The objective of research was to determine the effect of slice thickness and frying temperature on the physical, chemical and sensorycharacteristics of pumpkin chips by vacuum frying method. Research used a Factorial Completely Randomized Block Design with 2 treatments and 3 replications. A factor (the slice thickness: 1, 2, and 3 mm) and B factor (frying temperature : 80, 90, and 100oC). The results showed that the slice thickness had significant effect on the crispy texture, yield, and water content of pumpkin chips. The temperature had significant effect on the lightness, chroma, crispy texture, yield, and moisture content. Interaction slice thickness and temperature had significant effect on the water content of pumpkin chips. A3B3 treatment (slice thickness 3 mm and frying temperature 100oC) was the best treatment with physical characteristic (yield 17.47%, crispy texture 183.6 gf, colour with 54.63% lightness, 42.17% chroma and 54.90o hue), chemical cha-racteristic (1.63% water content, 8.08% ash content) and sensory characteristics by scoring preferences 3.48 crispy texture, 3.2 flavour, 2 colour and 3.32 taste. A3B3 treatment had 1.58 dissoluble fiber content, 12.92 mg/mL IC50 antioxidant activity, 21.90 fat rate,1.46 ppm total carotene.

The purpose of this research was to observe the effects of threadfin breams surimi (Nemiptarus nematophorus) and mussel (Pilsbryoconcha exilis) to physical, chemical and sensory characteristics of nugget. This research used randomized block design (RBD) consisted of one factor treatment and three replications. Factor treatment consisted of combination ratio threadfin breams surimi and mussel 100% : 0%, 75% : 25%, 50% : 50%, 25% : 75%, 0% : 100%. The variables observed were physical characteristics (elasticity), chemical characteristics (moisture content, ash, protein, fat, carbohydrate, and iron) and sensory analysis on appereance, flavour, taste and texture of the final products. Different combinations of threadfin breams surimi and mussel had significant effect on elasticity (222.53 gf, 278.33 gf, 300.66 gf, 312.13 gf, 452.86 gf), ash content (3.26%, 2.51%, 2.23%, 1.63%, 1.45%), protein content (8.27%, 12.11%, 14.8%, 17.14%, 20.73%), carbohydrate content (17.32%, 14.34%, 11.11%, 8.42%, 3.5%), and iron (23.61%, 18.56%, 12.77%, 7.24%, 1.54%). Based on the results, the greater addition of surimi concentration caused the increasing value of elasticity, protein, and water content. While the greater addition of mussel concentration resulted on the increased value of ash, fat and iron. This research showed that the combination of 75% threadfin breams surimi and 25% mussel produced on nugget with the best characteristics.

ABSTRAK Pengolahan jahe merah dalam bentuk bubuk merupakan salah satu cara untuk mengawetkan hasil panen jahe merah yang memiliki kadar air yang tinggi. Pengolahan jahe merah dalam bentuk bubuk perlu dilakukannya pengeringan pada bahan sehingga mampu mengeluarkan kandungan air yang terdapat pada bahan. Dalam pengeringan suatu bahan suhu dan ketebalan merupakan hal berpengaruh pada pengeringan. Tujuan dari penelitian ini yaitu untuk mengetahui karakteristik pengeringan, sifat fisik bubuk jahe merah serta perlakuan yang menghasilkan kualitas bubuk jahe kering yang paling baik dengan variasi suhu dan ketebalan irisan selama pengeringan. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor dan tiga kali ulangan. Faktor yang pertama yaitu suhu pengeringan 50oC, 60oC, dan 70oC dan faktor kedua yaitu ketebalan irisan jahe merah 1 mm, 3 mm, 5 mm. Parameter yang diamati yaitu kadar air, kerapatan curah, sudut curah, indeks keseragaman, dan laju penurunan kadar air jahe merah. Dari hasil penelitian menunjukkan bahwa interaksi antar perlakuan suhu dan ketebalan irisan memberikan pengaruh yang signifikan terhadap parameter kadar air, kerapatan curah, sudut curah, dan laju penurunan kadar air jahe merah. Selanjutnya perlakuan terbaik diperoleh pada perlakuan (N3S5) dari jahe merah yang dikeringkan dengan ketebalan irisan 3 mm yang dikeringkan dengan suhu 50oC dengan nilai kadar air 10,05% bb, kerapatan curah 790Kg/m3, sudut curah 43,34o. ABSTRACT  Processing red ginger in powder form is one way to preserve the red ginger crop, which has a high moisture content. Processing of red ginger in powder form requires drying of the material so it can remove the water content in the material. In drying a material, the temperature and thickness influence drying. The purpose of this study was to determine the drying characteristics, the physical properties of red ginger powder and the treatment that produced the best dry ginger powder quality with variations in temperature and slice thickness during drying. The design used in this study was a factorial randomized block design (RBD) with two factors and three replications. The first factor is the drying temperature of 50oC, 60oC, and 70oC and the second factor is the thickness of the red ginger slices 1 mm, 3 mm, 5 mm. The parameters observed were moisture content, bulk density, angle of bulk, uniformity index, and rate of reduction in water content of red ginger. The results showed that the interaction between the temperature treatments and the thickness of the slices had a significant effect on the parameters of moisture content, bulk density, angle of bulk, and the rate of reduction in water content of red ginger. The best treatment was obtained in treatment (N3S5) of dried red ginger with a thickness of 3 mm slices dried at a temperature of 50oC with a moisture content value of 10.05% bb, bulk density 790Kg/m3, angle of bulk 43.34o.

The extraction of carrageenan by Eucheumma cottonii using siwalan neera as a solvent which contains pottasium 236mg per 100g and others mineral. Carragenan extract applied on pineapple jelly drink powder as a gelling agent by different concentration. This research was conducted into two stages by 3 times repitition. First, carrageenan extraction using a Factorial Randomized Block Design (RBD) consisting of 2 factors. The first factor is the ratio of seaweed with neera siwalan (S) (1:10, 1:20, 1:30) and second factor is extraction time (T) (60 minutes, 90 minutes, and 120 minutes). Extract of carrageenan was analyzed on yield, viscosity, gel strength, moisture content and ash content. The second stage is application of carrageenan extract on pineapple jelly drink powder (K) with carrageenan concentration differently (K) of 0.5%, 1%, 1.5%, 2%, 2.5%. The parameters analyzed in the second stage are viscosity, gel strength, syneresis, and organoleptic (taste, suction power, and mouthfeel). The results shows that there was a significant effect on the Siwalan neera ratio on the carrageenan produced on yield, viscosity, gel strength, water content. The best carrageenan at stage 1 was produced from the treatment of seaweed and neera siwalan ratio 1:30 with extraction time of 120 minutes (S3T3), namely yield 82.87%, moisture content 15.3%, ash content 15.97%, gel strength 102.95 g/cm2 and 5,3 cP viscosity. The addition of the best extract carrageenan to pineapple jelly drink and it was obtained the best result namely the addition of carrageenan 1% (K2) with viscosity of 2.3 cP, gel strength 8.6615 g/cm2, sineresis (24 hours) 0.9183%, sineresis (48 Hours) 3.5430%, and sineresis (72 Hours) 5.1905%, taste 3.3 (enough in tasting), suction power 3.75 (easy to suck) and mouthfeel 2.9 (enough to feel the gel).

Hasil pengamatan dianalisis menggunakan analisis keragaman ANOVA (Analysis of Variance) menggunakan Software Co-stat serta menggunakan uji lanjut Polynomial Ortogonal dan Duncan Multiple Range Test (p < 0,05). Perlakuan terdiri dari satu faktor yaitu lama pengeringan 120, 130, 140, 150, 160 dan 170 menit dengan suhu yang sama yaitu 50 oC. Hasil Penelitian menunjukkan bahwa lama pengeringan dalam pembuatan teh daun kersen memberikan pengaruh yang berbeda nyata terhadapkadar air, parameter organoleptik rasa, aroma (hedonik), rasa, aroma, warna (scoring) dan memberikan pengaruh yang tidak berbeda nyata terhadap aktivitas antioksidan, kadar abu, ekstrak dalam air dan organoleptik warna (hedonik). Hasil penelitian ini juga menunjukkan bahwa pengeringan selama 170 menit menghasilkan teh daun kersen dengan mutu terbaik untuk kadar air 3,05%, aktivitas antioksidan 88,60%, kadar abu 7,58% dan kadar ekstrak dalam air 7,58%, sedangkan untuk parameter organoleptik pada pengeringan 120 menit dengan warna (Kuning kehijauan),aroma (kersen agak khas) yang disukai serta  rasa (kersen pahit) yang tidak disukai oleh panelis.dengan warna,aroma yang disukai serta  rasa yang tidak disukai oleh panelis.This study aimed to determine the effect of drying time on the physico chemical properties of antioxidant activity, moisture content, ash content, extract content on water content and organoleptic (color, taste and aroma) of cherry leaf (Muntingia calabura L.) tea.
