Abstract

Pondasi merupakan struktur bawah dari suatu bangunan yang berfungsi menopang strukur atasnya. Pondasi berfungsi menahan beban-beban dari atas, sehingga pondasi didisain dapat bertahan jika terjadi gempa ataupun kelebihan beban dan tidak boleh gagal terlebih dahulu. Beban dari struktur atas didistribusikan melalui kolom dengan nilai tegangan yang diijinkan sesuai dengan nilai daya dukung tanah. Ada dua jenis pondasi yaitu pondasi dangkal dan pondasi dalam. Pondasi dalam merupakan salah satu jenis pondasi yang digunakan untuk menyalurkan beban struktur ke lapisan tanah keras yang memiliki kapasitas daya dukung tinggi yang letaknya cukup dalam di dalam tanah. Studi analisa daya dukung tanah pondasi dalam yang menggunakan mini pile berukuran 25 x 25 cm dilaksanakan pada proyek pembangunan gedung sekolah SMK 1 Rangas Kabupaten Mamuju dengan menggunakan data sondir (CPT) sebanyak 2 titik dengan masing-masing kedalaman 15,8 m dan 5,0 m. Kedalaman perencanaan pondasi terlebih dahulu harus dihitung dan ditentukan kapasitas daya dukung rencana. Tujuan dari studi ini yaitu menghitung dan mengetahui nilai daya dukung ultimit aksial tiang pancang tunggal dalam kelompok tiang dengan metode analitis dan mengetahui besarnya daya dukung kelompok tiang. Desain pondasi meliputi kekuatan satu tiang pondasi, efesiensi kelompok tiang dan perhitungan distribusi beban pada tiang. Berdasarkan hasil analisis didapat pondasi mini pile mampu menahan beban yang bekerja diatasnya, sehingga pondasi dikategorikan aman. Dari hasil perhitungan diperoleh efesiensi kelompok tiang yaitu 83,08%, jumlah tiang 3 buah dengan daya dukung kelompok tiang 68,29 ton yang mampu menahan gaya aksial yaitu 59,54 ton.

Abstract

Starting with COVID19, almost everyone around the world uses the internet, even to the worrying stage, namely internet addiction. Several studies report that the level of addiction to using the internet network is getting higher even though COVID19 has subsided. Teenagers have not been able to choose useful internet connection activities and they are more prone to experiencing bad influences from the social environment. To overcome this they need support from psychologists so they can prevent and diagnose early before they become sufferers of severe internet addiction. But on the other hand, the number of psychologists who can help is still very limited, especially in small towns. In addition, economic factors and limited time for parents to accompany their children to visit psychologists are the main obstacles. Therefore it is necessary to find a solution that can overcome the limitations and barriers to adolescents in obtaining services from a psychologist. One solution to this problem is to build an expert system that can work as a psychologist. The purpose of this research is to build an expert system application for diagnosing internet addiction using the backward chaining method. Internet addiction level is categorized in low, medium and high. System testing is carried out using black box testing which allows experts to obtain a set of output conditions that will carry out all functional requirements of the program. This test shows that the inout and output data has been running as expected.

Abstract

National parks serve as excellent conservation sites to observe the splendor of natural events, particularly for viewing unique, endangered, and protected plant and animal species. This research aims to understand how the local people perceive the presence of Gandang Dewata National Park (TNGD) in Sikamase Village. The study employs a detailed interview technique combined with a qualitative descriptive method. Findings from this research indicate that the perception of Gandang Dewata National Park among the local population in Sikamase Village is that it can stimulate economic growth for the surrounding community. The management, specifically BBKSDA Makassar, frequently engages with the local residents, particularly those in the surrounding villages, to promote awareness. Collaborative efforts between the community and park management are undertaken to ensure the ongoing protection of TNGD. The communication established by BBKSDA Makassar extends from management practices to community empowerment initiatives in the buffer areas of TNGD. The security in the TNGD region is notably effective, primarily due to regular patrols conducted by management groups, including the forestry police and the Polhut Partner Community (MMP), which significantly reduces the likelihood of encroachments in the area. The establishment of TNGD in Mamasa Regency is viewed positively by the locals, demonstrated by their support for management efforts and active participation in roles such as Polhut Partner Communities (MMP), Fire Care Communities (MPA), and Village Facilitators (Fasdes) aimed at fostering sustainably managed conservation zones. Although management has extensively communicated with local government and the community, disagreements still persist on issues like illegal hunting, the collection of forest resources without proper authorization, and land encroachments.

Abstract

Personal financial literacy is a vital skill for university students, yet many struggle to track their daily expenses due to time constraints and low awareness. This study aims to design and develop a web-based Student Expense Tracking System using Optical Character Recognition (OCR) technology to address this issue. The system allows users to automatically extract and record spending information from receipt images, reducing manual input and improving financial awareness. The development followed the Web Development Life Cycle (WDLC) using the Waterfall model, comprising planning, design, development, and testing phases. Visual Studio Code, Python 3, and Tesseract OCR were employed in system implementation. Wireframes and mockups guided the interface design, while backend development focused on data storage and OCR integration. Functionality testing showed a 100% pass rate across ten scenarios, validating the system's performance in image processing, budget management, and spending visualization. Usability testing using the Post-Study System Usability Questionnaire (PSSUQ) with 30 participants yielded a mean score of 4.45 out of 5, indicating a high level of user satisfaction. The system scored highest on ease of use (4.6), visual design (4.7), and recommendation likelihood (4.8), confirming its intuitive interface and appeal. Slightly lower scores in user confidence (4.1) and data organization (4.2) point to opportunities for interface refinement and improved user guidance. This research concludes that OCR can effectively support financial tracking for students. Future enhancements with NLP and machine learning are recommended to automate expense categorization and improve analytical capabilities.

Abstract

Despite being equipped with mud pockets, the Sekka-sekka Dam still requires routine maintenance due to sediment accumulation in the Primary Canal. Sediment modelling has become an effective approach to identify areas with high sedimentation to make maintenance more focused and efficient. This research aims to determine the sedimentation patterns that occur, model the transport of bed sediment, and analyse the magnitude of bed sediment transport in the D.I Maloso primary canal using Hec-Ras software. The analysis was conducted using a Quasy-Unsteady Flow approach, with input comprising cross-sectional data of the canal, a flow discharge of 33.81 m3/s, and the characteristics of the bed sediment. The simulation results indicate the presence of sediment transport along the canal, with a dominance of fine sand and medium sand fractions. The total sediment transport over one month in the upstream reached 14,551 kg/month with a sediment thickness of 0.00227 m, in the midstream 35,351 kg/month (0.00551 m), and downstream 23,791 kg/month (0.00371 m). The shear stress values were 0.0080 Pa, 0.0078 Pa, and 0.0076 Pa respectively, with a fall velocity of 0.26 m/s upstream, and 0.2 m/s in the midstream and downstream. The average sediment concentration over three months was 0.3 mg/l, with the highest concentration recorded downstream at 4.8 mg/l. This modelling demonstrates the distribution of transported sediment in the canal, with the highest accumulation downstream due to the decrease in flow velocity and shear stress.
