Secara umum bahan pewarna yang sering digunakan terbagi atas pewarna alami dan sintetis (buatan). Pewarna sintetis lebih mudah ditemukan dipasaran dengan harga yang relatif lebih murah dibandingkan pewarna alami. Namun banyak sekali produsen yang menyalahgunakan pemakaian pewarna. Oleh karena itu dilakukan penelitian ini untuk mengetahui pengaruh limbah kulit buah manggis, kulit buah naga dan karmoisin terhadap kualitas terasi udang rebon (Acetes erythraeus) serta menghasilkan rancangan modul sebagai bahan ajar pada pembelajaran biologi kelas XII SMA. Penelitian ini terdiri dari dua tahap yaitu eksperimen dan perancangan modul pada bulan April-Mei 2021. Eksperimen dengan desain Rancangan Acak Lengkap (RAL) dan menggunakan 4 perlakuan dengan 3 kali ulangan. Perlakuan yang diberikan berupa perbedaan pewarna, pewarna alami (kulit buah manggis dan kulit buah naga) dan pewarna sintetis (karmoisin). Adapun perlakuan: P0(perlakuan tanpa pewarna), P1 (ekstrak pewarna kulit buah manggis), P2 (ekstrak pewarna kulit buah naga), dan P3 (pewarna karmoisin). Parameter yang diukur meliputi kadar protein, kadar lemak, kadar pH, kadar air, dan uji organoleptik. Hasil penelitian menunjukkan bahwa limbah kulit buah berpengaruh sangat nyata terhadap kualitas terasi udang rebon. Perlakuan yang terbaik adalah P1 (ekstrak pewarna kulit buah manggis) dengan kadar protein sebesar 20,15%, kadar lemak 0,08%, kadar pH 6,8, kadar air 23,97%, nilai uji kenampakan 8,9, nilai uji bau 8,6, nilai uji rasa 8,6, nilai uji tekstur 8,5 dan nilai hedonik 8,6.

Pembuatan tempe masih dilakukan secara tradisional dan dilakukan secara turun temurun dengan cara yang berbeda. Hal ini memungkinkan tumbuhnya perbedaan jumlah BAL pada setiap tempe. Tujuan penelitian yaitu untuk mengetahui perbandingan jumlah total BAL pada dua sampel tempe yang berbeda. Sampel yang digunakan adalah tempe D dan E yang berasal dari daerah Bekasi dan dari pengrajin yang berbeda. Metode yang digunakan adalah pengenceran bertingkat dengan spread plate. Penghitungan total BAL dilakukan pada cawan yang berisi 25-250 koloni dengan menggunakan rumus Total Plate Count (TPC). Identifikasi dilakukan secara makroskopis dan mikroskopis. Hasil penelitian menunjukkan bahwa sampel tempe D dan E memiliki total BAL berbeda yaitu berturut-turut 5,6x106 dan 1,2x107 CFU/g. Sampel tempe E memiliki total BAL tertinggi daripada sampel tempe D. Kedua sampel tempe memenuhi syarat standar bakteri probiotik yaitu 106 hingga 107 CFU/g.

This study aims to determine the antibacterial effect of essential oil concentrations of citronella emulgel preparations at concentrations of 10%, 20%, 30%, and negative control against S. aureus. The used method was agar diffusion by means of wells. Data were analyzed by One-Way ANOVA test and Post Hoc test in SPSS ver. 26. Lemongrass essential oil emulgel was proven to be able to inhibit the growth of S. aureus as evidenced by the inhibition zone formed. The diameter of the inhibition zones for the 10%, 20%, 30% concentrations were 5.367 mm, 7.867 mm, and 11.833 mm, respectively. While the emulgel base as a control was 0 mm. The results of the ANOVA test showed a significant value of 0.000<0.05, so there was a significant difference between the inhibition zone and the 95% confidence level. Based on the Post Hoc test, the inhibition of the three groups of emulgel formulations of citronella essential oil was significantly different from the control group. The three emulgel concentration groups proved to be significantly different, in which citronella essential oil emulgel with a concentration of 30% had the best antibacterial activity.
