Abstract

One of the successes of processing at the Palm Oil Mill (POM) is the quality of the raw material for Fresh Fruit Bunches (FFB). The degree of maturity of FFB at harvest is related closely to CPO oil content and free fatty acid content (FFA). One of the varieties grown on oil palm plantations is the DxP Bah Lias variety produced by Bah Lias Research Station (BLRS). The study was conducted in April - June 2017 at the Laboratory of PT. Betami in Kuala Simpang, Aceh Tamiang. FFB samples were obtained from Division I of the Rantau Garden PT. Betami. The study aims to determine the effect of maturity fraction of oil palm FFB on the levels of CPO. The fractions studied were 0, 1, 2, 3, and 4 fractions. The results showed that the highest CPO yield was fraction 3, 26.1% and the lowest fraction 0 with a yield of 22%.

Abstract

One of the main obstacles in rubber cultivation is the white root fungus (JAP) attack which caused by Rigidophorus ligonosus. This pathogen infects rubber plants from the nursery until the mature plants. Efforts to control the disease have been carried out by chemical, technical culture and use of biological agencies. This research was conducted at the STIP-AP Medan in January 2017 to June 2017, this study used a non-factorial Randomized Block Design (RBD) with four replications and four treatments. Using Trichoderma koningii with somes doses were 20 grams, 30 grams, and 40 grams/seedling. The results of this study indicate that the biofungicide application of Trichoderma koningii 30 g/seedling produces the greatest inhibition of the rubber plants seedling nursery against the growth of pathogens Rigidoporus lignosus.

Abstract

Mesocarp or fruit flesh is the main component of the cultivation of oil palm which is extracted to Crude Palm Oil (CPO). The amount of CPO produced from processing in palm oil mills is influenced by the quality of Fresh Fruit Bunches (FFB). Some factors that influence the quality of FFB are the type of crossing, plant age, maintenance level and fraction of fruit maturity. Adequacy of nutrients N, P, K, and Mg play a role in fruit formation and are expected to increase levels of CPO. In connection with this matter, research on the relationship / nutrient correlation with CPO content is needed. This research was conducted in October 2017 - March 2018 in the field with land suitability classes S1 (Maradja Hill), S2 (Limau Mungkur), S3 (Bah Birung Ulu) and STIPAP LPP Medan Practice Gardens. Processing data with single and multiple linear regression. Leaf samples were analyzed with the Sochlet apparatus in STIPAP Processing Laboratory. In general, the average nutrient content of leaves N, P, K were the normal category and nutrient Mg, Cl were deficiency category. The level of CPO (oil / mesocarp) varies from 31.14% - 59.59%. With single nutrient regression N, P, K, Cl has a positive correlation with CPO levels while Mg is negatively correlated. Multiple regression analysis of nutrient N, P, K, Mg and Cl has significant effect on O / N with a correlation coefficient of 0.744.

Abstract

Latex is a colloidal suspended of rubber particle in rubber tree (Hevea brasiliensis). Technically, the capacity of rubber productivity can be determined by latex collectionperiod after being tapped. The objective of research was to obtain the differences of latex collection period. The study was conducted in September-November 2017 at the Sungei Putih Research Center in Experimental Estate with PB 260 (7 years tapped) on BO-2 (S/2 d3.ET2.5% Ga1.0 6/y(m)).The experimental designused a Randomized Block Design (RBD) with four treatments of latex collection periodi.e 20, 40, 60, 80 minutes after being tapped with three replicates respectively. The parameters observed was gram/tree/tapping (g/p/s), kg/ha/years, latex flow rate (ml/minutes) and total solid content (%).The results showed that latex collection period was significantly different to g/p/s, kg/ha/years and latex flow rate. Total solid content (TSC) was not significantlydifferent in all treatments. The latex collection period of 20 minutes after being tapped had higher productivity than 40, 60, 80 minutes.

Abstract

Serratia sp is the family Enterobacteriaceae gram-negative bacteria that have flagella Peritrik, motile and reported to be anti-fungal. Chitinolytic chitinase activity of bacteria are potentially used as a biological control against pathogenic fungi.The purpose of this research is to know the potential of bacteriaSerratia sp in controlling white root rot disease caused by Rigidoporus microporus on the rubber plant in polibag. This research uses a randomizedblock design (RAK) nonfaktorial with 5 treatments and 5 replications. Parametersmeasured were extensive white root fungus colony growth (cm) in the laboratory,white root fungus attack intensity (%) in polybag, the percentage of inhibition (%)in polybag and visual symptom of the white root fungus attack in polybag. Thereault of this showed that Serratia sp bacteri application infection very obvious inobstructing extensive growth of the white root fungus colony in Laboratory, withthe lowest extensive of colony 3,06 cm on D4 standard (10ml/100 ml PDA) A verysignificant effect in reducing the intensity of white root fungus attacks the inhibition rate reached 54%, or healing reached 47,31% the age of 6 weeks after application.

Abstract

Sycanus annulicornis is an important predator for palm leaf-eating caterpillars (UPDKS) from the Limacodidae family. Therefore, these predators need to be propagated and disseminated in the area of ​​oil palm plantations so that they can become a mortality factor in biological control (UPDKS). Predator S. annulicornis is a predator that is very useful for controlling caterpillar pests in oil palm plantations. His ability to prey on fire caterpillars in the field, as well as his short life cycle and high reproductive ability make this predator very potential to be applied in fire caterpillar pest control. This research was carried out at Sycanus House Afdeling V Tanah Raja PT. Perkebunan Nusantara III Serdang Bedagai North Sumatra. The time of the study was carried out in August - September 2018. The results showed that fire caterpillar (Setothosea asigna) was able to be controlled by predators (Sycanus annulicornis) in F1 treatment (1 Sycanus annulicornis), F2 (2 Sycanus annulicornis) and F3 on the first day after application, the highest mortality seen in the treatment F3 (3 Sycanus annulicornis).
