Abstract

The study of starter concentration effect and fermentation period of cocoa pulp on ethanol production has been carried out in order to determine the concentration of Saccharomyces cereviceae as a starter and optimum fermentation period to produce bioethanol from cocoa pulp. Variables in this research were S. cereviceae consentration of 6, 7, 8 and 9%; and fermentation periods 3, 5 and 7 days. The results showed that 5 days of fermentation period and the addition of S. cereviseae with a concentration of 9% obtained the highest ethanol content as much as 5.93% by the end of fermentation acidity of 6.0.

Abstract

The content of non fermented cocoa powder is phenolic compounds of polyphenols group which protecting skin from ultra violet radiation (UVB). This research aims to determine the concentration of non fermented cocoa powder that capable to protect the skin from UVB. This study used a complete randomized design with a treatment on the concentration of non fermented cocoa powder as the active ingredient of scrub cream. Scrub cream was made from non fermented cocoa powder in a variable concentration 2.5; 3.5; 4.5; 5.5% (w/w) with three replicates. The results showed that the viscosity were 36, 42, 49 and 70 dps, respectively. The four scrub cream have pH value above 5 which fulfilled the standard of SNI 01-3524-1994 and uncontained of Pb and Hg. The most panelists was preferred scrub cream with the concentration of non-fermented cocoa powder 3.5%, it gave moisture and smooth effect also lasted minimum for 180 minutes.

Abstract

Penelitian mutu soyghurt ditinjau dari jenis gula dan persentase gelatin telahdilakukan. Proses pembuatan soyghurt diawali dengan pembuatan susu kedelai denganvariasi penambahan jenis gula dan konsentrasi gelatin, kemudian dilanjutkan denganproses fermentasi menggunakan starter Streptococcus thermophillus dan Lactobacillusbulgaricus. Variabel pengamatan adalah derajat keasaman (pH), total padatan terlarut,kadar protein, total asam, dan uji organoleptik. Hasil penelitian menunjukkan bahwasoyghurt dari hasil fermentasi susu kedelai dengan penambahan sukrosa 7% dan gelatin5% (perlakuan A1B2) yang memenuhi SNI 01 – 2891 – 1992 dan yang paling di sukaioleh panelis dengan tingkat kesukaan terhadap rasa (5,0), aroma (3,3), warna (4,1) dantekstur (4,9).

Abstract

Epidermis of cocoa beans contain active compounds that are similar to the active compound in the cocoa pod husk. Epidermis of cocoa beans are suspected to contain active compounds such as  polyphenols, flavonoids, terpenoids/steroids, condensed or polymerized tannins such as catechins and anthocyanins. The bioactive compounds were known to have antibacterial properties on Streptococcus mutans types. The aim of this research were to produce natural active compounds from cocoa bean husk, which have antibacterial activity against Streptococcus mutans. Stages of the study consisted of powdering process of epidermis cocoa beans, extracting fat from epidermis cocoa beans powder, extracting of the antibacterial active compound, solvent evaporation of active compounds extracts from powdered cocoa beans husk, and testing of active compounds produced by Streptococcus mutans. Results showed that the minimum inhibitory concentration (MIC) of the cocoa bean husk extract againsts Streptococcus mutans on a half-day incubation period was 0.25% with an inhibitory diameter of 7.550 mm. While, a two- days incubation period was 0.25% with an inhibitory diameter of 9,900 mm and was bacteriostatic.Keywords: cocoa beans husk, maceration extraction, methanol, antibacterial, active components, Streptococcus mutans ABSTRAK. Kulit ari biji kakao mengandung senyawa aktif yang tidak berbeda jauh dengan kandungan senyawa aktif yang terdapat pada kulit buah kakao dan biji kakao itu sendiri. Kulit ari biji kakao diduga mengandung senyawa aktif polifenol, flavonoid, terpenoid/steroid, tanin terkondensasi atau terpolimerisasi seperti katekin dan antosianin. Senyawa-senyawa bioaktif tersebut diketahui memiliki sifat antibakteri jenis Streptococcus mutans.Tujuan penelitian ini adalah pemanfaatan kulit ari biji kakao sebagai sumber senyawa aktif yang memiliki aktivitas antibakteri terhadap bakteri Streptococcus mutans. Tahapan penelitian terdiri dari proses pembuatan bubuk kulit ari biji kakao, proses ekstraksi lemak dari bubuk kulit ari biji kakao, proses ekstraksi senyawa aktif antibakteri dari bubuk kulit ari biji kakao, proses penguapan pelarut ekstrak senyawa aktif dari bubuk kulit ari biji kakao, dan proses pengujian senyawa aktif yang dihasilkan terhadap Streptococcus mutans. Hasil penelitian menunjukkan bahwa ekstrak limbah kulit ari biji kakao berpotensi sebagai senyawa aktif antibakteri terhadap Streptococcus mutans. Konsentrasi hambat minimum (KHM) ekstrak kulit ari biji kakao terhadap bakteri Streptococcus mutans pada masa inkubasi satu setengah hari adalah 0,25% dengan diameter hambatan sebesar 7,550 mm dan masa inkubasi dua hari adalah 0,25% dengan diameter hambatan sebesar  9,900 mm dan bersifat bakteriostatik.  Kata kunci : kulit ari biji kakao, ekstraksi maserasi, metanol, antibakteri, komponen aktif, Streptococcus mutans
