Abstract

Cocoa (Theobroma cacao L.) is a plantation commodity that is widely cultivated in Indonesia, this commodity is very important in Indonesia because it has played a role in the Indonesian economy since 1930. The problem faced in cocoa cultivation is the lack of nutrient availability due to chemicals that cause residue in the soil, resulting in the growth of cocoa seedlings are not optimal, to optimize the growth of cocoa seedlings, provide a mixture of organic fertilizer in the planting medium and provide mycorrhiza. This research used the basic pattern of a factorial Completely Randomized Design (CRD) consisting of 2 factors and repeated 3 times. The first factor is the dose of dry leaf compost (K) which consists of 3 levels, namely: Without dry leaf compost treatment/control (K₀), dry leaf compost 60 g/polybag (K₁), Dry leaf compost dose 120 g/polybag (K₂) and the second factor is the arbuscular mycorrhizal dose (M) which consists of 3 levels, namely: Without arbuscular mycorrhizal fungus treatment/control (M₀), arbuscular mycorrhizal dose of 15 g/polybag (M₁), and arbuscular mycorrhizal dose of 30 g/polybag (M₂) So there are 27 experimental units. The results of the study showed that (1) there was a real interaction between the treatment of compost dose (K) and mycorrhizal dose (M) in safety. The combination of compost dose (K) 120 g/plant and mycorrhiza dose (M) 30 g/plant (K2M2) was the best treatment combination. (2) The treatment of giving a compost dose (K) had a significant effect on the variables of plant height, number of leaves, stem diameter, and plant dry weight. The best treatment was a compost dose of 120g/plant (K2). (3) The mycorrhizal dose (M) treatment had a very significant effect on the variables of plant height, number of leaves, stem diameter, and plant dry weight. The best treatment was a mycorrhizal dose of 30g/plant (M2).

Abstract

Bondowoso Arabica coffee is a type of coffee that grows on the slopes of Mount Ijen-Raung. It has a high commercial value and distinctive taste. Coffee processing applications from roasting, grinding, packaging and brewing to storage will affect the quality of coffee. Caffeine is one of the compounds in coffee that contributes to bitterness and has certain pharmacological effects. This study aimed to determine the caffeine content of Bondowoso Arabica coffee harvested on August 2021 which was obtained from Sukosari Lor village with various roast profiles and types of packaging. In this study, Arabica coffee was roasted with light roast, medium roast and dark roast profiles. Then each treatment was mashed to obtain ground coffee. Ground coffee was put in a standing pouch made of polyethylene terephthalate (PET) with a thickness of 75 microns; polypropylene (PP) with a thickness of 100 microns; and polypropylene (PP) with a thickness of 120 microns and then stored for three months. During the storage of first and third months, caffeine levels were measured. Based on the results of the study, the caffeine content was increase along with higher roasting temperature. During the storage process, the caffeine content in ground coffee packaged using PP decreased the most.

Abstract

Cocoa (Theobroma Cacao L.) as a plantation crop which success is determined by healthy and quality seedlings. The use of planting media with a mixture of manure and plant organic supplements may result in healthy soil because it contains soil microorganisms that are beneficial and may support the growth of cocoa seedlings. Purpose of this study was to determine the initial growth response of cocoa seedlings on various growing media and dosages of an organic plant supplement as liquid organic fertilizer. The research was conducted in February–September 2022 in a nursery located in Kradenan, Purwoharjo, Banyuwangi Regency and in Agricultural Laboratory of University of Jember, Bondowoso Campus, Bondowoso Regency. Study was carried out in a 4 x 4 factorial using a randomized block design with three replications. The first factor was planting media which consisted of four levels of treatment, namely soil + chicken manure, soil + goat manure, soil + cow manure, and soil + rabbit manure. The second factor was dose of organic plant supplement which consisted of 4 levels, namely the control treatment of 0, 50, 100, and 150 mL polybag-1. Data were analyzed using analysis of variance and follow-up tests using Duncan’s multiple range test at 5% level. Variables observed included seedling height, number of leaves, stem diameter, leaf length, leaf width, number of roots, root length, fresh weight, and dry weight of seedlings. The results showed that there was an interaction effect on all parameters except seedling height, number of leaves, and number of roots. The conclusion of the study showed that there was an effect of interaction treatment with the best treatment combination planting media using cow manure and organic plant supplement dose of 50 mL polybag-1.
