<![CDATA[Corona virus has a destructive impact on the world's economy, especially in Indonesia, making a large-scale social restriction policy (SRL). Many restaurants, hotels, schools, and colleges in Yogyakarta are closed. Consumers, mostly students from outside Yogyakarta, have to return to their hometowns. This case impacts the decline in chicken prices to cover losses due to excess supply and decreasing demand. This research aims to analyze the decline in chicken prices, halal products' and the concept of marketing strategies impact on the chicken supply chain during the Covid-19 outbreak in Yogyakarta. This research used SEM to obtain accurate analysis and descriptive results to overview phenomena from society under study. The analysis using SEM shows that halal factors do not significantly affect consumer decisions in buying chicken. However, it was found that there was an increase in consumers in online shopping, which could create new strategies in marketing strategies. The application of online marketing strategies will improve consumers' services so that it is expected to be a novel value that can increase consumer buying interest during the Covid-19 outbreak in Yogyakarta, Indonesia.]]>

<![CDATA[The automatic testing machine, called by mixed-load tester, has ability to load and test multiple product families in different testing durations simultaneously. However, the high product mixes for each product family undergoes a different process flow. In addition, the capability of the robot inside tester used for loading and unloading a product to each slot makes the capacity planning problem more complicated. It effects low tester utilization. This paper developed simulation models of capacity planning scenarios under demand and testing time uncertainty. These scenarios are built by robust optimization to handle worst case condition. The result shows the proposed solutions gives better tester utilization and improves the decision making process by providing more detailed and precise information about capacity planning under uncertainties that was not available in company`s current method. To the best of our knowledge, this developed model is the first one considering the mixed–load tester under uncertainties.]]>

<![CDATA[The ABC metal SME produces some wastes, such as liquid waste, solid waste, and smoke. The problem is hazardous waste dumped directly into the environment without any waste treatments which had bad impact on the environment around its SME. Therefore, this research is proposed to improve the production process of metal that can reduce the environmental impacts. The Life Cycle Assessment (LCA) method is developed to identify all the processes that have an impact on the environment and also to calculate the energy used. The values of environmental impact are calculated using Simapro 9.0 Software. In addition, Analytical Hierarchy Process (AHP) method is employed to determine the best alternative fuel according to four criteria, such as temperature, price, emission, and fuel consumption. The results show the process that has the greatest environmental impact is the metal smelting process. It is caused by the source fuel in this process was used oil. The usage of used oil can be the sources of air pollution that causing health problems in the respiratory tract such as bronchitis and asthma. Some alternative fuel was proposed, however, fuel gas is the best alternative among others according to the expert opinions. For the managerial insight, this research can be suggestion for SME to choose the best fuel in the production process that considering economic and environmental aspects.]]>

<![CDATA[Proses daur ulang yang tepat pada jenis sampah plastik dapat membawa keuntungan dari sisi ekonomi. Plastik sendiri merupakan salah satu jenis sampah yang memerlukan waktu yang lama untuk terurai. Hal ini yang disadari oleh pengurus bank sampah tidak terkecuali di wilayah Kota Yogyakarta, salah satunya bank sampah yang berada di Lowanu. Bank sampah ini melakukan daur ulang sampah plastik botol air mineral dan plastik sachet menjadi kreasi meja ecobrick. Selama ini kreasi meja ecobrick yang dihasilkan hanya sebatas dipajang pada pameran hasil pengolahan sampah yang diselenggarakan oleh Badan Lingkungan Hidup (BLH) setempat. Pengurus bank sampah belum memiliki keberanian untuk menjual meja kreasi ecobrick kepada calon konsumen. Hal ini disebabkan pengurus tidak dapat menentukan harga jual yang tepat sehingga calon konsumen tertarik untuk membeli. Maka dari itu penelitian ini dilakukan untuk dapat mengetahui harga pokok produksi yang dihabiskan untuk menghasilkan meja kreasi ecobrick, sehingga pengurus dapat menentukan harga jual berdasar besarnya margin yang mereka tetapkan. Metode full costing digunakan untuk memecahkan masalah ini. Harga pokok produksi untuk setiap unit meja kreasi ecobrick adalah sebesar Rp 107.600.]]>

<![CDATA[Yogyakarta has increasing trends in the number of vehicles and consequently intensifying the traffic volume and will effect to higher emission and air pollution. Traffic lights duration plays a vital role in congestion mitigation in the critical intersections of urban areas. This study has objective to minimize the number of vehicles waiting in line by developing the hybrid simulation method. First of all, the MKJI and Webster method were calculated to determine the green traffic light. Then, the simulation model was developed to evaluate the number of vehicles waiting in line according to different duration of green traffic lights from MKJI and Webster method. A case study will then be provided in Pelemgurih intersection located in Yogyakarta, Indonesia for demonstrating the applicability of the developed method. The result shows that the duration of green traffic lights calculated by Webster method provides lower number of vehicles waiting in line. It is due to the short duration of green traffic light resulted by Webster method so that the traffic light cycle becomes shorter and it effects the number of vehicles waiting in line which is lower than MKJI method. The results obtained can help the generating desired decision alternatives that will important for Department of Transportation, Indonesia to enhance the road traffic management with low number of vehicles waiting in line.]]>

<![CDATA[Waste is a problem in environment and society that has never been resolved. One of the triggers for waste is the use of disposable product packaging. Reducing single-use waste by reusing it will impact reducing waste generation so that the city becomes clean. Reuse of waste by making it the basic material for an innovative product will add value to waste to no longer pollute the environment. The existence of the Kampung Sayur program in Brontokusuman has made waste no longer underestimated. The location of Brontokusuman in the middle of a densely populated city is an obstacle in implementing “the vegetable village” program so that the need for community empowerment in managing waste wisely. The community empowerment program implemented in Brontokusuman aims to provide education to the community in managing waste. organic and non-organic wisely.Therefore, the training of vertical garden was conducted to support that program]]>
