Abstract

Beton merupakan bahan bangunan yang banyak digunakan dalam konstruksi pembangunan gedung dan perkerasan jalan. Agregat kasar dan agregat halus merupakan 2 komponen yang utama sebagai bahan penyusun beton. Sebagai agregat kasar yang digunakan pada penelitian ini yaitu laterit  serta pasir mahakam yang digunakan sebagai sebagian agregat halus, dengan memanfaatkan laterit yang telah dihancurkan menggunakan stone crusher sebagai material penyusun beton (agregat kasar dan agregat halus) dengan tujuan penelitian untuk mengetahui kuat tekan beton maksimal, mengetahui nilai kuat tekan karakteristik beton, mengetahui proporsi campuran, mengetahui manfaat yang dapat dipergunakan pada campuran beton, mengetahui pola retak pada pengujian kuat tekan beton. Penelitian ini dimulai dengan pengujian terhadap masing-masing bahan penyusun dan membuat rancangan adukan beton berdasarkan metode SNI 03-2834-2000. Mutu beton yang direncanakan 20 Mpa, selanjutnya adalah pembuatan benda uji berbentuk silinder dengan ukuran 150 mm x 300 mm sebanyak 25 benda uji dimana untuk setiap sebanyak 5 benda uji. Pengujian kuat tekan beton dilakukan setelah beton berumur 3, 7, 14, 21 dan 28 hari dievaluasi berdasarkan SNI 03-1974-1990.. Komposisi material campuran adalah (pasir 28%; laterit 1/2 52%; laterit 2/3 20%). Nilai kuat tekan adalah sebesar 20,05 MPa pada umur 28 hari. Nilai kuat tekan karakteristik (f’ck) beton laterit adalah 18,21 MPa Proporsi campuran material beton laterit untuk 1 m3 adalah maka material yang dibutuhkan semen 352,4 Kg; air 178,35 Kg/ltr; pasir mahakam 502,2 Kg; laterit 1/2 892,98 Kg; laterit 2/3 344,72 Kg dan perbandingan adukan beton adalah semen: air: laterit 1/2: laterit 2/3 = 1: 1,42: 2,53: 0,98. Beton laterit dapat dipergunakan untuk membuat beton bertulang seperti pelat lantai dasar, gorong-gorong beton bertulang, bangunan bawah jembatan dan struktur beton tanpa tulangan seperti beton siklop, trotoar dan pasangan batu kosong yang diisi adukan pasangan batu, Hasil pengujian benda uji silinder menunjukkan pola retak yang dominan terjadi adalah shear dan cone and shear

Abstract

Bullying is an act of violence that can cause psychological disorders in someone. Bullying can be done with the aim of hurting someone either verbally, physically or through social media. Currently cases of bullying are rife among students in Indonesia. The impact experienced by victims of bullying can lead to disturbed psychological conditions and physical health complaints. Therefore, this article was created with the aim of adding a sense of social awareness to cases of bullying in the surrounding environment, implementing Pancasila values in actions and behavior, and educating both victims and perpetrators of bullying. The method used in this study is qualitative which is distributed through questionnaires to university students. The results of the study show that among adolescents, especially college students, cases of bullying are still very high, victims of acts of bullying will experience psychological pressure which affects the mental health of victims. This condition can cause high levels of anxiety, depression and decreased morale of victims. Pancasila values should be implemented by all Indonesian people, especially students, especially in the second precept which reads "Kemanusiaan yang adil dan beradab" which relates to cases of bullying, and socialization of cases of bullying is one of the efforts to prevent cases of bullying.

Abstract

Konvergensi media dan digitalisasi teknologi memfasilitasi arus informasi yang tidak terbatas dalam kehidupan sosial individu. Akibatnya, literasi media menjadi instrumen penting untuk bertahan dari tsunami informasi. Namun, pemerintah terus menghadapi hambatan dalam mempromosikan literasi media. Organisasi masyarakat sipil (OMS) dapat membantu pemerintah dalam mempromosikan literasi media dalam situasi ini. Studi ini bertujuan untuk mengeksplorasi strategi kampanye media sosial CSO Indonesia dan pentingnya tingkat keterlibatan media sosialnya. Untuk menentukan tingkat keterlibatan media sosial, metodologi campuran yang terdiri dari wawancara mendalam dan analisis konten selama setahun digunakan. Temuan mengungkapkan bahwa strategi storytelling dilakukan dalam tiga tahap: perencanaan, produksi, dan evaluasi. Konten media sosial terinspirasi dan dihasilkan berdasarkan laporan publik dan temuan independen selama tahap perencanaan. Konten tersebut kemudian diproses menggunakan paradigma sandwich selama fase produksi. Tujuan inti Mafindo dalam menyebarkan informasi ancaman disinformasi telah terpenuhi, meskipun engagement rate akun Mafindo (@turnbackhoaxid) belum mencapai tingkat optimal. Dengan demikian, masih ada ruang untuk perbaikan dengan mengoptimalkan mekanisme umpan balik audiens untuk membangun hubungan yang lebih kuat antara CSO dan audiens, yang dapat mengarah pada peningkatan dukungan dan dampak yang lebih besar untuk penyebabnya.

Abstract

Islamic banks as a company still have a goal of profit, where profit is often used as a measure of the company's performance. One of the profit ratios is the return on assets (ROA) ratio. Then the ROA in the previous study was influenced by many factors, while in this study it was seen based on the net performance financing (NPF) ratio, financing to deposit ratio (FDR), and net return (NI). The purpose of the study was to determine the effect of the NPF ratio, FDR ratio, and NI ratio on the ROA ratio. The research population was Islamic banks listed on the Indonesia Stock Exchange (IDX), namely 4 companies with data from the first-fourth quarter of 2021 to the second quarter of 2024. Panel data regression data analysis techniques. The results of the study showed that simultaneously net performance financing (NPF), financing to deposit ratio (FDR), and net return (NI) were significant on the return on assets (ROA) ratio, but partially net performance financing (NPF) did not affect the return on assets (ROA) ratio while financing to deposit ratio (FDR) and net return (NI) were significant on the return on assets (ROA) ratio.

Abstract

The aim of this research is to examine the profession of housewives who have an important role in a family, especially in managing finances for daily needs. The high level of spending in Indonesia causes people to have a wasteful lifestyle, but the adoption of a saving attitude can be influenced by other factors, for example television as a communication medium which can provide positive information content through television shows.  This research uses quantitative methods by distributing questionnaires to collect data and applying moderated regression analysis. Questionnaires were distributed to 100 housewife respondents in Cisaranten Kidul Village with the criteria of watching the FTV program "Pintu Berkah". The results showed that the influence of FTV broadcasts and religiosity had a positive effect on saving attitudes, as evidenced by the values of t = 3.278, p (0.001) α (5%) and t = 3.025, p (0.003) α (5%). Based on the results of these calculations, a housewife proves that with social cognitive theory, a person will learn through experience gained from the media or the environment. Housewife respondents who watch the FTV "Pintu Berkah" tend to be influenced by the program, which has gone through several stages of knowledge processing to then implement a frugal lifestyle in accordance with the religious values adhered to by each individual.
