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

Corn (Zea mays) production generates a significant amount of agricultural waste, particularly corn stalks, which are often underutilized and may cause environmental problems if not properly managed. This study aimed to evaluate the performance and ergonomics of a slicer-type biomass chopper in processing corn stalks. The experiment was arranged using a completely randomized factorial design with two factors: machine rotational speed (1500, 2000, and 2700 rpm) and the number of input stalks (4, 5, and 6 stalks), with three replications for each treatment. The observed parameters included working capacity, fuel consumption, specific fuel consumption, losses, and ergonomic aspects. The results showed that the treatments significantly affected all observed parameters. The highest working capacity was obtained at treatment R3M6 (791.2 kg/h), while the lowest fuel consumption and specific fuel consumption were found at R1M4. The lowest losses were observed at R2M6 (1.118%). Overall, treatment R3M6 demonstrated the best performance by providing a balance between high productivity and acceptable fuel efficiency. Ergonomic evaluation indicated that the machine could be operated adequately, although higher operational levels may increase operator workload. Therefore, the slicer-type biomass chopper has strong potential for improving the utilization of corn stalk waste in a more efficient and sustainable manner.

Abstract

This study aimed to evaluate the performance of a multipurpose chopper machine in reducing the size of sugarcane tops as a means of utilizing agricultural biomass waste. The research was conducted at the Laboratory of Power and Agricultural Machinery, Faculty of Agriculture, University of Lampung, using a factorial Completely Randomized Design (CRD) with two factors: engine rotation speed (1500, 1700, and 2000 rpm) and feed input (3, 4, and 5 stalks of sugarcane tops). The parameters observed were work capacity, material losses, fuel consumption, and chopping uniformity. The results revealed that both engine speed and feed input had a highly significant effect on all performance parameters. Increasing engine speed enhanced work capacity up to 172.2 kg/hour, reduced material losses to 8.58%, and maintained efficient fuel consumption at 966 ml/hour under the 2000 rpm and 4-stalk combination. The multipurpose chopper machine proved to be effective and efficient in reducing the size of sugarcane tops, making it suitable for use as biomass fuel or alternative livestock feed.

Abstract

Study on drying robusta coffee beans using a solar dryer dome was conducted to support the improvement of coffee bean quality in Lampung Province. This study aims to determine and compare the effects of thickness and drying methods (solar dryer dome and sun drying) on the drying characteristics of robusta coffee beans. The parameters observed were temperature, humidity, weight loss, moisture content, and drying rate. The research results indicate that the reduction in coffee bean moisture content in the solar dryer dome occurred more rapidly than with sun drying. The drying process took 10 days using the solar dryer dome method and 21 days using the sun drying method. ANOVA results on day 10 indicate that the variations in thickness and drying methods significantly affected the moisture content of the coffee beans. LSD results show that the effects of the treatments differed significantly from one another. The treatment using a solar dryer dome with a single-layer thickness yielded the lowest moisture content at 10.2% (wet basis).

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.
