Abstract

Program Indonesia Pintar (PIP) adalah inisiatif bantuan sosial yang diperkenalkan oleh pemerintah Indonesia untuk membantu siswa dari keluarga yang tidak mampu agar dapat melanjutkan pendidikan mereka tanpa kesulitan keuangan. Untuk memperoleh PIP, calon penerima bantuan harus termasuk dalam kategori layak sebagai penerima bantuan. Penelitian ini bertujuan untuk menentukan kelayakan penerima bantuan PIP di SDN 064999 Medan menggunakan algoritma C4.5 yang mana digunakan dalam membentuk pohon keputusan. Dalam penelitian ini, data yang digunakan adalah data siswa SDN 064999 Medan yang telah menerima bantuan PIP pada tahun 2023. Hasil penelitian menunjukkan bahwa algoritma C4.5 membentuk pohon keputusan yang baik untuk memprediksi kelayakan penerima bantuan PIP. Pohon keputusan tersebut menunjukkan bahwa atribut yang paling penting untuk memprediksi kelayakan penerima bantuan PIP adalah atribut pendapatan orangtua, status pekerjaan orangtua, dan jumlah tanggungan orangtua. Dari penelitian ini juga diperoleh 10 rules / aturan dalam penentuan kelayakan penerima bantuan PIP dengan algoritma C4.5. Hasil penelitian ini dapat digunakan untuk membantu dalam proses seleksi penerima bantuan PIP dan untuk memastikan bahwa bantuan tersebut tepat sasaran.

Abstract

Porang tubers are one of the foodstuffs rich in glucomannan content. Glucomannan is widely used in various industrial fields, one of which is pharmaceuticals. To produce pure glucomannan compounds, the method of isolating glucomannan using a two-phase water system (ATPS) solvent has been widely used. One option is isolation with a two-phase water system (ATPS) of inorganic salts ammonium sulfate and ethanol at various concentrations. This study focuses on optimizing the concentration ratio of ammonium sulfate and ethanol for the glucomannan extraction process, carried out with a factorial design and continued analysis with a response surface methodology (RSM) approach. The results of the experimental design at the composition of ammonium sulfate concentration of 17.07% w/w and ethanol of 27.07% w/w showed optimal dry extract acquisition in the two-phase water system (ATPS), with a yield of 81.07%. Characterization of the results of porang flour extract with FTIR produced stretching vibrations of the O-H group at 3427.51 cm-1 and C-O-C (glycosidic bond) at 1020.34 cm-1 and bending vibrations of the -CH functional group at 864.11 cm-1, which are specific values ​​for glucomannan compounds and using visible spectrophotometry, the glucomannan concentration was obtained at 32.67%.

Abstract

Pelaksanan pendidikan di sekolah menengah atas tidak terlepas dari terjadinya pelanggaran-pelanggaran yang dilakukan oleh siswa. Pencataan pelanggaran siswa yang dilakukan secara manual selain tidak praktis juga sulit untuk ditelusuri rekam jejaknya. Agar pencataan pelanggaran siswa tersebut dapat  dilaksanakan lebih mudah dan menelusuran rekam jejak pelanggaran lebih efisien perlu dikembangkan sistem pencataan pelanggaran siswa berbasis web, sehingga dapat membantu sekolah dalam melakukan tindakan selanjutnya. Di dalam makalah ini, sistem pencataan pelanggaran siswa dirancang untuk Sekolah Menengah Atas Negeri 1 Kuala Pembuang. Penerapan sistem ini di sekolah melibatkan admin, kepala sekolah dan guru. Admin bertanggung jawab dalam mengelola sistem berupa tindakan menambah, mengubah, menghapus data kategori pelanggaran, daftar pelanggaran, kategori kebaikan, daftar kebaikan, data guru, data kelas, data siswa dan data pengguna. User  Guru BK hanya memiliki kewenangan mengelola data daftar pelanggaran, daftar kebaikan dan daftar siswa, sedangkan  Kepala Sekolah hanya dapat mengakses dan mencetak data.

Abstract

Training and competency certification are part of efforts to enhance the quality of human resources, particularly vocational lecturers, in mastering best practices in Preventive and Predictive Maintenance. This program was conducted over a period of twelve (12) days and covered both theoretical and practical aspects of Preventive and Predictive Maintenance, including Maintenance Planning & Scheduling, Vibration Analysis, Thermography, and Total Productive Maintenance. The training was organized through a collaboration between the Ministry of Education, Culture, Research and Technology, the Indonesia Endowment Fund for Education (LPDP), and the Indonesian Society of Reliability (ISR). The main objective of this program was to improve lecturers' competencies in Reliability-Centered Maintenance (RCM), Overall Equipment Effectiveness (OEE), failure analysis using methods such as Failure Mode and Effects Analysis (FMEA), Root Cause Analysis (RCA), Root Cause Failure Analysis (RCFA), and Supply Chain Management (SCM). As a result of the training and certification program, all eleven (11) participants were declared certified and received certification from ISR. This achievement serves as capital to support excellent and globally competitive vocational education.

Abstract

Lebakaso Hamlet, Cikahuripan Village, Cimanggung District, Sumedang Regency, is a hamlet that requires attention in increasing livestock management capacity. The community already has a village organization, the Pasir Sela Forest Farmers Group (KTH), to improve livestock management. A green fodder chopper machine and machine maintenance operation training are needed. The purpose of the Community Service program contract activity is to improve the quality of partners and provide training, implementation methods for problem identification activities, preparing machine designs, machine procurement and manufacture, providing machine operation and maintenance training, and machine handover and activity reporting. The results of the activity have been realized according to plan based on the implementation method of the availability of a chopper machine that has an electric motor drive, is capable of chopping stems and grass, has a filter feature, and speed variations with a choice of pulley sizes and machine construction that can be easily mobilized. The implementation of operation and maintenance training and handover of the chopper machine tool was successfully carried out with PkM KTH Pasir Sela partners. Furthermore, to ensure the allocation of the machine and its utilization, monitoring and evaluation are carried out.

Abstract

Story telling is one method of speaking in the form of telling activities or telling about an event, and is delivered orally which aims to share stories with others and become a method that can be used in fabel’s learning. Retelling the fable text from read or heard is one of the basic competencies that students are expected to be able to do optimally. The purpose of this research is to reconstruct the story telling method with the help of visual aids in class VII SMP Al-Hidayah Medan. This research was conducted by analyzing (1) the conditions of the application of the story telling method (2) the impact of creative teaching aids. The method used in this research is descriptive qualitative method. Data collection techniques in research were conducted by interviews and literature study. The results showed that the application of the method in learning to retell fable texts in grade VII of Al-Hidayah Junior High School still did not get optimal results and responses both in terms of student response, speaking skills, and the absence of media support, so there is a need for reconstruction to achieve better learning outcomes and student responses.
