Abstract

There are numerous external costs associated with logistics that can potentially have an indirect influence on businesses or society as a whole. The purpose of this research paper is to provide an overview of the external costs related to the health of truck drivers and how it can potentially have a detrimental effect on supply chains. Truck drivers are vital contributors to the logistics and transportation sector and their role has a significant impact on the global economy. However, the demanding nature of their profession often leads them to neglect their own well-being and health, which in turn can have negative consequences for the drivers themselves, their companies, and the overall supply chains. This is a crucial issue that has unfortunately been largely overlooked in the existing literature on logistics and transportation. The objective of this paper is to identify the matter and propose a solution which involves monitoring the stress and fatigue levels of truck drivers in real-time using wearable device sensors and the Internet of Things. The aim is to create awareness within the logistics community and to encourage future research that can help mitigate the issues that may arise due to the presence of unhealthy truck drivers.

Abstract

Air merupakan tiga perempat bagian yang paling banyak dalam tubuh manusia. Manusia rata-rata membutuhkan asupan air sebanyak dua liter dalam satu hari. Kekurangan 1-2% air pada tubuh dapat mengakibatkan fungsi otak menjadi terganggu. Air yang berkualitas dijelaskan dalam tiga parameter, yaitu parameter fisika, kimia dan biologi. Pentingnya pengukuran tingkat pH dan karbon dioksida pada air merupakan upaya agar dapat mengetahui apakah kualitas air yang diukur memiliki tingkat keasaman yang baik atau buruk. Tujuan dilakukan pengujian ini adalah untuk mengidentifikasi karbon dioksida dan pH yang terkandung di dalam air. Hasil dari pengujian akan dijabarkan menggunakan metode deskriptif kuantitatif, yaitu penyajian data yang diperoleh dari perhitungan jumlah senyawa beserta pengamatan terhadap angka yang muncul pada alat pengukur secara jelas dan sistematis. Pengujian yang telah dilakukan menghasilkan nilai pengukuran kadar karbon dioksida tertinggi dan terendah masing-masing dari sampel A5 (12,32 mg/L) dan A1&A3 (3,52 mg/L). Nilai pH tertinggi dan terendah masing-masing diperoleh dari sampel A4 (8,4) dan A1 (7,9). Hasil pengujian ini membuktikan bahwa perbedaan jenis air akan memengaruhi nilai pengukuran disertai faktor intensitas cahaya yang masuk dan jenis pereaksi yang digunakan dalam proses pengukuran.

Abstract

This study aims to analyze the sulfur, saponin, and cardiac glycoside content in cassava tapai using three different processing methods: steamed tapai, plastic-wrapped tapai, and boiled tapai. Chemical tests were conducted to identify the presence of these three components in two separate trials for each sample. The test results revealed that none of the three types of tapai contained sulfur. However, plastic-wrapped tapai showed a significant presence of saponin, with the test results indicating a considerable amount (++), in the first trial and a moderate amount (+) in the second trial. Meanwhile, no saponin was found in either steamed or boiled tapai. Additionally, cardiac glycosides were detected in all three types of tapai, in both the first test and the repeated test, with results consistently showing (+) for all samples. This study provides insight into the differences in chemical composition based on the processing method used, which can influence the nutritional value and functional properties of cassava tapai.

Abstract

Competition among manufacturing companies drives industrial growth to adopt a competitive pattern. One way for companies to compete and avoid falling behind is by optimizing production activities through scheduling each workstation (job shop scheduling). This scientific article employs a literature review method with an evidence-based approach to identify relevant case studies. The research findings indicate that the job shop scheduling model has a significant positive impact on companies, such as increasing production efficiency and enhancing resource performance, ultimately minimizing costs and production time. However, it cannot be overlooked that this model also has negative effects, such as increased waste, pollution, and depletion of non-renewable resources. Therefore, the manufacturing industry must implement the concept of sustainability, focusing on three main pillars: economic, environmental, and social aspects. This approach aims to maintain productivity, enhance the quality of production performance, and minimize risks associated with optimizing job shop scheduling, ensuring maximum profitability for the company.
