Abstract

Given the large number of fatalities and the amount of economic and social losses caused by road accidents, it is necessary to build a road safety culture early on in Indonesia. Various programs and socialization efforts have been carried out to reduce the high number of accidents. One of the socialization steps is the concept of introducing SMS gateway surveillance for parents to be able to supervise the use of vehicles by young teenagers. The concept of notification in the form of an SMS gateway is more specifically devoted to motorbike riders for teenagers who are only able to drive on public roads, bearing in mind young teenagers are often reckless then it is the biggest contributor to accidents in Indonesia. This research is focused on the problem of means of use and supervision in driving, especially for parental supervision of young teenagers. Using this system will reduce road accidents, because young teenagers will be monitored by this system and notified their parents to take further action against vehicle users. This form of system works if the driver crosses the normal speed of driving, the system will automatically send sms to the parents of the children who are driving, the parents' supervision of the child in driving increases so that the level of traffic accidents will decrease, and parents can find out where their child is.

Abstract

This Community Service aims to socialize the introduction of array formulas in Excel to SMA 1 Gunung Talang Solok students. Array formulas are a very useful feature in data processing in Excel, but are often not widely known by high school students. The method used in this research is a socialization method which involves presentations, demonstrations, and direct practice using array formulas in Excel. Socialization was carried out in the form of training involving SMA 1 Gunung Talang Solok students. The research results showed that the socialization of the introduction of array formulas in Excel had a positive impact on students at SMA 1 Gunung Talang Solok. After following the socialization, students were able to understand and apply array formulas in data processing in Excel. They are able to create array formulas that are more efficient and accurate in completing tasks that involve data processing

Abstract

Farmers still do not really understand how to diagnose problems in plants, one example is strawberry farmers. This is proven by several farmers and strawberry plant cultivators, not all of whom can understand the disease where there are various types of diseases that can attack strawberry plants with almost the same symptoms , and if a farmer or cultivator is wrong in handling the type of strawberry plant disease, it is not impossible that it will cause the strawberry plant to die. Strawberry farmers need a tool to diagnose strawberry plant diseases so that they can find out the condition of the strawberry plants. Therefore, an expert system was created to diagnose diseases in strawberry plants and find solutions to deal with the damage that occurs. The system built for diagnosing diseases in strawberry plants uses the Forward Chaining method. Forward chaining is a forward tracking that starts from a set of facts by looking for rules that match the existing hypothesis towards a conclusion. In its implementation, this system has met these objectives by using a database and rule base. The system draws conclusions based on existing facts using the forward chaining method, the search starts from the facts from which new conclusions are obtained, the existing rules are traced one by one until the search is stopped because the last condition has been met.

Abstract

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.

Abstract

SMA N 1 Batang Anai merupakan salah satu sekolah yang sudah menerapkan teknologi dalam bidang pendidikan dengan sebaik-baiknya. Sekolah tersebut membangun sistem informasi yang diberi nama BeeSmart, yang merupakan sistem informasi pertama yang digunakan di sekolah tersebut untuk siswa dan guru dalam melaksanakan ulangan harian secara terkomputerisasi. BeeSmart tersebut diharapkan dapat menjadi pedoman untuk sekolah lain yang belum menerapkan teknologi dalam pembelajaran, oleh karena itu sebagai pelopor sistem informasi ulangan harian BeeSmart tentu harus memenuhi standar kualitas sistem yang baik dan jauh dari kekurangan. Dengan menggunakan metode yang ada, maka kualitas dari sistem informasi ulangan harian ini dapat diukur dan diperbaiki lebih baik.

Abstract

Loyalitas konsumen adalah elemen penting untuk memastikan kelangsungan hidup bisnis dalam pasar ritel yang sangat kompetitif. Penelitian ini bertujuan untuk meningkatkan loyalitas konsumen dengan menerapkan sistem Customer Relationship Management (CRM) berbasis web yang terintegrasi dengan metode pengambilan keputusan multi-kriteria, yaitu Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Penelitian dilakukan di Friiday Store, sebuah toko yang menjual aneka aksesoris, dengan pendekatan campuran yang mencakup pengembangan sistem, analisis kuantitatif, dan uji pengguna. Metode TOPSIS digunakan untuk menilai alternatif produk berdasarkan kriteria utama seperti harga, desain, dan ulasan pelanggan, sehingga dapat menghasilkan peringkat dan rekomendasi produk berdasarkan data. Sistem CRM mempermudah interaksi dengan pelanggan, pengelolaan transaksi, serta menawarkan layanan yang disesuaikan melalui fitur katalog daring, riwayat pembelian, dan obrolan langsung. Temuan penelitian mengindikasikan bahwa penggabungan TOPSIS dalam CRM secara signifikan meningkatkan kepuasan serta loyalitas pelanggan berkat rekomendasi produk yang lebih relevan dan peningkatan dalam layanan responsif. Sistem ini juga membantu dalam pengambilan keputusan bisnis melalui wawasan yang dapat diterapkan dari analisis preferensi pelanggan. Penelitian ini menyimpulkan bahwa gabungan antara CRM dan alat pengambilan keputusan multi-kriteria seperti TOPSIS memberikan pendekatan strategis untuk menjalin hubungan yang tahan lama dengan pelanggan serta meningkatkan tingkat retensi dalam usaha ritel kecil dan menengah. Kata kunci: CRM, TOPSIS, Loyalitas, Kepuasan
