Abstract

The Response Of Liquid Waste Utilization Of Palm Oil On Growth And Production Plant Of Kailan (Brassica Oleraceae L.). Under the guidance of  Ir. Gusmeizal, MP as the commission chairman of counselor and Ir. Ellen L. Panggabean, MP as the commission member of counselor.  This research was conducted at the experimental garden of Agriculture Faculty University of Medan Area, located on Jl. PBSI Medan Estate. This research was conducted began in April 2016 until June 2016. The purpose of this research was to determine the response of liquid waste utilization of palm oil on growth and production plant of kailan. This research was conducted by using Randomized Block Design (RBD) non factorial which consists of 4 levels of treatment are: L0 = Control (NPK 20 g/plot),  L1 = 1 l/plot,  L2 = 2 l/plot,  L3 = 3 l/plot. Parameters observed were height of plants, leaf number, stem diameter, fresh weight of harvest by plot, fresh weight of harvest by sample, fresh weight of sell by plot, fresh weight of sell by sample. The results of research showed that utilization of liquid waste of palm oil did not show significantly different results in all parameters of observation, but the liquid fertilizer from palm oil waste is able to compensate for the growth and production plant of kailan (Brassica oleracea L.) that fertilized with NPK.

Abstract

Pakcoy crop (Brassica rapa L.) is included in the type of vegetable mustard which is quite economical. Today, pakcoy crop used by the community in various cuisines. This crop is quite easy to cultivate and only takes a short time of about 3 to 4 weeks. The purpose of this study to obtain data on the growth response and production of pakcoy crops on the application of organic fertilizer chicken manure and organic fertilizer cow urine liquid and can be a combination between the two treatments. This research was conducted at the Experimental Farm Faculty of Agriculture, University Medan Area, Kolam street No. 1 Medan Estate districts Percut Sei Tuan with a height of 20 meters above sea level (asl) in the months of October to December 2016. This research has been done by using factorial randomized block design consisting of two factor. The first factor treatment which tested is organic fertilizer chicken manure is A0= Control (without organic fertilizer chicken manure); A1= fertilizer chicken manure 1 kg/m2; A2= fertilizer chicken manure 2 kg/m2 dan A3= fertilizer chicken manure 3 kg/m2. The second factor tested is POC concentration of cow urine is : S0= Control (without cow urine); S1= 30 ml urin sapi / L of water ; S2= 60 ml urin sapi / L of water dan S3= 90 ml urin sapi / L of water. The results showed that organic fertilizer chicken manure treatment had significant effect on the parameters of plant height from age 2 MST to 4 MST  wet weight per sample. the best treatment is A3 (3kg/plot).

Abstract

This study aims to determine the index of diversity and abundance of insects in red chili with refugia flower kotokan (Tagetes erecta L.) The method used in this study was descriptive analysis using ordinal sampling using a non-factorial randomized block design. This research was carried out in the experimental garden of the Faculty of Agriculture, Medan Area University, from April to June 2021. The insect traps used were yellow sticky traps, pitfall traps, and sweep nets. The results showed an abundance of 2,972 insects consisting of 11 insect orders, 34 insect families and 39 species. Insects from the family Tettigoniidae had the highest value of 10.53%. While the value of predatory insects is 5.15%. from the family Formicidae. The value of the diversity index in the red chili plant area with Tagetes erecta L was (H') 3.3045 (height). The value of the evenness index of insect species (E') in the area of red chili with refugia was 0.902 (quite abundant).

Abstract

The Waste Utilization Of Jengkol Peel As Raw Material Compost And Biochar In Increasing Growth And Production Of Onion (Allium Ascalonicum L.). Guided by Dr.Ir. Sumihar Hutapea, MS and Ir.H.Abdul Rahman, MS. This research aimed to determine effect of giving compost jengkol peel on the growth and production of onion, effect of giving biochar jengkol peel on the growth and production of onion, and effect of the combination between compost and biochar waste of jengkol peel on the growth and production of onion (Allium ascalonicum L.). This research was conducted in the House Kasa Growth Centre Kopertis Region I North Sumateta-Nanggroe Aceh Darussalam from April until September 2016. The research was conducted by planting in polybags with soil weight 5 kg/polybag. This research was conducted by using Randomized Block Design (RBD) factorial with 2 factors treatment. The first factor is compost of jengkol peel that consists of 4 levels dose are : K0 = (control), K1 = (10 ton/ha or 25 g/polybag), K2 = (20 ton/ha or 50 g/polybag), K3 = (30 ton/ha or 75 g polybag). The second factor is biochar of jengkol peel that consists of 4 levels dose are : B0 = (control), B1 = (5 ton / ha or 12.5 g / polybag), B2 = (10 ton / ha or 25 g / polybag), B3 = (15 ton / ha or 37.5 g / polybag). The results of research showed that treatment of jengkol peel compost was very significant effect on plant height at of 2 and 3 MST observation, significant effect on the observation aged 4 and 5 MST, and it is not affected real to the age of 6 MST observation. To the observations on the number of leaves on the age of 2, 3 and 4 MST is very significant effect, significant effect on the age of 5 MST observation and not affected real on the age of 6 MST observation. On the number of cloves and tuber diameter is not affected real. Fresh weight of tuber and dry weight of tuber is significant effect. Treatment of jengkol peel biochar is not affected real on all parameters of observation. Interaction treatment of compost and biochar of jengkol peel is significant effect on leaf length 2 and 3 MST, number of leaf age 2 MST and it is not affected real on other parameters.

Abstract

This study aims to determine the response of growth and production of sweet corn plants to the application of modified SP-50 biochar and plant growth promoting rhizobacteria (PGPR). The design used was Factorial RAK which consisted of 2 treatment factors, namely: (1) Biochar SP-50 (B)     consisted of 3 levels, B0 = Without Biochar, B1 = Dose 10 tons/ha, B2 = dose 20 tons/ha. (2) PGPR (P) consists of 4 levels, treatment P0 = No PGPR, P1 = PGPR concentration of 1%, P2 = PGPR concentration of 2%, P3 = PGPR concentration of 3%. The results of this study showed that the application of Biochar SP-50 had a significant effect on stem diameter, number of leaves, weight of cobs with cocob per plot, weight of cobs without cob per plot, and a very significant effect on the number of seed rows. The best treatment is giving SP-50 biochar as much as 20 tons/ha. The provision of PGPR did not significantly affect the growth and production of sweet corn plants but gave a positive effect with the best concentrations of 1% and 3%. The combination of Biochar SP-50 and PGPR had a significant effect on plant height, cob weight with cob per sample and cob weight without cob per sample. The best treatment was giving Biochar SP-50 at a dose of 20 tons/ha and PGPR with a concentration of 3%.
