Design of Centrifugal Pump for Palm Fruit Pulp Handling in Palm Oil Plant.

Potassium is a macro nutrient that can affect the quality and quantity of oil palm bunches as well as resistance to disease and drought stress. So far, testing the status of potassium nutrient uptake in people's plantations in Perlabian Village, Kampung Rakyat Labuhanbatu Selatan District has never been carried out. Fertilization and maintenance are carried out through knowledge from generation to generation, so it is important to have a study on the nutrient uptake status of potassium in oil palm leaves. This research was conducted using a free grid survey method at the semi-detailed survey level with a density of 100 meters. A total of 6 leaf samples were taken on the 17th leaf midrib and then rubbed with 70% alcohol and then put into the plastic sample for further testing in the laboratory of PT. Socfindo. The results showed that the potassium in leaf samples 1, 3 and 4 experienced deficiency and leaf samples 2, 5 and 6 were at the optimum. In oil palm plantations in smallholder plantations in Perlabian Village, Kampung Rakyat Subdistrict, it shows that the total K content of leaves is included in the optimum category.

The global population growth and changes in human lifestyle and consumption patterns put immense pressure on the limited freshwater resources in the world. Aiming at sustainable use and equitable allocation of the water resources, it becomes crucial to know the water appropriation for the production of different commodities and consumer goods. These days, oil palm (Elaeis guineensis) is one of the highest-demanded crops around the globe since the oil of its fruits and kernel is widely used as biofuel and major ingredients in food and cosmetic industries. Given this massive demand, the areas under oil palm cultivation in the tropics have continuously been expanding in the last decades, particularly in Indonesia. With the oil palm boom, not only biodiversity loss, and carbon dioxide emissions from deforestation have been increasing, but also the consumptions of blue and green water resources are of concern.&#160;In this ongoing research, the concept of water footprint (WF) is employed to quantify the green and blue water use of oil palm production in the Bajubang district, Batanghari regency, Jambi province, Sumatra, Indonesia. This is one of the first studies that uses field-measured data of evapotranspiration (ET) from oil palm plantations in different growth stages over seven years for the purpose of WF assessment, compared to the available literature where ET was estimated using modelling approaches. The multi-year measurements were conducted using the eddy covariance technique, which continuously measures water vapor (H2O) fluxes at the ecosystem level over the plantation. Based on these measurements, specifically, the WF assessment is performed on a product basis during the plantation life cycle, per area and time unit, for the oil palm fruit yield and oil palm derived products (palm oil, palm-oil biodiesel). Besides the crop water consumption at the plantation (i.e. ET) as the core element, other water consumptions in the products&#8217; processing chain are included in the WF assessment. Preliminary results indicate a WF of 2440 m3 t-1 for palm oil and 65 m3 GJ-1 for palm-oil biodiesel. This is about 50% lower than the global average estimates. Local WF account of oil palm products has a critical contribution to product transparency while being useful for comparative purposes. Contrasting the WFs of products serving the same function (e.g., palm oil biodiesel, soybean biodiesel) is of essential importance, aiming at conscious product choices in a world of freshwater scarcity.Keywords: water footprint, oil palm, palm oil, Indonesia, eddy covariance, evapotranspiration

Fruit Processing

The oil palm (elaeis guneensis) is a very important economic crop in West Africa where it is native. The fruit bunch contains 23 to 30% oil and is the highest yielding of all vegetable oil crops. Palm oil is the second most important vegetable oil in world consumption and the first to be commercialized internationally. Africa and indeed Nigerian was the world’s highest producer of palm oil prior to 1961. Today, Nigeria is the fourth largest producer after Indonesia, Malaysia and Thailand. One of the main reasons given for this fall is lack of efficient mechanized processing equipment for the small-scale producers who produce over 80% of the country’s palm oil. Their methods of production are labour intensive, batch, tedious, inefficient, and produce poor quality oil, have low throughput, unable to extract palm kernel alongside palm oil and so productivity is low and products (palm oil and palm kernel) lack competitiveness. This work has developed a mechanized oil palm fruit processing mill with six fully integrated systems for extracting good quality palm oil and palm kernel, while utilizing process wastes as the main source of heat energy. Each system/unit is expected to operate at the best quoted system efficiency. Tests are ongoing to determine and confirm these efficiencies.

The Indonesian government has a vision to become the world's best sustainable palm oil producer with the aim of producing 40 million tons of palm oil in 2020 for food and for energy. The country must produce must double in the next 10 years. This condition raises black campaign from various parts of the world. Palm oil is a destroyer of the earth, but on the other hand the potential for food security in the world plays a very big role, especially for edible oil and energy.. This study aimed to determined the oil extraction rate in crude palm oil and minor components (tocol content and beta-carotene) at altitudes of 650 meters above sea level and 850 meters above sea level. This study used a completely non-factorial randomized design with parameters of unriped, riped and over riped. The results showed that the maturity level of oil palm fruit affected the oil extraction rate, beta-carotene, tocol content (tocopherol and tocotrienol) of crude palm oil produced at altitude of 650 meters above sea level and 850 meters above sea level. Riped fruit has high oil extraction rate, and the minor component were measured by tocol content and beta-carotene contained in crude palm oil.

By Products

The vast palm oil plantations in Riau province which are 2,430,500 hectares (BPS Indonesia, 2017) have great potential as a provider of CPO (Crude Palm Oil) and other by-products and include waste. The midrib is always lowered along with the decrease in oil palm fruit bunches at harvest. Handling of waste from the midrib is only by stacking it in the field and letting it dry and self-destruct. Oil palm midribs are still a problem today because they can affect the global climate with greenhouse gas emissions. Carbon emissions can still be minimized by utilizing oil palm midribs. This study aims to measure the reduction of CO2 emissions as an added ingredient in the production of fiber CLC. Presentation of research results using descriptive methods. Research conducted in laboratories with an experimental approach is quantitative. The findings of this study are that the use of oil palm fronds as an added ingredient in producing CLC of solar and electric fuel fibers by 1 m3 can reduce CO2 emissions. The conclusion of this study is that CO2 emissions that can be reduced in the manufacture of 1 m3 of fiber CLC using diesel fuel is 111,582 tons/year and when using an electrically driven engine the CO2 emissions that can be reduced are 120.887 tons/year.
