Career selection is an important process for students at Darussalam Gontor University (UNIDA) because it influences their academic development and future employment. However, many UNIDA students experience difficulties in determining suitable careers due to a lack of understanding of their psychological characteristics. This study aims to build a Decision Support System (DSS) for career recommendations for UNIDA students based on psychological test results using the Simple Additive Weighting (SAW) method. The psychological data used are non-clinical test results collected through a structured questionnaire from six respondents and converted into numerical scores. The research stages include determining criteria and weights, compiling a decision matrix, normalization process, calculating preference values, and ranking career alternatives using SAW. The career alternatives used consist of academics, corporate professionals, entrepreneurs, managers, and social/public services. The results show that the managerial career alternative obtained the highest preference value of 0.861, followed by entrepreneurs at 0.824, corporate professionals at 0.778, social/public services at 0.737, and academics at 0.703. These findings demonstrate that the SAW method is capable of providing objective and systematic career recommendations based on the psychological profiles of UNIDA students. This research is expected to assist UNIDA students and academics in making more informed career decisions tailored to individual characteristics

This research is an evaluative study of the old urban area of Kesawan in Medan City, which has been part of the city’s revitalization efforts initiated by the Medan City Government. Kesawan possesses strong historical and colonial architectural character but has undergone functional and visual degradation due to uncontrolled modern urban development. One of the key issues identified is the presence of inactive urban spaces, disconnected from the public realm and lacking social meaning—phenomena recognized in urban theory as lost space. This concept serves as the foundation for evaluating the effectiveness of the revitalization program implemented since 2021. The study employs a qualitative approach using a single-case study method, focusing on Kesawan as a complex urban space. Data were collected through field observations, in-depth interviews with five categories of informants (building owners, visitors, security personnel, street vendors, and architects), and visual documentation. The analysis adopts the theoretical framework of Finding Lost Space by Roger Trancik (1986), which comprises three main approaches: Figure-Ground Theory, Linkage Theory, and Place Theory. These were further elaborated into six evaluative indicators: connectivity, continuity and circulation, enclosure, accessibility, visual orientation, and the meaning and perception of space by the public. The findings indicate that revitalization has brought significant visual improvements and physical enhancements, particularly along the main corridor of Jalan Ahmad Yani I–VII. However, many secondary streets and non-priority areas still exhibit characteristics of lost space, such as disconnected pedestrian paths, underutilized voids, weak spatial integration, and limited social engagement. These conditions suggest that the revitalization outcomes remain uneven and predominantly cosmetic in certain areas. The study recommends integrating spatial and social approaches in future urban revitalization policies to ensure that public space functions can be restored holistically, sustainably, and contextually in line with local identity.

Violence against children and women at home and in the workplace is a serious social problem, but there has been little response from society and law enforcement. The National Child Protection Commission (KPAI, 2018) received complaints related to cases of physical violence and victimization of children as much as 72%, followed by psychological violence at 9%, economic violence or bullying/intimidation at 4%, and sexual violence at 2%. The National Children's Commission also reported that the majority of perpetrators of violence against children were parents, 44% of whom were biological mothers, 22% mothers and stepfathers, 18% biological fathers, and 8% caregivers. The aim of this activity is to increase respondents' knowledge regarding the impact of violence on mothers and children. Socialization methods in the form of lectures and questions and answers are used in this activity. It was found that respondents were very enthusiastic about listening to the material presented by the presenters. The conclusion from this activity is that violence against mothers and children must be opposed to prevent the impact that will occur on children.

This research aims to design an Islamic Boarding School (Ponpes) with a sustainable architecture approach that is able to answer environmental, social, and economic challenges holistically.

One of the negative impacts of the mining process is acid mine drainage which is formed from the oxidation of minerals containing iron sulfur, such as pyrite (FeS2) and pyrothite (FeS) by oxidizers such as water and oxygen. To handle or control acid mine drainage, one way is to use activated carbon or often referred to as activated charcoal, which is a type of carbon that has a very large surface area. Charcoal is a porous solid that contains 85% to 95% carbon, produced from materials containing carbon by heating at high temperatures without oxygen (pyrolysis). Activated carbon made from palm shells is an adsorbent that can be used to treat coal mine acid water, so that the water meets standards for flowing into the environment. This study used concentration variants of 4 grams, 6 grams, 8 grams and contact times of 30 minutes, 60 minutes and 150 minutes. The results of this study show that the concentration of palm oil shell activated carbon adsorbent influences the reduction of iron (Fe) and manganese (Mn) metal levels as well as the pH conditions in acid mine drainage water. The higher the concentration and the longer the contact time, the more heavy metals are adsorbed, the contact time is the highest. The optimal concentration in this study was 150 minutes and the optimal concentration was 8 grams with physical activation.

This study aims to examine the effect of varying the length of oil palm empty fruit bunch (EFB) fibers on the mechanical properties and macrostructure of Palmfiber Reinforced Concrete (PRC) as an alternative to Glassfiber Reinforced Concrete (GRC). EFB fibers were selected due to their abundance, eco-friendliness, and potential to enhance the mechanical properties of lightweight concrete. The methods employed include flexural testing and macrostructural observation using five fiber length variations (3 cm, 4 cm, 5 cm, 6 cm, and 7 cm). The results show that a fiber length of 5 cm produced the highest flexural stress of 11.78 kg/cm², while a length of 4 cm yielded the highest modulus of elasticity at 162.2 kg/cm². Macrostructural observations revealed good bonding between fibers and matrix in most specimens, although performance differences were observed due to fiber distribution and manual compaction processes. In conclusion, fiber length affects the mechanical performance of PRC, yet production process optimization is necessary to achieve more consistent results.

Particularly in tropical nations like Indonesia and Malaysia, oil palm plantations have grown to be a significant economic sector worldwide. Although these plantations offer substantial economic advantages, there are a number of environmental effects associated with their growth that must be taken into account. The ecological effects of oil palm plantations, such as deforestation, biodiversity loss, greenhouse gas emissions, and air and land pollution, are covered in this article. It also covers mitigation techniques, such the use of sustainable farming methods, ecosystem poisoning, and ecosystem restoration, to strike a balance between financial gains and environmental extinction. Without compromising its financial gains, the palm oil sector may grow in a more ecologically responsible way with the correct strategy.

This research aims to design an Aircraft Jacking control system for the Boeing 737-800 to automatically balance the aircraft's inclination using an MPU6050 sensor and servo actuators. The system can detect pitch and roll angles with an accuracy of ±0.5° and an average response time of 150 ms. Based on tests using five datasets, the balancing time ranges from 400 to 600 ms, depending on the initial imbalance. In Dataset 5, with a pitch of 3.5° and a roll of -2.3°, the system required 600 ms to achieve balance, demonstrating its ability to handle critical conditions. The servo actuators successfully adjusted the jacking height within a range of 2 cm with a precision of ±0.02 cm, while the OLED-based monitoring system allowed operators to observe the inclination angles in real-time. Furthermore, ESP-NOW-based communication achieved a data transmission success rate of 98%, supporting efficient centralized control. This research demonstrates the system's effectiveness in balancing the aircraft quickly and accurately, providing a foundation for further development under extreme conditions and energy efficiency improvements.

In carrying out structured maintenance, a method is needed to increase the durability of an aircraft component, one of the methods used is the reliability method. The reliability of aircraft components is very necessary to ensure that each aircraft component is serviceable and runs according to its function in the aircraft system, so to increase the reliability of an aircraft component, the reliability method is very important to do. This study aims to determine the critical life time limit of the asset or system or equipment function and identify the failure mode that occurs in the Gas Turbine Engine component of the Boeing 737-500 aircraft because if this engine fails, it can result in flight delays and if not handled immediately can cause the aircraft to experience Aircraft on Ground (AOG) conditions, because it has the potential to disrupt airworthiness and threaten safety. This study uses exploratory research which aims to simplify problems to make them easier to solve. This study uses the Pareto diagram method to determine the highest type of failure in components, then analyzes it using the failure mode effect analysis (FMEA) method. Based on FMECA and FTA analysis, there are 3 failure modes, the failure modes include mechanical system (Bleed Valve), pneumatic system (Butterfly Shaft), electrical system (actuator). The failure was due to the occurrence of the top event part consumable, namely the bleed valve part with an RPN value of 192, followed by the butterfly shaft part with an RPN value of 75 and the Actuator part with an RPN value of 72. The pneumatic system and electrical system categories are prioritized to carry out preventive maintenance, which means it is a solution from industry players in an effort to maximize maintenance of the turbofan engine system accompanied by technical or economic analysis to ensure a system in extending the service life of parts in the aircraft system.
