Abstract

Teaching speaking is not easy. The teacher has to use an appropriate technique in teaching speaking. The research problem came from the Eighth Grade students of SMPN 1 Arjawinangun Cirebon. The students were passive in conversation when someone talked in English because the teacher taught using traditional method which made them bored and could not give feedback in English conversation. On the students’ side, they get difficulties in learning speaking because they felt bored and passive during teaching and learning process. This research aims to explain how significant the students’ achievement taught by using role play and information gap technique conducted with high and low self-confident of students in e-teaching speaking context. The research design was a quasi-experimental design with a 2x2 factorial design involving the eighth-grade students SMPN 1 Arjawinangun, Cirebon as the research participants. There were two experimental groups involved. The students’ different self-confidence was taken as a factor that might influence the techniques. In collecting the data, the writer used speaking test to get students’ scores and questionnaires made by Google Form and on-line system. The data was analyzed using ANOVA to answer the main hypotheses. Based on the analysis of the significance score was 0.178 which was higher than 0.05. It can be concluded that there was no significant difference on the students’ achievement taught by role play and information-gap for students with high and low self-confidence. This research is expected to give a contribution to the research such as giving appropriate technique to teach speaking in e-learning.

Abstract

The by.U product is the first digital prepaid cellular service in Indonesia that provides an end-to-end digital experience for all telecommunications needs. by.U was developed specifically for the Gen Z segment in Indonesia, which at that time was projected to number around 44 million people.

This research aims to determine the description of social media marketing activities, brand image, brand awareness and Brand Equity at by.U based on respondents' opinions. This study uses quantitative data collected based on filling out questionnaires carried out by 272 respondents who have used or are currently using by.U products, with the criteria that people who follow or have followed by.U social media have the desire to buy byU products in the future come. Sampling was carried out by purposive sampling. Data analysis was carried out using SEM techniques via the SmartPLS application. This study shows that social media marketing activities have a significant influence on brand awareness and brand image, which in turn contribute positively to brand equity and purchase intention.

Abstract

This study investigates consumer preferences and demand elasticity in the soft drink and coffee industry, focusing on the context of monopolistic competition. Through a qualitative approach that combines literature review analysis with empirical methods, we gathered data from consumer surveys and simulated shopping experiments to understand market dynamics and consumer behavior. The analysis reveals that the level of product differentiation influences consumer loyalty and demand elasticity. Brands with high differentiation tend to have higher consumer loyalty and lower demand elasticity. The practical implications of these findings emphasize the importance for companies to strengthen product differentiation, understand consumer preferences, and adjust marketing strategies according to demand elasticity to maintain market share and enhance profitability. These findings provide valuable insights for strategic decision-making in the soft drink and coffee industry. Penelitian ini menyelidiki preferensi konsumen dan elastisitas permintaan dalam industri minuman ringan dan kopi, dengan fokus pada konteks persaingan monopolistik. Melalui pendekatan kualitatif yang menggabungkan analisis kajian pustaka dengan pendekatan empiris, kami mengumpulkan data dari survei konsumen dan eksperimen simulasi belanja untuk memahami dinamika pasar dan perilaku konsumen. Hasil analisis menunjukkan bahwa tingkat diferensiasi produk memengaruhi tingkat kesetiaan konsumen dan elastisitas permintaan. Merek-merek dengan diferensiasi yang tinggi cenderung memiliki tingkat kesetiaan konsumen yang lebih tinggi dan elastisitas permintaan yang lebih rendah. Implikasi praktis dari temuan ini adalah pentingnya perusahaan memperkuat diferensiasi produk, memahami preferensi konsumen, dan menyesuaikan strategi pemasaran dengan tingkat elastisitas permintaan untuk mempertahankan pangsa pasar dan meningkatkan profitabilitas. Temuan ini memberikan wawasan yang berharga bagi pengambilan keputusan strategis dalam industri minuman ringan dan kopi.

Abstract

Indonesia memiliki keanekaragaman hayati laut tertinggi di dunia dengan sekitar 569 spesies dan 83 genus karang batu (stony coral ) yang mencakup 69% spesies dan 76% genus dari total karang batu global. Namun terumbu karang sangat rentan terhadap perubahan iklim. Faktor lingkungan dapat merusak fotosistem II, menyebabkan hilangnya alga simbiotiknya dan tampak memutih. Penerapan model Support Vector Machine (SVM) dan Bag of Features (BoF) dilakukan sebagai solusi AI untuk mengklasifikasikan kondisi terumbu karang. Namun, pendekatan ini mengandalkan ekstraksi fitur manual dan memerlukan alur kerja yang lebih kompleks dibandingkan metode pembelajaran mendalam end-to-end seperti CoralNet, InceptionV3, dan MobileNetV 2. Penelitian ini bertujuan untuk analisis kinerja analisis dari model ketiga tersebut dalam mengklasifikasikan kondisi terumbu dalam kelas sehat, diputihkan, dan mati . MobileNetV2 memberikan hasil terbaik dengan akurasi pelatihan 97%, validasi 88%, dan pengujian 89% untuk klasifikasi terumbu karang.
