Abstract:This study aims to Test Wastewater Quality Using the Mpn (Most Probable Number) Method to Detect Total COLIFORM Bacteria. This study uses laboratory analysis, which aims to provide an overview of the microbiological quality…
ity of wastewater based on the presence and number of Coliform bacteria. The working principle of the Most Probable Number (MPN) method in detecting total Coliform bacteria in wastewater is carried out semi-quantitatively by detecting microbial growth through lactose fermentation which produces gas or turbidity in selective liquid media. The implementation procedure includes a presumptive test stage using Lactose Broth (LB) media, a confirmatory test with Brilliant Green Lactose Bile Broth (BGLB) media, and determining the final value by matching the combination of positive tubes with the standard MPN table. From the results of laboratory testing on three domestic wastewater samples (1224 AL, 1225 AL, and 1226 AL), it was found that all samples showed negative results with a combination of 0-0-0 tubes in the presumptive test. This indicates that the tested sample does not contain Total Coliform bacteria or has a value of less than 1000 MPN/100 mL, so that its microbiological quality is declared very good and has met the quality standard threshold set by the government through the Minister of Environment Regulation No. 5 of 2014 and PP RI No. 22 of 2021
Abstract:The aim of the research describes the representation of Islam in America in the TED Talks Youtube Channel video entitled What It's Like to be a Muslim in America. The research are analyzed including obtaining forms of representation…
presentation of Islam in America, describe the representation of Islam in America and describe the implementation of the Cross Culture Understanding course on the condition of Muslims and Islam in America.
The methodology of research utilized to analyze this video is a semiotic structural methodology based on Roland-Barthes theory, that was construct a structured sign system in the format of denotative and connotative signs. After the writer analyzed in the TED Talks Youtube Channel video entitled What It's Like to be a Muslim in America with using denotative and connotative analysis. Finally, the author can describe the inference that Islam representation in America consist of 3 constructions. To describe the representation of Islam in America after the tragedy in America on September 11, 2001 as the shape of Islamophobia, and the results of this research can be implemented with the theories of the Cross Culture Understanding course
Abstract:Penelitian ini bertujuan untuk menghasilkan media permainan kantong karir yang layak sebagai sarana pemberian layanan informasi untuk membantu perencanaan karir siswa kelas XI MAN 1 Kota Serang. Jenis penelitian ini adalah…
ah Research and Development (R&D) dengan menggunakan model pengembangan ADDIE yang terdiri dari lima tahapan yaitu Analysis, Design, Development, Implementation, dan Evaluation. Hasil analisis kebutuhan menunjukkan bahwa 10% siswa memiliki tingkat perencanaan karir rendah, 75% sedang, dan 15% tinggi. Hal ini mengindikasikan masih diperlukannya layanan untuk membantu meningkatkan perencanaan karir siswa. Hasil validasi ahli materi, media, dan praktisi menunjukkan bahwa media kantong karir sangat layak digunakan dengan persentase kelayakan masing-masing media sebesar 100%, materi 80%, dan praktisi 100%. Kemudian rata-rata keseluruhan sebesar 93%. Pada uji coba terbatas, terjadi peningkatan skor perencanaan karir siswa antara sebelum (pretest) dan sesudah (posttest) menggunakan media kantong karir. Hasil uji Wilcoxon menunjukkan perbedaan yang signifikan antara skor pretest dan posttest (Z=-2,805; p=0,005), yang berarti penggunaan media kantong karir efektif dalam meningkatkan perencanaan karir siswa. Peningkatan perencanaan karir terlihat dari meningkatnya pemahaman siswa mengenai potensi diri, arah pilihan karir yang sesuai, serta kemampuan dalam mengambil keputusan karir. Dengan demikian, media permainan kantong karir yang dikembangkan terbukti layak dan efektif digunakan sebagai sarana pemberian layanan informasi untuk membantu meningkatkan perencanaan karir siswa kelas XI MAN 1 Kota Serang. Media ini dapat menjadi alternatif bagi guru bimbingan dan konseling dalam memberikan layanan bimbingan karir yang menarik dan efektif.
