Abstract

The Andong Merah plant (Cordyline fruticosa) is known to have natural antibacterial properties, which can inhibit the growth of cancer and tumors. Several studies that have been carried out previously showed the potential of red Andong Merah plant extracts for health, especially in the Andong Merah leaves with many active compounds. This study explored the potential of Andong Merah leaves for their phytochemical analysis, antioxidant and antibacterial activity. Andong Merah leaves were macerated using n-hexane, ethyl acetate, and ethanol solvent to yield the crude extracts. The phytochemical analysis was evaluated by the Harborne and Kokate method. Antioxidant activity was evaluated by DPPH radical scavenging assay. Antibacterial activity was examined using the agar well diffusion method against Propionibacterium acnes, Streptococcus mutans, and Streptococcus sobrinus. The results showed that the Andong Merah leaves extract contains alkaloids, flavonoids, tannins, steroids, and saponins. The antioxidant activity test showed that the n-hexane and ethyl acetate of Andong Merah leaves extracts displayed the ability to inhibit DPPH free radical by 74% and 75% at 200 ppm concentration, while ethanol extracts by 79% at 100 ppm concentration. The antibacterial activity showed that the ethanol extract of Andong Merah leaves displayed the ability to inhibit the Propionibacterium acnes growth with 12 mm inhibition activity at 400 µg. The ethanol and ethyl acetate of Andong Merah leaves extract can inhibit the Streptococcus mutans growth with 9 mm at 400 µg. Antibacterial activity of n-hexane, ethyl acetate, and ethanol extract of Andong Merah leaves display the ability to inhibit the Streptococcus sobrinus growth with 10 mm at 400 µg concentration. Based on the results, Andong Merah leaves (Cordyline fruticosa) display potential as a natural antioxidant and antibacterial agent.

Abstract

Many accidents in oil palm plantations are caused by risks such as harvesting activities. Even though the K3 system has been implemented, accidents still occur because there is a high potential risk of work accidents, so companies need to manage them so that the level of work accidents can be reduced. Research objectives: identify potential dangers and risks of work accidents for harvest employees, carry out an assessment and analysis of the level of value of the risk of harvesting work activities using the HIRARC method and recommend ways to control the potential risk of work accidents during harvesting based on the K3 risk management hierarchy, namely substitution, elimination, PPE and administration. Activities identified as having potential dangers and risks are sharpening tools, cutting fruit, cutting midribs, transporting fruit to TPH, and arranging fruit in TPH. There are 2 levels of risk assessment, namely low risk low risk (sharpening tools, cutting fruit at risk of being injured by thorns and the risk of material waste being exposed to sore eyes, arranging fruit in TPH), medium risk, medium risk (cutting the fronds at risk of falling fronds, swelling from wasp stings and fever, transporting fruit to TPH), and controlling risks such as substitution, elimination, using PPE, administration and being careful when working and paying attention to land conditions.

Abstract

This research is motivated by the importance of knowledge about alternative pest control that is safe but still supports the achievement of maximum oil palm production so that the balance of the oil palm plantation ecosystem can occur. The purpose of this study is to determine the technical cultivation and benefits of the Turnera subulata flower as a host plant for predators and parasitoids that function as biological agents for caterpillars and can be a reference for controlling caterpillar pests that are safe and still support the achievement of maximum oil palm production. The method used in this research is field observation and documentation from the company. The scope of this research covers the technical aspects of the biological control of caterpillars. This research data uses primary data and secondary data obtained from field observations and literature studies in the form of company reports in the form of percentages. The realization of Turnera subulata planting reached 21,659 m on CR road and 19,914 m on MR road. The planned planting of Turnera subulata is 57,200 m on the CR road and 45,823 m on the MR road. For the realization of the planting of Turnera subulata itself using seeds that are ready for planting. To obtain the seedling, the company conducts its nurseries. The seedling technique was done using the stem cutting technique. The stems for the cutting technique were taken from the Turnera subulata plant stems that have grown large. The type of stem taken is the old Turnera subulata plant stem. For seed care, the seeds are always watered every morning and evening like other flower plants. For the natural enemy insects, been proven that there are 6 natural enemy insects associated with Turnera subulata plants, 3 predators, and 3 parasitoids, each with a large enough number of insects. The types are Eocanthecona furcellata, Cosmolestes sp., Sycannus dichotomus, Spinaria spinator, Fornicia sp., and Chaetexorista javana. The development and the implementation of a control system are by optimizing the conservation and utilization of these biological control agents is a wise step to obtain an effective, efficient and environmentally friendly technique for controlling caterpillars. The presence of Turnera subulata plants can be used to suppress the development of pests in oil palm plantations by increasing the potential for natural enemies, both predators, and parasitoids. The diversity of wild plants with flowers can increase the variety of insects so that the balance of the ecosystem occurs.

Abstract

This research is motivated by the processing of palm oil, transportation factors get special attention.The transportation of palm fruit from the garden to the factory should be as fast as possible so that thefruit harvested today can be processed directly so that free fatty acids are not high. Extensive oil palmplantations and garden conditions far from the factory, it will be more difficult to regulate the entry ofFresh Fruit Bunches (TBS) to the Palm Oil Factory (PKS), so that the company must have a goodmanagement system that can run effectively and efficiently so that it needs proper transportation forperushan so that it can transport all tbs harvested by minimizing time, cost and maintain the quality ofTBS.From the description above, the formula that can be formulated in this study is to know the time oftransportation, the needs of transport equipment and what obstacles are encountered at the time of TBStransportation. While the limitations of the problem there is tbs transport research contained in fadelingBrafo, Alfah and Delta with different distances (near, medium and farthest). The purpose of this researchis to know the process of planning the needs of TBS conveyances, as well as knowing the obstacleswhen transporting TBS.The results of research conducted at PT. Berau Karetindo Lestari shows that tbs transportationplanning includes the production of TBS per day, TBS transport time, availability of conveyance,transportation needs and constraints in transportation. In Bravo afdeling requires 2 units of tarktor, forafdeling Alfah 4 units taktor, and afdeling Delta requires 3 units of tractor. As for the needs of the truckon Loading ramp 1 as many as 10 units and Loading ramp 2 to 8 units. This is obtained after calculatingthe number of transport equipment needs to transport TBS every day. For the overall needs of thecompany, tractors are needed as many as 17 and DT as many as 18 units. As for the obstacles at thetime of tbs transportation, namely, the road conditions in TPH are not good and the distance of thefactory is so far that it takes so much time to get to the factory.
