Abstract

In retail stores, product variations and prices are the main attraction. Products with many discounts are the most sought-after products. The promotion itself requires a special method for determining the discount. The layout in supermarkets is also something that retail stores need to pay attention to. One method that can be used to determine the product layout, promo for each product is Market Basket Analysis. The purpose of this research is to determine associative relation that occurs between items and to find out the solution to the problem of layout arrangement, catalog creation, and determination of shopping vouchers in Gading Mas Swalayan 1 based on the output of Rapid Miner software. Based on the output results obtained 7 associative relationships that have a lift ratio value > 1 and it can be seen the determination of the layout of the item, catalog, and shopping voucher form. Layout changes are made for the comfort and convenience of consumers in taking the products they need and cataloging is determined by combining frequently purchased products with products that are rarely purchased. And the making of shopping vouchers is used to provide discounted prices where this is to reduce inventory and attract consumers.Keywords – Market Basket Analysis, Rapid Miner, Retail, The relation of associative

Abstract

Plant Root Growth Promoting Bacteria or PGPR are bacteria that colonize plant rooting areas or the rhizosphere to increase the quality or quantity of plant growth. PGPR can provide dissolved phosphate for plants to be absorbed by the plant root system since 95-99% of phosphate in nature is present in insoluble form. Soil samples from different irrigation systems from Akar-akar village were isolated through serial dilution techniques and grown on NA media shown that the higher the dilution, the fewer colonies that grew on the media. Macroscopic and microscopic observations were made to see the criteria for bacteria, shown that the bacteria in the three soil samples were gram negative and was known that bacillus and cocobacillus bacteria present in the three soil samples. Coccus bacteria was found in soil without irrigation and drip-surface irrigated soil, while streptococcus bacteria was found in drip-surface and drip-subsurface irrigated soil. As many as 22 bacterial isolates were isolated and grown on Pikovskaya media, only one bacterial colony was phosphate solvent through a clear zone that grew around the bacterial colony. The bacterial colony has a phosphate dissolving index (IPF) of 250, the ratio between colony diameter and clear zone diameter was 1: 1.5.Keywords – PGPR, Drip-surface irrigated soil, Drip-subsurface irrigated soil

Abstract

Prebiotics are food ingredients that cannot be absorbed by the host and will be fermented by colonic bacteria into Short-Chain Fatty Acid. Prebiotics can come from various natural ingredients such as wheat, onions, and bananas. Prebiotic food sources can stimulate the growth of probiotic bacteria which are beneficial bacteria for the host, one of which can produce bacteriocins to fight pathogenic bacteria. Manalagi mango (Mangifera indica L. var manalagi) is a fruit that has the potential as a source of prebiotics because it contains prebiotic food requirements, including dietary fiber and carbohydrates. The purpose of this study is to find out the ability or potential of Manalagi mengkal mango as a source of prebiotics by using a prebiotic test based on the growth of BAL is Lactobacillus plantarum in vitro. The design of this study used an experimental laboratory carried out in vitro by making carbon source media with various concentrations of mango flour, then mixed with liquid MRS, and given Lactobacillus plantarum culture which then measured the carbon source medium in the form of TPC. The highest TPC average yield was 1,7 x 1010 CFU/ml is the variation in the concentration of mango flour 6.89%. Based on the results of a prebiotic test with TPC mango flour manalagi mengkal showed its ability as a source of prebiotics by stimulating the growth of BAL (Lactobacillus plantarum).Keywords – Prebiotics, Manalagi mango, Lactobacillus plantarum

Abstract

In Indonesia, the prevalence of helminthiasis is still high, especially in children. The frequency is 60-70% in populations at risk. The lack of use of family latrines causes soil contamination with feces around the yard. There are still few articles that review the morphology of worms that cause infectious diseases in Indonesia. Whereas knowledge of morphology is important to understand the life cycle of worms that play a role in disease transmission in humans and mammals. This article aims to discuss the latest findings regarding the morphology of worms that cause infectious diseases in humans. It can be concluded that at the adult stage, worms can be sexed. Usually, the female type has a relatively larger size than the male. On the head (anterior) there are 3 lips that have sensor papillae, one on the mediodorsal and 2 on the ventrolateral. Between the 3 lips there is a bucal cavity which is triangular in shape and functions as a mouth.Keywords - Morphology, Helminth, Infectious disease

Abstract

Currently, many food products are containing Collagen and L-Glutathione. Based on recent studies, oral collagen supplementation has many advantages as a skin whitening agent, moisturizing agent, skin elasticity enhancer. Collagen supplementation has proven safe for short-term use in adult healthy subjects; however, there is no safety data on other group subjects such as pregnant women, breastfeeding mothers, and children. Meanwhile, there are so many food products containing collagen and L-Glutathione that claim their products give many advantages without any clinical study. The producer massively advertises their products to sell them without any complete information about side effects and warnings. The purpose of this study is to examine respondent’s purchase intention and awareness of this product's safety. The result shows that the respondent is likely interested in the claim they see in the advertisement. However, it has the potential unsafe use for pregnant women, lactating mothers and children, and long-term use. So this paper recommends BPOM to alter any regulation of food containing collagen especially on labeling and advertising and consider the product to become a food supplement instead.Keyword – Breastfeeding, Collagen, Whitening

Abstract

Bioplastics are environmentally friendly plastics derived from natural materials. Bioplastics are easier to decompose when compared to commercial plastics. Bioplastics are generally made from starch contained in plants. But the use of starch as a base material has the disadvantage of producing bioplastics that are not waterproof. Therefore, it is necessary to add chitosan to improve bioplastic characteristics. Chitosan usually comes from the shell of crustacean animals, but it turns out that in fish scales waste, also contains chitosan. Fish scales are a by-product of the process of fish processing. Fish scales are only discarded and not utilized so that they become waste that can pollute the environment. Fish scales have a chitin content that can process into chitosan, which can be useful as an additional ingredient in the manufacture of bioplastics. This review aims to find out the potential of fish scales waste as chitosan in the manufacture of bioplastics. Based on the results of previous research, fish scales have a chitosan content that can use as an additional ingredient in the manufacture of bioplastics. Fish scale chitosan can form bioplastic film with characteristic brownish-yellow film. The addition of fish scale chitosan is also able to improve the water resistance of bioplastic film. Based on the results of the review can be concluded bring fish scales to have the potential as chitosan that can use in the manufacture of bioplastic.Keywords – Bioplastic, Chitosan, Fish Scales.
