Abstract

Ketahanan konstruksi bangunan gedung selama masa layan yang direncanakan sangat ditentukan oleh kualitas mutu elemen strukturnya. Nilai kuat tekan merupakan salah satu parameter yang digunakan untuk mengevaluasi mutu elemen struktur beton. Teknologi hammer test (HT) dan ultrasonic pulse velocity (UPV) adalah metode uji tak merusak yang sering digunakan untuk menentukan kuat tekan beton pada struktur di lapangan. Tujuan penelitian ini adalah untuk memprediksi kuat tekan beton pada elemen struktur balok, kolom, dan pelat dengan menggunakan metode HT dan UPV. Metode penelitian dilakukan melalui pengujian lapangan dan analisa berdasarkan standar SNI 03-4430-1997 untuk HT dan standar SNI C597-2012 untuk UPV. Objek penelitian ini adalah elemen-elemen struktur pada salah satu bangunan gedung perkuliahan di Politeknik Negeri Manado. Total pengujian HT dan UPV yang diambil sebagai sampel adalah 20 titik pada kolom, balok, dan pelat. Hasil pengujian menunjukkan bahwa prediksi kuat tekan rata-rata elemen struktur kolom dengan menggunakan metode HT berkisar 245 kg/cm2 dan menggunakan metode UPV berkisar 283 kg/cm2. Untuk prediksi kuat tekan rata-rata elemen struktur balok dengan menggunakan metode HT berkisar 289 kg/cm2 dan menggunakan metode UPV berkisar 339 kg/cm2. Sedangkan untuk prediksi kuat tekan rata-rata elemen struktur pelat dengan menggunakan metode HT berkisar 170 kg/cm2 dan menggunakan metode UPV berkisar 244 kg/cm2. Hasil pengujian kualitas mutu elemen struktur bangunan gedung yang diperoleh ini masih memenuhi syarat mutu beton seperti yang direncanakan.

Abstract

The building structure can be said to be safe if supported by a strong foundation, so it is necessary to calculate the bearing capacity of the foundation using bored piles based on sondir data, calculate the load received by the pile cap, and calculate the amount of pile cap reinforcement. The method used is analytical and descriptive, while for the calculation of the foundation using the Meyerhoff method. The foundation analyzed is a bored pile foundation with a diameter of 0.4 m and a depth of 7 m. The results of the study, the type of native soil from Tomohon, North Sulawesi according to the USCS classification is soft clay with a bored pile bearing capacity of Qg = 177.45 tons. For the maximum axial force on the pile of 421.02 kN with a shear strength of 447.214 kN. The pile cap reinforcement obtained is reinforcement with a diameter of 19 mm with a distance between reinforcement of 200 mm and a used reinforcement area of ​​1134.11 mm2. The shrinkage reinforcement used is Ø12 with a distance between reinforcement of 160 mm. The substructure of a building should begin with a soil and location investigation to determine the characteristics of the soil on which a building will be built

Abstract

Difficulties in obtaining information regarding inventory stock and in generating reports for incoming and outgoing goods have become persistent challenges for companies. To address these issues, an information system that meets the company's informational needs is required. This study aims to design a web-based inventory information system. In response to these challenges, it is necessary to develop a digital inventory recording system that is easily accessible, user-friendly, and relevant to the conditions of micro, small, and medium enterprises (MSMEs). The system should be capable of automating the recording process of incoming and outgoing goods, sending notifications when stock reaches the minimum threshold, and generating reports to support inventory planning and control. Given this background, the central research question is: How can a digital inventory recording system be designed for MSMEs in Manado City? A digital-based accounting information system can assist businesses, particularly MSMEs, in presenting reliable information in an effective, efficient, affordable, and user-friendly manner. The Waterfall model is a traditional method used in information system development. This method follows a sequential and structured process, starting from requirement analysis, system design, implementation, testing, to maintenance and updates. The proposed digital inventory recording system can assist MSMEs in tracking stock accurately, efficiently, and in real time. Features such as notifications, automated reporting, and a simple interface make this system easy to use and well-suited for the needs of small businesses. Additionally, the system is designed to support future digital integration.

Abstract

An important consideration in structural calculations is a structure's vibration period, which establishes the size of the seismic stresses applied during the design phase. North Sulawesi falls within the category of high-risk earthquake region. The formula for calculating the vibration period, as outlined in SNI 03-1726-2012 is based on Goel and Chopra's (1997) approach and ASCE seismic standards. Nevertheless, SNI 03-1726-2012's formula has a notable limitation: it applies the same approach to all earthquake zones, regardless of whether the area is high-risk or low-risk. This study aims to develop a structural period formula tailored following the SNI 03-1726-2012 earthquake design guidelines and to investigate how the quality of the concrete affects the structural lifespan. Three-dimensional structural modeling of typical structures with floors is used in the study. heights of 4 meters and widths of 4 meters, specifically focusing on mid-rise reinforced concrete buildings with 12 floors. Structural modeling is conducted using the ETABS software, and regression analysis is performed on the resulting structural period values to derive the most accurate formula. The regression analysis yielded two optimal formulas, each with a correlation value of 98%: T=0.105H0.785T = 0.105 H^{0.785}T=0.105H0.785 and T=0.311n0.785T = 0.311 n^{0.785}T=0.311n0.785. The findings indicate that lower concrete quality leads to an increased structural period, albeit with a smaller overall impact. Thus, concrete quality significantly influences the structural period

Abstract

According to data from the International Labor Organization (ILO), the construction industry accounts for nearly 20% of all workplace accidents that occur worldwide. This emphasizes the importance of continued efforts to improve work safety in this sector (Artha Safety, 2024). In addition, the application of smart technology can also help improve operational efficiency, enable faster identification of risks, and enable more effective interventions before accidents occur. Therefore, this research aims to take a closer look at the role of smart technology in improving work safety in the construction environment. This research used a combination of quantitative and qualitative methods. Literature study, primary data collection, and data analysis are the three main stages of this research. From the available data, it can be seen that the adoption of smart technologies, including AI, IoT, and wearable devices, has a significant impact on reducing accidents in the construction sector. Not only a decrease in fatal accidents, but also an increase in workers' awareness of physical conditions and potential hazards on the job site. However, some challenges such as worker resistance and implementation costs still need to be overcome through education and management support. Implementing these technologies requires a comprehensive approach, including intensive training and education for workers, as well as management support to overcome resistance and implementation cost challenges. This investment in smart technology will ultimately lead to a safer, more efficient and productive work environment in the future.

Abstract

This study investigates the relationship between the use of Personal Protective Equipment (PPE) and the reduction of workplace injuries among workers at PT X. Using a quantitative research design with a pre-test and post-test survey approach, data were collected from 110 respondents selected through purposive sampling. The results demonstrated a significant decrease in workplace injuries after the implementation of PPE, with the average injury score dropping from 2.27 before PPE use to 1.50 after PPE use (p-value = 0.000). These findings indicate that the use of PPE is highly effective in reducing both the frequency and severity of workplace injuries. Factors such as worker discipline, awareness, and knowledge significantly influence the effectiveness of PPE use. The study concludes that consistent and proper use of PPE, supported by worker education and the availability of quality equipment, can substantially enhance workplace safety and reduce occupational health risks.
