Abstract

In this study, weeds in oil palm plantations that produce, including Nephrolepis biserrata, have different resistance to single or combination herbicides, with a mixed herbicide of glyphosate 480 sl and paraquat is expected to control fern weeds (Nephrolepis biserrata) more effectively and efficiently than singly. carried out using a non-factorial randomized block design (RAK) with 3 treatments, namely, D0: Babat D1: glyphosate herbicide 480 sl dose 30 ml 5 liter water volume, D2: paraquat herbicide 25 ml 5 liter water volume, D3: glyphosate herbicide 480 sl + herbicide paraquat at a dose of 20 ml with a volume of 5 liters of water added with mechanical treatment repeated 4 times. Observation parameters in this study were weed mortality rate, leaf color poisoning rate and natality. The results showed that the best treatment was to use the herbicide paraquat (25 ml volume of water 5 liters) on day 13 the weeds had died, while in the herbicide treatment glyphosate 480 sl (30 ml volume of water 5 liters) suppressed weed death on day 19 in the herbicide treatment glyphosate 480 sl mixed with paraquat was able to suppress mortality on day 19 Keywords: plantation, weeds, herbicides

Abstract

Post-harvest technology for agricultural products has grown from time to time. One of the post-harvest technologies for agricultural products that is carried out is adding a coating material to the fruit to slow down evapotranspiration which increases the shelf life of papaya fruit. Papaya yields are increasing from time to time, this must be followed by handling the papaya harvest properly. This study aims to determine whether or not the effect of giving wax with oleic acid and tritenolamine solvents on the shelf life of papaya fruit and to determine the concentration of beeswax with oleic acid and tritenolamine solvents which are good for coating papaya fruit. The treatment parameters were wax coating with a concentration of 2%, 4%, 6% and control. Observations included fruit weight, fruit weight loss, fruit texture and organoleptic tests on fruit color, fruit aroma and fruit taste. The results showed that applying beeswax coating with oleic acid and tritenolamine solvent did not affect the shelf life of papaya fruit. The right concentration to coat the papaya fruit is wax coating with a concentration of 4%. Key words: Papaya fruit, wax coating, oleic acid, tritenolamine, shelf life, fruit quality

Abstract

Soybeans continue to increase linearly from year to year, but the realized results cannot meet the demand. This study aims to determine the effect of oil palm empty fruit bunch ash on soybean plant growth (Glycine max L.). This research was conducted in the village of Aek hitetoras, Marbau sub-district, North Labuhanbatu district, North Sumatra. This research was conducted from April to June 2021. The research design used was a non-factorial randomized block design (RAK) with 4 treatments, namely J0: (Empty bunches of ash 0 grams/plant). J1 : (Empty bunches of oil palm ash 300 grams/plant). J2 : (Empty bunches of oil palm ash 600 grams/plant). J3 : (Empty oil palm bunch ash 900 grams/plant). Parameters observed were plant height, number of leaves, leaf width, stem diameter. The data were analyzed using the average test with the level of ash of empty fruit bunches of oil palm.

Abstract

Palm flower is a plant that is widely distributed in the tropics. Originally from Madagascar, it was known as Madagascar periwinkle. The components of active compounds present in blood sites are phenolic acids, alkaloids, and flavonoids. Palm flower leaves contain a lot of flavonoid compounds that function as antioxidants, stimulate the production of nitrite oxidants (can dilate blood vessels), inhibit erythrocyte clumping, and can inhibit the growth of cancer cells. This study aims to observe the morphological characteristics and determine the content of phytochemical compounds in various varieties of palm flower (Catharanthus roseus) collection of the Labuhanbatu University experimental garden. The materials used in this study were 4 types of palm flower plant varieties collected by Labuhanbatu University. The method in this research is a survey with a qualitative approach to collect information related to the collected data. The results of observations of morphological characteristics were differences in stem color and flower color of palm flower and differences in flavonoids in each palm flower, and palm flower TW was palm flower which had the highest flavonoid content, namely 663.80. Keywords: Palm flower, morphology, flavonoids

Abstract

This study aims to compare the effect or effectiveness of the bridal tear plant (antigonon leptopus) which was dosed and onion extract (allium cepa) in the soaking process. This research was conducted in the village III Kampung Jawa Pulo Jantan, NA. IX-X sub-district, North Labuhanbatu Utara. This research was conducted from April to June 2021. The design used in the study was a randomized block design (RAK) which involves two (2) factors, including the first factor dosage composition and immersion time (K) with 4 treatments, namely: K0 = Kontrol; K1 = 5 ml; K2 = 10 ml; K3 = 15 ml. Second factor immersion time (L) with 3 treatments, namely: L1 = 8 hours; L2 = 16 hours; L3 = 24 hours. Parameters observed were rod length (cm), number of leaves (sheet), leaf width (cm), stem diameter (mm). As for the result obtained from this study, the highest average was found in the K3L1 treatment, namely a dose of 15 ml with an immersion time 8 hours and the lowest was found in the K0L1 treatment (without treatment).

Abstract

PTPN IV, the Berangir business unit, has some flat-sloping areas and most of them are hilly which are prone to erosion. Erosion needs to be known as early as possible so that land damage due to erosion can be avoided. This study aims to determine the level of erosion hazard that occurs using the USLE (Universal Soil Losses Equation) method at the PTPN IV oil palm plantation business unit Berangir Perkbunan Berangir Village, NA IX-X District, North Labuhanbatu Regency. This research was conducted from March to May 2021, using an exploratory descriptive method through a field survey, followed by using the USLE method to predict erosion. Parameters observed were rain erodibility, soil erodibility, slope length and slope, plants, and soil conservation measures. The results of this study indicate the level of erosion hazard ranges from 11,694-7819,104 tons/ha/year. The highest actual erosion value was found in the sample of 20 Afd V, which was 7819.104 tons/ha/yr with typic paleudults soil type and steep slopes. The lowest actual erosion value is found in sample 3 Afd I, which is 11,694 tons/ha/yr with psammentic paleudults soil type and gentle slope. Keywords: Plantation, Erosion, USLE (Universal Soil Losses Equation)
