Abstract

This study aims to classify drinking water potability based on physical and chemical parameters using the K-Nearest Neighbors (KNN) algorithm. The dataset, sourced from the Kaggle platform, contains 100,000 water samples with nine key attributes, including pH, hardness, total dissolved solids (TDS), sulfate, chloramines, conductivity, organic carbon, trihalomethanes, and turbidity. The target label is potability, indicating whether the water is safe (1) or unsafe (0) for consumption. The preprocessing steps included normalization and splitting the data into training and testing sets. The KNN model was trained by experimenting with various K values to achieve optimal performance. Evaluation using a confusion matrix showed that the model achieved an accuracy of 78%. For the potable class, the model reached a precision of 72%, recall of 91%, and F1-score of 81%. For the non-potable class, it achieved a precision of 88%, recall of 65%, and F1-score of 75%. Although the model tends to misclassify unsafe water as safe, overall performance is promising. These findings suggest that the KNN algorithm can serve as an effective classification approach and has potential for application in automated water quality monitoring systems.

Abstract

Syifa Hidroponik, sebuah Usaha Mikro, Kecil, dan Menengah (UMKM) yang bergerak dalam budidaya hidroponik, didirikan oleh Ir. Suardi Raden pada tahun 2014, menghadapi tantangan dalam manajemen produksi dan pemasaran. Pendekatan Pengabdian kepada Masyarakat telah diambil untuk mengatasi masalah-masalah ini. Di bidang produksi, solusi telah diterapkan untuk meningkatkan pengelolaan kualitas air, pemberian nutrisi yang tepat, perlindungan tanaman dari kontaminasi dan hama, serta pengendalian suhu dan kelembapan. Hasilnya, kualitas air telah ditingkatkan, pemahaman tentang nutrisi tanaman meningkat, perlindungan tanaman diperkuat, dan suhu serta kelembapan terkontrol secara efisien. Di bidang pemasaran, strategi pemasaran konten yang lebih tepat telah diterapkan dengan mengidentifikasi target pasar yang spesifik, memberikan pelatihan, dan memanfaatkan berbagai platform media sosial. Hasilnya adalah peningkatan lalu lintas media sosial, pengunjung situs web, dan penggunaan iklan digital. Implementasi ini telah memberikan manfaat signifikan bagi Syifa Hidroponik dengan meningkatkan penjualan dan daya saing di pasar. Secara keseluruhan, pendekatan Pengabdian kepada Masyarakat telah membantu Syifa Hidroponik mengatasi masalah produksi dan meningkatkan strategi pemasaran, dengan dampak positif pada kualitas produksi dan pertumbuhan bisnis.

Abstract

Ujungmanik Village has a eucalyptus oil distillery with essential oil products produced of 100 kg per year. The problem is that the waste from the eucalyptus oil distillation, in the form of twigs and leaves from the eucalyptus oil distillation, accumulates and reduces the production area. The purpose of this study was to design a eucalyptus waste compost fertilizer packaging machine with the addition of a load cell sensor. The method used in making this compost fertilizer packaging machine is a PLC control system for the packaging section and ESP8266 is used to control the load cell sensor for weighing during the packaging process. The test results show that the eucalyptus oil distillation waste compost fertilizer packaging machine based on the PLC control system is capable of packaging 1000-gram organic fertilizer by the load cell sensor and is capable of packaging 10 plastic bags. Based on the monitoring results through the Blynk application, the packaging has an average value of 994.1 grams and an error percentage of 2.1%

Abstract

This community engagement project aimed to address operational challenges faced by Micro, Small, and Medium Enterprises (MSMEs) through an integrated Point of Sales (POS) system. A case study at Akane Beauty Studio and Salon used a User-Centered Design (UCD) and Rapid Application Development (RAD) approach, managed under the PMBOK framework. The implementation yielded a significant impact on operational efficiency, notably reducing transaction time from over one minute to under one minute. A comparison of the workflow also showed improvement, with a manual process that previously took four minutes now being completed in two minutes. User Acceptance Testing (UAT) confirmed the system was fully functional and easy to use. This project demonstrates that a user-centric digital solution can tangibly improve the efficiency, data accuracy, and business sustainability of MSMEs.
