Abstract

This study aims to obtain the best combination dose of NPK 16-16-16 fertilizer and solid palm oil compost to support the growth of cocoa seedlings (Theobroma cacao L.) in polybag planting media. The study used a one-factor Completely Randomized Design (CRD) with a combination treatment design of NPK 16-16-16 fertilizer with solid palm oil compost (s) with 6 levels. 3 kg of ultisol soil/polybag as follows, s0 (3 kg of ultisol soil/polybag); s1 (100% NPK 16-16-16 (8g/polybag) ; s2 (100% solid palm oil compost (200g/polybag) ; s3 (75% NPK 16-16-16 (6g/polybag) + 25% solid palm oil compost (50g/polybag)) ; s4 (50% NPK 16-16-16 (4g/polybag) + 50% solid palm oil compost (100g/polybag) ; s5 (25% NPK 16-16-16 (2g/polybag) + 75% solid palm oil compost (150g/polybag). Based on the analysis of variance, it shows that the combination of NPK 16-16-16 fertilizer and solid palm oil compost has a significant effect on the parameters of plant height, leaf area, leaf color, dry weight of the crown, and the ratio of the root crown but has no significant effect on the stem diameter, weight dry roots, and cocoa seedling quality index. Treatment s2 (100% solid compost 200g) gave the highest average value for all observation parameters

Abstract

Oil palm is a strategic plantation commodity that plays a vital role in Indonesia’s economy as a major contributor to non-oil and gas revenue. Its high productivity and market value make it an attractive investment. However, basal stem rot (BSR) caused by Ganoderma sp. remains a major constraint in plantation management. This study aims to compare the incidence and severity of the disease between oil palms derived from improved and non-improved seeds. The research was conducted from August to November 2024 in Suban Village, Batang Asam District, Tanjung Jabung Barat Regency using an unformatted trial design with purposive site selection. Data were collected through field symptom observations, farmer interviews, and environmental factor measurements, then analyzed qualitatively (data tabulation) and quantitatively (paired t-test). The results revealed that palms from improved seeds showed a disease incidence of 2.96% with 2.14% severity, while non-improved seeds exhibited 3.33% incidence with 1.85% severity. These findings indicate that improved seeds are relatively more resistant to Ganoderma sp. infection, although the disease severity tends to be slightly higher. This study provides important insights for disease management strategies and serves as a reference for farmers in selecting seed sources to optimize oil palm productivity.

Abstract

Coffee is one of the plantation commodities that plays a fairly important role in economic activities. One type is robusta coffee, which until now is the type of coffee that dominates coffee plantations in Indonesia. One of the planting media that can be used for robusta coffee nursery activities is ultisol soil. The problem of low fertility in ultisol soil can inhibit seedling growth. The addition of humic acid is needed to improve soil structure and fertility, and can help in the absorption of nutrients needed by plants. This study aims to obtain the best dose of humic acid to support the growth of robusta coffee seedlings in ultisol planting media. This study was carried out for 3 months starting from May - August 2024. This research was conducted on Jl. Rajawali, Kenali Besar, Kec. Kota Baru, Jambi City. The environmental design used in this study was a Completely Randomized Design (CRD) with one treatment factor, namely humic acid (g polybag-1) consisting of 6 different treatments, namely a0 (control), a1 (5 g), a2 (10 g), a3 (15 g), a4 (20 g), a5 (25 g). Each treatment was repeated 4 times, so that 24 experimental units were obtained. Each experimental unit consisted of 4 plants consisting of 3 sample plants and 1 reserve plant, so that the total was 96 plants. The results showed that humic acid treatment had a significant effect on stem diameter, total leaf area, dry weight of the crown, dry weight of the roots, water content of the media, and the quality index of robusta coffee seedlings. However, this treatment had no significant effect on plant height and number of leaves of robusta coffee seedlings on ultisol planting media. The administration of humic acid in treatment a3 (15 g) can increase the growth of stem diameter by 5.16%, dry weight of the crown by 7.56%, dry weight of the roots by 21.05%, and seedling quality index by 6.57%, compared to without treatment (control).
