Diagnosis of autism spectrum disorder (ASD) can use a fuzzy inference system. The use of fuzzy logic method to obtain ASD diagnosis results according to experts based on the limits of factors/symptoms of the disease and all the rules obtained from experts. Recommendations for therapy and preventive actions can be given by experts after knowing the results of the diagnosis of ASD using the fuzzy logic method. This study serves to diagnose ASD by optimizing each degree of membership in the fuzzy logic method with the Mamdani method approach which is involved in the autism detection process involving 96 patient data. The Mamdani method itself can process an uncertain value from the user/patient into a definite value whose membership degree can be determined and adjusted to the conditions of the problem. Optimization was carried out on the degree of membership for all variables involved in the process of diagnosing ASD, namely social interaction, social communication and imagination and behavior patterns. The results of this study indicate a relatively small level of fuzzy calculation error with a precision value of 94.4%, a recall precision value of 65.4% and an error rate value of 3.05%. Calculation of accuracy shows a result of 90.59%.

Decreased appetite is a health problem that often occurs especially in children. Various ways of being taken by parents to solve the problem, either through drugs or pharmacology and nonfarmochology in the form of herbal-banquets based Temulawak. Temulawak is one of the spices produced in Cilacap regency that has not been utilized optimally. During this time, Temulawak is processed in a form of powder and made in beverage packaging. Temulawak Chocolate is an innovation that we develop to utilize Temulawak while addressing health problems in the form of decreased appetite. Because if the problem is not handled immediately, it can result in less nutrition or even poor nutrition. COMUT (cute Temulawak chocolate) is an innovation that we have developed to address the problem. The goal of community service is to implement COMUT in children and toddlers in PAUD Amanah Cilacap as an effort to increase appetite. The method used is a pretests post test one group, measuring the appetite level using the quesioner before and after given treatment of chocolate Temulawak. The results of community service is a change of appetite between before being given Temulawak chocolate and after given Temulawak chocolate. The result of Quesioner counting of 30 samples showed that the average score before given the Temulawak chocolate amounted to 29.4 and after the average COMUT was given to 35.1. As for the development of food from a portion of rata2 increases and snacks increase.

Preeclampsia is a disease of pregnant women, causing many complaints, including dizziness. Massage is the right solution to reduce dizziness since the use of analgesic drugs is not recommended. Submission of massage information can be more effective through digital technology. The purpose of this research is to build an application based on Augmented Reality (AR) as a guide for facial massage movements for midwives and pregnant women to deal with complaints of dizziness for pregnant women. The method used is the Multimedia Development Life Cycle (MDLC), which consists of the stages of making a concept, making a design, collecting materials, combining materials, testing, and distribution. Black box testing on 10 scenarios produces a value of 100%, which means the application can run properly. In addition, usability testing using the System Usabilities Scale (SUS) method shows a value of 69.5, which means that the application has the "good" criteria and is acceptable to users.
