Abstract

One of the reasons for the low eggplant production in Riau is that the soil type in Riau is generally Red Yellow Podzolik (PMK). Utilization of PMK soil as a medium for plant growth is faced with various problems, especially the physical, chemical and biological properties of the soil which are less supportive for growth. To be able to improve PMK soil, it is necessary to provide a lot of organic matter, such as vermicompost fertilizer. Vermicompost organic fertilizer is an organic fertilizer plus, because it contains macro and micro nutrients and growth hormones that are readily absorbed by plants. In addition, giving egg shells is a household waste that can still be used to fertilize plants. Eggshell contains 94% calcium carbonate, 1% calcium phosphate, 1% magnesium carbonate and 4% organic compounds (Rahmawati and Nisa, 2015). The high calcium carbonate contained in eggshells can be used as an alternative source of calcium. The purpose of this study was to determine the effect and the best combination of casting and chicken eggshell fertilizer on the growth and production of pondoh round eggplant (Solanum melongena L.). This research was carried out experimentally using a factorial Completely Randomized Design (CRD), which consisted of two factors, namely K (Kascing Fertilizer) consisting of 3 levels, and factor C (Chicken egg shells), consisting of 3 levels, each consisting of 3 repetitions, The number of experimental units is 27 plots, each plot consists of 4 plants and 2 plants as samples, so that the total plant is 27 x 4 = 108 plants. The result of this research is that the interaction of vermicompost fertilizer and chicken egg shells has a significant effect on plant height, stem diameter, number of fruits, fruit weight per plant, fruit diameter of eggplant plants, by giving 100 g of castor fertilizer/plant and 30 chicken egg shells. g/plant is the best dose in this study.

Abstract

Fish wealth in the Indonesian region is abundant and efforts are continuously being made to increase the catch. Abundant fish catches become leftover fish or discarded fish due to various reasons, for example the fishermen's limited knowledge and facilities in fish processing methods. It turns out that the remaining fish or discarded fish can still be used. Nowadays snakehead fish (Channa striata) is widely used to make fish sauce, but in the manufacturing process only the flesh is used, this causes the skin and bones to become unusable waste. In general, fish waste contains many nutrients, namely N (Nitrogen), P (Phosphorus) and K (Potassium), which are components of organic fertilizer.The increase in waste production greatly influences global warming which triggers climate change. With proper processing in accordance with the environment and its presence in the environment, it is hoped that the environment will be clean, healthy and comfortable, in addition, appropriate waste can produce use value that will add income. From the research results, it can be concluded that the addition of the bromelain enzyme with a concentration of 150 mL produces the highest nitrogen content, namely 0.39%, while for the phosphorus content, the addition of 150 mL of enzyme shows a higher value, namely 0.168% and the highest nitrogen content, namely 0.037%, is owned by POC with the addition of 150 mL of bromelain enzyme.

Abstract

This research aims to analyze differences in the organoleptic characteristics of coffee brewed using three methods, namely siphon, French press, and moka-pot. The practicum was carried out by brewing two types of coffee, namely Temanggung Palm Sugar robusta coffee (Coffee A) and Jambi coffee (Coffee B), using these three methods. Organoleptic test results show that there are significant variations in taste, aroma, color, clarity and aftertaste based on the brewing method. The siphon method tends to produce coffee with better clarity, while the moka-pot produces coffee with a deeper color. The conclusion shows that the brewing method influences the final characteristics of the coffee.

Abstract

Coffee is an agricultural commodity that is in great demand by the public. Coffee is a plant that belongs to the Rubiaceae family. The chemical composition is also influenced by the type of coffee, growing environment, and processing process. In Indonesia, robusta coffee (Coffea canephora) is widely cultivated. In this practicum, the parameters analyzed are organoleptic tests in the form of color, aroma, taste, clarity and after test using 3 types of brewing equipment, namely Shipon, French press and Moka-pot. The benefit of doing this practicum is that you can find out the organoleptic tests on the differences between brewing coffee A and coffee B using a siphon, French press and moka pot.

Abstract

Penicillin refers to a group of β-lactam antibiotics with high commercial value because it is precursor for semi synthetic antibiotics such as amoxicillin and ampicillin. It also has high antibacterial activity. Penicillin production in industrial scale uses large fermentation reactor which require optimum agitation. The present study was conducted to investigate the effect of agitation speed on penicillin production using Penicillium chrysogenum L112, which have high antibiotics activity against some bacteria. P. chrysogenum L112 which regenerated at 30°C for 7 days was suspended with distilled water. The suspension was inoculated to vegetation media to reach 2% (v/v) final concentration. It was then followed by activation at 28°C for 60 hours with 120 rpm agitation speed. The activated culture was inoculated to fermentation media to give 10% (v/v) final concentration in a 1 L fermenter at pH 7 and 28°C, aeration of 1 vvm, for 240 hours. Agitation speed was varied at 100, 150 and 200 rpm. Sample was collected every 24 hours and checked for its pH, dry cell weight, and antibiotics activity. The results of the present study indicate that agitation speed and time of incubation affected the P. chrysogenum ability to produce penicillin. The crude extract showed different effect when tested against different bacteria, which indicate different amount of penicillin produced. The best antibiotics activity was found at 150 rpm agitation speed, incubation time of 192 hours. The highest inhibition was found for Escherichia coli which showed 37 mm clear zone.
