Abstract

Latar Belakang: The Body Shop merupakan perusahaan kosmetik yang telah mengkampanyekan program daur ulang. Kampanye ini menarik konsumen untuk mendapatkan poin yang selanjutnya dapat ditukar dengan pembelian produk baru. Kehadiran kampanye ini menarik emosi positif masyarakat dalam pembelian barang dengan dalih cinta lingkungan. Penelitian ini bertujuan untuk memahami peran kampanye yang dilakukan oleh perusahaan The Body Shop. Metode: Desain penelitian yang digunakan bersifat konklusif; menguji hipotesis yang dihasilkan oleh penulis untuk mengenali kausalitas antar variabel dalam model yang sudah ditentukan, memberikan gambaran hubungan yang ada antara variabel-variabel independen (attitude, perceived behavioral control, subjective norms, moral norms, willingness to sacrifice, anticipated positive emotions), dan variabel independen (return intention) yang disertakan dalam penelitian. Penulis melakukan pengumpulan data secara cross-sectional. Temuan: Berdasarkan hasil penelitian ditemukan bahwa enam variabel yang diusulkan dalam model studi kasus terhadap penerapan reverse logistics The Body Shop tidak sepenuhnya sesuai dengan hipotesis-hipotesis yang dibangun. Dalam perbandingan antara penelitian yang dilakukan oleh penulis dengan jurnal utama, setiap penelitian memiliki data primer serta justifikasi yang menjadi kerangka dari argumen yang dihasilkan. Kesimpulan: Berdasarkan hasil penelitian walaupun para responden merasa mereka memiliki waktu luang dan persepsi pengendalian perilaku yang cukup untuk berpartisipasi dalam program BBOB, keterbatasan-keterbatasan lain dapat memainkan peran sebagai penyebab tidak signifikannya hubungan antara niat pengembalian dengan perceived behavioral control.

Abstract

Managing multiple third-party logistics providers (3PLs) for export shipments presents a complex challenge for large manufacturers like PT. X, involving both explicit and implicit costs that impact overall efficiency and cost-effectiveness. This study aims to develop an optimal 3PL order allocation model for PT. X's export operations by integrating Total Cost of Ownership (TCO) to capture comprehensive costs and Integer Programming (IP) to minimize these total costs. A case study approach was employed, utilizing data from PT. X, including 3PL quotations, operational records, and quality performance metrics. The TCO framework incorporated both explicit costs (e.g., shipment and service fees) and implicit costs (e.g., management and quality failures). An IP model was then formulated to allocate orders across five 3PLs while adhering to operational constraints on minimum and maximum volumes per 3PL and shipping liner. The combined TCO-IP model achieved a cost saving of Rp 1.52 billion (4.57%) compared to PT. X's previous allocation method. Sensitivity analysis revealed that implicit costs (communication and quality), while captured by TCO, had an insignificant impact on the overall allocation due to their small proportion in the total cost structure. The research demonstrates the practical value of combining TCO and IP for strategic logistics decision-making, enabling significant cost savings. It suggests that for PT. X, minimizing explicit costs is the primary driver of optimal 3PL allocation, though monitoring implicit costs remains important.

Abstract

Background: This study aims to analyze the performance of the production system currently implemented by Tahu Bandung ALN and propose alternative improvements that can make the performance of the production system more efficient. Methods: This study uses a discrete-event simulation approach, and the parameters of performance used are total production time and total production costs. Finding: The results of the base case scenario simulation found that there are several production processes that have waiting times which indicate the bottlenecks. Therefore, two alternative of improvements are proposed, namely the first scenario (adding more resources in the production processes that have waiting times) and the second scenario (combination of adding more resources in the production processes that have waiting times and implementing the inventory policy of certain raw material). Conclusion: The first alternative scenario is the better one as it can provide an improved performance, in which the total production time is reduced by 22,40% and the total production cost is reduced by 40,57%.

Abstract

Pharmaceutical distribution companies operate under tight profit margins and face increasing expectations to adopt environmentally sustainable practices. In Indonesia, companies like PT XYZ manage complex, multi-node distribution networks that supply pharmaceutical products nationwide. This complexity presents challenges in optimizing allocation decisions that address both operational efficiency and environmental sustainability. This study aims to develop a multi-objective optimization model that minimizes both total distribution costs and carbon emissions. The model is constructed using operational data from PT XYZ’s enterprise resource planning (ERP) system for 2024. The optimization employs a weighted sum approach with minimum deviation to achieve an optimal trade-off between distribution cost and carbon emissions. This approach is evaluated under constraints related to warehouse capacity, transporter load limits, delivery timeliness, and product integrity. The results indicate that model produce efficient distribution patterns, the minimum deviation method provides a more balanced trade-off between cost and environmental impact. This outcome is especially relevant for companies seeking to align logistics performance with sustainability objectives. By integrating financial and environmental goals into a unified decision-making framework, this study provides a practical solution for pharmaceutical logistics planning. It offers strategic insights into optimizing delivery networks, selecting transport modes, and evaluating the environmental implications of distribution decisions.

Abstract

The pharmaceutical industry in Indonesia has grown significantly, accounting for 27.8% of the ASEAN market share. However, despite this growth, the sector faces challenges, including intense competition, complex supply chain dynamics, and inefficiencies in production processes. This research investigates the factors contributing to the production decline and identifies non-value-added activities in the Vitamin C production line using Value Stream Mapping. The study applies Lean Manufacturing principles, supported by Root Cause Analysis, to propose improvement strategies that enhance line utilization and reduce waste. Data were collected through observation and interviews leading to the development of current and future state process models. The findings reveal that ineffective scheduling, prolonged changeover times, and labour-intensive documentation significantly reduce production efficiency. To address these issues, the study recommends the implementation of rapid testing technologies, electronic batch records, and a Laboratory Information Management System. These interventions are expected to result a 62.7% reduction in lead time and a 176% increase in production capacity. Financial analysis indicates strong economic feasibility, with a positive net present value and short payback period. This study concludes that Lean Manufacturing tools, when tailored to pharmaceutical operations, can drive substantial improvements in productivity, process flow, and operational resilience.

Abstract

Business process improvement is a well-known technique for organizations to identify processes that enhance business performance. This study aims to analyze and improve business processes in the company's principal operational processes that are directly related to controlling service requests for assistance with traffic problems on the toll road (Command Center), specifically in communication and handling requests for assistance and complaints from users of one of the toll road operators in Indonesia. Research is conducted by identifying existing processes, the underlying causes of existing problems, and analyzing business processes using the Business Process Improvement methodology and the Bizagi Modeler with Process Modeling and Notation (BPMN). An improvement within this approach is thus examined in a particular scenario. The as-is and to-be processes are measured using a technique of improvement design called the ESIA approach, consisting of four steps: eliminate, simplify, integrate, and automate. The result of the integration of Command Center services can decrease the response time for assisting requests from toll road users and enhance cost-effectiveness, improving customer satisfaction and the overall quality of toll road service.

Abstract

The purpose of this study is to analyze the influence of the dynamic business environment, the type of the company’s business strategy external labor flexibility, and internal labor flexibility on the firm performance. The unit of analysis in this study is the company, i.e. the companies in the telecommunications sector in Indonesia. This study uses primary data, through the distribution of questionnaires. Statistical technique used is partial least squares structural equation method (PLS-SEM). The findings suggest that the implementation of labor flexibility is important for the company to compete more efficiently in the market, but the implementation should match the company’s goal. Moreover, to achive the best firm performance, the company may implement both types of labor flexibility, however the implementation of internal labor flexibility should have higher priority.

Abstract

The Indonesian Electricity Company (PLN) is one of the main players in the energy transition in Indonesia, and the company plans to achieve net zero emissions by 2060. One way to do this is by implementing the de-dieselisation program, i.e. reducing the use of diesel power plants (PLTD) with new energy and renewable power plants. The Indonesian electricity supply business plan (RUPTL) 2021-2030 targets the reduction of electricity supply from PLTD by 87% by 2030. The program requires a method to determine the order of priorities of PLTDs to be de-dieselised. This research uses multicriteria decision making, namely, analytical hierarchy process (AHP) and technique for order preference by similarity to ideal solutions (TOPSIS) to develop a prioritisation methods and determine the rank of priorities of 22 PLTDs Sumatra island that will undergo de-dieselisation. The criteria are identified from the literature and confirmed with four experts from the company. The criteria are categorised into security of supply, costs, and environmental factors. AHP is then used to calculate the weight of all criteria and sub-criteria, while TOPSIS is used to determine the rank. The results show that the affordability criterion is the most critical factor (0.535), followed by the security of supply (0.312) and environmental factors (0.153). The results also show that PLTD A18, A14 and A7 are the top three PLTDs prioritised for de-dieselisation because they provide the closest distance to the ideal criteria. This research contributes by providing reference in selecting the PLTD that will be selected for de-dieselisation program.

Abstract

Provinces in the eastern part of Indonesia still have high percentage of residents living below the poverty line. However, some provinces are the producers of food commodities. The One Village One Product (OVOP) movement has been proven to be able to reduce the poverty level and can be implemented in East Indonesia, especially by developing the community-based food industry. The objective of the research is to develop a decision making model to determine the best suitable community-based food industry to be developed optimally in East Indonesia using Analytic Hierarchy Process (AHP). We identify five criteria for the model from the literature and interviews with experts, namely resources, demand, supporting industries, strategy and competitiveness, and supports from government and other parties. We apply the model for the case of East Sumba regency of the East Nusa Tenggara (NTT) province, to select from alternatives, namely cassava, banana, corn and peanut-based food industries. The results show that banana-based industry is chosen as the best-suitable community-based food industry, mainly due to the uniqueness of the banana-based product and high production of banana in the area.
