Abstract

Indonesia is one of the largest tea producing countries where dry tea production is exported to various countries. The tea industry absorbs a lot of labor both from the area around the tea garden and from outside the garden area. Tea pickers are workers who really need their existence, considering the quality and quantity of tea depends on how they work. The wages of tea pickers are very low due to the small amount of picking weight produced because the picking system is still done manually. The purpose of this study was to determine the effect of manual picking mechanization and using scissors on the wages earned by pickers. Sampling was done randomly and analyzed using multiple linear regression. The results showed that there was a significant difference between the picking system and the wages of the pickers. The use of picking scissors can increase wages by 40.18%. The increase in pickers' income is expected to be able to motivate pickers to work optimally to increase the welfare of Wonosobo tea pickers.

Abstract

This study aims to determine the right temperature and extraction time to get the best yield and quality of pectin from lime peel. It is hoped that the results of this study can become a reference for studying and utilizing lime peels as a pectin producer. This research was carried out at the Food Technology Laboratory, Faculty of Agriculture, University of Sam Ratulangi. This study used a completely randomized design (RAL) with 2 factors, namely extraction temperature (60, 70, and 900C) and extraction time (40, 60, 80, and 100 minutes) with 3 replications. The results showed that the yield of orange peel pectin lime ranged from 3.1826% to 5.2211% wet weight. The highest yield of pectin was produced and the extraction temperature was treated at 900C for 100 minutes. The methoxy content ranges from 7.1706% to 8.3534% so that it is classified as a high methoxyl content pectin, the pectin water content ranges from 9.734% to 13.7703% while the ash content ranges from 1.8009% to 2.5339%. From these results it was concluded that the best conditions for extracting lime peel pectin were at 900C with an extraction time of 100 minutes and lime peels could be used for commercial processing of pectin.

Abstract

One factor affecting productivity is the quality of seeds with good initial seed vigor indicators, but less than optimum growing environment conditions also affect seeds' growth and initial Vigor. One of the technologies that can improve it is giving priming treatment to the seeds before planting. This study aims to see the effect of priming treatment to improve the quality of Vigor and early growth of 2 composite corn varieties, namely Sukmaraga and Bisma. The research was carried out in the laboratory and the Green House, with the experimental method using a Completely Randomized Design (CRD) with each seed of the two varieties treated with Hydropriming (soaking seeds before planting) using Ion-Free Water (IFW) for 30 minutes, 12 hours, and 24 hours plus a control treatment without Priming, and priming using PGR made from sodium orthonitrifenol 0.2%, sodium 2,4-dinitrophenol 0.05% both as controls. So there are a total of 10 treatments. The results showed that priming treatment greatly influenced the germination, where all Hydropriming treatments gave average germination above 88%, significantly different from seeds without priming below 82%. The hypocotyl length ratio of Sukmaraga and Bisma corn seeds was also different from the treatment without priming. Seeds with hydropriming for 12 hours showed the best field growth percentage, reaching 96.7% (Sukmaraga variety) and 96.98% (Bisma variety).

Abstract

The scoop net, also known as Sodo', is a type of fishing gear commonly used by fishermen in the waters of Mallusetasi, Barru Regency. Unlike commercial fishing gear, the scoop net is an alternative method of fishing. This study aims to analyze the oceanographic parameters of the fishing area and the composition of the catch obtained using the scoop net in the Mallusetasi waters of Barru Regency. The research was conducted from May to September 2021, using survey methods such as observation, interviews, and documentation. Data on oceanographic parameters of the fishing area, catch composition, gear construction, and operational stages of the scoop net were collected and analyzed using descriptive methods. The findings were then tabulated to facilitate data interpretation. The results of the study showed that the oceanographic parameters in Mallusetasi waters, including temperature, salinity, current velocity, and depth, were suitable for operating the scoop net, particularly for targeting the primary catch of anchovies (Stolephorus Sp.) that can be caught at any time. However, the peak season for catching Medan anchovies (Stolephorus waitei) and Nasi anchovies (Stolephorus commersoni) occurs during the eastern season, specifically in July to August. As for the rebon shrimp (Acetes sp.), the catching season occurs in May.
