Abstract
This study aims to test the application of the reaction time test training method to improve visual reaction speed in Persik Kendal soccer athletes. Visual speed is a key factor in making quick decisions on the soccer field, such as reacting to the movement of the ball or opponents. The method used in this study is an experiment with a pre-test and post-test design. Before following the training program, the visual reaction time of athletes was measured using a react time test involving visual stimuli in the form of light or object movement that must be responded to immediately. The training program was carried out for four weeks with variations in speed and type of visual stimulus, aiming to improve athletes' ability to respond to stimuli more quickly. After the training program was completed, a post-test was conducted to measure changes in athletes' reaction time. The data obtained were analyzed using a t-test to compare the difference in reaction time before and after training. The results showed a significant increase in the visual reaction speed of Persik Kendal soccer athletes after undergoing this training program. The expected increase in visual reaction time can have an impact on improving performance on the field, especially in terms of making quick and accurate decision
Pemanfaatan Karbon Aktif Berbasis Biomassa Lokal sebagai Material Elektroda Superkapasitor: Review
Get PDFPemanfaatan karbon aktif berbasis biomassa lokal sebagai bahan elektroda superkapasitor menawarkan alternatif berkelanjutan dalam teknologi penyimpanan energi. Artikel ini menyajikan tinjauan sistematis terhadap karakteristik fisik dan elektrokimia dari karbon aktif yang disintesis dari berbagai biomassa lokal, antara lain tandan kosong kelapa sawit (TKS), ampas biji kopi robusta, kulit durian, kulit pisang, sekam padi, dan batang jagung. Studi ini menganalisis data luas permukaan spesifik (BET), struktur pori, jenis aktivator kimia, serta performa kapasitansi dari masing-masing material. Hasil menunjukkan bahwa karbon dari ampas biji kopi dan TKS memiliki kinerja terbaik dengan kapasitansi spesifik masing-masing 130 F/g dan 107,83 F/g. Meskipun luas permukaan tinggi merupakan faktor penting, hasil juga menunjukkan bahwa distribusi pori, dominasi mikropori/mesopori, dan jenis aktivator kimia memiliki pengaruh yang signifikan terhadap performa elektroda. Oleh karena itu, pendekatan sintesis yang mempertimbangkan keseimbangan struktur pori dan aktivasi kimia menjadi strategi penting dalam optimalisasi material elektroda superkapasitor berbasis biomassa

A Panel Data Spatial Regression Approach for Modeling Poverty Data In Southern Sumatra
Get PDFThis research examines the use of spatial panel data regression approach to model poverty data in the Southern Sumatra region. The main objective of the study is to model poverty in the Southern Sumatra region using spatial panel data regression. Panel data from districts/cities in South Sumatra, Jambi, Lampung, Bengkulu, and Bangka Belitung during the 2015-2021 period were used in the analysis. The spatial panel models used in this study are panel SAR regression and panel SEM. The results show that the spatial panel data approach is better at explaining variations in poverty levels compared to non-spatial models. A significant spatial spillover effect was found, where the poverty level of an area is influenced by the conditions of its neighboring areas. The results of the analysis show that the best model to use in modeling the Poverty Percentage data in the Southern Sumatra region is the Spatial Autoregressive Fixed Effect (SAR-FE) model based on the smallest AIC and BIC values. Factors such as average years of schooling and life expectancy are proven to have a significant influence on the percentage of poverty in the SAR Fixed Effect model

No full textThe aim of this research is to analyze the effect of science learning using the Discovery Learning model assisted by audio-visual media on factual and conceptual knowledge. The type of research used is quasi-experimental research using a pretest-posttest control group design. The type of data used is quantitative data, namely using question instruments and expert validation sheets. Based on the results of the hypothesis test, it was found that the application of science learning using the Discovery Learning model assisted by audio-visual media had a significant effect on factual and conceptual knowledge. The N-Gain test on the factual knowledge of the experimental class was 93% in the effective category, while in the control class it was 34% in the ineffective category. Knowledge of the concept of the N-Gain test in the experimental class was 86% in the effective category and 26% in the control class in the ineffective category. The correlation test shows there is no significant relationship between factual and conceptual knowledge. The application of science learning using the Discovery Learning model assisted by audio-visual learning media has a significant effect on context knowledge. This is demonstrated by the posttest average of conceptual knowledge in the control class being 54. Meanwhile for the experimental class the average result is 91. Furthermore, there is no relationship between the dimensions of factual knowledge and conceptual knowledge in science learning using the Discovery Learning model assisted by audio-visual media.ABSTRACT

Technology Transfer of Compost Briquette Production from Household Organic Waste in Sawah Lebar Baru Sub-District: Alih teknologi pembuatan briket kompos dari limbah organik rumah tangga di kelurahan sawah lebar baru
Get PDFCompost produced by economically non-productive residents in Sawah Lebar Baru Subdistrict has remained underutilised, leading to accumulation and limited economic benefit. This community service activity aimed to introduce Seed Briquette Technology as an innovative solution to enhance the value and usability of household compost. The programme involved knowledge dissemination and hands-on training on how to produce seed briquettes using existing compost. The compost was compacted into Soil Blocks—pressed blocks with a central hole—using a manual moulding tool. This tool was introduced and distributed to local residents during a technology transfer session conducted by the Faculty of Engineering in RT 29. The participants responded with strong interest and demonstrated the ability to apply the technique successfully. Community members were able to convert their compost into functional seed briquettes, showcasing both skill development and successful adoption of the technology. As a result, the participants gained valuable technical skills which are expected to support future income generation. The activity highlights the potential of simple, locally adapted technologies to improve waste management and economic empowerment in urban communities.
Kompos yang dihasilkan oleh warga yang secara ekonomi kurang produktif di Kelurahan Sawah Lebar Baru selama ini belum dimanfaatkan secara maksimal, sehingga menyebabkan penumpukan dan manfaat ekonomi yang terbatas. Kegiatan pengabdian masyarakat ini bertujuan untuk memperkenalkan Teknologi Briket Benih sebagai solusi inovatif untuk meningkatkan nilai dan kegunaan kompos rumah tangga. Program ini melibatkan penyuluhan dan pelatihan langsung tentang cara membuat briket benih menggunakan kompos yang ada. Kompos tersebut dipadatkan menjadi Soil Block—blok padat dengan lubang di tengah—menggunakan alat cetak manual. Alat ini diperkenalkan dan diserahkan kepada warga setempat pada sesi alih teknologi yang dilakukan oleh Fakultas Teknik di RT 29.
Para peserta menunjukkan minat yang besar dan berhasil menerapkan teknik ini dengan baik. Warga mampu mengubah kompos mereka menjadi briket benih yang fungsional, yang menunjukkan baik pengembangan keterampilan maupun keberhasilan adopsi teknologi ini. Sebagai hasilnya, para peserta memperoleh keterampilan teknis yang diharapkan dapat mendukung peningkatan pendapatan di masa depan. Kegiatan ini menunjukkan potensi teknologi sederhana yang disesuaikan dengan kondisi lokal untuk meningkatkan pengelolaan sampah dan pemberdayaan ekonomi di komunitas perkotaan
