Abstract

White oyster mushroom (Pleurotus Ostreatus) is a type of wood fungus. The purpose of this study was to determine the growth response of white oyster mushroom (Pleurotus ostreatus) due to the addition of molasses and rice flour. This research was conducted at the Center for Breeding and Development of Oyster Mushroom and Ear Mushroom Cultivation Sunggal District, Deli Serdang Regency. This study used a factorial completely randomized design (RAL) consisting of 2 treatment factors, 16 treatments, 2 replications and 32 baglogs. The first factor is the concentration of molasses with M0: (control), M1: 7.5 ml/20 ml, M2: 15.0 ml/20 ml, M3: 22.5 ml/20 ml and the second factor is the administration of Rice Flour with a concentration of T0: (control), T1: 20 gr/20 ml, T2: 40 gr/20 ml, T3: 60 gr/20ml. Parameters observed were mycelium growth rate (cm), stalk height (cm), hood diameter (cm), hood thickness (mm), number of branches/clumps, and wet weight (g). The rice flour treatment 12 days after inoculation showed significantly different results with the highest data T0: 10.13cm and the lowest data T3: 8.00cm. The highest data was T0:14.85cm and the lowest data was T3: 12.36cm after 18 days after inoculation. The highest parameter of plant height was M0: 20.13cm and the highest data of rice flour treatment was T2: 19.13 cm. The hood diameter parameter showed the highest data was M2: 43.90cm and the highest rice flour treatment data was T2: 2.64cm. The highest data hood thickness parameters are M2: 29.09mm and T2: 29.98 mm. parameters of the highest number of data branches M0: 88.75 branches and T1: 86.25 branches. The highest data wet weight parameter was M0: 88.75 grams and the highest data was given to rice flour at T1: 86.25 grams

Abstract

Low self-confidence is one of the problems faced by students in the learning process, so that the teacher's efforts are needed to facilitate the improvement of character building in students. This study aims to determine the effect of the SAVI (Somatic, Auditory, Visualization, and Intellectuality) learning model in increasing elementary-aged students' self-confidence. This research was conducted in class VII MTs Yaspend Muslim, with a sample of class VII-3 students. Data analysis used a type of regression analysis. The results of this study found that the effect of the SAVI model on student character building was in the good category, with the Fcount regression test of 37.59 and Ftable of 4.18. Thus, it can be concluded that the SAVI learning model (Somatic, Auditory, Visualization, and Intellectualy) has a positive effect on students' Character Building, because this learning model involves all students' sensory modalities so that students become active.

Abstract

Al-Qur'an is primary literacy for Muslims, including elementary age children. Likewise, for mentally retarded children the ability to read the Koran still leaves its own problems. This study aims to describe efforts to improve the ability to read the letters of the Qur'an for children with mild mental retardation through the bil hikmah method. The setting of this research was in Class VII C of the Batubara State SLB, where in this class there were three mild mentally retarded children with the initials MRF, ZM and K with different characteristics. The research will be conducted using classroom action research methods. This research was conducted in collaboration with teachers. This research was conducted in 2 cycles. Each cycle starts from the stages of planning, implementing actions, observing and reflecting. The results of the research are described in narrative and graphical form from the process to the improvement results in cycle II. In the first cycle the children obtained MRF and ZM results of 65% and K 60% and the results in the second cycle of MRF, ZM and K were 85%. This shows that the bil Hikmah method is effectively used to improve the ability to read Al-Quran letters for children with mild mental retardation.

Abstract

Work engagement and organizational commitment are research concepts that still need to be studied in Indonesia. Millennial employees are the generation that is dominating almost all organizations in Indonesia. The study aimed to examine how the role of authentic leadership is on work engagement and organizational commitment for millennial employees. Data were collected from 171 millennial employees in private and start-up companies through online and offline surveys. The quantitative method by survey method was applied in this study. Three scales were used to collect data, including the Utrecht Work Engagement Scale of work engagement (17 items), Organizational Commitment Questionnaire (15 items), and Authentic Leadership Questionnaire (24 items). The data analysis used multivariate analysis of covariance (MANCOVA). Results showed authentic leadership has a positive role in work engagement and organizational commitment, so the research hypothesis is accepted. This study further clarifies the contribution of authentic leadership in generating high work engagement and organizational commitment of the millennial generation. By applying authentic leadership, the leader may enhance millennial employees' work engagement and organizational commitment.

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

A website is now a destination for crucial information in the contemporary digital era. Among the necessary educational resources for any school or institution are libraries. Because knowledge and information can be readily found by students at the library. People believe that as technology advances, they can operate more productively and successfully. Converting an analog system to an electronic one is one of them. By using the website Libraries that have internet access can operate more effectively and efficiently in carrying out bookkeeping. In this research, a web-based information system was designed using the PHP (Hypertext Preprocessor) programming language. The linear sequential research method was chosen because it is very suitable for projects with clear needs and limited resources and time. By creating It is hoped that this approach will be able to solve a number of issues. the need to look for books and facilitate the distribution of book loans and report writing for the school administration. Based on the findings of the conducted research, the author incorporated the study's findings into the creation of an online library information system SMKN 5 Pekanbaru library.

Abstract

Klasifikasi penyakit mata merupakan aspek penting dalam deteksi dini dan pengobatan berbagai penyakit mata. Dalam penelitian ini, kami mengusulkan model klasifikasi berbasis Support Vector Machine (1) untuk mengidentifikasi jenis penyakit mata secara lebih akurat. SVM dipilih karena memiliki kemampuan diferensiasi kelas tinggi dengan margin maksimal, terutama untuk data berdimensi besar dan kompleksitas variabel tinggi. Dataset yang digunakan berisi gambar mata dari berbagai kategori penyakit seperti katarak (2), glaukoma (3), dan retinopati diabetik (4). Setelah prapemrosesan dan ekstraksi fitur, model SVM dilatih dan diuji menggunakan pendekatan validasi silang (5) untuk mengevaluasi kinerjanya dalam hal akurasi, sensitivitas, dan spesifisitas. Hasil penelitian menunjukkan bahwa model SVM dapat mencapai akurasi tinggi dalam klasifikasi penyakit mata, sehingga memiliki potensi besar untuk diterapkan pada sistem pendukung diagnostik berbantuan komputer di masa depan.
