Abstract

The production of fish protein hydrolysate from common pony fish yields a fraction rich crude fish oil as a by-product. To utilize this by-product, refining is necessary to obtain common pony fish oil. This research aims to use a fraction rich crude fish oil from fish protein hydrolysate by-products to obtain fish oil and to determine the optimal conditions for the refining process using the response surface method (RSM) in the degumming, neutralization, and bleaching processes. The experimental design used was the Box–Behnken design, with the responses used to determine the optimum conditions at the degumming stage were water content and total dissolved solids. The response used to determine the optimum conditions at the neutralization stage was the refining factor, and at the bleaching stage was color (L, a*, b*). Parameters studied for each purification process include heating temperature (50-80°C), contact time between fraction rich crude fish oil with auxiliary materials (10-20 minutes) and the length of time for centrifugation (5-15 minutes) with a rotation speed of 10,062 G. The optimal conditions obtained in the degumming, neutralization, and bleaching processes for heating temperature, contact time between fraction rich crude fish oil with auxiliary materials, and centrifugation time, respectively,  were 50°C, 10 min, 5 min; 50°C, 20 min, 5 min; and 80°C, 10 min, 15 min. Verification of the optimum conditions resulted in a free fatty acid value of 8.25% ± 0.01%, an acid value of 1.87 ± 0.02 mg KOH/g oil, a peroxide value of 1.04 ± 0.01 meq/Kg, an anisidine value of 11.11 ± 0.01 meq/Kg, a total oxidation value of 13.21 ± 0.01 meq/Kg and water content 6.052 ± 0.02 %. These results indicate a reduction in free fatty acids, acid number, peroxide number, anisidine number and water content by 66%, 90%, 73.5%, 61%, 63%, and 92% respectively. Our results showed that the purified fraction rich crude fish oil has met the SNI standards in parameter acid number, peroxide number, iodine number, anisidine number, and total oxidation value. The purification process that has been carried out can improve the quality fraction rich crude fish oil, but further processing still needs to be carried out to reduce water content and free fatty acid value

Abstract

The increase in demand for sweet potatoes was not accompanied by an increase in production caused by a reduction in the area planted with sweet potatoes due to land conversion from wetlands to marginal lands. However, the available land for the expansion of agricultural areas is dominated by acid soils that are poor in nutrients. The main problem of planting in acid soil is the high content of Aluminum (Al). One of the effective approaches to selecting plants that are resistant to Al is using the solution culture method by adding Al and adjusting the pH of the solution. This activity aimed to obtain and develop the most appropriate and efficient screening method for selecting the resistance of some sweet potato germplasm to Al stress. The plant materials used were several collections of sweet potato germplasm, namely: Antin 1, Antin 3, Beta 1, Beta 2, Kidal, Papua Salosa, Sari, and Sarwentar. The research activities included: (1) Screening of sweet potato shoots in Al solution culture media in the form of AlCl3.6H2O with concentrations of 0, 100, 200, 300, 400, and 500 mg/L with a solution pH of 4.0 and (2) Testing of sweet potato Al tolerant on acid soils, namely yellow red podzolic soil from Bagoang Jasinga Village, Bogor Regency, Indonesia with a pH of 4.4-5.2. The results obtained were two sweet potato varieties that were tolerant of Al and acid soils, namely Kidal and Papua Salosa. Both of these varieties can be used as Al-tolerant and acid-soil-tolerant sweet potato planting material. Meanwhile, Antin was used as a comparison plant material that was intolerant of Al and acid soil.

Abstract

This research aims to determine the influence of liquid biofertilizer BRE4 and organic fertilizer on soil nematode diversity in Arabica coffee plantations. The study was conducted in smallholder Arabica coffee farms in the Ijen Bondowoso region, Indonesia. The research utilized a Randomized Complete Block Design with the following treatments: P1= 30 ml of liquid biofertilizer BRE4 per ton of manure, P2= 60 ml of liquid biofertilizer BRE4 per ton of manure, P3= 90 ml of liquid biofertilizer BRE4 per ton of manure, P4= 120 ml of liquid biofertilizer BRE4 per ton of manure, K- = Without liquid biofertilizer and manure, K+1= 60 ml of liquid biofertilizer, and K+2= 5L of manure without liquid biofertilizer. The results showed that the P4 treatment reduced the population of parasitic nematodes and increased the diversity of free-living nematodes better than other treatments. A total of 18 genera of soil nematodes were identified, with the bacterial-feeding nematode genus (bacteriovore) being the most abundant compared to other trophic groups. The application of BRE4 and manure improved the soil ecosystem based on the nematode diversity level.

Abstract

The presence of bobontengan weed (Leptochloa chinensis) in rice fields is considered to be detrimental and need to be controlled. Compounds secondary metabolites plant can be used as herbicides for weed control. Cacabean (Ludwigia hyssopifolia) is one of the plants that contain secondary metabolites compounds. This study aimed to determine the potency of the extract of each part of cacabean plant and the level of concentration in germination and growth of bobontengan. The research was carried out from February to March 2023, in the Integrated Field Greenhouse, Faculty of Agriculture, University of Lampung. The research design used a Randomized Block Experiment Design (RAK). The treatment consisted of two factors with four groups. The first factor was the source of cacabean extract: leaves, stems and roots, while the second factor was the concentration of cacabean extract which consisted of 4 levels: 0, 5, 10 and 15%. The homogeneity of variance was tested by Bartlett's test and the additiveness of the data was tested by Tukey's test. If the assumptions are met, the data is analyzed by analysis of variance and differences in treatment mean values followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that extracts of leaves, stems and roots of cacabean at concentrations of 5, 10 and 15% effectively suppressed seed germination and bobontengan weed growth. L.hyssopifolia leaf extract was most effective in suppressing germination, shoot height growth, and dry weight of bobontengan weed. Cacabean leaves and stem extracts were most effective in suppressing the percentage of germination, shoot height growth, and the total dry weight of bobontengan. Concentration of 15% of Cacabean extract was most effective in suppressing the growth of shoot height of 2 MSA, root length, and dry weight of bobontengan, while the concentration of 10-15% was most effective in suppressing the percentage of germination and shoot height of 4 MSA. Sources of cacabean leaves, stem and root extracts were influenced by the level of extract concentration in suppressing seed germination and crown height.
