Abstract

Bamboo shoots are saplings of bamboo that appear at the bottom of the soil, bamboo shoots are known to have very high water content and are usually consumed as processed vegetables such as stir-fry, stuffed spring rolls, curry, and pickles. One type of bamboo shoot that grows well in Bali is the tabah bamboo shoots (Gigantochloa nigrociliataBuse-Kurz). Seeing that the water content of bamboo shoots is very high, the shelf life and usability of bamboo shoots can be increased by turning them into semi-finished products in the form of flour. Bamboo shoot flour is oneof the foodstuffs that are dry and also easy to change components. In maintaining the quality of a food ingredient, packaging has a very important role. This research was conducted to determine the right type of packaging in maintaining the quality characteristics of bamboo shoot flour. This study uses a Completely Randomized Design which consists of two factors, the first factor is the type of packaging, namely (K1): polypropylene, (K2): aluminum foil, and (K3): paper sack. The second factor is storage time, namely (H1): 10 days, (H2): 20 days, (H3): 30 days. Parameters observed were water content, water absorption, bulk density, crude fiber, whiteness degree, and sensory test. The results showed that the paper sack packaging type treatment could better maintain the quality characteristics of tabah bamboo shoots flour during storage for 30 days with a water content value of 6.73 %, the water absorption capacity of 10.83 %, bulk density of 0.6445 g/ml, crude fiber. 27.16%, and whiteness degree of 49.47%. By using paper sack packaging, it will better maintain the quality characteristic of bamboo shoot flour during storage so that it does not get damaged quickly.

Abstract

The objetive of this research were to determine the self-life of loloh cemcem with and without grated young coconut pulp using Accelerated Shelf Life Testing (ASLT) with Arrhenius method. Loloh cemcem was stored in four storage temperaturs, namely 15oC, 35oC, 45oC, dan 55oC. The observed parameters were pH, and three sensory parameters using preference test, namely flavor, color, and aroma of the cemcem. The observations conducted until 50% of panelist refused loloh cemcem. The results showed the critical quality parameter of loloh cemcem with grated coconut was taste that followed zero order and without the same parameter was found for loloh cemcem without grated young coconut pulp but it followed first reaction order. The self-life of loloh cemcem with grated coconut and without grated coconut was 16.4 hours and 18.9 hours at room temperature or 280C. Comparison of shelf life prediction and determined by the manufacturer was different.

Abstract

The rice biomass potential of red rice (local varieties) such as rice straw and chicken manure can be utilized as a raw material for composting. This research aimed to determine the best composition ratio of compost raw materials and to find the minimum time to produce compost with such quality. This research used a treatment composition ratio of rice straw and chicken manure where P1 = (6 : 8), P2 = (6 : 7), P3 = (6 : 6), P4 = (6 : 5), and P5 = (6 : 4 ). The dimension of composting pile were 1 m length, 1 m height, and 1 m wide. Each treatment material assumed 50 kg. Piles of compost material in each treatment were covered using a tarp to keep the temperature and protect from outside interference during the composting process. The parameters measured were temperature, moisture content, yield, pH, nitrogen, carbon, and C/N ratio. The composting process lasted for 78 days with temperature ranged 30,1 – 51,1°C. Compost moisture ranged from 31,74 – 32,59%. Compost yield ranged 59 -64%, and pH ranged between 7,2 – 7,5. In general, the quality of the produced compost accordance to SNI 19-7030-2004 with a final C/N ratio was 16 - 33. The P1 which have composition ratio of rice straw and chicken manure 6 : 8 was the best treatment which have C/N ratio of 16 and for 63 days of composting process.

Abstract

The objectives of this research were to determine the shelf life of jackfruit pia use ASLT method (Accelerated Shelf Life Testing) based on critical moisture content model. Jackfruit pia was packed in two types of packaging, namely cellophane and LDPE packaging which were stored in three different storage humidity, such as 89,7%, 92,2% and 96,7%. Observation on each parameter was done every 2 days. Parameters were measured by organoleptic tests in some catagories such as visual parameters, color, aroma, texture, and flavor. Supporting parameters to determine the shelf life of jackfruit pia were initial moisture content (Ma) 0.12 g, critical moisture content (Mc) 0,15 g, packaging permeability (k/x) of cellophane 0,15gH2O/m2.day.mmHg and LDPE 0.09 gH2O/m2.day.mmHg, packaging area (A) of cellophane 0,015 m2 and LDPE was 0,021 m2, the weight of the samples per pack was (Ws) 25,71 g and ΔP was 2,66 mmHg. The calculation of ASLT method showed that the shelf life of jackfruit pia which stored at RH 75% which was packed with cellophane packaging was 129 days (4,3 months), in addition shelf life pia with LDPE packaging was 153 days (5,1 months).

Abstract

Chrysantemum cultivation in tropical region like Indonesia required the provision of additional light..The application of additional light is done by using artificial light from electric lamp in the evening for 4 hours after the sun set. This research determine the best cyclic pattern to generate the highest growth rate. The application that had been given in this research was the addition of LED lights of red-blue combination in a cyclic (off, on, off). Cyclic number given is 1 cycle, 2 cycles, 3 cycles, 4 cycles, 5 cycles and controls. The collected data were analyzed by regression analysis. The variables observed is plant height, the leaves number, the canopy area, and the rod diameter. The result showed that the addition of LED lights of red-blue combination for one cycle gave the best impact for rate of growth of chrysanthemum plant. The addition of LED red-blue combination one cycle gave the best effect against chrysanthemum plant growth, which was showed produced the highest growth rate of plant height (y = 1.106x + 2.11), the leaves number (y = 0.514x + 3.163), the canopy area (y = 2.346x + 21.61), and the rod diameter ((y = 0.082x + 0.168).

Abstract

The purpose of this study was to determine the shelf life of Jaje Gambir are packed with packaging made of woven bamboo-based. The study also aimed to design or designing packaging for Jaje Gambir, which serve as the base material is a woven bamboo. The experiment was conducted using a completely randomized design (CRD). In this study, the packaging has been created and woven into shape at the time of trial run given that treatment with the coating, plating treatment is performed is coated with plastic wrap. This type of treatment given in this study there are four kinds, namely, P1 (without coating), P2 (inner packaging plastic coated, outer uncoated), P3 (inner packaging is not coated with plastic, outer plastic coated) and P4 ( packaging plastic coated on the outside and inside). This study in addition to determine the shelf life of Jaje Gambir also to determine public perceptions of packaging designs that have been made, to test it conducted a survey and assessment of the public perception of the packaging design is created. The results showed a shelf life of Jaje Gambir is for 2 weeks, the product is still in a decent state only until the second week. In the next week the quality and the quality of products has decreased and is not suitable for consumption, the texture of the product has become harder and discoloration of Jaje Gambir become yellowish due to the emergence of the fungus on Jaje Gambir. The results of the public perception survey showed the average people agree with the statement contained in the questionnaire and likes to design packaging made of woven bamboo.
