Abstract

The utilization of waste materials in concrete production is gaining significant attention as a means to mitigate environmental issues and promote sustainable construction practices. This study investigates the potential of waste glass powder (WGP) as a partial replacement for cement in concrete. The aim is to evaluate the effects of WGP on the properties and performance of concrete, with a focus on enhancing sustainability and reducing the environmental impact associated with cement production. The experimental investigation involved preparing concrete mixtures with varying proportions of WGP, ranging from 10% to 25%, as a partial replacement for cement. Based on the research findings, it can be concluded that the substitution of 20%WGP) for cement is the optimal dosage. The results of various tests and evaluations show that the concrete has desirable properties and performance characteristics at this level of replacement. This 20% substitution ratio strikes a balance between maintaining adequate compresive strength and improving the concrete's sustainability. In conclusion, the incorporation of WGP as a partial replacement for cement in concrete shows promises as an environmentally friendly and sustainable approach. Further research and optimization of mix proportions are recommended to maximize the benefits of utilizing WGP in concrete and promote its widespread application in the construction industry.

Abstract

This study aims to identify the factors that influence the performance of operational and maintenance costs in the DI irrigation network. Paguyaman. To achieve this goal, the researchers used a survey method by distributing questionnaires to a number of respondents who were involved in the implementation and monitoring of DI irrigation networks. Paguyaman. Data collection was carried out by way of a direct survey to the location and a list of questions in the questionnaire for primary data. As for the secondary data obtained from the literature and data from related agencies. Based on the results of the questionnaire from the respondents, a ranking was made of the causal factors that affect the performance of operational and maintenance costs in the DI irrigation network. Paguyaman. From the ranking results, there are 15 factors that are categorized as influential. The conclusions that can be drawn after statistical tests are that there are seven factors that influence the performance of operational costs and maintenance of irrigation networks in D.I Paguyaman. These factors are unexpected conditions and events (floods, earthquakes and others), general information and methods in carrying out operations and maintenance for field officers are inadequate, there is still a lack of responsibility for officers in carrying out irrigation operations and maintenance, changes in areas that encouraging the conversion of paddy fields to other users, the number of operational and maintenance officers is still lacking, the equipment is of poor quality and there is no training for P3A, and the most dominant factors affecting the performance of operational costs and maintenance of irrigation networks in D.I Paguyaman are conditions and events that unexpected events (floods, earthquakes, etc.).

Abstract

Glut corn is a local commodity with significant potential for development as a value-added food ingredient. However, limited product innovation, technical skills, and marketing strategies remain major challenges for Micro, Small, and Medium Enterprises (MSMEs) in Mulonegoro Village, Pulubala District, Gorontalo Regency. This community service activity aims to describe the implementation of training in the production of glutinous corn-based processed products and assess its impact on increasing the capacity of MSMEs. The method used was a qualitative participatory approach through preparation, entrepreneurship training, and practice. Participants produced product innovations in the form of glutinous corn sticks, and demonstrated readiness to market their products independently. These findings confirm that local potential-based training can strengthen MSME motivation, increase product competitiveness, and open opportunities for village economic development. In conclusion, utilizing glutinous corn through diversified processed products not only supports the sustainability of MSMEs but can also be a strategy for economic empowerment based on local wisdom. Further research is recommended to explore digital marketing strategies and partnership models that can expand the reach of glutinous corn-based MSME products.

Abstract

Pemanfaatan limbah pertanian sebagai produk bernilai tambah merupakan salah satu strategi yang dapat dilakukan untuk meningkatkan kesejahteraan masyarakat sekaligus mengurangi permasalahan lingkungan. Desa Bube Baru memiliki potensi limbah tempurung kelapa yang cukup melimpah, namun pemanfaatannya masih belum optimal dan sebagian besar hanya dibuang atau dibakar secara langsung. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam mengolah limbah tempurung kelapa menjadi arang bernilai ekonomi serta mendorong pengembangan usaha mikro, kecil, dan menengah (UMKM) berbasis sumber daya lokal. Metode pelaksanaan menggunakan pendekatan partisipatif yang meliputi survei dan identifikasi masalah, penyuluhan, pelatihan pembuatan arang tempurung kelapa, pendampingan, serta evaluasi kegiatan. Kegiatan diikuti oleh 15 peserta yang terdiri atas kelompok tani, ibu-ibu PKK, dan pemuda karang taruna. Evaluasi dilakukan melalui pre-test dan post-test untuk mengukur peningkatan pengetahuan peserta. Hasil kegiatan menunjukkan adanya peningkatan nilai rata-rata peserta dari 58,67 pada pre-test menjadi 86,67 pada post-test atau meningkat sebesar 28 poin (48,21%). Selain meningkatkan pengetahuan dan keterampilan masyarakat, kegiatan ini juga membuka peluang pengembangan UMKM berbasis pengolahan tempurung kelapa serta mendukung upaya pengurangan limbah biomassa di lingkungan desa. Dengan demikian, pemanfaatan limbah tempurung kelapa menjadi arang dapat menjadi alternatif usaha produktif yang berpotensi meningkatkan pendapatan masyarakat dan mendukung pembangunan ekonomi desa yang berkelanjutan.
