Abstract

Tabahbamboo shoots are young shoots of bamboo that grow from the base of a bamboo clump which has a lot of nutrition so that it requires continuous treatment to maintain the quality. One effort that can be done is to use the concentration of CaCl2and temperature. The use of concentration CaCl2has many benefits, of which it is easy to apply and can prevent food collation from becoming soft as a result of the processing and heating effect. The research was carried out to determine the CaCl2concentrations and the correct drying temperature of tabah bamboo shoots flour. The study used a completely randomized design (CRD) which consisted of two factors, the first factor used in the research design is a CaCl2concentration of worms and the second factor used is drying temperature. The first factor consists of four levels, CaCl2concentrations 0%, CaCl2concentrations 2%, CaCl2concentrations 4%, CaCl2concentrations 6%. The second factor is three degrees, drying temperature 60°C, 70°C, and 80°C. The parameter observed in the study consist of yield, water level, ash content, protein levels, rough fibers, colors, and organoleptic test consisting of the color, aroma, texture, and overall acceptance of the hedonic test. The best treatment combination is a CaCl26% and drying temperature 80°C, which result in water 10,70%, ashes level 24,23%, protein level 24,38%, roughly fiber 18,13%, aroma 2,90, color L 86,85 and b 8,15.

Abstract

Paprika is one type of vegetable horticulture plant. Based on the results of the preliminary study conducted, the price per kg of paprika in the traditional market is Rp25,000, while for the modern market the price per kg of paprika is Rp65,190. The price of paprika in the modern market is higher than the price in the traditional market because of the additional treatment given. This study aims to determine the additional treatment given to paprika in traditional markets and to determine the profit marginof handling paprika in traditional markets. This research uses descriptive quantitative research methods. This research was conducted in one of the traditional markets of Candikuning, Tabanan Regency and the modern market of Tiara Dewata Denpasar. The results showed that the traditional market did not give additional treatment to the peppers before being sold, in contrast to the modern market Tiara Dewata which gave additional treatment before the pepper was sold. Additional treatment is to package chili using plastic wrap. The results of this study also show the profit margins of the two markets, namely the profit margin obtained by the traditional market of 2.93% while the profit margin of the modern market is 27%. From the assumption of traditional market profit margin calculation, only the addition of paprika packaging with plastic wrap gives an increase in the profit margin of 18.35%.

Abstract

Household waste can be processed into compost. The purpose of this research is to obtain a good mix composition between household waste and rice hulls that produce compost quality according to SNI and determine which biocomposter produces the fastest compost. In order to produce compost, the household waste was added with rice hulls to determine the best material compositionratio and to achieve Indonesian standar in compost material i.e SNI 19-7030-2004. The comparison between household waste and rice hulls for A1, A2, and A3 is (1:0), (1:1) and (1:2) respectively. The composting process was carried out for 60 days and used two different biocomposter models, namely modified biocomposter and old biocomposter. Temperature, pH and water content were measured daily while organic matter, electrical conductivity (EC) and C/N ratio were measured at the beginning of composting and at the end of composting. The results showed that the final temperature and final pH in all bio composters did not show a significant difference. For the best water content produced by treatment A1 (1:0) on each bio composter. The best composition of the mixture produced in the ratio A1 (1:0) because the household waste obtained or the initial raw materialhas met the C/N ratio of compost raw materials, which is 45.81. All biocomposters have the ability ofproducing compost within 60 days. All bio composters reached a thermophilic temperature on day 25 andall bio composters run into a decrease in temperature on day 45, due to the addition of water every 7 daysduring the composting process.

Abstract

Modification of a simple biocomposter basket was carried out because there were still shortcomings i.e. the support poles were not strong enough to support the net, the net used was not sturdy, the net hole was too large and there was no seat base. The purpose of this study was to modify the previously designed biocomposter basket, to test the performance of a simple household-scale biocomposter basket. The research was carried out in two stages, namely the stage of modifying the frame with the addition of support poles, the base of the seat at the bottom, then replacing the net. The second stage is a performance test with composting carried out for 60 days. Household organic waste and rice hull as raw materials were treated with: A1 (1: 0), A2 (1: 1), and 3 (1: 2). The frame construction is declared safe because it can support a compost load of 32 kg with tensile stress (σ) of the frame, which is 0.275 N/mm2 which is smaller than the allowable stress (σ) of the material, which is 48.1 N/mm2. The result of the modification is to strengthen the frame by adding 4 support poles, replacing the net with a size of 0.5 mm, and adding a seat base measuring 10 cm from the ground. Based on the results of the performance of the modified biocomposter basket, it shows that the 6 baskets have the same performance, for the best compost composition is produced at a ratio of A1 (household waste without mixture) because the raw materials for household waste have met the requirements of the C/N ratio from the beginning to the end of composting

Abstract

Light is the main energy source for plants for the photosynthesis process. In indoor cultivation systems (plant factories), LEDs can be used as artificial light. The dominant light colors absorbed by plants for the photosynthesis process are red and blue, but the proportion of the LED colors used is unknown, so it is necessary to research the proportions of light colors. This study aims to determine the effect of the proportions of red, blue, and white light on the chlorophyll content (SPAD value) and the canopy area of Pakcoy. Pakcoy was planted in a growth chamber and given seven different proportions of light for 12 hours with a lamp total of 60 Watt and light intensity of 2000 lux. This study was conducted for 49 days, and the observations to make once aweek. The results showed the proportion of red, blue, and white LED light treatment affects the chlorophyll content and canopy area. The proportions of LED light 30 Watt red, 20 Watt blue, and 10 Wattwhite produced the highest chlorophyll content (35.0 SPAD value) and canopy area (70.7 cm2). In conclusion, the proportion of red, blue, and white LED light showed significantly different in the growth of Pakcoy.

Abstract

Increasing the yield of oyster mushrooms plays an important role to meet market demand and is expected to improve the welfare of farmers. This research was conducted to see the effect of the concentration of EM4 addition on the fermentation of the growing media as well as the control of environmental temperature and humidity on the physical characteristics of oyster mushrooms, and also the best interaction between the two treatments. The study used a factorial randomized block design with two treatment factors, namely the addition of EM4 (without EM4, 2, 4, 6, 8, and 10 mL/baglog) and temperature and humidity control (conventional and automatic controlled environment). Each treatment was made three times replication. The results showed that the addition of EM4 treatment and control of temperature and humidity had a significant effect on fresh fruit body weight and stalk length. The interaction of the addition of EM4 treatment and control of temperature and humidity significantly affected stalk length but did not affect the parameters of fresh fruit body weight, number of fruit bodies, hood diameter, and age of the first harvest. The addition of EM4 4 ml/baglog and controlled environment automatically is an interaction treatment that produces the best physical characteristics of oyster mushrooms. The physical characteristics produced were 125.8 g fresh fruit body weight, 21 fruit bodies, 6.92 cm hood diameter, 7.5 cm stalk length, and 24 days of the first harvest.
