Abstract

Malang is known for its diverse culinary attractions, particularly along Jalan Soekarno-Hatta, a popular culinary area. The linguistic landscape (LL) displayed in public spaces reflects the sociolinguistic characteristics of a region and can be observed through culinary store names. This study aims to identify the monolingual and bilingual patterns used in culinary store naming on Jalan Soekarno-Hatta and to analyze their informational and symbolic functions. This research employed a descriptive qualitative method. Data were collected from permanent signage along Jalan Soekarno-Hatta. Of the 181 stores identified, 80 were culinary businesses. The findings reveal 70 monolingual store names categorized into six patterns: P+BN, BN, TCS+P, TCS+P+BN, TCS+BN, and P. In addition, 10 bilingual store names were classified into three patterns: TCS+BN, P+BN, and TCS+P. The study shows that the informational function of the linguistic landscape is to communicate products and store locations, while the symbolic function reflects business ownership and the regional identity of the cuisine offered. These findings demonstrate how culinary store names contribute to representing cultural and linguistic identities in urban public spaces.

Abstract

Population growth, land-use conversion, and the reduction of vegetation cover have led to increasingly frequent floods and droughts in Semarang Regency. These conditions exacerbate surface runoff and reduce the soil’s capacity to store water, resulting in inundation during the rainy season and drought during the dry season. The objective of this study is to determine the location for installing Horizontal Recharge Pipes (HRP), which play an important role, particularly in flood-prone areas, by enhancing groundwater infiltration as a water reserve. The method applied in this research involves calculating the magnitude of runoff discharge in areas with potential flood inundation, which is then simulated with the application of HRP installation to determine the number of HRPs required to reduce flooding. Drought-prone areas were analyzed using satellite imagery to identify suitable HRP locations. In the Klegung watershed, 10 HRP units are required; in the Curug watershed, 460 units; and in the Lodong watershed, 835 units, all using a 12-inch diameter. Drought analysis using Landsat imagery identified dry areas in East Ungaran, Susukan, Suruh, Bancak, and Pringapus subdistricts. The installation points for HRPs can be prioritized based on areas experiencing inundation or drought. The implementation of HRPs is expected to infiltrate surface runoff effectively, thereby reducing flood risk while simultaneously increasing groundwater availability in Semarang Regency.

Abstract

The research was motivated by the increasing sexual behavior among adolescents due to low knowledge, environmental influences, and a lack of sex education. Therefore, MODISA was developed as a means of preventing promiscuous sexual behavior. The research aims to describe adolescents' understanding of sex education, map existing prevention efforts, and develop relevant, interesting, and appropriate modules. The method used in Research and Development with the ADDIE model includes the stages of analysis, design, development, implementation, and evaluation, which is limited to the development stage in the form of testing the feasibility of the module by experts and prospective users. Interview data analysis used the Miles and Huberman interactive model assisted by MAXQDA 2026 software, while the product acceptability analysis used the inter-rater agreement model. The results of the MODISA research respond to the needs of students and guidance counselors for comprehensive, easy-to-understand sex education materials equipped with illustrations. The validity test results obtained were 1.00 from material experts, media experts, and prospective users, thus indicating the validity results are in the very high category, meaning MODISA is very appropriate, very useful, very interesting, and very feasible to use. In conclusion, MODISA (Sex Education Module for Teenagers) has the potential to improve adolescents' knowledge, attitudes, and behavior towards the risks of sexual behavior, so that it can be a structured teaching material for high school guidance and counseling teachers in providing sex education.

Abstract

The existence of a web-based corpus of German texts created by students is crucial for both lecturers and students, as this corpus can be utilized as initial data for all research on German text writing skills. With a web-based platform, users can access the corpus in the form of a search engine, vocabulary list, word relevance, and frequency. Through the corpus database, lecturers and students can conduct research and observe patterns in students' ability to write German texts. The data collected in this study consists of student-written texts uploaded and stored in the system's database. This collection of texts is referred to as a journal. The journal data is used for the corpus system, which will be analyzed. In recent years, language teachers, particularly foreign language instructors, have had to incorporate corpora into their teaching. Through this corpus database, lecturers and students can conduct research and observe patterns in students' ability to write German texts.

Abstract

This study examines the influence of leadership style and incentive systems on employee performance from a management perspective. A quantitative survey approach was employed, with data collected through structured questionnaires distributed to employees. The data were analyzed using multiple linear regression to assess the partial and simultaneous effects of leadership style and incentive systems on employee performance. Instrument validity, reliability, and classical assumption tests were conducted to ensure the robustness of the model. The results reveal that leadership style has a positive and significant effect on employee performance, indicating that effective leadership practices such as providing clear direction, fairness, and motivation enhance employee outcomes. Incentive systems also demonstrate a positive and significant influence on performance, emphasizing the role of fair, transparent, and performance-based rewards in motivating employees. Moreover, leadership style and incentive systems jointly explain a substantial proportion of the variance in employee performance, suggesting their complementary role in performance management. These findings imply that organizations should adopt an integrated strategy by strengthening leadership effectiveness and aligning incentive systems with performance goals to enhance productivity and organizational sustainability. This study contributes to the human resource management literature by providing empirical evidence on the combined impact of leadership and incentives on employee performance.

Abstract

Natural disasters are traumatic events that can have significant psychological effects on children, who are emotionally vulnerable and rely on various coping strategies to manage trauma. This study examines the characteristics of trauma coping strategies used by children following a disaster and explores gender differences in the selection of these strategies. Five coping domains are analyzed: problem-focused coping, positive cognitive restructuring, support-seeking strategies, distraction strategies, and avoidance strategies. A quantitative survey approach with accidental sampling was employed. The participants were 889 children aged 10-12 years from 21 elementary schools in the Ponorogo area who were affected by a disaster. Data were analyzed using descriptive statistics through SPSS software. The findings reveal that positive cognitive restructuring is the most frequently used coping strategy among children after disasters. Gender differences were also identified, with girls use positive cognitive restructuring more often, while boys are more likely to employ distraction strategies to cope with psychological stress. These results highlight the importance of considering gender based coping patterns in post disaster psychological interventions. The study provides valuable insights for school and government agencies in developing effective coping strategy programs, particularly by strengthening positive cognitive restructuring skills to support children’s psychological recovery after disaster.

Abstract

The ability to write descriptive essays is an essential competence for students of English as a Foreign Language (EFL). However, many students still face difficulties in organizing ideas and producing systematic writing. This study aims to measure the effectiveness of the PDREF framework (Planning, Drafting, Revising, Editing, and Final Draft) in teaching descriptive essay writing. PDREF was applied as a process-oriented instructional framework in teaching writing. This study employed a quantitative approach using a one-group pre-test and post-test design. The participants of this study were 10 students from the English Education Department at Universitas Islam Balitar. The data were analyzed using a paired sample t-test through SPSS. The results of the analysis showed a significant improvement in students’ writing ability, with the mean score increasing from 65.40 in the pre-test to 82.70 in the post-test. The paired sample t-test result indicated a significance value of 0.000 (Sig. 2-tailed < 0.05), which means that there was a significant difference before and after the implementation of the PDREF framework. Therefore, the PDREF framework is found to be effective in improving EFL students’ descriptive essay writing skills, particularly in terms of idea organization and descriptive quality.

Abstract

Nypa fruticans Wurmb. is a rich source of bioactive phytochemicals, including flavonoids, phenolic, and tannins. This study aimed to evaluate the antioxidant activity of Nypa fruticans Wurmb. leaf extract and investigate its potential as a bioreducing agent for the green synthesis of AgNPs. The leaf extract was prepared using the maceration method, while antioxidant activity was determined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. AgNPs were synthesized via a precipitation-based green synthesis approach and subsequently characterized by UV–Visible spectroscopy to monitor the formation of the surface plasmon resonance band. The extraction process yielded a crude extract with a recovery of 17%. The DPPH assay demonstrated a strong antioxidant activity, with an IC₅₀ value of 7 μg/mL. Optimization of the biosynthesis process revealed that an extract volume of 7 mL, a reaction temperature of 50 °C, and a reaction time of 90 min were the optimal conditions for the reduction of Ag⁺ ions, resulting in optically stable AgNPs. The successful formation of AgNPs was confirmed by an increase in SPR intensity accompanied by a red shift in the absorption wavelength, indicating nanoparticle growth. These findings suggest that Nypa fruticans Wurmb. is not only an effective source of natural antioxidants but also a promising eco-friendly bioreducing agent for the green synthesis of silver nanoparticles.

Abstract

A jet bubble column is a reactor used in various process fields that functions to produce a strong liquid flow and expand the contact area between gases, liquids, and solids. However, research studies on the application of jet bubble columns for industrial wastewater treatment processes are still relatively limited. This study aims to modify the jet bubble column so that it can reduce the levels of heavy metals in industrial liquid waste. The tool is modified by adding granular adsorbents to the inside of the column which are held on a perforated plate holder. The tools and materials used include 5-inch PVC pipes, ½-inch PVC pipes, pipe fittings, pipe caps, hollow iron, DC pumps, valves, and brass nozzles. The jet bubble column tool has a fluid volume capacity of 5 L, a jet pump with a maximum pressure of 90 bar, a fluid flow rate of 7 L/minute, and a process time of 30 minutes. The test results show that the jet bubble column is able to reduce the levels of hexavalent heavy metals in industrial liquid waste by up to 83.67% with a contact time of 30 minutes. This shows better performance compared to the use of commonly used mechanical stirring.
