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

This study aims to find out the students' speaking skills before and after using the Cake Application and the significant difference before and after using the Cake Application on their students' speaking skills. A quantitative method with a pre-experimental design was used in this research. The research was conducted at MAN 1 Karawang which consisted of 25 students as the sample in the tenth-grade class. Pre-test and post-test were part of the six sessions that the research was conducted. The research findings demonstrated that using the Cake Application media significantly improved the students' speaking skills. The pre-test result was 42.24 on average; the maximum score was 68, and the lowest was 32. The average post-test score was 66.72; the top score from the post-test was 100, and the lowest score was 52. In contrast, the speaking scores of the students were higher in the post-test than in the pre-test. In the average N-gain score, it showed that students' speaking skills improved to a medium level of 0,44. Based on research data, using the Cake Application media significantly improved students' speaking skills. The study offers teachers and future researchers as reference materials for using the Cake Applications media in speaking skilss.

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 aims to reveal the impoliteness strategies used by netizens in the comment section of Prabowo Subianto’s inaugural speech as President of the Republic of Indonesia on the BeritaSatu YouTube channel. The background of this research is the growing phenomenon of harsh and impolite comments on social media, particularly in political discourse. This study employs a descriptive qualitative approach using Culpeper’s impoliteness theory within a sociopragmatic framework. The data, consisting of public comments, were analyzed to identify types and strategies of impoliteness, such as bald on record impoliteness, sarcasm and mock impoliteness, negative impoliteness, positive impoliteness, off-record impoliteness. The findings show that netizen comments contain specific patterns of impoliteness that reflect socio-political tensions and ideological expressions in digital space. This research contributes to the expansion of sociopragmatic studies and highlights the urgency of linguistic ethics in digital public communication.
