Ultisol is one of the soils with limited physical characteristics. The water content is low, the permeability is not enough to pass water into the soil, and the organic-C content is classified as moderate. So that it affects the soil in storing low water, one solution to overcome the physical characteristics of is to provide organic matter into the soil. The purpose of this study was to determine the physical characteristics of Ultisol and to determine the effect of the combination of organic matter from cow dung and rice husk ash on the soil water holding capacity of ultisols on dry land. This study was conducted at the Laboratory of Wira Wacana Christian University, Sumba. This study used a completely randomized design with six treatments and four replications. Observation data were subjected to analysis of variance followed by LSD advanced test with a confidence level of 5%. The results showed that the application of organic matter on the soil significantly affected water content, field capacity, permeability, and C-organic. The application of organic matter can improve soil structure, not soil texture gave a very significant effect, and the treatment that had the best water content was 75% cow dung + 25% rice husk ash.

Moringa leaves can be processed in various food and beverage products such as clear vegetables, juice, omelette, chips, nastar, donuts, bakwan and Moringa leaf noodles. In addition, Moringa leaves can be processed as herbal drinks. Currently, with the covid-19 pandemic conditions around the world, many alternative herbal ingredients are consumed by the public to increase body nutrition in order to prevent transmission of the virus, one of which is Moringa leaves. Moringa plants are high in nutrients, such as vitamin C, calcium, vitamin A, potassium, and protein. The purpose of implementing this PkM activity is to provide information and, to provide assistance to the community in utilizing Moringa plants to prevent Covid-19, as well as to improve community skills in making Moringa herbal drink to prevent Covid-19. This PkM was held at the Ori Angu Farmers Group in Pambotanjara Village, with a series of activities including the socialization of the importance of Moringa leaves, the preparation of raw materials for making herbal moringa drinks, and the practice of manufacturing Moringa leaf herbal drink products. The results of this activity were the socialization of the use of Moringa leaves as a way to increase immunity in order to prevent viruses and the practice of making Moringa leaf tea with members of farmer groups, students and lecturers at the Ori Angu Farmer Group, Pambotanjara Village.Keywords: herbal drink; moringa leaves; prevents covid-19Abstrak: Daun kelor dapat diolah dalam berbagai produk makanan dan minuman seperti sayur bening, juice, omelet, keripik, nastar, donat, bakwan dan mie daun kelor.

ABSTRACT Quality seeds are the main factor in supporting the success of production in agriculture. East Sumba has one of the local varieties of peanuts called “Walakari”. However, the problem is that there is a decrease in yield among farmers caused by the quality of the seeds used having decreased. Seeds that are stored for too long will experience seed deterioration. The aim of the study was to determine the quality of the local variety Walakari peanut as a typical bean of East Sumba through seed health and electrical conductivity tests to see the level of leakage of the seed membrane. The study used a completely randomized design with 10 treatments, 2 replications consisting of P0 (control), P1 (coconut water immersion 50ml/L aquadest), P2 (coconut water immersion 150ml/L aquadest), P3 (coconut water immersion 250ml/L aquadest) , P4 (betel leaf extract immersion 50ml/L aquadest), P5 (betel leaf extract immersion 150ml/L aquadest), P6 (betel leaf extract immersion 250ml/L aquadest), P7 (50ml/L aquadest chili extract), P8 ( 150ml/L aquadest chili extract, P9 (250ml/L aquadest chili extract). The results of the seed health test showed that the Walakari variety was included in the moderate to severe infection category. However, with the immersion treatment of local ingredients, betel leaf extract was able to suppress the spread of disease-causing microorganisms up to 96%. Meanwhile, the results of the membrane leakage test using the conductivity test showed that the average value of the electrical conductivity of Walakari variety peanut seeds in all treatments was included in the high category, except for the betel leaf extract soaking treatment. High conductivity values ​​indicate low seed vigor.
