Abstract

Construction and material shops involve various high-risk activities, making Occupational Safety and Health (OSH) practices essential. This study aims to build a clear picture of existing safety practices and key risks in building material retail requiring attention through structured safety initiatives. Based on the findings, this study provides recommendations to improve OSH practices for workers in these environments. HIRA (Hazard Identification and Risk Assessment) and JSA (Job Safety Analysis) methods were employed to identify potential occupational hazards by defining the characteristics of possible hazards and evaluating associated risks. The findings reveal several unsafe acts and conditions from various working process and activity leading to potential hazards. A total of eight potential hazards were identified with HIRA uncovering one extreme risk, three very high risks, three high risks, and one medium risk. Among these potential hazards, manual handling posing the highest risk, followed by ergonomic issues, dust exposure, and contact with sharp objects where all classified as very high risks. To mitigate these risks, by using JSA, a combination of engineering controls, administrative measures, and PPE use was recommended in order to improve material handling, workstation conditions, and safety equipment usage. These recommendations serve as the foundation for implementing a proper OSH management system.

Abstract

Perumahan adalah salah satu kebutuhan dasar bagi kehidupan manusia. Seiring dengan tingkat pertumbuhan penduduk, terjadi peningkatan kebutuhan rumah. Tingginya permintaan ini membuat peluang bagi perusahaan properti, salah satunya PT X yang berada di Lampung. Untuk dapat terus maju dan berkembang, sebuah perusahaan harus berinovasi supaya dapat bersaing dengan perusahaan lain. Penerapan teknologi informasi berupa Business Intelligence (BI) dapat meningkatkan keunggulan bersaing. BI merupakan sebuah proses untuk melakukan ekstraksi data-data yang dapat meningkatkan keunggulan sebuah perusahaan. BI dapat menjadi alat bantu mengolah data-data menjadi informasi yang bernilai lebih dan membantu perusahaan untuk membuat keputusan manajemen yang lebih baik berdasarkan data yang dimiliki. Implementasi BI yang dilakukan berupa pengolahan data penjualan perumahan PT X dan juga data-data lain yang diperlukan sehingga dihasilkan output berupa tampilan visualisasi dan informasi melalui dashboard informasi yang dapat memberikan wawasan mengenai kondisi pasar perumahan yang ada di Lampung. Langkah-langkah yang dilakukan dalam implementasi BI ini dimulai dari pengumpulan data, pengolahan data melalui metode Extract, Transform, Loading (ETL) yang kemudian dilanjutkan dalam metode Online Analytical Processing (OLAP) untuk melakukan analisis. Akhirnya dihasilkan visualisasi data yang dapat menggambarkan relasi dan pola antara variabel yang ada dalam data dan mengkomunikasikan informasi secara jelas dan efektif melalui sarana grafis.

Abstract

Penelitian ini berfokus pada peningkatan kinerja penjualan PT. X, sebuah perusahaan ritel di industri fashion dengan lebih dari 25 cabang dan 500 produk. Penelitian ini mengusulkan desain dasbor berbasis self-service business intelligence (SSBI) menggunakan perangkat lunak Tableau untuk mengatasi masalah seperti kelebihan stok, kekurangan produk, dan kurangnya alat analitik untuk pengambilan keputusan. Penelitian ini mengintegrasikan peramalan permintaan dan analisis keranjang pasar untuk meningkatkan manajemen persediaan serta mengembangkan sistem paket penjualan produk yang lebih menarik. Lima dasbor dirancang, mencakup kinerja penjualan, peramalan permintaan, dan analisis pasar. Dasbor ini bertujuan memberikan wawasan yang dapat ditindaklanjuti bagi pengambil keputusan, meminimalkan kerugian, dan mengoptimalkan strategi pemasaran. Hasil penelitian berupa prototipe yang mampu mengubah data mentah menjadi format visual yang menarik dan mudah digunakan, sekaligus mengurangi ketergantungan pada spesialis teknologi informasi serta mendorong pengambilan keputusan berbasis data.

Abstract

The case study focuses on a multi-product company in Indonesia that aims to develop a proactive manufacturing strategy to tackle production disruptions caused by process uncertainty. Data from 30 periods are analyzed to evaluate the company's weekly production plan performance, revealing consistent quantity fulfillment but significant discrepancies in the types of products produced compared to the plan. Process uncertainty, especially regarding quality, leads to disruptions such as uneven and inadequate material supplies. Statistical Process Control (SPC) tools, like Pareto analysis, are used to identify priority quality issues, forming the basis for Fault Tree Analysis (FTA) to trace root causes and determine intervention points. Each machine's limited set of valves and pipes poses challenges for thorough cleaning during downtime and quality management outside working hours. Introducing backup valves and pipes per machine can mitigate these issues and improve production efficiency. Companies can implement procurement strategies for pipes and valves to prevent dirty prints in the primary process, ensuring smooth material supply and minimizing disruptions. Although actual production plan achievement hasn't reached 100%, this strategy has the potential to increase product sales by 3.31% by reducing the rejection ratio of dirty prints. Ultimately, proactive procurement of spare pipes and valves is expected to increase production efficiency by 4%, indicating enhanced production schedule stability.

Abstract

The COVID-19 pandemic has caused significant changes in almost all sectors, including disruptions in the global supply chain. Acceleration of supply chain recovery to create supply chain resilience and sustainability by implementing various strategies, including digitalization. Empirical evidence is still very limited in the literature, especially in studies involving supply chain actors from MSMES with different characteristics and locations. Therefore, this study aims to address this problem by analysis the role of digitalization in improving supply chain resilience and sustainability based on a case study of MSMES in Balikpapan City. Three hypotheses have been proposed to answer the research problem. This study uses the Structural Equation Modelling (SEM) approach with the help of IBM AMOS software version 22 for hypothesis testing. Questionnaires were distributed to 200 MSME actors with different characteristics in Balikpapan City. The results are: (1) the role of digitalization has a significant positive effect on supply chain resilience; (2) the role of digitalization has a positive effect on supply chain resilience; (3) supply chain resilience has a significant positive effect on supply chain sustainability. Despite the differences in characteristics of business models and business sectors, supply chain resilience and sustainability can be improved by using appropriate digital technology in each supply chain. The contributes of this study shows that there is a potential for good supply chain visibility that allows every actor along the supply chain to monitor, transfer, and improve the accuracy of decision making accurately and quickly, to handle any disruptions and improve supply chain sustainability.

Abstract

A strategy to save cost related to oil exploration process is discussed in this paper. The focus is to reduce the cost in slickline and electric line operation in order to maintain the business continuity, where this conclusion was obtained by looking at the comparison between the costs incurred during previous operations with the costs incurred at this time by comparing the results of operations obtained as well as comparisons with oil and gas prices both before and after 2018. This concrete step to be taken is a method for lean management because there is a cost suppression in it. The context of its implementation is through Business Process Re-engineering which of course will implement appropriate method steps to be taken. The method steps taken are to implement Value Stream Mapping which in its preparation includes an analysis of the slickline and electric line operation work steps carried out, including by compiling; Product family or operation work steps, Current state map of both operations and Design future state map of Wire Line operation proposal and 5S theory process as completeness. The proposed strategy enable to reduce costs by combining slickline and electric line operations in one unit or one service company, then reducing the number of workers involved and making work more efficient, by reducing the Rig up and Rig process, Down PCE (Pressure Control Equipment), reducing the repetition of the work intervention process.
