemrograman C dan datalog yang tersimpan kedalam server menggunakan komunikasi internet.

Abstract

The project management approach plays an important role in controlling project activities carried out to minimize time and cost risks. Project management is usually used in construction projects such as general development to research and development activities. One crucial aspect in project management is scheduling the implementation time. Scheduling serves to determine the sequence, duration, and relationship between project activities. This research writing uses a quantitative research design by collecting primary and secondary data relevant to the research questions. This research also uses the Critical Path Method (CPM) approach, which is a method used to analyze project scheduling and project time planning as well as find critical paths to determine effective and optimal time in completing a project. This research was conducted on the Flower House Construction project at PT. XYZ. The results of this study indicate that the critical path obtained is as many as 6 activities or jobs, namely, (A) Measurement and installation of bowplanks, (B) Making and assembling iron poles, (D) Installation of iron poles, (E) Installation of stones for walls, (F) Plastering walls, (H) Painting and finishing. The critical path obtained from start to finish is 1 – 2 – 3 – 5 – 6 – 7 – 9.

Abstract

In the era of globalization and increasingly complex industrial competition, the digitalization of Supply Chain Management (SCM) has become a key strategy for enhancing efficiency, responsiveness, and competitive advantage. This study aims to examine the role of digital transformation in supply chain management through a literature review of 20 national and international journal articles published between 2017 and 2025. The analysis reveals that SCM digitalization—through the integration of technologies such as the Internet of Things (IoT), Big Data Analytics, Artificial Intelligence (AI), and blockchain—can significantly improve data visibility, accelerate real-time information flow, and support analytics-based decision-making. This transformation not only drives operational efficiency but also strengthens collaboration and supply chain resilience. However, the adoption of digital technologies still faces various challenges, including infrastructure limitations, high investment costs, and insufficient human resource readiness. Several studies also highlight that the impact of digitalization on product quality and sustainability is not yet optimal without improvements in quality management systems and supportive regulations. Therefore, sustainable and context-specific implementation strategies, as well as collaboration among government, industry, and academia, are essential. This study recommends further exploration of inclusive digital adoption models, cybersecurity reinforcement, and the integration of digital SCM aligned with sustainability and resilience principles to face global disruptions. With the right approach, SCM digitalization can serve as a strategic foundation for building adaptive, efficient, and competitive supply chains in the Industry 4.0 era.

Abstract

This research aims to increase productivity and identify potential risks of musculoskeletal injuries to workers at PT. Cemindo Gemilang. The RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) methods are used to analyze work posture and physical loads experienced by workers. The biomechanical approach is used as a framework for understanding the interactions between workers, tools, and the work environment. By measuring human physical work using the RULA and REBA methods, non-ergonomic work postures and the level of risk of musculoskeletal injuries associated with work activities in cement factories can be identified. The results of this research can provide recommendations for improving tool design, rearranging work spaces, and changing work procedures to reduce the risk of musculoskeletal injuries and increase worker productivity. By implementing the recommendations resulting from this research, it is hoped that PT. Cemindo Gemilang can achieve safer, more efficient and more productive working conditions.

Abstract

Penelitian ini bertujuan untuk mendapatkan nilai postur pekerja dan memberikan rekomendasi perbaikan sistem kerja dari proses persiapan, proses pengirisan dengan mesin, proses penggorengan dan pengemasan yang dilakukan operator pada UKM XYZ. Kegiatan tersebut masih menggunakan mesin tradisional dan peralatan sederhana sehingga operator melakukan aktivitas membungkuk yang cukup lama. Hal tersebut dapat menyebabkan keluhan musculoskeletal disorders (MSDs). UKM XYZ bergerak di bidang olahan makanan ringan berbahan dasar singkong atau ubi kayu. Penelitian dilakukan melalui beberapa tahapan, yaitu mendokumentasikan postur operator yang dilakukan saat bekerja, mengetahui skor, level risiko dan level tindakan dengan metode RULA, REBA, OWAS dan QEC serta memberikan rekomendasi solusi terhadap risiko ergonomi pada pekerja. Penelitian ini akan membandingkan metode-metode tersebut, dengan mengevaluasi input, proses (metodologi) dan outputnya. Hasil penilaian menunjukkan bahwa dari kelima elemen kerja, nilai paling beresiko terjadi MSDs pada pekerja terdapat di elemen kerja ketiga (menggoreng). Dari keempat metode menunjukkan hasil action level 3 pada elemen kerja ketiga. Dengan kata lain pemeriksaan harus segera dilakukan dan perubahan harus dilakukan secepatnya untuk menghindari gangguan pada sistem otot-rangka karena pembebanan yang terus-menerus.

Abstract

This study aims to analyze the posture value of manual material handling workers on operators at UKM XYZ. UKM XYZ is engaged in processed snacks made from cassava. One of the activities carried out by humans, especially in material handling (manual material handling) is carried out at workstations. These activities still use traditional machines and simple equipment so that the operator performs long bending activities. This can cause complaints of musculoskeletal disorders (MSDs). The work carried out by the operator is on the workers in the third work element (frying) and checking the heater. After conducting an interview with the operator at the work station, the operator felt a complaint of pain in the shoulder. If left unchecked, it will cause skeletal muscle injury. The purpose of this study was to determine and measure the operator's workload based on the calculation of RWL (Recommended Weight Limit). From the measurement results of the operators at the work station, it was found that this activity is a light activity based on the calculation of energy consumption and the actual lifting load is below the recommended load with a Lifting Index (LI) level <= 1, meaning that the weight of the lifted load does not exceed lifting limits and does not carry the risk of spinal cord injury.
