Japanese is one of the most difficult languages to understand and read. Japanese writing that does not use the alphabet is the reason for the difficulty of the Japanese language to read. There are three types of Japanese, namely kanji, katakana, and hiragana. Hiragana letters are the most commonly used type of writing. In addition, hiragana has a cursive nature, so each person's writing will be different. Machine learning methods can be used to read Japanese letters by recognizing the image of the letters. The Japanese letters that are used in this study are hiragana vowels. This study focuses on conducting a comparative study of machine learning methods for the image classification of Japanese letters. The machine learning methods that were successfully compared are Naïve Bayes, Support Vector Machine, Decision Tree, Random Forest, and K-Nearest Neighbor. The results of the comparative study show that the K-Nearest Neighbor method is the best method for image classification of hiragana vowels. K-Nearest Neighbor gets an accuracy of 89.4% with a low error rate.

School accreditation activity is an activity undertaken to assess the quality level of each school. Implementation of accreditation under the auspices of the National Accreditation Board of School / Madrasah (BAN-S / M). At the district level task BAN-S / M aided by the Accreditation Implementation Unit (UPA). Accreditation assessment based on the National Education Standards (NES) which consists of content standards, standards of process, competency standards, standards of teachers and education personnel, standards of facilities and infrastructure, management standards, standards of financing, and standards of educational assessment In Indragiri Hilir in years 2007-2015 UPA has accredited 160 SMP. From the results of the accreditation of the period data showed that 54% of SMP in Indragiri Hilir has lower accreditation. One reason is the school not knowing how to repair priority decision determination standards of accreditation.Decision Support System (DSS) is needed to ableto determine prioritize improvements accreditation standards. AHP is a method to solve a complex problem into a hierarchy and generate the highest priority. Prioritization of repairs done on the accreditation criteria of sufficiency of funds, availability of resources, a period of improvement and weight rating BAN-S / M. DSS can help the school to do a repair priority setting standards for school accreditation.

Permasalahan yang sering terjadi dalam mengkonsumsi makanan adalah konsumsi gizi lebih atau kurang. Konsumsi buah dan sayur dapat menjadi sumber dari gizi untuk mencapai pola makan dengan gizi seimbang. Buah dan sayur merupakan sumber dari vitamin, mineral serta serat yang dapat membantu manusia dalam mengkonsumsi makanan secara seimbang. Kurangnya pengetahuan tentang buah dan sayur yang cocok untuk dikonsumsi serta kurangnya pengetahuan tentang kandungan gizi yang ada pada buah dan sayur menjadi faktor utama masih rendahnya konsumsi buah dan sayur. Tujuan dari penelitian ini adalah membangun sebuah sistem rekomendasi buah dan sayur yang dapat membantu konsumen dalam memilih buah dan sayur yang cocok berdasarkan umur dan preferensi konsumen. Penelitian ini menggunakan ontologi sebagai knowledge base dan metode profile matching sebagai metode untuk memberikan rekomendasi buah dan sayur. Penelitian ini berhasil mengimplementasikan sistem rekomendasi pendukung smart e-commerce dengan 30 data buah dan 30 data sayur menggunakan ontologi dan profile matching. E-commerce ini dapat memberikan rekomendasi buah dan sayur yang cocok berdasarkan pada umur konsumen. Penelitian ini juga menggunakan preferensi konsumen yang terdiri atas warna dan rasa buah dan sayur untuk menampilkan pilihan buah dan sayur yang disukai oleh konsumen. Kelemahan dari penelitian ini adalah perhitungan rekomendasi bersifat stastis, sehingga masih harus dilakukan kodifikasi ulang jika ada perubahan data buah dan data sayur yang dimasukkan berdasarkan kandungan gizinya.

Information technology has supported the development of quality school services throughout the world. However, there are still many schools that have not used it optimally, especially in Indonesia, for example at Prince Jayakarta Bekasi Middle School. As in general, schools only use Ms. Word and Ms. applications . Excel. This resulted in different assessment formats and errors when filling in grades into the report card format. The academic information system application developed in this study uses the PHP, HTML, and MySQL programming languages and is named SIAP, which means eighteen academic information systems. The purpose of making this application is so that students / parents of students can receive school assessment information in a precise, fast and accurate manner. Teachers can also use the facility to process student scores so that they are well integrated and summarized as data for the Principal to make policies. This application can be opened on any browser platform, making it easier for users to access it anywhere and anytime.

Salah satu bencana alam yang sering terjadi di Indonesia adalah Gempa Bumi. Berdasarkan BMKG, di Indonesia sering terjadi gempa bumi dengan magnitude 1 hingga 3 skala richter, peristiwa ini disebut dengan gempa micro. Dari tahun 2017 hingga 2018 telah terjadi 1624 data kejadian gempa bumi yang berkekuatan mulai dari 3 hingga 7 skala richter. Letak pusat gempa bumi yang jauh dari pemukiman juga menjadi faktor besarnya getaran gempa yang dirasakan. Identifikasi penyebaran gempa yang terjadi dapat dilakukan dengan metode Clustering dalam Data Mining. Pada penelitian ini metode clustering yang dilakukan adalah dengan menggunakan metode K-Medoids. Penelitian ini menggunakan 8 atribut pada data, data gempa yang ada di cluster menjadi 3 bagian, yang terdiri daerah rawan, sedang dan rendah. Hasil dari penelitian ini adalah terdapat 669 daerah yang berada pada tingkat rawan, 512 di tingkat sedang, dan 443 di tingkat jarang. Nilai rata-rata sillhouette yang diperoleh adalah 0.32.

Plantation communities in rural Indonesia, particularly in Pangalengan Village of Bandung Regency, predominantly rely on conventional sales channels such as direct transactions with middlemen, which result in uncompetitive pricing and limited market access. Although most farmers already own smartphones and use WhatsApp daily, low digital literacy prevents them from utilizing these tools for business development. This community service activity aimed to enhance the digital business capacity of village plantation farmers through hands-on training on WhatsApp Business and online marketplaces. The implementation method comprised four stages: needs analysis, socialization (Day 1), practical training (Day 2), and evaluation. Fifty participants from Pangalengan Village joined the two-day training program. Results indicate substantial improvement in participants’ digital literacy: 92% successfully created active WhatsApp Business accounts with product catalogs, and 76% uploaded at least one product to Tokopedia or Shopee. The average pre-test score rose from 34 to 81 (out of 100) on the post-test. The activity successfully shifted participants’ marketing approach from traditional to digital, expanding market access and reducing dependence on middlemen.

The development of Air Conditioner technology to stabilize the temperature and humidity of the air in a room has affected human life activities. This research designed an automatic control system for air conditioning using the Fuzzy Mamdani method, because it is known that air conditioners have the largest cost burden compared to other electronic devices. Then, this research designed a control system consisting of a DHT22 Sensor as an input to detect the room temperature controlled by the ESP32. Furthermore, the results of data collection are analyzed using the Fuzzy Mamdani method so that the defuzzification output instructs the relay to take action, namely switching off to adjust the temperature degree and display data to the IoT platform, ThingSpeak. The results of this research show that the DHT22 sensor test was successfully calibrated with a hygrometer comparator with an error value of 0.4%. Then, the prototype design based on fuzzy rules has been successfully implemented with an error value of 9.2% from the manual comparison so that it is concluded that the deviation difference is still recommended. This indicates that the system effectively maintains desired environmental conditions while improving energy efficiency by reducing unnecessary AC usage. The results confirm the feasibility of implementing IoT-based fuzzy control systems for practical energy-saving applications.
