Abstract

Coffee dregs biochar is an organic material that contains lots of nutrients for increasing soil fertility. The nutrient content in biochar is very good for plant growth. Research about the use of biochar from arabica coffee dregs (Coffea arabica L.) has been done to know its effectiveness in increasing the fertility of the planting medium. This research used a completely random design with a combination treatment consisting of 4 planting media mixtures. Treatment P 0 = Biochar: Compost coffee skin: Top Soil (0: 1: 2); P 1 = Biochar: Compost coffee skin: Top Soil (1: 1: 2); P 2 = Biochar: Compost coffee skin: Top Soil (1: 0: 2); P 3 = Biochar: Compost coffee skin: Top Soil (2: 1: 2); P4 = Biochar: Compost coffee skin: Top Soil (1: 2: 2); P5 = Biochar: Compost coffee skin: Top Soil (1: 1: 1). In the growth of Arabica coffee bud, treatment P1 showed best results at observation height plants (7.8 cm). Treatment P3 showed the best results at observation of total leaves (2.9). Treatment P1 showed the best results in the observation of leaves area (85.2 mm) and treatment P4 showed the best results in observing of stem diameter (2.4 mm). Treatment P1 also showed the best results for observation of wet weight (32.2 g) and dry weight (9.76 g). However, the control treatment showed best results on roots wet weight (7.41 g) and roots dry weight (2.07 g). Analysis results in nutrient content in processed coffee dregs biochar activated with coenzymes showed content element N: 1.45%; P: 223.45 mg; K: 3.54 mg; Ca: 21.78 mg; Mg: 2.56 mg. After the biochar is mixed with compost coffee skins and topsoil enhancement of nutrient content. Treatment combination is best shown by treatment P3 where element rate the highest elements N, P, K, Ca, and Mg compared to treatment other. Results showed that biochar combined in several types of planting medium is effective in increasing the fertility of the planting medium.

Abstract

This study discusses the acceleration of the growth of Arabica coffee biomass (Coffea arabica L.) in the pre-nursery phase through endophytic bacterial suspension immersion and application of coffee grounds biochar. The research was conducted in Hamlet 3 of Sampe Cita Village, Kutalimbaru, Deli Serdang, North Sumatra in March-May 2025. The method used was a factorial Group Random Design (RAK) with two factors, namely the soaking time of endophytic bacteria (0, 7, 8, and 9 hours) and the dose of coffee grounds biochar (0, 20, 40, and 60 grams). The results showed that the soaking treatment of endophytic bacteria suspension for 9 hours and the application of coffee grounds biochar gave the best results on the parameters of plant height growth and the number of Arabica coffee seedling leaves in the pre nursery phase. The combination of these two treatments provides a significant increase in biomass compared to other controls and treatments. In addition, the use of coffee grounds waste into biochar can be a waste management solution and reduce environmental pollution. The conclusion of this study is that the synergistic application of endophytic bacteria and biochar of coffee grounds is an environmentally friendly alternative to reduce the need for synthetic fertilizers in Arabica coffee cultivation while encouraging sustainable agricultural systems.

Abstract

The high demand for Arabica coffee (Coffea arabica [A1] L.) in North Sumatra must be accompanied by high productivity as well. One of the challenges often faced by coffee farmers is pest attacks. One way to address this issue is by conducting surveys on pest diversity and the intensity of pest attacks on coffee plantations. This study is a descriptive quantitative analysis with a cluster sampling method (sampling area) using yellow traps. The observation area covers 5 hectares, spread across 5 hamlets. Each hamlet consists of 5 plots, with each plot covering an area of 250 m². The observation period was divided into 4 sessions: morning, afternoon, evening, and night. The results of the observations showed that in Block 1, the total number of Diptera order was 105 individuals with a KR value of 77.5%, and the lowest order was Orthoptera with only 1 individual and a KR value of 3%. In Block 2, the order Diptera had 103 individuals with a KR value of 79.75%, and the lowest order was Odonata with 1 individual and a KR value of 2%. In Block 3, the most frequent order was Diptera with 57 individuals and a KR value of 68%, while the lowest order was Neuroptera with 1 individual and a KR value of 3%. In Block 4, the most frequent order was Hymenoptera with 59 individuals and a KR value of 39.5%, and the lowest order was Neuroptera with 1 individual and a KR value of 3%. In Block 5, the most frequent order was Diptera with a total of 60 individuals and a KR value of 65.5%, while the lowest order was Coleoptera with 1 individual and a KR value of 5%

Abstract

This study aims to determine the growth rate of Arabica coffee (Coffea arabica L) in the pre-nursery stage with the addition of chicken feather keratin fertilizer and blood serum. This study used a factorial randomized block design (RAK) with two factors, namely. The first factor is chicken feather keratin fertilizer with 4 treatment levels (0.5, 10, 15 gr.), while the second factor is the addition of blood serum with 4 treatment levels (0.15, 30, 45 ml / L). This study is expected to provide information about the effect of chicken feather keratin and blood serum on the growth of Arabica coffee seedlings, and can be a reference.

Abstract

highlights the need for innovation in nursery media based on locally available organic materials. This study aimed to analyze the effects of guano fertilizer and stalagmite sediment originating from Lawar Cave, Tangkahan, Langkat Regency, on the early growth of Arabica coffee seedlings (Coffea arabica L.). The research was conducted in Kutalimbaru District, Deli Serdang Regency, from May to July 2025 using a factorial Randomized Block Design (RBD) with two factors: guano fertilizer (0, 50, 100, and 150 g/polybag) and stalagmite sediment (0, 20, 30, and 40 g/polybag), with three replications. The observed parameters included plant height, number of leaves, leaf area, and root length. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test at the 5% significance level. The results showed that the interaction between guano fertilizer and stalagmite sediment had significant to highly significant effects on plant height and number of leaves. Application of guano at 50 g/polybag increased plant height by 1.38%, while stalagmite sediment at 30 g/polybag increased plant height by up to 2.97%. The highest number of leaves was obtained with guano at 150 g/polybag, showing an increase of 5.15%. Root length was significantly affected by stalagmite sediment, with an increase of up to 6.03%, whereas leaf area showed no significant differences among treatments. It can be concluded that the combination of guano fertilizer and stalagmite sediment effectively enhances the early growth of Arabica coffee seedlings and has strong potential to support sustainable coffee nursery systems.Research purposes.

Abstract

This study aims to determine the effect of auxin concentration (Rootone-F) and liquid organic fertilizer (POC) from lamtoro leaves (Leucaena leucocephala) on the growth of robusta coffee seedlings (Coffea canephora). The study was conducted in March–May 2025 in Sampe Cita Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra. The research method used a factorial Randomized Block Design (RAK) with two factors, namely the concentration of lamtoro leaf POC (M0=0 ml, M1=200 ml, M2=250 ml, M3=300 ml) and the concentration of Rootone-F (A0=0 ml, A1=200 ml, A2=250 ml, A3=300 ml), with three replications. The parameters observed included plant height, leaf area, number of leaves, and root length. The results showed that the administration of lamtoro leaf POC and Rootone-F significantly affected plant height, leaf area, and number of leaves of robusta coffee seedlings. The best treatment was obtained with a combination of 300 ml of lamtoro leaf POC and 250 ml of Rootone-F which resulted in optimal vegetative growth. Increasing the concentration of Rootone-F tended to decrease root length due to the biphasic effect of auxin on root growth. It can be concluded that the use of lamtoro leaf POC and Rootone-F at the right dosage can significantly increase the growth of robusta coffee seedlings.
