Abstract

Watering is a method that used to fulfill the water needs of oil palm seedlings in the nursery. In watering that must be considered is the quality and amount of water given and the right watering time. The aim of this research was conducted the Influence of frequency of watering to several types of seeds of high oil palm (Elaeis quineensis Jacq.) that thick mesocarp in the Main Nursery 4 until 7 month. The research was conducted at the Faculty of Agriculture, Universitas Sumatera Utara, Medan (± 32 meters above sea level), which began from September to November 2017. This Research was conducted by using a Factorial Randomized Complete Design with two factors. The first factor is watering consists of in the morning (1 time) and in the morning & evening (2 times), the  second  factor is varieties of oil palm that thick mesocarp consists of Avros, Simalungun and PPKS 540. The observation parameters is the total leaf area. The results showed that frequency treatment of watering is not significant but the varieties of oil palm that thick mesocarp significanly different Avros to Simalungun and PPKS 540 and interaction both had no significant effect on the growth of oil palm seedlings.

Abstract

The low productivity of soybean in Indonesia was caused by natural factors, biotics, cultivation techniques and soybean plant physiology. Extensification program to meet the needs of soybeans can be solved by using dry land, of drought stress. The study was conducted at the Screen house Faculty of Agriculture, Universitas Sumatera Utara, Medan (± 32 meters above sea level), on July to October 2017, using a randomized block design with 2 treatment factors. The first factor is drought stress with 3 levels ie 80% ; 60% and 40% field of capacity(FC) . The second factor is an ascorbic acid with 4 levels of concentration ie: 0 ; 100 ; 200 and 300 ppm.. The observed of variables ie number of leaves, total leaf area, dry seed weight per plant, 100 seed weight and harvest index. The results showed that the increased treatment of drought stress (80 – 40% FC) had the significant on all observed variables. The Ascorbic acid treatment no significant on all observed variable with the average number of leaves and the highest total leaf area at use 200 ppm ascorbic acid and the lowest at control treatment. The interaction no significant on all observed variable.

Abstract

Sweet corn is a crop has a very good nutrient and tastes sweet and Calsium influenced contain. Ultisol is one of the soil that spreaded vastly in Indonesia, up to 25% of Indonesian total terrestrial area. Ultisol is an acidic soil, hence clacification can be applied to deal with it. The purpose of this research was to determine the growth response of sweet corn in two sources of calcium nutrients application to Ultisol soil. This research was conducted in the gauze of the Faculty of Agriculture, University of Sumatera Utara with an altitude of ± 32 m above sea level starting from October 2017 to December 2017. This research used a Non Factorial Completely Randomized Design with 7 treatments and 4 repetition, the treatment of which was calcium nutrient, shell egg (9.22 g / 15 kg soil), eggshell (13.84 g / 15 kg soil), eggshell (18.45 g / 15 kg soil), dolomite 1 x Aldd (equivalent to 9.22 g / 15 kg of soil), dolomite 1.5 x Aldd (equivalent to 13.84 g / 15 kg of soil), dolomite 2 x Aldd (equivalent to 18.45 g / 15 kg of soil). The results showed that the two sources of calcium nutrients (eggshell or dolomite) applications had no significant effect on plant height, leaf number, stem diameter, canopy and root wet weight, and canopy and root dry weight.

Abstract

Based on Spatial Planning Law No. 26 of 2007 concerning Spatial Planning, Article 29 states that the proportion of public green open space is 20% of the city area. In Tebing Tinggi City, based on the 2013-2033 RTRW of Tebing Tinggi City, it is stated that Public RTH covers an area of ​​approximately 72.49 Ha or 1.89% of the city area, which means it is not in accordance with the mandate of Spatial Planning Law No. 26 2007 concerning Spatial Planning. This research was conducted to assess the availability of existing public green open space in Tebing Tinggi City based on image interpretation techniques, spatial distribution, the area of ​​existing public green open space, the service radius of existing public green open space, and the suitability of existing public green open space land. This type of research uses quantitative research and uses spatial analysis techniques. The results identified as many as 60 public green open spaces in Tebing Tinggi City with an accuracy score of 86.36%, which means that the interpretation is considered correct because the spatial distribution pattern of public green open spaces in Tebing Tinggi City is random because the distribution of public green open spaces is not evenly distributed in all sub-districts in Tebing Tinggi City. From the results of the spatial distribution pattern, digitization was then carried out with the result that the total public open space area was 105.27 Ha, which was dominated by the burial area of ​​59.67 Ha or 57.07%. Then, based on each area of ​​green open space obtained, a topological classification of public green open space is carried out, consisting of 7 typologies of green open space, namely City Forest, City Park, District Park, Village Park, RW Park, RT Park, Cemetery and Green Belt, which is then analyzed. Service radius. As a result, it is known that the City of Tebing Tinggi has not been served optimally by public green open space because there is not yet one type of public green open space typology that is capable of serving the city of Tebing Tinggi based on buffer analysis carried out using ArcGis. The only public green open space whose service radius almost covers the city of Tebing Tinggi is the cemetery whose existing existence is capable of serving 99.19 percent of the area of ​​the city of Tebing Tinggi. Finally, a land suitability analysis was carried out between the existing public green open space and the Tebing Tinggi City RTRW for 2013-2033 which resulted in land suitability of 79.92%. Meanwhile, the remaining 20.08% was designated for areas that were not public green open space.

Abstract

Bananas are one of the climacteric fruits Ethylene is a hormone that play a role in the fruit ripening process during the climacteric phase, to accelerate the ripening process of fruit, to be utilized as a stimulant latex for rubber plants. This study aims to utilize banana peel waste (Musa paradisiaca L.) as a source of ethylene. This study used a completely randomized design (CRD) non-factorial that is, green banana skin with ripening 0, 1, 2, 3 days, yellowish green banana peel with ripening 0, 1, 2, 3 days, yellow banana skin with ripening 0, 1,2,3 days. This research was conducted by titration method which was repeated three times. The results showed that the highest ethylene content was found in yellow banana peels with 1 day ripening. Keywords: ethylene, banana peel color, ripening time

Abstract

Growth response of cacao seedlings (Theobroma cacao L) on foliar fertilizer application and the right frequency of water application is done so that the needs of nutrients and water are met for cacao seedlings in the nursery. This study aims to analyze the growth of cocoa seedlings (Theobroma cacao L) on foliar fertilizer application and frequency of water application. This research uses a Factorial Randomized Block Design with 2 treatment factors. Factor I: Foliar fertilizer dosage (ml/l water): 0, 4, 6, and 8 and factor II: Frequency of water application: 1, 3, 5 and 7 days. The parameters observed are plant height, stem diameter, number of leaves, total leaf area, leaf thickness, crown dry weight, root dry weight. The results showed that the application of foliar fertilizer at a dose of 8 ml/l water gave the best growth response with significant effect on all observed variables of cocoa seedling growth. Frequency of water application under field capacity conditions has a significant effect on total leaf area and leaf thickness with 1x/day water application. The interaction of the two treatments has no significant effect on all observed variables. Keywords: cocoa seedlings, foliar fertilizer, watering interval
