Abstract

The nata de coco cutting process takes place using three types of cutting machines, namely conventional cutting machines, conveyor cutting machines, and chain conveyor machines. The process of cutting nata often experiences practical problems, especially on the size of the pieces that do not match the predetermined criteria. This results in a decline in product quality and customer acceptance. The purpose of this study was to determine the causes of problems in the process of cutting nata de coco type NDC 12. Problem analysis was carried out using quantitative methods presented in the table of oversize nata de coco test data on each machine used so that deviations in the size of the nata produced against the criteria had been determined. determined, as well as qualitative methods with fishbone diagrams based on data from observations, interviews and documentation. The results of the size of the NDC 12 nata de coco pieces in general are still not in accordance with the standards set by the company, it can be seen from the average value of the largest defect in the chain conveyor machine, which is 12.75g pre-sorting treatment and 7.17g post-treatment. sort. This is largely due to machine work that is less than optimal and the pre-cutting process is not in accordance with work procedures.

Abstract

Innovative use of waste into herbal beverage products the waste treatment process starts from the stage of roasting cocoa beans, breaking the beans and peeling the skin, sorting, drying, preparation of packaging and materials, filling and mixing, giving silica gel and labelling the expiration date. The raw materials needed are cocoa bean husk, dried cardamom, and cinnamon powder. While the packaging material uses PET plastic bottle packaging. Before the product is marketed, it is necessary to conduct a feasibility analysis of the selling price. The analysis shows that the selling price of chocolate product of Rp. 15,000 is feasible because profit taking is 48% with the selling price per unit more than the cost per unit. The net profit margin of chocolate product of 32.6% means that the company is considered efficient in determining the selling price of its products and successfully controlling costs in it because the NPM figure is > 5%. Hedonic tests were also conducted to determine consumer acceptance of the product through a hedonic test of 20 panelists based on the parameters of color, aroma, taste, and packaging. The hedonic test scale 1 shows that consumers do not like it very much, a scale 2 does not like it, a scale 3 likes it, and a scale 4 likes it very much. The average level of preference for color parameters is 3.58, aroma is 3.31, taste is 3.47, and packaging is 3.84 which indicates that the panelists like these 4 parameters.

Abstract

Most farmers are experiencing challenges and constraints in accessing agricultural inputs, thus leading to poor and underutilization of agro-inputs and consequently low agricultural productivity in most part of sub-Saharan Africa. This study aimed to assess the agro-input supply sector in Kogi state. A total of 157 input dealers were randomly selected across the twenty-one local government areas in the state. Data were collected using well-structured questionnaire complemented with interview schedule and were analyzed using simple descriptive statistics. Findings reveal that agro-chemicals, fertilizer and feed were the major inputs supplied by most of the retailers and wholesalers that hardly engage in activities that create awareness about their products. Input prices were the most important preference and consideration factor in the purchase of agro-input by customers and form the basis for competition. Casual, family and child labors that proved to be cheaper, commonly accessible and do not require signing of formal employment contract with workers dominated both the retail and wholesale sectors. Poor government support, poor business condition in addition to poor capital base, high transportation cost, price fluctuations, adulteration were the identified major constraints affecting the agripreneurs. The study recommends capacity development on new marketing strategies, registration of businesses with relevant agencies, provision of credit and financial services; formation of formidable, strong and mutual-trust co-operative societies for input supply actors so as to enhance efficiency and effectiveness of the agricultural inputs supply sector in the state.

Abstract

Cheese is a dairy product that contains lactose so it cannot be consumed by lactose intolerant. Coconut milk can be used as an alternative to produce lactose-free cheese. This study contribution to investigate the effect of coconut milk and soy milk composition on the physical and chemical properties of coconut milk cheese, as well as product acceptability. Direct acidification using lemon juice is used to produce cheese with different coconut milk and soy milk composition (80:20; 70:30; 60:40). The properties assayed were yield, spreadability, and organoleptic. Yield of coconut milk cheese at composition 80:20; 70:30; 60:40 was 37.96%; 34.44%; 31.48%. Spreadability of coconut milk cheese at composition 80:20; 70:30; 60:40 was 9.83 cm; 9.65 cm; 9.53 cm. The difference of coconut milk and soy milk composition affects the physical and organoleptic properties of coconut milk cheese. Decrease in the level of coconut milk substitution and increase in the level of soy milk substitution led to decrease yield and cheese spreadability. Organoleptic score below 3 indicates that coconut milk cheese acceptability was still low.
