Oryctes rhinoceros beetle is one of the pests that attacksimmature oil palm plants.This pest attacks oil palm plants in larvae or imago phase. This pest is usually damaging the respiratory roots, trunk bark, dry petiole,or periphery crown of oil palm leaves which can interferes the leaf growth and finally reduce the production even collapse the tree. Chemically pest control have the positive impact with faster pest death beside the negative impacts such as resistance, resurgence, disturbing human health and also environmental and ecosystem pollution. Biological control is one alternative pest control that is safe for the environment and can reduce chemical residues in agricultural products and environment. This study was conducted in Medan Denai district on July – Agustus 2019. This study aimed to determine the effect of the use of Beauveria bassiana and palm oil mill effluent to control Oryctes rhinoceros larvae. The method used in this study is a two factorial randomized block design (RBD), with 2 replications. The results of this study showed that the best density of Beauveria bassiana spores in controlling Oryctes rhinoceros larvae was 109 spores / ml and 50ml LCPKS (I2Q2) with death time of 40 hours, daily mortality 60%, total mortality 100%.

The expansion of oil palm plantations has led to debate over the negative impacts on soil fertility, hydrology, biodiversity and global warming. Climate change occurs due to changes in the composition of the atmosphere, mainly due to an increase in the concentration of greenhouse gases (GHGs). The usefulness of photosynthesis using CO2 is important to note. The purpose of this study is to measure / estimate the stored carbon absorbed by the 13-year-old Socfindo palm oil plant in the land suitability class S3. The study was conducted in May to June 2019 at PT Aek Torop Kebun III. Using descriptive design with Destructive and Non-Destructive methods based on ICRAF. The parameters are Above Surface Biomass (BAP) and Substance Biomass (BTB). The results showed that the oil palm surface surface biomass (BAP) at the age of 13 years was 117,855 tons / ha. The results of observations of Undergrowth Biomass (BTB) are 0.392 Ton / ha, the potential carbon stored is 54.394 Ton C / Ha and carbon dioxide absorption is 199.625 Ton CO2 / Ha.

The productivity of oil palm plants is influenced by genetic factor planting materials, soil, climate, cultivation and plant maintenance. Nursery is the first step to prepare the prime plant material. In the implementation of the nursery, fertilization is one important maintenance factor and should be done with reference to 4T (Exactly Types, Dosage, Time and Method). Loss of fertilizer is an important thing to be controlled. This research is a conservation action by packing fertilizer in sachet bag and conservation treatment. The research was conducted in January 2019 – July 2019 at STIPAP. The study used a non factorial randomized block design with S one sowing system, S two, S three, and S four sachet systems of different sizes using conservation. The best treatment is the application of gauze sachet system (S four = 638 mesh) with conservation increasing the growth of seedling height (91,36 cm), stem diameter (50,80 mm), increasing chlorophyll (55,62 cci), increasing root wet weight 99,73 (44%) and canopy dry weight 55,10 (44%).

One way to produce good seeds is from fertilization factors, both artificial fertilizers or biological fertilizers. Palm oil growing media is soil in which there are several nutrients needed by plants, one of which is Phosphor (P). The role of P in plants is important for cell growth, formation of fine roots and root hairs, strengthening the stem stands. However, there are still many P nutrients that are bound in the soil so with that one effort to overcome the low phosphate available in the soil is by utilizing a group of microorganisms. Microorganisms and organic matter, each of which can produce organic acids that chew metal in the soil so that phosphate becomes available to plants.

Fertilization in oil palm plants plays a very important role, more than 50% of the cost of the plant is used for fertilization. The hybrid oil palm currently being developed is generally very responsive to fertilization. Fertilization is a very important factor to increase the productivity and quality of the production produced. Fertilization is useful to provide nutrients needed by plants in order to carry out physiological processes that produce good growth and production. Fertilization costs are relatively high, approximately 30% of the total production costs or 40-60% of the total maintenance costs. The costs required to carry out fertilization activities are very large so that proper fertilization planning is needed to be effective and efficient. In productive plants can be done effectively 4T fertilization techniques, namely the right type, right dose, right on target, and on time. Based on this, observations were made on the study of fertilizer costs on plantations. This research was conducted in Division F of Sei Kalam Gardens, PT. Asam Jawa, Labuhanbatu Selatan Regency, North Sumatra Province. The time for the research to begin in March 2019 until May 2019.
