Abstract

Cocoa is a type of tree that originates from South America and is now widely cultivated in other countries, including Indonesia. In certain areas in Indonesia, quality land has begun to decrease. An alternative that can be utilized is the use of Red Yellow Podsolic (PMK) soil to plant cocoa. One effort to increase soil productivity and increase the organic matter content in PMK soil is by adding coconut pulp compost as an alternative to inorganic fertilizers. This study aims to determine the effect of giving coconut pulp compost on the growth of cocoa seedlings and what is the best dose of coconut pulp compost that affects the growth of cocoa seedlings in PMK media. This study used a non-factorial Completely Randomized Design (CRD) with 5 treatments and 5 replications. Each treatment consisted of 3 samples so that 75 plant samples were obtained. The treatments were: B0: without coconut pulp compost (0 g/polybag), B1: coconut pulp compost dose of 200 g/polybag, B2: coconut pulp compost 250 g/polybag, B3: coconut pulp compost 300 g/polybag, B4: coconut pulp compost 350 g/polybag. The data obtained were analyzed using Analysis of Variance (ANOVA) and further tested by Duncan's Multiple Range Test (DMRT) at the 5% level. Based on the analysis of variance, the provision of coconut pulp compost had a significant effect on seedling height (20.60 cm), dry weight of the shoot (1.61 g), and dry weight of the roots (0.41 g) which could increase the growth of cocoa seedlings. The best treatment was the provision of coconut pulp compost dose of 350 (g/polybag).

Abstract

Coffee cultivation cannot be separated from the seeding media, one of which is the media, one of which is peat which is widespread in Indonesia, the limited nutrient elements of peat are overcome by providing bamboo leaf compost, containing 1.35% N, 3.47% P, 0.37% K. The research aims to determine the effect of providing bamboo leaf compost on the growth of robusta coffee seedlings in peat soil. The research was conducted at the Sungai Awan Kiri Village Experimental Garden, Muara Pawan District, from March to June 2024. The research used a completely randomized design (CRD) consisting of 5 treatments and 5 replications, there were 25 experimental units, each experiment consisted of 3 samples so that the total number was 75 samples. . The parameters observed were plant height, stem diameter, number of leaves, root length and wet weight. The data was analyzed statistically using Analysis of Variance (ANOVA), if what was found had a real effect, then continued with the Duncan Multi Range Test (DMRT) at the 5% level. The results showed that the application of bamboo leaf compost had a real influence on the growth of Robusta coffee seedlings on plant height, stem diameter, number of leaves, root length and plant fresh weight. A dose of bamboo leaf compost of 450 g/polybag was the best treatment to increase the growth of robusta coffee seedlings with an average seedling height of 10.35 cm, stem diameter of 2.73 mm, number of leaves of 9.47, root length of 12.62 cm and plant wet weight of 2.59 g.

Abstract

Coffee is one of the mainstay commodities in the Indonesian plantation sector. To encourage plant growth and improve the quality of coffee plants, Photosynthetic Bacteria (PSB) are applied, which are autotrophic bacteria that can photosynthesize. Providing PSB to the soil can help increase soil fertility, accelerate plant growth, physiologically active compounds and polysaccharides. The purpose of this study was to determine the effect and best concentration of Photosynthetic Bacteria (PSB) on the growth of robusta coffee plants (Coffea canephora) in Ultisol soil. This study used a non-factorial Completely Randomized Design (CRD), consisting of 5 treatments and 5 replications so that there were 25 experimental units, where each experimental unit consisted of 3 seed samples so that the total number was 75 seed samples. The treatments were P0: soil media without PSB, P1: Concentration 25 ml/L P2: Concentration 50 ml/L, P3: Concentration 75 ml/L, P4: Concentration 100 ml/L. The data obtained were analyzed statistically using Analysis of Variances (ANOVA). If there is a significant effect, it will be continued with Duncan's Multiple Range Test (DMRT) at the 5% level. The results showed that the provision of Photosynthetic Bacteria (PSB) had a significant effect in increasing the growth of robusta coffee plants (Coffea canephora) in ultisol soil media on soil pH parameters, plant height, stem diameter, number of leaves, root length, and dry weight of plants. The best concentration of Photosynthetic Bacteria (PSB) administration on the growth of robusta coffee plants (Coffea canephora) aged 12 MST in the P2 treatment was a concentration of 50 ml/L with a soil pH of 6.02, plant height of 12.88 cm, stem diameter of 1.41 mm, number of leaves 6 strands, root length 12.07 cm and dry weight 0.35 g.

Abstract

Wastewater from catfish farming comes from leftover feed and feces that contain organic and inorganic materials. The wastewater from catfish farming has an organic C content of 0.06-0.62%; N 0.49-1.32%; F 0.06-0.35%; K 0.22-4.97% and pH 5.67-8.00. This study aims to determine the effect of liquid organic fertilizer (POC) from catfish farming waste on the growth of rubber seedlings and to identify the effective concentration of POC that influences the growth of rubber seedlings. The study used a completely randomized design (CRD) non-factorial consisting of 5 treatments and 5 replications for a total of 25 experimental units, with each unit containing 3 samples, resulting in a total of 75 samples. The treatments were L0: 0 mL L-1, L1: 150 mL L-1, L2: 250 mL L-1, L3: 350 mL L-1, L4: 450 mL L-1. The results showed that a concentration of 150 mL L-1 was able to enhance stem diameter, and a concentration of 250 mL L-1 was able to increase plant height. A concentration of 350 mL L-1 is able to increase the number of umbrellas and the wet weight of the seedlings, and the dry weight of rubber seedlings will increase when given POC with a concentration of 450 mL L-1.

Abstract

The productivity of rubber plants in Indonesia is relatively low, so efforts to increase productivity need to be made, one of which is by improving cultivation technology, the limitation of nutrients in the soil of former gold mines is overcome by providing vegetable waste compost. Vegetable waste compost has a C-organic content of 28.89%, N 1.57%, P 1.39%, K 0.69%. This study aims to determine the effect of vegetable waste compost on the growth of rubber seedlings on the soil of former gold mining land. The research was conducted at the Sukaharja Experiment Garden, Gg. Pandan, from April to July 2024. The study used a non-factorial Complete Random Design (RAL) consisting of 5 groups and 5 replicates, there were 25 experimental units, each experiment consisted of 3 samples so that the total number of samples was 75 samples. The parameters observed were the height of the seedlings, the diameter of the stems, the number of umbrellas, and the dry weight of the seedlings. The data is statistically analyzed with Analysis of Variance (ANOVA), if obtained has a real effect, then the Duncan Multi Range Test (DMRT) is continued at the level of 5%. The results of the fingerprint showed that the treatment of vegetable waste composting had a real influence on the variables of seedling height, stem diameter, number of umbrellas, and root volume. The results of the DMRT test at 5% level show that treatment with a dose of vegetable waste compost of 640 g/polybag is able to provide good growth for the growth of rubber seedlings.
