Abstract

Chilli is an economically valuable horticultural crops.  The exploration of local chilli genetic resources is expected to provide qualitative and quantitative character information.   The study aimed to test the appearance of local chilli genotypes in West Sumatra based on qualitative and quantitative characters.   The research was conducted on dry land in Tiaka Village, East Payakumbuh Subdistrict, Payakumbuh City, West Sumatra Province at an altitude of 515 m above sea level.  The research was carried out from December 2020 to August 2021.   The research used a fully randomised complete group design (RKLT) with 4 Treatmen 6  replications.  The chilli genotypes tested were; Aka, Keriting Bukittinggi, Gero and Kopay.  Variable observation of qualitative characters consisted of; anthocyanin staining on hypocotyl, stem colour, stem cross-sectional shape, leaf shape, leaf colour, flower shape, flower petal colour, flower crown colour, stigma colour, young fruit colour, old fruit colour, fruit shape, seed shape and seed colour.  Quantitative traits were: plant height, stem diameter, flowering age, harvest age, fruit length, fruit diameter, number of fruits per plant, fruit weight, fruit weight per plant, fruit weight per plot, fruit weight per ha. Data for quantitative characters were analysed using PKBT-STAT 3.1C statistical software.  Data for the quantitative characters leaf length, leaf width and 1000 seed weight were not statistically analysed.  The results of the study concluded that Aka is one of the candidates for superior varieties.  Aka chilli produces a lot of fruit (166.27 fruits/plant) with fruit weight reaching 26.95 tons/ha heavier than the Kopay variety as a comparison with fruit weight reaching 22.60 tons/ha.

Abstract

Yellow pumpkin is rich in vitamin A, carotene, and other essential nutrients, and has good durability. Apart from being a food and vegetable, pumpkin can be processed into semi-finished flour which becomes a processed product. This study aims to examine the effect of sodium tripolyphosphate (STPP) concentration on the physical and chemical properties of modified pumpkin starch (Modified cucurbita moschata starch). This study used an experimental method in the laboratory with a completely randomized design (CRD). The concentrations of STPP used in the treatments were 0.1%, 0.3%, 0.5%, 0.7%, and 0.9% of the weight of pumpkin starch. Each treatment was repeated 3 times, totaling 15 experimental units. Parameters observed included solubility, swelling power, moisture content, and starch content. Data were analyzed using analysis of variance (Anova) with a real level of 5% and Least Significance Different (LSD) further test. The results showed that STPP concentration had no significant effect on solubility and swelling power, but had a significant effect on the moisture content and starch content. The higher the STPP concentration, the higher the water content and the lower the starch content. The 0.9% STPP concentration had the highest moisture content (15.54%) and the 0.3% STPP concentration had the highest starch content (92.63%).  In order to be more complex, further research is carried out to test the parameters of phosphate content, ash content, amylose content, amylopectin content, color, PH, viscosity, anthocyanins, crude fiber, gelatinization, syneresis, antioxidants, polyphenols, reducing sugar, water holding capacity and oil holding capacity.

Abstract

One of the causes of low productivity in cucumber plants is due to low soil quality due to low organic matter content and high sandy soil mixture. Considering this, it is necessary to try to improve it. So, there is a need for research that examines the addition of organic matter and combines sandy media with paddy soil.This research took place in Pecoro Village, Jember Regency from May 2022 to July 2022. The research method was in the form of a Completely Randomized Design with the first treatment, namely the addition of baglog waste compost and cow manure (K1); baglog waste compost and goat manure (K2); and compost baglog waste and chicken manure (K3). While the second treatment is sandy planting media consisting of: sand 100% (M0); 75% sand + 25% paddy soil (M1); 50% sand + 50% paddy soil (M2); and 25% sand + 75% paddy soil (M3). The observed variables included plant height, total fruit weight, fruit unit weight, fruit length and fruit diameter which were tested by means of variance and Duncan's Multiple Range test.The results showed that the treatment of compost, sandy planting media, and their interactions had a significant effect on the observed variables. The recommendations given based on the results of the analysis for cucumber cultivation are the need to add organic matter such as compost mixed with baglog waste and manure from cow, goat and chicken manure with a ratio of 25% sandy planting medium to 75% paddy soil.

Abstract

Purworejo is one of the Arabica coffee producers with a plantation area of 529 hectares and production reaching 171 tons. This potential encourages the emergence of MSMEs that process coffee and one of them is Seplawan coffee. This study aims to determine the impact of implementing digital marketing on sales of Arabica coffee with the Seplawan brand, and to find out the differences in sales of Arabica coffee before and after implementing digital marketing. The research method uses case studies, and the determination of research locations is by purposive sampling. Data analysis used descriptive analysis and different test (t test) with a significance level of 95%. The results showed that the use of digital marketing had an impact on increasing sales of Seplawan coffee. Significant differences in coffee sales at the stage before and after being established in using digital marketing are found in sales of coffee sizes of 100 grams, 500 grams and 1000 grams.

Abstract

Mangrove plants (Avicennia marina) come from the Avicenniaceae family. The leaves have antioxidant, antiviral and antibacterial activity caused by the content of secondary metabolites in mangrove leaves in the form of flavonoid compounds. Research on the total flavonoid content of 96% ethanol extract and the water, ethyl acetate, and n-hexane fractions of A. marina leaves has never been carried out. The aim of this study was to determine the total flavonoid content in extracts and fractions of A. marina mangrove leaves by UV-Vis spectrophotometry method. Extraction was carried out using 96% ethanol solvent by sonication method, then fractionation was carried out using the liquid-liquid fractionation method. The extracts and fractions obtained for their secondary metabolites were identified by test tube and thin layer chromatography and then the total flavonoid content was determined by the colorimetric method. Mangrove leaf extracts and fractions contain secondary metabolites of flavonoids, phenolics, saponins, steroids, triterpenoids, and alkaloids. The results of thin layer chromatography confirmed the results of the tube test that mangrove leaf extracts and fractions contained flavonoid compounds. Total flavonoid content in 96% ethanol extract, water fraction, ethyl acetate fraction, and n-hexane fraction of A. marina mangrove leaves were 19.37; 3.07; 11.30; and 56.62 mg quercetin equivalent/gram sample. In conclusion, the total flavonoid content of A. marina leaves was high, thus supporting its activity as an antioxidant.

Abstract

Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.
