The brown planthopper (BPH) (Nilaparvata lugens Stal.) is main pest of rice plants and cause hopperburn and viruses vector. The BPH control uses an entomopathogenic fungus is Riau local rice field isolate Metarhizium anisopliae. This isolate was obtained from rice plants in Kampar, Riau. The research was aimed to get the best concentration and the right concentration in killing the BPH. Research was conducted at Laboratory of Plant Pests, Faculty of Agriculture, Riau University from June to April 2023. The research was conducted experimentally using a completely randomized design (CRD) with 6 treatments and 4 replications. The treatment was concentration of 0, 40, 50, 60, 70 and 80 g.l-1 aquades to obtain 24 experimental units. The parameters for observation were initial time of death, lethal time 50%, lethal concentrations of 50 and 95, daily mortality and total mortality. The results research shows concentration of 40 g.l-1 aquades (0.90 x 106 kon.ml-1) was the best concentration cause a total mortality of 72.50 ± 9.57%, the initial time of death 163.50 ± 6.45 hours after application and lethal time of 50 206.25 ± 9.77 hours after application. The right concentration in killing 50% and 95% of BPHs was 2.11% and 10.45%..

Tonrong Village is one of the villages in the Baranti District,Sidenreng Rappang Regency, South Sulawesi Province. There are several duck/duck breeders and business groups of boiled salted eggs which are produced traditionally with not too large a production amount, due to limited marketing caused by the many similar industries, both in the same village and sub-district, even in almost every sub-district there are also people who production of boiled salted eggs. Inspired by the smoked salted eggs of Brebes, the team took the initiative to make a smoking furnace/tool to produce Tonrong smoked salted eggs, through Community Service activities. The smoking process can be done on salted eggs that have been boiled or steamed, of course with different results. The smoking process is carried out in the following settings: steamed salted eggs, processed for 30 minutes of steaming at a temperature between 70-75oC for maximum results. The result is for steamed eggs, perfectly cooked eggs, especially seen from the appearance of the egg yolks, but contain water so it is a bit soft while for eggs treated with smoking, salted eggs have an attractive color, a distinctive smell and very little water content so that the shelf life is more durable. compared to salted eggs that are steamed or boiled.

The Rhinoceros beetle (Oryctes rhinoceros) is the main pest of palm oil (Elaeis guineensis Jacq.). Biological control using Metarhizium anisopliae fungus was effective in controlling O. rhinoceros. M. anisopliae fungus can be applied on palm oil empty bunches (POEB) which composted (Metankos). The research result in 2019 that a concentration of 50 g.l-1 M. anisopliae only kill 56% of O. rhinoceros larvae, so an increase in application concentration was tested. This research aimed to obtain the best concentration by increasing the concentration of M. anisopliae in POEB compost mixed with sawdust in controlling O. rhinoceros L. larvae. The research was conducted at The Plant Pest Laboratory Faculty of Agriculture University of Riau, to January until April 2021, using a completely randomized design (CRD), consist five treatment and four replications, concentration of M. anisopliae in compost was 55 g.l-1 water, 65 g.l-1 water, 75 g.l-1 water, 85 g.l-1 water, 95 g.l-1 water. The research showed that an increase in the concentration of M. anisopliae in compost of 75 g.l-1 water could be categorized as biopesticides because it caused an total mortality is 72,50 ± 5,00. The lethal concentrations 50% and 95% of M. ansiopliae in compost is 48 g.l-1 water approach to concentration 55 g.l-1 water and 140 g.l-1 water approach to concentration 95 g.l-1 water.
