This study aims to analyze the price elasticity of demand and supply of local lemon oranges in Indonesia, a key horticultural commodity. The data used are historical records of prices and demand in Sleman Regency (2003–2006), as well as consumption and supply in Medan City (2010–2011). The research adopts a quantitative approach using price elasticity analysis with the midpoint formula. The results show that demand is inelastic (Ed < 1), meaning that price changes do not significantly affect lemon demand. On the other hand, supply is elastic (Es > 1), indicating a strong producer response to price changes. These findings are essential for price-setting strategies, production increase planning, and managerial decision-making in maintaining the stability of local lemon supply and prices in the domestic market.

At preschool age, the development of kinesthetic intelligence is strongly influenced by stimulation provided through varied physical activities and games. One approach that can be used by teachers is through games, especially obstacle games or handicap games. These games are designed to provide structured physical challenges, so that children are encouraged to develop gross motor skills, balance, agility, and overall body coordination. This study aims to determine the improvement of grossmotor skills through simple obstacle games. This research is a Classroom Action Research (PTK). The subjects in this study were children in the age range of 5-6 Years at ABA Bustanul 10 Medan Kindergarten ,namely 10 people .Datacollection was done by observation and non-test. This observation is used to determine the ability ofstudents in gross motor skills, the data is analyzed by the percentage formula. The result soft here searc hobtain edwere BB 30%, MB 40%,BSH 20%,BSB 10%.IncycleI and in cycle II BB 0%, MB 20%, BSH 20%, BSB 60%. Gross motor skills in developing kinesthetic intelligence of children aged 5-6 years through simple obstacle games in cycle I only reached completeness with a value of 10% (Less), and in cycle II it increased classically with a value of 60% (Very good). Thus the improvement of gross motor skills of children aged 5-6 years through simple obstacle games can improve gross motor skills in developing kinesthetic intelligence of children aged 5-6 years.

The demand for goats for religious rituals such as aqiqah and qurban during Eid al-Adha has shown a significant upward trend each year, in line with the growing awareness among Muslims to observe religious practices in accordance with Islamic law. This study aims to explore the strategies employed and the challenges faced by traditional goat farmers in responding to this evolving demand. A descriptive qualitative approach was used, with data collected through in-depth interviews, field observations, and documentation. The subject of this study was Mr. Anto, an experienced goat farmer and trader who manages the “Adinda Aqiqah” business in Medan City. The findings reveal that Mr. Anto’s main strategies include stock management through the raising of hundreds of goats of various breeds (Kacang, Etawa, and sheep), the selection of high-productivity superior breeds, and the setting of competitive selling prices for both qurban and aqiqah needs. On the other hand, the primary challenges encountered include limited infrastructure, particularly at sales locations, animal health risks due to adverse weather conditions, and the lack of effectiveness in using social media as a marketing tool to reach a wider consumer base. These findings offer a clear picture of how traditional livestock practices adapt to market demands, while also highlighting the need for improvements in technology, marketing, and policy support to enhance competitiveness in this dynamic, seasonal market.

These results highlight the importance of adaptive coping training and psychological support to promote healthier stress management among students.

Thus, this study concludes that understanding demand patterns and price adaptability are the main key factors in maintaining the business continuity of traders in the traditional market of MMTC Medan.

This study aims to examine the potential and challenges of utilizing Solar Power Plants (PLTS) in Medan City, which is geographically located near the equator and receives high exposure to sunlight throughout the year. The method used is a literature review with a narrative review approach that analyzes secondary data from various journals and relevant scientific articles. The results of the study show that Medan City has an average annual horizontal global solar radiation intensity of 463.61 W/m², with the potential for electrical power that can be generated from rooftop solar panels reaching 748.57 MW (monocrystalline), 598.85 MW (polycrystalline), and 299.43 MW (thin film). This potential is comparable to the capacity of large-scale power plants. The use of PLTS contributes to reducing carbon emissions, increasing energy security, creating jobs, and developing the local economy. However, challenges such as high installation costs, limited suitability of roof structures, and low public awareness are still major obstacles in the implementation of this technology. Therefore, synergy is needed between government policies, public education, and technological innovation to optimize the use of solar energy in urban areas such as Medan.

This study aims to examine the ethical and moral considerations of judges in imposing verdicts against perpetrators of the crime of child intercourse, as reflected in Decision Number 147/Pid.Sus/2023/PN Kpg. This case is complex because the perpetrator and the victim are both still classified as minors and sexual relations occurred on the basis of consensual, but are still qualified as criminal acts based on positive Indonesian law. The main focus of this study is how judges balance protection for victims with justice for perpetrators who are also still in their childhood, as well as the extent to which the principle of restorative justice is applied in the verdict. This study uses an empirical juridical method with a qualitative approach, which relies on document studies, interviews, and analysis of court decisions. The theories used in the analysis are the theories of restorative justice, substantive justice, and child protection in the criminal justice system. The results of the study showed that the judge imposed criminal punishment on the perpetrator even though there were elements of agreement and the status of the perpetrator who was still a child. The judge's main consideration is the legal protection of children as absolute victims. However, judges do not optimally consider the approach to coaching and restorative justice as regulated in the juvenile justice system. The victim's family's refusal to mediate was also a factor that strengthened the criminal verdict. On the other hand, there is an inequality in the application of the principle of fairness, because the perpetrator is not fully positioned as a child who also needs protection and coaching.

The type of research is normative legal research. The research data collection technique uses literature studies. The data will then be analyzed using qualitative analysis. The results of the study show that based on the theory of criminal responsibility, a person with a mental disorder cannot be punished because he is considered not to have the awareness and ability to be responsible or his actions, but there is a submission in the case of periodic mental disorders experienced by the defendant in the sentence, the legal status of the perpetrator does not immediately get a full element of forgiveness, in the audit the judge considered it worthy of being held criminally responsible because his actions had fulfilled the elements of criminal responsibility. The judge's decision ignored the conditions of the conversation with a history of periodic mental disorders showing weaknesses in aspects, legal certainty, benefits and protection of human rights, in contrast to the principles of legalization and violation of national law and imprisoning people who have a history or even are mentally ill does not provide benefits to the person himself.
