AgandCuloadedonTiO2/graphite as a catalyst for �Escherichia coli- contaminated water disinfection
Full text linkTiO2 film was synthesized by means of the chemical bath deposition (CBD) method from TiCl4
as a precursor and surfactant cetyl trimethyl ammonium bromide (CTAB) as a linking and assem-
bling agent of the titanium hydroxide network on a graphite substrate. Ag and Cu were loaded
on the TiO2 film by means of electrodeposition at various applied currents. Photoelectrochemical
testing on the composite of Ag–TiO2/G and Cu–TiO2/G was used to define the composite for
Escherichia coli-contaminated water disinfection. Disinfection efficiency and the rate of disinfection
of E. coli-contaminated water with Ag–TiO2/G as a catalyst was higher than that observed for
Cu–TiO2/G in all disinfection methods including photocatalysis (PC), electrocatalysis (EC), and
photoelectrocatalysis (PEC). The highest rate constant was achieved by the PEC method using
Ag–TiO2/G, k was 6.49 × 10−2
CFU mL−1

Kata Kunci: problem solving, media pembelajaran, prestasi belajarPembelajaran di kelas cenderung membuat siswa kurang kreatif dan pasif dalam memecahkan masalah. Kesulitan memecahkan masalah dikarenakan metode pembelajaran yang digunakan masih membuat siswa kurang antusias dalam memperhatikan materi pembelajaran yang disampaikan guru. Selain itu guru tidak memberikan contoh penyelesaian masalah sebelum siswa melakukan pemecahan masalah. Hal ini menyebabkan prestasi belajar siswa rendah.Penelitian dengan penerapan Metode Problem solving ini dilakukan dalam upaya meningkatkan motivasi, pemahaman dan kemampuan memecahkan masalah pada pemrograman array dan teknik sorting. Metode problem solving melatih siswa dalam menghadapi masalah. Siswa dipacu untuk kreatif, aktif, dan tanggap dalam menghadapi berbagai masalah pada pemrograman. Sedangkan guru memotivasi, memberikan arahan dan menjadi fasilitator. Untuk membantu guru dalam menguatkan konsep dengan simulasi/tahap-tahap pemecahan masalah guru menggunakan bantuan media pembelajaran. Penelitian ini menggunakan rancangan Quasi ekperimental design tipe Nonequivalent Control Group Design . Sampel yang digunakan sebanyak dua kelas yaitu kelas X RPL-3 sebagai kelompok eksperimen (kelompok yang diberi perlakuan menggunakan metode problem solving berbantuan media pembelajaran dan kelas X RPL 2 sebagai kelompok kontrol digunakan metode pengajaran langsung. Teknik analisis data menggunakan uji hipotesis dengan teknik uji-t dua pihak yang digunakan untuk mengetahui perbedaan prestasi belajar siswa serta menggunakan analisa regresi sederhana untuk mengetahui pengaruh metode problem solving terhadap prestasi belajar pemrograman Visual Basic.Hasil analisis data menunjukkan bahwa: (1) prestasi belajar metode problem solving berbantuan media pembelajaran telah terjadi peningkatan prestasi belajar, hal ini dapat dilihat pada nilai kemampuan awal siswa dengan nilai rata-rata sebesar 56,56, setelah diadakan perlakuan nilai rata-ratanya menjadi sebesar 87,47, sedangkan prestasi belajar menggunakan metode pengajaran langsung hanya 80,98 dari kemampuan awal 53,56. (2) adanya perbedaan prestasi belajar pada kelas kontrol dan eksperimen. Hal ini dibuktikan dari nilai Sig < 0,05 pada uji-t dua pihak. Dari hasil analisis, dapat disimpulkan bahwa ada perbedaan yang signifikan rata-rata antara kelas eksperimen dibanding kelas kontrol.

Full text linkThis study aims to analyzing the factors that affect the readability of
labor to work abroad (case: The city of Semarang). The large number of workers
in the city of Semarang that has not accommodated by the jobs available in the
country especially in the city, which resulted in open unemployment increased
each year (BPS data for the period 2004-2008).The Labors can not be
accommodated in the country (especially the city of Semarang), to seek
employment outside the area of origin (domestic), if out of area of origin
(domestic) still can not accommodate, then the other alternative is to work
abroad. Where the number of workers who work outside the country of origin of
Semarang is not maximized, and the opportunity to work abroad is still so large
(Semarang city of 120 people in 2008), compared with the number of jobs and the
number of open unemployment in the city of Semarang. Because of this, allowing
workers to find jobs outside the region and even abroad. This research takes the
primary data through a questionnaire with a list of questions that have been
prepared. There are 100 job seekers who respondent using methods appropriate
Ak1 card makers (job seekers) in the Department of Manpower and
Transmigration.
To achieve these objectives, this study used logistic regression
techniques (Tobit Regression). Independent variables used include age, marital
status, occupation of respondents in the regions of origin, education, number of
dependents, the income is obtained, whereas the dependent variable is the
readability in migration. Data analysis using regression (Tobit model) shows the
variables that affect the readability of labor to work abroad is the variables of age
(prob.0,0001), job respondents (Prob.0,0003), occupation of respondents in the
regions of origin (Prob. 0,0077). Education (Prob. 0.0548*) And income (Prob.

Game Edukasi Belajar Alat-alat Transportasi Untuk Anak Berkebutuhan Khusus (ABK) Tunagrahita Di Sekolah Luar Biasa (SLB) Rahmawati Kholid Karanganyar
Full text linkMeans of transportation are something that is closely related to life and never escapes sight. Therefore, it is very important to learn it, especially for children who are starting to enter school. Apart from normal children, the category of children who need more attention is children with special needs (ABK) who are mentally retarded. Mentally retarded children are a group of children whose thinking patterns are not like normal children in general, this category of children tends to be slow and difficult to think. At the Rahmawati Kholid Special School (SLB), learning methods related to transportation equipment currently still use the old method, namely with the help of visual media such as pictures, LKS books and so on. This method does not attract the attention of mentally retarded students, students tend to get bored easily and get fed up with learning. This makes students do things outside of learning, such as disturbing friends, running around, thus creating a teaching and learning atmosphere that is not conducive. Based on the problems that occurred, the author has conducted interviews and discussions with teachers at the school, the result is that this SLB requires an educational game-based application as a companion medium for learning related to transportation. It is hoped that the design of this educational game can create more enjoyable teaching and learning activities as well as foster interest and motivate students to learn. The author used the Construct 2 application to design this game and was guided by the GDLC (Game Development Life Cycle) method in developing the game. The game that has been designed is tested in 2 stages, namely alpha testing using a black box to minimize errors and beta testing using the SUS method. The results of usability testing calculations using the (SUS) method obtained an average score of 84.58 so this application can be classified in the Excellent category and get grade B
Emotional Analysis of the Main Character in Leiden by Dwi Nur Rahmawati: Implications for Literature Education in the Merdeka Curriculum
Full text linkThis study examines the emotional dynamics of the main character in Dwi Nur Rahmawati\u27s Leiden and analyzes how these emotions can inform literature teaching within the Merdeka Curriculum. Employing a descriptive mixed-methods design, the research integrates qualitative literary psychology analysis with quantitative frequency mapping. Data were collected through systematic reading, identification of emotional expressions, structured recording, and coding of 76 emotional quotations from the novel. Analysis followed Miles, Huberman, and Saldaña\u27s interactive model to classify emotion types, examine narrative contexts, identify patterns, and interpret pedagogical relevance. The findings revealed three significant patterns. First, sadness emerged as the dominant emotion (18.4%), followed by love and fear (14.5% each) and guilt (11.8%), indicating the protagonist\u27s psychological vulnerability characteristic of adolescent development. Second, nonverbal behavior (39.5%) and author narration (35.5%) appeared more frequently than dialogue (25%), demonstrating a "show, don\u27t tell" characterization strategy requiring inferential reading. Third, complex emotions appeared in 10.5% of instances, exclusively through author narration, reflecting psychological nuance demanding higher-order interpretation. These emotional patterns are pedagogically relevant because they mirror adolescents\u27 socioemotional experiences and provide opportunities for developing empathy, emotional literacy, and analytical reading skills. The findings demonstrate that emotional analysis can serve as a foundation for designing character-oriented literature activities aligned with Phase F learning outcomes in the Merdeka Curriculum. The study contributes empirical support for integrating literary psychology into Indonesian literature classrooms through structured emotional mapping and offers practical guidance for teachers seeking to enhance students\u27 character formation and critical comprehension within curriculum frameworks emphasizing competency-based, analytical, and reflective learning
