Abstract

A research  to study the sterilization   method  and application   of Kinetin  and IAA to induce the Durian  young  leaf (Durio zibethinus) in MS  medium   was conducted in Balai Benih Induk Hortikultura in Salaman  Magelang  district  of Central  Java  started  on September  until December 2003. The Laboratory experiment   was arranged  in two phases,  which were  the optimation  phase of sterilization   and  induction   phase.  At  the  first  phase,  the  sterilization method  used  was  the modification   of Mulya  (2001) method.  The modification   use of sterilant,  vitamin  C antioxidant, Alcohol  70 %, Benlate, Agrept,  Tween-20  and Betadine  were done to obtain  effectiveness   of the sterilization.  Explants  planted  then in MS medium  for two weeks. Contamination   time, percentage of contamination   and viabilitas  (percentage of living explants)  were observed  then.  At the second phase,  the treatments were arranged  in a 3 x 3 factorial  completely   randomized   design  (CRD)  to observed  the influence  of Kinetin  and IAA combination.   The concentration   of Kinetin  observed were 2, 4, and 6 mg/I, where  as the IAA concentration   were 0.5,  1.0, and  1.5 mg/I. All treatments were  repeated  three  times,  with three samples  on each  replication.   The percentage   of browning explants, percentage  of contaminated   explants,  site of  contamination   and percentage of explants live were observed  at the end of incubation. The results  showed that sterilization  of Durian young leaves explants  with 1  g/l deterjent  for 15 minutes  then by 2 g/l Benlate  and Agrept  for 10 minutes,  then by 1  g/200 mg Vitamin C, then by Alcohol  70 % for 1  minute, then by 20% Clorox,  then by 2 drip of Tween-20  for 10 minute and then by Betadine  decreased  the contamination down to 50 %, and this kind of sterilization  was relatively better than  the other  kinds.  Application   of growth  regulators   were  not  able  to induce  explants growth,  but stimulated  callus formation  at the cutting surface though,  in the application  of Kinetin 4 mg/1 + IAA 0,5 mg/I, Kinetin 4 mg/1 + IAA  1,5 mg/1, Kinetin  6 mg/I+  IAA 0,5  mg/1 and Kinetin 6 mg/l+IAA   1,0 mg/I.

Abstract

Potassium is one of important soil nutrients. The content of potassium in the jatropha rind compost is quite high reaching 11.36%. The high content of potassium in the jatropha rind has potential to increase the productivity and fulfill the needs of soil nutrients in the cultivation process. The research aims to study the influence of jatropha rind compost as substitute KCl fertilizer on sweet corn (Zea mays saccharata Sturt.), and get the proper rate of the compost for increasing the growth and yield of sweet corn. This research was conducted using an experimental method with a single factor that was arranged in a completely randomized design. Treatments were combination of jatropha rind compost and KCl rate, consisting of four levels, 250 kg KCl/hectare + 0 KJP kg/hectare, 125 kg KCl/hectare + KJP 273.89 kg/hectare, 62.5 kg KCl/hectare + KJP 410.84 kg/hectare, 0 kg KCl/hectare + KJP 547.79 kg/hectare. Each treatment was replicated 3 times so that there were 12 experimental units and each unit consisting of three plants trial so that there were 36 plants. Each plot of the experimental unit was fertilized using manure 20 ton/hectare, urea 400 kg/hectare which was applied 2 times and SP-36 300 kg/hectare. Results indicate that the treatment of mix dose of compost rind jatropha and KCl does not affect significantly on growth and yield of sweet corn. Sweet corn plants fertilized with jatropha rind compost with the dose of 547.79 kg/ha had the same growth and yield those of 250 kg/ha KCl. The study concluded that jatropha rind compost can replace KCl fertilizer.

Abstract

Cassava has been known to have low glycaemic index (GI) recommended for diabetics. Cassava can be used as alternative food source for substitution of rice as Indonesian staple food. The current study aimed to investigate phisycal and chemical properties of food diversification of cassava. Levels of dietary fibre were measured by enzymatic-gravimetric AOAC, while total sugar content was measured by Lane-Eynon titration. Determination of starch was observed by using spectrophotometer and energy analysis by bomb calorimetry. Level of glycaemic index (GI) was  determined by EL, S.N. method. The sensory analysis was performed by preference test by using hedonic scale towards 20 panelists. Analysis of cost and benefit was used to investigate the economic feasibility of the products. Among several products of cassava, analog rice has the highest value of dietary fibre (4.72%), starch (75.64%) and energy level (349.38 cal/kg).  In addition, it has the lowest value of total sugar content (1,19%) and GI (56).  It is also the most preferable in terms of colour (4.35), aroma (3.90), taste (4.35) and general acceptance (4.05). Economically, analog rice provides the highest profit than instant tiwul and oyek, which are 1.66; 1.56 and 1.47 respectively.

Abstract

Fruit flies (Bactrocera sp.) are the most common types of plant pests attacking fruit plants. The pest attacks the fruit in the plantation. The control of fruit flies is quite difficult, which is usually done by using eugenol. Fruit flies are insects that are sensitive to light with wavelengths of 300-650 nm. The light trap is a method commonly used yet it is rarely used to control the fruit flies. This research was conducted to determine the effect of the color variation in light traps on the number of trapped fruit flies. This study used quasi-experimental research methods. The data were analyzed descriptively and continued with one-way ANOVA statistical testing using SPSS 25.0. The results showed that the highest average number of fruit flies was in light traps with the addition of blue lights of 17.22. Post hoc tests showed that blue lights were more effective in attracting flies into light traps.

Abstract

Increasingly healthy lifestyles and advances in technology make people tend to prefer consuming fresh-cut fruits. Modified Atmosphere Packaging (MAP) contributes to extending shelf life and improving postharvest product quality. This study was aimed to determine the effects of argon-based MAP combined with heat treatment on the quality of the fresh-cut cavendish. There were four treatments examined, consisting of the combination of MAP with 73.70 % argon gas and heat treatment at 40 °C for 5 minutes (P1), heat treatment at 40 °C for five minutes (P2), MAP with 73.70 % argon gas (P3), and without treatment (P4). Each treatment consisted of three replications, and all experimental units were stored in a storage area at a temperature of 10 °C. The variables of fruit hardness, total titratable acidity, reducing sugar content, and total phenolic compounds were observed at 0, 2, 4, 6, 8, and 10 days of storage. The results of the study showed that MAP and heat treatment could maintain freshness and slow down the degradation of fresh-cut cavendish quality. The combination of MAP treatment with 73.70 % argon gas and heat treatment at 40 °C for five minutes can slow down the degradation of fresh-cut cavendish quality and suppress the total titratable acidity formation until the end of the storage period (ten days).
