Abstract

Compost tea is a compost extract that has many nutrients. In addition, the planting medium is also important in plant cultivation. Cocopeat is very suitable for growing media because it can store nutrients and water. The purpose of this study was to determine the effect of giving compost tea induced by lignocellulolytic fungi on cocopeat media on the growth of kailan (Brassica oleracea L.) and to determine the type of compost tea and the best media composition on the growth of kailan plants. This research was conducted from May to July 2020 in the greenhouse of the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The research was conducted factorial using a completely randomized design (CRD) consisting of 2 factors, factor I was compost tea (A) with 2 levels of treatment, namely: compost tea aeration (A1) and compost tea nonaeration (A2). The second factor is the planting medium (B) with 3 levels of treatment ratio, namely: cocopeat and soil with a ratio of 2: 1 (B1); 1: 1 (B2); 1: 2 (B3) to obtain 6 treatment units. The control was not part of the treatment but the control was included in the graph as a comparison between treatments. The treatment was repeated 4 times. The parameters observed were plant height. The measurement data obtained were tested by the ANARA test. If there are differences in treatment, continue with the Tukey's test. The results showed that compost tea aerated (ACT) gave a higher average yield compared to compost tea noneration (NACT) while the composition of the planting medium for cocopeat: soil = 1: 2 gave a higher average yield than other media compositions.

Abstract

Compost tea is a source of additional nutrients that are easily utilized by plants along with water absorption so that it can improve plant growth. Apart from nutrients, the planting medium also plays an important role in supporting plant growth. Cocopeat is a good growing media composition because it can bind water and soil nutrients by forming storage pores so that the nutrients in the soil do not dissolve easily. The purpose of this study was to determine the effect of giving Compost tea induced by lignocellulolytic fungal inoculum on cocopeat growing media on the growth of red spinach (Amaranthus tricolor L.) and the effect of the interaction between compost tea and the ratio of cocopeat: the best soil to increase spinach plant growth. red. This research was carried out from May to July 2020 at the greenhouse of the Integrated Field Laboratory of the Faculty of Agriculture, University of Lampung.

Abstract

Alcohol is closely related to daily life. It is used as a solvent or additional substance in the food, industry, pharmacology, laboratory, and beauty sectors. Empty oil palm bunches waste is the potential to process into alcohol because it contains cellulose that can be transformed into sugar, and the sugar is fermented into alcohol. The objective of this research was to find out the reducing sugar and alcohol produced from empty oil palm bunches. This research was done in two stages. The first stage was the preparation of empty oil palm bunches with basal (NaOH) treatment. The second stage included fermentation with cellulose enzyme (Novozymes Yield CL) for 24 hours and then fermented with Saccharomyces cerevisiae for 72 hours. The substrate concentrations to use were 7.5% and 10% and starter concentrations were 10%, 15%, and 20%. Research data were analyzed by using a completely randomized design (CRD) and then followed with the least significant difference (LSD). The result showed that 7.5% substrate addition produced the highest reducing sugar by 3.014% and then 10% substrate produced 2.686% reducing sugar. The alcohol test result showed that 10% substrate and 20% starter were significantly different by 3.5%, and 7.5% and 10% produced the lowest alcohol by 1%.

Abstract

Shallots are mostly developed with tubers as planting material, even though they have many disadventages. An alternative that can be done is to use seeds in the form of botanical seeds (True Shallot Seed/TSS), but there is still a long nursery time. This study aims to obtain the concentration and soaking time of the gibberellin on the germination and growth of shallot seedlings. The research was conducted using a single factor experimental method that arranged in a completely randomized design. The treatments were 4 gibberellins concentrations i.e. 2, 4, 6 and 8 ppm which were immersed for 12 and 24 hours, with 3 replications and each replication consisted of 5 sample. The observed variables were germination, vigor index, height of plant, number of leaves, leaf area, fresh weight and dry weight of seedling. The results of the research showed that a gibberellin with a concentration of 2 ppm with soaking time of 24 hours was able to increase the germination and vigor index of shallot seeds, and as well as increase the growth of shallot seedlings.

Abstract

Pempek is one of the traditional snack food from Palembang which is made from fish and very popular in Indonesia. The objective of this study was to determine the effect of the combination of barred mackerel fish and pick handle barracuda fish meat on sensory, chemical, and physical properties and to determine the best economic formulation of pempek. This study used the Completely Randomized Design with six-level treatments of a combination of barred mackerel fish and pick handle barracuda fish, respectively, 200 g-0 g (P1), 160 g-40 g (P2), 120 g-80 g (P3), 80 g-120 g (P4), 40 g-160 g (P5), and 0 g-200 g (P6). The characteristics of pempek were observed on the sensory (color, aroma, taste, texture, and overall acceptance), chemical (moisture and protein content), and physical properties (hardness, cohesiveness, springiness). The result showed that the treatment only has a significant effect on the color parameter of sensory properties. The higher amount of use of pick handle barracuda fish significantly reduced the panelist preference on color. The best formulation chosen was the combination of 40 g barred mackerel fish and 160 g pick handle barracuda with an economic total raw material cost of Rp 12.750. This formulation is recommended to produce pempek with the best quality and economic cost.
