Abstract

This research aims to develop a remote control system for waste collection machines using Arduino Nano and LoRa communication modules. The background of this research is the need for an effective remote control system to manage waste collection machines automatically. This system is designed to optimize the machine control process through stable wireless communication. The research process begins with system design, including block diagrams and flowcharts for remote control transmitters and receivers. The transmitter uses an Arduino Nano to read input from the button and send data via the LoRa module. The receiver receives signals from the transmitter, then controls the motor using the L298N motor driver module based on the data received. The research results show that the system can control the motorbike accurately according to the signals received, including forward, backward, right turn and left turn movements. The system is also capable of handling button combinations for more complex motor control. The use of Fritzing and Visual Studio Code in the design and programming process makes system implementation and testing easier. This research provides a practical solution for remotely controlling waste collection machines with LoRa communication.

Abstract

The Jati Area in Padang City is one of the urban regions affected by flooding and waterlogging, particularly during the rainy season. The flooding issue in this area is not only caused by the insufficient capacity of the drainage channels but also by the lack of understanding regarding the hydrological characteristics of the region. Therefore, a hydrologically based modeling approach is essential to analyze and predict the response of the catchment area to rainfall, surface runoff discharge, and the effectiveness of the existing drainage system. In this study, the author models the drainage system in the Jati area using the HEC-HMS program, with the aim of obtaining the peak discharge value during extreme rainfall events and determining the timing of the maximum discharge. HEC-HMS is a widely used software for hydrologic modeling, particularly for simulating the runoff process from a watershed area. The research consists of three main stages: data collection, data processing, and drawing conclusions from the results. Based on the simulation results of the hydrologic modeling analysis of the drainage network in the Jati area, it was found that the channels at certain nodes are unable to accommodate the design discharge load, resulting in flooding due to the insufficient capacity of those channels. The results of this study can be used by policymakers for the redesign of drainage infrastructure, such as modifying the channel dimensions from a base width of 6.5 m, 6.8 m, and 6.8 m at reach 9, reach 10, and reach 11 respectively, to 8.5 m based on the peak discharge from the simulation results, which is 37.5 m³/s.

Abstract

The increasing amount of plastic waste is one of the main challenges in current waste management. One solution that can be implemented is processing plastic waste into value-added products, such as paving blocks. This study aims to design and develop an efficient melting machine for processing plastic waste into paving blocks. The methods used in this research include the design phase using Solidworks 2022, prototyping, and testing of the melting machine. During the design phase, an analysis of the melting machine requirements was conducted, including capacity, operating temperature, and safety aspects. The design of the melting machine was carried out by considering ergonomic aspects, energy efficiency, and the ability to produce high-quality paving blocks. This process involved the use of materials resistant to high temperatures and thermal insulation materials to maintain optimal operating temperatures. The melting machine was then tested under various operational conditions to evaluate its performance. The melting machine must reach the required operating temperature of 200°C to melt plastic waste without damage. PET (polyethylene terephthalate) plastic waste processed into paving blocks has a compressive strength of 11.09 MPa and meets Class D quality standards in accordance with SNI 03-0691-1996

Abstract

The building envelope plays a crucial role in controlling heat transfer from the outside environment to the interior of the building, which in turn affects occupant comfort and building energy consumption. This study aims to determine the existing Overall Thermal Transfer Value (OTTV) of the Student Activity Center of Universitas Indonesia (PUSGIWA UI) building, as per the applicable Indonesian National Standard (SNI). As well as providing optimization solutions to obtain OTTV values that comply with the Indonesian national standards. The OTTV calculation results of the PUSGIWA UI building show a value of 37.80 W/m², which exceeds the SNI standard limit of 35 W/m². This indicates that the building envelope at PUSGIWA UI is not yet effective in protecting and maintaining the thermal comfort conditions within the building environment. The highest OTTV value is found on the north orientation side of the building, at 42.77 W/m². As optimization, it is recommended to replace the glass section with Asahimas Sunergy Clear glass, which has a low reflection value and better solar energy shading capability compared to the existing glass. The application of this glass can reduce the OTTV value to 28.96 W/m², which already meets the thermal comfort standards of a building. This study contributes to the planning of more environmentally friendly building envelope designs and energy efficiency.

Abstract

As one of the main fillers in concrete and asphalt mixtures, aggregate must comply with the required material standards. Aggregate sieve analysis is one of the tests that must be carried outbefore making a concrete Job Mix Formula (JMF). Aggregate sieve analysis testing is an important step to determine the size of the aggregate particle used in concrete mixtures and asphalt mixtures. Aggregate sieve analysis testing aims to analyze the aggregate grain size distribution, determine the maximum grain size of the aggregate used, ensure its conformity with technical specification standards and evaluate its impact on the quality and performance of construction materials. In this study, the combined percentage or percentage of coarse aggregate and fine aggregate was determined using analytical methods. This method involves using a series of sieves specific sizes to separate and measure the proportion of particles from the aggregate to be tested. Previous research shows that the distribution of aggregate gradations effect the stability, strength and durability of construction materials. The aggregate used as a test sample came from the Batang Kuranji river. The coarse aggregate used is 2000 grams in surface dry condition (SSD) and 1000 grams for fine aggregate. Dry surface condition on the aggregate were obtained after the aggregate was dried in an oven for 24 hours. The maximum aggregate size used for this test is 40 mm. Finenes Modulus (FM) of the material used as a test sample has accordance the required material fineness value. The results of the sieve analysis test provide a recommendation for a combined percentage of coarse aggregate of 64.8% and fine aggregate of 35.2%. Besides that, from the aggregate sive analysis test, it is known that the FM values obtained were 7.22 for coarse aggregate and 3.09 fine aggregate in the Batang Kuranji river.

Abstract

Accurate prediction of beam deflection is crucial in civil engineering structural design, ensuring both safety and functionality. This study investigates how the physical and material properties of a beam relate to the maximum deflection under various loading conditions. We used an analytical approach, applying classic deflection equations derived from Euler-Bernoulli beam theory, which assumes linear elasticity and small deformations. Our case study features a simply supported beam with a 4000 mm span. It's made of concrete with a 30 MPa compressive strength and reinforced with steel having a 390 MPa yield strength. The analysis includes common loading scenarios like concentrated and uniformly distributed loads to evaluate their impact on deflection. The calculations show a maximum deflection of 18.78 mm, which exceeds the allowable limit of 14.17 mm set by SNI 2847:2019. This study demonstrates that mathematical models reliably estimate structural behavior and are effective for design decision-making. These findings highlight the importance of analytical proficiency in structural engineering, especially during initial design and assessment phases. Integrating theoretical models with practical data improves the accuracy of structural analysis, contributing to safer and more efficient construction practices.

Abstract

 Padang State Polytechnic (PNP), one of the first 17 polytechnics in Indonesia, is committed to creating a comfortable academic environment with adequate facilities and harmonious interaction between lecturers, staff, and students. Collaboration with many companies has increased the number of students and study programs admitted each year. However, the construction of facilities and infrastructure has reduced green open space by 26.88%. The construction of Buildings AB and E in 2012 has impacted the comfort and health of Building F users, obstructing air circulation and natural lighting, and increasing the demand for water and waste management. Recommendations are needed to convert Building F into a green building according to the Minister of Public Works and Housing Regulation No. 21 of 2021 to optimize natural resources, reduce environmental impact, and enhance comfort. This research aims to develop retrofit recommendations, including replacing window openings, adding green areas, planning natural lighting, and improving waste and wastewater management systems. Data was collected through literature review, observation, quantitative methods, interviews, and documentation. The initial assessment of Building F scored 21.81% according to the Checklist for Existing Buildings in the Green Building Performance Assessment, indicating a significant need for improvement. The implementation of the recommendations will potentially increase Building F's score to 70.30%, placing it in the "MADYA" category, reflecting better sustainability and efficiency standards.. This demonstrates the success of the recommendations provided and the potential to improve building performance in the future

Abstract

The city of Solok, which is located in West Sumatra, with a population of 81,059 people, has limited agricultural land of 875.6 hectares and produces 5,430 tons of rice, which has experienced a decline in rice production since 2019. This decline in rice production was caused by irrigation constraints, which prompted the government to implement the Acceleration Program for Irrigation Water Use Improvement/P3TGAI to improve the irrigation network which involves community participation, in this case the Water User Farmers Association (P3A). This research compares the efficiency of cost planning and budgeting for irrigation improvements in the Bdr Lembang irrigation area using the Unit Price Analysis (AHSP) approach. Data collected includes primary and secondary surveys, with a focus on existing irrigation conditions. The results showed that there are 5 determinants of the success of the self-management project for P3-TGAI, such as good communication between parties involved in the project (95.95); appropriate/appropriate work planning (91.89); monitoring of the project by the parties involved (89.19); ability to solve project problems by the parties involved (83.78); proper cost management by the parties involved (83.78). Then, there are 10 aspects that determine the success of P3-TGAI self-management projects, these factors are formed from the highest index in each aspect surveyed. analysis show the difference between the implementation of self-management and contracting in the use of materials and personnel because the volume of the channel length in self-managed work is 368 meters, whereas if it is contractual the channel length volume is 345.32 meters. Thus highlighting the need for effective resource management in irrigation projects.

Abstract

This research discusses the analysis of the rotary system sand sieving machine frame with a capacity of 10 kg using Solidworks 2018 with the Finite Element Analysis (FEA) Method. This research aims to overcome manual problems in the sand sieving process in building construction by developing an efficient and reliable automatic machine. Technology is identified as a basic need of modern society because of its ability to increase efficiency and productivity in various activities. Sand, as an important construction material, must be sieved from rocks and gravel before use. Current manual sieving processes require a lot of effort and time, prompting the need for automated solutions such as the rotary sand sieving machine designed in this research. Machine design focuses on frame strength as the main component that supports operational loads. The frame strength analysis was carried out using Solidworks 2018 with the FEA method to ensure its safety and resistance to a load of 10 kg. The analysis results show that the machine frame can bear operational loads well. The maximum stress that occurs in the frame is 9.248 N/m2, far below the yield strength of the material used. The maximum deformation (displacement) that occurred was 1,058 mm, mainly concentrated in the critical areas analyzed. Safety factor analysis shows that the frame meets safety standards with a safety factor of 2.7, exceeding the expected value for construction industry applications
