Abstract

Proyek yang berhasil adalah yang menyelesaikan semua fitur yang dipersyaratkan sesuai jadwal dan biaya. Under-estimate dalam estimasi proyek dapat mengakibatkan understaffing, under-scoping, dan jadwal yang terlalu pendek. Over-estimate dalam estimasi proyek cenderung mengakibatkan biaya lebih besar dan memperpanjang waktu proyek, menghambat penggunaan sumber daya untuk proyek berikutnya. Pemanfaatan teknologi digital telah menciptakan e-government, sebuah bentuk baru birokrasi pemerintahan di negara maju. Dalam penerapan e-government, diperlukan penyesuaian birokrasi, regulasi, visi pimpinan daerah, alokasi anggaran, dan peningkatan kemampuan SDM. Tantangan utama dalam implementasi e-government termasuk birokrasi yang rumit, regulasi yang belum memadai, serta kurangnya pemahaman teknologi informasi oleh DPRD. Pengelolaan anggaran dan proyek e-government menjadi kunci keberhasilan implementasi e-government, namun masih sering terjadi pemotongan anggaran dan pengalokasian yang kurang tepat. Penelitian ini bertujuan menganalisis metode estimasi untuk proyek software e-government di Indonesia dan merekomendasikan model estimasi yang sesuai.

Abstract

In this modern era, Indonesian society widely utilizes social media, particularly Twitter, as a means to express their opinions. Every day, various opinions of Indonesian citizens are disseminated on this platform, including their views on prospective presidential candidates for the year 2024. Analyzing public opinions regarding prospective presidential candidates in 2024 is crucial to understanding the sentiment of the people toward these candidates. Such sentiment analysis can be conducted using deep learning techniques such as IndoBERT to acquire knowledge regarding the classification of sentiments as positive, neutral, or negative. IndoBERT is employed to generate vector representations that encapsulate the meaning of tokens, words, phrases, or texts. These representation vectors can then be input into a classification model to perform sentiment analysis. The sentiment classification model undergoes testing with a diverse set of tweets in the test dataset, which represent a wide range of public opinions. The evaluation results indicate an overall accuracy rate of 80%, with precision rates of 62% for negative sentiment, 81% for neutral sentiment, and 85% for positive sentiment. Additionally, the recall rates for each sentiment are 64% for negative, 81% for neutral, and 84% for positive, with corresponding F1-scores of 63%, 81%, and 85%, respectively.

Abstract

Public health has become a significant focus in this modern era due to the increasing number of people suffering from various diseases. Unhealthy diets and lack of physical activity are often associated with multiple health problems, one of which is obesity. Several studies have been conducted to develop food recommendation systems for individuals with obesity, using K-Means and Random Forest algorithms to provide food recommendations based on user-specific aspects. However, these studies do not provide supporting information, such as physical activity recommendations to address fitness issues or lack of physical activity. This study develops a diet and physical exercise recommendation system for individuals with obesity using a combination of K-Means and Random Forest. The system categorizes and classifies foods and physical exercises and provides customized recommendations based on user data analysis. The accuracy of the system was evaluated using the MAPE metric, with the highest accuracy for dietary food recommendations being 99.03% for the non-vegan lunch diet meal recommendation and the lowest being 70.74% for the vegan morning meal diet recommendation. The MAPE for physical exercise recommendations was consistently at 26.35%, indicating a stable accuracy of 73.65%. The test results show that the system recommends diet and physical exercise accurately.

Abstract

This research aims to design and develop an efficient funding website for Micro, Small,and Medium Enterprises (MSMEs) in Mataram City using the Simple Additive Weighting(SAW) method at PT XYZ. The background of the research is based on challenges suchas the manual selection of MSMEs, which can be time-consuming and prone to errors incalculating scores or values. Additionally, the criteria scores lack a definite average valuefor each category, and there is a risk of losing MSME application documents due todisorganized collection, leading to scattered documents. In this advanced era, manycompanies use websites to support their programs, while PT XYZ still lacks such aplatform to support its funding program. Given these challenges, a website is needed tosupport the funding program and address existing issues. This research uses a qualitativeapproach, collecting data through literature studies, interviews, and observations. Theresults of this research show that using the Simple Additive Weighting (SAW) methodyields consistent final values in both manual and program-based tests and enables fasterselection
