ABSTRACT Oryctes rhinoceros L. is a major pest of Elaeis guineensis Jacq. which can reduce yield by 69% at the first harvest and cause 25% mortality in immature plants. Biological control using the fungus Metarhizium anisopliae (Metsch.) inoculated into compost can control the population of O. rhinoceros and can increase the growth of E. guineensis seedlings. This study aims to obtain the …
ABSTRACT Indonesia is known as an agricultural country that relies heavily on the agricultural sector, one of which is oil palm plantations. Oil palm plants produce oil palm trunk waste which can be used as a substrate for the growth of lactic acid bacteria (LAB). One of the LAB strains that can produce amino acids and antioxidants is Enterococcus faecalis. The purpose of the research was to d…
ABSTRACT The oil palm plant (Elaeis guineensis Jacq.) is a plant that produces food oil, industry and biofuel. Palm oil replanting is the process of replacing old and damaged plants with new plants to increase the productivity of oil palm plantations. This research aims to determine the effect of the interaction of solid compost and NPKMg fertilizer, solid compost factors, NPKMg fertilizer and…
ABSTRACT Lemang bamboo is classified as a semi-wet food product with moisture content ranging from 10-40%, and water activity (Aw) ranging from 0.65-0.90 so that it can be used as a medium for the growth of microorganisms that can cause damage. This study aims to determine changes in chemical, microbiological and sensory characteristics of bamboo lemang in various types of packaging (banana l…
Universitas Riau ABSTRACT Marshmallow is a type of candy that has a soft foam like texture and melts in the mouth when eaten. The use of natural dyes such as butterfly pea flower extract and the addition of gelatin concentration in making marshmallows is expected to produce good marshmallow characteristics. The study aims to obtain the right gelatin concentration in making butterfly pea flowe…
ABSTRACT Regeneration of human resources in agriculture by younger farmers who are living with social media, called digital humanities, is one of the steps of its sustainability. This research aims to analyse regeneration of agricultural human resources model in Rumbai District of Pekanbaru City. The research used a survey method where 60 young farmers were taken as the samples. The data were …
ABSTRACT Probiotics are live microorganisms that have benefits are given in sufficient quantities to their hosts. This study aimed to determine the autoaggregation, coaggregation, and cell surface hidrofobicity abilities of Limosilactobacillus fermentum InaCC B1295 and Pediococcus pentosaceus strain 2397 encapsulated in cellulose microfiber (CMF) hydrogel from oil palm fronds. This study was ca…
ABSTRACT Pineapple peel can be used as a natural ingredient in making mosquitorepellent lotion. This research aims to determine the best pineapple peel extract for the characteristics and effectiveness of the anti-mosquito lotion produced. Pineapple skin was extracted using the maceration method with 96% ethanol solvent. The research was carried out experimentally using a Completely Rando…

The tofu industry in Rambung Merah Village is a small-scale business that has the potential to be developed. This can be seen from the number of tofu demand that …
ABSTRACT Palm trunk contains cellulose that can be hydrolyzed into glucose as an alternative substrate for bacterial growth namely, Brevibacterium sp. InaCC B46. The purpose of this research was to determine the interaction between incubation time and concentration of Brevibacterium sp. InaCC B46 in producing amino acids and antioxidant activity. The research method used a factorial comple…
ABSTRACT Corn (Zea mays L.) is the second important food in Indonesia after rice. One of the problems encountered in maize cultivation is the attack of the corn fall armyworm (Spodoptera frugiperda J.E., Smith). The corn fall armyworm S. frugiperda is a threat in maize cultivation, because it can cause a decrease in production of 5-20% when the larvae attack the leaves and 100% when the larvae…
ABSTRACT Sago (Metroxylon spp.) is an important crop in Indonesia, particularly in the Meranti Islands, which have vast peatlands as its ideal habitat. This study aims to identify the physiological characteristics of several sago accessions based on photosynthetic rate, stomatal density, chlorophyll content, and leaf area index. The research used a Split Plot Design with location (A38, C33, an…
ABSTRACT Sago palm (Metroxylon spp.) is a carbohydrate-producing plant that serves as a staple food in several regions of Indonesia, such as Maluku and Papua. However, increasing industrial demand has led to excessive exploitation, causing genetic erosion.
