se needs, an expert system based on the forward chaining method was developed that is able to diagnose damage automatically. This system was developed using the waterfall method, with systematic stages from analysis to implementation. The implementation results show that the system can identify the type of damage with an accuracy rate of 89% based on validation tests on 100 real troubleshooting cases. The evaluation metric uses a comparison between the results of the system diagnosis and the results of the technician's analysis. Although the system is able to increase service efficiency by up to 40% compared to conventional methods, several obstacles were found, such as the limited initial knowledge base that impacts the accuracy of the diagnosis and the difficulty of users in understanding the system interface. Therefore, further development is needed to expand the knowledge base and improve the user experience. This study aims to develop a forward chaining-based expert system to improve efficiency, accuracy, and speed of problem solving at CV.

Abstract:Abstract: Due to the successful conversion from LPG stoves to electric stoves, which are unsupported by the village’s electricity supply—averaging 450 watts—while government-provided stoves have a power rating of 900…
wer rating of 900 watts, making them unsuitable for use in Tomuanhollbung Village. To address this issue, the research team designed a stove that uses waste oil (35,000 kJ/kg) and incorporated embedded system technology, utilizing the French design research method. The research results indicated that by using a DC motor with specifications of 12VDC/3A, 3800 rpm, and a valve diameter of 9.7 x 9.5 x 3.3 cm, a power output of 36W was achieved, with a pressure of 288.7 Pa or 0.00289 bar and an angular velocity of 398.1 rad/s. When the burner stove was first ignited, the flame appeared yellow. With a voltage of 3.7VDC/3A, it produced a rotation of 3795 rpm, a yellow flame, a flame height of 8 cm from the stove, and a flame width diameter of approximately 18 cm. At a voltage of 3.7VDC, the pressure measured 0.000964 bar, with a flame temperature of 275°C (as measured by an infrared sensor). A voltage of 7.4VDC resulted in a pressure of 0.0192 bar and a flame temperature of 350°C, while a voltage of 11.8VDC produced a pressure of 0.0289 bar with a maximum flame temperature of 420°C. For fuel consumption over 10 minutes at 3.7VDC/3A, the flame height reached 7-10 cm, with a wind pressure of 0.000964 bar and a fuel consumption of 0.237 grams.

Rotational Churn, which is difficult to predict be- cause the reasons for stopping are unclear, is the main focus of this research. This research aims to group Rotational Churn customers using a Data-Centric AI approach. This approach emphasizes improving data quality through Confident Learning and Synthetic Data before being applied to the K-Means clustering algorithm. The data used in this research is customer churn data from one telecommunications company during 2023. The research results show that customer grouping using the K-Means algorithm can provide deep insight into the characteristics of customer churn. The application of Data-Centric AI is proven to be able to increase the accuracy of clustering models, which ultimately helps compa- nies optimize programs and services to minimize churn and retain customers.

Abstrak: Dalam era perkembangan teknologi yang sangat pesat saat ini, churn pelanggan menjadi tantangan serius, terutama dalam industri telekomunikasi yang sangat kompetitif. Churn mengacu pada pelanggan yang berhenti menggunakan layanan atau beralih ke penyedia lain, dan dapat dikategorikan menjadi tiga jenis: Churn Aktif, Churn Pasif, dan Churn Rotasional. Churn Rotasional, yang sulit diprediksi karena alasan penghentian layanan tidak jelas, menjadi fokus utama penelitian ini. Penelitian ini bertujuan untuk mengelompokkan pelanggan Churn Rotasional menggunakan pendekatan Data-Centric AI. Pendekatan ini menekankan pada peningkatan kualitas data melalui Confident Learning dan Synthetic Data sebelum diterapkan ke algoritma K-Means clustering. Data yang digunakan dalam penelitian ini adalah data churn pelanggan dari satu perusahaan telekomunikasi selama tahun 2023. Hasil penelitian menunjukkan bahwa pengelompokan pelanggan menggunakan algoritma K-Means dapat memberikan wawasan mendalam tentang karakteristik churn pelanggan. Penerapan Data-Centric AI terbukti mampu meningkatkan akurasi model klastering, yang pada akhirnya membantu perusahaan mengoptimalkan program dan layanan untuk meminimalkan churn serta mempertahankan pelanggan.

The absence of distribution transaction channels from upstream to downstream is one of the business problems at Toko 66. Therefore, a system such as Supply Chain Management is needed which can manage the flow of transactions from upstream to downstream and can also make it easier for owners to create sales reports. Based on the research results, it can be found that a system has been created that implements web-based Supply Chain Management to help owners, admins, suppliers and customers in carrying out transaction flows from upstream to downstream. The business process from upstream to downstream has also been running in accordance with the Supply Chain Management procedures that apply at the research object location so that it can provide information regarding the existence of sufficient product stock to ensure a good transaction flow from upstream to downstream.

Abstract:Abstract: Usability testing of online animal adoption systems is important because it is not only related to the comfort and safety of users, but also to the welfare of the adopted animals. So far, usability testing of the…
he animal adoption system on Eidos has not been carried out and there is a problem that there is confusion with the process flow in this animal adoption system. This usability testing uses the Heuristic Evaluation method and the System Usability Scale (SUS), which involves in-depth interviews to obtain results that are not only statistical assessments, but also deeper insights from the user's perspective. The results of the evaluation using Heuristic Evaluation obtained 59 problems, with an average severity rating of 3 or major, whose improvements have resulted in several draft design recommendations. The recommendation design has gone through final testing using the System Usability Scale (SUS) which managed to achieve a score of 78, or categorized as good, along with some minor critical feedback for system improvement. Therefore, users as a whole feel very satisfied in using the online adoption system from the results of the existing recommendation design. The implications of the resulting recommendation design have been tested for usability by three UI/UX design experts and users directly so that they can be used as a basis for developing a better online animal adoption system.

Abstrak: Pengujian usability sistem adopsi hewan secara online penting untuk diperhatikan karena tidak hanya berkaitan dengan kenyamanan dan keamanan penggunanya saja, tetapi juga meningkatkan kesejahteraan hewan yang diadopsi. Sejauh ini, pengujian usability dari sistem adopsi hewan pada Eidos masih belum dilakukan dan ditemukannya masalah bahwa adanya kebingungan dengan alur proses dalam sistem adopsi hewan ini. Pengujian usability ini menggunakan metode Heuristic Evaluation dan System Usability Scale (SUS), yang melibatkan in-depth interview untuk memperoleh hasil yang bukan hanya berupa penilaian statistik saja, melainkan juga wawasan yang lebih mendalam dari sudut pandang pengguna. Hasil evaluasi menggunakan Heuristic Evaluation mendapatkan 59 permasalahan, dengan rata-rata perhitungan severity rating sebesar tiga atau major, yang perbaikannya telah menghasilkan beberapa rancangan desain rekomendasi. Adapun desain rekomendasi tersebut telah melalui pengujian akhir menggunakan System Usability Scale (SUS) yang berhasil meraih skor sebesar 78, atau terkategori good, disertai beberapa umpan balik kritis yang bersifat minor untuk peningkatan sistem. Dengan demikian, pengguna secara keseluruhan merasa sangat puas dalam menggunakan sistem adopsi online dari hasil desain rekomendasi yang ada. Implikasi desain rekomendasi yang dihasilkan telah teruji kegunaannya oleh sebanyak tiga ahli UI/UX design dan pengguna secara langsung sehingga dapat digunakan sebagai landasan bagi pengembangan sistem adopsi hewan secara online yang lebih baik.
