The Borax Analysis Of The Crackers At Blauran Market, Salatiga City
Get PDFMisuse of chemicals, such as borax, as an additive in food is still common. This abuse is intended to increase elasticity and crispiness for longer in food products, even though borax is prohibited in the food industry. Some food products on the market that often contain borax are tofu, meatballs, noodles, and crackers. Research studies and mass media in several traditional markets in Indonesia have proven and verified the presence of borax in crackers. Based on this, we want to know whether there is the same thing in the distribution of crackers at Blauran Market, Salatiga City. Therefore, this research aims to quantitatively determine the status of borax in crackers sold at Blauran Market, Salatiga City, in 2023—a quantitative descriptive research method. Sampling used the purposive sampling method. The research design used was a completely randomised factorial design. The first factor is the type of cracker, consisting of four levels: gendar cracker brand X, gendar cracker brand Y, white eggplant cracker brand minute. Each treatment combination was repeated three times to obtain 24 experimental units. Quantitative test of samples using a UV-VIS spectrophotometer. Data processing using two-factor ANOVA with replication. The test results showed that the four brands of cracker samples contained >100 ppm borax. The highest borax content was in white eggplant crackers.Penyalahgunaan bahan kimia seperti boraks, sebagai bahan tambahan dalam pangan masih sering terjadi. Penyalahgunaan ini dimaksudkan untuk meningkatkan kekenyalan dan kerenyahan lebih lama pada produk pangan meskipun penggunaan boraks dilarang pada industri pangan. Beberapa produk pangan di pasaran yang kerap dijumpai mengandung boraks adalah tahu, bakso, mie, dan kerupuk. Studi penelitian dan media massa pada beberapa pasar tradisional di Indonesia telah membuktikan dan memverifikasi adanya boraks pada kerupuk. Berdasarkan hal ini kemudian ingin diketahui apakah terdapat hal sama pada distribusi kerupuk di Pasar Blauran, Kota Salatiga. Oleh karena itu, tujuan penelitian ini adalah untuk mengetahui secara kuantitatif status boraks dalam kerupuk yang dijual di Pasar Blauran, Kota Salatiga tahun 2023. Metode penelitian deskriptif kuantitatif. Pengambilan sampel menggunakan metode purposive sampling. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap Faktorial. Faktor pertama adalah jenis kerupuk, terdiri dari empat taraf: kerupuk gendar merk X, kerupuk gendar merk Y, kerupuk terung putih merk X, dan kerupuk terung putih merk Y. Faktor kedua adalah lama perendaman, terdiri dari dua taraf: 10 menit, dan 30 menit. Setiap kombinasi perlakuan dilakukan ulangan sebanyak tiga kali sehingga diperoleh 24 unit percobaan. Uji kuantitatif sampel menggunakan spektrofotometer UV-VIS. Olah data menggunakan Anova two-factor with replication. Hasil uji menunjukkan bahwa keempat merk sampel kerupuk mengandung boraks >100 ppm.

Pengaruh Perendaman Zat Pengatur Tumbuh Giberelin (GA3) pada Perkecambahan Benih Kopi Arabika (Coffea arabica L.) Varietas S795
Get PDFCoffee is one of the plantation commodities that has an important role in the national economy, especially as a source of foreign exchange because it has high economic value. The productivity of arabica coffee (Coffea arabica L.) in Indonesia in the 2019/2020 period decreased by 2.7% with a total production of around 95 million sacks. This study aims to determine the effect of gibberellin (GA3) on the germination of the arabica coffee bean variety S795. The experimental design was a completely randomized design factorial consisting of two factors with four replications for each treatment. The first factor was the plant growth regulator gibberellin concentration which consisted of 100 ppm (K1), 200 ppm (K2), and 300 ppm (K3). The second factor is the soaking time which consists of 12 hours (P1) and 24 hours (P2). The result showed that the interaction between GA3 concentration and soaking time had no significant effect on all observed parameters (germination percentage, germination rate, seedling height) in the germination of arabica coffee bean variety S795. Based on the table of average interactions between GA3 concentration and soaking time, it can be concluded that the K1P1 treatment with 12 hours of soaking time at a concentration of 100 ppm was the best treatment for the parameters of germination percentage, seedling height, and root length. The K2P1 treatment with 12 hours of immersion time at a concentration of 200 ppm was the best treatment for the germination rate parameter, namely 36.34 days.Coffee is one of the plantation commodities that has an important role in the national economy, especially as a source of foreign exchange because it has high economic value.
