Abstract

The purposes of this research were to get the best pH, and also to identify the ability of mixed culture of hydrocarbonoclastic bacteria in bioremediation of dirtied soil by oil refinery waste. The bacteria were used are Acinetobacter baumanni, Alcaligenes eutrophus, Bacillus sp1., Methylococcus capsulatus, Bacillus sp2., Morococcus sp., Pseudomonas diminuta, Xanthomonas albilineans, Bacillus cereus and Flavobacterium branchiophiia. Variation of pH were 6,5, 7,0, 7,5. Observed parameters in optimization were Total Plate Count (TPC) the culture every week, Total Petroleum Hydrocarbon (TPH) and Chemical Oxygen Demand (COD) examined at the end of the bioremediation period. Best optimization result then analyzed with GC/MS. The best pH was 7,5 with TPH degradation 73,241% and COD slope 86,283%. The chromatogram indicated that hydrocarbon compound from nC9 – nC32 have been degraded by 31,824% – 94,934%. The conclusions of this research were a good result of bioremediation was obtained from mixed culture inoculum at pH 7,5.

Abstract

Palm oil production in Riau continues to increase from year to year. The increase in palm oil production still has obstacles caused by pests and diseases, among others caused by pathogenic fungi, Ganoderma boninense, this fungus causes root rot disease. Control of stem rot disease is needed appropriate techniques, especially controls that are environmentally friendly. One of the uses of biological agents, such as Trichoderma, especially Trichoderma virens. This study aims to obtain a dose of Trichoderma virens that is effective in controlling Ganoderma boninense in oil palm pre nursery on peat medium. This research was conducted at the experimental field of the Faculty of Agriculture and Animal Husbandry of the State Islamic University of Sultan Syarif Kasim Riau. This research was conducted in December 2018 - March 2019. This research was a field experiment (experiment) using a Non Factorial Completely Randomized Design (RAL) by conducting Trichoderma virens test on oil palm seeds with various doses where each treatment was repeated 6 times there are 30 experimental units. The results showed that the parameters observed were macroscopic and microscopic fungi ,in-vitro test, speed of infection, intensity of disease attack, plant height, stem diameter and root root ratio. The results showed that Trichoderma virens fungi can reduce the intensity of fungal disease attack Ganoderma boninense given Trichoderma virens increased the growth of stem diameter of oil palm seedlings.

Abstract

Weed vegetation analysis is important to do in order to know the composition and structure of the vegetation to determine the appropriate weed control measures. This study aims to compare the composition and structure of weeds on peatland immature oil palm plantations and mature palm. This research was conducted from October to December 2020. Vegetation analysis was carried out using a survei method with purposive sampling technique. The parameters observed were density, frequency, dominance, important value index (INP), summed dominance ratio (SDR) and species diversity index (H'). The results showed that the composition of weeds on immature oil palm plantations was found 12 species with number of individual 847, while on mature palm found 9 species with number of individuals 980. The dominant weed structure on immature oil palm plantations is Lempuyangan with SDR values 29,9 % and mature palm is Bandotan with SDR value 23,4%. Weed diversity index on immature oil palm plantations and mature palm is categorized as high with a value of 1.50 for immature oil palm plantations and 1.65 for mature palm.

Abstract

Research was conducted from August until October 2011 at Agronomy Laboratory and research farm of Agriculture and Animal Science Faculty of State Islamic University Sultan Syaif Kasim Riau. Triploid watermelon of F1 Riendow was used in this experiment. The experimental design used was Completely Randomized Design arranged in factorial between alteration seed coats (with and without clipping the seed coat) and 4 different times of soaking with Atonik (0, 30,60 and 90 minutes) with 3 replications for germination experiment and soaking with Atonik (0, 30, 60 dan 90 minutes) with 6 replications for plant growth experiment. The research was conducted in the pot with peat soil. Result of the research showed that seed germination with clipping the seed coat (64.54%) was higher than without clipping the seed coat (38.28%). There was no interaction between alteration of the seed and soaking time. Soaking time with Atonik did not affect seed germination and also the growth of the plants (stem length, number of leaves, plant and root dry weight) at 55 days after planting.

Abstract

The problem of propagation of Punica granatum, was hard seed, and it difficult to germinate. One of the efforts to solve the problem is using H2SO4 as to breakdown of the hard seed. This study aimed to obtain the best concentration of H2SO4 and soaking time, as well as the interaction between H2SO4 concentration and soaking time on the germination of  Punica granatum seeds. This study used a completely randomized design (CRD) consisting of 2 factors. The first factor is H2SO4 concentration (0%, 20%, 40%, 60%, and 80%), and the second factor is soaking time (10, 15, and 20 minutes). Parameters observed were germination, germination rate, vigor index, germination height, root length, weight of sprouts, and dry weight of Punica granatum sprouts. The results showed the use of water was the best treatment on germination (85.30%), germination rate (17.37 days), vigor index (2.24%), germination height (7.80 cm), and root length of Punica granatum (7.05 cm), soaking time did not effect the germination of Punica granatum, and the interaction between the use of water and the soaking time 15 minutes was the best treatment on the parameters of fresh weight of sprouts (0.17 g) and dry weight of Punica granatum sprouts (0.13 g).
