Abstract

Sweet potato is included in the type of palawija plant. Sweet potato (Ipomoea batatas L.) is a source of carbohydrates and sweet potato is widely consumed as a staple food to replace rice. Cilembu Village, Pamulihan District, Sumedang Regency is a center to produce Cilembu sweet potato which has been exported to several countries. Cilembu sweet potato production, especially in the washing process of Cilembu sweet potato, can reach 30 kg/hour. However, the washing process is still done manually in a sitting and bowing position. To increase the cleaning capacity of Cilembu sweet potato, a Cilembu sweet potato washing machine was made. The machine has been modified, but the machine that has been modified needs to be analyzed for its ergonomic feasibility. The purpose of this study was to perform an ergonomics analysis on a modified Cilembu sweet potato washing machine to make it suitable for mass marketing. The method used in this study is a descriptive analysis research method, namely measuring, observing, and calculating the modified sweet potato washing machine and then analyzing the data to obtain machine ergonomics feasibility data. The results showed that the analysis of anthropometric data on machine height was appropriate because the machine height did not exceed the calculated value of the 2.5th percentile, but for machine width there was still a difference between the machine width and the operator's shoulder width because the machine width was smaller than the shoulder width. 50th percentile. The results of the analysis of work postures using the REBA method found 3 postures with a moderate risk level of safety, 2 postures with a high level of security and 1 with a negligible level of safety. On noise and vibration measurements it was found that the machine could only be operated for 3 hours in one day.

Abstract

Hydroponic model SWU-01 is a new hydroponic system innovation that regulates watering automatically and independently by utilizing gravity and Archimedes' law. Dissolved oxygen concentration in SWU-01 is only around 3-4.2 mg/L. DO values can be increased by applying nanobubble technology. Ultrafine bubble or nanobubble is a gas bubble in a liquid that has a diameter of <200 nm. The purpose of this study was to determine the effect of nanobubble on dissolved oxygen concentration and growth of lettuce plants cultivated with SWU-01 hydroponics. The experiment used a one-factor randomized complete block design, namely intermittent administration of nanobubble for 15 min every 3 day (P1) and 7 days (P2), and without nanobubble (P0l). The results obtained based on the ANOVA test at the 5% level with the Least Significant Difference (LSD) follow-up test, namely the parameters of fresh weight and number of leaves of lettuce P1 significantly different from P0 and P2, and no significant differences were found in root length, canopy width, and plant height. The P1 treatment is more effective in increasing dissolved oxygen concentration, leaf count, and fresh weight of lettuce produced in lettuce cultivation using the SWU-01 hydroponic system. Keywords: Dissolved oxygen, Hydroponics, Lettuce, Nanobubbles, Plant growth.

Abstract

The greenhouse plays a pivotal role in creating an ideal environment for hydroponic cultivation. The greenhouse has utilized rainwater and basin water as a source of raw water for hydroponic farming. Presently, the water quality of Leuwi Padjadjaran basin fails to meet the standards required for hydroponics due to its turbidity, sediment content, discoloration, pH levels exceeding 7, and low dissolved oxygen (DO) concentration of 2.2 mg/l. The micro/nanobubbles (MNBs) technology stands as a viable method for water treatment owing to its capacity to bind impurities via radical OH. The application of MNBs for the treatment of basin water involves the use of a hydrodynamic cavitation MNBs generator with a dual-chamber rotating flow nozzle. The parameters evaluated in this research encompass DO concentration, MNBs stability, microbubble size, and the visual response to MNBs application. MNBs treatment was conducted with three different gases: air, oxygen, and ozone. Microbubbles were measured using the particle image velocimetry (PIV) method. The DO concentration reaches 21.6 mg/l when employing oxygen-based MNBs. On the third day post-generation, MNBs stability still maintains DO concentrations above the initial levels. Thus it can be used as hydroponic raw water.  Keywords:  DO concentration, Greenhouse, Micro/nanobubbles, Water treatment.

Abstract

Manual rice threshing can result in up to a 10% grain loss because the rice grains are not gathered at a single point. Another drawback of manual threshing is that not all rice grains are separated from their husks due to the need for high-pressure strikes. Additionally, farmers, especially women, often complain of back pain because rice threshing work is carried out all day during the harvest season. To reduce the workload and fatigue experienced by rice farmers in Cipunagara District, Subang Regency, the objective of this Community Service Program (PKM) is to introduce rice threshing machines to partner groups. The method involves implementing rice threshing machine technology, including the allocation of 2 (two) fully mechanical rice threshing machines developed by the Agricultural Machinery Laboratory of Unpad. The accompanying mechanism and socialization involve lectures on post-harvest rice processing, specifically rice threshing, instructions on operating and maintaining rice threshing machines, and concluding with discussions. The results of this PKM show increased farmer knowledge regarding post-harvest rice processing, particularly rice threshing, with reduced grain loss (<2%), shorter threshing time (1 HOK), and a threshing machine capacity of 500 kg/hour.
