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

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

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

Soursop is an annual plant that is rich in nutrients. The problem in soursop cultivation is that soursop has a hard seed coat, which causes the seeds to be impermeable to gases and air, inhibiting germination. Soursop seed dormancy can be broken by scarification and sulfuric acid immersion. This research aims to determine the effect of scarification position and sulfuric acid concentration on the viability of soursop seeds. The research used a completely randomized factorial pattern (CRD), which consisted of two factors with three replications. The first factor was the scarification position consisting of S0 (without scarification), S1 (base scarification), S2 (tip scarification) and S3 (middle scarification). The second factor was the sulfuric acid concentration consisting of K0 (control), K1 (10%), K2 (20%), and K3 (30%). The results showed an interaction between the treatment of scarification position and the concentration of sulfuric acid (c) on germination capacity and growth speed parameters. The combination of S0K1 (without scarification and 10% sulfuric acid) increased soursop seeds' germination and growth speed.

Abstract

Vegetables are usually classified by the part of the plant used for food, which is an essential source of many nutrients, including vitamins A and C, potassium, calcium, dietary fiber, and folate. Leafy greens are an abundant source of vitamin A and iron. The lack of fertile agricultural land has led to a decrease in the area of agricultural land, resulting in a decrease in the well-being of farmers. However, plant cultivation using the hydroponic method can be applied to solve this problem. Hydroponics is a method of growing crops without soil. Hydroponic farming is clean, simple, and efficient. This research aims to determine the effect of planting media type and AB mix concentration on hydroponic bok choy. The research used a Completely Randomized Design (CRD) with two factors and three replications, resulting in 27 experimental units. The first factor was planting media (M): Rockwool (M1), husk charcoal (M2), and sand (M3). The second factor was AB mix concentrations: 3 ml/l (K1), five ml/l (K2), and seven ml/l (K3).
