Brassica oleracea atau sayuran berasal dari Takengon mengandung banyak vitamin, karbohidrat, protein serta mineral. Umur simpan sayuran ini terbatas. Hal ini disebabkan karna kandungan kadar air yang tinggi mengakibatkan mudah rusak juga tidak tahan lama. B. oleracea sering diawetkan atau di fermentasi sebagai makanan sauerkraut di Negara Jerman. Namun di Indonesia belum banyak di produksi. Makanan ini memiliki sifat inderawi yang sangat khas menyerupai kimchi dari aroma dan cita rasanya. Penelitian ini bertujuan untuk mengidentifikasi produk kubis asam dari B. oleracea atau kimchi asal Aceh dengan penambahan merica terhadap variasi konsentrasi persentase garam selama fermentasi. Pengujian sifat fisika-kimia dilakukan di Laboratorium. Metode penelitian yang digunakan adalah analysis of variance (ANOVA) signifikan 5% dengan Rancangan Acak Lengkap (RAL). Faktor yang diuji adalah penambahan 1% merica pada konsentrasi garam K 2,25%, MG1 2,5%, MG2 7,5% dan MG3 12,5%. Hasil penelitian menyatakan perlakuan rekomendasi yaitu pada K 2,5% dan MG 2,25%. Rataan K 2,25% dengan sifat fisika-kimia susut bobot 20,75% dalam pH 3,56, TPT 7,75%, kandungan vitamin C 7,41 mg, kandungan kadar air 90,9%, serta asam laktat terkecil adalah 0,0096%. Namun rata-rata MG1 2,5% dengan sifat fisika-kimia susut bobot 20,05% dalam pH 3,69 TPT 7,55%, kandungan vitamin C 13,15 mg, kadar air 92,1%, serta asam laktat yang lebih kecil yaitu 0,0095%. Pemberian merica dalam konsentrasi garam yang berbeda terhadap kimchi asal Aceh berpengaruh nyata pada sifat fisika dan kimia. Berdasarkan hasil uji kesukaan dengan penambahan merica pada variasi garam terhadap panelis tidak terlatih diperoleh pada perlakuan K 2,25% dan MG1 2,5%.Kata kunci : Kimchi, B. oleracea, kubis, garam, sifat fisika-kimia.ABSTRACTBrassica oleracea or vegetables from Takengon were contain a lots of vitamins, carbohydrates, protein and minerals. The shelf life of these vegetables was limited. That case, it because the higher water content made easily damaged and it was not durable. B. oleracea was often preserved or fermented as a sauerkraut dish in Germany. But, in Indonesia not too much in production. This food has very distinctive sensory properties resembling kimchi in aroma and the taste. This study aims to identify vegetable cabbage products from B. oleracea or kimchi from Aceh with the addition of pepper at various percentages of salt concentration during fermentation. Furthermore, testing of physico-chemical properties was carried out in the laboratory. The research method used was analysis of variance (ANOVA) with a completely randomized design (CRD) with a significance of 5%. The factor tested was the addition of 1% pepper to a salt concentration of 2.25% K, 2.5% MG1, 7.5% MG2 and 12.5% MG3. The results of the study stated that the recommended treatment was 2.5% K and 2.25% MG.

Mathematical communication is a very important aspect that students must have if they want to succeed in their studies, so that mathematical communication really needs to be developed among students. In mathematical communication students can express ideas by communicating their mathematical knowledge both orally and in writing in the form of algebraic explanations, pictures, digrams or other mathematical models. This research aims to describe the level of students' abilities in mathematical communication. This research is a descriptive research with a quantitative approach. The results of the study revealed that overall the number of students who had written mathematical communication skills in the very good category reached 23.4%, the good category reached 19.1%, the fairly good category reached 25.5%, the less good category reached 21.3%, the bad category reaches 10.6%, and the average value of mathematical communication skills is in the pretty good category.

A quality learning process is influenced by the learning model used. A learning process that only listens to the teacher's explanation, does assignments, and focuses on books causes learning activities to become passive and there is a lack of student interaction. This has an impact on student learning outcomes. One model that involves students in learning is the Search, Solve, Create, and Share (SSCS) model. This research aims to determine the improvement in junior high school students' learning outcomes after implementing the SSCS learning model. This type of research is quantitative using Experimental Quasi. The subjects of this research were one experimental class, namely VIII-3, and one control class, VIII-4, SMP Negeri 3 Aceh Besar, each with 33 students. Data collection techniques use tests. The research results showed that the increase in learning outcomes for experimental class students was higher than that of the control class. The experimental class achieved 100% of the indicators of learning success/completion, namely ≥75% of students achieved a KKM ≥75 and there was an increase in student learning outcomes. The N-Gain test results show an increase in the moderate criteria, namely the experimental class is 0.69 and the control class is 0.49. Based on the results of the analysis, it can be concluded that the learning outcomes of students taught using the SSCS learning model are higher than the learning outcomes of students taught using the conventional learning model.
