Abstract

Lemongrass (Cymbopogon nardus L.) better known as lemongrass or citronella grass or citronella grass is a type of grass from the order Gramiales which is typical of tropical areas of Asia. But this citronella plant is also a plantation crop that has the potential to be developed in Indonesia. And this research has been carried out in my home plantation area in February – April 2022. This study aims to find out the effect of fertilizing goat cage and soil on the growth and results of circular plants. The application of goat manure and soil 2:1 showed the best in increasing the number of tillers, root fresh weight, crown fresh weight, leaf fresh weight, root dry weight, shoot dry weight, plant height and number of leaf blades. then the second best results were followed by goat manure and 1:1 soil which was best in increasing the number of tillers, root fresh weight, leaf fresh weight, root dry weight, crown fresh weight, canopy dry weight, number of leaves and height. plants. And giving goat manure by giving 2:1 has a good effect on the growth and yield of citronella plants. Keywords: Goat Manure, Soil, Growth, Yield, Fragrant Lemongrass

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

The impact of chemical pesticides in the long run can have side effects on the environment and human health. Neem leaf extract (Azadirachta indica juss) is an environmentally friendly solution in controlling kebul lice pests (Bemisia tabaci). This study aims to get an effect on the dose of neem leaf extract (Azadirachta indica juss) which has the potential to control whitefly infestation (Bemisia tabaci). This research was conducted using 4 treatments, in one treatment repeated 5 times with different doses. Each repetition contained 10 whitefly (Bemisia tabaci). The results showed that there was a significant effect on the administration of neem leaf extract (Azadirachta indica juss) in suppressing mortality of whitefly infestation (Bemisia tabaci). Neem leaf extract (Azadirachta indica juss) at a dose of 50 ml and 75 ml gives a good effect on whitefly (Bemisia tabaci) pests.The impact of chemical pesticides in the long run can have side effects on the environment and human health.

Abstract

Glutinous corn has a weakness in its production which is still low, especially in the Labuhanbatu area. This study aims to determine the growth and yield of maize pulut (Zea mays certaina L) from the administration of various doses of rice husk charcoal. This research was conducted in an experimental area in Ujung Batu Hamlet, Perbaungan Village, Bilah Hulu District, Labuhanbatu Regency, 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 M0: Ultisol soil without rice husk charcoal 10 kg, M1: (4 kg soil: 6 kg rice husk charcoal ), M2 : (5 kg soil : 5 kg rice husk charcoal) and M3 : (6 kg soil : 4 kg rice husk charcoal). Parameters observed were plant height, number of leaves, flowering age and cob weight. The data were analyzed using the F test with a confidence level of 5%. The results showed that the best treatment was to use the M2 treatment (5 kg soil: 5 kg rice husk charcoal). Keywords: corn, growth, rice husk charcoal

Abstract

Soil chemical properties have an important role in the growth and production of oil palm. Plants need nutrients to increase productivity. Oil palm (Elaeisguineensis Jacq) is the main plantation crop in Indonesia. This study aims to determine the characteristics of soil chemical properties in oil palm plantation stands of the people of Perlabian Village, South Labuhanbatu District, Kampung Rakyat District. The method used is a free grid survey method at the semi-detail survey level. Oil palm soil samples were taken from 6 oil palm sample trees with an area of 1 hectare. The parameters of the chemical properties of the soil are the content of N, P, K, Mg, pH, C-organic, and C/N. Data analysis was done by descriptive method. The results showed that the chemical properties of the soil in the people's garden of Perlabian Village, South Labuhanbatu Village, showed that the N-soil content was 0.14% (low), P-soil was 140.60 ppm (very high), K-soil was 0.08 me /100g (very low), Mg 0.09 me/100g (very low), pH level 5.00 (sour), C-organic content 3.48% (high), and C/N ratio 24.86 (high). Therefore, the chemical properties of the soil in the people's garden of Perlabian Village, South Labuhanbatu Village, still require proper fertilization to meet the needs of macro and micro nutrients in the soil.Keywords: Oil Palm, Chemical Properties, SoilKarakteristik Sifat Kimia Tanah Pada Tegakan Tanaman Kelapa Sawit (Studi Kasus di Kebun Milik Rakyat di Desa Perlabian Kecamatan Kampung Rakyat Kabupaten Labuhanbatu Selatan)

Abstract

Soil physical properties are the key determinants of the quality of a land and the environment. This study aims to analyze the physical properties of the soil in mature oil palm stands. The method used is a free grid survey method at the semi-detail survey level (observation density of 1 sample per 100 meters). Oil palm soil samples were taken from 6 oil palm sample trees in the people's garden of Perlabian Village, South Labuhanbatu Village, with an area of 1 hectare. The parameters of the physical properties of the soil tested were bulk density, soil porosity, soil color, and soil moisture content. Data analysis was done by descriptive method. The results showed that the physical properties of the soil in the community garden of Perlabian Village, South Labuhanbatu Village, showed good bulk density, clay and firmness, good soil porosity, relatively dark soil color, and high soil moisture content. Therefore, the physical properties of the soil in the people's garden of Perlabian Village, South Labuhanbatu Village are suitable for oil palm growth.. Keywords: Oil Palm, Properties, Physics, Soil

Abstract

South Labuhanbatu is a district in North Sumatra which is synonymous with a very large area of oil palm plantations. The area of oil palm plantations in South Labuhanbatu district is around 57,307 hectares with a total production of 640,196.60 tons. This study aims to determine the levels of nutrients uptake of nitrogen (N) in oil palm plants produce. So far, the status of testing for potassium nutrient uptake in people's plantations in Perlabian Village, Kampung Rakyat South Labuhanbatu District, has never been carried out. Fertilization and care are carried out through knowledge from generation to generation, so it is important to study the status of nitrogen uptake in oil palm leaves. This research was carried out using a semi-detailed free-level grid survey method with a density of 100 meters. A total of 6 leaf samples were taken on the 17th leaf midrib and then 70% alcohol was applied and put into a plastic sample for further testing in the laboratory of PT. Socfindo. The results showed that the 2nd leaf sample was deficient and 1, 3, 4, 5 and 6 leaf samples were at the optimum point. The uptake of N (nitrogen) in the leaves of oil palm plants in smallholder plantations in Perlabian Village, Kampung Rakyat District, showed that the total N content of leaves was included in the optimal category.Keywords: Nitrogen, Nutrient Uptake, Oil Palm Plants have
