Line Maze Solving algorithm is an algorithm for line follower robot that is used on maze with right angle intersections. Previous work has improved the algorithm so that it can be used for the maze with curved and zig-zag intersections. The improvement was done because the algorithm only recognizes right angle intersections. This research presented the analysis process of the improvement of the algorithm in details, hence the difference between Line Maze Solving algorithm before and after the improvement can be seen clearly.

Getah karet merupakan salah satu hasil perkebunan yang cukup tinggi di Indonesia, oleh karena itu pengembangan kualitas getah karet merupakan suatu hal yang sangat penting. Karena mutu yang baik akan menghasilkan produk yang baik juga. Biasanya kualitasgetah karet ditentukan oleh Kadar Karet Kering (KKK) yang tinggi dengan kandungan air yang rendah. kadar karet kering juga dapat dijadikan tolak ukur untuk menilai kualitas pohon karet terbaik. Pada penelitian ini telah mendapatkan hasil perangkingan yang didapatkan dari nilai akhir masing masing metode. Peringkat pertama pada metode MOORA dengan niali 2,603 pada sensitivitasi 3 dan yang terendah pada metode SMARTER dengan nilai 0,084 pada sensitivitas pertama. Dan pada sensitivitas kedua, semua metode memiliki nilai yang sama yaitu 0,2. Maka dapat disimpulkan MOORA merupakan metode terbaik dari 2 metode lainnya.

The online marketplace can make it easier for fish breeding businesses to promote products and make it easier for consumers to get information about the products owned by the breeder. Limitations of product marketing are an obstacle for a fish breeder in increasing sales, moreover, manual reporting harms fish breeder by recording sales reports, so that sales and inventory reports are obstructed.The purpose of this research is to create an e-commerce-based online sales website that can be accessed online. The method used by the researcher in this research is the waterfall method. This method is used by researchers to build a software sistem by having a software flow starting with sistems engineering, analysis, design, coding, testing, and maintenance. The sistem design uses Unified Modeling Language, PHP programming language, and MySQL database.This research is conducted on a web-based online sales application that provides real-time inventory information, sales reports, inventory reports, fish seed production annual report and sellers can promote the products they sell by fish farmers in kampar district. Because of the process of reporting and checking inventory, the information can be carried out correctly and the seller's marketing reach can be wider so that it can increase income for fish breeding farmers in Riau Province especially in the district of Kampar.

Stock price prediction using machine learning is a rapidly growing area of research. However, the large number of features that can be used can complicate the learning process. The feature selection method that can be used to overcome this problem is recursive feature elimination. Standard recursive feature elimination carries the risk of producing inaccurate algorithms because the top-ranked features are not necessarily the most important features. This research proposes a feature selection method that combines important features and nonparametric correlation in recursive feature elimination for stock price prediction. The data features used are technical indicators and stock price history. The recursive feature elimination method is modified with important features and nonparametric correlation features. The strategy for combining important features and non-parametric features is average weight, 25:75% weight, 75:25% weight, maximum weight, and minimum weight. The performance evaluation results show that the proposed feature selection method succeeded in obtaining small error values. The proposed method for predicting PT Bank Rakyat Indonesia Tbk (BBRI) stock prices obtains mean squared error, root mean square error, mean absolute error, and mean absolute percentage error evaluation values of 0.0000336, 0.00577, 0.00459, and 1.78%, respectively. This shows that recursive feature elimination with feature selection that combines important features and non-parametric correlation works better than the original recursive feature elimination at predicting stock prices.

Penelitian ini membandingkan algoritma shortest path klasik, khususnya Dijkstra, dengan sistem penentuan rute berbasis waktu nyata seperti Google Maps dalam konteks efisiensi perjalanan. Simulasi manual dilakukan menggunakan graf berbobot statis, sementara studi kasus di Kota Pekanbaru digunakan untuk mengamati rekomendasi rute Google Maps pada dua waktu berbeda. Hasil simulasi menunjukkan bahwa algoritma Dijkstra menghasilkan rute optimal tetap (contoh: A → C → D → E dengan total waktu 5 menit pada kondisi normal), namun tidak dapat beradaptasi ketika terjadi perubahan kondisi lalu lintas. Sebaliknya, hasil observasi Google Maps menunjukkan adanya variasi rute: pada malam hari rute tercepat ditempuh dalam ±19 menit dengan jarak ±11,2 km, sementara pada siang hari rute berbeda dipilih dengan waktu tempuh lebih lama ±26 menit meskipun jaraknya hampir sama (±10,9 km). Perbedaan ini menegaskan bahwa Google Maps memperbarui bobot graf internalnya secara dinamis untuk menyesuaikan dengan kondisi lalu lintas. Temuan ini menyoroti keterbatasan algoritma konvensional di lingkungan perkotaan dinamis, sekaligus memperkuat keunggulan sistem navigasi berbasis data. Dengan demikian, penelitian ini menyimpulkan bahwa algoritma shortest path klasik relevan untuk tujuan edukatif dan simulatif, tetapi sistem navigasi berbasis data waktu nyata lebih efektif diterapkan dalam transportasi perkotaan yang kompleks.

The application of Information Technology is one of the efforts to implement the Tri Dharma of Higher Education, namely community service by voluntarily creating an Information System for the Laboy Jaya Village Farmers Group. Lack of understanding of information technology among the public has resulted in the process of collecting, storing and analyzing data being inefficient. In addition, existing agricultural data remains fragmented across various sources and formats, making integration of critical information difficult. Limited access to timely information, such as weather forecasts and market prices, also results in suboptimal agricultural decisions. Additionally, low technological skills among employees create resistance to change and reduce work productivity. To overcome these problems, the solutions offered include intensive and ongoing training on the use of agricultural information systems for the community, development of integrated information systems that integrate various data sources, increasing the accessibility of agricultural information via mobile or web applications, as well as technology skills development programs. By implementing these solutions, it is hoped that the efficiency and effectiveness of agricultural data management will increase, supporting the productivity and welfare of farmers in Kampar Regency.

The lack of physical activity in society has become one of the main factors contributing to the increased risk of non-communicable diseases. GPS-based technology has rapidly developed and can be utilized to enhance motivation for exercising. This community service program aims to educate and assist the public in using GPS-based exercise tracking applications to increase their physical activity. The methods used include socialization, training, monitoring of application usage, and evaluation of its effectiveness. The results indicate that the application helps raise awareness and motivation for exercising, as evidenced by the increased frequency and duration of physical activity. Thus, the use of GPS-based exercise tracking applications can be an innovative solution for promoting a healthier lifestyle in society.

Motorcycles are the most dominant means of transportation today, especially for the people of Bangkinang, and some people even prefer to look for used motorbikes because the prices are more affordable. Before someone starts deciding to get the desired means of transportation, they usually start by making several considerations. To find a used motorbike with certain criteria is a job that is quite difficult and troublesome and takes a long time, in order to get a used motorbike that really meets expectations, someone is willing to search every shop, this of course requires quite a lot of time and money. Therefore, this thesis builds a Web- based Information System for Used Motorcycle Dealers in Bangkinang Kota District so that it can help people find information on selling used motorbikes according to their needs. In testing the system using the blackbox testing method, all the features in this system run 100% indicating that the system is free of bugs.
