Abstract

Penelitian ini membahas rancang bangun dan pengembangan sistem penjadwalan sholat digital berbasis Internet of Things (IoT) untuk meningkatkan keandalan dan fleksibilitas sistem yang telah digunakan sebelumnya. Sistem lama yang dibangun menggunakan Arduino Mega2560, RTC DS1307 dan panel 7-segment dengan driver ULN2003 memiliki keterbatasan, yaitu tidak tersedianya sinkronisasi waktu otomatis serta pengaturan jeda iqomah yang masih dilakukan secara manual. Dalam penelitian ini, pengembangan dilakukan dengan menambahkan modul ESP32 yang terhubung ke jaringan Wi-Fi untuk melakukan sinkronisasi waktu secara otomatis melalui server Network Time Protocol (NTP). Modul ini juga menyediakan antarmuka berbasis web yang dapat diakses melalui smartphone, sehingga pengaturan jadwal dan jeda iqomah menjadi lebih fleksibel. Komunikasi data antara ESP32 dan Arduino Mega2560 dilakukan melalui protokol Universal Asynchronous Receiver Transmitter (UART) yang terbukti stabil selama pengujian. Hasil pengujian menunjukkan bahwa sistem mampu menjaga deviasi waktu di bawah satu detik dan pengaturan jadwal melalui antarmuka web dapat dilakukan dalam waktu kurang dari dua detik. Sistem ini dinilai lebih andal, efisien, dan sesuai dengan kebutuhan operasional masjid modern, serta mampu menggantikan sistem lama yang kurang fleksibel dalam pengelolaan waktu ibadah.

Abstract

Brick is one of the materials used in building house walls. The demand for red bricks in construction and business growth in the property sector is increasing. Lubuk Alung District, precisely in Jorong, Kampung Ladang, is one of the West Sumatra areas producing conventional bricks. The process of firing brick in this sub-district is still carried out using a conventional furnace, using wood as an energy source. The quality of the red bricks produced is different due to the different positions of the bricks in the kiln. This research aims to determine whether the red bricks produced in Jorong Kampung Ladang, Lubuk Alung District, meet the quality classification of red bricks according to SNI 15-2094-2000. From the results, the bricks in the upper, middle, and lower firing positions meet the quality requirements for the physical properties of red bricks. However, red bricks in the upper, middle, and lower firing positions do not meet the SNI 15-2094-2000 quality standards regarding dimensions or sizes. Meanwhile, the results of mechanical properties testing for specific gravity and compressive strength showed that none of the test object samples met the standards required according to SNI 15-2094-2000.

Abstract

The high number of work accidents in Indonesia shows that there are still many workers who ignore the issue of Health, Safety, and Environment (HSE) and its implementation procedures because they prefer to work based on experience. In the implementation of the Muaro Mais - LubukGobing Bridge Construction Project, it is necessary to apply HSE in the project environment because of environmental factors that are at risk of causing work accidents such as high rain intensity, the use of heavy equipment, and river flow that can change at any time so that it can be risky for the implementation time of the project. To reduce the rate of work accidents, it is necessary to have a safety system and work health system to create safety and workhealth systems for workers with It is hoped that the construction project can proceed on time. This study aims to determine the effect of the application of HSE on the Muaro Mais – LubukGobing Bridge Construction Project, West Pasaman Regency on the project implementation time by analyzing data using SmartPLS software version 3.2. This research was conducted by distributing questionnaires to workers on bridge construction projects. The results of this study show the Leadership and Administration Indicators of construction service providers (X1) on Punctuality (Y) with a p-value of 0.28 1 > 0.05, a t-statistic value of 1.079 < 1.96, and an original sample O = 0.272. Work Safety Inspection Indicator (X2) against the variable Punctuality (Y) with a p-value of 0.677 > 0.05, t-statistic 0.416 < 1.96, and original sample O = 0.143.

Abstract

Antenatal care (ANC) refers to the care provided to mothers and their unborn babies during pregnancy. ANC visits are essential, as they allow for the early provision of important information and education regarding pregnancy and childbirth preparation. Objective to identify the factors influencing pregnant women's compliance with the minimum standard pregnancy examinations in the Deli Serdang District Health Office, North Sumatra. This study used a quantitative and cross-sectional approach, involving 138 pregnant using puposive sampling women from four community health centers under the Deli Serdang District Health Office, North Sumatra, Indonesia. Data were collected using questionnaires and analyzed using the McNemar, Chi-square, and multiple logistic regression tests The results of the study showed that factors influencing compliance with the minimum standard pregnancy examinations included the mother's last education level, gestational age, transportation, travel time, ANC visit frequency, media exposure, knowledge, and attitude, with a p-value of 0.000 < 0.05. The most dominant factor affecting compliance with ANC visits was the type of transportation used (p-value = 0.039). Education level, gestational age, transportation, travel time, ANC visit frequency, media exposure, knowledge, and attitude all influence compliance with ANC. Pregnant women should improve their attitude and motivation to seek information about healthy pregnancy using easier access, such as e-books or web links that can be read anytime and anywhere. In today's digital era, this can help increase awareness and knowledge about the importance of ANC, ultimately improving ANC coverage (K1-K4) and reducing maternal mortality rates.

Abstract

Reinforced concrete is a construction that is vulnerable to damage during an earthquake if not done properly. This article focuses on the results of field observations after the earthquake disaster in Lombok and Palu in 2018, with the aim of identifying the type of damage that occurred in reinforced concrete buildings. This identification is important to understand the potential causes of damage and/or collapse in reinforced concrete buildings. The results of field observations show that low concrete quality and lack of standard reinforcement detailing processes are the main factors contributing to the large number of buildings experiencing damage and/or collapse during the earthquake. Poor quality concrete, such as a mismatch in the mix or a lack of strength, can make a structure brittle and unable to withstand excessive earthquake forces. Apart from that, lack of attention to the reinforcement detailing process is also a cause of significant damage. Non-standard reinforcement detailing includes a lack of the required amount of reinforcement in the structure, installation of shear reinforcement that does not meet the requirements, and a lack of shear reinforcement at beam and column connections. Lack of reinforcement in structural connections reduces the strength and stiffness of the structural system, thereby increasing the risk of collapse during an earthquake. The location and method of installing brick walls is also one of the factors causing building damage. Through analysis of the results of these observations, it can be concluded that good quality concrete and the process of detailing reinforcement and brick walls according to standards are very important to reduce damage and increase the resistance of reinforced concrete structures to earthquakes. Proper implementation of structural design specifications and careful monitoring during construction can help reduce the risk of damage caused by earthquakes.

Abstract

In today's rapidly evolving industrial landscape, businesses are increasingly challenged to strike a balance between enhancing productivity and maintaining product quality. Company X, a renowned cement manufacturer in Indonesia, relies heavily on four key raw materials, among which clay is particularly crucial for the raw mix. Recent trends have shown a decrease in the Al2O3 composition of clay, necessitating adjustments in clay capacity to uphold quality standards. A thorough technical evaluation of the plant highlighted that a significant number of critical machines, totaling 17, were operating with mechanical availability below the desired threshold. Additionally, a utility analysis pinpointed a shortfall in meeting the required clay tonnage, leading to the identification of machines that would benefit from retrofitting. The financial implications of this initiative were substantial, with the initial investment for the upgrades and subsequent operational costs in the first year being considerable. Yet, this expenditure was offset by a notable profit in the first year post-retrofitting. Key financial metrics further underscored the project's viability: a highly favorable Net Present Value (NPV), an impressive Internal Rate of Return (IRR), a rapid Payback Period (PP), and a significant Profitability Index (PI). These parameters, derived from an exhaustive analysis, clearly support the strategic decision to invest in retrofitting the production machinery at Company X's cement plant, illustrating the project's feasibility and the prospective benefits of this investment.

Abstract

Insider threats become one of the most dangerous threats in the cyber world as compared to outsider as the insiders have knowledge of assets. In addition, the threats itself considered in-visible and no one can predict what, when and how exactly the threat launched. Based on conducting literature, threat in Automated Manufacturing Execution Systems (AMESs) can be divided into three principle factors. Moreover, there is no standard framework to be referring which exist nowadays to categorize such factors in order to identify insider threats possible features. Therefore, from the conducted literature a standard theoretical categorization of insider threats framework for AMESs has been proposed. Hence, three principle factors, i.e. Human, Systems and Machine have considered as major categorization of insider threats. Consequently, the possible features for each factor identified based on previous researcher recommendations. Therefore, via identifying possible features and categorize it into principle factors or groups, a standard framework could be derived. These frameworks will contribute more benefit specifically in the manufacturing field as a reference to mitigate an insider threat. Keywords—automated manufacturing execution systems insider threats, factors and features, insider threat categorization framework.
