Abstract

Pertemuan 5 Menit (P5M) is a routine activity that is always carried out by instructor in Politeknik Manufaktur Astra (Polman Astra) to students in each Unit Pelaksana Teknis (UPT) before or after lectures begin. Students who do not follow or violate the rules at the time of P5M will get a penalty in the form of minus hours. Minus hours are penalties given to students. Data minus hours of P5M are recorded using a form that is recapitulated one by one for every week and inputted into academic information system  Polman Astra. The input time for minus P5M clock data is 565 minutes. Therefore we need an information system that can help overcome or automate it. In this research an analysis and design will be carried out using the System Development Life Cycle (SDLC) stages with extreme programming methodology which will reduce the recapitulation time from 565 to 280 minutes.

Abstract

P5M is a readiness inspection activity such as the attributes and attendance of students before practicing. Students whose attributes are incomplete will be recorded in P5M sheet. Each attribute has a violation point or hour minus. P5M data, will recapitulate the number of hours minus. Constraints that occur in the Astra Manufacturing Polytechnic, namely the filling process of P5M sheets is still manual. This causes the time required to recapitulate minus hours to be long, which is on average 5 minutes. This causes the process of renewing the number of hours minus students and the process of paying hours minus being hampered. To overcome this, an Android-based P5M information system was made. This information system was developed using the Extreme Programming methodology and the MySQL database. With the P5M information system, it can eliminate the process of recapitulation of minus hours and reduce paper usage.

Abstract

Children’s health and development are critical for maintaining national productivity and independence, with stunting being a major concern. Stunting, a form of malnutrition, impairs growth and development, affecting millions of people globally, including a significant number in Indonesia. This study addresses the challenge of stunting by developing a predictive model using machine learning techniques to forecast stunting risks based on public health data. The literature review section discusses the factors that influence stunting, and these factors are used as features to build a stunting prediction model. Then the features were used to build a model with three machine learning algorithms Extreme Gradient Boosting (XGBoost), Random Forest, and K-Nearest Neighbor (KNN) to build and evaluate models that predict stunting. The models were trained and assessed using public datasets and the most effective algorithm was integrated into a mobile application for practical use. The results indicate that the XGBoost model outperforms the other models with an accuracy of 85%, making it the optimal choice for implementation in a mobile application. The next-best model is selected to be implemented through a mobile application so that users can directly use the model that has been built. This application aims to enhance early detection and intervention efforts for stunting, potentially improving child health outcomes and contributing to long-term productivity by building predictive models and implementing the models into a mobile application. This study contributes to the implementation of models built using public data for application in mobile applications.

Abstract

Mahasiswa tingkat akhir sering mengalami kesulitan dalam menentukan judul dan tujuan Tugas Akhir yang sesuai dengan minat, kompetensi, dan bidang keilmuan. Permasalahan ini didukung oleh hasil survei terhadap 30 mahasiswa program studi teknologi informasi melalui kuesioner daring, yang menunjukkan bahwa sebagian besar responden mengalami kendala dalam pemilihan topik Tugas Akhir akibat keterbatasan referensi yang relevan dan terarah. Meskipun literatur ilmiah tersedia dalam jumlah besar, belum terdapat sistem yang secara khusus membantu mahasiswa dalam merekomendasikan judul Tugas Akhir secara personal dan berbasis data. Penelitian ini mengembangkan model sistem rekomendasi judul Tugas Akhir menggunakan pendekatan content-based filtering berbasis pembelajaran mesin. Tahapan pengembangan meliputi pra-pemrosesan data berupa ekstraksi fitur teks dan pemodelan profil mahasiswa, yang selanjutnya dihitung tingkat kesamaannya menggunakan metode cosine similarity. Evaluasi model dilakukan menggunakan metrik Precision at K dengan nilai K = 10 dan menghasilkan tingkat presisi sebesar 99% pada data uji. Kontribusi penelitian ini terletak pada perancangan model rekomendasi yang mengintegrasikan profil mahasiswa dan konten referensi ilmiah secara efektif. Model yang dikembangkan diimplementasikan dalam prototipe berbasis web menggunakan framework Flask sebagai alat bantu penentuan judul Tugas Akhir.

Abstract

Proses deployment perangkat lunak .NET di PT XYZ saat ini menghadapi hambatan operasional berupa prosedur manual yang memicu rework akibat ketidakkonsistenan data administrasi, sehingga menyebabkan latensi eksekusi yang menghambat delivery time. Penelitian ini bertujuan untuk merancang modul otomasi yang mampu melakukan validasi dokumen secara mandiri, mengeksekusi prosedur backup, dan mendistribusikan file melalui path network secara presisi. Metodologi yang digunakan adalah Software Development Life Cycle (SDLC) model Waterfall dengan pendekatan Robotic Process Automation (RPA) berbasis Microsoft Power Automate. Hasil implementasi menunjukkan peningkatan performa yang signifikan, di mana durasi eksekusi teknis berhasil dipangkas dari rata-rata 20 menit menjadi hanya 73 detik, yang merepresentasikan peningkatan efisiensi waktu sebesar 93,9%. Selain itu, solusi ini berhasil mengeliminasi latensi koordinasi manual hingga dua hari kerja. Transformasi digital ini juga meningkatkan tingkat transparansi dokumentasi (traceability) secara drastis dari 0% menjadi 100% melalui mekanisme logging otomatis, sehingga memperkuat akuntabilitas dan tata kelola operasional IT di lingkungan manufaktur.
