This study aims to explore how interpersonal communication plays a role in the process of constructing self-identity within the “Jemuah Keos” community in Surabaya. This community functions as an alternative social space inhabited by individuals with diverse creative backgrounds, such as musicians, motorcycle builders, visual artists, and subculture enthusiasts. The formation of identity in this community is not solely driven by individual expression but also shaped through social interactions that are reflective and rich in meaningful symbols. The study uses a qualitative approach with a descriptive case study method. Data were collected through participatory observation, semi-structured interviews with nine informants, and documentation of various visual artifacts representing the community’s activities. The data analysis process follows the interactive model by Miles and Huberman, which consists of three main stages: data reduction, data presentation, and drawing conclusions. The theoretical framework used in this study refers to Joseph A. DeVito's concept of interpersonal communication, which includes self-disclosure, empathy, emotional support, symbolic exchange, social values, as well as reflective interaction and role negotiation in social relationships. The findings indicate that interpersonal communication is a key element in shaping and negotiating personal identity. Cultural symbols such as clothing style, vehicle modifications, visual language, and daily interaction patterns become primary means of identity expression. The "Jemuah Keos" community demonstrates openness, equality, and a critical stance against the dominance of mainstream culture. Interpersonal communication within this community also plays a role in building collective solidarity and voicing critical views on existing cultural standards. The identity formed is not only personal but also part of a larger community identity.

This study investigates the influence of financial literacy and lifestyle on financial management among gym members at USB Fitness. Financial literacy refers to the ability to understand and apply financial concepts, while lifestyle encompasses spending patterns, consumption preferences, and daily habits. Low financial literacy combined with a high-consumption lifestyle can negatively impact personal financial management, potentially leading to poor budgeting, excessive debt, and limited savings.The research adopts a quantitative approach using a survey method, with data collected through structured questionnaires distributed via Google Forms. The population comprises 60 registered gym members, from which a sample of 52 respondents was determined using the Slovin formula with a margin of error of 5%. Data analysis techniques involve both partial (t-test) and simultaneous (F-test) hypothesis testing to assess the effects of the independent variables—financial literacy and lifestyle—on the dependent variable, financial management.The t-test results indicate that financial literacy has a positive and significant effect on financial management (t-count = 6.384 > t-table = 2.00958; p-value = 0.000 < 0.05), suggesting that higher financial literacy levels contribute to more effective personal financial practices. Conversely, lifestyle shows no significant effect on financial management (t-count = -0.013; p-value = 0.990 > 0.05), indicating that lifestyle variations among respondents do not directly determine their financial management capabilities.Simultaneous testing through the F-test reveals that financial literacy and lifestyle together have a significant influence on financial management (F-count = 21.333 > F-table = 3.191; p-value = 0.000 < 0.05). This suggests that while lifestyle alone may not significantly impact financial management, its interaction with financial literacy can influence financial outcomes.The study concludes that improving financial literacy among gym members is essential for enhancing financial management skills, while lifestyle modifications may only be impactful when supported by strong financial knowledge.

Camshaft lift is an important parameter that determines the height of the valve lift, calculated from the valve position when it is completely closed to the fully open position. This component plays a crucial role in regulating the flow of the air and fuel mixture into the combustion chamber. This study aims to improve the performance of a 200cc 4-stroke motorcycle engine through camshaft lift modification, which is expected to affect the characteristics of engine torque and power. Modifications were carried out by designing two types of modified camshafts, namely series A and series B, as a comparison to the standard camshaft. The research method used is experimental testing using a dynamometer to measure engine torque and power at various speeds, ranging from 4,000 to 10,000 RPM. The data obtained were analyzed to determine the effect of each type of camshaft on engine performance. The test results show that the B series camshaft provides the most significant performance improvement compared to the standard and A series camshafts. At 7,500 RPM, the standard camshaft produces an average torque of 19.2 Nm, the A series camshaft 19.6 Nm, while the B series camshaft reaches 21.2 Nm. Meanwhile, at 10,000 RPM, the average power of the standard camshaft is recorded at 22.2 HP, the A series camshaft 24.1 HP, and the B series camshaft reaches 26.3 HP. This increase indicates that the camshaft lift modification is able to optimize the duration and height of the valve opening, so that the supply of the fuel and air mixture to the combustion chamber becomes more efficient. Thus, camshaft modification, especially the B series, is an effective and applicable solution in increasing the performance output of a 200cc motorcycle engine without having to make major changes to the overall engine structure.

Air circulation and natural lighting are among the key aspects influencing the comfort of room usage, particularly in dormitory buildings inhabited by university students. This study aims to explore thermal comfort more deeply, focusing on air circulation and natural lighting within student dormitory rooms in the Riau Islands. A qualitative method was employed, collecting up-to-date data on the selected building. Building simulations using Computational Fluid Dynamics (CFD) and DIALux were conducted to analyze the speed of air circulation and the quality of natural lighting within the rooms. The results reveal that prior to evaluation, the dormitory rooms faced thermal issues related to poor air circulation and insufficient natural lighting. Wind speed was recorded at less than 2 m/s, and the incoming and outgoing airflow collided due to the presence of only one ventilation access. The evaluation using cross-ventilation through room openings showed a positive impact on indoor air circulation, increasing wind speeds to 2–4 m/s. The cross-ventilation concept also enhanced the discharge and exchange of indoor air, preventing air stagnation. In terms of natural lighting, the simulation showed that lighting intensity in several rooms was below the minimum standard of 250 lux, particularly in areas far from the window openings. After modifications to the window layout and the addition of secondary light-transmitting elements, the lighting level significantly improved to meet the recommended standard. These findings highlight the importance of incorporating both passive ventilation and natural lighting strategies in student dormitory designs. Improving these environmental aspects not only enhances thermal comfort but also supports the health, productivity, and well-being of the residents. This study contributes to the growing body of research on sustainable dormitory design and can be used as a reference for future architectural planning and policy improvements.

This study explores the ethical perspectives of genetic editing from two distinct frameworks: Islamic bioethics and global medical ethics. Both ethical systems emphasize the protection of human dignity and the prevention of harm, aligning with the broader goal of promoting health. However, significant differences emerge when addressing the issue of genetic editing, particularly in relation to human procreation. While global bioethics focuses on universal human rights, Islamic bioethics introduces religious principles rooted in Sharia law, such as Maqasid al-Sharia (objectives of Sharia) and Maslahah (public interest), to guide the ethical evaluation of genetic technologies. The findings reveal that while both frameworks agree on the importance of medical necessity, the treatment-enhancement distinction plays a critical role in Islamic perspectives, leading to more cautious stances on genetic modifications aimed at enhancing non-medical traits. The study also underscores the cultural and regional variations in Islamic bioethics, reflecting how different Islamic schools of thought impact fatwa decisions on genetic editing. In comparison, global bioethics aims to establish universal principles, often focusing on human rights, equality, and equity. The paper concludes by recommending more inclusive discussions between Islamic scholars and global bioethicists to bridge the gap between religious ethics and global standards. This would help ensure that genetic technologies are applied ethically, respecting both cultural values and universal human rights, and addressing the challenges posed by emerging genetic technologies.

The education system in Indonesia comprises a series of interconnected components and educational activities aimed at achieving national education goals. With the growing demands for educational reform, policies related to education have undergone several modifications. Every individual in the country has the right and obligation to attain a decent life; however, in reality, many are still unable to experience genuine well-being. This situation arises because the government and leaders tend to prioritize rights over fulfilling their responsibilities. The methodology employed is qualitative, The research findings indicate that the education policies implemented have not yet fully reached all segments of society, particularly vulnerable groups, despite the presence of public participation in forums such as Musrenbang. Moreover, the success of implementation largely depends on effective coordination between central and regional governments, as well as adequate socio-political support.

The utilization of clam shells as adsorbents has attracted considerable attention due to their ability to adsorb contaminants such as heavy metals, hazardous substances, and oil. Clam shells, which are composed mainly of calcium carbonate (CaCO₃), possess a porous structure that favors adsorption. Calcium carbonate imparts alkaline properties that neutralize acidic effluents and promote the formation of precipitates. Physical and chemical modifications can enhance the surface area and porosity of the shell, thereby enlarging the active sites for contaminant sorption. Clam shells heavy metals such as Pb, Cd, Hg, organic substances and can be used for oil spill remediation due to their hydrophobic and oleophilic properties. The calcination process converts the shells into a material that contaminants such as TSS, COD, and BOD. This utilization not only mitigates pollution but also creates opportunities for adsorbent products with economic value, especially in coastal areas where shell waste is abundant. However, this application must take into account ecological and health impacts, as overharvesting and non-environmentally friendly processing can damage the ecosystem. A sustainable approach with environmentally friendly regulations and technologies is essential to maximize the benefits of clam shells as adsorbents.  

One of the key processes in the production of APAR cylinders is the welding of cylindrical plates, which is carried out using a Longitudinal Welding Cylinder machine and the CO₂ welding method. However, in practice, operators face several challenges, mainly due to the number of process steps that do not significantly contribute to the quantity or quality of the output, resulting in reduced productivity. This study aims to improve the productivity of the welding process through a series of improvements. The methods used include data analysis and root cause identification through the Overall Equipment Effectiveness (OEE) approach and Lean Six Sigma using the DMAIC stages (Define, Measure, Analyze, Improve, Control). Based on the Define stage, the initial OEE value was 67.49%, which is still far below the world-class standard of 85%. In the Measure stage, Pareto analysis revealed that the largest downtime (2,097 minutes or 40%) was caused by cycle time issues. Further analysis showed that activities such as material setup, additional plate placement, and additional plate cutting (totaling 85 seconds) could still be optimized. During the Improve stage, modifications were made, such as eliminating the additional plate cutting process and adding a stopper to ensure accurate welding alignment. These improvements successfully reduced the cycle time from 180 seconds to 120 seconds, thereby decreasing downtime and increasing the OEE value to 76.12%.
