ABSTRACT Sago plants are a type of palm that can serve as a carbohydrate source due to their high starch production. However, using natural sago starch in food products and its processed derivatives remains limited. Natural sago starch has certain limitations in its physicochemical characteristics. These limitations can be addressed through dual modification, specifically fermentation and auto…
ABSTRACT Tubers in Indonesia are a source of carbohydrates after cereals, and have many types, one of which is purple sweet potato. Purple sweet potato has a complex nutritional content so that it has the potential to be made into various forms of processed food, one of which is jelly candy. Jelly candy generally adds fruit juice or essense in adding aroma, color, and distinctive taste and…
ABSTRACT Probiotics are live microorganisms that confer health benefits to the host if consumed in sufficient quantities. The activity of bile salt deconjugation and inhibition of pathogenic bacteria needs to be carried out on Limosilactobacillus fermentum InaCC B1295 and Pediococcus pentosaceus strain 2397 with and without CMF hydrogel encapsulation from oil palm fronds. This study was ca…
ABSTRACT Dry noodles are popular in Indonesia and primarily made from wheat flour. In recent years, there has been increasing interest in using sago starch as a glutenfree food alternative. Heat moisture treatment (HMT) can modify sago starch properties, depending on processing conditions like moisture content. This study aimed to evaluate the effect of varying moisture content during HMT …
ABSTRACT Marshmallow is a soft candy with a soft, chewy texture and a distinctive sweet taste. Natural coloring, such as rosella flower petal extract, is expected to provide good marshmallow characteristics. This research aimed to determine the best marshmallow treatment by adding rosella flower petal extract to its physicochemical and sensory characteristics. This research was carried out…
ABSTRACT Welsh onion (Allium fistulosum L.) is an important horticultural commodity widely used as a culinary ingredient. One of the main challenges in its cultivation is the low availability of nitrogen (N) in Inceptisol soil. This study aimed to determine the effect of various nitrogen doses on the growth and yield of Welsh onion and to identify the optimal nitrogen dose. The research wa…
ABSTRACT Coconut (Cocos nucifera L.) is one of the plantation commodities with economic value due to its various benefits. Coconut plants are widely cultivated by communities, both as a source of oil and as raw material for the food industry. However, the limited availability of superior seeds and the increasingly low productivity are the main problems. This study aims to analyze the quali…
ABSTRACT The soursop plants in Riau is still relatively low compared to other fruit plants, one of the causes is slow germination. This study aims to determine the effective interaction between potassium nitrate concentraction and seed soaking duration to break the dormancy of soursop seeds. The research was conducted at the Plan Ecophysiology Laboratory and greenhouse of the Experimental …
ABSTRACT This study aims to determine the components of genetic diversity, herritability, and genetic correlation between components of corn crop yields so that it can determine which characters can be used as alternative selection criteria. This research was carried out experimentally using a random group design with genotypes consisting of 12 genotypes. Each genotype was repeated 3 times…
ABSTRACT Acid soils generally have high hydrogen ions and cause the soil to react acidically. One of the impacts that arise as a result of acid pH is the low P available to plants. Increasing the efficiency of available phosphate can be done by utilizing phosphate solubilizing microorganisms. Phosphate solubilizing bacteria also play a role in dissolving insoluble phosphate into soluble, b…
ABSTRACT Rice plants (Oryza sativa L.) are very important food crops. Rice productivity needs to be increased in order to maximize production by improving the quality of rice seeds. One effort that can be made to improve the quality of rice seeds is to utilize bacteria containing the hormone indole acetic acid (IAA). The ability of IAA to stimulate cell elongation modifies certain physiolo…
ABSTRACT This study aimed to evaluate the degradation rate of chlorpyrifos due to sunlight exposure and exposure duration in peat soil. The research was conducted experimentally using a factorial Completely Randomized Design (CRD) with two treatment factors. The first factor was sunlight exposure (direct and indirect), and the second was the duration of exposure (0, 7, 14, 21, and 29 days). Ea…

ABSTRACT Sweet corn (Zea mays saccharata Sturt.) is a type of corn that is often consumed fresh and used as raw material for the food industry because of its higher sugar content compared to other types of corn. This research aims to determine the effect of the interaction of Empty Fruit Bunch Oil Palm ash (EFBOP ash) and NPK fertilizer, the effect of applying EFBOP ash and NPK fertilizer …
ABSTRACT Maize (Zea mays L.) is an important commodity as food, animal feed and others. In Riau Province, maize production is declining due to pest attacks, especially aphids (Hemiptera: Aphididae), which can reduce yields by up to 78%. Aphids damage plants by sucking fluids, producing honeydew, and becoming virus vectors. Observations on the species and abundance of aphids are needed to …
ABSTRACT Oil palm (Elaeis guineensis Jacq.) is the primary source of vegetable oil, with higher productivity compared to other oil-producing crops. In Riau Province, the area of oil palm plantations continues to expand annually. This expansion has led to an increased demand for large quantities of seedlings, thereby necessitating effective nursery practices. In oil palm seedling cultivatio…
