Due to extended inundation, waterlogging and restricted below-ground aeration cause inhibition in plant growth performance. This study examined two different rubber clones, RRIM 600 and RRIT 251, for waterlogging and restricted below ground aeration. To evaluate the plant performance under the stress conditions, net photosynthetic rate (PN), maximum quantum yield photosystem II (Fv/Fm) and root elongation rate were observed. RRIM 600 has a higher photosynthetic performance under normal conditions. However, the PN rate and Fv/Fm ratio trend showed that RRIM 600 seems to have difficulties recovering after exposure to restricted-below ground aeration. Although RRIT 251 had a lower tendency of PN rate under normal conditions, the PN rate and Fv/Fm ratio of this clone showed fast recovery. RRIT 251 also performed a higher trend of root elongation rate under both stress conditions than RRIM 600.

Rubber trees are one of the main tree crops in Southeast Asia that provides latex as the primary source of tire production. However, commercial clones of rubber trees are attacked by pests such as root and foliage diseases and are exposed to abiotic stresses such as drought, which make the development of resistant rubber clones to biotic and abiotic stresses crucial. This mini review highlights the breeding program to develop resistant rubber tree crops through crossing and biotechnology, including in vitro culture and genetic transformation.

Animal fertilizer comes from animal waste and has undergone a decomposition process. The use of animal fertilizer has a potential risk to farmers' health if they do not heed Occupational Health and Safety (K3) standards for the personal safety of coffee farmers. The impact is that coffee farmers can be infected with worms transmitted through the soil (Soil Transmitted Helminth). This community service activity aims to increase the knowledge of Cibulao coffee farmers about preventing Soil-Transmitted Helminth worm infections in the application of animal fertilizer through counselling and technical guidance. The community service partners are the Cibulao coffee farmer group. The methods used are counselling, technical guidance and evaluation. The number of participants who attended this technical guidance was 17 coffee farmers. The training occurred in Telaga Saat Village, Cisarua District, Bogor Regency. The results of this community service activity show that there has been an increase in understanding of measures to prevent STH infection when using animal fertilizer. This increase can be seen from the pre-test and post-test results carried out before and after providing the material and technical guidance. The success of this program can be seen in farmers who are skilled in applying animal fertilizer using K3 and the desire for sustainable technical guidance regarding the maintenance and health care of goats and sheep.
