Abstract

PT. INKA merupakan perusahaan yang memproduksi kereta api, baik untuk dipasarkan ke dalam negeri maupun diekspor ke luar negeri. Pada periode tahun 2016, keterlambatan kedatangan material yang paling banyak pada proyek 5TSK3. Hal ini akan menghambat proses produksi kereta. Dalam studi kasus ini, akar penyebab keterlambatan dianalisi menggunakan cause-effect diagram dan metode kipling untuk menghasilkan usulan perbaikan guna mengurangi resiko terjadinya keterlambatan datangnya barang untuk proyek di masa depan. Dari hasil identifikasi masalah, diperoleh lima faktor yang menjadi penyebab keterlambatan kedatangan material proyek kereta 5TSK3, yaitu faktor material, manusia, metode, mesin dan lingkungan. Selain itu, dari faktor-faktor yang menyebabkan keterlambatan kedatangan material, diperoleh beberapa usulan perbaikan yang dianalisis menggunakan pendekatan tools teknik industri dan aliran aktivitas pengadaan material. Berdasarkan analisis, diperoleh Standard Operation Procedure (SOP) usulan untuk pengadaan material. Kata kunci: keterlambatan, pengadaan material, SOP

Abstract

Sustainable transport plays a key role in the fight against climate change, particularly in developing countries where reliance on conventional vehicles is high. Motorcycles account for the majority of the fleet of motor vehicles in Indonesia and contribute significantly to emissions. In order to achieve its Paris target of a 29 percent reduction of carbon emissions, the government is encouraging electric cars with various incentives. This study develops a willingness to consider (WTC) model for electric motorcycles in Indonesia based on the powertrain technology transition market agent model (PTTMAM) and utilizes Vensim software to simulate outcomes. The WTC model is built on the assumption that consumers' willingness to consider electric motorcycles is influenced by factors such as costs, marketing, and exposures. The system dynamics model consists of four modules: the conventional motorcycle, the electric motorcycle, the marketing module, and the willingness to consider module. The simulation results show an increasing trend in consumers’ willingness to consider electric motorcycles from 2017-2035, with the WTC value reaching 0.3209 in 2035. While this indicates a positive shift toward greater consumer interest in electric motorcycles, the growth remains modest and slow, reflecting the challenges of widespread adoption. Additionally, this study evaluates three government incentive and subsidy policy scenarios. The scenario results indicate that government subsidies and incentives can increase the consumers’ willingness to consider electric motorcycles in Indonesia, thereby increasing their market share. Among the scenarios, the purchase price subsidy is the most effective, as it directly reduces the financial barrier, encouraging more consumers to make the switch to electric motorcycles.

Abstract

The adoption of electric vehicles (EVs) is one of the solutions to reduce emission problems. Vehicle cost analysis is one of the keys to seizing the Indonesian market. As a consumer, it is not only the purchase price that needs to be considered, but the life cycle costs throughout ownership also need to be considered in the purchase. This study discusses the life cycle cost (LCC) of EVs in Indonesia, especially electric motorcycles (EMs), which will be compared with conventional motorcycles (CMs). In particular, this study aims to encourage the government's target for ownership of 2.1 million EMs in Indonesia by 2025. The novelty of this research is to develop a more comprehensive LCC model by considering the costs in terms of tangible and intangible to compare the two types of motorcycles using Monte Carlo simulation. This simulation is used to coordinate the behavioral uncertainty of motorcycle users. As a result, the value of an EM is more economical than CM for various users. The average value percentage of EMs is lower than CMs by 45% (IDR 30,6 million). In addition, several scenarios are also analyzed to maximize consumer welfare in Indonesia.

Abstract

Soybean self-sufficiency in Central Java Province is a problem that is difficult to realize at this time. As an important commodity, self-sufficiency becomes a serious concern for the government. Supply chain management of soybean is related to the integration of supply, demand, and distribution of soybean. The characteristics of entities involved in the soybean supply chain are complex, dynamic, and probabilistic that make the problem cannot be solved using an analytical model and it becomes too risky for trial and error. A suitable tool is using a simulation model. This paper deals with developing a Decision Support System (DSS) using a simulation model that will assist the government in adopting policies in order to achieve self-sufficiency of soybean and the improvement of farmer's welfare. DSS will help decision-makers to try various scenarios of policy in an easy way. The method was started with developing model components, then decision components, and next creating user interfaces. The simulation and system modeling is created by using Powersim software with the intent to obtain the simulation and single document interface (SDI) of the supply chain model. The result shows that land expansion policy is a top priority for realizing food self-sufficiency while increasing productivity and reducing costs of agricultural activities are the main priorities for improving the welfare of farmers.

Abstract

Electric buses are increasingly promoted as a sustainable public transportation solution in Indonesia's urban areas, yet their adoption rate from the user perspective remains relatively limited. This study aims to develop a user-oriented conceptual framework to explain the adoption process of electric bus services within Indonesia's urban public transportation system. The study employs a systematic literature review approach following PRISMA guidelines, analysing scientific articles published from 2015 to 2025, with a total of 30 studies examined in depth. Through content analysis, 13 main constructs were identified that integrate behavioral, psychological, technology acceptance, service attribute, and risk perception dimensions, based on the Technology Acceptance Model and the Theory of Planned Behaviour. Based on this synthesis, this study proposes a process-based conceptual framework that maps the stages of electric bus adoption, from evaluating service attributes to actual usage. To strengthen its empirical applicability, the constructs were operationalized into measurable questionnaire indicators adapted from prior studies and supported through expert review and pilot testing with electric bus users. This framework is positioned as an exploratory model to support the identification of factor structures and serve as a basis for empirical Research and the formulation of sustainable public transportation policies in Indonesia.
