Abstract

Indonesian local wisdom-based learning still needs to be improved, such as Pacu Jalur. This is useful for introducing the nation's culture to students, so they are not forgotten. However, learning local wisdom must also be integrated with technology-based learning so that it remains in line with current developments. The purpose of this research is to develop students' worksheets for Game-based PBL models integrated with Local Wisdom Pacu Jalur in physics learning. The topic chosen in this study is Bouyance Force. The method in this study uses the 4D model, namely Define, Design, Develop, and Disseminate. The developed students' worksheets have been validated by three physics education lecturers. The research results obtained are aspects of content eligibility 85 (decent), presentation 90 (very feasible), appearance 88 (very feasible), and language 89 very feasible. Based on these findings, it can be concluded that the students' worksheets developed are feasible and ready to be implemented in physics learning on the topic of bouyance force. The recommendation for further research is to test students' worksheets in large-scale learning in physics classes.

Abstract

Implementing a healthy lifestyle plays a crucial role in preventing stunting, particularly among children and pregnant women. Additionally, economic factors, such as low per capita family income (below the poverty line), can also contribute to the occurrence of stunting. The objective of the Community Partnership Service (PKM) program in Pananggahan Village, Sorkam District, Central Tapanuli Regency, with the theme 'Implementing a Healthy Lifestyle to Prevent Stunting: Healthy Children, Strong and Happy Families,' is to: (1) Support Optimal Growth: A healthy lifestyle, including balanced nutrition, plays a key role in ensuring that children receive the essential vitamins and minerals needed to support optimal physical growth and brain development. (2) Strengthen the Immune System: Healthy food, physical activity, and good hygiene practices help strengthen children's immune systems, making them less prone to infections. Recurrent infections can exacerbate the risk of stunting, as the body struggles to absorb nutrients effectively. (3) Prevent Nutrient Deficiencies: A healthy lifestyle encourages the consumption of nutritious foods in adequate amounts, preventing deficiencies in essential micronutrients such as iron, calcium, vitamin A, and zinc. Long-term nutrient deficiencies are a primary cause of stunting. With a proper healthy lifestyle, the risk of stunting can be reduced, as children receive the support necessary for growth and development in line with their full potential.

Abstract

Analysis of Effective Communication on Employee Performance Improvement at PT. Kencana Mulia Abadi Sibolga. Performance improvement can be achieved through the implementation of effective communication. This study aims to analyze the impact of effective communication on employee performance improvement at PT. Kencana Mulia Abadi Sibolga. The population in this study consists of all employees of PT. Kencana Mulia Abadi Sibolga, totaling 31 individuals, who were also used as the research sample. Based on the research findings, there is a positive relationship between effective communication and employee performance improvement at PT. Kencana Mulia Abadi Sibolga. This is evidenced by the increase in the number of consumers over the past five years, totaling 310 individuals. The study results indicate a positive correlation between effective communication and employee performance at PT. Kencana Mulia Abadi Sibolga, with a correlation coefficient of 0.757, which, when interpreted on a scale, falls into the moderate category. The regression equation obtained is: Y = 12.491 + 0.637X, which demonstrates the influence of effective communication on employee performance. The t-test results show that the proposed hypothesis is accepted, as t-calculated (6.241) > t-table (2.0452). This means that employee performance increases by the regression coefficient/slope (0.573) for every unit increase in the effective communication variable. Meanwhile, the coefficient of determination reveals that effective communication contributes only 57.3% to employee performance at PT. Kencana Mulia Abadi Sibolga, while the remaining 42.7% is influenced by other factors not examined in this study.

Abstract

Dari beberapa observasi langsung di lapangan, menunjukkan minat usaha masyarakat Kabupaten Tapanuli Tengah masih tergolong rendah, hal tersebut dapat dilihat masih sedikitnya hasil kreasi masyarakat yang meramaikan lalu lintas barang, padahal Kabupaten Tapanuli Tengah adalah daerah pesisir yang kaya akan hasil laut dan daerah pariwisata dengan mengandalkan keindahan daerah pantai. Masih minimnya produksi olahan dari hasil laut dan banyak cendramata yang diperkenalkan pada. Masih banyaknya anak muda yang kurang peduli terhadap peluang-peluang usaha dengan potensi daerah memanfaatkan teknologi untuk mengenalkan ke luar daerah. Adapun tujuan yang ingin dicapai dalam kegiatan Pengabdian kepada Masyarakat ini adalah menumbuhkan minat berwirausaha kaula muda yang sudah ada bekal pendidikan untuk memamfaatkan  peluang sarana digital di Kelurahan Binasi, Kabupaten Tapanuli Tengah. Kegiatan sosialisasi “Meningkatkan Minat Generasi Muda Untuk Meningkatkan UMKM di Kelurahan Binasi Kabupaten Tapanuli Tengah” dilaksanakan di gedung Madrasah di Kelurahan Binasi, Kecamatan Sorkam Barat, Kabupaten Tapanuli Tengah pada hari Kamis, Tanggal 09 Februari 2023. Kegiatan terlaksana sesuai dengan tujuan dan rencana. Kegiatan ini mendapat sambutan yang baik dari masyarakat yaitu  anak muda dan Pemerintah daerah setempat, yaitu Lurah dan Kepling. Kegiatan ini dapat memberikan tambahan semangat dan pengetahuan tentang peluang usaha dengan peluang di era digital saat ini.Kata Kunci : Minat; Generasi Muda; Meningkatkan; UMKM

Abstract

This study aims to describe students’ character value and reveal the relationship of character values in elementary school children based on gender, grade and type of the school. The character values analyzed include religion, nationalism, integrity, independence, and cooperative values. This research was a quantitative method with a cross-sectional design by explaining and analyzing the results using Jeffrey’s amazing statistics program (JASP) software and students’ character values was categorized and described according to the aspect, gender, grade, and type of the school. Character of elementary school children (CESC) questionnaire was used as an instrument in this study. CESC have very good internal consistency (0.80 to 0.87) and have suitability construct model. The respondent of this study was 862 students obtained through the stratified random sampling randomly technique in elementary school at Yogyakarta Province. The result of this study confirmed that the students’ character value is a high level. The lowest aspect is integrity (2.40), while the highest aspect is religious (3.16). There is a relationship between the character values: religion, nationalism, integrity, independent, and cooperative values. It indicates that policymakers or teachers should improve students’ character value by training or applying a learning model that focuses explicitly on students’ character.

Abstract

The test of critical thinking skills in specific topics in physics is still rarely. This study aimed to develop a specific test in critical thinking skills in the kinetic theory of gases (CTKTG) and also to assess the students' critical thinking skills. This study used the 4D method (Define, Design, Develop, and Disseminate). The CTKTG test was initially tested in four sample groups: interviews with an expert review (N = 3), professional physics teachers (N = 2), and graduate school students (N = 2), students from secondary schools (N = 29). The test was modified based on the revised results in the initial test. After that, the test was given to a group of students in class XI, who were science students (N = 55). The results showed that internal consistency from the CTKTG test was α = .89 (good). The implementation strategies and tactics are the most difficult aspect of critical thinking skill with a mean of 1.37 (very low) and basic classification is easiest with a mean of 2.84 (average). So, the findings showed that the CTKTG test can be used to measure students' critical thinking skills on the topic of the kinetic theory of gases.
