Abstract

Durensari Tourism Village in Sawahan Village, Watulimo District, Trenggalek has a lot of tourism potential. Currently, the village community only focuses on river tourism, but actually there are many other tourist attractions in the village. The UPN Veteran East Java community service team held training and simulations of tourist attractions using GIS (Geographic Information System). With GIS technology, it is hoped that we can analyze the spatial aspects of an area to develop tourism potential into an object with optimal attraction so that it can attract the attention of both domestic and foreign tourists. Apart from that, more tourist attractions will help managers in compiling tour package service products. Based on the results of identifying tourist attractions in Durensari Sawahan Tourism Village, there are 3 types of tourist attractions in Durensari Village, namely Natural Tourism Attractions, Cultural Tourism Attractions, and Artificial Tourist Attractions. After conducting field visits, 10 new tourist attraction locations were identified which were then mapped using GIS technology. The next step is to increase participation from Pokdarwis Durensari members in managing tourism potential to become a tourist attraction which is then packaged in the form of tour packages that can be offered to tourists. The variety of existing tourist attractions can be an opportunity and strength for the Durensari Tourism Village to attract tourist visits

Abstract

This preliminary study aims to determine the daily profile of the power output generated from solar panels, with variations in the house’s roof angles of 15º, 0º, 15º. Tilt angle investigation expects to discover the impact of placing solar panels on the slope of the tile used on the house’s roof. The collecting data of this study was investigated the data of current and voltage every hour that produced by solar panel. Besides, this study also comparing the result of total energy output value for daily profile of solar panel during ten hour per day (start from 7 am to 5 pm). The results show that solar panels with an angle of -15º at 07:00 – 10:00 WIB have higher output voltage and current than other angle variations. At a tilt angle of 0º, the output voltage and current of the solar panel are higher at 11:00-14:00 WIB, while at a tilt angle of 15º in the afternoon. Based on observations, each solar panel with exposure for 10 hours obtained the total energy value for polycrystalline solar panels with a tilt angle of -15º of 258.44 Wh, solar panels with an angle of 0º obtained an energy value of 263.64 Wh, and a tilt angle of 15º obtained energy values 260.69 Wh. The photonic energy emitted for 10 hours is 2097.47 Wh. The energy efficiency value for each polycrystalline solar panel is 12.32% for the angle of -15º, the angle of 0º is 12.57%, and 12.43% for the angle of 15º. In conclusion, variations in the angle of the solar panels have significant effect on the voltage, current, and energy generated from polycrystalline solar panels in every hour. However, based on the data result the total energy exposure and the efficiency value for each variation angle has no significant different. Pyramid-shaped house roof construction has the advantage of increasing the value of the cross-sectional area of the tile, which has the opportunity to install wider-sized solar panels so that a greater value of electrical energy is obtained.

Abstract

This research presents the design, development, and implementation of a mini smart car prototype that operates using Internet of Things (IoT) technology. The system is built around the ESP8266 microcontroller (Amica version), which functions as the core processing unit responsible for handling Wi-Fi communication and data processing. The motion of the car is controlled by an L298 motor driver module that regulates the operation of DC motors. The entire system is powered by a 3.7-volt rechargeable battery, ensuring portability and energy efficiency. The study discusses in detail the hardware configuration, software programming, and integration of IoT-based control through a web or mobile interface. Functional testing of the prototype, named MINIOT, focuses on evaluating the responsiveness, stability, and reliability of remote control operations. The results are expected to show that the system can effectively receive and execute user commands while transmitting real-time telemetry data, such as motor status and connection indicators. This project demonstrates the feasibility of low-cost IoT-based automation for small-scale robotic applications.

Abstract

The Maluku Province is a region with high seismicity that is vulnerable to liquefaction hazards, particularly in coastal areas with shallow groundwater levels and saturated soil conditions. This study aims to analyze soil behavior indices and liquefaction potential at the construction site of a fuel tank in Masohi, Central Maluku, using Cone Penetration Test (CPT) by comparing the methods of Cetin (2004) and Idriss–Boulanger (2014), as well as comparing the results with previous research by Latifi et al. (2023) using the methods of Olsen (1997), Juang (2003), and Robertson (1998) under different soil conditions. The classification results indicate a dominance of silty clay soils that are potentially susceptible to liquefaction. In the Masohi case study, relatively similar CSR patterns were obtained; however, the Idriss–Boulanger (2014) method yielded higher CSR values compared to the Cetin (2004) method. The CRR analysis revealed significant differences; the Idriss–Boulanger method exhibits higher sensitivity to changes in soil type and parameters, whereas the Cetin method tends to produce more stable values. A similar finding was observed in the study by Latifi et al. (2023), which demonstrated that soil characteristics and calculation formulations result in varying analysis outcomes across methods regarding liquefaction potential as indicated by CRR values.

Abstract

The construction of Probolinggo–Banyuwangi Toll Road Package 3 faces geotechnical challenges due to variations in the thickness of compressible soft soil layers, which may cause excessive settlement and embankment instability. This study aims to analyze the influence of existing soil conditions on settlement and embankment stability and to determine the most appropriate ground improvement methods based on variations in compressible soil thickness. The research employed a quantitative method using secondary data, including Standard Penetration Test (SPT) data, embankment material parameters, ground improvement parameters, and seismic data for pseudostatic analysis. The N-SPT values were corrected and correlated into soil parameters, which were then modeled using PLAXIS 2D finite element software with the Hardening Soil model. The analysis results indicate that at STA 42+675, with a soft soil thickness of 5.5 m, the settlement difference under existing conditions was 16.22 cm and was successfully reduced to 7.9 cm after applying a combination of bamboo piles and bamboo mattress. At STA 45+700, with a soft soil thickness of 12 m, the existing condition experienced collapse during the embankment construction stage, whereas the combination of Prefabricated Vertical Drain (PVD) and preloading produced stable conditions with a settlement difference of 6.54 cm and a seismic safety factor of 1.375. This study concludes that selecting ground improvement methods based on the thickness of compressible soil layers can effectively improve embankment stability and control settlement.

Abstract

Construction of embankments on soft soil often encounters stability issues due to low shear strength and high compressibility, particularly when the loading rate is not properly controlled. This study aims to analyze the effect of embankment loading rate on lateral deformation behavior of soft soil improved using preloading combined with Prefabricated Vertical Drains (PVD). The research is based on a case study of the Pekanbaru–Padang Toll Road STA 10+400. The methodology involves numerical analysis using the Finite Element Method (FEM), preceded by manual calculations to determine staged loading scenarios with target degrees of consolidation. Three loading rates were evaluated, namely 0,2; 0,3 and 0,4 m/week. The analysis focuses on settlement, safety factor, and lateral deformation. The results indicate that all loading rate variations produce similar final settlements (approximately 3,7 m) and meet the required degree of consolidation. However, significant differences are observed in lateral deformation and stability. Lower loading rates result in smaller lateral deformation and higher safety factors, indicating improved stability performance. Conversely, higher loading rates generate greater excess pore water pressure, leading to increased lateral deformation and reduced stability margins. It can be concluded that controlling the loading rate plays a critical role in minimizing lateral deformation and ensuring embankment stability on soft soil. A lower loading rate is more effective in providing sufficient time for consolidation and strength gain, thereby improving overall performance.

Abstract

Perencanaan fondasi tiang pancang pada struktur slab on pile memegang peranan penting dalam menjamin kinerja dan stabilitas struktur, khususnya pada kondisi tanah yang bervariasi. Pada Proyek Pembangunan Jalan Tol di Jawa Timur, hasil uji Pile Driving Analyzer (PDA) menunjukkan bahwa kapasitas daya dukung tiang pada beberapa titik tidak memenuhi nilai rencana, sehingga diperlukan evaluasi dan optimasi desain fondasi. Oleh karena itu, dalam penelitian ini dilakukan optimasi desain fondasi tiang pancang dengan membandingkan variasi dimensi tiang (diameter dan kedalaman). Dari hasil penelitian didapatkan bahwa dimensi fondasi tiang diameter 80 cm merupakan alternatif desain yang paling optimal. Hal ini ditunjukkan oleh kapasitas daya dukung sebesar 2003,8 kN terhadap gaya aksial 1804,174 kN, yang memberikan margin keamanan terbesar dibandingkan variasi lainnya. Dari sisi penurunan, diameter 80 cm menghasilkan nilai sebesar 25,41 mm, yang masih berada dalam batas izin yaitu sebesar 50 mm. Berdasarkan hasil tersebut, variasi diameter 80 cm dinyatakan sebagai alternatif desain yang paling optimal karena memberikan kombinasi terbaik antara kapasitas daya dukung yang tinggi dan penurunan yang masih terkendali.
