Penelitian ini bertujuan untuk mengetahui pengaruh suhu dan waktu pengeringan terhadap karakteristik kimia dan sensorik teh daun bambu Tabah. Penelitian ini dirancang menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor, yaitu faktor suhu pengeringan (50o C dan 60o C) dan faktor waktu pengeringan (1 jam, 2 jam, dan 3 jam). Perlakuan diulang tiga kali untuk mendapatkan 18 unit percobaan. Parameter yang diamati adalah kadar air, pH, total asam, total fenol, dan organoleptik. Hasil penelitian menunjukkan bahwa interaksi suhu dan lama pengeringan daun teh bambu Tabah memiliki pengaruh berbeda nyata terhadap kadar air, pH, total asam, total fenol, warna, penerimaan keseluruhan, tetapi tidak memiliki pengaruh yang berbeda nyata terhadap aroma dan rasa, dengan perlakuan terbaik ini, kadar air, pH, asam total, fenol total, warna, aroma, rasa dan penerimaan keseluruhan ditemukan kadar air 6,881%, pH 6,6, total asam 0, 73%, total fenol 84,01mg / 100g, warna 4,33, aroma 4,40, rasa 3,93, dan penerimaan keseluruhan 4,07.   This study aimd to determine the effect of temperature and drying time on the chemical and sensory characteristics of Tabah bamboo leaf tea. This study was designed using a Completely Randomized Design (CRD) with two factors, namely the drying temperature factor (50oC and 60oC) and the drying time factor (1 hour, 2 hours, and 3 hours). The treatment was repeated three times to obtain 18 experimental units. The parameters observed were water content, pH, total acid, total phenol, color, aroma, taste, and overall acceptance tested organoleptically. The results showed that the interaction of temperature and duration of drying of Tabah bamboo tea leaves had significantly different effects on water content, pH, total acid, total phenol, color, overall reception, but did not have a significantly different effect on aroma and taste. with this combained best treatment, the water content, pH, total acid, total phenol, color, aroma, taste and overall acceptance were found water content 6,881 %, pH 6,6, total acid 0, 73%, total phenol 84,01mg / 100g,color 4,33, aroma 4.40, taste 3,93, and overall acceptance 4,07.

This research aimed to determine the effect of drying temperature and time on antioxidant activity and sensory properties of herbal tea bag of rambusa leaf and to obtain the optimum temperature and drying time that can produce rambusa leaf herbal tea bag with the highest antioxidant activity and the best sensory properties. This research used a completely randomized factorial design with two treatments namely, drying temperature (40°C, 50°C, 60°C) and drying time (3 hours, 3.5 hours, 4 hours). There were 9 factorial combinations, each combination was repeated 2 times. The data obtained were analyzed by analysis of variance. If the treatment had a significant effect, it would be followed by the Duncan test. The results showed that the drying temperature and time treatment had a significant effect (P<0.05) on antioxidant activity, total phenols, total flavonoids, total tannins, water content, color (scoring test), and taste (scoring test), but no significant effect (P>0.05) on the extract content in water, color (hedonic test), taste (hedonic test), and overall acceptance. The results showed that drying temperature of 60°C with a drying time of 3 hours had an optimum drying temperature and time to produce herbal tea bag of rambusa leaf with antioxidant activity of 46.28%, total phenol level of 4.14 mg GAE/g, total flavonoids content of 26.48 mg QE/g, total tannin content of 6.23 mg TAE/g, water content of 8.38%, extract content in water of 31.96%, and sensory properties of yellow color and slight liked, bitter slightly taste and slight liked, and overall acceptance neutral.

Bambu Tali leaves are part of bamboo plants that have not been used optimally. Bambu Tali leaves can be used as a refreshing drink. The aims of this study is to determine the effect of blanching and drying temperature on the characteristics of the Bambu Tali leaves and to determine method of blanching and drying temperature which can produce the best characteristics of Bambu Tali tea leaves. This study used a Randomized Block Design with two factors. The first factor’s is the blanching method that is without blanching, steam blanching, and water blanching. The second factors that is drying temperature that consisting of 50oC, 60oC, and 70oC. Data were analyzed by analysis of variance and continued with Tukey test. The results showed that the blanching treatment and drying temperature significantly affected the water content, ash content, extract content in water, total phenolic, IC50, and organoleptic test. The steam blanching treatment with a drying temperature of 70oC is the best treatment to produce Tali’s bamboo tea leaves with a characteristics of water content is  5.17%, ash content is 5.52%, extract content in water is 35.70%, total phenolic is 36.92 mg GAE/g, and antioxidant activity of IC50 2,629.06 ppm, and color scoring of sensory evaluation is 3.55 (yellowish green to green), taste scoring is 3.55 (slightly astringent to astringent), Scent scoring of 3.45 (slightly leaf scent to leaf scent), and overall reception 4.90 (rather like).

<p>Traditional copra processing by smoking and sun drying methods will produce low quality copraand oil. In order to improve the quality of copra and oil, copra drier through oven system with controlled drying temperature is a necessity. The purpose of this research is to design a copra dryer through oven system that can be utilized by farmer groups. Research carried out from May 2014 to December 2015, with tool’s construction and field test conducted at the Repair Engineering and Laboratory Equipment of Indonesian Palm Crops Research Institute. Moreover, copra and oil’s quality analysis performed at Research and Standardization of Industrial Institute Laboratory, Manado. The quality analysis is based on valid quality standard. The research results showed that copra drier system on a farmers scale, using coconut coir as a fuel, has been built with capacity of 1550-1650 coconuts/process period. Drying temperature is varied between 28-70 Cwith optimum temperature at 55-60 C and drying time approximately 27 hours.It produces various copra such as, white copra, brown copra and dark copra, with water content of 4.36-4.88%, fat content of 63.53-64.17% and Free Fatty Acid of 0.05-0.12%. White copra, which then processed into frying oil, produced white color oil with water content of 0.05%, peroxide value 0.13 meq O2/kg without any lead (Pb) detected in the oil. As a result, coconut oil can be safely consumed without any purification process. In conclusion, copra drying through oven system is sufficient enough to apply for farmers group in order to encourage excellent quality copra and oil processing.</p><p><strong>ABSTRAK</strong></p><p>Pengolahan kopra secara tradisional dengan cara pengasapan dan penyinaran matahari  menghasilkan kopra dan minyak bermutu rendah.

Abstract-Sheet jam wasa modification of semi-solid topical jam made from fruits or vegetables, then concentrated with the aimedof forming solids or sheets. Jam generally usedripe fruit that was nottoo ripe and hada slightly sour taste. The purpose of this studyto determine the effect of starfruit and carrotporridge on the characteristics of sheet jam and to get a comparison of starfruit and carrot porridge on the characteristics of sheet jam. This study useda Completely Randomized Design (CRD) with 5 treatments, the comparisonedof starfruit porridgecarrotwere 0%: 100%, 25%: 75%, 50%: 50%, 75%: 25%, and 100%: 0% . Each treatment wasrepeated 3 times to obtain 15 experimental units. The parameterswereobservedin making sheet jam werewater content, vitamin C content, total dissolved solids (TPT), acidity (pH), degree of color, and organoleptic testing. The data obtained were analyzed with a variety of tests at the level of 1% and 5%. If the data obtained hada significant effect, then thedata would be continued withDNMRT (Duncan's New Multiple Range Test) at the 5% level. The researchresultsof starfruit and carrot porridge treatmentto the best sheet jams was 25%:75%with water content (36,53%), vitamin C (44,00 mg / 100 g of material), Total Dissolved Solids (42,20oBrix), pH (4,03), and degree of color (L=33,09, a=+9,31, b=+24,10 and0Hue=68,88).
