This research aims to design a Solar Power System (PLTS) for households that can meet an energy demand of 4.5 kWh per day. The system design takes into account the efficiency of solar panels and the average solar radiation potential in Semarang, which is around 5 hours per day. The method used in this research involves calculating the required solar panel capacity based on the daily energy needs of the household, panel efficiency, and solar radiation hours. The calculation results show that the required PLTS capacity is 1125 Wp, which is then designed using 4 solar panels with a capacity of 300 Wp each. This system is expected to allow households to meet their energy needs independently and sustainably. The implication of this research is to provide an alternative solution for households in reducing their dependence on conventional energy sources, while contributing to the effort to reduce greenhouse gas emissions.

Drainage is an infrastructure system designed to channel water from one place to another. This study is based on Article 2 of the Regulation of the Minister of Public Works of the Republic of Indonesia No. 12 of 2014 concerning the Implementation of Urban Drainage Systems. This research aims to analyze the drainage maintenance carried out by the Public Works and Housing Office (PUPR) of Pekanbaru City using Dhillon B.S’s asset maintenance theory, which consists of two main indicators: preventive maintenance and corrective maintenance. This study employs a qualitative approach with data collection methods including in-depth interviews and field observations. The results indicate that drainage maintenance in Pekanbaru City faces several challenges, such as budget constraints, low public awareness, a shortage of skilled labor, outdated infrastructure conditions, and the impact of extreme weather conditions. The findings suggest that the drainage maintenance efforts by the PUPR Office of Pekanbaru City still encounter numerous challenges, particularly in technical aspects and community participation. Therefore, it is necessary to increase the budget and develop more competent human resources in the field of drainage maintenance. Additionally, more intensive public awareness campaigns on the importance of maintaining drainage cleanliness and the enforcement of penalties for violators should be strengthened. The utilization of modern technology, such as sensors and drone-based monitoring systems, can also serve as a solution to enhance the effectiveness of drainage maintenance. With these measures, it is expected that the drainage system in Pekanbaru City can function more optimally and sustainably.

The East Java Provincial Government established the East Java Super Corridor (EJSC) in five regions, including Bojonegoro Regency, to provide coworking spaces for the public. EJSC Bakorwil Bojonegoro is the only coworking space in the area, making it essential to offer high-quality services. This study aims to describe the service quality of the coworking space at EJSC Bakorwil Bojonegoro using a descriptive qualitative method. This research focuses on the five service quality indicators proposed by Kotler and Keller (2016): reliability, responsiveness, assurance, empathy, and tangibles. Data were collected through interviews, observations, documentation, and literature studies, with data analysis involving collection, reduction, presentation, and conclusion drawing. The findings indicate that the service quality of the coworking space at EJSC Bakorwil Bojonegoro is generally satisfactory. Reliability is reflected in the provision of free facilities that support user productivity. However, responsiveness still faces challenges in terms of timely responses to complaints and the flexibility of operating hours. Assurance has been established through effective communication, although staff professionalism needs improvement. Empathy is demonstrated through warm and responsive interactions between management and users. Tangibles indicate that the available facilities are adequate, but some shortcomings remain, such as limited parking space and suboptimal workspace arrangement.

Flight delays represent a significant challenge in the aviation industry, affecting passenger satisfaction and trust in airlines. Minister of Transportation Regulation No. 89 of 2015 mandates airlines to provide compensation to passengers experiencing flight delays. Lion Air, as one of the largest airline networks in Indonesia, is expected to effectively implement this policy, particularly at Weda Bay Nickel Airport. This study employs a qualitative approach to gain an in-depth understanding of how Lion Air fulfills its responsibility in compensating passengers. Data were collected through interviews with Lion Air personnel, including check-in staff, technicians, and flight attendants, as well as direct field observations. The research was conducted over a specific period to ensure the collected data is relevant and accurately reflects on-ground conditions. The analysis results indicate that Lion Air has implemented compensation policies in accordance with PM 89 of 2015, providing compensation in the form of beverages, snacks, full meals, and cash payments of up to IDR 300,000, depending on the delay duration. Although the policy has been executed, several key challenges remain, including limited communication with passengers and suboptimal internal division coordination. Passengers often feel inadequately informed during delays, reducing their satisfaction levels. Furthermore, operational constraints such as spare part delays and weather factors also pose challenges in minimizing delay durations.

The immaturity of the gastrointestinal tract of preterm infants can increase the prevalence of feeding intolerance that must be addressed by nurses. Massage is considered effective and is often used in neonatal intensive care. This study aims to identify the effectiveness of complementary therapy in the form of abdominal massage as a nursing implementation strategy for premature infants with feeding intolerance in the NICU. The study method refers to the PRISMA 2020 checklist with the following keywords: "Feeding Intolerance" AND "Newborn" OR "Premature" AND "Abdominal massage" AND "Neonatal Intensive Care Unit" AND "Nursing". Article searches were conducted on Google Scholar, Springer Link, Scopus, and PubMed databases by applying several criteria including full-text articles relevant to the study objectives, written in Indonesian or English, published in the last 3 years, and using experimental study designs, then continued critical appraisal using the Joanna Briggs Institute (JBI) instrument. Based on the search results, 74 articles were found and after screening only 5 articles were used. The results of the study showed that abdominal massage was considered to have a positive impact on reducing the residual volume of the stomach, vomiting behavior, and abdominal distension. Based on this, it is recommended that abdominal massage can be performed at least twice per day to control feeding intolerance in preterm infants in the neonatal intensive care unit.

The consumer goods industry, including the tobacco sector, plays a critical role in Indonesia's economy. Despite facing intense competition and regulatory challenges, this sector contributes significantly to national revenue through taxes and duties. Indonesia, with one of the highest smoking rates globally, saw substantial revenue from Tobacco Excise Duties (CHT), amounting to IDR 198.02 trillion in 2022. The COVID-19 pandemic exacerbated challenges by causing significant tax hikes, leading to reduced purchasing power and increased demand for illegal cigarettes. This study focuses on PT HM Sampoerna Tbk, a major player in the Indonesian tobacco industry, evaluating its financial performance using the Du Pont System for the years 2020-2022. The analysis reveals fluctuating Return On Equity (ROE), a declining Net Profit Margin (NPM), and Return On Assets (ROA), despite stable Total Assets Turnover (TATO) and Equity Multiplier (EM). The findings highlight the impact of external economic pressures and regulatory changes on the company's profitability and operational efficiency. This study provides insights into how financial performance metrics reflect the broader economic context and the effectiveness of management strategies.
