Abstract

This study investigates the combination of Fly Ash (FA), Bottom Ash (BA), and Soil (S) as a potential bottom liner in landfills. It is expected to cover the need for sustainable environmental technology, maintain structural strength, and prevent heavy metal pollution in rapidly urbanizing areas, while considering problems related to urban waste management. Aim: Evaluate FABA-Soil mixture as an alternative bottom liner material in landfill by assessing geotechnical performance and Cadmium (Cd) adsorption capacity. Methodology and results: The research explores two issues: mechanical stability (specific gravity, void ratio, compaction, and permeability) and mitigating Cadmium contamination from landfill leachate. Four mixture compositions (FBS1-FBS4), 15%, 30%, 50%, and 65% FABA content, were tested. Laboratory tests are conducted, including compaction, permeability, and adsorption continuous column tests. The results showed that intermediate FABA content (FBS2 and FBS3) may have stronger mechanical stability compared to others. For permeability, all values exceeded the regulatory standard. In the case of adsorption capacity, all compositions effectively removed Cd from the leachate. Conclusion, significance, and the impact study: Results on void ratio (e) and maximum dry density (MDD) suggested that a suitable mixture design may enhance long-term mechanical performance under a normal urban landfill loading situation. The FABA-soil mixture shows promise as an alternative landfill liner in moderate proportions and demonstrates excellent adsorption of heavy metals. All the attributes support general objectives of sustainable urban development and circular resource management, align with sustainable cities and communities, and responsible consumption and production.

Abstract

Waste level monitoring is still often done manually, making it inefficient in preventing accumulation. Ultrasonic sensors are widely used because they are practical and affordable, but their accuracy is often affected by environmental and hardware conditions. This study aims to compare the Kalman Filter and Exponential Moving Average methods to improve the accuracy of ultrasonic sensor readings in an automated waste monitoring system. The type of research used is an experiment with a microcontroller-based system that is tested on various waste height variations. The Kalman Filter combines previous estimates with new data, while the Exponential Moving Average gives more weight to the most recent value. The performance of both methods is assessed based on measurement consistency and error rate.The data was then analyzed quantitatively using Root Mean Square Error (RMSE).The results show that the Kalman Filter produces lower errors and more stable data compared to the Exponential Moving Average or raw data. In conclusion, the Kalman Filter is more effective in improving the reliability and accuracy of the automated waste monitoring system. The implications of this research suggest that selecting the right sensor type can significantly improve system performance in detecting waste capacity in real time.

Abstract

Divorce is widely viewed as a means of resolving marital conflict; however, it has the potential to negatively affect adolescents. For adolescents, parental divorce is one of the most stressful life events, often associated with long-term emotional and behavioral problems. As a result of their parents' divorce, adolescents feel depressed and struggle to cope with lifes challenges into adulthood. Forgiveness is proven to mitigate the negative impact of parental divorce, enabling adolescents to adapt and bounce back and preparing them to face future challenges both physically and psychologically. This research aims to determine the relationship between forgiveness and resilience in 104 adolescent survivors of parental divorce in Aceh, using quota sampling and participated in completing the Brief Resilience Scale (BRS) and Transgression-Related Interpersonal Motivations (TRIM-18). The data analysis shows a significance value (p) =0.001 and a correlation coefficient (r) = -0.631, indicates significant positive correlation between forgiveness and resilience. This implies that the higher the level of forgiveness, the higher the level of resilience, and conversely, the lower the level of forgiveness, the lower the level of resilience. This research found that these adolescent have high levels of both forgiveness and resilience.Perceraian umumnya dianggap sebagai resolusi konflik interpersonal dalam pernikahan, tetapi fenomena ini dapat berdampak negatif bagi remaja. Bagi remaja, perceraian orang tua adalah salah satu peristiwa kehidupan yang berpotensi menimbulkan stres dikaitkan dengan masalah emosional dan masalah perilaku jangka panjang. Akibat dari perceraian orang tua, remaja merasa tertekan dan kesulitan menghadapi tantangan hidup hingga dewasa. Resiliensi dan pemaafan terbukti dapat mengurangi dampak negatif yang ditimbulkan dari perceraian orang tua sehingga remaja mampu beradaptasi dan bangkit kembali dan remaja siap secara fisik dan psikologis untuk menghadapi tantangan di masa depan. Penelitian ini bertujuan untuk mengetahui hubungan pemaafan dengan resiliensi pada 104 remaja penyintas perceraian orang tua di Aceh yang dipilih menggunakan teknik quota sampling dan berpartisipasi dalam pengisian instrumen Brief Resilience Scale (BRS) dan Transgression-Related Interpersonal Motivations (TRIM-18). Analisis data menunjukkan nilai signifikansi (p) =0.001 dan nilai koefisien korelasi (r) = -0.631, artinya terdapat hubungan positif signifikan antara pemaafan dengan resiliensi. Penelitian ini menemukan bahwa semakin tinggi pemaafan maka semakin tinggi resiliensi, begitu juga sebaliknya semakin rendah pemaafan maka semakin rendah resiliensi. Penelitian ini menemukan bahwa remaja penyintas perceraian orang tua memiliki pemaafan yang tinggi serta resiliensi yang tinggi.

Abstract

Research on dispositional forgiveness has primarily concentrated on the intraindividual level. The aim of this study is to analyze dispositional forgiveness using ecological systems theory, with a systematic review and thematic analysis technique. A literature search was performed from 2018 to 2025 in a range of electronic databases: Scopus, PubMed, Google Scholar, and Science Direct. Of 26,550 results from the searches, 15 articles fulfilled the inclusion criteria and were chosen for analysis. Thematic analysis indicates that dispositional forgiveness research is primarily undertaken within the microsystem, including personality, well-being, resilience, self-efficacy, emotional intelligence, self-acceptance, attachment and anxiety. Studies on macrosystem dimensions, involving cultural and historical variables that determine individual forgiveness, are limited. Researchers can use the findings of this study as a reference to perform exploratory research on cultural values and historical circumstances that influence forgiveness attributes. Empirical research is also needed, particularly on children. Keywords: dispositional forgiveness; ecological systems theory; microsystem; systematic review

Abstract

Pneumonia is an acute respiratory infection and a leading cause of child mortality worldwide, with exposure to cigarette smoke identified as one of its risk factors. This study aims to determine the relationship between exposure to cigarette smoke and the incidence of pneumonia in children aged 1–4 years at RSUD dr. La Palaloi Maros. A descriptive analytic design with a cross-sectional approach was used, involving 55 children diagnosed with pneumonia based on medical record data and selected through total sampling. The results showed that most pneumonia cases occurred in children aged 1–2 years (62.5%) and were more common in boys (65.0%). Among the 40 children diagnosed with pneumonia, 35 (63.61%) were exposed to cigarette smoke. Statistical analysis using the Chi-Square test indicated a significant association between exposure to cigarette smoke and the incidence of pneumonia (p = 0.000). This study concludes that cigarette smoke exposure is significantly associated with pneumonia in children aged 1–4 years. It is therefore recommended that parents create a healthier home environment by avoiding smoking indoors as a preventive measure.

Abstract

Transportation problems experienced by UD. Raja Wangi in distributing Maha Dewa fragrant incense. UD. Raja Wangi incurs high transportation costs due to irregular direct distribution patterns and has not paid attention to the route to be passed. One way to solve the problem is to use transportation methods to get the optimal distribution route so that the transportation costs incurred are minimal. This study aims to solve transportation problems using the Bilqis Chastine Erma (BCE) method and the Sumathi Sathiya method with the Stepping Stone method to obtain the optimal solution. The Bilqis Chastine Erma (BCE) and the Sumathi Sathiya methods are indirect methods of solving transportation problems by obtaining an initial solution. After obtaining the initial solution, the Stepping Stone method is used to obtain the optimal solution. The results showed that the optimal solution using the Stepping Stone method based on the initial solution of the Bilqis Chastine Erma (BCE) method obtained a total transportation cost of Rp42,937.00 while the optimal solution using the Stepping Stone method based on the initial solution of the Sumathi Sathiya method obtained a total transportation cost of Rp38,727.00. In addition, the Sumathi Sathiya method gets a difference in total transportation costs of Rp11,790.00 or 23% of the total transportation costs incurred by the UD. Raja Wangi. Therefore, the Sumathi Sathiya method is the best solution for minimizing transportation costs.

Abstract

Konflik antara hukum dan nilai-nilai etika yang terjadi terkadang dianggap hanyalah masalah pribadi individu, terutama jika konflik tersebut bersinggungan dengan nilai-nilai etika yang dianut individu tersebut dan standar kode etik tidak menjelaskan dengan baik keadaan tersebut. Pada saat konflik tersebut muncul, individu harus terlibat dalam proses pengambilan keputusan yang etis (ethical decision making) untuk mengevaluasi alternatif dari pemecahan masalah yang mungkin dipilih dan menentukan pilihan yang terbaik. Penelitian ini bertujuan untuk mengetahui bagaimana dinamika pengambilan keputusan etis pada Oditur di Pengadilan Militer Banda Aceh. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Prosedur pengambilan responden menggunakan teknik purposive sampling dengan jumlah responden dua orang. Data penelitian dikumpulkan melalui wawancara dan observasi. Hasil penelitian menunjukkan bahwa pengambilan keputusan yang dilakukan oleh kedua responden dalam mengambil keputusan untuk menuntut lamanya hukuman yang akan diberikan kepada terdakwa telah melalui enam langkah-langkah yang sama yaitu mengidentifikasi masalah, mempertimbangkan makna dari keadaan dan peraturan, mengindentifikasi dan menggunakan sumber-sumber etika dan hukum, mempertimbangkan keyakinan dan nilai-nilai pribadi, mengembangkan solusi yang dapat menyelesaikan masalah dan menetapkan serta memilih waktu bertindak. Penelitian ini juga menemukan adanya dilema dan konflik batin didalam pengambilan keputusan serta faktor emosi dan asal suku yang sama memengaruhi pengambilan dalam menuntut.Conflict between the law and ethical values that occur is sometimes considered just a personal problem of individuals, especially if the conflict intersects with the ethical values embraced by the individual and ethical standards did not explain well the situation. When conflict arises, the individual must engage in an ethical decision making process to evaluate alternatives of solving problems that may have and determine the best option. This study aims to determine the dynamics of decision-making at the Military Court Prosecutor in Banda Aceh. This study used a qualitative method with case study approach. Making procedures of respondents using purposive sampling with the number of two respondents. Data were collected through interviews and observations. The results showed that the decision made by the two respondents in the decision to prosecute the length of the punishment that will be given to the accused have been through the same six steps that identify the problem, consider the significance of the context and setting, identify and use ethical and legal resources, consider personal beliefs and values, develop possible solutions to the problem, choose and implement a course of action and assess the outcome. The study also found their dilemmas and inner conflicts in decision-making as well as emotional factors and the same ethnic origin in a decision affecting prosecution
