Get PDFPemetaan Kerusakan Jalan Dengan Metode Pavement Condition Index Pada Ruas Jalan Arteri Mojosari - Mojokerto Berdasarkan Sistem Informasi Geografis
Get PDFGood road infrastructure is crucial to support mobility and the economy in a region. The Mojosari – Mojokerto Arterial Road has experienced various types of damage due to the increasing number of vehicles passing through the road, especially heavy-duty trucks. The resulting pavement damage can increase the risk of accidents for road users. Several arterial roads in the Mojosari – Mojokerto direction are experiencing pavement damage. To obtain information on the level of pavement damage, the Pavement Condition Index (PCI) approach method is used with the formula (PCI = 100 – CDV) with a numerical index value output ranging from 0 – 100 based on the level of damage, type of damage, and dimensions of the damage. This study aims to find the index value of the level of pavement damage on the Mojosari – Mojokerto Road section using the Pavement Condition Index (PCI) method and also to map the condition of road damage in the study area using a Geographic Information System (GIS). The road damage data collection survey was conducted from April 4 to 22, 2025, from 08.00 to 17.00. The types of damage found at the research location include sungkur, potholes, edge cracks, bleeding, patches, alligator skin cracks, grooves, checkerboard cracks, longitudinal cracks, transverse cracks, and joint cracks. The results of the percentage of damage values analyzed using the Pavement Condition Index (PCI) method are as follows: Airlangga Street 76 (Very Good), Gajah Mada Street 80.5 (Very Good), Jalan Raya Pekukuhan 81.33 (Very Good), Ahmad Yani Street 85 (Very Good), Ngranggon Street 79.3 (Very Good) with a value range of 71-85 based on the Pavement Condition Index (PCI) method. The road damage condition value will be used to create a thematic map of road damage values for each road segment

Get PDFThe advancement of digital technology has encouraged the emergence of web-based e-ticketing systems such as Kita Garuda, developed by PSSI to facilitate online ticket purchases for the national football team matches. However, variations in processes and users’ ability to access digital technology still create challenges and discomfort. This study aims to analyze the factors influencing user acceptance of the Kita Garuda website using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2), modified with the addition of Service Satisfaction, Continued Intention, and Psychological Discomfort variables. The Partial Least Square Structural Equation Modeling (PLS-SEM) method was employed to examine the relationships among variables and to test the moderating effect of Psychological Discomfort. The results show that within Intrinsic Motivation, Habit is the most dominant factor influencing Continued Intention, while Hedonic Motivation is the weakest. Within Extrinsic Motivation, Facilitating Condition has the strongest effect, whereas Price Value is the least influential. Service Satisfaction was not proven to be a significant mediator between motivation and Continued Intention. Moreover, the multi-group analysis indicated that respondents with high levels of Psychological Discomfort demonstrated stronger relationships among variables compared to those with lower levels. These findings provide implications for Kita Garuda’s management to enhance sustainable usage by focusing on user motivation, service quality, and psychological experience in using the e-ticketing platform
PENERAPAN CONTENT-BASED FILTERING DAN NAÏVE BAYES CLASSIFIER PADA REKOMENDASI DOSEN PEMBIMBING TUGAS AKHIR
Get PDFThe selection of thesis supervisors is a crucial factor that significantly influences students’ success in completing their undergraduate theses. Limited access to information regarding the alignment of lecturers’ expertise often leads to inaccurate supervisor assignments. This study proposes a supervisor recommendation system based on text mining by integrating Content-Based Filtering (CBF) and the Naïve Bayes Classifier (NBC). The dataset consists of lecturers’ scientific publications as proxies for their expertise and a collection of student thesis titles from 2022–2024 as test data. The preprocessing stage includes translation, case folding, tokenization, stopword removal, and stemming. CBF measures the similarity between thesis titles and publications using TF-IDF and cosine similarity, while NBC models the probability of topic relevance through Laplace smoothing. The scores from both methods are combined using a weighted sum approach to generate the final ranking of recommended supervisors. The evaluation results indicate that the hybrid CBF+NBC approach outperforms each method individually, showing a consistent improvement in accuracy across the years. Specifically, for the 2024 validation dataset, the system achieved 86% accuracy under the optimal weighting scheme, highlighting the effectiveness of combining content similarity and probabilistic modeling in mapping the compatibility between lecturers and students. This study provides a more objective, transparent, and balanced framework for supervisor selection, and it can be replicated in other academic programs with similar characteristic

Get PDFapplications of this composite is as an effective adsorbent, capable of absorbing metal ions. Bagasse ash is
a material that contains a relatively high amount of silica. In this study, bagasse ash will be utilized as a
constituent in the fabrication of silica-carbon composites. In this study, bagasse ash was extracted with
NaOH at concentrations of 1N, 1.5N, 2N, 2.5N, and 3N. The filtrate from the extraction, in the form of
Na2SiO3, will undergo dilution with demineralized water at a ratio of 1:1, 1:2, 1:3, 1:4, and 1:5. The
variation in NaOH concentration and Na2SiO3 dilution ratio is designed to ascertain the impact of these
conditions and conditions with the Si/C content most analogous to the optimum Si/C ratio. The findings
indicated that the optimal silica carbon composite was achieved at a NaOH concentration of 1.5, with a
silica content of 68.3% and a carbon content of 25.76%, resulting in a Si:C ratio of 2.65:1. In contrast, a
NaOH concentration of 2N, with a silica content of 55.58% and a carbon content of 35.97%, yielded a Si:C
ratio of 1.54:1. The results of the XRD analysis demonstrated that the silica carbon composite did not
exhibit any crystalline phase peaks. Instead, a range of 15–30° was observed, with the highest peak located
