    Factors influencing GAP implementation on Robusta Coffee Farms in the Mountains of Indonesia
    (Universidade Federal de Lavras, 2024-08-05) Amrulloh, Atho’; Hani, Evita Soliha; Hariyati, Yuli; Soetriono; Harsono, Soni Sisbudi
    Robusta coffee is one of the plantation commodities that popular at home and abroad also as the biggest coffee product from Indonesia. This research aims to analyze the assessment of the level and influence factors of GAP implementation on coffee farmers in the Raung Argopuro Mountains region of Indonesia. The research was carried out in Bondowoso and Jember districts as one of the largest coffee producing centers in East Java with the coffee planting area located in the production forest area owned by Perhutani. The research data uses primary data from the results of assessing the level of GAP implementation among coffee farmer group members using an assessment model that refers to the 2014 RI Minister of Agriculture Regulation through actual assessments and in-depth interviews regarding implementation in the field. The method for determining and collecting data samples was carried out deliberately based on a multi-cluster random sampling model on members of a farmer group of 300 Robusta coffee farmers, divided into 150 coffee farmers in Bondowoso district and 150 coffee farmers in Jember district. Descriptive data analysis was used to see the level of GAP implementation by coffee farmers and logit model regression analysis was used to see the factors that influence the level of GAP implementation by coffee farmers in the research area. The research results show that the level of GAP implementation is divided into high and low implementation. The variables age, number of family members, land area and price variables are variables that have a positive and significant impact.

    Initial growth of Coffea canephora: Simulation of organomineral system and Limnoperna fortunei as soil improvement
    (Universidade Federal de Lavras, 2023-08-17) Barbosa, Mariana Cristina; Sena, Karla Nascimento; Maltoni, Kátia Luciene
    The use of residues can be an alternative to mineral fertilization. Manures, sources of nutrients and organic matter, are successfully used in family farming. Another residue that can be used for soil acidity amelioration is the shell of the golden mussel (Limnoperna fortunei), which is rich in CaCO3. This work evaluated the contribution of ground golden mussel shells (GMS) in combination with cattle (CTM) and sheep (SHM) manure to the initial growth of Conilon coffee in an acidic sandy soil. The experiment was carried out in protected cultivation in pots (30 kg) with two Conilon coffee cultivars. The treatments consisted of two doses of CTM (0 or 67 t ha-1) and four doses of GMS (0, 1, 2 and 3 t ha-1), with three replications. Each treatment was incorporated into the soil before the introduction of the seedlings in the experimental units, and 60 days later, a dose of SHM was applied on the soil surface (20 t ha-1). After 180 days, the soil fertility was analysed, and the seedling height, stem diameter, root volume and fresh and dry mass of the aerial parts and roots were measured. Furthermore, the Dickson Quality Index (DQI) was calculated. Both the sheep and the bovine manure increased the pH, the contents of P, MO, K+, Ca2+, and Mg2+, and the cations exchange capacity (CEC) of the soil. The addition of GMS increased the pH and the Ca2+ content while reducing the potential acidity of the soil. A pH above 6.0 reduced the levels of micronutrients in the soil. The use of CTM and SHM shows promise in the initial growth of coffee seedlings (height - H, FMAP, fresh and dry mass of the aerial parts - DMAP, FAR, fresh and dry mass of the root system – DMR diameter, RV root volume and Dickson Quality Index ). Ipiranga 501 surpassed Verdebras G35 in aerial fresh and dry mass, root volume and IQD, with or without the addition of 3 t ha-1 of ground GMS.

    Activity of robusta coffee on the expression of CRP and MMP-9 against hyperlipidemia
    (Editora UFLA, 2020) Prasetya, Rendra Chriestedy; Fatimatuzzahro, Nadie; Jatmiko, Widy
    Hyperlipidemia especially LDL accumulation causing inflammation in blood vessel. CRP and MMP-9 are component that triggering in inflammation process. This study to know activity of robusta coffee against hyperlipidemia on this component. This study using male wistar rats were divided into three groups ; normal, hyperlipidemia and that were given coffee with high fat diet groups. Robusta coffee was given 3.6x10-6 m3 by intragastric gavage. Blood collection was carried out using infra-orbital for analysis of LDL levels. Furthermore, the experimental animals were sacrificed and coronary arteries were taken for CRP and MMP-9 immunohistochemical staining. Data were analyzed using ANOVA followed LSD test. Results show The highest expression score for CRP and MMP-9 within the hyperlipidemia group was 188.27 ± 1.8 and 277.56 ± 2.1. The decrease in the expression score of CRP and MMP-9 happened within the ones that were given coffee with 59.33 ± 1.5 and 116.7 ± 0.2 each. Results showed that were differences in the expression of CRP and MMP-9 in all groups (p <0.05). In conclusion, activity robusta coffee can decreases the expression of CRP and MMP-9 against hyperlipidemia.
