Abstract

Palm Oil Mill Effluent (POME) is abundantly available in the palm oil industry and has significant potential for generating renewable energy, specifically biogas, through the biogasification process. This study investigates the relationship between the reduction of Chemical Oxygen Demand (COD) values and pH changes in POME during the biogas production process. The study employs a Completely Randomized Design (CRD) with a single factor and four levels. Data were analyzed over five observation periods spanning 24 days. The results show a significant decrease in COD concentration from 96,300 mg/L on day 0 to 22,720 mg/L on day 24. This reduction is attributed to microbial activity, with Effective Microorganisms (EM4) being used in this research. Additionally, an inverse relationship between pH and COD was observed, where an increase in pH correlated with a decrease in COD. Biogas production also increased over time, with the cumulative biogas volume reaching 5.2 liters on day 24. The study concludes that more alkaline environmental conditions support the activity of microorganisms responsible for COD reduction and higher biogas production. Recommendations for future research include adding parameters such as temperature and Volatile Fatty Acids (VFA), and further investigation into more effective and efficient microorganism seeding. Thus, this research provides insights into the biogasification process and the development of more efficient and sustainable biogas technology.

Abstract

The Continuous Settling Tank (CST) is a tank at the clarification station of a palm oil mill used for the sedimentation process of oil, water, and sludge. The optimal performance of the CST is evaluated based on the overflow produced, considering the quality of water content and the level of oil impurities according to standards. Controlling the percentage of impurities in the oil requires an optimal thickness level during collection. The thickness of the fluid layer in the CST tank can be measured using a bamboo stick. However, the bamboo used to measure the fluid thickness is inaccurate because the bamboo inserted into the CST tank, with the expectation that sludge will adhere to it, is often cleaned by the oil layer, and the bamboo has to be inserted repeatedly, making it inefficient. Therefore, it is necessary to create a device to measure oil thickness based on Archimedes' principle, using a float. The objective of this research is to create a measuring device to control the quality of crude oil in the Continuous Settling Tank based on the oil thickness. The design of this research uses two methods: descriptive and experimental. The research results show that after the implementation of the measuring device as a thickness indicator, oil quality control in the CST becomes efficient. With an oil thickness of 50 cm, the average quality of crude oil is observed to be the best, with a water content of 0.45% and an impurity level of 0.49%.

Abstract

This research seeks to see how urban identity influences the culture of the Mandailing ethnic community, especially through marriage customs which have experienced cultural acculturation with other ethnic cultures in the city of Medan. The method used in this research is a descriptive qualitative method with data collection techniques through literature study by examining related sources. The results found several forms of cultural acculturation to customs 1) Mandailing marriage, namely: acculturation to Islamic culture; 2) use of Henna/Mahendi on the bride; 3) Mardandang (Cooking) culture becomes Catering and Rijsttafel. All of these forms of acculturation are a form of group self-defense to maintain their ethnic existence, so they must adapt to the multicultural urban environment.

Abstract

This research was conducted at RA Al-Is Syah Hakim Medan. This type of research is experimental research with a quantitative approach. This research method uses Quasi Experimental Designs with Non Equivalent Control Group Design. The population is 29 children with total sampling technique, so that the entire population is used as a sample. This study aims to determine: (1) linguistic verbal intelligence of children; (2) Linguistic verbal intelligence of children using pop up book media; (3) The significant influence of pop up book media on the linguistic verbal intelligence of children at RA Al-Isyah Hakim Medan. The results of the study show that the use of pop up book media affects the linguistic intelligence of children aged 5-6 years. This is illustrated by the research results which obtained an average pre-test of 26.72 and an average post-test of 52.08. So that the linguistic verbal intelligence of children in the experimental class is better than the control class with an average pre-test of 25 and an average of 44.83 in post-test. Based on the results of the hypothesis testing, tcount > ttable is 3.226> 2.131 with a significant number of α = 0.005 Thus the hypothesis Ho is rejected and Ha is accepted so that it can be stated that there is a significant effect of the use of Pop Up Book Media on Verbal Linguistic Intelligence in Children Aged 5-6 Years at RA Al-Isyah Hakim Medan.

Abstract

Oil losses in crude palm oil (CPO) production significantly impact process efficiency and industrial profitability. This study analyzes the causes and extent of oil losses at various processing stages, including empty fruit bunches, pressed fiber, nuts, and liquid effluent, using Soxhlet extraction with n-hexane solvent. Results indicate that while total oil losses remain within acceptable limits, certain components such as empty fruit bunches and liquid effluent exceed standard thresholds. Key contributing factors include raw material quality (underripe or residual fruit), equipment inefficiencies (such as digester maceration and centrifuge separation), and operational errors. The Soxhlet extraction method proved effective in measuring oil losses due to its ability to separate compounds based on density differences without damaging oil components. This study recommends improvements in sterilization processes, equipment optimization, and enhanced operational monitoring to reduce oil losses. The findings provide valuable insights for the industry to enhance production efficiency and minimize economic losses

Abstract

Penelitian ini bertujuan untuk mengkaji tantangan yang dihadapi guru serta strategi yang diterapkan dalam pengelolaan kelas anak usia dini yang memiliki perbedaan karakteristik dan kemampuan. Studi ini dilakukan di BKB PAUD Al-Muharram dengan pendekatan kualitatif dan desain studi kasus deskriptif. Data dikumpulkan melalui observasi langsung di dalam kelas, wawancara semi-terstruktur dengan guru dan kepala satuan PAUD, serta dokumentasi. Hasil penelitian menunjukkan bahwa keberagaman karakteristik anak, seperti perbedaan kemampuan kognitif, sosial-emosional, serta perilaku, menjadi tantangan utama dalam pengelolaan kelas. Guru menghadapi keterbatasan jumlah tenaga pengajar, kurangnya keterlibatan orang tua, dan kebutuhan untuk mendampingi anak secara individual. Untuk mengatasi tantangan tersebut, guru menerapkan strategi seperti pembelajaran berbasis bermain, pengelompokan berdasarkan kemampuan anak, pendekatan individual, serta memperkuat komunikasi dengan orang tua. Temuan ini menegaskan pentingnya kompetensi guru dalam menciptakan lingkungan belajar yang inklusif, adaptif, dan mendukung perkembangan optimal anak usia dini.
