Abstract

Perumdam Tirto Jungporo merupakan Perusahan Daerah Air Minum yang ada di kota Jepara yang sangat diandalkan sebagian masyarakat dalam hal pendistribusian sumber air bersih. Pada saat ini perusahaan daerah kota Jepara tersebut memiliki jumlah pelanggan yang terus meningkat. Hal ini mengakibatkan penanganan kerusakan pada saluran air pelanggan juga ikut meningkat. Untuk pelayanan pengaduan kerusakan di perusahaan air ini masih menggunakan sistem manual, di mana pelanggan datang ke kantor untuk melakukan pengaduan. Sistem tersebut sangat tidak efektif dan efesien untuk pelanggan yang harus datang ke kantor yang pastinya akan menguras tenaga, waktu, dan juga biaya. Dari temuan tersebut, peneliti bermaksud membangun sistem informasi pengaduan pelanggan berbasis location based service untuk Perumdam Tirto Jungporo. Sistem ini dapat diakses menggunakan perangkat Android. Aplikasi ini telah berhasil diuji menggunakan metode black box dengan 135 responden dengan nilai 80% untuk aplikasi pelanggan, dan 80% untuk aplikasi petugas.

Abstract

Higher Education is a place for providing education that aims to produce quality human resources and is able to face increasingly fierce job competition. Therefore, from the recruitment process or the admission process, prospective new students must consider various procedures that aim to be able to direct prospective new students in determining the study program that will be taken by prospective new students. The things that have been broken in the admission process for new students include the scores of national exam results, report cards, school test scores and the admission test for new students, as well as the admission process of the achievement path and aiming for missions. From these things, performance must be improved is a supporting factor so that the process of transforming educational science to students can be carried out properly. The purpose of this study is to obtain classification in determining the study program of prospective new students by optimizing the Naïve Bayes and Decision Tree methods with an Unsupervised Discretization Approach, as an effort to improve the internal quality assurance system, especially the standards for the admission process for new students in determining study programs at the Harapan Polytechnic with Tegal. Where in the process of accepting new students, planning, implementing, evaluating, and monitoring have been carried out as a form of implementing the Internal Quality Assurance System (SPMI). In this study, the data used was data on the results of the admission of prospective new students from all study programs. These data include data on the administrative completeness of the requirements of prospective new students, as well as data on the value of the results of the new student admission test. The data used is data for 1 academic year 2019/2020. From this data, training and testing will be carried out using Rapidminer 9, a classification of lecturer teaching performance will be obtained.

Abstract

The problem of counseling guidance is one of the problems found in schools which is one thing that is difficult to predict. Accurate predictions are needed to support decision making for those who have policy in making decisions. One of the things that can be done to make predictions in providing guidance and counseling recommendations is to use the K-Nearest Neighbor method. Of the 388 students in the school, tests or experiments can be carried out using the K-Nearest Neighbor algorithm method. The results obtained from the experiment were 96.40% with 362 students who did not have to do counseling guidance, and 62 students who had to do counseling guidance. From the experimental results, it is hoped that the quality of the education system being carried out is expected to be further improved because it will affect the quality of the school.

Abstract

Field Work Practice is a learning activity that aims to introduce and expand students' skills in the real world of work. One of the PKL places that opens opportunities for students to carry out tasks is the Jepara Transportation Office. The Transportation Agency is a regional government organizing body in the field of transportation. But unfortunately, until now the Jepara Transportation Office does not have a system that can facilitate students and management staff to manage these PKL activities. This results in many documents that range lost and not well documented. The PKL information system with criteria assessment using a Likert scale is a solution in the PKL management process for the better. This application is web-based so that all data is managed and stored properly. This system has gone through the black box testing stage with the results of all features, flows, and programs that are normal and in accordance with what was planned at the beginning. In addition, the percentage of feasibility from the results of testing through a questionnaire to 12 respondents (users) of the Jepara Transportation Office E-PKL system received a score of 90.5% which means it is very feasible to use.

Abstract

Optimasi ongkos kirim (ongkir) dan rute pengiriman menjadi tantangan utama bagi usaha mikro, kecil, dan menengah (UMKM), terutama dalam meningkatkan efisiensi logistik. Toko Keripik Aldafa menghadapi permasalahan dalam menentukan ongkir secara akurat serta memilih rute pengiriman yang optimal karena masih menggunakan metode manual. Ketidakakuratan dalam estimasi biaya dan rute yang kurang efisien menyebabkan peningkatan waktu tempuh serta tingginya biaya operasional. Oleh karena itu, penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem berbasis web yang dapat membantu mengoptimalkan ongkir dan rute pengiriman dengan memanfaatkan Haversine Formula untuk perhitungan jarak geografis serta Algoritma Kruskal untuk menentukan jalur pengiriman terpendek. Metode yang digunakan dalam penelitian ini meliputi penerapan Haversine Formula untuk menghitung jarak berdasarkan koordinat lintang dan bujur, serta Algoritma Kruskal dalam membangun Minimum Spanning Tree (MST) guna menemukan jalur distribusi yang paling optimal. Pengujian dilakukan dengan membandingkan hasil perhitungan manual dan sistem berbasis web. Hasil penelitian menunjukkan bahwa sistem yang dikembangkan mampu meningkatkan akurasi estimasi ongkir dan mengoptimalkan rute pengiriman. Dibandingkan dengan metode manual, sistem ini berhasil mengurangi biaya logistik rata-rata sebesar 18,5% serta menghemat waktu tempuh hingga 22,3%. Selain itu, perbedaan hasil perhitungan manual (8.15 km) dan sistem (8.12 km) menunjukkan tingkat akurasi yang tinggi dengan selisih yang kecil. Dengan implementasi sistem ini, UMKM seperti Toko Keripik Aldafa dapat mengurangi ketidakefisienan dalam proses logistik dan meningkatkan daya saing di era digital. Penelitian ini juga membuka peluang pengembangan lebih lanjut, seperti penggunaan data real-time dan integrasi dengan sistem pemetaan lainnya untuk meningkatkan akurasi dan efisiensi distribusi barang.

Abstract

UMKM Gula Merah Sumber Madu di Kabupaten Kudus masih mengandalkan sistem penerangan konvensional yang menyebabkan pemborosan energi, keterbatasan kontrol operasional, serta potensi risiko keselamatan kerja akibat pencahayaan yang tidak optimal. Permasalahan ini mendorong perlunya penerapan teknologi yang sederhana, terjangkau, dan sesuai dengan karakteristik UMKM agroindustri tradisional. Kegiatan pengabdian kepada masyarakat ini memposisikan diri sebagai upaya implementatif penerapan teknologi Internet of Things (IoT) untuk meningkatkan efisiensi energi dan keselamatan kerja pada sektor UMKM. Metode yang digunakan adalah pengabdian berbasis penerapan teknologi tepat guna dengan pendekatan partisipatif, meliputi survei lokasi, perancangan sistem penerangan pintar berbasis IoT menggunakan perangkat SONOFF, instalasi sistem, pelatihan penggunaan aplikasi, serta evaluasi dan pendampingan. Hasil kegiatan menunjukkan bahwa sistem penerangan pintar berbasis IoT berfungsi dengan baik dan mampu menurunkan konsumsi energi listrik sektor penerangan hingga sekitar 17%. Selain itu, penerapan sistem ini meningkatkan keselamatan dan efektivitas kerja serta pemahaman mitra dalam memanfaatkan teknologi digital. Temuan ini menunjukkan bahwa teknologi IoT sederhana dapat diterapkan secara efektif dan berkelanjutan untuk mendukung efisiensi operasional dan transformasi digital UMKM agroindustri.
