Splitting Tensile Strength Analysis of High-Strength Concrete Using Ureolytic Bacteria from Local Landfill as Microbial Self-Healing

High-strength concrete is a brittle material due to its low tensile strength. Splitting tensile strength of concrete can be used to determine the concrete tensile capacity. High-strength concrete has high bearing capacity and good durability during its service life but excessive loads and extreme environmental influences can reduce its strength, thus, early maintenance is needed. Efforts that can be made are applying self-healing concrete using ureolytic bacteria obtained from local landfill Gampong Jawa, Banda Aceh, namely Bacillus sp. Splitting tensile strength test of concrete was carried out using cylindrical specimen with diameter 15 cm and height 30 cm. Bacillus sp. bacteria can produce calcium carbonate (CaCO3) as concrete crack-healing with the help of precursors, i.e., urea and Ca2+ ion along with nutrient broth as their nutrients. To ensure better bacterial viability, the bacteria along with their precursors and nutrients were encapsulated with diatomaceous earth and then coated with cement paste. Variations used are the concentration of bacteria along with their precursors and nutrients, i.e., 1.27%, 1.53%, and 1.79% from cement weight. To activate the CaCO3 formation by bacteria, the specimens were cracked first with a load of approximately 40% of its splitting tensile strength after being soaked in water for 7 days, then soaked again in water for 28 days for crack-healing before being tested. Splitting tensile strength analysis showed that the higher the concentration of Bacillus sp. bacteria, the greater the difference of splitting tensile strength between initial cracking load and after self-healing treatment, which indicates better crack-healing efficacy.

The Analysis of Service Level on Diponegoro Road, Pasar Aceh: Comparing The Existing Condition and with on-Street Parking Restriction

Traffic congestion is a major problem in cities, especially on the main roads in the Central Business District (CBD) area, as occurred on Diponegoro Road in Banda Aceh, Indonesia. This problem has economic, social, and environmental impacts, such as fuel wastage, longer travel times, and air pollution from vehicle exhaust gases. Factors causing traffic congestion include side friction, such as road crossings (Pedestrian/PED), parking and stop vehicles (PSV), entry and exit vehicles (EEV), and slowmoving vehicles (SMV). Diponegoro Road is a three-lane one-way road (3/1 TT). However, only one lane is effective during peak hours, while the other is used for vehicle parking. Therefore, this study aims to analyze the service level of Dipenogoro Road under existing conditions and with the implementation of on-street parking restrictions. The road performance was calculated using the Indonesian Road Capacity Guidelines (PKJI) 2023 method. The data needed are traffic volume, road geometrics, side friction, and population. The study results show that the road's service level on weekdays (Monday and Thursday) is on level C, indicating that traffic conditions limit the speed and movement of vehicles, and the drivers are restricted in choosing the desired speed. On Sunday mornings, the road level of service is on level B, while in the afternoon, it becomes level D. This difference in service level occurs because there is no activity to access schools or workplaces on Sunday mornings. On Sunday afternoons, most citizens go shopping or sightseeing, causing volume and roadside friction to increase and road performance to drop. The level of road service with the implementation of on-street parking restrictions shows a good level (A and B), with an indication of stable traffic flow, and drivers are free to choose their driving speed. Thus, this research recommends maximizing off-street parking to limit on-street parking.

THE INFLUENCE OF ORGANIZATIONAL CULTURE AND CAREER DEVELOPMENT ON JUDICIAL APPARATUS PERFORMANCE MEDIATED BY LEADERSHIP STYLE : STUDY ON THE MILITARY COURTS OF REGION I & II INDONESIA

This study aims to examine the influence of organizational culture and career development on judicial apparatus performance which is mediated by leadership style. The population was all judicial apparatus at the Military Court Region I & II Indonesia, consisting of Military Court I-01 Banda Aceh, Military Court I-02 Medan, Military Court I-08 Jakarta, and Military Court II-10 Semarang, totaling 167 people. Research sampling was conducted using the census method where the entire population became research respondents. The analysis tools used are SPSS, SEM AMOS, and Sobel Calculator. The results of descriptive testing prove that the organizational culture, career development, leadership style, and performance of the judicial apparatus are good. The results of direct effect hypothesis testing prove that organizational culture positively and significantly affects leadership style, but career development does not affect leadership style. Furthermore, organizational culture, career development, and leadership style positively and significantly affect judicial apparatus performance. Additionally, the results of indirect effect hypothesis testing prove that leadership style (partially) mediates the organizational culture impact on judicial apparatus performance, but leadership style does not mediate the career development impact on judicial apparatus performance.

Multiple Regression Analysis to The Influence of Communication Management on Project Success

The success of a construction project, in general, is known to have a triple constraint with the criteria of being on time, on cost, and quality. Project success is highly dependent on effective communication as it can increase project success by up to 80% compared to poor communication by only 52%. Several studies have found that poor communication is one of the most critical obstacles to construction project success. The purpose of this study is to analyze the relationship between communication management (X) and the success of construction projects (Y) simultaneously. The sample for this study was obtained using a total sampling technique so that the sample size corresponds to the members of the population, namely as many as 30 construction companies registered with the Association of National Construction Executors (GAPENSI) in Banda Aceh, one of the provinces in Indonesia. Based on the analysis results, it was found that communication management simultaneously had an influence of 53.2% on the success of construction projects. In comparison, the other 46.8% was determined by variables not examined in this study.

Prevalence of extended spectrum beta-lactamase (ESBL) Escherichia coli recovered from ICU and non-ICU at dr. Zainoel Abidin General Hospital

Research conducted at Zainoel Abidin General Hospital in Banda Aceh between January 2022 and July 2023, focused on the prevalence and susceptibility patterns of extended-spectrum beta-lactamases (ESBL)-producing Escherichia coli associated with nosocomial infections. This study employed a retrospective descriptive methodology to analyze clinical specimens from both the intensive care unit (ICU) and non-ICU settings. Of the 520 isolates examined, 365 (70.19%) were identified as ESBL-producing Escherichia coli. The age group of 56-65 had the highest prevalence (28.21%), with female patients contributing 52.50% of the isolates. Both ESBL-producing and non-ESBL-producing E. coli had almost equivalent prevalence among patients treated in the ICU and non-ICU, accounting for 67%. Antibiotic susceptibility testing revealed high levels of resistance to carbapenem. Conversely, polymyxin B showed complete susceptibility (100%) and cefoxitin exhibited an 85% susceptibility rate. These findings underscore the alarm resistance levels of ESBL-producing Escherichia coli isolates.

Anxiety and diet among elderly people suffering from diabetes mellitus in Banda Aceh, Indonesia: A correlational study

Successfully managing diabetes over a long period is challenging and requires close monitoring of one’s diet and lifestyle. However, mental health issues such as anxiety can make it difficult to manage diabetes effectively, especially in older people. This study aims to highlight the psychological challenges older people with diabetes face, emphasizing the importance of mental health in managing chronic illnesses. It explores how anxiety affects the eating habits of older individuals with diabetes. The study used a quantitative method and a descriptive correlational research design. It involved older people with diabetes mellitus, with about 300 participants selected through purposive sampling based on certain criteria. The study measured anxiety levels using the GAS questionnaire, which is highly reliable (0.93), and dietary patterns were assessed with the UK-DDQ, which has a reliability of 0.765. The findings show that most participants were female (62%), in their early elderly years (89.7%), and had finished high school (67.7%). Regarding income, 39.3% earned less than Rp. 1,500,000. Over half lived with a partner (51%) and felt sadness and depression (64%). A minority had no family history of diabetes (38.3%), and most were cared for by their children (54.3%). Most participants had been living with diabetes for 2-5 years (54.1%) and did not smoke (85%). In terms of treatment, the majority used metformin (73.7%), and just over half did not use traditional medicine (51.3%). The study found a significant link between anxiety and diet in older adults with diabetes mellitus, with a p-value of 0.006 (alpha = 0.05). It suggests that healthcare providers should consider the whole well-being of older adults with diabetes, recognizing that anxiety can hinder their ability to follow a diet plan. Therefore, it is crucial to understand a patient’s mental, emotional, and physical health for effective treatment.

Base saturation flow rate (BSFR) and its effect on performance of pretimed signalized intersection with non-lane based urban heterogeneous traffic.

Signalized intersections that are pretimed are commonly used in rapidly developing cities with diverse traffic patterns, including those found in Indonesia. These intersections are a common source of congestion and delays in road networks, particularly when there is non-lane based (NLB) traffic in urban areas. Accurate estimation of both the base saturation flow rate and capacity is essential for this type of facility, as an error in the prediction of the base saturation flow rate can result in significant bias in capacity evaluation and design at signalized intersections. The estimation of capacity at signalized intersections is critical for ensuring optimal signal timings, minimizing delay, and reducing congestion. Heterogeneous traffic, which refers to the presence of various types of vehicles with distinct static and dynamic characteristics, is a common phenomenon. To address this issue, this paper presents a modeling approach for the SFR that takes into account heterogeneous traffic and NLB movements. Indonesia, being an archipelago with 34 provinces, served as the focus of this study, which specifically concentrated on Banda Aceh, the capital province of Aceh province. Employing primary and observed data collected at a specific, predetermined signalized timing, this study aimed to investigate the impact of intersection geometry and heterogeneous traffic composition on the SFR. By adopting the modeling approach for NLB movements, the study formulated the BSFR model. To estimate the scale parameters of the BSFR, the multiple linear regression approach was utilized. The analysis results reveal that the existing BSFR based on the IHCM formula gives a substantially biased estimation because the PCEs from the Indonesian Highway Capacity Manual (IHCM) are underestimated. This source of error could be partially due to the heterogeneous (varied vehicle composition) traffic flow with NLB movements, unlike that observed under the prevailing conditions of IHCM 1997. The empirical results show that the existing IHCM should be improved to avoid overestimation, particularly for effective approach width (We) greater than 4.5 m. A comparison of the BSFR prediction model between IHCM's PCEs and new PCEs shows that the BSFR is predicted more accurately in the latter case. This finding demonstrates that the existing IHCM can be adjusted in two ways: adjusting PCEs or calibrating the BSFR formula. The proposed models can also enhance the accuracy of BSFR prediction, leading to better signalized intersection capacity estimation, providing support for designing traffic operation, alleviating traffic congestion, and reducing congestion delay within the city.

A story of entanglement between Indonesian national heroes, museums, and decolonization

Sultan Hasanuddin of South Sulawesi (1631-1670), Javanese Prince Diponegoro (1785-1855), and Teuku Umar of Aceh (1854-1899) were all acknowledged in 1973 by the Indonesian government as National Heroes for their resistance against the Dutch colonial power. This article discusses how their stories and belongings – exhibited in museums – intertwine with museum decolonization. The focus of this article relies on research in province museums in Makassar, Jakarta, and Banda Aceh. They were all established in colonial times and are all in some way related to the three heroes. These examples show how the decolonization of Indonesian museums is entangled with changing political regimes.

Food Inflation and Household Welfare: A Qualitative Study in The City of Banda Aceh

The results of this study, which was conducted using a field survey (observation) and interviews over seven days in November 2023, showed that food inflation had a negative impact on household welfare in Banda Aceh City. The increase in food prices affects household expenditure, consumption, and health. In dealing with food inflation, households are advised to grow vegetables by utilizing the narrow land around the house to meet some of their food needs. The government is expected to implement policies to avoid food price increases. So that household welfare becomes better with increased purchasing power. These findings suggest practical solutions for households and the government to mitigate the negative effects of food inflation. It is also suggested that future research can be conducted in more depth by comparing Banda Aceh City and other districts in Aceh Province.

Factors Influencing Traffic Accidents Involvement: A Case Study of Online Motorcycle Taxi Drivers in Banda Aceh

In Indonesia, online transportation or motorcycle taxi is often used because they can take passengers to their destination at an affordable cost. Still, along with the rise of online motorcycle taxi facilities that are not balanced with safety facilities, human factors significantly influence traffic accidents. This study aims to identify personal characteristics and driver behavior related to anxiety, aggressive driving, impatience, and violations of accident involvement in Banda Aceh city. Data collection in this study was carried out by distributing questionnaires using Google Forms aimed at online transportation drivers, as many as 200 respondents, to determine the characteristics and driving behavior. Structural Equation Modeling (SEM) method with Confirmatory Factor Analysis (CFA) model to analyze the relationship between driving behavior variables on accident involvement in Banda Aceh city. The results of respondents’ perceptions of unsafe driving behavior towards traffic accident involvement show that all indicators have a value above 2.5 on a Likert scale of 1-4. The results of CFA modeling showed that the relationship between variables Anxiety, aggressive driving, and impatience has a positive correlation value with a significant effect on accident involvement. From the modeling, the most significant indicator is the indicator “Taking the opportunity and accelerating the speed of the vehicle when the yellow light before turning red?” with a t-value of 6.996, while the impatience variable is “Feeling impatient or angry at slow drivers and wanting to get ahead of them?” with a t-value of 6.592 and “Feeling worried if you suddenly feel sleepy while driving” with a t-value of 3.598. Based on the results, it can be stated that impatience and aggressive driving lead to accident involvement.

Microplastic characteristics in several land covers in Banda Aceh and Aceh Besar

Plastic is one of the materials that is often used by people who are difficult to decompose. The decomposed plastic will become several parts which are termed macro plastic and micro plastic. Plastic will accumulate in soil and water can release chemicals that will endanger plant health. The purpose of this paper is to identify the accumulation of microplastics in several land covers. The research started with sampling on land cover at Mini Sport center Universitas Syiah Kuala (Gelanggang Park), Experimental Farm of Faculty of Agriculture, Urban Forest, Community Park (Tahura), and Edge of cross road (sibreh). Each replicate was sampled amount to 30 top soil samples (0-5 cm) and 30 subsoil samples (5-20 cm). Total soil samples per location point were 6 samples. The stages carried out were starting from drying the sample, separating the sediment, removing the organic material, separating the solid and identifying microplastic. Results found that the most dominant type of microplastics found at each sample point is the Fragment type of microplastics with 164 particles. Then fiber type microplastics with a particle count of 103 particles. While the least found is the type of microplastic film with a particle count of 92 particles. At Gelanggang Park, we found a high abundance of Film species and a moderate abundance of Fiber species. The Urban Forest had a low abundance of all particle types. The most common colour appearing in the data are Brown and Grey, with a total of 210 and 73 respectively. The colours dominate compared to other colour across locations and layers, there are differences in the number of colours between the Lower and Upper layers at each site.

The Potential Causes of Contractual Change Orders Sourced from The Construction Phase of The Building Project

The process of implementing construction projects often encounters changes. One of these changes is the change order. After recognizing its existence, the change is formalized by the issuance of a change order, which is a document that describes the scope of the change and its impact on project performance. If agreement is not reached between project participants on the changes, it becomes a claim or dispute that can negatively affect project implementation and reduce the chances of project success. Changes in construction projects are frequent and can occur from many different sources, for many different reasons, at any phase of the project and can have far-reaching impacts. This study aims to identify the factors that cause Contractual Change Order (CCO) to arise during the construction phase of building projects in Banda Aceh. This study uses a quantitative method with data collection techniques through distributing questionnaires to 36 contractor companies in Banda Aceh City. Data testing was done with validity and reliability tests, while the data analysis used was descriptive. From the research results, 16 CCO factors were identified during the construction project implementation phase. It was determined the two main causes of change orders from the contractors` view are bad weather conditions and soil conditions.

Likewise, the influence of satisfaction and customer relationship management also increases repurchase intention and partially mediates the relationship between the marketing mix and consumers' repurchase intention.

Risk Factors associated with Stress-related Riding Behavior among Indonesian Motorcyclists

The risk of road accidents is influenced by various elements, particularly human factor. In Indonesia, motorcycles contribute significantly to accidents due to insufficient knowledge of traffic laws and a lack of awareness about safe riding practices. Stress-related riding behavior, which may lead to this incident, is closely linked to driving discipline. Therefore, this study aimed to examine stress-related behavior as the risk factor in road accidents among motorcyclists. To achieve this, a self-reported questionnaire was distributed to 300 motorcyclists in Banda Aceh City and surrounding areas in Aceh Province. Factor analysis was used to simplify the number of indicators included, after which they were prioritized in order of importance. The results showed the most influential indicators out of the 26 considered in this study. A total of 3 underlying factor were identified, comprising anxious riding, aggressive riding, and anger. By addressing the risk factor associated with stress-related riding behavior, road safety in Indonesia was enhanced.

A preliminary analysis of base saturation flow rate during first loss time and saturated time at pretimed signalized intersections

Saturation flow rate is a key parameter essential for assessing signalized intersection capacity. The reference often used for signalized intersection planning in Indonesia is Indonesian Highway Capacity Guidelines (PKJI, 2023). In heterogeneous traffic environments, it has been observed that driver characteristics and behaviors exhibit significant variations. Therefore, this study aimed to investigate the prevailing saturation flow rate conditions at signalized intersections within Banda Aceh City. This exploration unfolded through two distinct scenarios, namely saturated time with and without initial lost time. For data acquisition, the focus was set on four signalized intersections, namely Jambo Tape, Pocut Baren, AMD Batoh, and Lhong Raya. This extraction procedure aimed to uncover insights into vehicle composition, movement patterns, and field saturation flow rate at these signalized intersections. In the aspect of analysis, a simple linear regression approach was adopted to recalibrate saturation flow rate coefficient of signalized intersections. This recalibration took into account vehicle compositions at the observation locations. The culmination of this analysis showed that in the scenario devoid of lost time under prevailing conditions, flow rate yielded S0 = 352 x Le. Meanwhile, for the scenario entailing lost time, the calculation produced was S0 = 294 x Le.
