The Effect of Comparison of Glucose and Sucrose Concentration on the Sensory and Chemical Quality of Jelly Candy (Eucheuma cottonii) ABSTRACT          The aims of this study were to determine the effect of different concentrations of glucose and sucrose on the sensory and chemical quality of seaweed jelly candy (Eucehuma cottonii). The study used a Completely Randomized Design (CRD) consisting of 4 treatments, namely : P1 (glucose : sucrose  = 45% : 0%), P2 (glucose : sucrose = 0% : 45%, P3 (glucose : sucrose = 30% : 15%), P4 (glucose : sucrose = 15% : 30%) with time three replications. Data from observations were analyzed using ANOVA (Analysis of Variance) at a level of 95%, if there is a real difference (P> 0.05) then a further test was performed with a DMRT (Duncan Multiple Range Test) tests at a 95% significance level. The results obtained show a real effect on sensory values which include color, texture, and taste but no significant effect on the scent. The best results for sensory assessment were found in the P4 treatment which has a taste value of 4.5, texture of 4.2, the scent of 4.0, and a taste of 4.2. The results showed the water content between 22.83%-17.01%, ash content of 0.11%-0.18%. and protein content of 3.75%-5.77%. Keywords: chemistry, glucose, jelly candy, seaweed (Eucheuma cottonii), sensory, and sucroseABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh perbedaan kosentrasi glukosa dan sukrosa terhadap kualitas sensori dan  kimia permen jelly rumput laut (E. cottonii).

The parts of the starfruit plant, namely the leaves and fruit of the starfruit, have the potential to be made into a functional drink. Efforts that have been developed to use the leaves and fruit of starfruit are herbal medicine. This study aims to determine the chemical properties (antioxidant capacity and tannin content), physical properties (color) and differences in the selling price of the herbal medicine for starfruit leaves with different leaf and fruit ratios. The research design used was a completely randomized design (CRD) with a factor of different ratios between leaves and fruit with two repetitions. Data were analyzed using ANOVA (Analysis of Variance). If there are differences, then proceed with the Duncan Multiple Range Test (DMRT). The results showed that the highest antioxidant capacity and tannin content of starfruit leaves were found in the ratio of 80 percent: 20 percent herbal medicine. The highest color brightness (L) is found in the herbal ratio 60 percent: 40 percent. The redness color (a -) is in the ratio 80 percent: 20 percent and the yellow color (b +) is the highest in the ratio of 60 percent: 40 percent herbal medicine.

AbstrakTujuan penelitian adalah untuk mengetahui kandungan fitokimia dan aktivitas antioksidan pada bulir cendol rumput laut Kappahycus alvarezii dengan penambahan tepung sagu yang diekstraksi dengan pelarut methanol. Ekstrak diperoleh dengan cara maserassi terhadap bulir cendol rumput laut dan tepung sagu. Uji fitokimia dilakukan untuk mengetahui keberadaan senyawa alkaloid, flavonoid, saponin, streroid dan triterpenoid. Aktivitas antioksidan bulir cendol Kappaphycus alvarezii diuji dengan metode DPPH ( 1-1 difenil -2 pikrilhidrazil). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari tiga perlakuan yaitu perlakuan R1S1 (RL : 10% TS : 90%), R2S2 (RL : 20%: TS : 80%), R3S3 (RL 30 % TS : 70%) dan ulangan sebanyak tiga kali. Data hasil pengamatan dianalisa menggunakan ANOVA (Analysis of Variance) pada taraf  95%, apabila terdapat beda nyata (P>0,05) maka dilakukan uji lanjut dengan uji DMRT (Duncan Multiple Range Test) pada taraf nyata 95%. Hasil penelitian mempelihatkan terdeteksi senyawa alkaloid, flavonoid, streroid dan triterpenoid sedangkan pada senyawa saponin tidak terdekteksi pada ekstrak metanol cendol Kappaphycus Alvarezii. Uji aktivitas antioksidan dengan metode DPPH menunjukan nilai IC50 terendah terdapat pada perlakuan R1S1 dengan jumlah IC50 652 ppm. Hal ini menunjukan bahwa adanya aktivitas antioksidan yang sangat lemah dari cendol  Kappaphycus alvarezii yang diekstraksi. Kata Kunci :    Aktivitas antioksidan, cendol, Kappaphycus alvarezii, Metroxylon sagus Rottb, fitokimia  AbstractThe aims  of this study was to determine the phytochemical content and antioxidant  on cendol seaweed (Kappaphycus alvarezii) with additions of sago flour (Metroxylon sagus Rottb.) extracted with methanol. Phytochemical tests were performed to determine the presence of alkaloids, flavonoids, saponins, triterpenoids and steroids. Antioxidant activity of seaweed cendol. Kaphaphycus alvarezii was tested by DPPH method (1-1- diphenyl-2-picrylhydrazl). This study used a Completely Randomized Design (CRD) which consists of three treatments R1S1( RL 10% : TS 90% ), R2S2 (RL 20% : TS 80%), R3S3 ( RL 30% : TS : 70%) and three times replication. Observation data were analyzed using ANOVA (Analysis of Variance) at the level of 95%, if there were significant differences (P> 0.05) then further testing was carried out with DMRT (Duncan Multiple Range Test) at 95% significance level. Phytochemical test showed there was compounds detected with alkaloids, flavonoids, triterpenoids and steroids. While the saponins compounds was not detected in methanol extract of Kappahycus alvarezi. The antioxidant activity by DPPH method showed that the high IC50 values is 652 ppm. That was indicated seaweed cendol from kappaphycus alvarezii has lower antioxidant activity. Key words:     Antioxidant activity, cendol, Kappaphycus alvarezii,Metroxylon sagus Rottb., phytochemical

ABSTRACT         The aim of this study was to determine the quality characteristics of seaweed Syrup (Eucheuma spinosum). This study used a Completely Randomized Design (CRD) consisting of 3 treatments, namely: P1 = 100 gr seaweed: 200 gr sugar: 3.5 L water: CMC 0.3 gr, P2 = 120 gr seaweed: 200 granulated sugar gr: water 3,5 L: CMC 0,3 gr, P3 = Seaweed 140 gr: sugar 200 gr: water 3,5 L: CMC 0,3 gr: with three times replications. Data from observations were analyzed using ANOVA (Analysis of Variance) at a level of 95%, if there is a significant difference (P> 0.05), further tests were carried out with the DMRT (Duncan Multiple Range Test) tests at a 95% confidence level. The results obtained showed that the concentration of seaweed (E. spinosum), water, and taste did not significantly affect the aroma and taste of seaweed syrup. The best treatment was in the treatment of P1 with a scent value of 3.46 with a rather like category, and P1 for a taste of 3.46 with a somewhat like category. The chemical value of seaweed syrup is the value of water content ranging from 38.96% -43.21%, ash content ranges from 0.82-1.34%. Keywords: Syrup, seaweed (Eucheuma spinosum), chemistry and sensoryABSTRAKTujuan penelitian ini adalah untuk mengetahui Karakteristik Mutu Sirup Rumput Laut (Eucheuma spinosum). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan yaitu : P1 = Rumput laut 100 gr : gula pasir 200 gr : air 3,5 L : CMC 0,3 gr, P2 = Rumput laut 120 gr : gula pasir 200 gr: air 3,5 L : CMC 0,3 gr, P3 = Rumput laut 140 gr : gula pasir 200 gr : air 3,5 L : CMC 0,3 gr : dan ulangan sebanyak tiga kali. Data hasil pengamatan dianalisa menggunakan ANOVA (Analysis of Variance) pada taraf 95%, apabila terdapat beda nyata (P>0,05) maka dilakukan uji lanjut dengan uji DMRT (Duncan Multiple Range Test) pada taraf kepercayaan 95%. Hasil penelitian yang diperoleh menunjukkan bahwa Kosentrasi rumput laut (E. Spinosum), air dan rasa berpengaruh tidak nyata terhadap aroma dan rasa sirup rumput laut. Perlakuan terbaik terdapat pada perlakuan P1 dengan nilai aroma sebesar 3,46 dengan kategori  agak suka, dan P1 rasa 3,46 dengan kategori agak suka. Nilai kimia sirup rumput laut yaitu nilai kadar air berkisar 38,96%-43,21%, kadar abu berkisar 0,82-1,34%.Kata kunci: Sirup, rumput laut (Eucheuma spinosum), kimia dan sensori
