Authors: Nur Irwan
Published: June 2022

Permasalahan yang penting untuk diperhatikan adalah bukan terbatas pada keunikan komunitas To Balo karena memiliki keadaan fisik dan penggunaan bahasa yang berbeda jauh dari masyarakat Sulawesi Selatan pada khususnya dan Indonesia pada umumnya, tetapi wilayah domisili mereka merupakan daerah yang sulit dijangkau, jauh dari sarana dan prasarana publik seperti balai kesehatan, sekolah, menyebabkan kondisi ekonominya untuk kelangsungan hidup anggota keluarga cukup memprihatinkan, dan terus menciptakan citra sosial “terasing” bagi komunitas tersebut. Tujuan penelitian ini adalah (i) Mengungkap persepsi masyarakat terhadap pencitraan To Balo sebagai komunitas terasing dalam hubungan interaksi sosialnnya (ii) Mengemukakan upaya-upaya yang dilakukan To Balo dalam mempertahankan eksistensi keberadaan komunitasnya di Desa Bulo-Bulo Kabupaten Barru, dan (iii) Mendeskripsikan berbagai faktor yang mendeterminasi keterasingan komunitas To Balo di Desa Bulo-Bulo Kabupaten Barru. Penelitian ini merupakan penelitian kualitatif dengan pendekatan dialektis interpretatif dengan menggunakan teknik observasi, wawancara, dan kajian retrospektif. Hasil penelitian menunjukkan bahwa (i) dalam lingkaran dominasi budaya Bugis dan latar sejarah keberadaan To Balo sebagai akibat dari adanya hubungan terlarang seorang wanita petani dengan hewan di masa lampau mendorong masyarakat mencitrakan negatif komunitas tersebut, termasuk adanya belang disekujur tubuhnya sebagai penciri khusus To Balo yang berbeda dengan orang kebanyakan (ii) upaya mempertahankan eksistensi keberadaan komunitas To Balo dilakukan melalui jalinan relasi sosial dalam pertalian perkawinan dengan anggota masyarakat non To Balo, dan (iii) keterbukaan sosial To Balo dalam interaksi sosial masih terhalang oleh citra negatif masyarakat luas akibat latar sejarah keberadaannya.Kata kunci: konstruksi sosial, komunitas To Balo, Masyarakat Terasing

Therefore it is necessary to research the relationship of mastery of theory assisted modules with student practice competencies. This type of research uses correlational study methods. Correlational research is research used to see the relationship between one variable with another variable. From the results of normality testing data processing, the significance value of variable x (mastery of theory) = 0.664> alpha = 0.05 and the significance value of variable y (practice competency) = 0.794> alpha = 0.05, so the data is said to be normally distributed. For the linearity test, the significance value of deviation from linearity is obtained = 0.221> 0.05, so that the variables x and y are said to be linear. Hypothesis testing obtained the correlation coefficient value of 0.767. The price of rtable n 20 = 0.444 with a significant level of 5% so the price of rcount> rtable, meaning that there is a relationship between the mastery of the theory of the installation of electrical aids assisted in modules with the practical competence of students in class XI TITL at SMK Negeri 1 Pariaman.

Motorcycle pedicab is one of the land transportation vehicles that are still widely used by the community, especially for short distances. One of the disadvantages of using a motorcycle pedicab for transportation is the unavailability of standard fare for passengers. In this paper, a taximeter is proposed to determine motorcycle pedicab rates based on distance traveled. The taximeter display in the form of mileage and rate is designed using the Android application and Arduino Uno as data processing. This device is equipped with a hall effect sensor as a reader of wheel rotation and a bluetooth module as the interface between Android and Arduino. In addition, the Android screen also provides a start and stop button to start or stop the calculation of the meter. The experimental results show that this devices have worked in accordance with the objectives, where the android screen has been able to display distance data and pedicab rates according to mileage.

Indonesia's education system separates vocational education from academic education. Vocational education, which was previously not a key focus for prospective students, should now be on par with academic education at both the secondary and higher education levels. However, research on Vocational Education in Indonesia is still limited, particularly articles in reliable indexed databases; therefore, research on Vocational Education in Indonesia is still readily available. This research aims to map studies in bibliometrics connected to research trends in Vocational Education in Indonesia. This study does a statistical analysis of the number of publications on "Pendidikan Vokasi" in Bahasa during the previous five years. The Dimensions database is used for the study dataset, which is processed using Bibliometrix utilizing R-Tool and displayed with Vosviewer. The bibliometric study of the "Pendidikan Vokasi" research resulted in 2500 articles crawling in journals or proceedings on the Dimensions database. A. Ambiyar, N. Jalinus, and N. Erizon. Three names are incredibly fruitful in terms of creating research in this sector. At the same time, Padang State University has the most links to the issue. According to the findings of the bibliometric investigation, the Jurnal Pendidikan Vokasi is the leading generator of publications on the topic. Bibliometric mapping of the study subject "Pendidikan Vokasi" using the VOSviewer, on the other hand, discovered that trend research exclusively mentioned schools (SMK) and learning techniques or models. During this period, there was little research on the industry.
