Pruning coffee plants is intended to stimulate generative growth that increases productivity to reach optimal. Plant Growth Regulator (PGR) makes it possible to exploit the production potential of plants. Pruning management, combined with the PGR in coffee plants, is expected to improve flowering and berry growth. The research was conducted for 7 mo from October 2017 to April 2018 at Gunung Gede, Bogor, West Java, Indonesia. A split–plot design with two treatment factors was used in this research. Pruning was placed as the main plot consisting of two levels, namely without (P0) and with pruning (P1). The PGR application was placed as a subplot, consisting of three dosages, namely without PGR (Z0), and concentrations of 0.3 mL L–1 (Z1) and 0.4 mL L–1 (Z2). The results showed, the pruning treatment significantly influenced microclimate, number of branches, B0, B1 and B2, number of berry sets, and berries. Pruning treatment had a very significant effect on microclimate, plant height, number of branches, number of coffee fruits, yields crops–1, and productivity. Interaction both significantly affected plant height and B0. The best dosage had not yet been found.

The oil palm should be replanted if it is 25 years old. The area of replanting of open oil palm will make the soil become dry, dense and will be easily washed so it will become less fertile. Therefore, soil conservation efforts are needed. Intercropping system pattern can be used as an alternative to land conservation in oil palm replanting area. The experiment was conducted at Cikabayan Experimental Estate, Bogor Agricultural University from February 2018 to May 2018. Research conducted using a completely randomized design environment with three replications. The treatment used in this research is corn monoculture, peanut monoculture, intercropping 1 row corn + 1 row of peanuts and intercropping 1 row of corn + 2 rows of peanuts. The results of the growth of corn showed that intercropping treatment gived higher plant growth, stem diameter and more leaf compared to corn monoculture. Similar results were also shown in peanut plants where intercropping treatment showed higher peanut growth compared to peanut monocultures. In yield per hectare variables showed that monoculture treatment yield higher than intercropping system. Treatment of corn and peanut monoculture yields per hectare greater than the intercropping treatment. However, the equilibrium ratio of the intercropping shows the result> 1. NKL ratio of intercropping treatment 1 row of corn + 1 row of peanut is 1.40 and intercropping 1 row of corn + 2 rows of peanuts 1.46.

Pest control program in coffee plantations is one of the most important activities in maintaining the value of production, productivity and cultivation of coffee. Based on observations in Bangelan Estate, there are many pests that attack coffee plant such as the fruit coffee borer (Hypothenemus hampei), mealybug (Pseudococcus citri), and black ant (Dolichoderus thoracicus). The intensity of coffee fruit borer attack (PBKo) and mealybug is low under 5%. The area of Plant Produce (TM) which attacked by black ant is classified as high as 32.7%. Black ants as a predators and decomposers of organic matter. By 2018, black ants belong to pests that must be controlled because they affect cultivation activities such as maintenance and harvesting coffee. Black ant control is done in an integrated way by mechanical (trapping) and chemical. Trapping is implemented by applying innovative methods from Bangelan Estate by installing bamboo that has been given litter of coffee leaves and molasses. This method is effective to control the pest. Keywords: attack intensity, chemical, mechanical, pest, robusta coffee

Bogor District is one of the Robusta coffee (Coffea canephora Pierre ex A. Froehner) producing areas in West Java. To estimate crop yield of Robusta coffee, planters usually count the amount of a given crop harvested in a sample area. Then the harvested crop is weighed, and the crop yield of the entire field is extrapolated from the sample. Recently by utilizing the geographic information system (GIS) used to determine the level of regional suitability combining with land productivity. It will help in analysing, planing and taking various policy for development Robusta coffee. This study aimed to estimate of yield potential of Robusta coffee. This research was conducted from November to December 2020 at Bogor District. The land suitability class for Robusta coffee in Bogor which was in the moderately suitable (S2) class of around 2% (5,227.78 ha), marginal (S3) 33% (99,189.20 ha) and not suitable (N) 65% (194,808.40 ha). The yield potential of Robusta coffee is obtained 105,030,473.1 kg or 105,030.47 tons. The highest yield potential of Robusta coffee is in Cigudeg and Sukamakmur subdistricts.
