Abstract

Corona Virus Disease (COVID-19) pandemic dramatically impacted the energy sector. About 4.5% of global primary energy consumption dropped in 2020, where coal demand decreased by 220 million tons of coal equivalent. The drop was driven by lower electricity demand due to policies against Covid-19 (i.e., travel restriction, lockdown, and new standard). In particular, the COVID-19 crisis has already created profound uncertainties for the Indonesian coal mining industry as one of the world's largest coal producers and exporters. Coal is the primary energy source for Indonesian electricity, contributing to the national revenues. A debate about action to take, whether to focus on dealing with Covid-19 health or maintaining economic growth, is unavoidable. With the number of cases continuing to rise, we set out to investigate the impact of COVID-19 on Indonesia's coal mining industry. Rapid desk assessment and descriptive statistical approach were used in this study by evaluating secondary data during the pandemic, comparing with previous years before the COVID-19 pandemic. The results revealed a tangible transformation in coal demand, production, and price. Despite domestic coal consumption for power generation decreased, the coal price increased in mid of 2021 due to rising coal demand in China.

Abstract

Pandemi Covid-19 yang terjadi di Indonesia pada awal tahun 2020 meng­akibatkan pemberlakuan physical distancing berskala besar sehingga ber­dampak pada meningkatnya permintaan terhadap pengiriman makanan secara online. Dalam usaha meningkatkan pelayanannya dengan jumlah per­mintaan yang meningkat, UMKM rumahan pada penelitian ini merancang rute pengirim­an yang lebih efisien. Pada proses pengiriman sebelumnya hanya berdasarkan kapasitas armada pengiriman dan lokasi pelanggan yang terdekat dengan lokasi UMKM. Penelitian ini bertujuan untuk mengevaluasi rute awal pengirim­an dan menentukan rute baru dan urutan kunjungan ke setiap titik lokasi pe­lang­­gan dengan menggunakan metode saving matrix dan dengan meng­guna­kan algoritma nearest neighbor dan nearest insertion. Dengan mengguna­kan metode saving matrix didapatkan dua rute kunjungan. Ber­dasarkan perban­ding­an hasil pengurutan kunjungan pelanggan pada setiap rute, didapatkan jarak tempuh terpendek dengan menggunakan algoritma nearest neighbor. Total penghematan jarak tempuh yang didapatkan berdasar­kan penentuan rute dengan menggunakan metode saving matrix dan algoritma nearest neighbor adalah sebesar 34.5% (dari total jarak tempuh pada rute awal adalah 77.19 km menjadi 50.59 km pada rute yang baru).

Abstract

This study explores the influence of consumer attitudes, religious beliefs, and health consciousness on purchasing intentions and behaviours towards halal products within Indonesia’s Muslim community. Employing the Theory of Reasoned Action (TRA), this research structured hypotheses to assess how various perceptual and normative factors affect consumer decisions. The research method includes a quantitative survey with PLS-SEM to evaluate relationships between attitudes (consumer attitudes, health consciousness, and religious compliance), intentions, and purchasing behaviours, using a structured questionnaire distributed among 500 participants in Indonesia. Results indicate significant positive associations between consumer attitudes and purchasing intentions, purchase intentions and purchasing behaviours, as well as health consciousness and purchase intentions. Additionally, religious beliefs significantly influence purchase intentions. This research reaffirms the applicability of the TRA in predicting consumer behaviour in culturally sensitive markets. Businesses should ensure all halal products are clearly labelled with a certified halal logo to reassure consumers about the authenticity of the product's halal status and address concerns about ingredients and processing.

Abstract

Developing a Multi-Maximal Covering Location Model (MMCLM) for waste management in Gondokusuman Sub-district, Yogyakarta, Indonesia, is urgently needed. The closure of the Piyungan landfill has resulted in the need for additional Reduce, Reuse, and Recycle Waste Management Sites (3R-WMSs) to reduce waste that the landfill cannot accommodate. The primary objective of this model is to optimize the location and allocation of demand volume nodes, representing the resident population, to a specific set of 3R-WMS. These demand nodes are located at different distances from 3R-WMSs, including high and low coverage areas. The research in the Gondokusuman Sub-district employed MMCLM with facility capacity constraints and was developed using mixed integer linear programming methodology. The study identified five optimal locations for a 3R-WMS establishment that comprehensively cover all demand nodes (15301) and population clusters (45903) in the sub-district, including both high (5085) and low coverage areas (10216). This research represents a significant step forward in developing a sustainable environment by ensuring easy access to reducing, reusing, and recycling-based waste management facilities for residents.

Abstract

Halal risk mitigation in certified poultry processing is the focus of this study.  The primary objectives are to map the important risk points in the halal poultry supply chain, understand how certification criteria are applied, and evaluate how stakeholder awareness and behaviour affect halal compliance. This research applied a descriptive qualitative approach, leveraging the case study technique through interviews with major stakeholders in the chicken meat supply chain. This research uses source triangulation techniques to validate the data by comparing information from interviews and literature reviews. The findings reveal several critical issues in the halal poultry supply chain, including limited control over halal inputs such as feed and vaccines, and low awareness among farmers regarding halal standards. Inadequate transaction documentation and the unclear halal status of chickens during transfer further compromise compliance. The slaughtering process often does not adhere to shariah requirements, with poor separation between clean and dirty areas, increasing the risk of cross-contamination. Additional concerns include contamination during transportation due to the use of non-designated or unhygienic vehicles, and the absence of halal labelling alongside the use of ingredients from unverified sources.

Abstract

Humanitarian aid relief has been operational since the late 19th century, addressing development and disaster aid cases. The intricate relationship between humanitarian aid relief and the supply chain encompasses various stages, from securing funding to coordinating stakeholders. However, the volatile and uncertain nature of the field poses challenges such as corruption, prolonged funding gaps, and demands for accountability and visibility. This study highlights the critical role of funding and financing in the humanitarian supply chain, emphasizing the underdeveloped state of research on supply chain finance (SCF). The paper aims to investigate the integration of SCF into humanitarian aid relief, utilizing literature reviews from journals, papers, and reports.The findings reveal a correlation between SCF's essential elements—focused on liquidity/cash, operational activities, and engagement among actors. This research proposes a framework, how the humanitarian aid relief sequence and SCF theory should collaborate for effective humanitarian aid supply chain finance (HASCF) practices
