Rice is the most important staple food for humans to have energy to carry out activities. The purpose of this study is to provide information to the public in the form of a reference for selecting rice based on consumer interest, so that it can be used as a decision making in buying rice. The Mamdani method is a method that is able to solve problems in the case of rice selection based on consumer references. The work process of the Sugeno method consists of four parts, namely fuzification, inference engine, implication function amplification and the last one is defuzzification. The final result, the Mamdani method has the characteristics of using the AND operator and using the min-max value. This research is in the form of a decision-making system in rice selection based on references from consumers by looking at four aspects of criteria such as price, quality, taste, and shape variables, these four aspects can be used as a reference in rice selection. Sugeno fuzzy logic to get the final value.The Mamdani method is a very effective method in selecting rice according to the needs and interests of consumers so that potential consumers can easily choose rice according to their interests and desired criteria.

This research was made with the aim of developing the application of determining the recipient of Rastra (Rice Prosperous) aid in Tobu Village. South middle Timor district by applying the exponential comparison method. Variables or criteria used in this study are work, income, number of dependents, building area and housing conditions and detailed criteria on each variable. This research succeeded in developing an application ranking community beneficiaries of Rastra in Tobu village by using the exponential comparison method (MPE). In this application provides a graphical display feature, print reports that will be used to print and view the results of the ranking of people who are entitled to receive Sejahtera ria. 

The current state of the war against COVID-19 requires people to be active at home, keep their distance, wear masks and other healthy living habits. Almost all activities that we normally can do outside the home freely, such as school, work, play, lectures and others, have been restricted since the Covid-19 outbreak. On the other hand, of course, there are economic factors that make people continue to do activities outside the home. Seeing this situation, the acceleration of handling COVID-19 must be carried out thoroughly and involve all parties who take universities. In Ringintunggal village, residents work as farmers, usually growing rice, beans, soybeans, secondary crops, and others. But here there are also lots of crystal guavas owned by residents, so don't be surprised if we enter Ringintunggal village there will be lots of guava trees around people's homes, and there are several crystal guava gardens that are quite wide owned by residents. But with the abundance of guava fruit, it is not accompanied by the innovation of processed crystals. Therefore we saw that this was a problem in the village and we were moved to take action for the residents of Ringintunggal village by providing understanding and training on the potential assets owned by Ringintunggal village.

The sprayer is one of the equipments that is often used in agriculture, especially in rice plants to control pests and diseases. The use of the nozzle rod on the electric sprayer still uses hands resulting in the spray distance on the rice being not constant. To answer this problem, the researcher will create an innovative robotic hand holding the nozzle rod on an electric sprayer that will direct the nozzle rod constantly. Servo MG996r as a rectifier of the motion of the nozzle stem which will determine the distance and area of ​​spraying on rice. To achieve maximum dispersion in rice with a 4:1 legowo system with a servo rod length of 50 cm and a spacing between rice of 25 cm, the servo must move forward and backward at an angle of 110° - 180° which can be seen on the LCD and the distance of the nozzle rod on the object can be up and down to 38 cm and up 24 cm from the starting position. The results obtained by the robotic hand holding the nose bridge can work optimally.

Dull skin is a skin condition that is full of dead skin cells. The cause of dull skin is due to lack of water supply, pollution and sunlight and lack of facial care. Facial care can be done using a face mask. Facial masks are treatments intended to treat facial skin. Rice water is obtained from washing rice. Cherry water contains vitamins that are beneficial for skin health. Greentea has antioxidants that are good for skin health. The abundant content of EGCG antioxidants in greentea has the ability to rejuvenate damaged skin cells. The aim of this research is to create a mask based on leri and greentea water which functions to treat dull skin. The research method used is descriptive qualitative. Data collection methods used are literature, interviews, experiments and documentation. The experiment was carried out at the Laboratory of the Make-Up Study Program of the Kartini Academy of Social Welfare, Jalan Sultan Agung, No. 77, Gajahmungkur Village, Gajah Mungkur District, Semarang City. The experiment was carried out 3 times with the composition of (1) 15 grams of water powder and 10 grams of greantea, (2) 15 grams of water powder and 15 grams of grentea, (3) 10 grams of water powder and 15 grams of grenteea. From the results of these three experiments, this experiment produced a mask with a green color, coarse texture and a fresh scent of greentea.

PKM is one part of the learning process that is applied directly in the community. Which focuses on "Agricultural/Fisheries Technology Management" (Manufacture of Liquid Organic Fertilizer (POC)). Lembang Mappa' is one of Lembang whose economy lies in the agricultural and plantation sectors. Almost all residents in Lembang Mappa' work as farmers. There is one problem that has not been resolved, namely how to make organic fertilizer whose ingredients are easily available in Lembang Mappa'. The activity of socializing and making liquid organic fertilizer from gamal leaves, rice washing water, brown sugar or granulated sugar, EM4 was carried out three times with socialization to the public about how to make liquid organic fertilizer and its application to plants. After this activity, it is hoped that farmers will be able to make their own liquid organic fertilizer at home, so they can save money on purchasing fertilizer.

Many women in rural areas rely on working in the rice fields. Work in the fields is often only at the time of planting and at the time of harvest. Thus a lot of time is wasted on women. This community service activity is based on empowering rural communities through the development of soft skills in making onion crackers in Lamongan Regency to increase family income. The purpose of this activity is to empower women by providing skills that can increase family income
