Eggs as a staple food for the community are increasingly in demand because they are very easy to obtain, easy to process and have high protein content. Duck eggs stored at room temperature can only last 10-14 days, after which the eggs have decreased in quality. The purpose of this study was to determine the effect of using betel nut seed solution as a preservative on the storage time and quality of duck eggs. This type of research is a True-experimental study with a Completely Randomized Design (CRD), two factorial, consisting of concentration treatments (0%, 15%, 30%, 45%, and 60%) and storage time treatments (14 days, 21 days, and 28 days) with 3 replicates. Chemical and physical test data were analyzed using the ANOVA test (5%) using SPSS for Windows version 20.0. The interaction of betel nut seed solution concentration and storage time gave no significant effect on the pH value (Fhit = 1.125 < Ftab = 1.375), Yolk Index (Fhit = 1.002 < Ftab = 1.454), and Weight Loss (Fhit = 0.614 < Ftab = 0.638). However, the length of storage of duck eggs had a significant effect on the yolk index (Fhit = 21.821 > Ftab = 21) and weight loss (Fhit = 12,569 > Ftab = 12.001).

The objectives of this service activity are: 1) to introduce and train the abilities of students of the Department of Biology Education, Faculty of Applied Science and Engineering, Mandalika University of Education in plant cutting techniques in an effort to propagate hypoestes plants; and 2) teach which practical science is faster, the growth of hypoestes roots immersed in well water or B1 mixed water. Service activities are carried out within 1 day (plus follow-up activities in the form of observations for 3-6 days at each home). The stages of this service activity are: 1) introduction; 2) cutting practice activities; and 3) follow-up activities (observations). One day activity is devoted to the practice of cutting techniques, then the cut plants are immersed in water to observe root growth (observation for 3-6 days). Based on the results of the activity evaluation, it can be concluded that the purpose of this service activity has been achieved in accordance with expectations. This achievement can be seen from the student's ability to cut hypoestes plants, and students are able to grow the roots of the cut plants after 6 days of immersion.

The purpose of this activity is to increase the knowledge and skills of the community in utilizing livestock and community plantation waste into compost. The advantages of this compost are that it is environmentally friendly, can increase the income of farmers and can increase soil fertility and improve soil physical damage due to excessive use of inorganic fertilizers. The participants of this training activity were 21 people from Selelos Baturinggit Village, Gangga District, North Lombok Regency. This training activity is carried out in three stages, namely: 1) Preparation; 2) Implementation; and 3) Evaluation. The implementation of this community service program is by providing a technology package for making solid organic fertilizer with the basic ingredients of cow dung and community plantation waste. Extension activities and practices for making solid organic fertilizers have been carried out in the Selelos Baturinggit Village Community, North Lombok Regency. The results of this organic fertilizer are expected to be applied to plantation land to reduce the use of inorganic fertilizers and increase plantation yields.

Red dragon fruit is an immigrant fruit that is liked by many people because it has content and properties that are quite good for health. The production of red dragon fruit from year to year will increase, so that at harvest time the price will drop drastically from usual. On the other hand, red dragon fruit cannot be stored for too long, so in this study an attempt was made to make jam from red dragon fruit flesh mixed with Moringa leaf extract. Moringa leaf extract used has tannin compounds that are useful in food products to extend the shelf life of a food. The purpose of this study was to determine the effect of adding Moringa leaf extract (Moringa oleifera) on organoleptic tests and the shelf life of red dragon fruit jam (Hylocereus polyrhizus). This study used a randomized block design (RAK) consisting of 6 treatments with 4 replications, with different concentrations of Moringa leaf extract, namely (K = 0 ml, P1 = 5 ml, P2 = 15 ml, P3 = 25 ml, P4 = 30 ml, P5 = 50 ml. Based on the results of the study, it was found that the organoleptic test results of red dragon fruit jam (Hylocereus polyrhizus) had an effect on the level of aroma and taste, but had no effect on the color level of the jam. The shelf-life test of red dragon fruit jam (Hylocereus polyrhizus) was able to persisted for 4 days, after the 5th day some of the treatment samples were found to be moldy and after the 7th day almost all red dragon fruit jams were found to be moldy with the number of fungi growing more and more, so that the addition of Moringa oleifera leaf extract was not able to prolong the durability save the red dragon fruit jam (Hylocereus polyrhizus).
