Abstract

Cattle manure contains high organic matter, so that this material is commonly used as plant nutrients in a form of organic fertilizer. In order to get a better understanding on the use of cow manure, the objectives of this research are (1) to determine the influence of liquid waste and solid livestock as fertilizer on soil quality and (2) to study the effect of both liquid and solid fertilizer on coffee plant growth. In this research, Completely Randomized Design (CRD) was employed as a research design, while data analysis was conducted using ANOVA. The F statistical test was applied to measure whether all independent variables could influence the dependent variable by using 5% and 1% (Alpha) degrees. The results showed that one time application of livestock wastewater improved C-organic chemical properties, N, P, CEC, Ca and Mg while soil chemical properties of pH, K, Na decreased. Two times application of livestock liquid fertilizer treatment improved soil chemical properties pH, N total, Ca, Mg and saturation bases. As for solid waste, one time treatment increased chemical properties of pH, C organic, N total, Ca and saturation of the base. The two times treatment could improve soil chemical properties of pH, N. total, P, Ca, Mg, base number and base saturation. Liquid waste fertilizer also found to provide significant effect on plant height and coffee plants quality. Additionally, (3) solid waste (compost) was found to have a significant effect on plant height, plant height rate and number of buds.

Abstract

Coffee leaf tea is made by drying coffee leaves in an oven at 70oC for 4 hours. The quality of coffee leaves tea does not only depend on the process of making tea but also the way the tea is brewed. There were 2 types of brewing techniques investigated in this study, namely infusion and decoction. Response Surface Methodology (RSM) was conducted to optimize the brewing time and temperature for obtaining highly functional coffee leaves tea with optimum total phenolic content (TPC) and antioxidant activity. The Rate-All-That-Apply (RATA) sensory technique was then applied to determine the sensory characteristics of coffee leaf tea. It was observed that optimum tea quality brewed by hot infusion technique was obtained at 80.03oC for 10.4 minutes while that of decoction technique was obtained at 95.38oC for 5.7 minutes. The coffee leaves tea brewed by decoction technique have higher total phenolic content, tannin and antioxidant activity than that of infusion technique (p-value<0.05). Even though the functional properties of coffee leaves tea such as total phenolic content and antioxidant activity,  tended to be lower than that of commercial black tea, the coffee leaves tea is still more superior than that of tea leaves that prepared as the process of coffee leaves tea. The coffee leaves tea that brewed by both decoction and infusion techniques were well accepted by consumer panel.

Abstract

Malang Regency produced 690,136 tons banana in 2016. The banana production is in line with the waste (banana stalks). Banana stalks contain 83.3% cellulose and 2.97% lignin, of which can be used as raw material for paperboard making. However, the banana leaf paper has a low tensile strength of 7.45 N/mm2, so additional fibers to strengthen the paper is necessary, such as coconut coir which has a tensile strength of 46.67 N/mm2. This research aimed to formulate the material for paper making, such as the fiber source (banana fronds and coconut coir), filler (tapioca), and water to produce paperboard with minimal costs. The research was conducted using a linear programming method with LINDO software. The formulation of a sheet of cardboard produced was 34.79 g of dry banana stalks, 19.20 g of coconut coir, 6.00 g of tapioca, 136.08 g of NaOH, 2080 mL of distilled water, and 1000 mL of water with manufacturing cost of IDR 6,931.15. The paper characteristics has gramature of 323.8 g/m2, moisture content of 19.75%, water absorption test of 743.2 g/m2, tensile resistance of 1.4 kN/m, and stiffness of 5.7 mN.m.

Abstract

Melon (Cucumis melo L.) cv. Gama Melon Parfum (GMP) is the new cultivar from cross-breeding of Natsuno Omoide (NO3) female parent and Miyamauri (MR5) male with phenotypic characteristics that is prominent such as very strong pleasant aroma when ripe. The physiological characteristics will be changed which have an impact on the formation of volatile compounds during fruit development. Therefore, the profile of strong volatile aroma compounds during fruit development to is critical to be identified. The volatile compounds analysis was performed on fruits harvested at 7, 14, 21, 28, and 35 days after pollination and storage at -20°C. Gas chromatography-mass spectrometry (GC-MS) was used for volatile identification. The results showed some volatile compounds changed during fruit development consisted of 8 esters, 2 alcohols, 1 acid, 3 terpenoids, and 3 hydrocarbons. The profile of volatile compounds was dominated by esters, followed by alcohols and acid respectively. Interestingly, the characteristics of the volatile compounds can differentiate between the ripe stage and unripe stage using principal component analysis. The findings of this study can be used to improve the quality aroma of GMP.

Abstract

Moisture diffusivity and activation energy are two important variables in a drying process to understand a certain product's drying behavior. This study aimed to determine the value of effective moisture diffusivity and the activation energy of red pepper in a conventional forced convective drying based on electricity (conventional convective drying/CCD) and forced convective drying based on solar energy (convective solar drying/CSD). The value of effective moisture diffusivity was determined using the equation, which refers to Fick’s second law. The Arrhenius equation determines the activation energy value as a model of the relationship of inverse temperature and the normal logarithmic value of effective moisture diffusivity. The results showed that the values of effective moisture diffusivity of CCD 70 °C were the highest. The regression analysis between the drying layers (X), and effective moisture diffusivity (Y) showed a polynomial pattern with a coefficient determination R2 value of 0.85 (CCD 70 °C), 0.81 (CCD 60 °C), 0.88 (CCD 50 °C), and 0.48 (CSD). (R2)  The higher moisture diffusivity values in CCD indicated that the drying systems are more stable than CSD. The drying activation energy calculation showed that the value of CCD's activation energy was 36.36 kJ/mol.K, while the value of CSD's activation energy was 31.28 kJ/mol.K. Those results were consistent with the results of the previous studies.

Abstract

Ultrasonication has been identified as a particularly promising technology for homogenization of dairy products. Homogenization of cream, by reducing fat globule size, can be utilized to inhibit creaming. The homogenization of cream usually leads to increased viscosity.  Cream with fat level greater than 17% cannot be homogenized with satisfactory results since conventional homogenization methods cause coalescence and mostly agglomeration. The aim of this study was to investigate the influence of ultrasonication on milk cream (5-30% fat) and to study the phenomenon of formation of fat clusters during sonication (0.5-15 mins) at low temperature (2°C). The results showed that ultrasonication can reduce the fat globule size, although it resulted in the formation of fat clusters at short time (<1min), but at longer time, fat clusters can be broken. On the other hand, ultrasound homogenization tends to increase the viscosity of cream at various fat contents. Microstructure of solid phase showed that there was formation of double emulsions and partial fat coalescence. Ultrasound homogenization with the addition of SDS as small-molecule surfactant can prevent the formation of fat clusters. Fatty acid composition in solid phase shows that it consists of long-chain fatty acids in higher amount compared to that present in the liquid fraction. Whereas the concentration of short and medium chain fatty acids in the liquid phase was higher compared to that in solid phase. The utilization and optimization of ultrasound for cream homogenization has a potency to solve the limitation of conventional method (pressure homogenizer) which commonly used in dairy industry.

Abstract

Mycotoxin is one of the food safety problems that raise concern because of its negative health impact and significant economic losses. Patulin is the most common mycotoxin found in fruits and its products like apple, orange, grape, pear, etc. There are 167 species reported to produce patulin; Penicillium expansum is the major patulin producer among those fungi species. Patulin is not classifiable as to its carcinogenicity to humans, but some studies showed the toxicities of patulin.  Patulin has a broad spectrum of toxicity such as acute toxicity, sub-acute toxicity, genotoxicity, embryotoxicity and teratogenicity, carcinogenicity, and immunotoxicity. There are several ways to detect mycotoxins, such as HPLC, TLC, ELISA, and PCR. The popular way to detect mycotoxin molecularly is PCR because of its sensitivity and specificity. To detect patulin molecularly require proper selection of target gene. Therefore, the biosynthesis of patulin, its influencing gene, and its underlying factor needs to be understood.
