Abstract

Indonesia has a significant potential for silica sand. Yet, the utilization of solar energy is less than that of fossil fuels, while the conversion of renewable energy is becoming increasingly prevalent. On a residential scale, as the largest consumer of electricity, the use of solar modules has not yet reached the scale targeted by the government, in part due to the preferences of Engineering, Procurement, and Construction (EPC) companies, which assemble solar modules, in choosing imported solar modules over domestic solar modules, which are associated with residential market expectations, resulted in the low of domestic component level value. The objective of this study is to determine the considerations of EPC companies when comparing solar modules. The analysis employs quantitative and qualitative research using Expert Choice Software through the Analytical Hierarchy Process method. The respondents came from industrial experts of solar module EPC companies in Indonesia. The study indicates that cost criteria exert the most significant influence on the selection of solar modules. It is necessary to enhance product quality criteria by increasing research and development to reduce prices and improve the competitiveness of national products.

Abstract

The primary objective of this research is to determine the factors that have an association with mandatory disclosure and stock return. This research investigated 47 manufacturing companies listed on the Indonesia Stock Exchange in 2012. Mandatory disclosure in this research used items required to be disclosed under IAS 16 and IAS 17. The data analysis used the path analysis by setting two structural equation models. The Sobel Test was used to determine whether mandatory disclosure functions as a mediator. The research proved a significantly positive association of company age with the mandatory disclosure in contrast to company size and company profitability. This implies that the investors are able to find complete and transparent information in the financial statement of mature manufacturing companies.  Moreover, company size, company profitability, and mandatory disclosure have a significant positive association with stock return. This implies that it is necessary for the companies to disclose information as required by the accounting standard in Indonesia and the investors may recognize the big and the high profitability manufacturing companies as the places to invest. However, mandatory disclosure does not function as a mediator between company size, company age, company profitability and stock return.

Abstract

Upstream oil and gas companies face simultaneous MRO inventory stockouts and overstock, reflecting misallocation rather than resource scarcity. Existing classification methods – ABC (value), VED (criticality), and ADI-CV (demand pattern) – each address only one dimension, leaving residual risk that an integrated framework can eliminate. This study applies a combined ABC-VED-ADI-CV approach to 90 MRO items at an Indonesian upstream company using 12 months of transactional data and structured expert interviews. ABC identified Class A (6% of items with 80% of cost); VED classified 54% as Vital; ADI-CV found 96% exhibiting lumpy demand, confirming that conventional forecasting is inappropriate for virtually the entire portfolio. Integrating all three dimensions identified three tubing items as highly critical – Class A, Vital, and Lumpy – whose stockout triggers immediate well shutdown. The framework offers practitioners a replicable prioritisation tool for procurement, safety stock, and supplier management.

Abstract

Program pengabdian masyarakat ini menerapkan Holistic Integrated System (HIS) berbasis 3R (Reduce, Reuse, Recycle) kepada pengelola Bank Sampah Mandiri Keluarga Harapan, kelompok Masyarakat Sadar Lingkungan, dan mahasiswa di Desa Sendangharjo, Bojonegoro. Kegiatan meliputi kunjungan edukasi ke pusat budidaya maggot Black Soldier Fly (BSF), pelatihan pemilahan sampah organik-anorganik, pengolahan sampah organik menjadi pakan maggot, integrasi budidaya ikan dan unggas, serta pemanfaatan residu ternak sebagai pupuk dalam ekosistem sirkular. Hasil pengabdian menunjukkan: (1) penurunan volume sampah organik 25–30% dalam 6 bulan; (2) produktivitas maggot rata-rata 1,5 kg/minggu per unit; (3) partisipasi aktif 75% rumah tangga; (4) peningkatan kesadaran lingkungan; dan (5) peningkatan pendapatan rumah tangga melalui produk maggot, ternak, dan tanaman organik. Program terbukti efektif sebagai model Environmental Management terpadu yang meningkatkan kapasitas pengelola bank sampah, kesadaran masyarakat, dan kompetensi mahasiswa dalam pengelolaan sampah berkelanjutan.
