Abstract

This study is a qualitative descriptive research with the aim of describing students' mathematical problem solving with Field Dependent (FD) and Field Independent (FI) cognitive styles. The subjects of this study consisted of 2 grade VIII junior high school students with Field Dependent (FD) and Field Independent (FI) cognitive styles. The selection of both subjects also considers equal mathematical ability, equal gender, communicative, and willing. The data is analyzed based on the polya problem-solving stages, namely understanding the problem, planning the solution, implementing the solution plan, and rechecking. The results of the study showed that the mathematical problem solving of the two students in solving the problem was relatively the same. At the stage of understanding the problem, both students are able to write down what is known and what is asked in the question, but FD tends to write the same thing about what is in the problem while FI uses his own language. At the stage of planning the settlement of FD fans, FIs are equally able to make strategies or steps to solve the problem. At the stage of implementing the settlement plan, FD and FI are both able to carry out the strategy that has been prepared previously. FI is confident that the answer obtained is correct. However, it is different from FD where he is not sure or doubtful about the answer because in the process of solving the problem there are errors caused by lack of thoroughness. At the stage of re-checking, the FI confidently said that he had re-examined carefully and was confident in the answers obtained. In contrast to FD who said he had double-checked but was not sure whether the answer obtained was correct or not.

Abstract

The coffee shop industry in Indonesia has experienced significant growth, particularly in Surabaya, where Generation Z has shown a strong interest in coffee shop culture as a social gathering place. The increasing number of coffee shop options has created a need for objective recommendations to assist consumers in selecting the best coffee shop, as evaluations are often subjective. This study aims to determine the priority order of criteria considered by Generation Z in selecting a coffee shop using the Analytical Hierarchy Process (AHP) method and to identify the best coffee shop using the Simple Additive Weighting (SAW) method. This research employed a Multi-Criteria Decision Making (MCDM) approach by integrating the AHP and SAW methods. The data were collected through an online questionnaire distributed to 126 Generation Z respondents who had visited at least two of the four selected coffee shops, namely Toko Kopi Harlem, Kopi Toko Djawa, Coste Coffee, and Just Little Cave. These four coffee shops were selected based on their high popularity on social media, particularly TikTok, as well as their similar price ranges and store atmosphere. The evaluation was conducted using seven criteria: price, service, facilities, taste, location, store atmosphere, and Instagrammability. The results showed a Consistency Ratio (CR) value of 0.0082 (< 0.1), indicating that the pairwise comparison judgments were consistent. The priority order of the criteria preferred by Generation Z was taste (0.2904), store atmosphere (0.1652), facilities (0.1412), service (0.1149), Instagrammability (0.1110), price (0.0934), and location (0.0839). The SAW ranking results indicated that Coste Coffee achieved the highest preference value (0.9873), followed by Just Little Cave (0.9671), Toko Kopi Harlem (0.9484), and Kopi Toko Djawa (0.9424). Therefore, Coste Coffee is recommended as the best coffee shop for Generation Z in Surabaya based on the selected evaluation criteria. ABSTRAK Perkembangan industri coffee shop di Indonesia mengalami pertumbuhan yang pesat, khususnya di Surabaya yang menjadi salah satu kota dengan tingginya minat generasi Z terhadap budaya “nongkrong” di coffee shop. Banyaknya pilihan coffee shop menyebabkan konsumen membutuhkan rekomendasi dalam menentukan coffee shop terbaik secara objektif karena penilaian sering kali bersifat subjektif. Penelitian ini bertujuan untuk menentukan urutan kriteria yang diprioritaskan generasi Z dalam memilih coffee shop menggunakan metode Analytical Hierarchy Process (AHP) serta menentukan peringkat coffee shop terbaik menggunakan metode Simple Additive Weighting (SAW). Penelitian ini menggunakan pendekatan Multi-Criteria Decision Making (MCDM) dengan kombinasi metode AHP-SAW. Data diperoleh melalui kuesioner online terhadap 126 responden generasi Z yang pernah mengunjungi minimal dua dari empat coffee shop yang dijadikan alternatif, yaitu Toko Kopi Harlem, Kopi Toko Djawa, Coste Coffee, dan Just Little Cave. Keempat coffee shop tersebut dipilih karena memiliki popularitas tinggi di media sosial, khususnya TikTok, serta memiliki rentang harga dan store atmosphere yang relatif serupa. Penilaian dilakukan berdasarkan tujuh kriteria, yaitu harga, pelayanan, fasilitas, rasa, lokasi, store atmosphere, dan instagramable. Hasil penelitian menunjukkan nilai consistency ratio (CR) sebesar 0,0082 (<0,1) sehingga penilaian dinyatakan konsisten. Urutan kriteria yang diprioritaskan generasi Z adalah rasa (0,2904), store atmosphere (0,1652), fasilitas (0,1412), pelayanan (0,1149), instagramable (0,1110), harga (0,0934), dan lokasi (0,0839). Hasil pemeringkatan dengan metode SAW menunjukkan Coste Coffee memperoleh nilai preferensi tertinggi (0,9873), diikuti Just Little Cave (0,9671), Toko Kopi Harlem (0,9484), dan Kopi Toko Djawa (0,9424). Dengan demikian, Coste Coffee direkomendasikan sebagai coffee shop terbaik bagi generasi Z di Surabaya berdasarkan kriteria yang telah ditentukan.

Abstract

ABSTRACT   The use of AI-based technologies is increasingly widespread among students, particularly to facilitate assignments and understanding of course materials. Inappropriate use by students can have a negative impact on the future of the country. The objective of this research is therefore to examine the extent to which personal and environmental factors influence students' perceptions of learning outcomes when completing homework, considering the perceived ease of use of Chatbot AI as an intervening construct. In accordance with the TAM and UTAUT frameworks, perceived ease of use acts as an intervening variable that links the influence of personal and environmental factors on learning outcomes. A quantitative methodology, based on SEM-PLS, was used, involving 154 students from SMA/SMK in Surabaya and the surrounding areas. Based on gender, female respondents were 77.9% and male respondents were 22.1%. The validity and reliability of the research instrument were tested. The direct relationship between personal and environmental factors on students' perceived learning outcomes was found to be insignificant (p = 0.277), However, however, each factor is individually significant but the mediating effect is weak and insignificant. This means that students' personal and environmental factors alone do not improve their perception of their learning outcomes, as they feel that the results of AI chatbots do not reflect their own understanding. They consider learning successful only when it involves personal effort. However, when these factors influence perceived ease of use, this ease of use becomes the determining factor in how students evaluate their learning process.

Abstract

This study aims to explore the commognitive processes of a high-performing prospective mathematics teacher during mathematical problem posing by examining how the four commognitive components word use, visual mediators, routines, and narratives emerge across the orientation, connection, generation, and reflection stages. This study employed a qualitative descriptive approach. The participant was purposively selected based on obtaining the highest score on a mathematical problem-solving test. Data were collected through a problem-solving test, a problem-posing task, and semi-structured interviews. The data were analyzed using data reduction, data display, and conclusion drawing, while credibility was established through data triangulation. The findings revealed that all four commognitive components emerged throughout the mathematical problem-posing process. During the orientation stage, the participant represented mathematical ideas using appropriate mathematical symbols and terminology. During the connection stage, the participant established conceptual relationships by linking derivatives and integrals as inverse operations. During the generation stage, the participant formulated a more sophisticated mathematical problem involving exponential functions. During the reflection stage, the participant verified the solution through substitution and logical justification. These findings indicate that mathematical problem posing is not merely a procedural activity but a commognitive process in which conceptual understanding, mathematical communication, and reasoning interact dynamically. This study extends the application of the commognitive framework to mathematical problem posing and provides pedagogical insights for developing prospective mathematics teachers' problem-posing competencies.

Abstract

Penelitian ini bertujuan untuk mengelompokkan kualitas pendidikan kabupaten/kota di Jawa Timur menggunakan metode Fuzzy C-Means (FCM) serta menentukan jumlah cluster optimal dengan indeks validitas Partition Coefficient (PC). Data yang digunakan bersumber dari Badan Pusat Statistik Provinsi Jawa Timur dan mencakup indikator rata-rata lama sekolah, tingkat pendidikan tertinggi yang ditamatkan, angka partisipasi pendidikan, angka melek huruf, serta rasio murid terhadap guru. Pengujian dilakukan dengan variasi 2 hingga 5 cluster, dan hasil evaluasi menunjukkan bahwa dua cluster memberikan nilai PC tertinggi sehingga ditetapkan sebagai jumlah cluster optimal. Hasil pengelompokan membagi kabupaten/kota menjadi dua kelompok, yaitu wilayah dengan dominasi kualitas pendidikan dasar dan wilayah dengan dominasi kualitas pendidikan menengah, dengan masing-masing terdiri atas 21 dan 17 kabupaten/kota. Perbedaan antarcluster terutama dipengaruhi oleh rata-rata lama sekolah dan capaian pendidikan menengah. Secara keseluruhan, metode FCM dengan evaluasi PC mampu menghasilkan pengelompokan yang jelas dan relevan sebagai dasar perumusan kebijakan pendidikan di Jawa Timur.
