Abstract

Areca nut (Areca catechu L.) is one of the leading plantation commodities in Jambi Province which has high economic value and plays an important role as a source of foreign exchange for the country. Areca nut plants in Jambi Province are most widely located in Betara District, West Tanjung Jabung Regency. To increase the yield of areca nut, it is necessary to know the diseases that attack areca nut and the percentage of the disease attack. It is useful for disease control in areca nut. This study aims to find out about the main diseases that attack areca nut plants such as yellowing leaf spot, leaf blight, leaf red rust, root rot/base of stem, fruit rot, shoot rot, yellow leaves, foot rot, flower die back and fruit drop, and Bacterial leaf stripe.  The research was conducted using the Simple Random Sampling method. Plant samples were taken randomly at the people's areca nut plantations in Mandala Jaya Village, Betara District. Observations were made by looking at the symptoms of the disease and calculating the percentage of plants affected by the disease. Samples of areca nut plant parts that were attacked by the disease were identified at the Unbari Basic Laboratory.The research that has been conducted in Mandala Jaya Village, Betara District, Tanjung Jabung Barat Regency, it can be concluded that three main diseases were found in areca nut, namely yellowing leaf spot caused by the fungus Curvularia sp, leaf blight disease caused by the Pestalotia palmarum fungus and red rust leaf disease caused by the fungus Cephaleuros sp.  The percentage of disease attacks, namely, yellow leaf spot disease (Curvularia sp.) was highest on P1 land by 40%, the highest percentage of Leaft Blight disease was found in P1 area at 35% and the highest percentage of red rust leaf disease was found in P1 area, which was 20%.

Abstract

The purpose of this study was to determine the growth of cocoa seedlings on Ultisol soil treated with cow dung compost. This research was conducted in the piyo garden, Batanghar University, Jambi Campus II. The environmental design used was a completely randomized design (CRD) and the treatment design was cow dung compost which consisted of 4 treatments: K0 = no treatment (control), K1 = 100 gr/polybag of cow dung, K2 = 150 gr/polybag of cow dung, K3 = 200 gr/poly bag of cow dung. Observational data were analyzed using analysis of variance, if there was a significant effect it was followed up with Duncan's Multiple Range Test (DNMRT) at the 5% level. The results showed that the application of cow dung compost at different doses had a significant effect on plant height and stem diameter and had no significant effect on plant dry weight and root dry weight. Cocoa plant height increased by 36.64% and stem diameter by 18.26% with K3 treatment compared to the amount without treatmentKeywords: cow dung compost, Ultisol and cocoa

Abstract

Acid sulfate soils are quite abundant in Indonesia, and some have been used for agricultural land. The main problem with this soil is the presence of pyrite compounds (FeS2). The oxidation of these compounds causes the soil to become acidic, metals and bases dissolve so that the soil becomes poor and the life of aquatic biota affected by the drainage water is disturbed. The oxidized soil, if flooded again, causes an increase in ferrous iron ions and hydrogen sulfide which can poison plants, therefore management of acid sulfate soils needs to be carried out so that the soil has characteristics that can support plant growth. Some soil management actions that can be taken are controlling the activity of microorganisms in the oxidation and reduction processes of pyrite, providing amelioration materials and fertilization, land management and water management.
