2025-02-18T10:20:53+00:00

In this case, Coka Coffea producers have determined the right direction in producing Coka Coffea products which are enjoyed by coffee lovers in Central Kalimantan. This research aims to determine the income of Coka Coffea product producers as players in the roast bean coffee business with a distinctive taste and aroma, whose Liberica coffee is grown and harvested from the Sei Kemangkus area, Rungan District, Gunung Mas, Central Kalimantan. Post-harvest handling, often referred to as primary processing, is a term used for all treatment from harvest until the commodity can be consumed "fresh" or in preparation for subsequent processing. Post-harvest handling of coffee generally consists of: Pulping → Drying → Hulling → Defect sorting → Roasting → Fine grinding → Packaging → Marketing. The parameters looked at are aroma, color, water content, packaging and trademark, defective beans, coffee size, and marketing.

Analysis Of Biomass Of Mucuna Bracteata DC Due To The Provision Of Coffee Skin Waste As An Alternative Fertilizer

2025-02-18T11:42:29+00:00

Biomass Analysis of Mucuna bracteata DC Due to the Application of Coffee Husk Waste as an Organic Nutrient Source. Mucuna bracteata DC is a cover crop that plays a crucial role in soil conservation and soil fertility improvement. This study aims to analyze the effect of liquid organic fertilizer (LOF) derived from coffee husk waste on the biomass growth of Mucuna bracteata DC, particularly in terms of fresh shoot weight, fresh root weight, dry shoot weight, and dry root weight. The research was conducted at Jalan Kuali No. 50, Medan Petisah District. The experiment was designed using a Completely Randomized Block Design (CRBD) with a single-factor treatment consisting of seven LOF dosage levels: K0 (no treatment), K1 (5 mL/polybag), K2 (10 mL/polybag), K3 (15 mL/polybag), K4 (20 mL/polybag), K5 (25 mL/polybag), and K6 (30 mL/polybag), with four replications, totaling 28 experimental plots. The results showed that the application of coffee husk LOF significantly affected the biomass growth of Mucuna bracteata DC. The highest fresh shoot weight (9.51 g) and dry shoot weight (2.14 g) were recorded in treatment K6 (30 mL/polybag), whereas the highest fresh root weight (2.29 g) and dry root weight (0.32 g) were observed in treatment K5 (25 mL/polybag). Higher LOF doses generally increase plant biomass up to an optimal threshold, beyond which nutrient absorption efficiency by roots declines. Overall, the optimal LOF dosage for maximizing biomass growth in Mucuna bracteata DC ranges between 25–30 mL/polybag. The use of coffee husk waste as an organic nutrient source presents a sustainable alternative for improving plant productivity while reducing dependency on synthetic fertilizers.

2025-01-07T08:18:50+00:00

This research was carried out at the UPTD BIH Gedung Johor, Medan Johor, Medan City, starting from December 2023 to February 2024. This research aims to determine the effect of cucumber plant growth and production on the provision of potassium silica and cow manure. This research used a factorial randomized block design (RAK) with 2 treatment factors. The first factor is potassium silica with the symbol (K) which consists of 3 treatment levels, namely: Ko = Without potassium silica 0-gram polybag, Ki = 2.5 cc/ liter of water, K2 = 5 cc/ liter of water. The second factor is cow manure with the symbol (S) which consists of 4 treatment levels, namely: So = No fertilizer, S = 100 grams/polybag, S2 200 grams polybag, and S: = 300 grams/polybag. The parameters observed in this study were plant length (cm), number of leaves (strands), flowering age (days), number of fruit per plant (fruit), weight of fruit per plant (kg), number of fruit per plot (fruit), weight of fruit per plot (kg). The results of the research showed that Potassium Silica treatment had a significant effect on flowering age, and the number of fruit per plot, and had a very significant effect on fruit weight per plot. Providing cow manure fertilizer had no significant effect on all parameters. The best fruit weight per plot was obtained in the K0S2 combination, namely 2.13 kg.

The Effect Of Empty Fruit Bunch Composting Duration And Npk Fertilizer On Oil Palm Seedling Planting Media (Elaeis Guineensis Jacq) in Nursery

2024-11-04T04:28:20+00:00

The purpose of this study was to determine the growth of oil palm plants by giving empty bunch and NPK. This research was carried out in the people's garden in Binjai City, North Sumatra from January to April 2024. The research used a Factorial Randomized Group Design (RAK) with 2 treatment factors, the first factor of empty bunch consisted of 3 treatment levels, namely T0 = No empty bunch (Only Topsoil), T1 = 50% Topsoil and 50% empty bunch fermentation 2 Weeks, T2 = 50% Topsoil and 50% empty bunch fermentation 4 Weeks. The second factor is NPK with three treatment levels, namely N0 = 0 ml, N1 = 15 ml, and N2 = 25 ml. The parameters observed were stem diameter (mm), plant height (cm), leaf area (cm2), and number of leaves (strands). In this study, empty bunch treatment only had a significant effect on the growth of the number of leaves, and had no significant effect on the growth of stem diameter, plant height, and leaf area. NPK treatment only significantly affects the growth of stem diameter, but does not significantly affect the growth of plant height, leaf area, and number of leaves. The interaction between empty bunch and NPK treatments had no significant effect on the growth of stem diameter, plant height, leaf area, and number of leaves.

Effects of Liquid Sulfur Fertilizer and Azolla Application on the Growth and Yield of Bird’s Eye Chili (Capsicum frutescens L.)

2025-01-07T08:22:09+00:00

This research was carried out at the UPTD BIH Gedung Johor, Medan Johor, Medan City, starting from December 2023 to March 2024. This research aimed to determine the effect of applying liquid sulfur fertilizer and Azolla on the growth and production of cayenne pepper plants. This research used a factorial randomized block design (RAK) with 2 treatment factors. The first factor is liquid sulfur with the symbol (S) which consists of 3 treatment levels, namely: S0 = without sulfur fertilizer, S1 = 2.5 cc/liter of water, and S2 = 5 cc/liter of water. The second factor is Azolla with the symbol (A) which consists of 4 treatment levels, namely: A0 = Without Azolla, A1 = 20 grams/plant, A2 = 40 grams/plant, A3 = 60 grams/plant. The parameters observed in this study were plant height (cm), stem diameter (mm), flowering age (days), number of branches (branches), number of fruits per plant (fruit), fruit weight per plant (grams), number of per plot (fruit), fruit weight per plot. The results showed that liquid sulfur fertilizer treatment had no significant effect on all parameters. Giving Azolla had a significant effect on plant height at 2 WAP, 4 WAP, and some branches. The interaction between the two has no significant effect on all parameters. The best fruit weight per plant was obtained in the combination of S2A2 treatment (Liquid Sulfur 5 cc/liter of water + Azolla 40 grams/plant), namely 125.35 grams.

Growth Percentage And Length Of Mucuna Bracteata Tendles With The Provision Of Local Microorganisms (Mol) From Banana Corn

2024-07-19T08:54:19+00:00

Mucuna bracteata plants can be propagated in two ways: generatively and vegetatively. Vegetative propagation is done through cuttings, while generative propagation uses seeds. In 1999, Mucuna bracteata found it very difficult to produce flowers, fruits, and seeds. Due to this difficulty, propagation can be done through cuttings. This study uses a Non-Factorial Randomized Block Design (RBD) with 4 Treatments (P) and 6 Replications (U). The concentration of watering consists of 4 levels: P0 (0 ml), P1 (50 ml), P2 (150 ml), and P3 (250 ml). Meanwhile, the soaking duration also consists of 4 levels: P0 (0 minutes), P1 (5 minutes), P2 (10 minutes), and P3 (15 minutes). The results of the study showed that the interaction between the concentration of watering with MOL (Microorganism Local) from banana stems and the soaking duration did not have a significant effect on all parameters. Various concentrations of watering with MOL from banana stems and soaking duration significantly affected the growth of Mucuna bracteata. Although statistically, it did not show a significant effect, several treatment combinations could be observed, such as U6P3, which showed the highest root weight (15.44 grams). Then, the vine length was 117.1 cm, the number of leaves was 20, and the number of nodules was 11. As the highest values from P3, this shows the highest concentration of watering and soaking duration with MOL from banana stems. Thus, this effort can reduce agricultural waste and pathogens.
