ABSTRAKPenelitian ini bertujuan untuk mengetahui aktivitas antioksidan dan penghambatan ?-amilase pada kombinasi ekstrak air daun papasan dan daun sembung. Ekstrak dibuat dengan cara menyeduh serbuk daun papasan dan daun sembung dengan berbagai rasio (1:3, 1:1, dan 3:1). Penyeduhan dilakukan menggunakan 100 ml air mendidih (100?C) selama 5 menit. Hasil penelitian menunjukkan bahwa aktivitas antioksidan dalam menangkal radikal bebas DPPH tertinggi terdapat pada sampel kombinasi 1:3 yang dinyatakan dengan IC50 sebesar 1,58?0,06 mg/ml danaktivitas penghambatan ?-amilase tertinggi juga terdapat pada sampel kombinasi rasio 1:3 dengan nilai IC50 sebesar 1,29?0,02 mg/ml. Secara umum, semua kombinasi berpotensi sebagai minuman fungsional antidiabetes.Kata kunci: Daun papasan, daun sembung, aktivitas antioksidan, aktivitas penghambatan ?-amilase, ekstrak air.ABSTRACTThis study aims to determine the antioxidant and inhibition of ?-amylase activities of the combination of Coccinia grandis [L.] and Blumea balsamifera [L.] DC water extracs.

Background : Food safety remained as critical concern to immune-compremissed patient. Food safety assurance can be achieved through inhibition of pathogenic bacteria by physical treatment such as UV light radiation. However, a study regarding the effect of UV light on growth of pathogenic bacteria in contaminated liquid food are scarce.Objective : To determine the effectiveness of UV light on contamination of pathogenic bacteria in liquid food for immune-compremissed patient.Methods : Randomized design with two factor which were holding time for 60 and 120 minutes and radiation exposure (0, 5, 10 and 15 minutes). The data was analyzed using ANOVA Result : The viscosity and pH of liquid foods were 20 centipoise and 7,15 respectively. Radiation of UV light on contaminated food that have been incubated for 60 and 120 minutes at 37oC showed significant increase (1-2 log cycle) on growth of pathogenic bacteria.Conclusion : Radiation of UV light on contaminated liquid food were not effective to inhibit or kill pathogenic bacteria during holding time (60 and 120 minutes).

Background : Obesity is an excessive build up of fat in the body thus causing weight far above normal and it can improve the risk of degenerative dissease. Increasing food consumption of high protein, fiber and antioxidants couldÂ solve obesity problem. Soyabean milk waste product (okara) has high protein content but low economic value. Black rice flour has high antosianin, antioxidan and fiber. Functional food with main composition okara and black rice flour couldÂ be an alternative as aÂ functional food for this matter.Objective : To investigate right formulation of snack bar based on nutritional content andÂ sensory caracteristic for obese adolescent.Methods : This type of research is an experimental study using Complete Randomized Design with three treatments (Formula I, II, and III) and performed two replications (duplo). Nutritional value data between groupÂ was analyzed using Analysis of Variance (ANOVA) while sensory characteristic were tested by calculating hedonic quality test score.Result : Statistical analysis of nutritional content showed there were significantly different between group (p<0.05), but for antioxidants and phenolics levels and analysis of the sensory quality test were not significantly different (p>0.05). Formula I was most preferred and favored by the panelists with energy content 125.64 g, 9.89% water, 3.13% ash, 19.6% protein, 12.41% fat, 45.07% Carbohydrate, 16.44% total sugar, 15.58 % crude fiber, 208.35 mg/L GAEAC antioxidant, 1.01 mg/100 g anthocyanin and 61.05 mg/100 GAE phenolic.Conclusion : Formula I was the most preferred snack bar by panelist. This formula recommended for obese adolescent.

ABSTRAK Loloh sembung merupakan salah satu minuman tradisional bali yang memiliki efek kesehatan sebagai antihipertensi dan mengobati demam. Loloh sembung kurang populer di masyarakat karena rasanya yang pahit, sehingga perlu dilakukan pengembangan dan uji organoleptik dari loloh sembung. Tujuan dari penelitian ini adalah mempelajari karakteristik organoleptik loloh sembung yang telah dimodifikasi. Penelitian dilakukan dengan metode kuantitatif menggunakan kuesioner dan uji organoleptik yang meliputi rasa, warna, tekstur dan aroma. Analisis statistik menggunakan uji chi-square. Penambahan gula kelapa pada loloh sembung secara signifikan lebih disukai oleh panelis dibandingkan loloh sembung tanpa pemanis. Hasil korelasi Spearman menunjukkan bahwa usia panelis memberikan korelasi yang positif terhadap warna dan rasa loloh sembung masing-masing sebesar 0,046 dan 0,092. Sedangkan aroma dan tekstur loloh sembung memberikan nilai korelasi negatif sebesar -0,069 dan -0,011. Hasil ini menunjukkan bahwa usia panelis memiliki pengaruh kesukaan terhadap loloh sembung. Loloh sembung memiliki potensi untuk dapat dikembangkan sebagai welcome drink yang dapat dijadikan ikon suatu daerah wisata di Bali. Kata kunci: Loloh Sembung, Welcome Drink, Minuman Tradisional, Uji Organoleptic Abstract Loloh sembung is a traditional herbal Balinese drink that possess antihypertensive effect and use to cure fever. Loloh sembung is less popular in the society due to unpleasant taste and thus, it is necessary to develop and conduct an organoleptic test of loloh sembung. The purpose of this study was to study the level of preference from panelists on modified loloh sembung. Quantitative method was performed and the data was collected using questionnaires and organoleptic tests which including taste, color, texture and aroma.

Loloh sembung (Blumea balsamifera) is a functional drink that is widely consumed by Balinesse people and exhibit health-promoting effect. The purpose of this study was to identify GABA of loloh sembung which has physiological effect as antihypertensive. Proximate analysis was performed to determine nutritional value content of loloh sembung. Atomic Absorption Spectrophotometric (AAS) method was employed to determine potassium and sodium content, and identificatio of ɤ-aminobutyric acid (GABA) using Thin Layer Chromatography (TLC) method. In this study, water content of loloh sembung was 99.2324%, ash 0.0117. Fresh sembung leaves have water content 83.8112%, ash content 2.0617%, protein 0.9659%, fat 2.850%, and carbohydrate 10.3109%. Loloh sembung contained sodium, 51.65 mg/L and potassium 1353.10 mg/L. Subsequently, fresh sembung leaves contained sodium 579.72 mg/L and pottasium 1353.19 mg/L respectively. In this study, GABA was detected in loloh sembung and has promising prospect as antihypertensive-functional drink.

Citrus amblycarpa contain flavonoid-rich compounds and play important role in suppressing the conversion of angiotensin-converting enzyme 1 (ACE 1) to angiotensin-enzyme 2 (ACE 2). This study aimed to determine the bioactive compounds in the lime peel extract and their ability as in vitro ACE inhibitor activity. The lime peel extract was obtained by boiling the dried peel and dried leaves for 7 min at 70oC. The bioactive compound of the peel and the leaves were compared. The total phenolic, quercetin, rutin, and GABA were further quantified using spectrophotometer UV vis. The aqueous extract of C. ambylcarpa peel showed a high concentration of phenolic, quercetin, rutin, and GABA than that of the leaves extract. Furthermore, the peel extract at low concentration (0.0001 g/mL) has high efficiency in inhibiting ACE activity up to 133%. It can be concluded that the peel of C. amblycarpa is a good candidate for the management of hypertension.
