Abstract

One obstacle that can limit the growth and production of rice is low water availability. Therefore, a comprehensive study of the response of rice plants to drought is very important. The study was conducted in the greenhouse of the Faculty of Animal Husbandry and Agriculture, Diponegoro University, from April to August 2016. The study used a 3 x 3 factorial design with 3 replications. The first factor is three types of rice (Sidenuk, Way Apo Buru, Pepe) and the second factor is water stress treatment (KA <field capacity = enough water, field capacity (KL), water saturation (JA). The observed parameters are protein content, leaf levels rolling (number of leaves rolled), relative water content (RWC), water use efficiency (WUE),  N, P, K uptake, rice protein content decreases with increasing water supply. The relative water content of rice plants decreases with increasing stress water that occurs in the limited water supply for the three types of rice Sidenuk rice has the lowest N seed content (2.1%) compared to Way Apo (3.0%) and Pepe (3.1%). The mineral content of P in both biomass and seeds is not really influenced by water stress, as well as K content of seeds.   REFERENCES Badan Pusat Statistik. 2018. https://www.bps.go.id/dynamictable/2019/04/15/1608/luas-panen-produksi-dan-produktivitas-padi-menurut-provinsi-2018.html Darwesh, R, S,S. 2013.

Abstract

To minimize the use of inorganic fertilizers is by giving rice straw compost to the soil. The rice straw compost is a potential organic material for lowland rice plants. This study was aimed to determine the effect of the combination of NPK fertilizer and rice straw compost on the growth and yield of IPB 3S rice variety. This research was carried out on farmers' land in Dowiwi village, Simpang Raya sub-district, Banggai district. The study used a factorial randomized block design with two factors. Factor A (NPK) consisting of four levels namely A1 (62.5 kg / ha), A2 (125 kg / ha), A3 (187.5 kg / ha) and A4 ( 250 kg / ha). Factor B of rice straw compost (B) consisting of four levels, namely B1 (1.25 tons / ha), B2 (2.5 tons / ha), B3 (3.75 tons / ha), and B4 (5 tons / Ha). The results showed that rice straw compost can be increased plant height and 1000 grains weight. The interaction of NPK and rice straw compost (NPK 62.5 kg/ha + 5 tons/ha) was able to minimize the use of NPK fertilizer by 75% in panicle length and 1000 grains weight.   REFERENCES Amrah ML.

Abstract

ABSTRACT This study was aimed to examine the effect of the substitution of compost leaves of sengon (Paraserianthes falcataria L.) on inorganic fertilizer on the growth and production of two varieties of soybean (Glycine max L.). The study was conducted on January to April 2019 at greenhouse, Laboratory of Ecology and Plant Production, Faculty of Animal and Agricultural Science, Diponegoro University. A completely randomized design (CRD) with 5 replications was used throughout the study. The first factor consisted of no compost and an inorganic fertilizer substitution, 25%, 50%, 75%, 100% compost substitution, respectively, and 100% of inorganic fertilizers. The second factor was two soybean varieties, namely detam 3 prida and malica. The parameters observed were number of branches, number of trifoliate leaves, number of pods, number of seeds, seed weight, the 100-seed weight. Data were analyzed using ANOVA and continued with the Duncan's Multiple Range Test at a significant level of 5%. The results showed that the dose of compost substitution affected the parameters of the number of branches, number of pods and number of seeds significantly. Soybean detam 3 prida varieties showed a significant effect on the number of branches and the 100-seed weight, while malika varieties showed a significant effect on the number of pods. Substitution dose of 75% compost (26.19 N/ha) showed the highest results on the parameters of the number of branches, number of pods, number of seeds, weight of seeds and the 100-seed weight, and resulted as the highest yield compared to no substitution on all plant parameters. On the basis of the data found throughout the experiment may be concluded that 75% compost of leaves sengon was the most suitable doses to be applied at the cultivation of soybean especially varieties of detam 3 prida and malica.

Abstract

Aren has an important role as a biofuel producer, so research is needed for the development of this plant. This research has been carried out in the Tissue Culture Laboratory of the Department of Agrotechnology, Faculty of Agriculture, Muhammadiyah University, North Sumatra, from October 2017 to September 2018. This study aims to obtain a combination of concentrations of growth regulators of curcumin and cytokines which are best for increasing plant population in vitro culture. , as well as to produce large quantities of quality plantlets in a relatively short time. Experiments in the form of a Completely Randomized Design (CRD) were repeated 3 times with 5 samples of each treatment to obtain 105 units of experimentation. The first series experiment was the regeneration stage, shoot tip results were cultured on WPM media with a concentration of 0.25 ppm + 1.0 ppm Kinetin which was used as explants. Furthermore, the shoots were regenerated in the WPM medium with the treatment of concentration of growth regulators of auxin and cytokinin which consisted of 7 treatment levels, namely (E0) 0.00 ppm NAA + 0.00 ppm BAP, (El) 0.00 ppm NAA + 0.25 ppm BAP, (E2) 0.50 ppm NAA + 0.00 ppm BAP, (E3) 0.50 ppm NAA + 0.50 ppm BAP, (E4) 0.00 ppm NAA + 0.75 ppm BAP, (E5) 0.50 ppm NAA + 0.75 ppm BAP, (E6) 1.00 ppm NAA + 1.00 ppm BAP. From the observed variables, the percentage of live explants and percentage of explants forming callus the best results were found in a combination of 1.00 ppm NAA + 1.00 ppm BAP (E6) concentration.   References Asikin D, Puspitaningtyas DM. 2000.

Abstract

Limited land owned by farmers which in the same land farmers grow 2 types of maize with different time, namely sweet corn and hybrid corn within 1 year. In the dry season farmers grow hybrid corn and in the rainy season farmers grow sweet corn. Farmers capital for purchase production facilities, especially for the purchase of seeds, fertilizers, and medicines whose prices are getting higher and higher, in addition to the price of corn and hybrid corn which always increases fluctuations, and in terms of cost and time of hybrid corn is higher than sweet corn. This will have an impact on income obtained by farmers. Sampling in this study was carried out by proportional random sampling. Determination of a large sample for the participation of smaller than 10000 can use the Slovin formula (Soekidjo, 2003) with the formula, to answer the objective, it can be used an analysis using total corn farming with total corn farming at one planting season, and to answer the purpose of both methods used using Gross Profit Margin. The results showed that the total income of hybrid maize and sweet corn in the research location was IDR.49.425.000 with an average income per respondent of IDR.852.155 / season and the average income per hectare was IDR. 1.433.855 / season. While the total income of sweet corn farming obtained by respondent farmers is IDR.55.383.000 with an average income per respondent is IDR. 1.065.057 / season and the average income per Ha is IDR. 3.018.147 / season. The percentage of gross profit margin shows that the percentage of sweet corn of 20.63% is received within 2 months and while hybrid corn is 23.20% received within 3 months.   REFERENCES   Andi B. 2016.

Abstract

AbstractCellulolytic degradation bacteria are microorganisms that are abundant in nature which can break down raw fibers of organic waste into compost. The purpose of this study was to obtain superior cellulolytic bacteria to degrade organic waste into compost and obtain permanent species and strain. The method used is DNA isolation by culturing bacteria with Luria Bertani (LB) media, quality and quantity analysis using DNA electrophoresis isolation technique visualized by electrophoresis technique followed by testing with Polymerase Chain Reaction (PCR) technique. Isolated DNA was amplified using a primer combination designed from the 16S rRNA gene sequence. The primary combinations used are 27F (5 '-AGAGTTTGATCMTGGCTCAG-3') and 1525R (5 '-AAGGAGGTGWTCC-ARCC-3'). Analysis of sequence data is compared with gene sequences that have been deposited into the public database in silico using the BLAST program conducted online on the NCBI website (National Center of Biotechnology Information). The results obtained by visualization of electrophoresis from isolation of DNA 6 isolates of cellulolytic bacteria M = λ DNA 50 ng / µl; 1 = KM25, 2 = SR75, 3 = JM, 4 = U6,5 = G8,6 = K13. DNA concentrations obtained from 6 isolates were quite high, ranging from 34.4 to 69.9 ng / µL. The results of the 6th PCR amplification were 6 isolates namely KM25, SR75, JM, G-8, KM13, AND U-6. In general, the six selected cellulolytic bacterial isolates belong to the genus Bacillus. Phylogenetic analysis using Boostrap 1000 x. The six selected bacterial isolates analyzed separated and formed two main clusters: the first cluster which included Bacillus thuringensis and Bacillus cereus and the Bacillus Subtilis cluster. The conclusion of the 6 isolates sequencing was KM13 (Bacillus thuringensis), G8 (Bacillus cereus), Sr75 (Bacillus cereus), JM (Bacillus subtilis), KM25 (Bacillus subtilis), U6 (Bacillus subtilis).   REFERENCES Afriani, A., Heviyanti, M. and syawal Harahap, F., 2019.

Abstract

ABSTRACT Rough flathead (Grammoplites scaber) is a non-economical and white-fleshed fish. It's suitable for fish-based processing products. Hanpen is one of the Japanese fish cake. Diversification of surimi-based Rough flathead becomes Hanpen. This research studied the consumer acceptance and chemical composition of Hanpen Rough flathead. The experimental methods are used in this research with 3 treatments and Deuteronomy, the addition of surimi Rough flathead A1 = 100 g, A2 = 150 g, and A3 = 200 g. The randomized block data, ANOVA, was performed to analyze the data. The results showed that Hanpen Rough flathead product that can be accepted by panelists is A2 treatment, which scores 7,28 at like level specification. The addition of surimi Rough flathead had a significant effect (p<0,05) on organoleptic test parameters (appearance, aroma, taste, and texture) and proximate tests (crude protein, crude fat, water content, ash content, and carbohydrate) to Hanpen. The highest value of proximate test for three treatments were crude protein = A1 (5,36); carbohydrate = A1 (11,36); crude fat = A2 (0,39); water content = A3 (83,67); dan ash content = A2 (2,84).   References Agustin, T.
