Abstract

Penelitian ini berupa pengembangan Sistem Pendukung Keputusan (SPK) untuk perencanaan kebutuhan bahan baku yang mempunyai batas masa kadaluarsa dan adanya ketentuan diskon bagi  pembelian dalam jumlah tertentu. Sementara kebutuhan bahan baku setiap periode bersifat dinamis dan kapasitas gudang penyimpanan terbatas. Ketentuan diskon yang berlaku yaitu all unit quantity discount. SPK dikembangkan berdasar Model Budijati (2007) dengan pendekatan programa dinamis. Kriteria pemilihan solusi adalah minimasi total biaya persediaan. SPK ini dikembangkan dengan software Delphi. Hasil validasi program SPK menunjukkan bahwa SPK telah valid merepresentasikan kaidah proses perhitungan programa dinamis. Untuk pengujian kelayakan implementasi, SPK diujikan kepada beberapa pakar dan beberapa industri makanan. Dari hasil pengujian tersebut dapat disimpulkan bahwa SPK layak untuk diimplementasikan.

Abstract

Background: Kunir Jalak business unit is part of UPJ Surya Boga belonging to the Catering Department at SMK Muhammadiyah 1 Moyudan, Sleman. This unit produces a powder drink made from turmeric, ginger, and temulawak. This drink is intended to maintain immunity, considering the covid 19 pandemic. The Kunir Jalak business unit is relatively new, so it still needs assistance to develop its business. This community service activity aims to assist in determining business development strategies so that the Kunir Jalak business unit can be more developed. Contribution: The impact of community service activities is shown by increasing partners’ empowerment in identifying strengths, weaknesses, opportunities, and threats (SWOT) for the Kunir Jalak business unit and determining the alternative business development strategy, which has never been done before. Method: The method used is Focus Group Discussion (FGD) to determine strengths, weaknesses, opportunities, and threats (SWOT) and determine business development strategies. Furthermore, the Analytical Hierarchy Process (AHP) approach determines strategic priorities. Results: AHP analysis shows three business development strategies with the highest priority, namely: Weakness-Treats-1 (WT-1), Strength-Treats-1 (ST-1), and Weakness-Opportunity-2 (WO-2). Conclusion: Following the objectives of the community service program, it means that the priority of business development strategies can be determined, which can be used as guidelines for developing the business unit of Kunir Jalak.

Abstract

The handling of used cell phones in Indonesia is mostly carried out by informal actors, starting from second-hand market actors. However, the activities of the informal actors often endanger the environment and human health. To reduce the impact, some of the activities should be transferred to formal parties. This requires collaboration of both parties as a form of waste management, which previously has never been established. The objective of this study is to explore the driving factors of collaboration intention of informal actors in handling used cell phones with the formal ones. Data were collected using questionnaires distributed to second-hand market actors in five districts in the Special Region of Yogyakarta Province. In this study, three internal driving factors are considered, which are environmental attitude, management commitment, and financial benefits, as well as two external driving factors: government support and competitor pressure. The regression analysis in each region revealed that the most significant driving factors vary across different regions, such as government support in Gunungkidul, management commitment in Bantul, competitive pressure and government support in Kulonprogo, government support, management commitment, and financial benefit in Sleman, as well as environmental attitude and financial benefit in Yogyakarta City. From the structural equation modeling at the provincial level, it was found that financial benefit and government support were the most significant factors influencing the collaboration intentions of all informal actors. The results of this study can be used as a reference. Doi: 10.28991/CEJ-2022-08-10-016 Full Text: PDF

Abstract

Waste management is an activity to manage residues, by-products, and used items. Handling used cell phones is one form of waste management activity. In developing countries, used cell phones are mostly handled by informal actors, where second-hand market actors for cell phones act as collection points. Some of these activities often affect the environment and the actors' health due to a lack of adequate technology. Hence, a collaboration between informal and formal actors is necessary to handle the used cell phones and reduce the adverse effects. However, several obstacles faced by informal actors can hinder such collaboration. This study explores the inhibiting factors for the collaboration between the informal and formal actors in handling used cell phones. The respondents were 424 informal actors in five areas of the Special Region of Yogyakarta (DIY Province), Indonesia. The results showed that the unavailability of infrastructure and insufficient organization significantly hindered collaboration in the Yogyakarta municipal area. As for the areas of Gunungkidul, Bantul, Kulonprogo, and Sleman regions, there were no significant factors hindering the collaboration. The results of this study can contribute for stakeholders’ consideration related to e-waste handling, primarily used cell phones in Indonesia; thus, the management of used cell phones is safe for the environment and provide economic benefits for the informal actors. Doi: 10.28991/CEJ-2023-09-03-011 Full Text: PDF
