Garlic have an activity as antifungal. Garlic extract need to be non spesific standarized to get consistent quality. Emulgel have hydrophobic or hidrophilic active substances because emulgel is a combination of emulsion and gel. This study aims to obtain the garlic extract emulgel formula which has good quality and good physical properties.The garlic extraction method maceration method with ethanol 96% as a solvent (1:7.5). Non spesific parameter of extract standardization were powder lost on drying, water content, ash content, acid-insoluble ash content, mass of extract spesification. Extract were standardized and then formulated in emulgel dosage form with 25% concentration of extract, then emulgel evaluated for physical properties include organoleptic test, homogeneity, pH, temperature stability, spreadability, stickiness, type of emulsion, and viscosity. The results showed rendemen of extract (8.90 ± 0.12)%,  lost on drying (6.85 ± 0.11)%, water content of extract (4.16 ± 1.4)%, ash content of powder (3.24 ± 0.02)% and extract (1.14  ±  0.03)%, acid-insoluble ash content powder (0.96 ± 0.02)% and extract (0.61 ±  0.07)%, the mass of extract spesification 1.028, and for the physical properties test of emulgel preparations obtained homogeneous emulgel, semisolid form, light brown color, smell of extract garlic, stable at 5ºC and 25ºC for 24 hours, pH 7, spreadability (2.49±0.12) g.cm.s-1, stickiness (61.99±5.81)seconds, type of emulsion o/w, viscosity(2.63±0.22) Pa.s.

Gelatin is an intermediate ingredient which is oftenly used in many field such as food, pharmacy, and cosmetics. It is usually extracted from pig and cow. Halal issue of gelatin sources and the outbreaks of mad cow diseases encouraged people to find an alternative sources of gelatin. One of the alternative sources of gelatin was duck bone. The aim of this research was to describe physicochemical properties of duck bone gelatin which is extracted by using acid extraction method as an alternative sources of halal gelatin. The extraction of duck bone gelatin used 5% concentration of HCl (hydrochloric acid). The extraction process consisted of four steps, they were degreassing, defating, demineralization, and acid extraction. The result showed that gelatin which was extracted from duck bone had these several characteristic: yield of 6.24%, pH 4.0, water content of 13.43%, ash content of 13.42%, protein content of 65.43%, and whiteness degree of 30.35%. Generally, gelatin which was extracted from duck bone had similar characteristic with commercial gelatin and SNI standard. Further researcher had been suggested to reoptimized extraction method in order to reduce ash content.

ABSTRAK. Penelitian ini bertujuan untuk mengetahui karakteristik fisiko kimia tepung ikan yang diberi tepung bawang putih (Allium sativum) pada masa penyimpanan yang berbeda. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap Pola Faktorial (RALF) dengan faktor A adalah tepung ikan dengan 3 level penambahan tepung bawang putih (0, 1, 2 dan 3%) dan Faktor B adalah lama penyimpanan tepung ikan (1, 2, 3 dan 4 minggu). Setiap perlakuan diulang sebanyak 3 kali. Variabel yang diamati dalam penelitian ini adalah Warna, Aroma, Kadar Air (KA), Kadar Abu (KA), Lemak Kasar (LK) dan Protein Kasar (PK). Hasil penelitian menunjukkan bahwa penambahan tepung bawang putih di dalam tepung ikan dengan level 0, 1, 2 dan 3% dengan lama penyimpanan yang berbeda berpengaruh nyata terhadap meningkatkan kadar air, tetapi menurunkan abu dan protein kasar. Interaksi antara level tepung bawang putih yang ditambahkan pada tepung ikan dan lama penyimpanan yang berbeda berpengaruh nyata (P˂0,05) terhadap kadar lemak kasar dan protein kasar. (Physicochemical characteristics of fish meal with garlic (Allium sativum) preservatives at different storage periods) ABSTRACT. This study aimed to determine the physicochemical characteristics of fish meal fed with garlic flour (Allium sativum) at different storage periods. The research design used was a Factorial Complete Randomized Design (RALF) with factor A being fish flour with 3 levels of adding garlic flour (0, 1, 2 and 3%) and Factor B was the storage time of fish meal (1, 2, 3 and 4 weeks). Each treatment was repeated 3 times. The variables observed in this study were colour, aroma, water content (KA), ash content (KA), crude fat (LK) and crude protein (PK). The results showed that the addition of garlic flour in fish meal with levels 0, 1, 2 and 3% with different storage periods significantly affected water content, but reduced ash and crude protein. The interaction between the level of garlic flour added to fish meal and the different storage times significantly (P˂0.05) on crude fat and crude protein.

Stick is type of pastry with a frying treatment with oil, usually made from wheat flour and tapioca. Banana flour is one of the flour products that can be used  making sticks because they are easily mixed into various preparations and enriched with nutrients. The general objective of this study was to determine the effect of adding white kepok banana flour to physical properties (hardness) and sensory sticks. The research method of banana sticks consisted of 4 treatments of adding white kepok banana flour which were 0, 10, 20 and 30 grams. Each treatment was repeated 6 times, resulting in 24 experimental units. The results showed that there was a significant effect of adding white kepok banana flour to physical characteristics (hardness) and sensory sticks. The best physical and sensory properties were found in the manufacture of sticks with the addition of 10 grams of white kepok banana flour with the results of proximate analysis of water content of 9.74%, ash content of 0.93%, fat content of 35.86%, protein 3.83% and carbohydrates 49 , 64%. The more white kepok banana flour is added, the resulting stick will be harder and produce a more brownish color, caramel aroma and a slightly sweet taste.

Gracilaria verrucosa merupakan salah satu jenis rumput laut yang berpotensi sebagai penghasil agar bernilai tinggi. Senyawa ini banyak digunakan sebagai pengental atau penstabil makanan dalam industri makanan. Jenis ini umumnya ditemukan di alam maupun dibudidayakan di tambak. Faktor fisik lingkungan dan parameter perairan dapat mempengaruhi kualitas agar yang dihasilkan. Informasi tentang kualitas agar dari rumput laut yang tumbuh di laut masih sedikit ditemukan, sehingga diperlukan penelitian. Tujuan penelitian ini untuk mengetahui pengaruh variasi konsentrasi NaOH terhadap kualitas agar G. verrucosa. Metode ekstraksi dilakukan dengan merendam sampel dalam larutan alkali (NaOH) hingga didapatkan agar, kemudian dikeringkan dan ditepung. Semua data dianalisis secara statistik yaitu normalitas, homogenitas dan two way ANOVA. Hasil ekstraksi agar didapatkan rendemen sebesar 18,44-20,35%, kadar air 13,22-15,06%, kadar abu 2,65-6,78% serta kekuatan gel 55,18-210,26 g/cm2. Hasil FTIR menunjukkan gugus galaktosa yaitu 3,6-anhidro-L-galaktosa yang menandakan sampel mengandung komposisi agar. Hasil menunjukkan bahwa konsentrasi NaOH berpengaruh nyata terhadap rendemen, kadar abu dan kekuatan gel (p<0,05) kecuali kadar air. Semakin tinggi konsentrasi NaOH maka rendemen, kadar air, kadar abu dan kekuatan gel akan semakin tinggi. Gracilaria verrucosa is one type of seaweed that has the potential to produce of high-value agar. This compound is much used as a food thickener or stabilizer in the food industry. This species is generally found in nature and cultivated in ponds. Factor of physical environmental and water parameter can affect the quality of produced agar. Information about quality of agar from seaweed that grows in the sea still rarely found, so research is needed. The purpose of this study was to determine the effect of different NaOH concentrations on the quality of agar G. verrucosa. The extraction method is done by soaking seaweed in an alkaline solution (NaOH) to obtain agar, then dried and turned into flour. All data were analyzed statistically with normality, homogenity and two way ANOVA. The results extraction of agar obtained yields 18,44-20,35%, water content 13,22-15,06%, ash content 2,65-6,78% and gel strength 55,18-210,26 g/cm2. FTIR results showed a galactose group of 3,6-anhydro-L-galactose which indicated the sample contained agar composition. The results showed that NaOH concentration significantly affected yield, ash content and gel strength (p<0,05) except water content. The higher concentration of NaOH therefore the yield, water content, ash content and gel strength would be higher.
