Abstract

Water hyacinth is a waste in waters that can damage the balance of aquatic ecosystems because of its rapid growth, which can reach 3% in a day. One utilization of water hyacinth waste is to be used as filler material for decorative particleboard. This study aims to look at the physical and mechanical characteristics of particleboard with surface coating treatment using silane coupling agent solution.. Water hyacinth fiber was selected as an alternative filler material for the particle board composite due to its abundant availability and potential fiber properties. The surface of the particle boards was modified using a silane coupling agent (KH550) to enhance the bond quality between components. The water hyacinth powder was first alkalized with NaOH and distilled water (1:5) for 1 hour, then mixed with epoxy resin in a 40:60 weight ratio. The compaction process was carried out using a hydraulic hot press at 2 bar pressure and 50°C temperature for 10 minutes. The resulting particle boards were tested for density, moisture content, water absorption, and thickness swelling. Flexural testing was conducted in accordance with ASTM D790-03, and tensile strength testing followed ASTM D638-14. Surface morphology was observed using a scanning electron microscope (SEM). The results showed that the application of a silane coupling agent improved the bond between the matrix and filler, and the produced particle boards met the quality standards for density, moisture content, water absorption, thickness swelling, flexural strength, and tensile strength.

Abstract

Rice is one of the agricultural commodities in South Sumatra whose productivity level still fluctuates. In 2000, rice production reached 1,863,643.00 kg, then increased to 3,272,451.00 kg, in 2010, but decreased again in 2020 to 2,696,877.46 kg. This instability is influenced by various factors such as land area, rainfall, pest attacks, and fertilizer use. This study aims to optimize rice production by applying machine learning using multiple linear regression algorithms, and the CRISP-DM method, with the stages being business understanding, data understanding, data preparation, modeling, evaluation, and implementation. Data of 1,000 records obtained from farmers were analyzed using Google Collaboratory, resulting in an intercept of -3836,2639, and coefficients for land area of 5,7336, rainfall of 1,2710, pests of 6,1153, urea of 1,6226, and phonska of 1,2581. To evaluate the accuracy of rice production predictions based on these independent variables, calculations were made on the RMSE value and analysis of the coefficient of determination. The results were that the RMSE value was recorded at 17065084,9641, and the coefficient of determination (R²) was 0,6487, indicating that around 64,87 % of the variability in rice production can be explained by independent variables such as land area, rainfall, pest attacks, use of urea fertilizer, and phonska, while the remaining 35,13 % was influenced by other factors.

Abstract

The riparian zone of the Barito River is an important ecosystem, yet its utilization patterns by indigenous communities in the area remain relatively limited. The lack of comprehensive data may hinder efforts in documentation, conservation, and the management of biological resources based on local wisdom. This study aims to document the diversity of plant species used by the Dayak Bakumpai community along the banks of the Barito River in Sungai Gampa Village, Barito Kuala Regency, South Kalimantan. The research will be conducted from August to September 2025 using a descriptive exploratory design with both qualitative and simple quantitative approaches. Data will be collected through field observations using an exploration method to record morphological characteristics of roots, stems, leaves, flowers, and fruits. The results identified nine plant species, namely Syzygium aqueanum (water apple), Syzygium polyanthum, Syzygium malaccense (L.) Merr., Psidium guajava (red guava and white guava), Melaleuca cajuputi Powell (large-leaf and small-leaf galam), and Melastoma candidum, with the genus Syzygium dominating in terms of species number. The utilization of these plants by the community includes fruit as a food source, traditional medicine, and essential oil production, demonstrating the close relationship between riparian plant diversity and the socio-economic needs of the local community. This inventory provides baseline data on the riparian flora of the Barito River, which is valuable for biodiversity documentation, vegetation monitoring, and community-based riparian area management.

Abstract

ABSTRAKUsaha (mikro) kecil menengah di Indonesia merupakan bagian penting dari sistem perekonomian nasional karena berperan untuk mempercepat pemerataan pertumbuhan ekonomi melalui misi penyediaan lapangan usaha dan lapangan kerja dan peningkatan pendapatan masyarakat. Penelitian ini mengeksplorasi penerapan akad mudharabah dalam perspektif usaha mikro, kecil, dan menengah (UMKM). Mudharabah merupakan salah satu akad syariah yang bersifat profit-sharing antara pemilik modal (shahibul maal) dan pengelola usaha (mudharib). Metode penelitian yang digunakan adalah pendekatan kualitatif fenomenologis dengan studi kasus pada tiga informan pelaku UMKM yang bekerja sama dengan fakultas ekonomi dan bisnis universitas khairun. Hasil penelitian menunjukkan bahwa akad mudharabah memiliki potensi besar dalam meningkatkan kapasitas usaha UMKM, namun masih terdapat kendala dalam implementasinya seperti kurangnya literasi keuangan syariah dan ketidakpastian dalam pembagian keuntungan. Penelitian ini merekomendasikan peningkatan edukasi dan literasi mudharabah bagi pelaku UMKM dan pembentukan sistem monitoring yang akuntabel.Kata Kunci: Mudharabah, UMKM, Fakultas Ekonomi dan BisnisABSTRACT Micro, small, and medium enterprises (MSMEs) in Indonesia are a vital component of the national economic system, as they contribute significantly to promoting equitable economic growth through their role in creating business and employment opportunities and increasing community income. This study explores the application of the mudharabah contract from the perspective of MSMEs. Mudharabah is a Sharia-based financing contract that involves a profit-sharing agreement between the capital provider (shahibul maal) and the business manager (mudharib). The research method employed is a qualitative phenomenological approach, with a case study conducted on three MSME actors collaborating with the Faculty of Economics and Business, Khairun University. The findings reveal that mudharabah has great potential to enhance the business capacity of MSMEs. However, challenges remain in its implementation, including limited Islamic financial literacy and uncertainties in profit-sharing arrangements. This study recommends increasing mudharabah-related education and literacy for MSME actors and establishing an accountable monitoring system.Keywords: Mudharabah, MSMEs, Faculty of Economics and Business
