Abstract

Improper post-harvest handling of tomatoes in the supply chain can cause damage due to microorganisms. This damage has a loss on the post-harvest process of each supply chain actor. The purpose of this study is to identify the degree of damage to tomatoes due to the activity of microorganisms along the supply chain. The method used in this study is the purposive sampling method, which is to determine tomato supply chain patterns, and the Snowball sampling method to obtain the next culprit. The results obtained in this study are that there are 5 supply chain patterns in Merauke Regency. The longest tomato supply chain pattern is found in the supply chain pattern to V and the shortest pattern is in the third supply chain pattern. Post-harvest handling starts from farmers, collectors, small traders to the hands of consumers. Losses on tomatoes occurred along the supply chain by 2.07% with details at the farmer stage of 0.94%, the collector stage by 0.64%, the small trader stage by 0.49%, and the consumer stage by 0%. The isolation results obtained eight types of fungi, namely Rhizoctonia solani (45%), Fusarium sp (23%), Trichoderma sp (14%), Cladosporium sp (8%), Rhizopus (4%), Drechslera sp (2%), Stachybotrys ( 2%), Curvularia sp (2%). Based on the percentage of findings, the fungi that were the main cause of tomato fruit rot were the fungi Rhizoctonia solani and Fusarium sp.

Abstract

The purpose of this research is to design a press machine for sago flour that is in accordance with the demand for efficient sago flour production in terms of energy and time without reducing the quality of the sago flour. This research consists of; preparation stage (tool designs, proposal, provision of tools and materials includes sago flour). The second stage is making a sago flour press machine. The last stage is testing the machine, taking sago flour sample data to see the water content of sago flour and pressing time, and calculating the performance of the sago flour press on the water content of the sago flour produced. This manual sago flour press tool uses the method of a screwed iron sideways (horizontally). Based on the research, the following results were obtained: a press with a box frame with size of 50 x 50 cm, a frame leg height of 30 cm, a press plate thickness of 2 cm, a large iron tray hole with 3 cm of length and 0.5 cm of width can reduce the average content water content of 20 kg sago flour as much as 38.28% for 10 minutes. The average water content of sago flour produced after the pressing process is 22.30%. From the results obtained, this manual sago flour press can work well during the pressing process and can reduce the water content of sago flour efficiently in terms of energy and time without damaging the sago flour.

Abstract

Lettuce (Lactuca sativa L.) is a high-value horticultural commodity with promising commercial prospects. Farmers in Merauke district have not been able to cultivate lettuce crops evenly due to a variety of factors, including unsuitable climatic conditions, resulting in very limited supply of this crop commodity. The purpose of this study is to examine the effect of using some shade on the growth and yield of lettuce (Lactuca sativa L.) plants grown in a hydroponic NFT (Nutrient Film Technique) system. The research was conducted from July to September 2020 in Samkai village, Merauke, Papua. A Randomized Block Design (RBD) was used in this study. Shade variation in used as the primary tile factor, with four treatments included: without shade. Transparent roof shade, UV plastic shade, and 75% paranet shade. Blocks or repetitions as a factor of 3 subplots. The result indicated that 75% paranet shade provided the optimal plant height and root length value. UV plastic shading could increase the number of leaves and the highest safe weight of 51.13 grams. Meanwhile, transparent roof shading and without shading showed non-optimal result both in growth parameters and lettuce production.

Abstract

This research aimed to modify the rotary plow into a bed-making tool. The performance test of the bed-making tool was carried out on sandy and loamy land by experimental method. The dimensions of the bed including the length, width, and height of the bed as well as the time are also measured in the tool performance test. The bed-making tool has a total length of 182 cm, the length of the right and left sides of each was 51 cm, the width was 25 cm and the height was 30 cm. The test of the bed-making tool by a four-wheel tractor was carried out on sandy land at a distance of 10 m and a loamy land at a distance of 25 m, bed making was performed 5 times. Experimental results on sandy land showed that the average bed height was 23.6 cm; the bottom width was 80 cm, and the top width bed was 56.4 cm with a processing time of 2.12 minutes. Loamy land testing showed that the average bed height was 21.2 cm; the bottom width was 80 cm, the top width was 58.8 cm with a processing time of 4.27 minutes. Based on the test results on two different types of land, it can be seen that the tool works more effectively and efficiently on sandy land than loamy land.

Abstract

The purpose of this study was to test the modified corn sheller tool and the production capacity of the tool. Farmers do corn shelling manually by hand, so it takes a long time. The method used is a modification of a bicycle for corn shellers which can help small-scale corn farmers in the corn shelling process. The corn sheller has the main component in the form of a sheller which functions to peel the corn kernels from the cob, using a gear and chain as a drive that is related to rotating the shell which is done by a person or individual by swinging a bicycle pedal. Tool testing was carried out with 10 repetitions with each shelling using 6 corn cobs. The results showed that the production capacity of modified bicycles for corn shellers from 10 replicates showed that the lowest data was 80.18 kg/hour and the highest data was 91.29 kg/hour. Modification of the bicycle for a corn sheller from 10 repetitions on threshing corn from the cob did not find damage to the corn kernels.
