The Soxhlet extraction method uses repeated heating and solvent circulation to separate substances from mixtures, producing more extract faster than maceration with less solvent. However, this method requires pure solvents and is not suitable for thermolabile compounds as they can be degraded by heat. Soxhlet extraction is more effective for limited quantities of dry and fine herbal materials. This method is widely used to extract phytochemical compounds such as flavonoids, tannins, and curcumin, and has potential in cosmetic raw materials, herbal medicines, and antioxidant products. Although it uses more energy, this technique is efficient and continuous. Modern innovations such as combining it with Ultrasonic Assisted Extraction (UAE) or environmentally friendly microextraction are expected to increase extraction efficiency while reducing the use of organic solvents. Modifications to Soxhlet, including automation and assistive technologies such as high pressure, ultrasound, and microwaves, open up opportunities for commercialization and further research with more optimal results and more practical operations. The modified Soxhlet is considered a “panacea” in extraction due to the significant performance improvements achieved.

The lompong flower is an ornamental plant that requires stable soil moisture conditions and a stable environment so that it can grow optimally.

The results show that the system is able to display moisture data with a good level of accuracy, as well as provide relevant information for users in plant care decision-making. The implementation of this system has proven to be effective in supporting the maintenance of lompong flowers, especially in maintaining soil moisture stability. This research is expected to be a reference for the development of IoT-based ornamental plant monitoring technology, as well as contribute to improving the quality of plant care in a more efficient and measurable manner.

Taxes play a vital role as the primary source of state revenue and a key instrument for financing national development through the State Budget (APBN). This study aims to analyze the determinants of tax compliance among Micro, Small, and Medium Enterprise (MSME) taxpayers in Semarang City, with a particular focus on the effects of tax policy, subjective norms, and financial performance. A quantitative associative approach was employed, using primary data collected through questionnaires distributed to 100 MSME taxpayers selected via purposive sampling. The data was analyzed using the Partial Least Squares (PLS) method with WarpPLS software. The results indicate that tax policy and subjective norms have a positive and significant effect on MSME tax compliance, while financial performance shows no significant effect. The adjusted R² value reveals that the model explains 87.2% of the variance in taxpayer compliance. To enhance MSME tax compliance, the government should simplify tax regulations, strengthen social norms through education and community engagement, and ensure consistent, transparent, and fair implementation of tax policies

This study aims to analyze the influence of work motivation on employee productivity at Kerupuk Uenak Bu Rina, a home-based industry in Boyolali. This research uses a descriptive qualitative approach with data collection techniques through in-depth interviews and direct observation at the business location. The results indicate that work motivation derived from internal factors such as satisfaction with received wages and a familial work environment, as well as external factors in the form of appreciation from the owner, significantly influence employee morale and work output. Employee productivity levels are reflected in the consistency in meeting production targets for two types of crackers and the ability to adapt to demand fluctuations. These findings suggest that improving productivity in micro-enterprises like this one depends not only on technical operational aspects but is also greatly influenced by how work motivation is managed. This research provides practical contributions regarding the importance of paying attention to human resource aspects in managing operational risks and improving the performance of small-scale businesses.

Micro, Small, and Medium-Sized Enterprises (MSMEs) are critical to the Indonesian economy because they provide jobs and boost the local economy. However, MSMEs continue to disregard the Financial Accounting Standards for Micro, Small, and Medium Entities (SAK EMKM). With assistance from the Lampung Provincial Leadership Council (DPP) of the Indonesian Employers Association (APINDO), this study aims to investigate the factors influencing the use of SAK EMKM in MSMEs. SAK EMKM socialization, business size, length of operation, and educational background are among the factors analyzed. Survey-based quantitative approach is used in this study. 107 MSMEs received questionnaires from APINDO DPP Lampung in order to gather primary data. Multiple linear regression analysis, validity tests, reliability tests, and traditional assumption tests were performed on the data using SPSS software. Partial tests (t-tests) and coefficients of determination were used to test hypotheses. The study's findings show that SAK EMKM use in MSMEs supported by APINDO DPP Lampung is influenced by educational background, length of operation, and socialization. Meanwhile, SAK EMKM's use is mostly unaffected by the size of the company. This finding implies that the adoption of SAK EMKM is more influenced by the socialization, business experience, and skill levels of MSME members than by the size of the firm. It is anticipated that this study would help academics and MSME participants use SAK EMKM more effectively in order to achieve sustainable MSME financial management.

Background: Dental caries is a major problem in orodental health, especially in children. The primary cause of caries is the activity of cariogenic microorganisms. Unbalanced remineralization of dental tissue followed by destruction of organic matters may cause cumulative and progressive damage to the tooth structure. Extensive caries lesions that have reached the pulp are an indication for pulp therapy with appropriate crown restoration. Case Report: A 10-year-old boy came with a complaint of a painful cavity in his upper right front tooth. The patient was considered communicative and cooperative. The patient also had a habit of consuming sweets. An intraoral examination revealed extensive caries on the entire surface of 53. A periapical radiograph showed a radiolucent area reaching the pulp cavity on the occlusal surface of 53 with resorption of the apical one-third of the root. Based on the examination results, reversible pulpitis was established as the primary diagnosis. The treatment plan was pulpotomy with a dental crown restoration. Treatment was carried out over four visits. First visit included complete examination, periapical radiography, and pulpotomy. The second visit included core buildup, tooth preparation, and dental impressions. The third visit included try-in and crown insertion, followed by a final follow-up visit. Conclusion: Pulpotomy with dental crown restoration can be an effective clinical approach to restore the function and aesthetics of anterior deciduous teeth, especially in cases that consider aesthetics and cost limitations.

This study aimed to analyse the impact of customer service quality on sales at CV BILCA Digital Printing in Maumere for the 2024-2025 period. Grounded in the SERVQUAL model, this qualitative research posits that the five dimensions–responsiveness, reliability, empathy, assurance, and tangibles–synergistically build customer trust, which in turn drives repeat purchases and word-of-mouth (WOM). The study involved 15 customers selected through purposive sampling. Data were collected via in-depth interviews, participant observation, and internal documentation. Analysis was conducted using the Miles & Huberman model, encompassing data reduction, display, and conclusion drawing. The findings confirm that all five SERVQUAL dimensions collectively cultivate trust, leading to increased repeat purchases and positive WOM. Key results reinforce a “Trust Chain” mechanism: response times of ≤30 minutes and on-time production foster initial trust; personalized interactions strengthen affective bonds; and robust recovery policies reduce perceived risk by exceeding expectations. Notably, no instances of customer churn were observed, as all participants made repeat orders within 24 hours of a positive experience. This study contributes to the services marketing literature by empirically validating trust as a key mediator between service quality dimensions and behavioural outcomes, while also offering a replicable empirical model for Micro, Small, and Medium–sized Enterprises (MSMEs) in the digital printing sector.

Savings and Loan Cooperatives (KSP) play a strategic role as microfinance institutions that promote members' financial welfare through savings and loan services based on trust and togetherness. This study aims to analyze profitability as the basis for financial performance assessment of KSP Credit Union Bahtera Sejahtera Kewapante during the 2023–2025 period. The analysis focuses on three main profitability ratios—Return on Equity (ROE), Profit Margin (PM), and Assets Turnover (AT)—along with interpretation of performance trends, causal factors of fluctuations, and their implications for the cooperative's operational sustainability. The research employs a descriptive quantitative approach with data collection techniques through direct observation, documentation of financial statements for the last three years, and financial ratio analysis. Results indicate a significant decline in profitability performance: ROE decreased from 2.01% (2023) to -0.91% (2024) and slightly improved to -0.25% (2025); Profit Margin fell from 13.81% to -7.75% and -2.24%; while Assets Turnover showed a downward trend from 0.049 times to 0.039 times in 2025. All ratios remain far below ideal standards (ROE ≥10%, PM ≥20%, AT ≥1 time), indicating inefficiency in capital management, insufficient income to cover operational expenses, and low asset productivity. These conditions are caused by declining business income, rising operational costs, and weakening member economic activity. The findings confirm the critical need for optimizing productive loan disbursement, enhancing operational cost efficiency, and increasing active member participation as essential strategies to restore profitability and ensure the long-term sustainability of the cooperative.

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the regional economy, including in Boyolali Regency. However, this contribution has not been fully matched by adequate human resources (HR). The main problem in this study is the still low capacity of MSMEs' human resources, particularly in aspects of managerial skills, digital literacy, and adaptability to changes in the business environment, which impact business performance.

The research method used is a Systematic Literature Review (SLR) with a content analysis approach to relevant scientific literature from the past five years. The research process includes determining inclusion and exclusion criteria, searching for literature sources, thematic coding, and synthesizing research findings. The results show that effective HR development strategies can be grouped into three main aspects: skills training, marketing digitalization, and cross-sector collaboration. These three strategies have been proven to contribute positively to improving MSME competency, operational efficiency, market expansion, and business competitiveness. Thus, human resource development is a key factor in driving sustainable improvement in MSME performance, particularly in facing the challenges of digital transformation and increasingly complex economic competition.

Antibiotics are one of the main pillars in the treatment of bacterial infections and have contributed significantly to increasing human life expectancy. However, long-term use of antibiotics has serious consequences for the balance of the body's microbiome, especially the gut microbiome which plays an important role in maintaining homeostasis through the regulation of the immune system, metabolism, and protection against pathogens. This literature review aims to comprehensively analyze the impact of long-term antibiotic use on the structure, diversity, and function of the human microbiome. The scientific articles reviewed were obtained from PubMed, Scopus, ScienceDirect, and Google Scholar databases, including empirical research, systematic review, and meta-analysis published in the last ten years. The results showed that prolonged exposure to antibiotics consistently decreased microbiota diversity, altered the composition of bacterial communities, and triggered dysbiosis, which is often persistent even when therapy is stopped. Dysbiosis is associated with impaired immune system function, increased systemic inflammation, risk of allergic and metabolic diseases, and potential disorders on the intestinal-brain axis. This impact is more pronounced in vulnerable groups such as neonates and children, especially when exposure occurs during a critical period of development. In conclusion, long-term antibiotic use has broad systemic implications, so a more rational, prudent, and sustainable use strategy is needed to maintain the health of the human microbiome.

Forensic entomology is a branch of forensic science that utilizes insects and other arthropods as biological indicators in death investigations. This discipline plays a crucial role, particularly in cases of advanced decomposition, where conventional forensic methods often face limitations. One of the key contributions of forensic entomology is estimating the post-mortem interval (IPM), or time since death, which can assist investigators in reconstructing the chronology of events. Furthermore, entomological analysis can provide information regarding the location of death, possible movement of the body, and environmental conditions surrounding the crime scene. Common approaches include analyzing insect succession patterns that appear according to the stages of decomposition of the body and determining the age of larvae based on their developmental stage and growth rate. Environmental factors, particularly temperature, humidity, and microhabitat conditions, significantly influence insect development and therefore must be carefully considered in the analysis. This literature review aims to discuss the basic concepts, functions, and role of forensic entomology in law enforcement. Furthermore, this review emphasizes the importance of accurate insect species identification to improve the validity and reliability of the resulting time-of-death estimates.

Community service with the theme of Expired Date (ED) and Beyond Use Date (BUD) aims to improve knowledge and understanding of proper medication storage as an effort to enhance the health of the Gagak Sipat community. Knowledge about medication usage limits and checking product expiration dates educates the public to be more cautious and to avoid health risks that may arise from consuming products that have exceeded their usage period or have expired. The use of medicines beyond their ED and BUD indicates that the drugs may have experienced reduced stability related to storage conditions. Decreased stability of pharmaceutical preparations can affect their physical quality, which in turn impacts the effectiveness and safety of the medication. The educational method used in this program included lectures accompanied by the distribution of leaflets, followed by practical simulations on checking ED and calculating BUD for various dosage forms. The results of this educational activity showed that community members were able to determine the ED and BUD for several pharmaceutical preparations such as tablets, powders, capsules, syrups, eye drops, ear drops, and others. The community in Gagak Sipat village gained an understanding of the risks associated with using medications beyond the BUD, including reduced effectiveness, the risk of microbial contamination, and potentially harmful chemical reactions. It was emphasized that some medications that are expired or used beyond their BUD can pose more serious health risks, especially when used to treat severe diseases.

This study aims to analyze the effect of Tungsten Inert Gas (TIG) welding parameter variations on the mechanical and metallurgical properties of AISI 304 austenitic stainless steel, which is widely used in construction and industrial applications due to its excellent corrosion resistance and joint strength. The research focuses on identifying the optimal welding current to minimize welding defects and enhance joint structural integrity. Welding current was varied at three levels, namely 100 A, 125 A, and 135 A, while other parameters such as welding speed, argon shielding gas flow rate, and electrode type were kept constant. Mechanical properties were evaluated through Micro-Vickers hardness testing conducted in the weld metal, Heat Affected Zone (HAZ), and base metal, as well as tensile testing to determine ultimate tensile strength and elongation. In addition, non-destructive testing using the dye penetrant method was performed to detect surface welding discontinuities. Metallographic analysis was carried out using optical microscopy following an etching process to observe grain morphology, grain size, and the formation of microstructural phases. The results are expected to demonstrate a correlation between increased heat input due to higher welding current and changes in mechanical properties and microstructure, particularly in the HAZ. This study provides practical guidance for determining optimal TIG welding parameters for AISI 304 to achieve high tensile strength, homogeneous hardness distribution, and a stable microstructure resistant to intergranular corrosion.
