Kale spinach is a type of vegetable that is widely consumed by people in Indonesia. It’s contains protein, carbohydrates, calcium, iron, sodium, phosphorus, fiber, vitamins A and C. The kale spinach is a low-calorie vegetable. The purpose of this research is to design kale spinach seed planting tool with a semi-mechanical system which power comes from human power, this tool is operated by pulling a lever on the tool so that the tool can work. After the manufacture of kale seed planting is complete, the authors test the performance of the tool capacity, and from the results of the performance test of this tool it can be concluded that it can work well. The results of the performance test of the capacity of this tool to plant water spinach seeds with an area of 0.0005 ha takes 0.007 hours with an average speed of 0.2 m/s, the average seeds that fall per hole are 3 seeds, 98.6% efficiency, The theoretical capacity is 0.072 ha/hour, the effective capacity is 0.071 ha/hour, the percentage of growth is 95%, the average distance between plants is 10 cm, and the average distance between rows of plants is 10 cm.

Increasing the heat energy in the evaporator box from the Water Solar Destiler, by adding a wire heater aims to increase the heat energy in the evaporator box so that it will speed up the evaporation process in the evaporator box. The more liquid that is broken down due to heat energy into water vapor, the more discharge will be produced. Based on the results of the observations made, the addition of a wire heater in the evaporator city with AC electricity generated by solar panels, increased the purified water by 248.78%, from 1745 ml to 4341 ml, with the thickness of the water being purified as thick as 1 cm which was dried in the sun. for 10 hours starting from 07.00 WIB to 17.00 WIB.

The limited quantity and types of facilities for practicum, independent business projects and research, both lecturer and student research, is a problem that often arises and requires solutions to overcome it, one way to overcome the problem of limitations in types of practicum facilities is to modify existing equipment so that it can be done. used for other functions in accordance with the demands of the development of student and lecturer research studies. Modification of an ordinary oven into a vacuum oven is a set of drying ovens that are coupled with a suction pump and equipped with a vacuum gauge to measure the level of vacuum. A vacuum oven is a drying device with a low temperature, with the working principle in a vacuum that the boiling point of moisture is lower than the boiling point in atmospheric conditions so as to speed up the drying time and reduce the amount of damaged nutrients in the dried material due to drying. This drying method is suitable for materials that have high temperature sensitivity or are volatile due to their short drying time, one of which is food ingredients. At high temperature drying, the vitamin content in food is easily degraded and damaged. The modified vacuum oven can be used to dry materials from the types of leaves, fruit and tubers that were thinned using a temperature of 60°C, a vacuum level of -0.5 atm for 2 hours.

The Bina Sarana Bakti Foundation (YBSB) implements an organic farming system, which is an agricultural management system with a terrace design with permanent beds that can ecologically (environmentally) improve land quality, provide stable and sustainable yields and income into the future. To provide water for plants so that organic farming can take place throughout the season, both in the rainy season and in the dry season, water reservoirs are built using existing water sources. Utilization of water in the cultivation of organic lettuce at the Bina Sarana Bakti Foundation is carried out with 2-level irrigation hose treatment, namely the interval of providing irrigation water for 3 days and 4 days. Data analysis used t test at 5% real level. The results showed that the theoretical amount of water for lettuce at the Bina Sarana Bakti Foundation was 714 l/bed/season which was almost the same as the actual water use of lettuce with an interval of 3 days of irrigation water including additional liquid fertilizer from rabbit urine. + water in open land in shade is 720 l/bed/season, however, it is much lower than the interval of providing irrigation water for 4 days in open land without shade, namely 4,980 l/bed/season. The production of lettuce in shade with an interval of 3 days of 30.4 kg/bed/season was much greater than the production of lettuce without shade with an interval of 4 days of irrigation water, which was only 24.7 kg/bed/season. The productivity of irrigation water for shaded lettuce with the provision of irrigation water at an interval of 3 days of irrigation is 42.22 kg/m³, much higher and more effective than lettuce without shade with an interval of 4 days of irrigation which is only 4.96 kg/m³. Keywords: irrigation time interval, lettuce plants, no shade, shade, and water productivity.
