<![CDATA[Acid fracturing is one of the well stimulation methods that aims to restore or even increase the decline in well productivity caused by several factors, such as unstable production rates by giving a new way (bypass) to hydrocarbons. The NJT-25 well in the Subang Field is a well that was stimulated using acid fracturing on Friday, October 25, 2024. The NJT-25 well has a low permeability of Limestone rock mineralogy of about 2.2 mD with a porosity value of 12%. The mixing fluid used is Water Base Fluid, which is the water-based and acid-based mixing fluid used is 15% Hcl. The process of implementing acid fracturing begins with a step rate test, and immediately plays frac. The reason for acid fracturing in the NJT-25 well is that water injection wells as water disposal are less effective when injected with water because of the small rate of water injection, which is with a value of 365.49 BWPD. After acid fracturing, the NJT-25 well experienced an increase in permeability value of around 572.51 mD with an average permeability of around 9.2 mD followed by an increase in the productivity index (PI) with the Prats method of around 3.1 times and the Cinco-Ley method of around 3.3 times. The rate of water injection in the NJT-25 well is 1511.59 BWPD.]]>

<![CDATA[Healthcare workers’ compliance with National Quality Indicators plays an important role in maintaining healthcare quality and patient safety. This study aimed to analyze healthcare workers’ compliance and identify the most dominant associated factor in the inpatient units of Dr. H. Mohamad Rabain Regional General Hospital. This quantitative study used a cross-sectional design and involved 80 nurses and midwives selected through proportionate stratified random sampling. The researchers collected data using structured questionnaires and a direct observation checklist that assessed hand hygiene, personal protective equipment use, patient identification, and fall-risk prevention. The researchers analyzed the data using descriptive analysis, the Chi-square test, and multiple logistic regression. The results showed that most healthcare workers complied with the National Quality Indicators. Age, sex, educational level, knowledge, attitude, length of service, supervision, workload, training, and facilities and infrastructure were significantly associated with compliance. Knowledge, attitude, training, and facilities and infrastructure remained significant in the adjusted model. Facilities and infrastructure represented the most dominant factor associated with healthcare workers’ compliance. Hospital management should ensure the availability of adequate facilities and strengthen continuous training, supervision, competency development, and compliance monitoring to improve quality implementation and patient safety.]]>

<![CDATA[Elderly individuals are prone to a decline in walking ability, which is commonly indicated by reduced gait walking speed and may increase the risk of falls. Gait walking speed is an important parameter in gait analysis as it reflects functional mobility, balance, and lower extremity muscle strength in older adults. One exercise program recommended to improve walking ability and reduce fall risk is the Otago Exercise Program. This study aimed to determine the effect of the Otago Exercise Program on improving gait walking speed in elderly women with a risk of falling at Posyandu Harapan Bunda. This study employed a pre-experimental design using a one-group pretest–posttest approach. The sample consisted of 52 elderly women aged 60–69 years with a risk of falling, selected using total sampling. The Otago Exercise Program was conducted for 8 weeks with a frequency of three sessions per week (12 sessions). Gait walking speed was measured using the 10 Meter Walking Test (10MWT) before and after the intervention. Data were analyzed descriptively and inferentially using the Wilcoxon test. The results showed an improvement in gait walking speed after the Otago Exercise intervention. The mean 10MWT score increased from 65.55 before the intervention to 95.22 after the intervention. The Wilcoxon test results indicated a significant effect of the Otago Exercise Program on improving gait walking speed in elderly women with a risk of falling (p < 0.05). In conclusion, the Otago Exercise Program has a significant effect on improving gait walking speed in elderly women with a risk of falling. This exercise program can be recommended as an effective intervention to enhance walking ability and reduce fall risk in the elderly population.]]>

<![CDATA[The development of the Dumai and Selinsing industrial areas has led to an increase in freight traffic, impacting the performance of roads serving logistics distribution activities. The high volume of heavy vehicles on Jalan Arifin Ahmad has the potential to reduce the level of road service, necessitating an evaluation of the planned rerouting of freight transport to Jalan Abdul Naim as an alternative route. The research methods used were traffic surveys, vehicle speed surveys, road geometric data collection, and road performance analysis based on the 2023 Indonesian Road Capacity Guidelines (PKJI). The parameters analyzed included traffic volume, road capacity, degree of saturation (DJ), free flow speed, travel time, and level of service (Level of Service/LOS). The analysis was conducted on existing conditions, after the rerouting, and projected traffic growth for the 5- and 10-year periods. The research results show that under existing conditions, Jalan Arifin Ahmad has a capacity of 2,318 SMP/hour, a traffic volume of 679 SMP/hour, and a saturation level of 0.29 with a service level of B. After heavy vehicles were transferred to the alternative route, traffic volume decreased to 637 SMP/hour with a saturation level of 0.27, remaining at LOS B. In the 5th year projection, the saturation level increased to 0.53 (LOS C) and in the 10th year to 0.64 (LOS C). Meanwhile, Jalan Abdul Naim, as an alternative route, demonstrated excellent performance with a saturation level ranging from 0.16–0.24 and a service level of A–B. The research results indicate that the rerouting of freight transport can reduce traffic load on Jalan Arifin Ahmad without reducing the performance of Jalan Abdul Naim, making this alternative route suitable for supporting smooth distribution to the Dumai and Selinsing industrial areas]]>

<![CDATA[The increasing elderly population in Indonesia has led to various health problems, particularly related to nutritional status and physical activity. Body Mass Index (BMI) is a simple indicator used to assess nutritional status, while physical activity plays an important role in maintaining energy balance and body composition. Elderly individuals with low levels of physical activity are at greater risk of having abnormal BMI, which may lead to degenerative diseases. This study used an analytic design with a cross-sectional approach. The research sample consisted of 109 elderly individuals at Posyandu Lansia Harapan Bunda who met the inclusion criteria. Body Mass Index (BMI) was measured by assessing body weight and height and calculated using the BMI formula (kg/m²), while physical activity levels were assessed using the Physical Activity Scale for the Elderly (PASE) questionnaire. Data were analyzed using univariate and bivariate analyses. The Spearman correlation test was applied with a significance level of p < 0.05 to determine the relationship between BMI and physical activity. The findings showed a significant relationship between body mass index and physical activity among the elderly. Elderly individuals with low physical activity levels tended to have overweight and obesity categories of BMI, while those with moderate to high physical activity tended to have normal BMI. There is a relationship between body mass index and physical activity among the elderly at Posyandu Lansia Harapan Bunda. Higher levels of physical activity contribute to maintaining BMI within the normal range.]]>

<![CDATA[The construction of high-rise buildings requires effective scheduling methods to ensure project completion according to time, cost, and quality targets. This study aims to analyze the effectiveness of the Line of Balance (LOB) method compared with the Bar Chart method in scheduling structural work on the UNIPI Bandung Campus Building Construction Project. This research used a quantitative comparative method based on secondary data, including project schedules, work durations, and repetitive structural activities such as columns, beams, slabs, and stairs. The analysis was conducted by developing LOB schedules using average and minimum lag times, followed by a comparison of project duration and time efficiency. The results showed that the LOB method using minimum lag time produced the shortest duration, reducing the project completion time from 24 weeks to 20 weeks with a time efficiency of 16.67%. The total project cost remained unchanged, but the weekly cost distribution differed due to accelerated work progress. The LOB method is effective for optimizing repetitive construction scheduling and improving workflow continuity.]]>

<![CDATA[Cervical cancer is the fourth most common cancer among women, with resistance to therapy often linked to Bcl-2 overexpression. This study evaluated the anticancer activity of durian peel extract (Durio zibethinus Murray) against HeLa cells through Bcl-2-mediated apoptosis and investigated apigenin and luteolin interactions with Bcl-2 via molecular docking. The extract was prepared by ethanol maceration, characterized by phytochemical screening and GC-MS, and tested for cytotoxicity using the MTT assay, while apoptosis was assessed through Bcl-2 immunofluorescence. Phytochemical screening confirmed flavonoids, alkaloids, saponins, tannins, and triterpenoids, with GC-MS identifying over 93 bioactive compounds. The extract exhibited significant cytotoxicity with an IC₅₀ of 5.92 μg/mL, and cell viability decreased concentration-dependently (p < 0.05), accompanied by apoptotic morphological changes and reduced Bcl-2 expression. Molecular docking revealed favorable binding of apigenin and luteolin to Bcl-2, with binding energies of −6.01 and −5.55 kcal/mol, respectively. In conclusion, durian peel extract demonstrates promising anticancer activity against HeLa cells by inducing apoptosis through Bcl-2 suppression, with apigenin and luteolin serving as potential natural candidates for cervical cancer therapy.]]>

<![CDATA[Vaccine cold chain management is an essential component in ensuring vaccine quality, safety, and effectiveness until administration in immunization services. Primary health care centers play a strategic role in cold chain implementation; however, various studies report persistent challenges related to storage, temperature monitoring, distribution, and human resource capacity. This article aims to comprehensively review vaccine cold chain management in primary health care centers by integrating national and international scientific evidence and pharmaceutical management perspectives. A narrative literature review was conducted using national and international databases, including articles published between 2020 and 2025 Of the 50 international and 25 national articles identified, screening based on titles, abstracts, and full-text assessment resulted in 14 relevant articles for analysis. The findings indicate that although most primary health care centers have implemented basic cold chain principles, significant gaps remain in temperature monitoring consistency, distribution documentation, utilization of supporting facilities, and pharmacist involvement in vaccine quality assurance systems. Strengthening the role of pharmacists, supported by temperature monitoring technology and adherence to national guidelines, is a key strategy to improve vaccine management quality in primary health care centers]]>
