Magelang City faces the challenge of limited land availability, with a total area of only 18.58 km2 and a high population density. Consequently, telecommunications infrastructure development requires a precise strategy. This study aims to analyze the business model and investment feasibility of Pole and Greenfield type telecommunication towers in Magelang City. Using a descriptive quantitative approach, this research processes secondary data from PT Dayamitra Telekomunikasi Indonesia by applying feasibility analysis based on Life Cycle Costing (LCC), Net Present Value (NPV), Internal Rate of Return (IRR), Break-Even Point (BEP), Payback Period (PP), and Benefit-Cost Ratio (BCR). The results indicate significant differences in cost structures; Pole towers proved to be more efficient, requiring an initial capital outlay of only 28.8% of the total capital required for Greenfield towers. Greenfield towers generated an NPV of Rp13.07 billion with an IRR of 20%, while Pole towers generated an NPV of Rp2.46 billion with a higher IRR of 23%. Pole towers have proven to offer a faster return on investment and better operational cost efficiency, making them the most strategic option to support network densification and the implementation of 5G technology in urban areas with spatial constraints like Magelang City.

Coal hauling activities are an important part of mining operation because they affect production continuity, cycle time efficiency, and operational safety. This study aims to analyze the requirements of road support equipment on the coal hauling road from Sector 4 to the new Coal Processing Plant (CPP) at PT. Asmin Bara Bronang, Central Kalimantan. Based on road geometry, traffic density, California Bearing Ratio (CBR), and Unsurfaced Road Condition Index (URCI). The research method used was applied research with a quantitative approach. Primary data ware collected through field measurements consisting of road geometri observations, traffic density observations, Dynamic Cone Penetrometer (DCP) testing to obtain CBR values, and road surface condition assessment using the URCI method. Secondary data were obtained from the company records. The results showed that the hauling road has a total length of 9.1 km with an average width of 16 m, and grade values ranging from -7.68% to 10.52%, which are still below the maximum standard of 12%. Traffic density reached 184 dump trucks/day, for coal hauling and 62 units/day for construction material transportation, indicating high traffic intensity. CBR values ranged from 7% to 100%, showing variations in subgrade bearing capacity. The URCI value ranged from 72,50 to 91.00, indicating fair to good road conditions. Based on the analysis of road conditions and maintenance area requirements, the recommended support equipment for maintaining the hauling road consists of 1 motor grader unit, 1 compactor unit, 1 bulldozer unit, and 1 water truck unit.

Typhoid fever is a febrile illness that commonly occurs in urban areas with poor sanitation. It is usually caused by the consumption of untreated water and contaminated food. Because the S. typhi bacterium can survive in water for days, contamination of surface water—such as wastewater, freshwater, and groundwater—serves as the primary cause of typhoid fever. The patient presented to the Emergency Department of Cut Meutia General Hospital with complaints of high fever for approximately 4 days prior to admission, which had worsened over the past 2 days. The fever fluctuated and was accompanied by chills. It worsened at night and was not influenced by weather or temperature. These symptoms were accompanied by vomiting every time the patient tried to eat, nausea, abdominal pain, headache, and weakness. The patient reported vomiting the contents of their meal every time they ate, leading to a loss of appetite. These symptoms began when the patient first developed a fever. The patient also experienced abdominal pain. Spontaneous bleeding was denied. On physical examination, the patient appeared weak but was alert and oriented. On neck examination, palpable enlargement of the thyroid glands was found on the right and left sides of the neck, measuring 2x2 cm, mobile, and soft. On abdominal examination, increased bowel sounds were noted. Vital signs were normal except for the patient’s febrile temperature. Laboratory tests revealed a Tubex blood test result of scale 4 and a positive dengue IgG serology result.

Hydrocephalus is defined as active distension of the brain’s ventricular system, resulting from inadequate flow of cerebrospinal fluid from its site of production to its site of absorption into the systemic circulation. Hydrocephalus can affect anyone at any age; pediatric hydrocephalus affects 1 in 1,000 live births and is the most common cause of brain surgery in young patients. Hydrocephalus is a pathological condition characterized by abnormal accumulation of cerebrospinal fluid (CSF) due to increased production, impaired flow, or reduced absorption. Ventricular enlargement occurs in response to increased CSF volume and can lead to structural damage to the brain parenchyma. This condition can be congenital or acquired. One key point in prenatal diagnosis is the differentiation between fetal hydrocephalus and non-hypertensive ventriculomegaly. The former qualifies for intrauterine treatment with good outcomes. However, the latter can result in either favorable or catastrophic outcomes due to a damaging etiology, as seen in viral infections such as Zika virus. For an accurate diagnosis, fetal MRI is performed to detect brain anomalies, in addition to fetal ultrasound (to detect common complications), karyotype testing, and TORCH testing (toxoplasma, rubella, cytomegalovirus, herpes simplex). Obstetric management of fetal hydrocephalus depends on the gestational age at diagnosis and the presence of other anomalies. Treatment options include termination of pregnancy before the fetus is viable, placement of a ventriculoamniotic shunt, cephalocentesis before delivery, and/or cesarean section.

Postpartum depression is a postpartum mental health disorder that significantly impacts maternal well-being, infant development, and family functioning. The high prevalence of postpartum depression in Indonesia is due to limited access to health services, low mental health literacy, and social stigma in the community. This indicates a significant gap between the need for maternal mental health services and the availability of existing interventions, making education a crucial component in efforts to prevent postpartum depression early. This study aims to analyze the prevention of postpartum depression in postpartum mothers through telenursing-based education and screening using the Edinburgh Postnatal Depression Scale (EPDS) in the community. A descriptive case study design was used, involving one respondent, a 25-year-old primigravida mother residing in the Bantul area. The intervention was implemented online via WhatsApp and video calls, including structured health education on postpartum psychological changes, adaptive coping strategies, and the importance of social support. The intervention also included daily remote monitoring of the respondent's condition via the WhatsApp mobile application. The EPDS was administered as a pre-test and post-test to evaluate changes in the respondent's psychological condition. The findings showed a significant decrease in the EPDS score from 16 (moderate depression) to 6 (minimal depression), indicating significant psychological improvement. These results imply that integrating EPDS screening, structured health education, and daily monitoring is an effective and accessible community-based approach to preventing postpartum depression, particularly for mothers with limited mobility and access to health services.

Sign language recognition is one of the areas of image recognition and image processing technology that is developing rapidly in human-computer interaction. This technology really helps the deaf and speech impaired in communicating with non-disabled people. This research aims to examine the optimization of an object tracking system in sign language using the Gaussian Mixture Model (GMM) and Kalman Filter by including the Region of Interest (ROI). The proposed system consists of three main components, namely hand detection, object extraction, and classification. Hand detection is done using the Kalman Filter to track hand movements accurately. Next, Region of Interest (ROI) features, such as shape, direction and movement features, are extracted from the detected part of the hand. These features are fed into a Gaussian Mixture Model (GMM) classifier, which can recognize sign language based on the extracted features. With the combination of GMM and Kalman Filter in this research, it can increase accuracy in object tracking, reduce interference from the background, and ensure the tracking focus remains on important objects. The dataset used is in the form os SIBI alphabet symbols, namely A-Z with the amount of data for each class, namely 620 images. Based on the research result, model testing using GMM, Kalman Filter and ROI produces higher accuracy of 99%, while model testing using GMM and ROI produces accuracy of 90%.

Jakarta, the capital of Indonesia, is known for its high congestion levels. Data from the TomTom Traffic Index shows that Jakarta ranked 30th in the world in 2023 as one of the most congested cities, with a congestion level reaching 53% during peak hours. Pisangan Lama in East Jakarta is one of the densely populated areas, adjacent to busy roads. The main campus of STIKOM CKI, also located in East Jakarta, is situated along a route prone to heavy traffic. Given the congestion issues and the lack of information on the nearest routes, this study aims to implement the A* algorithm to find the shortest route from Pisangan Lama, East Jakarta, to the main campus of STIKOM CKI. The A* algorithm is chosen for its optimal routing capabilities. Based on research on three routes (Jl. I Gusti Ngurah Rai, Jl. Basuki Rachmat, and Jl. Raya Kalimalang), the results show that the route via Jl. Basuki Rachmat is the shortest, with a distance of 7.7 km. The implementation of the A* algorithm is expected to provide an efficient solution for the community in finding the nearest route.

 Background: Perineal pain due to episiotomy is a common complaint experienced by postpartum mothers and can affect patient comfort, mobility, and recovery. Nonpharmacological pain management is needed to help reduce discomfort with minimal risk of side effects. Objective: This study aimed to determine the effectiveness of applying cold compresses using ice packs in reducing perineal pain intensity in postpartum mothers with episiotomy. Methods: The study used a descriptive case study design in three vaginal postpartum patients with episiotomy who were treated in the postpartum ward. The intervention involved applying cold compresses using ice packs to the perineal area for 10–15 minutes, as per nursing procedures. Pain was measured using the Numeric Rating Scale (NRS) before and after the intervention. Findings: The results showed a decrease in pain intensity in all patients after the application of cold compresses. Patient P1 experienced a decrease in pain score from 5 to 4, patient P2 from 6 to 5, and patient P3 from 5 to 4, with an average decrease of 1 point. Implications: Cold compresses using ice packs have the potential to be an effective non-pharmacological nursing intervention to help reduce perineal pain and improve the comfort of postpartum mothers with episiotomies during the care period.

At the research location at PT. Ansaf Inti Resource, there are several mining stages such as exploration. In the exploration itself, drilling and logging activities are carried out. However, if not careful in calculating coal resource estimates, there can be potential discrepancies between the estimated coal resources based on the results of drilling data identification and well logging data with the actual results. Exploration activities are activities that are often carried out by companies to determine reserves in an area. Without carrying out these activities, companies will have difficulty estimating the profits to be obtained. To obtain the data needed to carry out exploration activities such as calculating the quality and quantity of coal, it is necessary to carry out drilling such as the full coring method and also carry out logging activities to complete the data and also as comparative data from core drilling. Coal Resources are part of a coal deposit in the form of a certain quantity and have reasonable prospects that allow for economic consideration. Coal resources are divided according to the level of geological confidence into inferred, indicated, and measured categories. Therefore, in this study, the author will calculate coal resources from exploration data collection such as coring data, cutting data, and well logging data as well as coal quality data and process it in Minescape 5.7 software so that it can obtain an estimate of coal resources for each seam at the research location.

Gorontalo Province has abundant freshwater resources, yet lacks integrated and sustainable aquaculture facilities. This article presents the conceptual design of a Freshwater Fish Aquaculture Center in Gorontalo Province as a response to this condition, applying Ecological Architecture as the primary design approach. The designed area accommodates various activities including freshwater fish cultivation, education, tourism, as well as research and development of fisheries technology. The method used is a qualitative descriptive approach through literature studies, field observations, interviews, and precedent studies. The design results show that the area can be divided into four main zones: the aquaculture zone, education zone, tourism zone, and supporting zone. The ecological approach is realized through the use of natural lighting and ventilation, environmentally friendly materials, an integrated water management system, and the maximization of green open spaces. This design is expected to increase fisheries productivity while promoting community empowerment through educational activities and environmentally sustainable tourism.

This study aims to analyze the role of the Regional Disaster Management Agency (BPBD) of East Flores Regency in managing the eruption disaster of Mount Lewotobi Laki-Laki during the pre-disaster, emergency response, and post-disaster phases. The study employed a descriptive qualitative method involving 18 informants from BPBD and affected communities in Wulanggitang and Ile Bura Sub-districts. Data were collected through observation, interviews, and documentation. The findings show that during the pre-disaster phase, BPBD implemented preparedness measures through disaster-prone area mapping, the establishment of Disaster Preparedness Teams and Disaster-Resilient Villages, public outreach, and the use of local wisdom. However, outdated contingency plans, limited early warning systems, weak relocation efforts, and low public awareness contributed to panic and casualties during the eruption. In the emergency response phase, BPBD successfully coordinated evacuation efforts, established emergency posts, and distributed logistics effectively. Nevertheless, displaced communities experienced discomfort due to prolonged emergency conditions and limited fulfillment of basic needs in temporary shelters. In the post-disaster phase, BPBD conducted rehabilitation and reconstruction through transportation recovery, trauma healing programs, and permanent housing development based on the Rehabilitation and Reconstruction Plan (R3P). However, limited funding and delays in reconstruction processes remained major challenges. Therefore, improving coordination, institutional capacity, disaster communication, and community participation is essential for effective disaster management.

The development of digital technology has encouraged the transformation of the financial sector through the emergence of Sharia financial technology (fintech) as a financial service based on Islamic principles that emphasize justice, transparency, and public benefit (maslahah). The presence of various Sharia fintech products such as Sharia peer-to-peer (P2P) lending, Sharia crowdfunding, Sharia E-wallets, and digital ZISWAF (zakat, infaq, alms, and waqf) services is considered capable of increasing financial inclusion in Indonesia, especially for unbanked communities and MSMEs that have limited access to formal financial services. This study aims to analyze the innovation of Sharia fintech products, their role in increasing financial inclusion, and their conformity with the perspective of Islamic Economic Law. This research uses a qualitative method with a library research approach through collecting data from scientific journals, DSN-MUI fatwas, OJK and Bank Indonesia regulations, as well as various literature related to Sharia fintech published within the last five years. The data analysis technique was carried out descriptively and analytically by examining the concepts, implementation, and regulations of Sharia fintech in Indonesia. The results of the study indicate that Sharia fintech has a strategic role in expanding public access to financial services through the digitalization of financing, payments, and Islamic social fund collection. In addition to increasing Islamic financial inclusion and literacy, Sharia fintech also helps reduce transaction costs, facilitate MSME financing access, and expand the distribution of financial services to remote areas. From a Sharia perspective, the operation of Sharia fintech must continue to adhere to DSN-MUI fatwas and maqashid sharia principles in order to avoid elements of riba, gharar, and maisir and to create justice and public benefit for society. Therefore, Sharia fintech has a great opportunity to support the development of an inclusive and sustainable Islamic digital economy in Indonesia, although strengthening regulations, Sharia supervision, public education, and product innovation based on community needs are still required.

Although Indonesia has integrated SDG 6 goals into national development planning, access to safe drinking water and sanitation remains a challenge in rural areas, particularly due to suboptimal policy implementation at the local level. The PAMSIMAS program is a government policy designed to improve access to clean water and sanitation services thru a community empowerment approach. This research aims to analyze the implementation of the PAMSIMAS program policy in supporting the achievement of SDG 6 in Mentaras Village, Dukun District, Gresik Regency. The research approach is descriptive qualitative with data collection thru observation, interviews, and documentation. The analysis was conducted using George C. Edwards III's policy implementation model, which includes communication, resources, executor disposition, and bureaucratic structure. The research results show that the program implementation has achieved significant progress, marked by an increase in the number of households accessing clean water, affordable service costs, and community-based management thru BP-SPAMS and BUMDes that reflect the principle of accountability. However, the implementation of the program still faces challenges such as limited service coverage, an imbalance in the facilitator-to-beneficiary ratio, and coordination obstacles among implementing stakeholders. Therefore, strengthening the dimensions of communication, resources, and institutional coordination is necessary to enhance the effectiveness of program implementation and support the achievement of SDG 6 targets by 2030.

This study aims to understand the role of E-Commerce in building customer loyalty, explain the process of loyalty formation, and assess how customers perceive service quality in relation to loyalty, using the GoFood service in Jombang as a case study. The rapid growth of online food delivery services has intensified competition, making customer loyalty a critical factor for sustainability. Employing a qualitative case study approach, data were collected through in-depth interviews with 30 GoFood customers and several drivers in the Jombang area. The findings reveal that E-Commerce platforms significantly enhance loyalty through user-friendly application interfaces, supporting features (such as live tracking, history, and digital payments), and beneficial promotions. The loyalty formation process occurs gradually through consistent positive experiences, moving from customer satisfaction to trust, and ultimately to habitual use. Crucially, the quality of driver services—including politeness, effective communication, punctuality, and order accuracy—emerged as a key determinant of customer comfort and repeat orders. This study implies that for E-Commerce platforms to maintain a competitive edge, strategies must integrate digital convenience with consistently reliable human interactions. The research contributes empirical insights from a semi-urban Indonesian context, highlighting that customer loyalty is not merely transactional but is built on a combination of technological ease, economic value, and positive interpersonal service experiences.

PT. X is a textile company that produces greige fabric. One of the crucial stages in the greige fabric production process is inspection. Currently, the facility layout of the inspection area at PT X is still suboptimal. This results in longer fabric movement distances and increased time, leading to delivery delays and higher material handling costs. This study aims to design an optimal facility layout in the inspection area using the Activity Relationship Chart (ARC) method and to determine the distances, times, and costs for the proposed layout. In the initial production layout, the fabric movement distance reached 26,130 meters in one working day, and the fabric movement time was 936 minutes. Furthermore, the initial production layout generated a relatively high OMH of Rp 13,742,980 per month. After designing the facility layout using the Activity Relationship Chart (ARC) and Blockplan methods, the proposed layout was arranged according to the production process sequence, resulting in a smoother material flow. The proposed layout yields 16,830 meters of fabric movement per workday, 660 minutes of required time, and a monthly OMH of Rp 7,945,622, with an efficiency of 39.32%.

This article analyzes the legal status of golf course development, specifically Gunung Geulis Country Club (GGCC) in the Puncak-Bogor Area within Indonesia's spatial planning policy and Green Open Space (RTH) protection framework, while evaluating its ecological impacts from an environmental justice perspective. Employing a normative juridical method with statutory, conceptual, and case-based approaches, this research identifies two core issues. First, golf course development occupies a legal grey area: it is recognized as private RTH under Article 29(2) of Law No. 26 of 2007 on Spatial Planning, yet substantively fails to fulfill the ecological functions mandated by law due to its exclusivity and inaccessibility to the public. Second, from an environmental justice perspective, GGCC's development generates layered distributive, procedural, and corrective injustices: surrounding communities bear the burden of groundwater contamination, reduced spring discharge, increased surface runoff, and flood risk, while economic and recreational benefits are concentrated among a small number of high-fee members. Weak AMDAL instruments, minimal public participation, and inconsistent spatial monitoring in the Puncak-Bogor protected area exacerbate these conditions. This article recommends policy reforms including stricter private RTH definitions, strengthened participatory AMDAL processes, and consistent application of the polluter-pays principle.

This study analyzes the urgency of strengthening citizen lawsuit mechanisms in response to spatial planning failures from an environmental law perspective, using the 2025 floods in Bali as a case study. The study is motivated by the increasing frequency and intensity of floods, which can no longer be understood as merely natural phenomena, but rather as the result of structural failures in spatial planning management and weak government accountability. Normatively, spatial planning is regulated under Undang Undang Nomor 26 Tahun 2007 dan Undang Undang Nomor 32 Tahun 2009 however, its implementation reveals a gap between legal norms and actual practice. The methodology employed is a normative legal approach, involving an analysis of legislation, legal doctrine, and judicial practices related to citizen lawsuits. The study's findings show that land-use conversion and development in water catchment areas, which go against the precautionary principle, the polluter pays principle, and sustainable development, are examples of spatial planning violations that cause flooding in Bali. In this situation, citizen lawsuits increase public access to justice while acting as a legal tool to hold the state responsible for its carelessness. However, this mechanism's effectiveness is still limited by the absence of a clear legal foundation, the difficulty of the burden of proof, and the public's limited access to the litigation process. Therefore, in order for citizen lawsuits to serve as effective tools for environmental protection and accountability, it is imperative that clear regulations be established, procedures be streamlined, and public access and ability information be improved.

Dengue Hemorrhagic Fever (DHF) remains a major public health problem in Indonesia, particularly in densely populated areas. Control efforts require accurate data and spatial analysis to understand disease distribution patterns. Geographic Information System (GIS) is an effective tool for visualizing case distribution and supporting surveillance and planning of control programs at the primary healthcare level. This study aims to describe the spatial distribution of Dengue cases based on medical record data and produce a geographic distribution map to support Dengue control efforts at the Puskesmas level. This study used a quantitative descriptive design with secondary data from medical records at Karangsari Health Center. The sample consisted of 255 DHF patients in 2025, selected using a total sampling technique. Data were processed through editing, geocoding patient addresses, and spatial analysis using QGIS software.The results showed 255 Dengue  cases in 2025 with fluctuating monthly trends, peaking in April and lowest in December. Case distribution was uneven and tended to cluster. High-risk areas accounted for 15.7%–21.2%, moderate-risk areas 9.8%–15.7%, and low-risk areas 7.1%–9.8%. Megu Cilik Village had the highest proportion of cases, while other villages were categorized as moderate and low risk. This pattern indicates that Dengue incidence is influenced by environmental conditions, vector density, host factors, rainfall, and Aedes aegypti presence. GIS provides clearer spatial visualization, helping identify high-risk areas and supporting targeted public health interventions.

The search and booking of boarding houses (kost) remain a significant challenge for newcomers in campus areas, particularly in Kelurahan Samata, home to UIN Alauddin Makassar, which admits approximately 15,000 new students annually. Many of these students come from outside the region and require temporary accommodation near the campus. This issue is primarily caused by limited access to information and the lack of an optimal system to support the search and booking process. Therefore, it is necessary to evaluate the level of user acceptance of the developed system. This study aims to analyze user acceptance of a boarding house search and booking information system in the case of Kelurahan Samata using the User Acceptance Testing (UAT) method. UAT is a testing approach used to determine whether a system meets user requirements, is accepted according to expected standards, and to identify the need for further improvements to ensure its feasibility for use. The UAT was conducted by end users, namely boarding house seekers and property owners/managers, by responding to 10 evaluation indicators: (1) ease of search, (2) time efficiency, (3) booking process, (4) geospatial search features, (5) completeness of information, (6) availability of suitable boarding houses, (7) accuracy of information, (8) ease of payment process, (9) check-in scheduling, and (10) navigation features for directions. The results of the User Acceptance Testing (UAT) indicate that the system achieved an average score of 87.77, suggesting that the system is highly acceptable and significantly facilitates users. These findings demonstrate that the system is well received by users, confirming that it functions effectively and is capable of accommodating all required functionalities.

Public facilities play an important role in supporting community activities, especially in sports and social interaction. However, inadequate maintenance can reduce their functionality and user comfort. This study aims to improve the function of public facilities through the revitalization of a badminton court area at the Technical Implementation Unit for Road and Bridge Management in Surabaya, making it more feasible, safe, and comfortable for use. The study employs a quantitative descriptive approach combined with Participatory Action Research (PAR), with data collected through direct observation of facility conditions before and after revitalization. The results show a significant improvement in the quality of infrastructure, both in physical condition and environmental comfort. The revitalized court supports better sports activities and increases user participation. These findings indicate that revitalization not only enhances facility quality but also promotes greater utilization, improved social interaction, and a more productive environment, demonstrating its effectiveness in optimizing public facility functions.
