ABSTRAK Bambu tabah termasuk kingdom Plantae, divisi Magnoliophyta, kelas Monocotyledoneae, ordo Graminales, famili Gramineae, sub famili Bambusoideae genus Gigantochloa, spesies Gigantochloa nigrociliata Buse-Kurz. Bambu tabah merupakan varietas asli yang berasal dari Pupuan-Tabanan dan banyak dibudidayakan di desa Payangan Gianyar. Penelitian ini dilakukan degan tujuan untuk menentukan kemasan yang dapat mempertahankan karakteristik yang terdapat pada teh daun bambu tabah dengan perlakuan pengemasan menggunakan tiga jenis kemasan yang berbeda yang disimpan pada inkubator dengan suhu 30 °C ± 3 dengan lama penyimpanan enam minggu. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari dua faktor yaitu penggunaan jenis kemasan yang berbeda dan lama waktu penyimpanan. Faktor pertama terdiri dari tiga taraf yaitu, (K1) : Alumunium Foil, (K2) : Plastik Polipropilen (PP), dan (K3) : Paper Sack. Faktor kedua terdiri dari tiga taraf yaitu, (T1) : 14 hari penyimpanan, (T2) : 28 hari penyimpanan, dan (T3) : 42 hari penyimpanan. Parameter yang diamati dalam penelitian terdiri dari Kadar Air, Laju Pengeringan, pH, Total Asam, Total Fenol, Total Flavonoid, dan Uji Organoleptik terdiri dari warna, aroma, dan rasa pada daun teh bambu tabah yang diseduh. Hasil penelitian menunjukkan bahwa kandungan fenol tertinggi terdapat pada perlakuan penggunaan jenis kemasan alumunium foil selama penyimpanan 42 hari yaitu 119.354 mg/100g dan total flavonoid yang tertinggi atau terbaik terdapat pada perlakuan penggunaan jenis kemasan alumunium foil selama penyimpanan 42 hari yaitu 27.419 mg/100g.  ABSTRACT Rigid bamboos include kingdom Plantae, division Magnoliophyta, class Monocotyledoneae, order Graminales, family Gramineae, sub family Bambusoideae genus Gigantochloa, species Gigantochloa nigrociliata Buse-Kurz Tabah bamboo is a native variety originating from Pupuan-Tabanan and is widely cultivated in Payangan Gianyar village. This research was conducted with the aim of determining the packaging that can maintain the characteristics contained in tabah bamboo leaf tea with packaging treatment using three different types of packaging stored in an incubator at a temperature of 30 ° C ± 3 with a storage time of six weeks. This study used a completely randomized design (CRD) which consisted of two factors, namely the use of different types of packaging and storage time.

Sale raja banana are foods processed by mature banana which have been through thedrying process. During storage, quality of sale raja banana decreased in terms of chemicalcomposition and organoleptics. It is needed a method to maintain the quality of sale rajabanana during storage by applying packaging technology. The purpose of this study was todetermine the effect of packaging methods (without packaging, HDPE packaging and HDPEvacuum packaging) and storage time on the chemical composition and organoleptic quality ofsale raja banana. The design of this study consisted of two factors: packaging using threetreatment levels (without packaging, HDPE packaging, and HDPE vacuum packaging) andstorage time with five levels of treatment (0, 7, 14, 21, and 28 days). Data was processed usingfactorial Completely Randomized Design (CRD) with three replications. The chemicalparameters analyzed were water content, ash content, reducing sugar, pH, and organoleptictests (including color, aroma, taste and texture). The results showed that the storage of saleraja banana with HDPE vacuum packaging for 28 days gave the best results for all parameters

This research is about effectivity analysis of two kinds of fungi i.e. Beauveria bassiana and Metharrizium anisopliae as Aedes aegyptilarvacide, it has been conducted at laboratories Zoology in Biology Department, Mathematics and Natural Sciences Faculty, Syiah KualaUniversity. Aims of this research were estimating maximum time storage of fungi powder as effective larvacide and the number of bacteriacolonies were found in water used for experiment. This research was used Completely Randomized Design (CRD). The experiments consistof two factors i.e kind and saving time of fungi. The result show that the longer the storage time of Beauveria bassiana the more ineffectiveit was as larvacide and the least fungi colonies were found. Metharrizium anisopliae on the other hand, the longer it was kept, the moreeffective it was as larvacide and the more fungi colonies were found.

Duck meat is a perishable food that has a short shelf-life. Therefore, packaging is needed to be used tomaintain duck meat quality during storage, one of the ways to extend shelf-life of duck meat is usingpropolis extract as edible coating which is contained antioxidant substances which can be used to extendduring storage. The aim of this research was to analyze the effect of propolis extract as an edible coatingmaterial on duck meat to maintain the quality and extend shelf-life of duck meat at room temperature.The research was used a completely randomized design (CRD) factorial 4x3 with 3 replications,consisting of 4 propolis concentrations (0.0%, 0.5%, 1.0%, 1.5%) and 3 storage times (0 hours, 6 hoursand 24 hours). Duck meats coated with propolis extracts had a significant effect on the water content andantioxidant activity of duck meat (P < 0.05). The storage time had a significant effect on the pH valueand the cooking loss of duck meat (P <0.05). The addition of propolis extract and storage time had asignificant effect on the pH value, cooking loss and antioxidant activity of duck meat (P <0.05).

Black garlic is a garlic that experiences warming at a certain temperature and time to find higher antioxidant activity. This research aimed to know effect of antioxidant content’s stability of extract BG to pH and temperature. The experimental design used in this research was a completely randomized design with replication, which consisted of two factors. The first factor was pH (4, 6 and 8). The second factor was temperature (30, 50 and 70ºC). Data were analyzed with analysis of variance, followed by Duncan test. The results showed that pH and processing temperature very influential to antioxidant activity, total phenolic and total flavonoid. The results showed that the best treatment was pH 4 and temperature 30ºC which the best resulted antioxidant activity, total phenolic and total flavonoid that stablest. The resulted of antioxidant activity, stability of total phenolic and total flavonoid that were 75,13%, 42,47% and 77,71%. The treatment of pH and processing temperature change compounds of extract black garlic. Myricetin and quercetin appeared on treatment pH 4 with temperature 30ºC and pH 8 with temperature 70 ºC. The treatment of pH and processing temperature of black garlic extract reduced antioxidant activity, total phenol and total flavonoid. pH and temperature form new compounds.

The use of formalin increasingly widely circulated among sellers tahu, because nature tahu easily broken then the sellers know much use out using formalin. Turmeric has active compounds that issaponin. It can be used to minimize the presence of formaldehyde in tahu This study used tahu immersed in 5% formalin solution added a solution of turmeric. The research carried on in the Laboratory of the Polytechnic Palembang Health Nutrition Department. Determination of formaldehyde using a spectrophotometer test. The study used a completely randomized design (CRD) with a model of Factorial three factors, namely soaking treatment (60 minutes, 75 minutes, 90 minutes) giving a solution of Turmeric (0 %, 10 %, 15 %, 20 %) and storage factor (0, 24, 48, 72 hours). The parameters used are formaldehyde levels and organoleptic test. These results indicate that treatment of soaking time did not significantly affect the levels of formaldehyde in tahu that F count -0.022 smaller than F table 6.94. Treatment addition of turmeric solution concentration does not significantly affect the levels of formaldehyde at 0.864 tahu that F count is smaller than F table 3.16. The storage time treatment also did not significantly affect the levels of formaldehyde in tahu that F count -11.16 smaller than 2.73. However, the interaction between the immersion treatment, turmeric solution concentration and storage time significantly affect the levels of formaldehyde in the tahu, namely 282.16 F count larger than F table 1.75. And the results of organoleptic able to change the texture of aroma and color in tahu with decreasing levels of formaldehyde in tahu. In this study, formaldehyde levels lowest in 90 minutes soaking treatment, the concentration of 20 % deposit 72 hours .
