Abstract

The inventory replenishment process in the warehouse becomes difficult if there is uncertainty. It can cause warehouse performance not to be as expected. The warehouse is an important part of the supply chain subsystem, which smooths the flow of goods from upstream to downstream throughout the system. This paper uses system dynamics modeling to analyze the replenishment of raw materials where there is randomness in availability and reliability and their effects on the delivery lead time of the fleet. The model obtained is much simpler but more robust when compared to the analytical-mathematical model or the discrete-events simulation. Tests on the model show that the model can behave as it should logically. Several experiments were conducted to see how fleet availability's reliability can affect the delay in receiving or delivery lead time. One interesting thing revealed is that reliability does not have to be 100%, but there is a certain minimum threshold for the system to perform well. This is different from availability, which must be 100%.

Abstract

Pengendalian kualitas menjadi salah satu faktor penting untuk meminimasi kecacatan produk. Penelitian ini bertujuan untuk menganalisis cacat produk sablon souvenir keramik pada Ina Souvenir. Metode analisis menggunakan pendekatan seven tools yang dapat membantu menganalisis penyebab kecacatan produk. Hasil penelitian menunjukkan bahwa permasalahan utama terjadinya cacat produk pada pengerjaan sablon souvenir keramik adalah stiker sobek saat penempelan pada media keramik (41%), warna stiker buram (28%), serta pemasangan stiker yang miring (22%). Permasalahan ini terjadi dikarenakan tenaga kerja yang kurang teliti, penggunaan kertas stiker decal dan tinta printer yang kurang berkualitas, serta pelapisan clear cover coating pada kertas stiker decal yang kurang merata. Usulan perbaikan untuk meminimasi tingkat kecacatan pada sablon souvenir keramik yaitu pengawasan produksi secara lebih intensif, penggunaan kertas stiker dan tinta printer premium, serta proses pelapisan clear cover coating pada kertas decal yang diulang beberapa kali agar stiker tidak mudah sobek

Abstract

Recently, the productivity of porang tuber-based products has been growing well, especially after the Indonesian Government released a policy to prohibit the export of porang plants and their harvested products. One of the porang-based products is in the form of chips. Before processing, the porang tubers must be washed thoroughly to remove soil/dirt from the surface. The conventional washing process of each tuber can take up to 3-5 minutes. Therefore, the purpose of this activity is to design and manufacture porang washing equipment based on centrifuge washing model with rubber vibration. Four stages to carried out the program, i.e. designed and manufactured the washing machine, run the machine in laboratory, training activities to the porang farmers, and evaluation process. From the observation to porang farmers as our partner during the activity, it can be seen that the partners can operate the washing machine well. The results show that the washing process of porang tuber using this technology can save the washing time up to 90% compared to the conventional washing. The surface cleanliness of porang tubers resulted from the developed washing machine is the same as the conventional one. The noise level of the machine has met the requirement of Indonesian Government. It is clear that the usage of  the machine can increase the production capacity of products-based porang tuber. In addition, the use of this technology may promote a more comfortable and healthy work environment due to ergonomic reason, however, based on RULA analysis, the machine is still need to be improved in the future. Overall, the partners were satisfied with this activity and expected to have further programs in the future.

Abstract

Large-scale problems are complex and interrelated. Decisions made in these matters can have unexpected impacts. A systemic approach is a management method that can be used to solve systemic problems. This approach consists of two models, namely a qualitative model and a quantitative model. Qualitative models ensure that the issue is fully understood, while quantitative models allow for analysis of policy scenarios. In this article, the systemic approach methodology is briefly discussed. This methodology begins with a qualitative formulation in the form of a causal-loop diagram. Causal-loop diagram is a diagram that describes the cause-and-effect relationship between variables in a system. Next, this methodology is continued with quantitative formulation in the form of stock-and-flow diagrams. Stock-and-flow diagram is a diagram that depicts the flow and supply of resources in a system. Further computations for experimental purposes (up to policy scenario simulations) can be implemented using Vensim® software. This article discusses the systemic approach methodology up to the experimentation example stage.

This activity involved 5 institutional managers as the ABDIMAS partner. This activity aims to increase greenhouse operational efficiency while strengthening institutional capacity through the use of easy-to-operate digital technology. The implementation method uses a descriptive–implementative approach through the stages of observation and planning, implementation of technological solutions, and qualitative evaluation based on monitoring and discussions with partners. The results of the activity showed that the implementation of an Internet of Things (IoT)-based watering system was able to provide more centralized, efficient, and scheduled watering control, while the development of the institution's official website succeeded in expanding access to information, education, and publication of activities to the public. This activity not only implements digital technology and platforms, but also encourages increased technological literacy and partner independence in managing innovation sustainably.
