Abstract

Gamification is one of the strategies widely applied by junior high school teachers in English language learning within their classrooms. However, the implementation of gamification thus far only focused on incorporating all gamification elements without considering which specific elements have the greatest impact on improving students' English proficiency. To fill this gap, this research is conducted to discover the gamification elements that can optimally increase English proficiency. Using survey method, this research involves 250 respondents from junior high school students in Kota Malang who have an experience in gamification strategies. The results show that gamification elements cannot increase students"™ English proficiency when implemented individually; while all involved gamification elements simultaneously affect the English proficiency. Therefore, to improve English proficiency, teachers should integrate all gamification elements within their instructional strategies. Because of its limitation, future research that involves respondents from different areas and school types needs to be conducted to provide a broader understanding of how these elements perform in various contexts.

Abstract

Seaweeds is a fishery commodity that has economic value and generates quite a large amount of foreign exchange. However, in its development, production fluctuated and not all marine locations could maintain seaweed throughout the year. Relatively low production costs and a market that is available at any time. The purpose of this study was to analyze the productivity and development strategies for Euchema cotonii grass cultivation in Banten Bay. Changes in spatial planning, land conversion, industrial activities in the western and eastern parts, waste disposal through the river in this section and the excavation of sand mines have made the bay very vulnerable to the environment. The location of this activity is the coast and waters around the island of  Banten Bay. The method of data collection is the measurement of water quality parameters in the field, surveys, interviews, discussions and limited participation in seaweed cultivation locations. The data analysis method is descriptive and uses the SWOT tool (Strength, Weakness, Opportunities and Threats) and uses SPSS version 25, excel and to assess sustainability using raphfish. Research results show. Water quality conditions are in accordance with the growth of seaweed. Production starting in 1987 fluctuated and conditions were stagnant in the last 3 years. The recommended strategy for increasing production is increasing grass productivity through expanding areas that have mapped potential and land suitability with applied technology, competent human resources, using superior seeds and reducing environmental pollution by industry and sand mining. KEYWORDS: Seaweed; Banten Bay; Environmental pollution; Serang.

Abstract

Nanopartikel Mn-Ferrite berbasis bahan alam pasir besi telah berhasil disintesis dengan metode kopresipitasi. Penelitian ini bertujuan untuk memperoleh nanopartikel Mn-Ferrite dari pasir besi dan menganalisis struktur kristal serta sifat kemagnetannya. Sampel disintesis dengan memvariasikan konsentrasi NaOH yaitu 3 M, 6 M, dan 9 M. Karakterisasi sampel dilakukan dengan X-ray diffractometer (XRD), tunneling electron microscopy (TEM), dan vibration sample magnetometer (VSM). Pola XRD menunjukkan bahwa nanopartikel Mn-ferrite telah berhasil disintesis yang ditandai dengan munculnya puncak difraksi khas spinel ferit. Pola XRD juga mendeteksi beberapa puncak difraksi lain yang diidentifikasi sebagai α-Fe2O3 (hematite). Parameter kisi ditemukan meningkat dari 8,32 hingga 8,38 Å seiring dengan meningkatnya konsentrasi NaOH. Ukuran kristalit diestimasi dengan persamaan Scherrer yang ditemukan antara 20 hingga 26 nm. Hasil TEM menunjukkan sampel mengalami aglomerasi akibat interaksi magnetik serta tingginya tegangan permukaan antar-butir nanopartikel. Kurva histeresis magnetik menunjukan bahwa sampel bersifat soft-magnetic. Magnetisasi saturasi terukur antara 11,2 emu/gram hingga 12,5 emu/gram, sedangkan koersivitas antara 98 Oe hingga 106 Oe. Hal ini dipengaruhi oleh keberadaan fase impuritas yang bersifat anti-ferromagnetik dengan persentase berbeda-beda untuk masing-masing sampel.

Abstract

Simbang Wetan Village faces a dual challenge: the accumulation of unmanaged flannel waste from the local convection industry and the need to enhance household-level food security. This community service activity aimed to transfer appropriate technology in the form of an innovative aquaponics wick system that utilizes flannel waste as a key functional component. The method employed a participatory learning approach, combining presentations, hands-on practice, and discussions. This activity was conducted on September 8, 2025, at the Simbang Wetan Village Hall, involving 24 residents. The program's success was measured quantitatively using pre-test and post-test instruments. Data analysis revealed a highly significant improvement in understanding and skills. Specific knowledge regarding the function of flannel fabric as an aquaponics wick surged dramatically from 8.3% in the pre-test to 100% in the post-test. Similarly, practical understanding of assembling the system from recycled materials increased from 4.1% to 87.5%. These results indicate that the workshop was highly effective in transferring knowledge and shifting the community's paradigm towards waste management. The broader adoption of this technology at the household level, along with continuous mentoring, is recommended to ensure program sustainability.

Abstract

SNA (Social Network Analysis) is a modeling method for users which is symbolized by points (nodes) and interactions between users are represented by lines (edges). This method is needed to see patterns of social interaction in the network starting with finding out who the key actors are. The novelty of this study lies in the expansion of the analysis of other suspects, not only key actors identified during this time. This method performs a narrowed network mapping by examining only nodes connected to key actors. Secondary key actors no longer use centrality but use weight indicators at the edges. A case study using the hashtag "Manchester United" on the social media platform Twitter was conducted in the study. The results of the Social Network Analysis (SNA) revealed that @david_ornstein accounts are key actors with centrality of 2298 degrees. Another approach found @hadrien_grenier, @footballforall, @theutdjournal accounts had a particularly high intensity of interaction with key actors. The intensity of communication between secondary actors and key actors is close to or above the weighted value of 50. The results of this analysis can be used to suspect other potential suspects who have strong ties to key actors by looking.

Abstract

The COVID-19 pandemic has changed how teachers teach and students learn in the classroom. One of the challenges in the online teaching is that teachers are required to prepare the instructional materials for their students. This study aims at investigating the EFL teachers’ reasons for choosing the instructional materials in the time of the COVID-19 pandemic. By employing a set of questionnaires, this study collected the data from 219 English teachers from various levels of education online via the google form link. The data collection was done for one month starting from 5 May to 5 June 2020. The data were analyzed through a content analysis by identifying, grouping, and categorizing similar and different responses. The results of analysis showed that the EFL teachers have five categories of reasons in selecting the instructional materials in the time of pandemic: the instructional materials should be easy, relevant, simple, attractive, and absent from crime, pornography, and viruses. These results suggest that the EFL teachers make use of these reasons in selecting and developing the instructional materials for their students during and after the pandemic. For future textbook developers, these considerations can be used a reference to develop textbooks which accommodate students’ voices and teachers’ voices during the online teaching and learning activities.

Abstract

Surface plasmon resonance (SPR) phenomenon was observed using the Kretschmann configuration with a four-layer structure: prism/Au Thin Film/ Fe3O4/Ag/air, with Fe3O4/Ag nanocomposite mass variation of 0.025; 0.05; 0.075; and 0.1 gram. Fe3O4 which was then added with 100 mM Ag to become Fe3O4/Ag 100 mM nanocomposite was synthesized using green synthesis method, and then characterized by XRD and UV-Vis. XRD results showed the addition of Ag to Fe3O4 does not change the crystal structure of Fe3O4 directly, but causes an increase in crystallite size. UV-Vis results showed the absorbance spectrum shifted to longer wavelengths. Deposition of Au thin layer on the prism side using vacuum evaporator. Fe3O4/Ag was deposited on the Au thin film using spray method. For the initial configuration of  prism/Au Thin Film/air, the SPR angle (θSPR) of 45.67º was obtain with a minimum reflectance (Rmin) of 0.4208. After the addition of Fe3O4/Ag with each mass, the SPR angle (θSPR) shifted to 45.98º; 46.38º; 46.75º; and 46.77º with a minimum reflectance (Rmin) of 0.5645; 0.6977; 0.7239; and 0.7663. The resulting angular shifts were 0.31º; 0.71º; 1.08º; and 1.11º. The results show that the addition of Fe3O4/Ag to the Au thin layer causes a shift in the SPR angle towards a larger incident angle, as well as increasing the minimum reflectance value. The greater the mass of nanocomposite added, the greater the SPR angle shift that occurs.     Keywords: Fe3O4/Ag nanocomposite, green synthesis, surface plasmon resonance (SPR), UV-Vis, XRD.
