Abstract

This study endeavors to enhance the productivity of solar module production in a renewable energy conversion company. The existing production line needs help in achieving the daily target of 64 units, resulting in an actual output of only 40 units. This study focuses on optimizing the production line by considering processing time adjustments and operator flexibility. To accurately measure working time, we incorporate operator flexibility and adjustment factors in the planning phase of solar module production. The primary objective is establishing an optimal production trajectory by balancing the load and capacity across workstations, thereby elevating overall production efficiency. The approach involves the application of the trial-error method and the shortest operation time method, implemented through POM QM software. Through meticulous data analysis, we determine that the trial-error process yields the most optimal results. Post-implementation, improvements are evident as the solar module production capacity increases to 60 units per day from the initial 40 units. Additionally, the idle time ratio on the assembly line to available time diminishes to 13.17% after optimization. This study contributes valuable insights into the effective enhancement of solar module production lines, emphasizing practical methodologies and software-assisted techniques for achieving substantial productivity gains in the renewable energy sector.

Abstract

Peatlands have good prospects for use as agricultural land. Peatlands have many problems, one of which is high acidity. Organic goat manure is expected to be able to overcome the problem of peatlands. Therefore, this study aimed to determine the best combination of peat media and organic goat manure on the pH of the media and the growth of pepper plant stem cuttings. This research was carried out for three months (October to December 2021), including taking peat soil in Sukamaju Village, Landasan Ulin Timur District, Banjarbaru, South Kalimantan; taking pepper cuttings in Senakin Village, Kotabaru Regency, South Kalimantan; planting pepper cuttings in the Greenhouse Department of Agroecotechnology Faculty Agriculture at Lambung Mangkurat University, Banjarbaru, South Kalimantan; and observing the pH of cutting media at the Production Laboratory of the Agroecotechnology Department, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru, South Kalimantan. This research used a completely randomized design (CRD) with one factor. The factor studied was the composition of the planting medium (K), which consisted of five treatments: k1 = 100% peat + 0% organic goat manure, k2 = 75% peat + 25% organic goat manure, k3 = 50% peat + 50% organic goat manure, k4 = 25% peat + 75% goat manure organic fertilizer, and k5 = 0% peat + 100% goat manure organic fertilizer. The results showed that the treatment with the composition of 0% peat + 100% organic goat manure (k5) is the best for increasing the pH of the media (6.50). The composition of 50% peat + 50% organic goat manure (k3) was the best in increasing shoot height and number of leaves (4.44 cm shoot height and 1.08 leaves), but not different from the composition of 25% peat + 75% organic fertilizer goat manure (k4) on the percentage of live cuttings, number of shoots, and leaf width (70% live cuttings, 0.70 shoots, and 2.69 cm leaf width).

Abstract

This study evaluates the inclusive education practices for children with special needs (CSN) at Hayat School, focusing on the integration of Islamic values in educational management. The main objective of this study is to create a fair and inclusive learning environment that accommodates all students without discrimination. A qualitative approach was used in this research, involving interviews, observations, and document analysis to gain an in-depth understanding of the implementation of inclusive education. The findings indicate that challenges in managing inclusive classrooms include the need to stabilize the emotions of students with diverse needs. Teachers face difficulties in maintaining student engagement due to the unstable mood changes of CSN students. Therefore, adopting teaching methods and maintaining a continuous focus are crucial for fostering an inclusive atmosphere. In the student assessment system, Hayat School implements tailored examination methods for CSN, supporting inclusivity in the evaluation process. In conclusion, inclusive educational management requires ongoing professional development for educators, with teaching strategies that enhance empathy and understanding among regular students toward their peers with special needs. These efforts are essential to ensure that CSN develop academically and socially alongside their peers in an inclusive environment.

Abstract

Kurikulum Merdeka memberikan peluang bagi lembaga pendidikan untuk mengintegrasikan nilai-nilai agama, termasuk nilai tauhid, sebagai landasan pembentukan karakter Islami siswa. Penelitian ini bertujuan untuk mengevaluasi efektivitas integrasi nilai-nilai tauhid dalam Kurikulum Merdeka sebagai dasar pembentukan karakter Islami siswa di SD IT Attaqwa Nurul Fahmi. Penelitian ini mengisi celah dalam literatur sebelumnya yang cenderung membahas aspek implementasi normatif, tanpa mengevaluasi secara sistematis dampaknya terhadap karakter siswa. Pendekatan kualitatif digunakan dengan teknik triangulasi melalui wawancara, observasi, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa integrasi nilai tauhid, yang mencakup aspek keimanan, ketakwaan, dan akhlak mulia, telah diterapkan secara sangat baik dengan skor rata-rata 4.51. Keberhasilan ini ditopang oleh pembiasaan ibadah, materi ajar terstruktur, dan dukungan manajemen sekolah. Namun, tantangan tetap ada, terutama dalam ketidakseimbangan penguatan nilai di rumah. Penelitian ini merekomendasikan sinergi antara sekolah dan keluarga melalui pelatihan parenting Islami, panduan pendidikan karakter berbasis rumah, serta forum komunikasi berkala. Temuan ini memberikan kontribusi praktis bagi institusi pendidikan dasar lainnya dalam mengadopsi model pendidikan karakter Islami berbasis tauhid secara lebih terpadu dan berkelanjutan.

Abstract

This study aimed to investigate the implementation of multimodal tools to teach English in kindergarten. The recent study found that it was challenging to teach English as a foreign language for young learners; so that, teachers should provide various activities and improve creativity in teaching. In contrast, from my general observations, drilling was the only method practiced by the teachers to teach English. Nevertheless, this method was not quite fun and engaging for a long term. As the alternative, to overcome the problem, teacher was able to use multimodality to conduct English lesson especially in kindergarten. This research used qualitative descriptive design. The data were collected by interview with verbatim data technique and observation. The investigation showed that English teacher at RA Nurul Falah used several media and activities. These were audio-visual media; which were laptop, flashcard, speaker active and audio media; which was handphone. Besides that, teacher used some techniques. These were learning while playing; learning through running and other movement; learning with watching videos; learning by using with flash cards and learning ask and answer questions to improve their critical thinking. The study showed that the implementation of multimodality could attract and enhanced students’ engagement in the class. Students seemed more fun with many tools usage rather than only implementing drilling method in the class. Moreover, the research also revealed that multimodal usage was better than drilling. It also concluded that the multimodality use in teaching English lessons was useful and beneficial.

Abstract

This study examines the relationship between the socioeconomic status (SES) of tenth-grade students at SMA Negeri 4 Praya and their final physics exam scores for the 2022/2023 academic year. SES indicators include parents' income and education level, collected via qualitative questionnaires and quantitative assessment of physics exam scores. Random Forest Regression and Neural Network techniques were used for analysis. The results showed no significant relationship between SES and physics scores. For parents' education level, Neural Network Regression yielded a Mean Squared Error (MSE) of 323.78 and an R² score of -0.0129, while Random Forest Regression produced an MSE of 327.08 and an R² score of -0.0232. Similarly, for parents' income, Random Forest Regression resulted in an MSE of 327.08 and an R² score of -0.0232, and Neural Network Regression yielded an MSE of 323.78 and an R² score of -0.0129. These negative R² scores indicate that SES does not significantly impact physics exam scores, highlighting the complexity of factors influencing academic performance. This research suggests that other variables may play a more critical role in determining students' success in physics. This research underscores the need for a more comprehensive approach to understanding and supporting student achievement in education.
