Abstract

Processing river watersheds is very important because the risk of disasters caused by overflowing river water will be reduced if the watershed is well maintained. If DAS information is complete, DAS maintenance can run well. However, very little information is currently available. Therefore, we need a system that can be used to monitor DAS. The system will be a web-based Semarang City Watershed Monitoring Information System which can show the current condition of the watershed. This system has the ability to monitor watershed areas around Semarang, and if the watershed conditions are unstable, this system can repeat before any harm occurs to local residents. The results of watershed data collection can provide users with information regarding the location of dams and their descriptions, the river network in the watershed. Data collection is carried out by collecting information via the internet. Relevant data regarding watersheds which includes information on watershed conditions. The aim of this research is to build online-based monitoring media using content management systems such as WIX media so that it can expand monitoring of rivers that cannot be seen directly. Apart from that, it also aims to bring greater awareness to the current condition of River Watersheds (DAS). By designing appropriate monitoring media, we can more effectively introduce the actual situation of the watershed which has the potential to encourage increased awareness of environmental protection and management. The method used by this research is the Waterfall method in which there are several stages such as Requirements System, System and Software Design, Implementation and Until Testing, Integration System Testing, Operation and Maintenance. The results of this research indicate that the development of this website is to update existing information and make it easier for customers to access information about DAS anytime and anywhere.

Abstract

Writing ability is one of the skills that must be mastered by grade VIII students in Indonesian language learning. Students’ ability to master the vocabulary and spelling of the words they use to express their ideas is very important in writing poetry. Based on the results of observations at Darul Hikam Junior High School, it shows that there are still student obstacles in writing poetry in class so that students feel less effective in expressing their ideas and objects. In addition, teachers still use traditional Indonesian language learning methods with teacher-related approaches in daily teaching and learning activities. A teacher’s skill in choosing effective learning strategies and methods can improve students’ poetry writing skills. Learning methods and strategies that increase students’ poetry writing skills are the Think Plus Strategy with the Outdoor Study Method. This study aims to find and explain the impact of thinking and strategies using the outdoor study method on grade VIII students of Smp Darul Hikam Kuwarasan in the 2023/2024 academic year. The method applied in this research is experimental method with one group pretest and posttest design. The sample in this study was formed from 24 students. Normality and homogeneity testing using the SPSS application illustrates the significance value of Sig. 0.571 > 0.05 and 0.412 > 0.05 illustrating that the class is normally distributed and homogeneous. Data on learning outcomes were analyzed using paired sample t-test with 5% confidence level. Based on the results of the SPSS test, the Sig (two-tailed) significance value is 0.032 <0.05, so it can be said that the strategy of thinking plus with the outdoor study method has a significant effect on improving the poetry writing skills of students in grade VIII of Darul Hikam Kuwarasan Junior High School in the 2023/2024 academic year.

Abstract

Long-term meteorological data is very useful for identifying signs of climate change phenomena. The phenomenon refers to long-term changes in the physical conditions of the Earth's atmosphere, such as temperature and weather patterns. This has a huge impact, especially in Banyuwangi, which is one of the largest rice production areas in East Java. Predicting monthly rainfall trends is important to anticipate crop failures due to extreme weather and natural disasters such as floods and landslide. This research uses weather parameters on a global scale, such as temperature, rain, evaporation, surface humidity, and sea level pressure, while for local-scale information, it uses monthly rainfall data in the Banyuwangi area from 2011 to 2023.The extreme gradient boosting (XGBoost) method will be used to predict monthly rainfall in an ensemble learning model based on the boosting approach. In particular, this study emphasizes its ability to build predictive models on limited time series and the impact of data splitting on model performance. The best results were shown by the model with a data split ratio of 1:12, or covering 80% of the data as training data. The model accuracy achieved a MAE of 72.579 mm in training and 80.777 mm in testing. In addition, the RMSE was 95.940 mm in training and 95.775 mm in testing. The results of this study are expected to be a reference for building a more optimal long-term weather forecast model.

Abstract

In the current digital era, promotion through visual media is the key to introducing products or business premises to the public. By using video as a promotional medium, companies can expand their marketing reach and make information more interesting and easy for consumers to understand. The problem faced by Kopi Sembilan is the lack of a creative and attractive promotional strategy, as well as not highlighting their Unique Selling Proposition (USP) in every product they promote. In comparison, their competitors were already using video to promote their products, giving them a significant competitive advantage. By studying the creative and technical aspects behind making advertising videos using live shoot and motion graphic technology, this research produced an advertising video that was rated very good by respondents, with a total percentage of 88.2%. This video was broadcast on Kopi Sembilan's official Instagram and received a positive response from the public. However, this research still has several shortcomings, such as the need to add creative elements such as 3D animation, improve animation smoothing, and add voice dubbing to increase the visual and audio appeal of advertisements. It is hoped that this suggestion can be taken into consideration for further development so that the promotion of Kopi Sembilan becomes better and more effective.
