Abstract

The productivity of oil palm fruit bunches increases rapidly and reaches a maximum at the age of 8-12 years, then decreases slowly with plants getting older to 25 years of economic age. This research was conducted in Afdeling V Kebun Lama PT. Perkebunan Nusantara I. This research was conducted in May until July 2018. This research was using descriptive analysis, by using oil palm productivity data in Afdeling V Kebun Lama PT. Perkebunan Nusantara I. The results showed that the average number of bunches per tree in 2015-2017 was 7.59% lower than the potential, the average bunch weight was 32.06% lower than the potential, and the average productivity of FFB was lower 37.47 % of potential. The gap in oil palm productivity in Afdeling V Kebun Lama PTPN I was influenced by several factors, namely rainfall factors, plant age factors, fertilization factors, number of tree stands per hectare (SPH), and plant disease factors.

Abstract

Oil Palm (Elaeis guineensis Jacq.) Is one of the important plantation crops in Indonesia. This plant produces vegetable oils that are important for the food industry and for fuel (biodiesel). Oil palm produces the highest oil unity of area compared to other types of plants with oil potential of around 6-7 tons/ha/year. The research was carried out in the greenhouse of the Plantation Agribusiness Institute of Higher Education (STIPAP). The study period was 6 months from September to March 2018. This study also used a non-factorial randomized block design with 3 times replication, the number of polybags per treatment was 3. Parameter tests were arranged on the variance list and Duncan's Multiple Range Test (DMRT) was tested level of 5%. The results of this study indicate that DyxP DUMPY varieties have good resistance to water stress. Dy×P Dumpy varieties were relatively more adaptable and gave better growth compared to other varieties in the condition of giving 1000 ml of water which was shown in observing the height increase of plants, increasing the number of leaves, increasing the diameter of the stem.

Abstract

Palm oil (Elaeis guineensis Jacq.) is Indonesia's leading and prime plantation commodity. The main products are palm oil (CPO) or palm kernel oil (KPO). Both of these products have high economic value and become one of the largest foreign exchange earners compared to other plantation commodities. Until now palm oil has been cultivated in the form of oil palm plantations and processing plants to become oil and derivative products. The study was carried out in the STIPAP greenhouse. The research period was 7 months, from September to March 2018. This research used Factorial 1 design with 3x replication, the number of polybags per treatment was 3. Parameter testing was arranged on the variance list and Duncan's Multiple Range Test (DMRT) was tested at level 5 %. The results showed that the DxP Avros variety had good adaptability to water stress, especially on stem diameter, leaf number, leaf area, amount of chlorophyll, number of roots, root length, number of stomata not significantly different between treatments A1, A2 and A3.

Abstract

The research was carried out in Molecular Biology Laboratory, Oil Palm Research Institute (IOPRI) Medan. The research was carried to examine genetic relationship between parents and their hybrids and to produce markers useful for purity hybrid testing. The analysis used in the study were RAPD. RAPD band profiles were used to detect genetic similarity among parents and progenies. Dendogram and correspondency matrix analysis were calculated by NumericalTaxonomy and Multivariate System (NTSys) versi on 2.02 sofware. This research used two populations consist of 20 progenies from BO5462D x BO5463D cross (population I) and 22 progenies from BO944T x BO713P crossing (population II), planted in Bah Jambi estate. The RAPD analysis was conducted by screening the primers gave polymorphic fragment among parent and the progeny. From 28 primers tested, 14 primers produced polymorphic marker, 11 primers monomorphic and 3 primers were unable to amplified. Among 14 primers thatproduced polymorphic bands, 7 RAPD were chosen, they OPJ-04, OPO-13, OPC-19,OPD-10, OPM-19, OPR-07, dan OPD-11. These 7 primers produced 52 bands. Primer OPJ-04 produced highest polymorphism loci (12 loci) and primer OPO-13 produced less polymorphism loci (4 loci). From the 7 primers used, there was 1 primer that can be used as genetic purity marker, this is primer OPD-11 and D_11_250 locus. Cluster analysis showed that population I, was clustered into 5 groups with genetic similarity around 62%. Group A consist of 8 progenies which were closely related to female parent and group B consist of 3 progenies closely related to male parent. Population II was clustered into two group (A and B) with genetic similarity 66%. Group A were devided into 6 sub groups, where sub group A2 consist of 8 progenies were closely related to female parent. Sub group A2, A3, dan A4 were closely related to male parent. Deviation analysis showed that in population I, there were found 3 off type progenies (number 3,8, and 15) and in population II, there were 4 off type progenies (number 26, 28, 30 dan 45).
