Abstract

"Dumbo" catfish is a type of catfish that is widely consumed and cultivated. It includes the mutiara catfish (Clarias gariepinus) growing relatively fast and having a fairly high nutritional content. It can be used as a flavor enhancer in the form of instant broth powder. This research aims to determine the formulation and best quality of instant catfish broth powder products using the Spray Drying method as a natural flavor enhancer that the public likes and follows the Indonesian National Standard. This research was started by sampling the fish and separating the meat. Then, an analysis of fish meat, including a proximate test, was prepared and continued with making broth with different recipes based on the added weight of catfish meat (in percentage) with several spices used in several formulations: 75% (F1), 70% (F2), 65% (F3), 60% (F4) and 55% (F5) by boiling and mixing all the supporting ingredients according to the predetermined formulations. Next, the drying process was carried out using the Spray Drying method, followed by an organoleptic test to obtain a chosen formula and, finally, the quality of the instant Mutiara catfish broth powder product was tested. The instant powder (F4) was the selected product based on the organoleptic test, because this formula is the most preferred product by the panelists. The results of the analysis of physical, chemical, microbiological characteristics complied with SNI 01-4218-1996 concerning broth powder. In addition, the shelf life of this product with metallized plastic packaging was 1,028.24 days.Keywords: Broth powder; Catfish; Characterization; Shelf life

Abstract

Increased human activities will cause various problems, one of which is water pollution in water sources because it receives a pollution load that exceeds its carrying capacity. In the context of environmental conservation, the government has set quality standards for liquid waste produced by various industries and other activities in a Decree of the State Minister for the Environment. COD (Chemical Oxygen Demand) is one of the most important parameters in wastewater quality standards. This study aims to validate the COD analysis method which refers to COD Thermoreactor System (LOVIBOND brand) at Pakuan University Service Laboratory, to ensure the validity of COD analysis results at Pakuan University Service Laboratory. Spectrodirect COD analysis method provides results that meet the requirements of accuracy, precision, LOD, and LOQ which is quite good. The results of the Coefficient of Variation give good results with a value of 1.8841% indicating the accuracy of the analysis method is good. The accuracy parameter also gives good results and meets the requirements with a% recovery value of 98.70351%. Overall, it can be stated that the spectrodirect analysis method tested is an accurate, precise, simple, and economical method for determining COD levels

Abstract

Dragon fruit skin, waste material (dragon fruit waste), will have a profitable sale value if it can be used as a food raw material. Dragon fruit skin waste contains relatively high dietary fiber so it can be used as a food raw material. This study aims to utilize dragon fruit skin waste for the manufacture of dragon fruit skin flour as an alternative food source. Some tests are made on white-meat dragon fruit skin, red-meat dragon fruit skin and super red dragon fruit skin. The preliminary study is the soaking of the three types of dragon fruit skin in two solutions, namely 0.1% sodium citrate and 0.1% sodium metabisulfite to prevent the browning effect on flour. Dragon fruit skin flour from the soaking with both solutions is then characterized physically, including its texture, color, flavor and rendement. The best physical characterization is followed by chemical characterization, including the contents of  water,  ash, protein, fat, carbohydrate, dietary fiber, minerals (Fe, Na, K, Ca and P), and also microbiological characterization of Escherichia coli, molds and Bacillus cereus. The chemical and microbiological characterization shows that the red-meat dragon fruit skin flour has better results than the white-meat and super red dragon fruit skin flour does. The red-meat dragon fruit skin flour contains 8.80% water, 0.20% ash, 2.35% fat, 7.69%, protein, 68,29% carbohydrate and 28,72% dietary fiber as well as 4.40 mg K, 8.76 mg Na , 0.65 mg Fe , 10.20 mg Ca and 32.58 mg P. Keywords: Waste, Dragon Fruit Skin, Dragon Fruit Skin Powder, Alternative Food Source

Abstract

Acne is a skin disease that causes humans to lack confidence in carrying out activities. Besides being sick, acne worsens the beauty of human skin. The cause of acne is gram-positive bacteria, namely Staphylococcus aureus and Propionibacterium acnes. Many studies reported that Coffea canephora L can inhibit the growth of bacteria. The objective of this study is to establish the minimum inhibitory concentration (MIC) of the ethanol extract of robusta coffee seeds in inhibiting the growth of Staphylococcus aureus and Escherichia coli. The ethanol extract of C. canephora L seed was obtained by maceration method using 96% ethanol. The extract obtained was evaluated for its antibacterial activity using the agar diffusion method with perforation techniques. The extract was divided into five various concentrations (50%, 25%, 12.5%, 6.25%, and 3.125%). The results of this study indicated that the ethanol extract of coffee seeds with a concentration of 50% resulted in a wider diameter of the zone of inhibition of bacterial growth in S. aureus, 30.00 mm compared to P. acnes, 26.22 mm. The MIC of ethanol extract for S. aureus at 3.00%  while P. acnes was 6.00%.  In conclusion, the antibacterial effect of the ethanol extract of coffee seeds at 50% concentration was stronger against S. aureus bacteria than P. acnes. The greater the concentration of the extract, the wider the resulting inhibition zone.

Abstract

Tongkol jagung mempunyai kandungan silika yang cukup tinggi, yaitu 67,41% dari total abunya yang memungkinkan untuk dimanfaatkan untuk pembuatan komposit eugenol-silika gel. Penelitian ini bertujuan mempelajari pembuatan komposit eugenol-silika gel dengan bahan dasar abu tongkol jagung menggunakan metode sol gel, diikuti dengan analisis daya serap air dan aktivitas antibakteri terhadap E. coli dan S. aureus. Komposit eugenol-silika gel ini dikarakterisasi menggunakan Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) dan Thermogravimetric Analysis (TGA). Hasil karakterisasi dengan FTIR menunjukkan bahwa sintesis komposit eugenol-silika gel berhasil dilakukan. Analisis menggunakan XRD menunjukkan bahwa komposit eugenol-silika gel memiliki bentuk amorf. Karakteristik mikrostruktur menggunakan SEM menunjukkan permukaan yang tidak merata dan terdapat gumpalan (cluster) yang menandakan adanya bentuk butiran-butiran yang beragam berbentuk bulat atau globular pada permukaan komposit eugenol-silika gel. Analisis termogravimetri yang dilakukan sampai suhu 600 °C menunjukkan total prosentase pengurangan massa komposit eugenol silika-gel sebesar 13,10%. Daya serap air komposit eugenol-silika gel memiliki nilai persentase yang lebih tinggi dibandingkan dengan silika gel food grade. Akan tetapi, komposit eugenol-silika gel tidak memiliki aktivitas antibakteri terhadap E. coli dan S. aureus.Synthesis and Characterization of Eugenol-Silica Gel Composite from Corn Cob Ash and Analysis of Antibacterial and Water Absorption. Corn cobs have high silica content, specifically 67.41% of the total ash, possibly used for eugenol-silica gel composite manufacture. This study aims to synthesize eugenol-silica gel composite with corn cob ash as the base material by sol gel method, followed by analyzing water absorption and antibacterial activity against E. coli and S. aureus. The method used is the sol-gel method. This eugenol-silica gel composite was characterized using Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Thermogravimetric Analysis (TGA). The characterization results by FTIR showed that the synthesis of the eugenol-silica gel composite was successfully carried out. Analysis using XRD showed that the eugenol-silica gel composite had an amorphous form. Microstructural characteristics using SEM showed an uneven surface and clusters indicating the presence of various globular or spherical shapes on the surface of the eugenol-silica gel composite. Thermogravimetric analysis carried out until a temperature of 600 °C showed the total percentage reduction in mass of the eugenol silica-gel composite was 13.10%. The water absorption of eugenol-silica gel composite has a higher percentage value than food-grade silica gel. However, eugenol-silica gel composite has no antibacterial activity against E. coli and S. aureus.
