Abstract

Penelitian ini bertujuan untuk menentukan dosis abu sekam padi dan dosis pupuk kandang serta interaksi dosis yang optimal untuk pertumbuhan dan hasil bayam. Penelitian ini dilakukan di Mas Graha Village, Kabupaten Labuhanbatu yang berada pada ketinggian 26 meter diatas permukaan laut pada bulan agustus sampai bulan desember 2020. Penelitian menggunakan rancangan kelompok faktorial yang terdiri dari dua faktor. Faktor pertama abu sekam padi (A) terdiri dari 4 taraf, yaitu : A0 = 0 ton/ha (kontrol), A1 = 1 ton/ha setara dengan 50 g/m2 (dosis anjuran), A2 = 1,5 ton/ha setara dengan 75 g/m2. Faktor kedua yakni pemberian kotoran kambing (K) dengan tiga taraf yaitu : K0 = 0 ton/ha (kontrol) K1 = 2 ton/ha setara dengan 200 g/m2 (dosis anjuran), K2 = 4 ton/ha setara dengan 400 g/m2, K3 = 6 ton/ha setara dengan 600 g/m2. Adapun Parameter yang diukur adalah tinggi tanaman (cm), jumlah daun (helai) , berat per Tanaman Sampel (g). Hasil penelitian menunjukkan bahwa pemberian kotoran kambing 4 ton/ha setara dengan 400 g/m2 mampu meningkatkan tinggi tanaman, jumlah daun dan berat per tanaman bayam sedangkan aplikasi 1,5 ton/ha abu sekam padi setara dengan 75 g/m2 mampu meningkatkan tinggi tanaman, jumlah daun tanaman bayam Merah.

Abstract

Good seed growth is a factor in the success of oil palm cultivation due to genetic pre-nursery factors in the field, so that the provision of nutrients in the initial seed growth plays an important role in determining the overall appearance of the seedlings during its growing period. This study aims to determine the effect of oil palm seed growth by applying Uera fertilizer and rice husk charcoal organic fertilizer during the pre-nursery in the field. The experiment was carried out from October 2020 to May 2021 in the experimental garden of the Faculty of Science and Technology, Labuhanbatu University, Rantauprapat at an altitude of 13 meters above sea level. The experimental design in this study was a randomized block design with a factorial pattern that was repeated three times. The first factor is the dose of Uera fertilizer which consists of four levels, namely U0 = 0 kg / ha, U1 = 100 kg / ha, U2 = 200 kg / ha, U3 = 300 kg / ha and the second factor includes the dose of Rice Husk Charcoal Organic Fertilizer (ton / ha) consists of three levels, namely A0 = 0 ton / ha, A1 = 100 ton / ha, and A2 = 200 ton / ha. The results of the experiment showed that there was an interaction effect of uera fertilizer and rice husk charcoal organic fertilizer on plant height (cm),leaf area of ​​oil palm seedlings (cm2), in the number of leaves (leaf) and accretion hump diameter (mm). Treatment of urea fertilizer of 300 kg / ha and organic fertilizer of rice husk charcoal as much as 20 tons / ha produced plant height and leaf area during the pre-nursery

Abstract

Rubber plants (Hevea brasiliensis) will experience a decrease in production as plants age and the nutrient content in the soil decreases. This study aims to find out the chemical properties of soil on plantations of rubber crops that are converted into palm and coconut crops. The research was conducted from Februari 2023 to Agustus 2024 at the palm coconut plantation of PTPN III Aek Nabara North Garden in Labuhanbatu district and analyzed in the Land Laboratory of the Faculty of Agriculture of the University of Northern Sumatra. The methods used are observation methods, field sampling, and analysis in the laboratory to obtain quantitative data. Observation parameters include soil pH, C-organic, Total Nitrogen, Available P, Cation Interchange Capacity, and Base Fulness. The results of the survey showed that the level of soil fertility at the site of the research was included in the low category. The main limiting factor that causes the low fertility of the soil is the low content of organic material in the soil. In order to improve the fertility status of the ground at the research site for further planting, it is necessary to make efforts such as irrigation and fertilization, as well as the addition of organic materials, to make the availability of nutrients for plants more affordable. Keywords: replanting area, rubber plants, conversion, soil fertility, quantitative data

Abstract

This study entitled the provision of various organic materials on physical properties and ultisols in Pangkatan Sub-District Labuhan Batu Regency which was carried out in the experimental garden at the Labuhan Batu University campus, North Sumatra. This study aims to determine the best type of organic material to improve the physical properties of ultisol soil from the Rantau Selatan land at the Labuhan Batu. This study used a non-factorial randomized block design (RBD) with a treatment factor of 8 types of organic matter and 3 replications so that there were 27 experimental units. L0 Treatment: Control, L1: Palm oil solid waste, L2: Sugar factory waste, L3: Fish waste, L4: animal feed waste, L5: Chicken manure, L6: Cow manure, L7: Leguminose compost, L8: Compost organic waste fertilizer Medan city with a dose of each organic material 150g / 10 kg TKO. After incubation, bulk density (g /cm3) was taken using the Ring Sample method, Total Pore Space (%) with soil particle density and permeability (cm/hour) using the De Bootd method. Research Results Giving fish waste has the highest significant effect in improving soil physical properties such as reducing soil bulk density, namely 1.02 g / cm3, and increasing the total soil pore space by 61.63%, while the highest soil permeability is obtained in the treatment of animal feed waste, which is 60.22 cm. hour while the lowest was in the Control treatment of 29.11 cm/hour.
