Abstract

Standardisasi kualitas produk menjadi tantangan utama dalam produksi Sinonggi, makanan tradisional khas Sulawesi Tenggara. Penelitian sebelumnya telah mengidentifikasi bahwa kegagalan proses gelatinisasi disebabkan oleh ketidaktepatan suhu air dan rasio volume yang selama ini hanya mengandalkan intuisi subjektif pembuatnya. Penelitian ini bertujuan untuk mengembangkan model matematis menggunakan Logika Fuzzy (Fuzzy Logic) guna menentukan presisi takaran dan kontrol suhu dalam pembuatan Sinonggi. Metode yang digunakan adalah pengembangan Fuzzy Inference System (FIS) metode Mamdani dengan dua variabel input: massa pati sagu dan suhu air, serta satu variabel output: volume air panas. Tahapan penelitian meliputi fuzzifikasi variabel berdasarkan data pakar, pembentukan basis aturan (rule base), dan defuzzifikasi. Hasil penelitian menunjukkan bahwa model fuzzy yang dikembangkan mampu menerjemahkan intuisi linguistik juru masak tradisional menjadi algoritma matematis yang presisi. Implementasi model ini menghasilkan Sinonggi dengan tekstur yang konsisten (kenyal dan bening) serta menurunkan risiko kegagalan produksi secara signifikan. Algoritma ini direkomendasikan sebagai dasar pengembangan teknologi tepat guna bagi UMKM kuliner lokal.

Abstract

This study aims to investigates the determinants of student success in hologram-enhanced geometry classrooms by examining the mediating role of teachers' Technological Pedagogical Content Knowledge and Skills (TPCK-S). Employing a Sequential Explanatory Mixed-Methods Design, this research analyzed data from 12 secondary mathematics teachers (purposively sampled) and 248 Grade 8 students from four public schools implementing the national 'Kurikulum Merdeka' in a provincial capital city in Indonesia. Quantitative analysis utilizing Spearman’s rank-order correlation revealed a robust positive revealed a robust positive relationship (r = 0.78, p = 0.002) between teacher performative skills and student deep learning achievement. To explain this statistical link, a qualitative phase involving classroom observations and semi-structured interviews was conducted with four teachers selected through extreme case sampling. The findings illuminate a "Flywheel Mechanism," demonstrating that high-TPCK-S teachers act as "Pedagogical Orchestrators" who effectively transfer "Cognitive Agency" to students. This agency characterized by student-led hypothesis testing and spatial reasoning is identified as the primary driver of deep conceptual understanding. Conversely, low TPCK-S results in passive student observation. These results suggest that educational development must shift focus from mere technology procurement to the cultivation of teachers' orchestration skills.
