Abstract

Butterfly pea (Clitoria ternatea L.) is an indigenous Indonesian flower that is usually consumed as a natural ingredient in herbal drinks and nutraceutical products. It contains several bioactive compounds that showed strong antioxidant activity to neutralize free radical compounds from foods. The aim of this study was to identify the bioactive compounds, antioxidant capacity and the organoleptic characteristics in the brewed of dried butterfly pea. The experimental design of this study used a completely randomized design with two factors: 1) dried butterfly pea content in water : 0,5; 1,0; dan 1,5 (g/200 ml) and 2) brewing levels (1, 2, and 3 times). The phytochemical screening analysis revealed that the brewed butterfly pea contained bioactive compounds such as flavonoids, tannins, saponins, steroids, and triterpenoids. The longer dried butterfly peas soak in water showed the higher level of total anthocyanin content, total phenolic compounds, and antioxidant activity. Organoleptic analysis showed significantly effect of the colour but not the odour or flavour of the brewed dry butterfly pea.

Abstract

Previous research used used cooking oil as a handsoap which has a strong inhibition of bacterial growth but still causes dry and slightly itchy skin, so this research was perfected by adding olive oil as a base. The problem is, which formulations of used cooking oil and olive oil in handsoap can inhibit bacterial growth and moisturize the skin, as well as their quality against organoleptic tests, irritation, and high foam. The purpose of this study was to determine the formulation of handsoap which has strong antibacterial properties, moisturizes the skin, and determines its quality against organoleptic tests, irritation, and high foaming. The composition of used cooking oil and olive oil used was 125 gr : 125 gr (Formula 1), 150 gr : 100 gr (Formula 2), 175 gr : 75 gr (Formula 3), and 200 gr : 50 gr (Formula 4). The making of this handsoap uses an experimental method. Testing the zone of inhibition of bacterial growth used the in vitro method, organoleptic testing was done through descriptive tests, and testing for PH, Irritability, and Foam Height was through descriptive tests using observational analytic methods. The results of this study are that this handsoap has a strong ability to inhibit bacterial growth, can moisturize the skin, is not irritated, and has a lot of foam, but has a large PH which is not in accordance with SNI so that it cannot be used by the public

Abstract

Eggs are livestock products that have a big contribution in overcoming nutritional problems in society. Generally, eggs only last for two weeks if stored at room temperature. Therefore preservation efforts are very important to maintain the quality of the eggs, so that the quality and nutritional value of the eggs remain good and do not change the taste, smell, color and contents. One way is to preserve them by salting and adding red ginger. Red ginger contains antioxidants, antimicrobials and essential oils that can preserve and give a distinctive aroma. The aim of this study was to determine the effect of adding red ginger (Zingiber officinale Rubrum variety) on the characteristics of salted eggs. The study used a completely randomized design (CRD) with 5 treatments, namely P0: 0% red ginger, P1: 20% red ginger, P2: 30% red ginger, P3: 40% red ginger, and P4: 50% red ginger with 5 times test. The results showed that the characteristics of salted eggs with the addition of 30% red ginger got the highest score in the hedonic method organoleptic test.

Abstract

Daun cincau hijau yang telah dipanen mudah rusak. Bubuk daun cincau didapatkan dari hasil pengeringan dan pengecilan ukuran. Penelitian ini bertujuan untuk mengetahui perbedaan pada karakteristik fisik (rendemen, sineresis, tekstur, warna, kecepatan pembentukan gel), karakteristik kimia (pH, kadar air, kadar abu, dan serat kasar) dan sensoris gel dari daun cincau hijau segar dengan gel dari bubuk daun cincau hijau (Cyclea barbata Miers). Penelitian dilakukan di Laboratorium Rekayasa Proses Pengolahan Pangan dan Laboratorium Kimia dan Biokimia Pangan Universitas Semarang pada bulan Juni 2022. Rancangan percobaan menggunakan Rancangan Acak Lengkap (RAL), 2 perlakuan, 10 ulangan dan dianalisis dengan independent sample T-Test. Kesimpulan menunjukkan nilai signifikansi kadar air, kadar abu, sineresis, pH, kecepatan pembentukan gel, springiness, sensoris warna maupun spektrofotometri, aroma, rasa dan kekokohan gel dari daun cincau hijau segar dengan gel dari bubuk daun cincau hijau (Cyclea barbata Miers) kurang dari 0,05 (Sig. 2-tailed) yang artinya ada perbedaan yang signifikan. Sedangkan pada rendemen, serat kasar, hardness dan gumminess menunjukan nilai signifikansi lebih dari 0,05 (Sig. 2-tailed) yang artinya tidak terdapat perbedaan yang signifikan.

Abstract

Cookies is one of the wheat-based snack product with increasing rate of consumption by years. Wheat flour used in Indonesia is fully imported. Local crop product such as brown rice flour with respective nutritional aspect can be utilized for wheat substitution. Addition of spinach as green leafy vegetable with numerous nutrients gives more functional value to the product.   This research aimed to investigate the acceptability (sensory properties) and nutritional content of brown rice flour cookies with the addition of green spinach. Four formulations made with ratio of brown rice and green spinach which were 100:0, 90:10, 85:15, 80:20. There were significant differences in protein, fat, and carbohydrate content among the four cookies samples There were significant differences in color appearance and taste between all samples. The best treatment is at the ratio of brown rice flour 90: green spinach 10, containing moisture content of 3.83%; ash content 1.48%; protein content 10.97%; fat content 31%; carbohydrates 52.7%; and crude fiber content of 17.3%.

Abstract

Indonesia is the 4th largest coffee producer after Brazil, Vietnam and Colombia. The largest Arabica coffee production center in Indonesia is in Central Aceh District. Biophysical factors, such as soil conditions, climate and altitude, which are planted at an altitude of 1,000-1,400 meters above sea level are the factors that make Gayo Arabica coffee green bean known as a special coffee that has a strong coffee taste and characteristics. Coffee has a lot of chemical content in it, for example the content of chlorogenic acid and caffeine. Physicochemical analysis of the samples included moisture content, ash content, fat content, protein content, caffeine content, phenol content, acidity level (pH), and specific volume. This data analysis used a completely randomized design with 3 replications comparing coffee from each coffee processing using five types of storage packaging for 4 months. Semi-wet processed coffee has the characteristics of moderate acidity, sweet taste, medium to low. Keywords: Gayo Arabica, semi washed, green bean, storage, Packaging

Abstract

Papaya (Carica Papaya L.) IPB 9 (calina) variety is a papaya fruit that has thick, sweet flesh and very high fruit productivity. During the transportation process of papaya, mechanical damage (bruises, abrasions, weight loss) and physiological damage often occur, which can cause papaya decrease in quality during storage before consumption. The purpose of this study was to determine changes in the quality of papaya after 2-hour transportation simulation. The research design used a randomized block design (RAK) with the treatment of the position of the fruit in the packaging, which was stored horizontally (KS1) and vertically (KS2) during the transportation simulation process. Papaya hat has been simulated for transportation is stored at 18–20oC for 12 days. Quality of papaya weight loss stored for 12 days for KS1 reached 7.34% and KS2 reached 7.43%. Hardness quality of papaya  stored for 12 days for KS1 is 0.84 kgf, and for KS2, it is 0.76 kgf. Quality of papaya skin color after 12 days of storage decreased the freshness of the papaya fruit, but it was still fit for consumption. Total dissolved solids content after being stored for 12 days for KS1 reached 11.45% and KS2 reached 11.32%.
