Abstract

This study aims to characterize the effect of superplasticizer addition on local aggregate concrete workability and early-age compressive strength. The methodology involved the use of Portland Composite Cement, local fine and coarse aggregates, and Fosroc Auracast SP310 superplasticizer at dosages of 1%, 1.6%, and 2%. Four concrete mix designs were prepared: normal concrete (BN) and concrete with superplasticizer additions (BN-1%, BN-1.6%, BN-2%). Slump and compressive strength tests were conducted according to Indonesian standards to assess workability and strength at 7 and 14 days. Results indicate that superplasticizer addition significantly improves concrete workability with slump values ranging from 560 to 630 mm compared to 115 mm for the control. Compressive strength also increased markedly, with BN-2% showing the highest strength at 38.56 MPa at 7 days and 51.94 MPa at 14 days. The study concludes that superplasticizer effectively enhances both workability and compressive strength without increasing water demand, resulting in denser and stronger concrete at early curing ages.

Abstract

Konflik Israel dan Palestina merupakan konflik terbesar yang terjadi di abad 21. Di indonesia, konflik ini membentuk sentimen tertentu pada suatu kelompok di kalangan netizen. Hadirnya internet dan media sosial mendorong netizen memiliki kebebasan untuk menyampaikan sentimen sehingga berpotensi menguatkan polaritas di tengah masyarakat. Penelitian ini bertujuan untuk mengambarkan bagaimana netizen di Indonesia merespon konflik Israel dan Palestina. Penelitian ini menggunakan pendekatan text-mining pada komentar video podcast di YouTube. Tahap awal peneliti mengekstrak komentar-komentar dari YouTube. Setelah itu peneliti melakukan pembersihan data melalui preses tokenizing, menghapus kata-kata yang tidak penting (stopwords) dan mengembalikan kata ke dalam bentuk dasar (stemming). Peneliti berhasil mendapatkan sebanyak 209.102 komentar yang sudah dibersihkan. Peneliti melakukan analsisis sentimen menggunakan pendekatan lexicon dari Valence Aware Dictionary and Sentiment Reasoner (VADER). Hasil analisis menunjukkan bahwa sebagian besar komentar netizen memiliki sentimen positif (45.28%). Sedangkan sentimen negatif ada sebanyak 27.72% dan netral sebanyak 27%. Selanjutnya peneliti melakukan analisis topic modelling untuk ke dua komentar yang memiliki sentimen positif dan negatif dengan menggunakan pendekatan laten dirichket allication (LDA). Peneliti menggunakan software Python versi 3.10.11 dengan bantuan modul gensim. Hasil analisis menunjukkan bahwa terdapat enam topik untuk masing-masing komentar yang memiliki sentimen negatif dan positif. Topik untuk komentar yang memiliki sentimen negatif antara lain: Ketidakpahaman narasumber, kerumitan penjelasan narasumber, penyerangan yang dilakukan Israel terhadap Palestina, perebutan wilayah palestina oleh Israel, kelompok pro-Israel di Indonesia dan video YouTube yang bermasalah. Sedangkan untuk komentar yang memiliki sentimen yang positif memiliki topik: Emosional support, harapan untuk rakyat Palestina, pujian untuk narasumber, keingintahuan pada narasumber, kecerdasan narasumber dan berterima kasih kepada podcaster.

Abstract

Individuals frequently seek information and then share that information. The research looks into the dynamics of these two behaviors on the social networking site Facebook. The study included 260 students, the average age of whom was 20. The Information Seeking in Facebook Scale (ISFS) categorizes information seeking behavior on Facebook into five types: social searches, social browsing, hedonic productivity, consumer trends, and general erudition. Meanwhile, students' information-sharing behavior was examined based on the frequency with which they shared information links via the Facebook network in the previous three months. The data obtained was analyzed using logistic regression. As a result, it was discovered that social search and social browsing are important types of information searches to determine the likelihood of someone sharing information. The findings of this study contribute to the flow of searching and sharing information, which can change thought patterns and attitudes and create behavior in the general public, particularly students.

Abstract

The internet has become essential to people of all ages, particularly teenagers, to access information, education, and entertainment. Studying adolescents' well-being has become a hot topic lately, with digital technology and the internet as part of everyday life. The purpose of this study is to examine the role of gender in moderating the relationship between parental and peer relationships with adolescent well-being. Participants in this study were 749 internet user adolescents from various regions in Indonesia, who were selected using convenient sampling techniques. Data was collected online using the EPOCH measure for adolescent well-being, parent-adolescent relationship scales, and friendship quality scales. The results of the hierarchical linear modelling indicate that there is a positive correlation between parent and peer relationships, and adolescent well-being. The findings indicate that the relationship between the two variables is more pronounced among the male population than the female population.

Abstract

This study aims to see how the work ethic of teachers who teach in state schools differs from teachers in private schools at SMA N 2 Lengayang and SMK Technology Lengayang. This study uses quantitative methods with a comparative quantitative design. The population in this study is teachers in state schools and teachers in private schools. The sampling technique in this study used a purposive sampling technique. This study has a sample of 60 teachers with details of 30 samples coming from SMA N 2 Lengayang and 30 samples from SMK Technology Lengayang. The instrument used in this study is the work ethic scale developed by Ngalia (2011) with a total of 27 items. This instrument is based on aspects of the work ethic from Cherrington (1980) which has 3 aspects including: work as a moral obligation, high work discipline, and pride in the results of work. Analysis result using independent sample t-test. The results of the data analysis test show that Ho is rejected and Ha is accepted with a significance value (2-tailed) of 0,048 < 0,05 which means that there is a difference in the work ethic of teachers who teach in state schools and teachers in private schools, where teachers in private schools have a higher work ethic.

Abstract

The use of the internet and digital devices has become an important part of teenagers' daily lives, raising concerns about the increasing phenomenon of online gaming addiction. This study aims to examine the relationship between self-control and online gaming addiction among junior high school students in Padang. This study uses a quantitative approach with a correlational design and involves 125 respondents selected through purposive sampling. Data were collected using the Game Addiction Scale (reliability = 0.851) and the Self-Control Scale (reliability = 0.793). Data analysis was performed using Pearson's product-moment correlation technique with the help of the SPSS 20 for Windows program. The results showed a significant positive correlation between self-control and online game addiction (r = 0.483; p < 0.05). These findings indicate that adolescents with high levels of self-control also show a high tendency toward online gaming behavior, meaning that self-control in the context of adolescence does not always function as a protective factor but can be adaptive to social and digital environmental pressures.
