Abstract

Cauliflower is one of the vegetables that have the ability to adapt to coastal sandy land. Cauliflower production can be increased by extensification efforts using coastal sandy land. The research aimed to determine the type of liquid organic fertilizer, the fertilization interval of liquid organic fertilizer, and the appropriate dose of nitrogen fertilizer for the growth and productivity of cauliflower plant on coastal sandy land. The research was conducted in Jetis sandy beach, Banjarsari Village, Nusawungu Sub-district, Cilacap Regency. The study was conducted from August 2017 to November 2017. The experiment was arranged in a Factorial Randomized Complete Block Design (RCBD). Data were analyzed by F test followed by DMRT 5%. The results showed that (1) type of artificial liquid organic fertilizer gave best result on the dry root weight and chlorophyll b. (2) The 9-day-interval of liquid organic fertilizer application interval gave the best result on the fresh root weight and fresh plant weight, while the 4-day-interval of liquid organic fertilizer application gave the best result on dry flower weight. (3) The doses of N fertilizer significantly affected leaf area, root volume, fresh root weight, fresh leaf weight, dry leaf weight, fresh plant weight, dry plant weight, fresh stem weight, dry stick weight, fresh flower weight, flower weight dry, and flower diameter.

Abstract

Cooking oil is one of the basic human needs. Improving the quality of bulk cooking oil is necessary because it is related to economic reason. The bulk cooking oil have a lower price than brand package oil, of course. Based on these reasons, research is needed on the use of antioxidants to improve the quality of bulk cooking oil. This study aims to identify the phytochemicals of bay leaves extract through TOF profiling, analysis of iodine number and acid number of bay leaves extract against bulk cooking oil. TOF profiling was carried out to see whether bay leaves had chemical compounds that supported antioxidant activity which had an impact on the inhibition of fat oxidation. The research consisted of 4 stages: 1) extraction and fractionation of bay leaves, 2) TOF profiling of bay leaves extract, 3) application of bay leaves extract to bulk cooking oil, 4) analysis of iodine and acid numbers. Profiling TOF of the bay leaves extract showed 3 peaks : C6H13NO5 (cyclohexanol, galactose, and fructose derivatives), C11H14O5 (pyran and furan), andC11H19NO3 (morpholine derivate). According to SNI, the acid value maximum 0.6 mg KOH/g. Iodine value minimum is 45 g I2/ 100 mL (SNI 3741 : 2013). Based of this data standart, this study recommended use bay leaves extract in concentration 0.80%. The addition of bay leaves extract as much as 0.80% showed an iodine number of 48.2 g I2/100 mL and an acid number of 0.34 mg KOH/g where the positive control TBHQ showed an iodine number of 48.7 g I2/100 mL and an acid number of 0.19 mg KOH/g.

Abstract

Water is the basic needs of living things in this world. Infrastructure development that increased would cause the needs of water. Therefore, it has to be balanced with manage the good plan of water absorption region in an area. This research has been done in Kulon Progo districts that aimed at made maps and map the potential of water absorption region in Kulon Progo districts. The method used in this research was the tiered quantitative analysis survey with Geography Information System (SIG) software with the weighting parameter categorize model using overlap techniques in each parameter. The parameters were kind of rocks, rainfall, used land, and slope of the land. The data of the research was secondary data. Those were administration map, Topographical map, land used map, rainfall data, Shuttle Radar Topography Mission (SRTM), and soil map. The result of this research showed that water absorption region in Kulon Progo with dominated suitability condition in unsuitable class as wide as 32.804 ha followed by class as wide as 17.124 ha, and the smallest was class condition quite appropriate as wide as 7.976 ha.

Abstract

The demand for daily consumption of tomato fruit is increasing immensely. Nevertheless, the fruit is exposed to mechanical damage, shrinking, and softening as the maturity stages, handling, and storage are inappropriate, thereby affecting the texture. The study aimed to assess the texture profile, pectinase activity, and physicochemical parameters in tomato fruit at different maturity stages and storage temperatures. The fruits were harvested at 1-4 weeks after pollination and stored at a temperature of 16 ºC and 25ºC. There was an increase in the redness color (a*), TSS content, weight loss, respiration rate, and ethylene production, while the hardness, lightness color (L*), pH, and TA decreased with an increase in maturity stages at different storage temperatures. The higher Polygalacturonase (PG) and Pectin methylesterase (PME) enzyme activities were observed at 25 ºC compared to storage temperature of 16 ºC. It was confirmed that pectinase activity extremely affected the texture profile. For commercial purposes, it is suggested that tomatoes are harvested at 2nd and 3rd week after pollination for long distance transportation and at 4th week for fresh consumption and stored at a temperature of 16 °C.

Abstract

The application of biofilm biofertilizer is potential to improve soil fertility and increase plant yield. The research aimed to assess the use of organic fertilizer decomposed with biofilm biofertilizer to improve soil fertility and yield of upland kale in Vertisol. The field experiment was conducted in Vertisol at Jaten, Karanganyar, Central Java, arranged in a Randomized Complete Block Design with a single factor, which was organic fertilizer dose consisting of 0, 3, 6, 9, 12, 15, 18, and 21 ton.ha-1 organic with NPK fertilizer as comparison treatment. Upland kale seeds were planted in 15 x 15 cm plant spacing. The variables observed were total nitrogen, available P, exchangeable K, soil organic matter, pH, cation exchange capacity, leaf number, plant height, fresh and dry weight. The data obtained were analyzed using F test followed by Duncan Multiple Range Test (DMRT) 95%. The result showed that the organic fertilizer dose had a significant effect on all of the observed variables. Optimal doses of organic fertilizer to improve soil fertility and upland kale yield was 15 - 18 ton.ha-1. The highest yield of upland kale was observed in the treatment of 21 ton.ha-1 organic fertilizer (76.5 ton.ha-1), which was increased by 176% compared to control (34.7 ton.ha-1) and by 108.8% (45.78 ton.ha-1) compared to NPK treatments. The application of 3 ton.ha-1 organic fertilizer gave better yield of upland kale than NPK fertilizer.

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).
