Abstract

The unknown exact flexural strength of low carbon steel, Randu ribs wood, paving stones, and lightweight bricks is a problem faced. The purpose of this research is to obtain the flexural strength of low carbon steel, Randu ribs, paving stones, and lightweight bricks. The research method is carried out through the preparation of low carbon steel specimens 16mmx200mm, Randu ribs 40mmx60mmx250mm, paving stones 55mmx100mmx200mm, lightweight bricks 95mmx100mmx300mm, Tarno Grocky flexural testing machine settings, flexural testing support distance for low carbon steel 160mm, Randu ribs 220mm, paving stones 170mm, and lightweight bricks 260mm, flexural testing of each material, making flexural stress and deflection curves for low carbon steel, and analyzing flexural test results. The results of the study showed that the flexural strength of low carbon steel was 698 MPa at a deflection of 1.1 mm, the flexural strength of Randu rib wood in an upright position was 40.7 MPa, in a horizontal position was 55.5 MPa, in a normal position of paving stone in an upper position (normal) was 6.64 MPa, in a lower position (upside down) was 6.62 MPa, and in a lightweight brick was 1.28 MPa, which implies that the type of material, the distance between supports and the cross-section of the specimen greatly affect its flexural strength, except for ductile materials for low carbon steel which do not have flexural strength, but have yield strength at a certain deflection.

Abstract

This study aims to design, implement, and test a prototype that automates three functions, namely watering, fertilizing, and pest control based on Arduino Uno with the ability to directly monitor soil moisture and pH. This system is equipped with four main types of sensors. Soil condition monitoring involves an FC-28 soil moisture sensor and a soil pH sensor, water level measurement involves an HC-SR04 ultrasonic sensor, and pest detection in the plant area involves a RIP sensor. All data obtained from these sensors is then processed by the Arduino Uno microcontroller to automatically activate actuators such as water pumps, liquid fertilizer pumps, buzzers, and DC motors according to soil conditions and plant needs. Prototype testing was conducted on simulated land with various scenarios of moisture, soil pH, and pest activity. The test results revealed that the system was proven to be able to significantly optimize water and fertilizer utilization, as well as reduce pest disturbances that could potentially damage plants.  In addition, this system also displays the operational status directly through an LCD screen, making it easy for users to monitor. The advantage of this system is its multi-function integration in a single device that is cost-effective and easy to operate. In the future, the functionality of this system can be improved through integration with Internet of Things (IoT) technology, enabling remote monitoring and control with greater efficiency. More broadly, this study is expected to support increased production and sustainable agricultural practices in Indonesia.

Abstract

This study aims to analyze the differences in motorcycle traffic flow (Q) during the morning and afternoon peak hours as an indicator of roadway operational performance, referring to the Indonesian Road Capacity Guidelines (PKJI) 2014, with a case study on Mawar Street–Wijaya Kusuma Street, Jember Regency. The research data were obtained from 12 observation points through traffic surveys that recorded motorcycle traffic flow in vehicles per hour (veh/h). The analytical methods used include descriptive statistical analysis, normality testing, and paired sample t-test. The results show that the average motorcycle traffic flow during the morning peak hour is 115.58 veh/h with a standard deviation of 62.97, while during the afternoon peak hour it is 63.25 veh/h with a standard deviation of 28.57. The paired sample t-test yields a significance value of 0.015 (p < 0.05), indicating a statistically significant difference between morning and afternoon traffic flows. These findings suggest that the level of roadway capacity utilization is higher during the morning peak hour, which is closely associated with dominant routine travel activities such as commuting to work and school. The results of this study are expected to serve as a basis for evaluating roadway operational performance and to support traffic management and traffic engineering planning aimed at improving road network performance and reducing congestion.

Abstract

Mawang Village occupies a strategic position as a buffer zone integrating the administrative center of Gowa Regency with other growth centers, featuring the ecological asset of Lake Mawang, which holds significant potential for ecotourism development. However, a discrepancy exists between spatial planning policies and the actual development of facilities and infrastructure on the ground. This study aims to identify the availability, accessibility, and physical feasibility of regional facilities and infrastructure as a fundamental database for area development. The method employed is descriptive-quantitative with a comparative analysis approach referring to the SNI 03-1733-2004 standards and spatial analysis. The findings indicate that religious and commercial/service facilities exhibit very high service levels with surplus conditions, while basic health facilities and early childhood education remain below minimum service standards. Spatially, the distribution of facilities tends to be concentrated along the main corridor, creating accessibility disparities for residents in inner residential areas. The collector road infrastructure is functionally adequate but lacks pedestrian facilities, while local roads suffer from pavement quality degradation. Furthermore, Lake Mawang, as a primary tourist attraction, still lacks basic supporting facilities. The implications of this research emphasize the need for equitable distribution of health facilities, revitalization of road quality, and the formulation of a comprehensive spatial detail plan for the lake area to achieve sustainable regional development based on local potential.

Abstract

The rapid expansion of construction activities has led to increased concrete consumption, resulting in excessive exploitation of natural aggregate resources and growing environmental concerns. To mitigate this issue, ceramic waste has been investigated as an alternative material in concrete production. This study examines the effect of ceramic waste powder used as a filler on the workability and compressive strength of concrete. Ceramic waste powder was applied as a partial replacement for fine aggregate at proportions of 0%, 15%, 25%, 35%, and 45%. The concrete mixtures were produced using Ordinary Portland Cement Type I, natural sand, crushed stone as coarse aggregate, and potable water, all conforming to Indonesian National Standards (SNI). Workability was assessed through slump tests in accordance with SNI 1972:2008, while compressive strength tests were performed on cylindrical specimens at 28 days following SNI 1974:2011. The compressive strength for each mixture was determined from the average of three specimens. The results show that increasing ceramic waste content slightly reduced slump values, from 17.20 cm in the control mix to 16.60 cm at 45% replacement, although all mixtures met the required workability standards. A gradual decrease in compressive strength was also observed, from 17.79 MPa to 16.65 MPa at the highest replacement level. However, this reduction was not significant, indicating that ceramic waste powder can be used in normal-strength concrete without substantially affecting performance. The utilization of ceramic waste therefore represents a sustainable alternative to reduce natural aggregate consumption while maintaining acceptable concrete properties.

Abstract

Heavy equipment effectively plays a key role in ensuring productivity and efficiency in the precast concrete industry of spun pile concrete at PT Adhi Beton Purwakarta. One of the heavy equipment that plays an important role is the mobile crane, especially for moving large concrete components. In this study, field data was processed by analyzing the productivity and efficiency of the Tadano GR-500EXL type mobile crane with a capacity of 50 tons. Current problems are high idle time, lack of operational synchronization, and suboptimal utilization of technological features on the crane unit. The results show that spun pile concrete weighing 6.78 tons based on the analysis of heavy equipment productivity is 40.68 tons/hour with the number of mobile crane heavy equipment needed as many as 2 units, and the efficiency for crane heavy equipment reaches around 68%. The amount of productivity and needs are to support the target of achieving precast concrete production, especially spun pile concrete. Thus, it is expected that the amount of productivity and the number of mobile crane heavy equipment needs are optimal to support production.

Abstract

The foundation of turbine machines in industrial buildings must be able to withstand static and dynamic loads caused by operational vibrations. Generally, reinforced concrete block foundations are used due to their good stability. However, under certain conditions such as limited land, decreased soil bearing capacity, and the need for structural rehabilitation, their application becomes less effective. Therefore, this study aims to analyze the use of Micropile foundations as an alternative for turbine machine foundations at Candi Baru Sugar Factory, Sidoarjo.The research method includes literature studies, soil data collection through Cone Penetration Test (CPT), machine technical data analysis, and the design and analysis of Micropile foundations. The analysis covers bearing capacity, settlement, dynamic response, pile cap design, and cost estimation.The results indicate that Micropiles with a diameter of 0.20 m, a length of 2 m, five piles, and a pile cap size of 2 m × 2 m × 4.5 m are able to safely and stably support the machine load. In addition, this system is considered more efficient in terms of construction time and implementation. Therefore, Micropile foundations are recommended as an effective and economical alternative for turbine machine foundations.

Abstract

This research looks into how site managers in construction projects in Malang City manage and improve their use of human resources. The research is driven by the significance of effective human resource management in ensuring project success and the lack of studies focusing on the operational strategies of site managers within a local context. This study uses a quantitative method that is both descriptive and analytical. It involves giving out a survey to 40 people, including site managers, contractors, and foremen. The independent variables include leadership and supervisory style, human resource planning and workforce allocation, training and competency development, team communication and coordination, performance monitoring and evaluation, as well as motivation and welfare. The dependent variable is the degree to which human resource management is optimized. The results of validity and reliability tests indicate that all research instruments are valid and reliable. Multiple linear regression analysis shows that leadership and supervisory style, along with human resource planning and workforce allocation, have a significant partial effect on improving HRM practices. Other variables have a positive but statistically insignificant partial effect on the estate. Overall, the management of human resources in construction projects in Malang City is considered to be fairly good. This study confirms that leadership and workforce planning are the main strategic factors for site managers in improving the effectiveness of human resource management in construction projects.

Abstract

The Regional Public Library of Sidoarjo Regency plays an important role as a public facility in supporting the development of community literacy. Along with population growth and the advancement of the education sector, the library is required to provide spaces that are comfortable, safe, and inclusive for all users. However, existing conditions indicate various architectural problems that potentially hinder the optimal function of the library. This study aims to identify architectural issues at the Regional Public Library of Sidoarjo Regency, including building conditions, spatial layout, user comfort, and the availability of thematic literacy facilities and inclusive spaces. The research method employed observation and literature review. Field observation was conducted to document the actual conditions of the building and library facilities, while the literature review focused on library standards, building regulations, and relevant architectural theories. The results show that although the library building is structurally adequate, the quality of space has not fully met the required standards of comfort, safety, and functionality. The spatial arrangement remains conventional and lacks flexibility, limiting its ability to support diverse literacy activities. In addition, thematic literacy facilities and the application of inclusive design principles are still limited. This study concludes that architectural development efforts are needed, focusing on improving spatial quality, implementing adaptive spatial planning, and providing more diverse and inclusive literacy facilities. The findings are expected to serve as a reference for future development planning of the Regional Public Library of Sidoarjo Regency in order to enhance its role as an educational public space and a community literacy center.
