Gingivitis is a disease in the form of abnormalities in the gingiva that can cause bleeding accompanied by swelling, redness, exudate, changes in normal contours which are sometimes considered normal by some patients even though it is considered serious by the Health Department. This study aims to educate the public in understanding the importance of knowing the condition of the body, especially the teeth that are most vulnerable to experience by the community. The lack of time required for consultation with experts resulted in this disease being left unattended. So it is necessary to develop IT-based consulting in the form of an expert system. The system is built using the certainty factor method. Certainty factor works by reading all the data submitted by the expert and gives the result in the form of the percentage of confidence the patient has gingivitis. Experts used in this system are dentists / dental specialists. The data were obtained from direct experts and the results of the consultations obtained new knowledge in the form of the percentage of the patient's confidence level with gingivitis. Data collection was obtained from Acute Gingivitis, Sub-Acute Gingivitis, Recurrent Gingivitis and Chronic Gingivitis as well as symptoms and solutions obtained from experts. This study contributes to a new service for patients who experience dental disease (gingivitis) without having to come directly to an appointed specialist. The level of accuracy of this system is quite helpful because the data source comes from direct experts so that the solution obtained can be an initial reference for patients before further treatment is carried out. The results of the study were in the form of softcopy and hardcopy that could be used as needed, based on the test data given to the patient, a 95% confidence level was obtained for the system trial results based on the patient's condition at that time. So that the results of the consultation are obtained in the form of information about the disease and the desired solution.

Keberhasilan pengembangan sektor pariwisata tidak hanya bergantung pada daya tarik wisata semata. Terdapat banyak faktor dalam penghambat perkembangan sektor tersebut. Salah satu faktor tersebut adalah kurangnya perkembangan dalam pola periklanan dan sistem pengelolaan informasi pariwisata. Sebagai akibatnya, sasaran pariwisata tidak terdefinisi dengan baik, dan wisatawan mungkin tidak memilih destinasi tersebut. Bukitinggi sebagai salah satu destinasi wisata yang terdapat di Sumatera Barat juga tidak lepas dari permasalahan tersebut. Kurang tersedianya informasi lengkap tentang potensi pariwisata di Kota Bukittinggi membuat wisatawan mengandalkan sumber-sumber seperti media sosial, internet, dan sumber lainnya untuk mendapatkan informasi. Namun, informasi yang ada belum mencakup seluruh aspek pariwisata, sehingga menyebabkan ketidakpastian bagi calon wisatawan. Untuk mengatasi permasalahan tersebut, dihadirkan sebuah sistem respons obrolan otomatis atau disebut dengan Chatbot. Teknologi Chatbot merupakan salah satu bentuk sistem Natural Language Processing (NLP) dalam kecerdasan buatan. Chatbot berperan sebagai agen percakapan yang dapat berfungsi sebagai meja bantuan. Dalam konteks ini, helpdesk menjadi elemen penting yang menangani berbagai keluhan dari berbagai pihak dengan menyediakan informasi dan solusi. Dalam penelitian ini, dikembangkan sistem Chatbot menggunakan algoritma Naive Bayes untuk menjawab pertanyaan umum (FAQ) mengenai informasi pariwisata di Kota Bukittinggi.

Copra is dried coconut meat that is used to produce coconut oil. According to the Central Statistics Agency (BPS), Indonesia's copra production in 2020 reached 2.3 million tonnes. This is one form of the process of improving the economy of people living on the coast. This research was conducted to educate farmers in determining the level of maturity of the copra meat produced. This research was conducted using an extraction method that involves colour extraction and texture extraction. the method is used to provide convenience in seeing the level of maturity of the two characteristics of copra obtained in the field, namely texture and colour. The process obtained in the training with one of the images used as a test image in colour extraction produces area, perimeter, metric and eccentricity values in label 3 with values of 651.00, 184.69, 0.24 and 0.89. while in the feature extraction method the results are obtained with an average intensity value of 243.31, standard deviation of intensity 39.76 and entropy value of the tested image 4.57. The method is able to perform a detection process so that it can determine the level of maturity of copra seen from the existing types of copra such as asalan copra, regular copra, black copra and wet copra, each of which provides different functions in the copra processing stage. The process will be carried out using KNN which is seen from all test data and training data stored after the detection process. The results of the process carried out using digital images involving the extraction method for detection and KNN for classification are able to provide the right value. This is evidenced by the better accuracy value of 98%.

Herpes zoster merupakan infeksi virus yang menyerang kulit dan sistem saraf perifer, ditandai dengan kemunculan lesi kulit berwarna kemerahan berbentuk ruam atau lenting. Deteksi dini terhadap lesi herpes penting untuk mendukung diagnosis klinis dan mencegah komplikasi lanjut. Penelitian ini bertujuan untuk mengembangkan sistem deteksi otomatis lesi herpes berbasis segmentasi citra digital. Metode yang digunakan mencakup akuisisi citra pasien, pra-pemrosesan (konversi grayscale dan filtering Gaussian), serta segmentasi area terinfeksi menggunakan metode thresholding Otsu dan deteksi tepi Canny. Hasil segmentasi divisualisasikan dengan pemberian bounding box dan pelabelan numerik terhadap setiap area lesi. Pengujian dilakukan pada citra klinis penderita herpes dengan lima area lesi yang berhasil terdeteksi secara otomatis, masing-masing ditandai sebagai Area 1 hingga Area 5. Luas area tersegmentasi dihitung dalam satuan piksel dan diperoleh hasil sebagai berikut: Area 1 = 2.143 piksel, Area 2 = 1.912 piksel, Area 3 = 3.472 piksel, Area 4 = 1.165 piksel, dan Area 5 = 3.805 piksel. Evaluasi akurasi segmentasi dilakukan dengan perbandingan terhadap ground truth berbasis anotasi manual oleh ahli dermatologi. Hasil evaluasi menunjukkan tingkat akurasi sebesar 99,67%, sensitivitas 91,3%, dan spesifisitas 99,2%. Penelitian ini menunjukkan bahwa metode segmentasi citra digital efektif dalam mengidentifikasi lesi herpes pada kulit dengan tingkat akurasi yang tinggi.

Low levels of product literacy among consumers often cause a mismatch between the specifications of the purchased mobile phone and their actual needs. This problem is common, especially in stores that provide a wide selection of products with technical information that is poorly understood by prospective buyers. Lack of understanding of features such as processor type, camera quality, RAM capacity, and internal memory makes the purchasing process less than optimal. This study aims to improve consumer literacy by developing a mobile phone purchase recommendation system based on the C4.5 algorithm. The method used is a data mining approach with stages of collecting historical consumer purchase data, preprocessing data to eliminate noise, labeling purchase decisions, forming a decision tree model using the C4.5 algorithm, and evaluating model performance using a confusion matrix. The dataset used includes 19 types of mobile phones from a local store with attributes such as processor, main camera, front camera, RAM, internal memory, and price. The method used in this study uses the C4.5 algorithm. The results of the study show that the C4.5 algorithm is able to classify data with satisfactory accuracy and produce a relevant recommendation system. In addition to providing product suggestions, this system also includes a logical explanation of each decision taken, thereby increasing consumer understanding. Thus, this system not only helps the decision-making process, but also acts as an educational medium in increasing consumer literacy regarding mobile phone product specifications that suit their needs and budget.
