Abstract

Currently, many parents want their children to be free from disease. Although this cannot be fully expected. Problems that often occur to parents are when their child is sick, lack of knowledge and limited sources of information about the disease that causes parents to leave their children without first aid. In other conditions, in areas that are far from the doctor's practice, the need for information on disease management is very necessary. Based on the problems that have been described previously, this expert system was created to assist parents in understanding the symptoms of skin diseases that occur in children. In the development of this expert system using the Best-First Search (BFS) algorithm as an inference engine. In this expert system application the user can choose the symptoms of the disease in children, then the output produced is the conclusion of the disease. From the test results based on Blackbox, it was found that 100% functionality runs according to the list of system requirements. After this research was completed, it was concluded that to design an expert system in detecting childhood diseases, starting from conducting interviews, followed by system design, the next process was implementing the system, then testing by experts for compatibility with the data that had been obtained.

Abstract

Content Delivery Network (CDN) is a server system network to content contribution in an application/web to various accessors around the world so that data sent and received by users was faster. Server selection algorithm determines the extent to which the quality of server service to client requests. This study to analyze  CDN performance, used Geographical algorithm Domain Name Server (GeoDNS), Round Robin (RR), Weigthed Round Robin (WRR), dan Least Connection (LC). In addition, Rateless Code (RLC) is also applied to reduce packet loss, there are two methods used, namely the first method is rateless code 50 and the second method is rateless code 100. Thus, the trial was carried out 20 times. Besides that, it is also applied Rateless Code (RLC) to less packet loss. From the research results, the use of CDN can improve server service performance. CDN managed to reduce the maximum to the average delay about 67,6%. From the studied CDN algorithm, Geo DNS experienced the lowest delay up to about 67.6 ms, however LC experienced the lowest packet loss, namely about 2,84%. The application of rateless code on CDN with LC algorithm succeeded in reducing packet loss to about 2.84%, but delay increased to about 75.3%.

Abstract

Sexual violence is an act of intentionally insulting, degrading, harassing, or physically assaulting someone, which can harm someone. This outreach program aims to increase students' knowledge of sex education and how adolescents can prevent sexual harassment. This community service program uses the Participatory Action Research (PAR) method, a method that involves engaging with students. This activity is carried out directly, starting with observation, coordination, and obtaining permission from the local school principal regarding the activity plan. This includes arrangements regarding the availability of space, time, and participants. The material presented relates to insights into sexual violence, types of sexual violence, the impacts of sexual violence, and laws that regulate and protect victims of sexual violence. The role of schools in preventing sexual violence and protecting students' human rights has not been optimally implemented due to the lack of specific regulations and the formation of an anti-violence task force. Furthermore, school efforts also lack a structured handling process. Therefore, it is necessary to provide education and knowledge regarding the laws that regulate and protect victims of sexual violence. The results of this activity show an increase in knowledge, affective skills, and understanding regarding cases of sexual violence because preventing sexual violence is a shared responsibility that requires the active involvement of all elements of society.ABSTRAKKekerasan seksual merupakan salah satu tindakan yang secara sengaja menghina, merendahkan, melecehkan, dan menyerang fisik, secara sengaja yang dapat merugikan seseorang. Sosialisasi ini bertujuan untuk menambah tingkat pengetahuan siswa terkait edukasi seks, serta bagaimana sikap remaja mencegah terjadinya pelecehan seksual. Pengabdian ini menggunakan metode PAR (Participatory Action Research) yakni sebuah metode dengan cara pendekatan terhadap siswa-siswi. Kegiatan ini dilaksanakan secara langsung dimulai dengan melakukan observasi, koordinasi, dan perizinan dengan kepala sekolah setempat terkait rencana kegiatan. Hal ini mencakup pengaturan mengenai ketersediaan tempat, waktu, dan peserta. Materi yang dipaparkan terkait wawasan mengenai kekerasan seksual, jenis-jenis kekerasan seksual, dampak kekerasan seksual serta hukum yang mengatur dan melindungi korban kekerasan seksual. Peranan sekolah dalam upaya pencegahan kekerasan seksual dan perlindungan HAM pada siswa belum dapat dilaksanakan maksimal, disebabkan belum tersedianya peraturan khusus dan satgas anti kekerasan yang dibentuk. Selain itu, upaya sekolah juga belum memiliki alur penanganan yang terstruktur. Sehingga perlu diberikan edukasi dan pengetahuan terkait hukum yang mengatur dan melindungi korban kekerasan seksual. Hasil kegiatan ini memperlihatkan adanya peningkatan pengetahuan, afektif serta pemahaman terkait kasus kekerasan seksual karena pencegahan kekerasan seksual merupakan tanggung jawab bersama yang memerlukan keterlibatan aktif dari seluruh elemen masyarakat.
