Abstract

Efforts to overcome R. solanacearum which causes bacterial wilt (BW) in ginger in peatlands are through a strategy to suppress the initial population. One of the efforts is to use endophytic fungi (CE) as biological control agents. This study aims to examine the use of several endophytic fungi isolates from pepper to suppress bacterial wilt disease and improve the growth of ginger. The treatment of CE biological agents in the form of Aspergillus spp., Fusarium sp., T. harzianum, and T. viride to suppress wilt disease in vivo and the use of biological agents as biofertilizers in the field. The source of the pathogenic bacterium P. solanacearum was obtained from samples of wilted rhizomes from community ginger field isolated on NA media. This study was arranged based on a completely randomized design with five replications. The research variables were wilt disease severity, plant height, number of leaves, number of stems, stem diameter & rhizome weight. The results showed that R. solanacearum caused symptoms after an incubation period of 9 days after inoculation. The four CE isolates were able to suppress the symptoms of ginger wilt in the range of 70-80%. The use of CE isolate was also able to improve the growth of ginger, but it has not been followed by an increase in the production of ginger rhizomes. It is suggested that the use of CE as a biofertilizer needs to be increased in the frequency of its application.

Abstract

Red onion (Allium ascalonicum L.) is a spice plant whose needs as a kitchen spice continue to increase. Some of the obstacles faced in meeting community needs include the availability of inorganic fertilizer needs and seed preparation before planting. From this fact, it is necessary to cultivate through the use of organic fertilizers by cutting bulbs on shallot seeds before planting, so that it is expected to obtain the expected results. The study was conducted from May to July 2021. Field experiments were carried out using the split plot design method, as the main plot. Cutting tubers (P): P0 tubers that were not cut, P1 cutting in parts, P2 cutting in parts and subplots, namely the dose of organic chicken manure (D) D0 control, D1 15 tons/ha, D2 20 tons/ha. Plant variables include plant length (cm), number of leaves (strands). number of tubers per clump (tubers), number of tubers per plot (tubers), fresh weight of tubers per clump (g), fresh weight of tubers per plot (kg). The results showed that by giving a dose of chicken manure 20 tons/ha by cutting onion bulbs, the highest yield was 1.64 kg/plot or equivalent to 4.47 tons/ha

Abstract

The corn plant is one of the most important food crops other than rice and soybeans. Besides being consumed as direct food and animal feed, it is also used as raw material for other industries, such as alternative fuels, polymers, corn oil and others. This study aims to determine maize varieties that have high growth potential and yields in Bireuen District. This research was conducted from September 2020 to January 2021 in the village of Cot Kruet Makmur Subdistri, Bireuen District, Aceh Province. This study used a randomized completely block design (RCBD) consisting of 7 varietas of corn plant, namely the Bonanza variety, Royal 76 variety, Talenta Variety, Ganebo variety, Sweet Boy variety, Paragon variety, Jambore variety. The observed parameters consist of a growth component and a yield component. Growth components include: plant height, number of leaves, stem diameter, and 50% flowering age. While the yield components included: weight of corn cob, length of corn with cob, number of seeds per cob, weight of cob seeds, weight of 1000 grains, and yield per hectare. The result showed that the adaptation test of several varieties of corn plant had a different effect on each observation. Jambore variety is one of the varieties tested for its adaptation in this study, this variety has great potential to be developed in Bireuen district, because the Jambore variety is able to produce the most cobbled cob result among other varieties, weighing is about 22,84 ton ha-1.

Abstract

Glutinous corn or pulut (Zea mays Ceratina) is a type of corn that is currently in demand by the public. The productivity of glutinous corn is low because corn planting is generally carried out on Ultisol type soils with acidic characteristics and poor in nutrients. This study aims to determine the effect of the application of biochar and inorganic fertilizers (urea, SP 36 and KCl on the yield and yield components of glutinous corn plants. The test method was carried out by factorial RAK with two factors. The first factor was the dose of rice husk biochar (0, 5, 10). and 15 ton ha-1) and the second factor is a combination of inorganic fertilizers (Urea, SP 36 and KCl). The treatment dose of biochar is 10 tons ha-1 and acombination of fertilizers 200 kg ha-1 Urea + 75 kg ha-1 SP-36 + 75 kg ha-1 KCl gave the best yield on plant height, number of leaves, length of cob, weight of cob per plant, weight of cob per plot.

Abstract

Asam pedas is a soupy food with spices and the main ingredient is thick-fleshed river fish. This food has a low shelf-life, so it is necessary to apply sterilization technology. This research uses catfish as the main ingredient and retort pouch as packaging. This study aimed to determine the best sterilization time for catfish’s asam pedas using retort pouch packaging based on physicochemical and microbiological characteristics. The sterilization time used is 5, 10, 15, 20, and 25 minutes. Parameters observed were fat, protein, pH, thiobarbituric acid (TBA), texture, and Total Plate Count (TPC). The results showed that the sterilization time did not affect fat content, protein content, hardness level, TBA value, and the number of microbes, but the sterilization time significantly affected the pH value of catfish’s asam pedas packaged in retort pouches. Overall, the sterilization process carried out in this study did not change the physicochemical and microbyological characteristics of the catfish’s asam pedas. The best treatment in this study was a sterilization time of 25 minutes with a TPC value of 6.14 x 106 CFU/ml, the protein content of 11.89%, the hardness level of 178.81 gf, the pH value of 6.11, the fat content of 6.27%, and the TBA content of 0.19 mg malonaldehyde/kg.

Abstract

The jajar legowo planting system needs to be implemented in all regencies/cities in North Sumatra, because this planting system is an attempt to optimized agricultural yields. This study purposes were: 1) determined the farmers’ attitude to implement the jajar legowo system; 2) determined the factors that influence the implementation of jajar legowo system at the research site; and 3) determined how farmers implemented the jajar legowo planting system at the research site. The method used to determine the research location applies purposive sampling. The method of determining the sample used is "Stratified Random Sampling" based on the area of land cultivated by farmers. The analytical method to determine the factors that influenced the farmers’ attitude to implement the jajar legowo system used a Liker scale, while the analytical method determined the factors that influenced the implementation of the jajar legowo system used multiple linear regression. The research results can be concluded that 1) the farmers’ positive attitudes towards the jajar legowo system were 16 people (53.33%), and negative attitudes were 14 people (46.67%). The positive attitude was shown by the farmers being satisfied with the jajar legowo system. 2) Simultaneously, the factors of physical capital, social capital, and human capital have not real influence on farmers’ attitudes in implementing the jajar legowo system. 3) Farmers who implement the jajar legowo system are 21 farmers (70%) and those who do not implement it are 9 farmers (30%).

Abstract

Acne is a skin disease that often occurs in adolescence and even adulthood, characterized by the presence of blackheads, papules, pustules, nodes, and cysts on the face, neck, upper arms, chest, and back. Although not life-threatening, acne can affect a person's quality of life by giving a bad psychological effect in the way a person assesses, perceives and responds to his condition and situation. The aim of this study is to asses the antibacterial activity of the extract and fraction of the macroalgae Euchema cottonii against acne-causing bacteria, namely Propionibacterium acnes and Staphylococcus epidermidis. The extraction method used was maceration, using 96% p.a ethanol as a solvent and fractionation using the ECC method with three solvents with different polarity levels, namely n-hexane, ethylacetate and ethanol. The activity test was carried out using the paper disc and micro dilution method with the comparison antibacterial clindamycin. The results showed that there was no antibacterial activity from either the extract or fraction of macroalgae Euchema cottonii against the bacteria Propionibacterium acnes, but there are activity from the extract and fraction (n-hexane and ethylacetate) against the Staphylococcus epidermidis bacteria with the MBC value at a concentration of 15% and MIC at a concentration of 5% (for the extract and n-hexane fraction), while for the ethylacetate fraction the MIC value was at a concentration of 10%. Therefor, the strength of the antibacterial activity of the extract and fraction of Eucheuma cottoni is in the weak category.
