Abstract

With the advancement of information technology, the application of machine learning in the property industry, particularly for house price prediction, has become increasingly important. Technology plays a crucial role in speeding up and enhancing the accuracy of property buying and selling processes. Therefore, the role of machine learning technology can be utilized to meet the need for improving the accuracy of house price predictions in major cities of developing countries, such as Bandung. This research aims to analyze the effectiveness of the Artificial Neural Network and Random Forest algorithms in predicting house prices in Bandung. The data used includes house sales data in Bandung, covering land area, building area, number of bedrooms, number of bathrooms, number of parking spaces, and the subdistrict location. The analysis of the algorithms is conducted by comparing the performance testing results of both algorithms using performance metrics for regression models such as Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and R-Square (R2). Additionally, this research analyzes which data ratio among the training, validation, and test data yields the best results. The research findings indicate that the model with a data ratio of 60:20:20 produces the best performance for both algorithms. The Random Forest algorithm demonstrates superior performance with results of MAE: 0.0470; MSE: 0.0079; RMSE: 0.0888; and R2: 0.7085.

Abstract

The younger generation is particularly susceptible to the dangers of drug abuse due to the potential long-term consequences associated with narcotics use. Consequently, they often find themselves in the crosshairs of drug trafficking syndicates seeking financial gain. In response to this issue, the government, working in conjunction with the National Narcotics Agency (BNN), has introduced the Program for Prevention, Eradication, Abuse, and Illicit Trafficking of Drug Precursors (P4GNPN) as a strategic measure to combat drug trafficking. Aligned with the broader anti-narcotics movement in Indonesia, our implementation team has launched a training program aimed at harnessing the power of interactive systems to serve as an educational tool on drug-related matters. The primary recipients of this program are teachers who are active members of the Indonesian Teachers Association (PGRI) in Pangandaran Regency. The fundamental objective of employing this interactive system is to empower users with the capability to access drug information and counseling interactively and on a personal basis, regardless of their location or the time of day. The participants have been thoroughly trained in the proper use and effective utilization of this interactive system. According to the feedback obtained through the evaluation process, participants have expressed a clear understanding of the material, and the training has significantly boosted their motivation to carry out anti-drug movements. With the introduction of this community service initiative, we aspire to lend support to the government's and society's collective efforts in addressing the pressing issue of drug abuse among the younger generation.

Abstract

Desa Kampoeng Rajoet Binong Jati, sebagai salah satu desa wisata di wilayah Timur Kota Bandung, dengan bangga menonjolkan potensi dan keunikan yang menjadi daya tarik bagi wisatawan. Terkenal karena industri rajut yang dimulai pada tahun 1960-an, desa ini telah mengalami pertumbuhan pesat, dengan 400 pengrajin rajut yang memproduksi sekitar 4.500 lusin pakaian rajut per bulan dan berhasil mengekspor produknya ke berbagai negara. Namun, dengan masuknya era revolusi industri 4.0, desa ini dihadapkan pada tantangan teknologi dan informasi. Saat ini, proses pembuatan laporan dan pencatatan stok masih bersifat manual, menyebabkan ketidakefisienan dan tingkat kesalahan yang signifikan, mengakibatkan kerugian materi. Oleh karena itu, tim Pengabdian kepada Masyarakat (PkM) telah mengembangkan aplikasi pencatatan inventori barang berbasis website yang diberi nama SiRajoet untuk membantu desa meningkatkan efisiensi, efektivitas, dan optimalisasi bisnisnya. Selain pembuatan aplikasi, kegiatan sosialisasi dan pelatihan diadakan untuk memberikan informasi dan keterampilan kepada masyarakat Kampoeng Rajoet. Meski sistem ini berhasil mengatasi masalah pencatatan stok barang dan laporan, namun SiRajoet masih memiliki beberapa kekurangan yang akan menjadi dasar untuk kegiatan PkM di Kampoeng Rajoet di masa mendatang.
