Abstract

Research on the application of billygoat weed, lantana, and cogon grass leaves extracts on anthracnose disease in chili plants. This research aims to determine the fungicidal activity of billygoat weed, lantana, and cogon grass leaves extracts on the growth and development of anthracnose disease in chili plants. This research method includes the extraction of billygoat weed, lantana, and cogon grass leaves, Potato Dextrose Agar (PDA) media preparation, Colletotrichum capsici fungal isolates breeding, and in vitro and in vivo testing. The research was conducted in the laboratory with three types of treatments arranged in a completely randomized design (CRD). The results of in vitro testing showed that billygoat weed, lantana, and cogon grass leaves extracts were able to inhibit the growth of Colletotrichum capsici colonies ranging from 0.50-1.24 cm, 80.58-92.15% inhibitory capacity, 0.16x1060.22x106 spore density at 7 days after inoculation and testing. The results of in vivo testing showed that billygoat, lantana, and cogon grass leaves extracts were able to reduce disease severity between 12.50-16.00%, disease incidence ranging from 26.00-30.00%, and chili fruit weight loss of 28.97-32.92%. Billygoat weed, lantana, and cogon grass leaves extracts have the potential as a botanical fungicide in controlling anthracnose disease in chili plants.

Abstract

Pomelo is a fruit commodity with high economic value and is in great demand by the public. Pomelo contains vitamins, proteins, and minerals the body needs to fulfill balanced nutrition. Aceh is one of the areas producing pomelo in Indonesia. The production of pamelo in Aceh is generally not optimal due to the limited supply of seeds that cannot be conventionally germinated. Plant tissue culture is one of the methods of propagation that can produce new plants in a relatively shorter time and large quantities. This research aims to determine the effect of natural and synthetic growth regulators on the growth of pomelo plants in vitro. The research used a factorial Randomized Block Design (RBD) of 2 factors. The first factor is the concentration of Benzyl Amino Purine (BAP) (0 mg/L, 1 mg/L, and 2 mg/L) and concentration of coconut water (0%, 15% and 30%).

Abstract

Potato is a horticultural plant that contains carbohydrates and nutrients. However, the problem faced in potato cultivation is the difficulty of obtaining high-quality tubers. Efforts that can be made to obtain healthy potato seeds are by propagating them using tissue culture techniques. The research aimed to determine the effect of the length of irradiation and application of BAP on the growth of granola potato micro cuttings in vitro. This research was conducted using a Split Plot Design (SPD) in a Completely Randomized Design (CRD) with two factors: length of irradiation (24-hour dark and 24-hour light) as the primary plot and BAP (0, 1, 2 mg/L) as sub-plots. Each treatment was performed in five replications. The results showed that the length of irradiation affected shoot growth time, number of roots (4-10 WAP), number of leaves (1-10 WAP), and shoot length (2-4 and 10 WAP). The best treatment was found in the 24-hour light treatment (L1). BAP treatment affected the percentage of growth success (9 and 10 WAP), root growth time, number of shoots (1, 4-10 WAP), number of roots (1-10 WAP), number of leaves (4-10 WAP), and shoot length (1-10 WAP).

Abstract

Durian (Durio zibethinus) is a Southeast Asian plant with a high nutritional content, delicious taste, and many good benefits. Durian has a high economic value with a wide and varied market range (traditional to modern markets). This shows that durian is a commodity with a lot of potential for development. The increase in production is inseparable from various problems in the cultivation aspect, especially in the provision of quality durian seeds. Durian plants are generally propagated vegetatively. Vegetative propagation of durian can be done by grafting. In durian grafting, various varieties are used as scion. These varieties have been known to have their respective advantages and markets. This research aims to determine the effect of three varieties of scion and grafting techniques on the success of durian grafting. The research used a factorial randomized block design (RBD) consisting of two factors, which are the scion varieties and grafting techniques. There are three varieties of scions, which are umpang duk (V1), monthong (V2) and bintan (V3). Meanwhile, the grafting technique consists of top grafting (T1) and side grafting (T2).

Abstract

Chili is included in horticultural commodities cultivated by Indonesian farmers. Red chilies are annual shrubs classified as vegetables the community needs as kitchen necessities. Expired seeds are seeds that have experienced a decline in growth and yield. Growth hormones can be used to increase the existing hormone levels and seed germination. Gibberellins are plant growth regulators that accelerate seed germination. Gibberellin is an essential organic compound in seed germination because it controls the process. The research was conducted to determine the effect of Gibberellins concentration and soaking time on the viability and vigor of expired red chili seeds. This research used a completely randomized design (CRD) with two factors. The first factor is the soaking time (P), which consists of 3 levels: 4 hours soaking (P1), 8 hours soaking (P2), and 12 hours soaking (P3). The second factor was the concentration of gibberellins (K), which consisted of 4 levels, which are 0 ppm (K0), 100 ppm (K1), 200 ppm (K2) and 300 ppm (K3).

Abstract

Lettuce (Lactuca sativa L.) is a plant whose leaves are consumed. The consumers of lettuce plants ranged from the lower to the upper-class societies. Fertilization is one of the technologies that need special care to increase the quality and quantity of the plant’s yields. Cow urine is one of the growth regulators that can be used. Not only it is easier to obtain, but also simpler the apply. Bagasse is a waste material that is usually thrown into an open place without further process, which can cause environmental disturbance and bad smell. This research aims to determine the effect of bagasse compost dosage and concentration of cow urine liquid on the growth and yield of lettuce plants. This research used a factorial randomized block design (RCBD) consisting of two factors. First, bassage compost (T) consisting of 0 g/polybag, 100 g/polybag, and 200 g/polybag, and second, cow urine liquid organic fertilizer (C) which also with three levels consisting of 0 ml/liter, 300 ml/liter, and 400 ml/liter of water. The results shows that 100 grams/polybag of bagasse compost and 300 ml/liter of cow urine liquid organic fertilizer each improve lettuce growth. Combined, they significantly enhance plant height, fresh weight, and dry weight.

Abstract

Orchids are very popular in Indonesia and the world as ornamental plants and floral arrangements. Therefore, orchids should be maintained and cultivated as they have high economic value. Orchids can be propagated by using seeds. Orchid seeds are tiny and do not have endosperm, making growing difficult. Efforts can be made to propagate this plant by using tissue culture methods. This study was conducted to determine the effect of MS media concentration and foliar fertilizer on the growth of Cymbidium orchid subcultures in vitro. The research method used a factorial randomized block design (RBD) of two factors. The first factor is the MS media concentration with three levels, which are M0 (full of MS), M1 (½ of MS), and M2 (¼ of MS). The second factor is the concentration of foliar fertilizer, which consists of three levels: P0 (0 g/L), P1 (1 g/L), and P2 (2 g/L).

Abstract

Pamelo (Citrus maxima (Burm.) Merr) is one type of orange that is prospectively cultivated in Indonesia. Pamelo in Indonesia is very diverse, as the skin of the fruit is green to red, some are  with seed and seedless. Pamelo plants have diverse leaves, both in shape, size, lamina and thickness. The various leaf shapes between plants which show below the genetic resources of pamelo plants are numerous and varied. Information about pamelo aceh plants, especially about the character of leaves is still very limited. This information can be used to determine the characteristics of pamelo aceh so that later it will be very useful in classifying and grouping plants. The purpose of this study was to determine the character of the Pamelo Giri Matang leaf in Aceh, Indonesia. The study aims to see the level of diversity of pamelo in the village of Pante Lhong. The study was conducted in the village of Pante Lhong, Peusangan District, Bireuen,  District, Aceh, Indonesia and at the Laboratory of Agroecotechnology, Faculty of Agriculture, Universitas Malikussaleh, from September to November 2017. The sample plants used were 15, aged between 10 and 25 years. The research was conducted using descriptive method with sampling by purposive sampling method. Observations were carried out quantitatively and qualitatively based on Descriptors for Citrus (PGRI). The results showed that Pamelo Giri Matang Aceh Indonesia was an evergreen plant with an intensity of green to dark leaf color. The average leaf lamina has a length of 14.62 cm and a width of 7.04 cm with an average area of 59.74 cm2. The most commonly found leaf wings are obovate.
