Member of Badan Kejuruan Elektro - Persatuan Insinyur Indonesia
Due to global demands for environmentally friendly and sustainable energy sources, renewable energy (RE) is increasingly utilized across different sectors, including commercial infrastructure. Therefore, many researchers and professionals actively study and implement RE solutions in this sector. This paper aims to review the role and contribution of integrated renewable energy (IRE) for advancing sustainable commercial infrastructure sector. This study method has five steps: search for related papers using keywords on Google Scholar, review all 276 papers and establishment 15 energy sources, map and represent data using tables and charts, analyze and discuss based on tables and charts, and make a conclusion including emerging and future research direction. The study results show IRE originating from solar PV (26%) and wind energy (18%), as well as non-RE i.e., batteries (13%) and on-grid connections (12%), play the most dominant role. Furthermore, the three categories that utilize the most IRE are charging and refueling stations (23%), settlement (19%), and industrial (11%). Solar PV and wind energy remain prominent contributors to sustainable clean energy due to their abundant availability, mature technology, and the ability to address intermittency through battery integration and on-grid connections. Additionally, they are cost-effective and require less land than other renewable energy sources (RES) such as hydro, marine, geothermal, solar thermal, and bioenergy. Each of these sources has its own challenges and cost factors to consider. This review facilitates IRE tracking across commercial infrastructure sector with various categories and sub-categories. Future research increasingly prioritizes green hydrogen fuel cells (8%) for efficient applications.

Arizal Rachmat Zulkiefli, S.Farm
Jakarta Global University
Fingerroot (Boesenbergia rotunda) contains lipophilic constituents with anti-inflammatory potential, but poor aqueous dispersion may limit oral delivery. This study formulated n-hexane rhizome extract into a self-nanoemulsifying drug delivery system (SNEDDS) and evaluated its physicochemical characteristics and in vivo activity. Three virgin coconut oil/Tween 80/polyethylene glycol 400 compositions were screened. Twenty-five male Wistar rats were randomized into negative control, blank SNEDDS, unformulated extract, extract-loaded F1, or diclofenac groups (n = 5/group). Extract and diclofenac doses were 10 mg/kg. Carrageenan-induced paw edema was monitored for 5 h; serial changes and area under the curve (AUC) were analyzed using mixed ANOVA and one-way ANOVA with Tukey HSD, respectively. Selected F1 (10:80:10% w/w) exhibited 98.218 ± 0.067% transmittance, a Z-average diameter of 16.66 ± 0.23 nm, polydispersity index of 0.409 ± 0.012, and zeta potential of -10.98 ± 1.14 mV. No visible separation occurred during stress testing. F1 produced a 12.6% lower AUC than unformulated extract (p = 0.0055), with cumulative inhibition of 39.6% versus 30.8%; diclofenac remained more effective. Blank SNEDDS did not differ significantly from negative control. Consistent with another herbal SNEDDS study (Latifani et al., 2024), F1 enhanced antiedematous activity. Pharmacokinetic and quantitative post-stress studies are needed to establish absorption effects and physicochemical stability.

Snakehead fish (Channa striata) extract contains proteins, albumin, amino acids, and fatty acids that may support its application as a topical moisturizing ingredient. This study aimed to formulate C. striata extract into a topical moisturizing cream and evaluate its physical characteristics, stability, safety, sensory acceptability, and effectiveness in reducing transepidermal water loss (TEWL). A laboratory experimental study was conducted using four oil-in-water cream formulations containing 0%, 3%, 4%, and 5% C. striata extract (F0âF3). The formulations were evaluated for organoleptic properties, homogeneity, pH, viscosity, spreadability, emulsion type, physical stability, primary irritation, and hedonic acceptance. TEWL was measured before and after 14 days of use of the extract-free formulation (F0) and the selected formulation (F3) in 20 panelists. All formulations were homogeneous and remained physically stable after three cycling-test cycles, with a primary irritation index of 0.00. F3 demonstrated the highest sensory acceptance. TEWL decreased from 13.24 ± 0.31 to 10.76 ± 0.41 in F3, corresponding to a reduction of 2.48 ± 0.31, compared with 0.52 ± 0.30 for F0. The difference in TEWL reduction was significant (Z = â3.931, p < 0.001). The 5% C. striata extract cream demonstrated favorable physical characteristics, stability, safety, acceptability, and a greater reduction in TEWL than the extract-free formulation.

Oxidative stress contributes to hair and scalp damage, highlighting the need for antioxidant-based hair-care formulations. This study aimed to formulate a hair essence containing snakehead fish (Channa striata) and black seed (Nigella sativa) extracts and evaluate its physicochemical properties, stability, preliminary irritation potential, acceptability, and antioxidant activity. Four formulations were prepared: F0 (base without extracts), F1 (2% Channa striata and 2% Nigella sativa), F2 (3% and 4%), and F3 (4% and 6%). Physical quality was assessed through organoleptic, homogeneity, pH, viscosity, and cycling stability tests, alongside irritation and hedonic evaluations. Antioxidant activity was measured using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay at 517 nm. All formulations were homogeneous and free of sediment, with pH values of 4.84â6.27 and viscosities of 370.1â1,044.7 cP, and remained stable following cycling tests. No irritation was observed under the study conditions (primary irritation index = 0.00), and hedonic ratings did not differ significantly among formulations (p > 0.05). The half-maximal inhibitory concentrations (ICâ â) of F0, F1, F2, and F3 were 198.844, 46.485, 31.834, and 24.591 ”g/mL, respectively. The individual Channa striata and Nigella sativa extracts yielded ICâ â values of 24.126 and 15.005 ”g/mL, respectively. F3 demonstrated the strongest antioxidant activity among the formulations. These findings support further development of the combined-extract hair essence as a potential antioxidant-based hair-care product.

Design and Implementation of a Web-Based Decision Support System for Vulnerability Assessment and Penetration Testing
Zulfadli
Universitas Bung Hatta
Cybersecurity threats targeting public service web applications continue to escalate, as evidenced by over 609 million cyberattack incidents recorded in Indonesia in 2024. Most public web portals lack structured security evaluation mechanisms, leaving them exposed to potential exploitation. To address this issue, this study designs and implements a web-based decision support system using Vulnerability Assessment and Penetration Testing (VAPT) integrated with the Weighted Sum Model (WSM). The proposed framework combines three security utilitiesâNmap, Nikto, and OWASP ZAPâunder a black box testing methodology. Raw scan logs are parsed and evaluated across three risk dimensions: Severity Level, Exploitability, and Service Impact. These variables are weighted using WSM to generate a unified DSS Security Score, classify vulnerabilities into risk categories (Low, Medium, and High Risk), and provide actionable mitigation guidelines. The engine was deployed as an automated web application built with Python. Comparative evaluations between manual assessments and the automated DSS VAPT platform demonstrated strong alignment across core metrics, including server identification, HTTPS configuration, and missing security headers. The system successfully automated log aggregation, multi-tool data fusion, and risk ranking. The proposed platform offers a structured, data-driven decision-making tool for public web service administrators to prioritize security remediations systematically.

Ir. Mohammad Farhan, S.T., M.T.
Universitas Pancasila
The pre application characteristics of nanofluid formulations are important because differences in base fluid composition and dispersed material can modify thermal and chemical behavior before the fluid is introduced into a thermal system. This study comparatively evaluates four representative formulations based on distilled water, glycerol, palm oil mill effluent (POME) waste biochar, and titanium dioxide (TiOâ). The formulations were distilled water 75% + glycerol 25% : distilled water 74.9% + glycerol 25% + POME biochar 0.1% produced at 600â : distilled water 99.9% + POME biochar 0.1% produced at 600â : and distilled water 74% + glycerol 25% + TiOâ 1%. POME derived material was thermally processed at 600â for 2 h. Particle containing formulations were homogenized by magnetic stirring at 1000 rpm and 60â for 60 min, followed by ultrasonication at 60â for 90 min. Characterization comprised measured pH and calculated mixture density, particle volume fraction, and thermal conductivity using the Maxwell based relation adopted in the validated dataset. The water rich POME biochar formulation produced the highest thermal conductivity value (0.61446 W/m·K) and pH (10.2), while the TiOâ formulation produced the highest calculated density (1.066 g/ml) and particle volume fraction (0.002519). The results show that base fluid composition and dispersed material affect thermal, chemical, and calculated mixture characteristics differently.

Pharmacological Evaluation of Ethanol Extract of Red Roselle (Hibiscus sabdariffa L.) Flowers: Antihypertensive and Anti-Inflammatory in Rat Models
Dr. apt. Nurmeilis, M.Si
UIN Syarif Hidayatullah Jakarta
Hibiscus sabdariffa L. (red roselle) is a medicinal plant known for its potential antihypertensive and anti-inflammatory properties. This study aimed to evaluate both activities of ethanol extract of red roselle flowers in experimental rat models. Antihypertensive activity was assessed in SpragueâDawley rats with hypertension induced by sodium chloride (NaCl) and prednisone, while anti-inflammatory activity was evaluated using a carrageenan-induced paw edema model. For each experiment, animals were divided into five groups, including a negative control, a positive control, and three extract-treated groups. Extract doses were 25, 50, and 100 mg/kgBW for the antihypertensive study and 150, 300, and 600 mg/kgBW for the anti-inflammatory study. Hypertension was induced for 14 days, followed by six days of treatment. Blood pressure and heart rate were measured using a CODAÂź system, while paw volume was assessed using a digital plethysmometer. The extract significantly reduced systolic blood pressure, diastolic blood pressure, and heart rate compared with the negative control (p < 0.05). At dose 100 mg/kgBW, reductions of 15.59%, 26.19%, and 27.14% were observed, respectively. The extract also significantly inhibited carrageenan-induced paw edema at all tested doses (p †0.05), with the highest inhibition of 87.5% at 600 mg/kg BW. The effects of the 300 and 600 mg/kgBW doses were not significantly different from those of the positive control at the respective observation time points (p > 0.05). These findings demonstrate the antihypertensive and anti-inflammatory potential of red roselle flower extract, with activity varying according to dose range and therapeutic endpoint.

Arief Budi Winarno, S.Tr.T., M.Tr.T.
Jakarta Global University
Soft soil conditions in Gedebage, Bandung, pose significant challenges for road construction due to their low bearing capacity and high settlement rates. This study investigates the feasibility of stabilizing soft Gedebage soil using Bledug Kuwu mud and phosphoric acid. Laboratory tests were conducted to evaluate the California Bearing Ratio (CBR) values of untreated soil compared to soil treated with varying proportions of Bledug Kuwu mud and phosphoric acid. The results indicate that soil stabilization effectively reduces plasticity and enhances density, resulting in improved CBR values under both unsoaked and soaked conditions. The maximum reduction in Plasticity Index (PI), up to 54.35%, was observed with the highest content of Bledug Kuwu mud. Compaction tests revealed adjustments in optimal moisture content and maximum dry density with increasing proportions of stabilization materials. Specifically, the optimal moisture content decreased from 36.5% to 33.71%, while the maximum dry density increased from 1.186 g/cmÂł to 1.251 g/cmÂł with the highest stabilization material content. The CBR tests showed significant enhancements after stabilization, particularly under soaked conditions, suggesting substantial improvements in soil strength suitable for road subgrade applications in similar soft soil environments. This research contributes valuable insights into sustainable infrastructure development practices in Indonesia, highlighting the potential of locally sourced materials like Bledug Kuwu mud and phosphoric acid as effective and environmentally friendly soil stabilization agents.

Structural Performance Enhancement of Reinforced Concrete Slabs Using Fiber Reinforced Polymer (FRP) Under Telecom Tower Overloading
Susanti ST., MT.
Jakarta Global University
Many existing reinforced concrete buildings face severe overloading when their functions change unexpectedly. A prime example is a three-story commercial ruko in Indonesia, where a telecommunication base transceiver station (BTS) tower was installed on the rooftop post-construction. This study was conducted to evaluate the structural risks of this setup and design a proper retrofitting solution. First, field investigations using non-destructive testing (NDT)â specifically rebound hammer, ultrasonic pulse velocity (UPV), and rebar scanningâwere carried out to find the actual structural properties. The tests verified an existing concrete compressive strength of 30.057 MPa. Using these real-world parameters, a 3D structural model was built in ETABS. The simulation incorporated the actual dimensions of the frame: 270x300 mm columns, 200x500 mm beams, and a 100 mm thick rooftop slab. The numerical results showed that the 100 mm slab could not support the heavy concentrated load from the tower base, creating dangerous deficiencies in both flexure and shear. Traditional steel jacketing was rejected because it would add too much dead weight to the lower structure. Instead, an alternative retrofitting design using Carbon Fiber Reinforced Polymer (CFRP) sheets was proposed and analyzed. Calculations showed that bonding a single layer of FRS CS N300 CFRP sheets directly to the critical areas effectively restored the structural capacity. The final demand-to-capacity moment ratio from 1.669 dropped to a safe 0.84, fully satisfying the safety criteria of SNI 1726:2019. Ultimately, this case study proves that FRP wraps offer a fast, lightweight, and non-corrosive solution for strengthening overloaded urban infrastructure.

Sustaining QRIS Usage among Indonesian Micro-Entrepreneurs: The Mediating Role of Continuance Intention
Dr. Dyah Cahyasari, S.E., M.M.
Jakarta Global University
Digital transformation in the financial sector has introduced various non-cash payment instruments, including QRIS (Quick Response Code Indonesian Standard), the national QR code payment standard developed by Bank Indonesia. However, QRIS adoption among micro, small, and medium-sized enterprises (MSMEs) remains suboptimal, highlighting the need for a deeper understanding of the factors influencing its usage behavior. This study examines the effects of social influence, financial habits, and digital financial literacy on QRIS usage behavior through intention to continue using. A quantitative approach was employed, involving micro-entrepreneurs in Java and Sumatra, Indonesia. The research model integrates Behavioral Finance as the grand theory, Financial Literacy Theory as the middle-range theory, and UTAUT2 as the applied theory. The PLS-SEM results indicate that social influence, financial habits, and intention to continue using have positive and significant direct effects on QRIS usage behavior. In contrast, digital financial literacy does not exhibit a significant positive direct effect on usage behavior. Social influence, financial habits, and digital financial literacy have positive and significant effects on intention to continue using. Furthermore, intention to continue using significantly mediates the effects of social influence, financial habits, and digital financial literacy on QRIS usage behavior, with positive indirect effects. These findings suggest that the three factors can strengthen QRIS usage behavior by fostering entrepreneursâ intention to continue using this payment method.

Dwi Rachmawati S.S.T., M.Mgt.
Jakarta Global University
Purpose: Micro, small, and medium enterprises (MSMEs) in the food sector face supply chain and digital capability constraints, yet little is known about how data capability translates into better supply chain management. This study examines the effect of Data Analytics Capability (DAC) on Supply Chain Management (SCM) among food MSMEs in West Java, and tests whether Digital Transformation (TD) mediates this relationship. Design/methodology/approach: A quantitative, cross-sectional survey was administered to 400 respondents from food-sector MSMEs (restaurants, eateries, catering, and mobile food businesses) in West Java. The sample size was determined with the Lemeshow formula at a 5% margin of error (n = 384, rounded up to 400), and respondents were selected through multistage cluster random sampling. The questionnaire contained 26 indicators (DAC: 11, TD: 3, SCM: 12) on a five-point Likert scale. Data were analyzed with PLS-SEM using SmartPLS 4.1, and significance was tested through bootstrapping. Findings: The measurement model met the criteria for convergent validity, discriminant validity, and reliability. DAC had a positive and significant effect on TD (ÎČ = 0.424, p < 0.001), and TD had a positive and significant effect on SCM (ÎČ = 0.339, p < 0.001). The indirect effect of DAC on SCM through TD was also significant (ÎČ = 0.144, p < 0.001), alongside a significant direct effect (ÎČ = 0.364, p < 0.001), indicating complementary partial mediation. TD accounted for 28.4% of the total effect. The model explained 18.0% of the variance in TD and 35.2% in SCM.
