Abstract

Cassava production not only produces tubers, but also produces waste, one of which is cassava stems. So far, the waste of cassava stems has not been widely used by farmers, so that after the cassava is harvested, the cassava stems are just left lying on the ground. This study aims to reduce cassava stem waste through size reduction using a cassava stem chopper (Rabakong) with variations in engine speed per minute (RPM).This research was carried out at the Agricultural Equipment and Machinery Power Laboratory, Department of Agricultural Engineering, Faculty of Agriculture, University of Lampung in May - June 2023. The treatment used 3 variations of RPM namely 800, 1000, and 1400 where each used 3 different amounts of input, and each RPM was repeated 3 times. The number of inputs used is the input of 3 sticks, 4 sticks, and 5 sticks. The results showed that chopping using the RPM setting of 1400 and the input amount of 4 cassava sticks had the best working capacity with a value of 194.448 kg/hour. Lowest fuel consumption by using the RPM setting of 800 and the number of inputs of 3 sticks with a value of 1,073 liters/hour. Keywords:  Cassava Stems, Input, Rabakong, RPM.

Abstract

The availability of water in the soil varies and is influenced by soil properties, especially those related to the soil's capacity to retain water. Water retention capacity is one of the primary functions of soil, playing a crucial role in maintaining moisture and distributing water to plants. This research aims to analyze the effects of dosage and particle size of oil palm frond biochar on soil infiltration and water retention capacity. The study employed a Completely Randomized Factorial Design (RALF), comprising two factors: the dosage of oil palm frond biochar (A) and the biochar particle size (B). The dosage factor consisted of three levels: 0% (A1), 0.6% (A2), and 1.2% (A3), while the biochar particle size factor consisted of three levels: < 0.5 mm (B1), 0.5 - 1 mm (B2), and 1 - 2 mm (B3). Each experimental unit was replicated three times, resulting in 27 experimental units. The study utilized soil with silt loam texture. The research parameters observed included soil water content at field capacity conditions (pF 2.54) and at permanent wilting point conditions (pF 4.2), changes in water content over time, mass density, particle density, porosity, water infiltration, and water retention capacity. The findings revealed that the addition of biochar to silt loam textured soil resulted in a reduction in infiltration rate, with the most significant reduction observed when applying biochar with a particle size < 0.5 mm (B1). Furthermore, providing biochar with a size of 0.5 – 1 mm at a dosage of 0.6% (B2A2) and a dosage of 1.2% (B2A3) had the effect of increasing the soil's water retention capacity. Keysword : Infiltration, Factorial Completely Randomized Design, Silt Loam, Soil Physical Properties.

Abstract

The growth of development that continues to increase in each region results in reduced water catchment areas, to overcome this it is necessary to create artificial recharge. Artificial infiltration aims to preserve groundwater as a source of life to be maintained, for reasons of beauty many building service users prefer paving blocks as an alternative to pavement covering the ground surface, installations that have gaps on the sides of the paving can transmit water by 30-50% . Paving block is a building material composed of portland cement, aggregate, water, with or without additives but does not reduce the quality of the paving itself. Porous paving blocks are paving blocks made from added materials in the form of biomass waste, one of which is teak wood sawdust. This research was conducted to make porous paving blocks with quality standard D, which are used for parks floor and other uses. The composition of the materials used were cement and sand (1:3), added with teak sawdust in the treatment of P1 as much as 2%, P2 as much as 4%, P3 as much as 6%, and P4 as much as 8% of the total weight of the material 2.5 kg. Based on (SNI 03-0691-1996), paving block sizes have a minimum thickness of 60 mm with a tolerance of ±8%. The porous paving block produced meets SNI standards with side lengths of 100 mm and thicknesses varying between 56 – 72 mm. Paving blocks with quality standard D have a minimum compressive strength value of 8.5 MPa and a maximum water absorption capacity of 10%. The results of this research shown the paving block P1 treatment has an average compressive strength value of 16.05 MPa with an average water absorption capacity of 6.89% which are in paving block type D quality standard range. Keywords: Leachate, Paving Block Porous, Teak Wood Sawdust, Waste.

Abstract

Lampung Province is the largest producer of cassava in Indonesia. However, cassava production in Lampung has been declining over the past five years due to many farmers switching to other commodities due to the long harvesting period and unstable prices. This has resulted in a buildup of cassava stem waste, requiring innovation to manage this waste. Hence, the cassava stem chopper (Rabakong) was introduced. Rabakong has been developed by Agricultural Engineering (TEP) students from the University of Lampung, starting from TEP 1, TEP 2, TEP 3, TEP 4, and TEP 5. This research method involves modifying the frame of the previous version, redesigning the components to be modified using AutoCAD software, and then fabricating and collecting data after modification. The latest modified Rabakong machine underwent significant changes in the number of blades, which are fewer but arranged spirally for efficiency in chopping and space-saving. The working capacity has increased to 207 kg/hour at 1400 rpm. Waste material has decreased to 11.39%. Fuel consumption is 2.580 liters/hour. The percentage of finely chopped materials (<0.2 mm) is only 17.19%, while coarsely chopped materials (>0.5 cm) reach 51.41%, indicating that the latest version is more suitable for coarse results.. Keywords: Cassava Stems, Design, Efficiency, Modification.
