Abstract

Berkenaan dengan tingkat kestabilan dan kekuatan-kekuatan barang produksi dilihat dari segi penggunaan barang tersebut adalah efek redaman pada konstruksinya. Terutama bila konstruksi barang tersebut menerima beban yang berubah-ubah, beban bolak balik dan beban tiba-tiba. Efek redaman dipengaruhi oleh suatu bahan atau sistem yang bergetar. Pemelihan bahan atau material yang baik untuk suatu produk sangatlah dipengaruhi oleh karakteristik dari bahan tersebut. Kekuatan spesimen untuk semua jenis bahan kayu adalah : - Kayu ulin : 208538 N/m, faktor redaman = 0,008820 - Kayu bayam : 176422 N/m, faktor redaman = 0,008685 - Kayu jati : 132081 N/m, faktor redaman = 0,008361 Dan faktor peredam untuk bahan yang berbeda diperoleh bahwa faktor peredam tersebut terjadi pada bahan kayu ulin

Abstract

The development of teaching modules aligned with the Merdeka curriculum for junior and senior high schools is essential to improving the quality of education. Several studies have highlighted the importance of supporting teachers in creating teaching modules based on the Merdeka curriculum to address the challenges faced by educators who may not fully understand the concepts and techniques required. These studies emphasize the importance of training sessions and workshops to equip teachers with the skills needed to develop effective teaching modules that are aligned with the principles of the Merdeka curriculum. In addition, integrating 21st-century skills into teaching modules is essential to prepare students for the challenges of the modern era. The Merdeka curriculum emphasizes the freedom to design learning experiences that are tailored to students' needs and encourage deeper understanding of the material. It also encourages the use of innovative approaches, such as problem-based learning, to enhance the effectiveness of teaching modules. In addition, mathematics teachers' readiness to implement the Merdeka curriculum was assessed as positive, indicating a willingness to embrace a new educational paradigm. However, challenges remain, such as the need for further support in developing instructional materials that are aligned with the thematic nature of the Merdeka curriculum. The development of teaching modules that are aligned with the Merdeka curriculum is an important aspect of modern education. By providing teachers with the necessary training and resources, schools can ensure that students receive high-quality education that is aligned with the principles of the Merdeka curriculum.

Abstract

This study aimed to analyze the influence of fieldwork, hard skills, and self-efficacy on the work readiness of vocational high school students in the Computer and Network Engineering Program in Gowa Regency, while also addressing the research gap regarding the integration of these three variables into a comprehensive model. This ex post facto study used a quantitative approach. This study was conducted at vocational high schools in Gowa Regency, namely, SMK Negeri 1 Gowa, SMK Negeri 2 Gowa, SMK Negeri 4 Gowa, and SMK Negeri 5 Gowa. The subjects of this study were 389 twelfth-grade TKJ students at vocational high schools in Gowa Regency, with a sample of 197 respondents determined using the Slovin formula with a 5% precision level and proportional random sampling. Data were collected through questionnaires and documentation and then analyzed using descriptive statistics, classical assumptions, simple regression, and multiple regression with the assistance of SPSS 24. The research findings indicate that, in part, the field work practice variable (X1) has a significant effect on work readiness (Y) with a significance value of 0.000 < 0.05 and an effect size of 23.2%; the hard skills variable (X2) has a significant effect on work readiness (Y) with a significance value of 0.000 < 0.05 and an effect size of 34.5%; and the self-efficacy variable (X3) has a significant effect on work readiness (Y) with a significance value of 0.000 < 0.05 and an effect size of 62.5%. Simultaneously, the three variables—field work practice, hard skills, and self-efficacy—significantly influenced work readiness, with a significance value of 0.000 < 0.05 and an effect size of 70.8%, while the remaining 29.2% was influenced by other factors outside this research model. The implications of this study highlight the importance of optimizing internship implementation, strengthening hard skills, and developing self-efficacy in an integrated manner to enhance students’ employability. The originality of this study lies in the integration of these three variables into a single model within the specific context of Computer and Network Engineering, an area that has not yet been extensively studied in this way.

Abstract

This study examines the dynamics of the Bugis diaspora in Penajam Paser Utara Regency from 2002 to 2024, focusing on the formation and roles of social, cultural, economic, and political networks within the region. The migration of the Bugis ethnic group to Penajam Paser Utara has been driven by economic factors, the openness of coastal areas, and strong kinship networks connecting origin and destination regions. This research is motivated by the author’s interest in understanding the socio-economic, political, and cultural networks established by the Bugis diaspora. The study aims to analyze the role of these networks in shaping the economic, political, and socio-cultural life of the Bugis community in Penajam Paser Utara. A descriptive qualitative approach was employed, with data collected through interviews, observations, literature review, and documentation. The findings reveal that the Bugis diaspora has successfully developed strong social networks based on kinship and religious values, which serve as a fundamental foundation for cultural adaptation and local economic development, particularly in the fisheries, trade, and maritime transportation sectors. In the political sphere, the Bugis community actively participates in local governance structures and has become one of the influential ethnic groups in regional political dynamics. The integration of Bugis cultural values with the local social context has produced a distinctive diaspora identity adaptive and open to change, yet firmly maintaining ethnic solidarity and the values of siri’ na pacce as guiding principles of life. In conclusion, the Bugis diaspora in Penajam Paser Utara represents a significant example of how migrant communities build resilient socio-cultural and economic networks in new environments, contributing substantially to sustainable community development.

Abstract

Background: Maritime transportation safety in Indonesia still faces various challenges, marked by a high number of ship accidents and a less-than-optimal vessel traffic monitoring system. The Automatic Identification System (AIS), as a modern navigation technology, has been mandated by the government to improve shipping safety. Objective: This study aims to analyze the effectiveness of the AIS-based monitoring system in improving maritime transportation safety in Indonesia and to identify obstacles in its implementation. Methods: The research used a mixed-methods approach through observations at VTS Makassar, interviews with ship operators and regulators, and distribution of questionnaires to shipping actors. Results: The results showed that AIS plays an important role in increasing navigational awareness, supporting real-time ship traffic monitoring, and aiding search and rescue processes. However, its effectiveness is not yet optimal due to devices being inactive or unfit for use, limited human resource competence, signal interference, and weak regulatory supervision. Conclusion: In conclusion, the AIS system is functionally effective in improving maritime transportation safety but requires regulatory strengthening, improved technical training, and infrastructure updates to ensure its implementation is optimal and sustainable.
