AbstractThe main purpose of this study was to determine the chemical composition of monofloral bee-collected pollen from the coffee (Coffea robusta) plant and its pellet morphology. According to the results coffee bee pollen (CBP) has a high nutritional value. It contains a large percentage of protein, reducing sugar, and lipid. Also, vitamins (B2 and E) and minerals (K, Ca, and P) were found in CBP. In addition, the results revealed that the total polyphenols content (TPC) was 10.62 mg GAE/g dry weight (DW) and antioxidant activity (AA) of CBP was 5.52 μmol TE/g DW. Some physical properties of CBP pellet were recorded such as moisture, relative diameter, sphericity, bulk density, and colour parameters. The pollen pellet exhibits shapes of colour from light to dark yellow. These results pointed out that CBP can be used as a remarkable source of compounds with antioxidant activity and health-protective capacity for humans.

Abstract. Supeno B, Erwan, Agussalim. 2021. Enhances production of coffee (Coffea robusta): The role of pollinator, forages potency, and honey production from Tetragonula sp. (Meliponinae) in Central Lombok, Indonesia. Biodiversitas 22: 4687-4693. The bees role as an agent of pollinators to improve the productivity of plants. This study was purposed to enhance coffee production (Coffea robusta) by roles of stingless bee Tetragonula sp. as pollinator agent, forages potency, and honey production. This study has been conducted in a coffee plantation in Lantan, Central Lombok, Indonesia. Several parameters were measured such as the number of bunches and flowers, production of nectar and pollen, sucrose nectar content, production of coffee, production of honey, honey stomach volume, and pollen weight. The results showed that the different observation time influenced the number of bunches, flowers, production of nectar and pollen, sucrose nectar content (P<0.01). The number of bunches ranged from 58.2 to 144.9 bunches/tree, the number of flowers 36.3 to 58.7 flowers/bunches, and 2,362.5 to 8.250.6 flowers/tree. Furthermore, the nectar production 9.16 to 33.85 g/tree, pollen production 1.72 to 5.95 g/tree, sucrose nectar content 20.6 to 35.0%. Estimation of coffee production before pollinated by Tetragonula sp. was 1,230.8 kg/ha, but after pollination by Tetragonula was increased it became 3,605.7 kg/ha (49.1%). Fruit production before pollinated by Tetragonula sp. was 2,127.2 fruit/tree, but after pollination by Tetragonula sp. increased to 8,309.2 fruit/tree (59.2%). Production of honey from Tetragonula sp. was 3.74 g/hive/5 months and in Apis cerana was 301.35 g/hive/5 months. It can be concluded that the Tetragonula sp. as an agent of pollinators can enhance the production of coffee and increase the biodiversity of coffee.

Peel Extract

Now in these days infectious diseases seriously affect human health and sometimes these infections might become the cause of human mortality. Most of these infectious diseases are caused by bacteria, viruses, and fungi. Although large numbers of antibiotics are available increasing drug resistance in these microorganisms became a serious matter of concern in the scientific community. There is an urgent need for research on alternate natural products that can manage these pathogenic microorganisms without inducing any resistance. The purpose of this study was to determine the antibacterial activity of Robusta coffee (Coffea robusta L.) fruit peel extract against 5 human pathogenic bacteria i.e. Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Salmonella thypi NCTC 786. The sample was extracted using the maceration method with methanol as the solvent. The antibacterial activity of fruit peel extract was determined by using the agar diffusion method while the presence of active ingredients was determined by the using TLC-Bioautography assay performed using the mobile phase of n-hexane: ethyl acetate (1 : 3). The results of the study revealed significant antibacterial activity of coffee peel extract against E. coli and B. subtilis with an inhibition zone of 10.15 mm and 10.96 mm, respectively. Furthermore, results of the TLC-Bioautography revealed that the compounds at Rf 0.76 inhibit the growth of E. coli and the compounds at Rf 0.27 inhibit the growth of B. subtilis bacteria. These active spots were suspected to be flavonoid and phenolic compounds, respectively but further confirmation detail study is required in the future.

El café es un cultivo de importancia social y comercial, se estima que es el sustento de 25 millones de familias en las regiones tropicales y subtropicales del mundo. Con el objetivo de evaluar el crecimiento, desarrollo y concentración de macronutrientes en genotipos de café con diferentes dosis de abono orgánico se realizó un ensayo en el centro experimental Sacha Wiwa, bajo un diseño de bloques aleatorios con arreglo factorial (genotipos x dosis de abono orgánico Bioabor®). Las variables que se midieron fueron altura de planta, diámetro del tallo, concentración y relación de macronutrientes en el tejido foliar, análisis físico y químico del suelo al inicio y final del estudio. Los datos fueron analizados con estadística descriptiva univariante y técnicas paramétricas. Para la comparación entre medias se empleó el test Tukey al 95% de probabilidad. La variedad Ecorobusta fue la que obtuvo la mayor altura y diámetro de tallo. El abono orgánico inhibe el crecimiento y desarrollo del cultivo de café. Las dosis de abono a 1000, 1500 y 2000 kg /ha aplicada en este orden en la variedad NapoPayomino, Ecorobusta y Conilón reducen la concentración de N en el tejido foliar. Se encontró una correlación positiva significativa entre la altura de planta y diámetro del tallo.

The effects of various growing media and liquid organic fertilizers on the growth of robusta coffee (Coffea robusta L.) seedlings. The research was conducted for 12 weeks (3 months) from March to June 2020. The research was conducted at the Agrotechnology Experimental Garden, Widya Gama Mahakam University, Samarinda. This study aims to determine: 1. The right planting media for the growth of robusta coffee (Coffea robusta L.) seedlings 2. Liquid organic fertilizer (POC) is appropriate for the growth of robusta coffee plant seedlings (Coffea robusta L.). 3. The interaction between planting media and liquid organic fertilizer (POC) on the growth of robusta coffee (Coffea robusta L.) seedlings. This study used a factorial randomized block design (RBD) with 2 factors and repeated 3 times. The first factor is the Planting Media (M) which consists of 4 levels, namely, M1 = Soil, M2 = Soil + Rice Husk (2: 1), M3 = Soil + Sawdust (2: 1), M4 = Soil + Coconut Coir ( 2: 1). The second factor is Liquid Organic Fertilizer (P) consisting of 3 levels, namely: P0 = Topsoil (control), P1 = POC 50% Fragrant Lemongrass Tofu Wastewater (ALTSW) (500 ml ALTSW + 500 ml water), P2 = POC Extract Gamal leaf (EDG) (500 ml EDG + 500 ml water). Based on the research results, the following conclusions can be drawn: 1. There is a significant effect of the application of growing media on the increase in height, stem diameter, and the number of leaves. Soil media with rice husks gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. 2. There was a significant effect of POC application on height increase, stem diameter, and the number of leaves. The liquid organic fertilizer of Gamal leaves gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. 3. There is a media interaction with liquid organic fertilizer (POC) which has a significant effect on the increase in height, stem diameter, and number. The combination of soil growing media treatment with rice husks and Gamal leaf POC gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. The expected output is to provide information about the best planting media for the growth of Robusta coffee seeds for the community. Providing information about the best liquid organic fertilizers for the growth of Robusta coffee seeds for the community. Keyword : Gamal Leaves, Tofu Dregs Waste, Wood Powder
