Abstract

This study aims to create porous paving blocks with the addition of sengon wood powder as an alternative solution to improve the quality of soil pavement in densely populated areas. The porous paving blocks were made with a cement-to-sand ratio of 1:3, and variations in the addition of sengon wood powder P1 (2%), P2 (4%), P3 (6%), and P4 (8%) of the total material weight of 2200 grams. The resulting porous paving blocks have dimensions of 19.8 × 9.8 × 6 cm with an average weight of 1,859 g. Test results show a density of 1,341–1,921 g/m³, water absorption of 11.002–23.567%, infiltration rate of 0.069–0.146 mm/s, and compressive strength of 2.90–14.32 MPa. The composition of P1 had the best values, with an average compressive strength of 14.315 MPa and an average water absorption rate of 11%, meeting the standards of SNI 03- 0691-1996 Paving Block Grade D. This study shows that porous paving blocks made from sengon wood powder can serve as an alternative pavement material to address waterlogging in urban or densely populated areas and contribute to the utilization of agricultural waste, particularly wood powder waste

Abstract

Eggs are one of the most preferred sources of protein by people in Indonesia because of their high nutritional content and affordable prices. Purebred chicken eggs are easy to find in various places such as stalls, traditional markets, to supermarkets. Even though there is a lot of demand, purebred chicken eggs have a shelf life that doesn't last long and is easily damaged. The duration of egg storage will result in decreased egg quality so it is necessary to have a process that can extend the shelf life of the eggs, one of which is by salting the eggs. Marinated chicken eggs are made by soaking in a salt solution. However, the shelf life of the salted eggs can only last for about 3 weeks. This study aims to study the effect of coating on salted chicken eggs on shelf life, changes in weight, aroma, color, taste, and texture of salted chicken eggs. This study used a randomized block design (RBD) with 3 coating treatments and 3 coating concentration treatments, repeated 3 times. Salted eggs with tapioca flour coating treatment with concentrations of 2%, 4%, 6% can last for 13 days, 34 days, and 23 days. Then the beeswax coating treatment with a concentration of 2%, 4%, 6% can last for 20 days, 22 days, and 18 days. Then the chitosan coating treatment with a concentration of 2%, 4%, 6% can last for 20 days, 22 days and 21 days. Based on this study, it can be concluded that tapioca flour coating with a concentration of 4% had an effect on shelf life, aroma, color, taste and texture of salted chicken egg but had no effect on changes in weight.

Abstract

Free fatty acid is an important parameter in determining the quality of crude palm oil. High free fatty acid content can reduce oil quality and cause economic losses in palm oil processing. The conventional method commonly used to determine free fatty acid content is acid-base titration, but this method requires chemicals, laboratory equipment, and relatively long analysis time. This study aimed to design a portable device for rapid detection of free fatty acid content in crude palm oil using pH meter, turbidity meter, and artificial neural network. Oil samples were obtained from oil palm fruitlets with different physical damage levels. Free fatty acid content was measured using titration, while pH and turbidity were used as input variables in the artificial neural network model. The results showed that pH had a relationship with free fatty acid content with a coefficient of determination of 0.3516, while turbidity had a stronger relationship with a coefficient of determination of 0.7636. The best artificial neural network model was obtained using the tansig-logsig-logsig activation function, with R² of 0.9501 and RMSE of 0.6390 in calibration. In the testing stage, the model produced R² of 0.8061 and RMSE of 1.9222. The developed prototype can be used as a rapid method to estimate free fatty acid content in crude palm oil.

Abstract

This study evaluated the effect of ginger addition on the physical characteristics and sensory acceptance of cascara tea produced from Robusta coffee pulp. Coffee pulp is an agricultural by-product that can be processed into a value-added beverage product. Ginger was added to improve the sensory profile of cascara tea, particularly aroma and taste. The study used a single-factor Completely Randomized Design with six ginger concentrations, namely 5%, 10%, 15%, 20%, 25%, and 30% based on the weight of cascara. Each treatment was repeated three times. The observed parameters included moisture content, specific gravity, sediment content, and sensory acceptance. The results showed that ginger concentration significantly affected moisture content, but did not significantly affect specific gravity and sediment content. Sensory evaluation showed that the addition of 10% ginger produced the highest acceptance score compared with other treatments. Excessive ginger concentration tended to reduce panelist preference because the pungent ginger flavor became dominant. Based on the observed physical and sensory characteristics, the addition of 10% ginger was considered the most acceptable formulation for cascara tea made from Robusta coffee pulp. Further studies are required to analyze bioactive compounds, antioxidant activity, microbial safety, and storage stability before the product can be claimed as a functional beverage.

Abstract

This study aims to design and evaluate the performance of a simple and efficient semi-automatic cassava seed dropping system tailored to farmers’ needs. The system was constructed using mechanical components including a drive wheel, a pulley and belt transmission, and a cylindrical metering device with two dropping chambers synchronized with the rotation of the wheel. Performance tests were conducted to assess planting distance accuracy, seed orientation upon release, operational speed, field capacity, and field efficiency. The results indicate that the system operated as designed, producing an average planting distance of 80.79 cm, closely matching the intended specification. Seed orientation tests showed that 92% of the cuttings fell within an angle of 0°–15°, with an average inclination of 3.8°, aligning with agronomic recommendations for optimal shoot and root development. The tool achieved an operational speed of 0.184 m/s (0.66 km/h), with a theoretical field capacity of 0.01657 ha/h and an actual field capacity of 0.00929 ha/h, resulting in an average field efficiency of 56.10%. These findings demonstrate that the developed semi-automatic seed dropping system can enhance planting efficiency compared with manual methods while producing more uniform planting distance and orientation.

Abstract

Kegiatan pengabdian masyarakat berjudul “Revitalisasi Ekosistem Pesisir melalui Program Penanaman Mangrove dan Edukasi Lingkungan di Muara Kencana, Kendal” dilaksanakan pada tanggal 10 Agustus 2025 sebagai respons terhadap permasalahan abrasi pesisir, penurunan kualitas lingkungan, dan rendahnya kesadaran ekologis masyarakat setempat. Masalah utama dalam kegiatan ini mencakup lima masalah utama, yaitu: 1). Abrasi pantai yang semakin parah; 2). Kerusakan ekosistem mangrove; 3) Rendahnya kesadaran masyarakat pesisir terhadap konservasi lingkungan; 4) Terbatasnya kegiatan rehabilitasi yang berkelanjutan; 5) Kerentanan sosial-ekonomi masyarakat pesisir. Tujuan kegiatan ini adalah untuk mendukung upaya mitigasi abrasi dan degradasi lingkungan pesisir melalui penanaman mangrove serta peningkatan kesadaran masyarakat lewat edukasi lingkungan di Pantai Muara Kencana, Desa Pidodo Kulon, Kecamatan Patebon. Metode kegiatan meliputi metode sosialisasi dan penyadartahuan, metode partisipatif dalam penanaman mangrove, metode edukasi lingkungan, metode monitoring dan evaluasi dan metode tindak lanjut. Hasil kegiatan menunjukkan peningkatan kesadaran dan partisipasi masyarakat dalam menjaga lingkungan, terbentuknya kegiatan lanjutan seperti produksi olahan mangrove, serta rencana pengembangan wisata edukatif berbasis konservasi. Secara ekologis, kegiatan ini memperlihatkan potensi pengurangan abrasi dan peningkatan kualitas habitat pesisir, sementara secara sosial ekonomi memperkuat kapasitas masyarakat untuk berpartisipasi dalam pengelolaan lingkungan berkelanjutan.
