Abstract

This study aimed to determine the best initial seedling weight in Kappaphycus alvarezii seaweed cultivation using the floating raft . This research was conducted for 52 days, starting from May to June 2021, in Berakit Village, Riau Islands. The method used was Completely Randomized Design (CRD) with 3 treatments and 3 replications, Treatment A (Seed weight 50 g), Treatment B (Seed weight 100 g) and Treatment C (Seed weight 150 g). The results of the study after the statistical test of variance ANOVA, the effect of different seed weights on the growth rate of Kappaphycus alvarezii seaweed Using the floating raft method showed significantly different results on the growth rate of seaweed (P<0.05).

Abstract

This research is about the growth rate of green and brown Kappaphycus alvarezii seaweed in different cultivation methods. This study aims to compare the growth of Kappaphycus alvarezii green and brown varieties and determine the appropriate cultivation method for waters in the Riau Islands. This research was conducted from 27 May 2021 to 11 July 2021 for 45 days in Berakit Village, Teluk Sebong District, Bintan Regency, Riau Islands Province. In this study, there were two variations, namely the green variety and the brown variety with a Randomized Block Design (RAK) with each variation having 3 treatments and 3 replications. The parameters measured were absolute weight growth, specific growth rate, survival and water quality. Data analysis used a two-way ANOVA test of variance and continued with the Tukey test. The results showed that the highest seaweed growth was found in green varieties with the best cultivation method being floating rafts.

Abstract

Seorang mahasiswa yang memiliki segudang aktivitas dan mengalami kendala dalam mengatur waktu dalam kegiatan perkuliahan, organisasi dan permasalahan hidup dapat mengalami stres. Sehingga mahasiswa membutuhkan cara untuk menghilangkan stres yang dialaminya, salah satunya dengan melihat tayangan humor. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan tingkat stres mahasiswa Fakultas Psikologi UIN Raden Fatah Palembang antara sebelum dan sesudah diberikan tayangan humor. Jenis penelitian ini adalah eksperimen kuantitatif. Pada penelitian ini desain eksperimen yang digunakan adalah single group pre and post test design yaitu desain eksperimen yang hanya menggunakan satu kelompok subjek dan dilakukan pengukuran sebelum dan sesudah perlakuan terhadap subjek (Latipun, 2011). Hasil penelitian ini adalah humor tidak berpengaruh terhadap stres mahasiswa yang dibuktikan dengan uji t berpasangan menggunakan software SPSS 16.0 dengan nilai signifikan (0,228 > 0,05). Hal ini menunjukkan bahwa humor yang ditampilkan tidak berpengaruh terhadap pengalaman stres orang yang sedang diuji.

Abstract

This study was prompted by the inadequate grasp of students' comprehension in various dimensions of science, encompassing content, context, processes, and scientific attitudes, alongside the limited availability of laboratory resources within the school setting. The primary objective was to discern variations in the attainment of scientific literacy scores among sixth-grade students studying Natural Sciences at UPTD SDN Socah 3. The research enlisted 23 sixth-grade students from UPTD SDN Socah 3 as participants. Employing a pre-experimental approach, the study utilized the One Group Pretest Posttest Design. Upon analyzing the data using paired sample t-test at a significance level of 0.05, the null hypothesis (Ho) was rejected, and the alternative hypothesis (Ha) was accepted. The noteworthy disparity between pre-test and post-test outcomes was substantiated by the computed t-value (13.445), surpassing the critical t-table value (2.074). Consequently, it can be deduced that employing PhET Simulation media yielded a considerable impact in augmenting students' scientific literacy skills pertaining to the comprehension of Natural Science material among sixth-grade students at SDN Socah 3.

Abstract

Opportunities for crime in the digital business world include various forms of threats, such as system hacking, theft of personal data, financial fraud, and other criminal acts that can harm companies and damage consumer trust. Digital business is a business activity that in its implementation utilizes technology as a medium, either when creating or in a series of marketing activities. In an effort to deal with opportunities for crime in the world of e-business, companies must prioritize information security, strict policy implementation, education and training for employees, as well as partnerships with security and government agencies. This research uses a qualitative literature study method by obtaining secondary data through published journal articles with the question "Are there many opportunities for crime in the utilization or use of e-business?". Based on this, it is clear that there are still many opportunities for crime in the digital business world and continue to occur, where the crimes that often occur are fraud, hacking, as well as cybercrime and cyberfraud.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran joyfull learning terhadap kemampuan numerasi materi pecahan siswa. Pada penelitian ini digunakan metode kuantitatif dengan model Quasi Experiment dalam bentuk desain penelitian yang digunakan Nonequivalent Control Group Design. Kemampuan numerasi sebagai variabel terikat sementara itu model pembelajaran joyfull learning sebagai variabel bebas. Subjek penelitian adalah siswa kelas 3 SDN Banyuajuh 3, dengan teknik nonprobality sampling. Teknik pengumpulan data yang digunakan berupa observasi dan wawancara. Berdasarkan hasil analisis melalui independent t test dua variabel diketahui bahwa  > atau 3.028 > 1.739, maka dapat dinyatakan H0 ditolak dan Ha diterima. Hasil tersebut berarti terdapat perbedaan kemampuan numerasi antara kelas eskperimen dan kelas kontrol, sehingga dapat disimpulkan bahwa terdapat pengaruh yang signifikan pembelajaran dengan model pembelajaran joyfull learning terhadap kemampuan numerasi materi pecahan siswa kelas III SDN Banyuajuh 3.
