The Information technology development has affected various sectors, including health services. The several technologies have been used to improve health facilities performance. At Johar Baru Health center, central Jakarta, SIKDA (Sisitem Informasi Kesehatan Daerah) Optima application has been applied. Meanwhile, the implementation of SIKDA Optima is not as good as expected. There still many disruptions during the use of this application such a delay service and delivery of report was not in a real time, therefore an evaluation is needed. The purpose of this study was to determine the quality of system, information, and service which is affecting the satisfaction of SIKDA Optima users at Johar Baru Health Center, Central Jakarta. This study used a quantitative approach with observational survey and cross-sectional design. The population in this study was 98 persons and the sample were 79 users of SIKDA Optima, consist of 19 doctors, 22 nurses, 17 midwives, 9 pharmacies, 2 medical recorder and 10 administration staffs. Data analysis was performed using multiple linear regression. The results of multiple linear regression test showed that the user satisfaction of SIKDA Optima = -3.832 + 0.549 (KS) + 0.757 (KI) + 0.359 (KL) with a p-value of KS 0.001<0.05), p-value KI 0,000 <0,05), and the p-value of KL is 0.009 <0.05. The conclusion of this study is the quality of system, information, and services that is used at Johar Baru Health Center have a significant influence on the satisfaction of SIKDA Optima users.

Rainfall which is occurred in an area explain the Onset Rainy Season (ORS). ORS is a characteristic of the rainy season which is important to know, but the characteristics of the rain itself is very difficult to predict. We use the method of Fuzzy Inference System (FIS) to predict ORS. Unfortunately, FIS is weak to determine parameters so that influences the working FIS method. In this study, we use PSO to optimize parameter of the FIS method to increase perform of the FIS method for onset prediction of the rainy season with the predictor Sea Surface Temperature Nino 3.4 and Index Ocean Dipole. We used coefficient correlation to determine the relationship between two variables as predictors and RMSE as evaluate to all methods. The experiment result has shown that the work of FIS-PSO after optimizing produced the good work with the coefficient correlation = 0.57 and RMSE = 2.96 that is the smallest value that is better performance if compared with other methods. It can be concluded that the method proposed can increase the onset prediction of the rainy season.

The number of cases of Corona Virus Diesis (COVID-19) according to the World Health Organization (WHO) is 93,217,287 people. In the case of Covid-19, one of which is making changes in behavior is education. The teaching and learning process has changed into bold learning in the education sector. Students who continuously carry out the learning process at home can increase stress because previous research data stated that the level of severe anxiety experienced by students was one of them caused by daring learning, which reached 95.59%, and students reached 97.69%. This research aims to develop an expert system for dealing with stress in high school students. The method used for making the expert system is the Certainty Factor. Based on functionality testing using black box testing, it shows that all components produce the expected and appropriate results, then for accuracy testing using a confusion matrix through a comparison between manual calculations and system calculations, so that the accuracy test results are 100%. Therefore, the expert system for diagnosing stress diseases in high school students can be said to be feasible.

Media pembelajaran merupakan salah satu komponen yang perlu ada dalam rencana pembelajaran, media pembelajaran yang berhasil adalah yang dapat mengubah perilaku peserta didik (behavior change) serta meningkatkan hasil belajar peserta didik tertentu. Keberhasilan penggunaan media pembelajan tidak terlepas dari bagaimana media itu direncanakan dengan baik. Penggunaan media yang efektif diperlukan analisis yang komprehensif dengan memperhatikan berbagai aspek, antara lain tujuan, kondisi peserta didik, fasilitas pendukung, waktu yang tersedia, dan kemampuan guru untuk menggunakannya dengan tepat. Permasalahan yang ada saat ini adalah kurangnya pengetahuan dan kemampuan para guru SMPIT Insan Rabbani dalam penggunaan dan pemanfaatan media pembelajaran berbasis multimedia merupakan media pembelajaran yang memanfaatkan penggabungan antara gambar, suara atau audio, dan video. Tujuan pelaksanaan pengabdian kepada masyarakat ini adalah untuk pengenalan dan pelatihan terkait pembuatan video pembelajaran dengan menggunaan aplikasi camtasia sebagai upaya untuk menggunakan media pembelajaran yang lebih efektif dalam rangka meningkatkan minat belajat siswanya. Kegiatan pengabdian kepada masyarakat ini pelaksanaannya menggunakan metode Community Based Participatory Action Research (CBPAR). Hasil kegiatan ini menunjukan peningkatan pemahaman pengetahuan dan ketrampilan sebesar 38% tentang aplikasi Camtasia penting bagi para guru untuk meningkatkan kompetensinya dalam membuat media pembelajaran berbasis multimedia sebagai upaya meningkatkan minat belajar siswa.

The development of social media today makes changes to marketing methods. Marketing using social media is a cheap solution and does not pose a high risk for the users. With social media, it can be used a way to increase brand awareness. An effective digital marketing media is needed to increase brand awareness, one of them is Facebook ads. In the education sector, facebook ads are still rarely used, generally schools use conventional marketing methods, this method has weaknesses, such as: limited scope and inefficient marketing costs. Marketing used conventional methods is considered ineffective, it occur at out by BPAI School in 2019 only 10% of potential consumers contacted the school. The small number of marketing effectiveness is the influence of the low brand awareness of the BPAI School, therefore innovation is needed in marketing to increase brand awareness, it is by using facebook ads. The results of the implementation of facebook ads at BPAI School for 5 days concluded that facebook ads had significant effect in increasing brand awareness
