Abstract

Kesadaran dalam eksplorasi bahan bakar baru yang dapat diperbaharui telah membawa perkembangan teknologi sampai pada pemanfaatan biomassa. Salah satu biomassa yang memiliki potensi sebagai sumber bahan bakar alternatif adalah blotong hasil limbah pabrik gula. Limbah ini diproduksi dalam jumlah yang sangat banyak dan belum dimanfaatkan secara maksimal. Sebelum digunakan sebagai bahan bakar, blotong perlu diolah menjadi briket (biobriket) agar memiliki kemampuan sebagai bahan bakar rumah tangga dan industri yang lebih baik. Tujuan dari penelitian ini adalah meneliti potensi pembuatan biobriket berbahan baku blotong dinilai dari nilai kalor, waktu nyala, dan waktu pembakaran. Metode yang dilakukan dalam pembuatan biobriket ini dilakukan dengan variasi alur cara kerja pada saat penambahan perekat dan pirolisis, temperatur pirolisis, rasio penambahan perekat, serta waktu pengeringan. Selain itu dilakukan pula variasi tekanan yang dilakukan pada rentang 27,5 kg/cm2 sampai dengan 37,5 kg/cm2 . Kesimpulan yang diperoleh dari penelitian ini adalah metode pembuatan biobriket mempengaruhi waktu nyala, waktu pembakaran, kalor, dan kekuatan mekanis biobriket. Sedangkan tekanan pencetakan hanya mempengaruhi waktu nyala, waktu pembakaran, dan kekuatan mekanis biobriket. Semakin rendah temperatur pirolisis, semakin banyak jumlah arang yang diperoleh, semakin singkat waktu penyalaan dan waktu pembakaran biobriket, dan semakin rendah nilai kalor yang dihasilkan dari pembakaran biobriket. Temperatur pirolisis juga mempengaruhi kuat tekan dari biobriket yang dihasilkan. Semakin banyak tetes tebu yang digunakan, semakin besar kekuatan tekan biobriket (biobriket semakin kompak), waktu nyala akan semakin cepat, waktu pembakaran akan semakin lama. Jenis perekat tetes tebu memiliki nilai kalor yang lebih besar dibandingkan dengan jenis perekat lem kanji. Jenis perekat lem kanji (sampel II) memiliki massa beban maksimum yang lebih besar dibandingkan dengan jenis perekat tetes tebu (sampel I). Kata Kunci : biomassa, biobriket, blotong, pirolisis, tetes tebu

Abstract

This study aims to find out how to implement problem solutions to bullying behavior that tends to occur in Islamic educational institutions. Islamic educational institutions, which in their curriculum are ensured to have a lot of character education content, are considered not optimal in giving strict sanctions to students who are perpetrators of bullying and all other dishonorable acts. This research uses a qualitative descriptive approach. To obtain research data, researchers used open interview techniques with informants. The participants in this study were students from 4 Integrated Islamic Middle Schools in Medan City, totaling 4 students. Data triangulation techniques were also used in this study by checking records from interviews, field notes, surveys and also documentation records from various data obtained. The results of the study show that bullying that occurs in several Integrated Islamic schools does not receive serious attention, teachers and schools often ignore this behavior by not providing consequences or punishments so that bullies feel rewarded or empowered for their actions. The school should not tolerate the slightest bit of disgraceful actions committed by students so that it becomes a deterrent effect for other students and parents are also required to be responsible for providing good ethical education in the family. teachers and schools often ignore this behavior by not giving consequences or punishments so that bullies feel rewarded or empowered for their actions.

Abstract

This study aims to analyze the relationship between workload and work stress in employees of PT. Kemuning Group Medan. The background of the research is based on the phenomenon of increasing demands on company productivity which is often not proportional to the physical and psychological capacity of employees, thus giving rise to symptoms of work stress. The study used a quantitative approach with a correlational method and involved the entire active employee population of 93 people through a total sampling technique. Data was obtained using a four-level Likert scale-based questionnaire that had been tested for validity and reliability, then analyzed by Pearson's Product Moment correlation test through the SPSS program. The results of the descriptive analysis show that the level of workload and work stress of employees is in the high category. Furthermore, the correlation test showed a significant positive relationship with the value of Rxy = 0.809 (p 0.05), where workload contributed 65.4% to work stress. These findings confirm that overload is the dominant factor affecting employee work stress. Practically, the results of the study recommend the need for workload management, stress intervention programs, and social support in the work environment to maintain employee well-being and productivity.

Abstract

The discussion in this empirical study is to find out what variables can influence the achievement of the actual inflation rate variable in Indonesia in the last ten years. The writer considers that achieving the actual inflation rate targeted by a Central Bank is not simply related to supply and demand imbalances for primary goods alone, but more broadly than that related to dynamic micro and macroeconomic conditions. The writer initially suspected that variables such as the inflation target rate, previous inflation rate, loan interest rate, and gross domestic product had a significant influence on fluctuations in the actual inflation rate in Indonesia. After statistical tests were carried out using the secondary data in the form of the rates of the four independent variables and the actual inflation rate in Indonesia as the dependent variable every year for the last ten years it’s found that only the loan interest rate had a significant and positive effect on the actual inflation rate in Indonesia. which means that the higher the loan interest rate will also increase the actual inflation rate. The three other variables tested in this empirical study, namely the inflation target rate, the previous inflation rate, and the gross domestic product rate, did not have a significant effect.

Abstract

High-quality healthcare services are essential to ensure patient satisfaction and sustainable hospital performance. This study aims to analyze patient service quality at the Dental Clinic of Bhayangkara Lemdiklat Police Hospital using the Institute of Medicine (IOM) framework, which includes six dimensions: safety, effectiveness, patient-centeredness, timeliness, efficiency, and equity. A quantitative descriptive design with a survey approach was employed. A total of 94 patients were selected through purposive sampling. Data were collected using a structured questionnaire measuring patients’ expectations and perceived performance. The instrument was tested for validity and reliability, and the data were analyzed using descriptive statistics, paired sample t-tests, regression analysis, and Importance–Performance Analysis (IPA). The results indicate that overall service quality is perceived as good, particularly in effectiveness, safety, and patient-centered care, which obtained the highest mean scores. However, gaps remain in equity, timeliness, and efficiency. Equity showed the lowest mean value and the highest variability, suggesting that patients still perceive unequal treatment and service procedures. Paired sample correlations revealed strong and significant relationships among the IOM dimensions, implying that improvements in one aspect may positively influence others. Regression and ANOVA results indicate that service quality does not significantly differentiate patient types (general and BPJS). The IPA analysis places effectiveness, safety, and patient-centeredness in the “maintain performance” quadrant, while timeliness, efficiency, and equity require strategic improvement. These findings highlight the importance of continuous quality enhancement, particularly in ensuring fair, timely, and efficient dental services
