Abstract

Development of educational games focuss on the problem occured on bay management, primarily on loading container at ship bay. The loading plan problem in ship bay commonly known as Master Bay Plan Problem (MBPP). The complexity of MBPP can be seen on its constraints, that are container weight, container destination, container size, container type, and the arrangement rule of container. The study case and playing rules in this game development are adjusted to contextual theory and real situation occured in container arrangement at ship bay. The prototype of this game is called StowaGame. StowaGame is a simulation-based educational games related to container arrangement in ship bay. This software are built with the integration of MBPP and entertainment concept. The effectivity of this educational game will be tested by several player. The MBPP concept of each player will be tested before and after playing the game. Paired-t test calculation shows that p-value is less than 0,05. Thus, it can be concluded that the educational game can educate people with container arrangement concept in ship bay.

Abstract

This article describes the development of an uncapacitated p-hub median problem model. The established model will be applied in determining the location of the hub. Generally in the median p-hub model problem, it is known that the number of hubs built with the total cost minimization function. In this developed model, there is no limit to the number of hubs and the function of the intended destination is how many hubs are built. The model also looks for where the hub location will be built and which nodes are allocated to each hub. By eliminating the limitation of the number of hubs built, the model adds a total total timeout limit. The numerical experiments are dealing with the model. The solution to solve the model using excel solver. So that it will be designed spread sheet excel appropriate model. In numerical experiments, dummy data representing real systems will be used with the aim of shortening computational time. Numerical experiments are performed in several conditions scenarios. Computational results generate the location of hubs and nodes allocated to each hub with various experimental scenarios.

Abstract

PT XYZ is company of logistics service of PT CI where this company hold responsible to logistics activity of PT CI that is covering distribution and warehousing. In transportation activity PT XYZ conducted armada outsourcing transport from some transporter every day. A problem faced in this time was truck rent expenses for the delivery of order to store. Hypothesis customer early from this research was if it done consolidation delivery of order customer, hence expected will be yielded to decrease cost rent daily truck which enough significant. At this research, consolidation conducted by developing method of saving heuristic. By using data of customer was same order on February, 10 2006, this research can reduce consumer of truck counted 3 truck and yield cost-saving rent equal to 18.87% from expense of early. This research also design software prototype for daily operational activities in determining used truck.

Abstract

Indonesia sebagai negara kepulauan sangat bergantung pada transportasi laut (kapal) dalam mendukung konektivitas dan distribusi logistik nasional. Dalam sistem penggerak kapal, propeller merupakan bagian inti karena berperan sebagai pedorong saat kapal beroperasi. Selain itu, propeller juga rentan mengalami kerusakan akibat kelelahan material, kavitasi, dan beban operasi jangka panjang. Kerusakan pada propeller dapat menurunkan performa kapal, meningkatkan konsumsi bahan bakar, dan berkontribusi terhadap peningkatan emisi gas rumah kaca. Tanpa strategi pemeliharaan yang tepat, praktik penggantian propeller secara berulang berpotensi meningkatkan beban emisi dan biaya karbon, sehingga dapat menghambat pencapaian target dekarbonisasi sektor maritim. Kemudian, penggunaan propeller baru menimbulkan dampak lingkungan yang signifikan akibat proses manufaktur yang bersifat intensif energi dan material. Seiring dengan penerapan carbon pricing dan meningkatnya tuntutan keberlanjutan, diperlukan strategi pemeliharaan propeller yang lebih efisien dan berkelanjutan. Penelitian ini menerapkan pendekatan Life Cycle Assessment (LCA) untuk menilai dan memembandingkan dampak lingkungan antara propeller baru dan strategi perbaikan (repair). Hasil analisis menunjukkan bahwa propeller baru menghasilkan dampak lingkungan sebesar 16.962 kg CO₂-eq, sedangkan strategi repair mampu memberikan penghematan emisi sebesar 10.000–12.000 kg CO₂-eq, bergantung pada tingkat kerusakan. Jika dikonversikan ke dalam skema carbon tax sebesar Rp30 per kg CO₂-eq, strategi repair menghasilkan environmental saving cost sebesar Rp305.400–Rp375.180 dibandingkan dengan propeller baru. Dengan demikian, penelitian ini menunjukkan bahwa repair propeller tidak hanya menurunkan emisi, tetapi juga memberikan manfaat ekonomi melalui penghematan biaya karbon, sehingga mendukung pengambilan keputusan yang lebih berkelanjutan di industri perkapalan dan galangan kapal terkait strategi pergantian propeller kapal.
