Abstract

Rice bran contained important bioactive phytochemical components such as tocopherol, tocotrienol, and γ-oryzanol, and one of the components of γ-oryzanol is stigmasterol. The aim of the present study was to isolate and identify stigmasterol in native red rice bran extract. The isolation of sterol from red rice bran extract was performed by using Thin Layer Chromatography (TLC) and followed by identification by Fourier Transformed Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance (NMR). The TLC single spot originated from crude red rice hexane extract was observed at 365 nm UV and the FTIR spectra analysis result showed that the OH group was indicated by 3436,9 cm-1 absorption. While absorption regions of 2931,6 to 2852,5 cm-1 indicate the presence of single bond CH. The data of 1H-, 13C- and 2D-NMR of rice bran sterol indicated that the single spot obtained in TLC analysis was stigmasterol. It can be concluded that native red rice variety of North Sulawesi contained stigmasterol and potential as a native antioxidant sources.

Abstract

Essential oil of nutmeg (Myristica fragrans houtt) is one of the many potentials of nutmeg that has a high economic value although in North Sulawesi it has not been exploited to its full potential. This research was conducted to compare the yield and properties of Nutmeg oil extract from the seeds and mace of Talaud and North Minahasa-North Sulawesi. The oil extract was obtained by distillation and was further characterized in terms of color, solubility in ethanol, density, optical rotation, refractive index. Results of this research exhibited that oil of the mace of nutmeg from Talaud had a lighter appearance in color compared to that from North Minahasa, while the density of oil extracted from North Minahasa was more densed compared to Talaud in both seed and mace (0.923 and 0.938 respectively at 25°C). The reflective index of nutmeg oil from North Minahasa was slightly higher than of Talaud both from seed and mace (1.4834 and 1.493 at 25°C), while the optical rotations of oil extracted from the mace were between +6.90° to +9.80° and from the seed were +20.73° to +22.30°.

Abstract

Bioflok adalah teknik budidaya ikan untuk mengelola lingkungan budidaya dengan memanfaatkan mikroorganisme untuk meningkatkan penggunaan pakan dan sisa hasil metabolisme dengan penambahan sumber karbon organik. Penelitian ini bertujuan untuk mengetahui ketahanan hidup bibit ikan mujair (Oreochromis mossambicus) dan nilai parameter kimiawi lingkungan pada media pemeliharaan bioflok dengan debris daluga (Crytosperma merkusii) sebagai sumber karbon. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan yang dilakukan adalah tanpa bioflok, C:N=15, C:N=20, dan C:N=25. Hewan uji ikan mujair dengan panjang rata-rata 5,5 cm di tebar 10 ekor setiap ember. Parameter yang diamati adalah kualitas air yang meliputi suhu, pH, konduktivitas, dan redoks dan Survival Rate (SR) ikan mujair. Dari hasil penelitian diketahui bahwa perlakuan terbaik pada C:N=25 dengan persentase SR tertinggi yaitu, 86,67%. Kualitas air selama penelitian ada pada kondisi optimal di setiap perlakuan.

Abstract

Mujair fish (Oreochromis mossambicus) is a freshwater fish that is commonly consumed. This is due that they are easily found and obtrained and with a price in fresh markets that are relatively cheap. Unfortunately, this fish happens to be a very perishable commodity, due to it’s sensitiveness to spoilage because of its high protein content and moisture content. Pangi seeds (Pangium edule) is known to contain tanines, natural polyphenols that inhibits microorganisms through their cell wall permeability. The purpose of this research was to test the potential of pangi seeds crude extract as natural pangi seed toxiti preservatives on mujair fish, shelf life potential on mujair fish. This was achieved by marinating the fish in crude pangi seed extracts at concentrations of 0% (control), 5% and 10% and then store for 4 days at room temperature. Parameters tested on this research includes cyanide identification BSLT toxicity testing and fish spoilage (degradation) through protein changes and pH. Results of this research indicated that pangi seeds crude extract does not contain any cyanide of whatsoever, pangi seed crude extract toxicity testing indicated thatit was not toxic to a concentration of 128233mg/L, meanwhile protein analysis indicated that the optimum concentration of pangi seed crude extract to inhibit fish spoilage is 10% while in terms of pH degradation, the optimum concentration was 5%.
