Abstract

The aim of the research was to determine the levels of protein, fiber, fat and corn marning texture given the interaction of lime concentration and soaking time. The problems with processed dried shelled corn products such as marning, emping, corn tortilla chips are that the texture is not crispy, less fluffy, relative nutritional components do not comply with SNI, the taste of the product is less varied and consumers don't like it so marketing is limited. The hard and less fluffy texture of corn kernels is caused by the complex network of starch and starch-protein complexes forming a hard matrix, so the right solution is needed. Several studies were carried out but the results were not optimal because the lime concentration, boiling time and soaking time were not correct, so research was needed to loosen the chemical bonds between starch complex compounds and hard starch-protein complexes by entering high-temperature lime water, which would result in cross-linking with ions. Calcium ions (Ca2+), the network is more open and tense which cannot be reversed during drying and frying so that the complex compound matrix network expands, giving crispiness to the product. This research is a factorial study of 2 factors: lime concentration and soaking time with 6 treatment interactions: A1B1, A1B2, A1B3, A2B1, A2B2, A2B3. The replication was 3 times so there were 18 experimental units. The research results show that lime concentration and boiling time influence the chemical and physical properties and marning of corn. Local corn marning meets the Quality Standards for Marning Corn according to SNI 01-4300-1996 in terms of texture and chemical properties of corn marning. The best treatment A1B3 for protein content is 8.729%; the best treatment A1B1 for fat content is 13,814%; The best treatment A1B3 for fiber content is 12.998%. The best treatment A1B1 for the physical properties of local corn marning with a texture value of 1580,500 mm/g.sec.

Abstract

ABSTRACT This research aims to determine and obtain a combination of treatments of sucrose concentration and cashew fruit pulp on sugar content, vitamin C content, total fiber content and activity of water of cashew jam. The factor in this research is the combination of sucrose + cashew pulp (A) in making cashew jam. This research was designed with 5 (five) treatment combinations of sucrose concentration and cashew pulp, namely: A1 = 45% sucrose + 55% cashew pulp, A2 = 50% sucrose + 50% cashew pulp, A3 = 55 sucrose + 45% pulp cashew pulp, A4 = 60% sucrose + 40% cashew pulp, A5 = 65% sucrose + 35% cashew pulp. The variables observed were vitamin C content, total sugar content, total fiber content and activity of water (Aw). The research data were analyzed using descriptive statistical methods which included mean and standard deviation or standard error/SE. The research results obtained were the highest vitamin C content: 154.142 ± 2.692 mg in treatment A1 (45% sucrose + 55% cashew pulp), the highest sugar content: 76.843 ± 0.103% in treatment A5 (65% sucrose + 35% cashew pulp ), the highest total dietary fiber content: 2.199 ± 0.029% in treatment A1 (45% sucrose + 55% cashew pulp) and the lowest activity of water: 0.745 ± 0.014 in treatment A5 (65% sucrose + 35% cashew pulp).

Abstract

This research was carried out in Golo Bore Village, Ndoso District, West Manggarai Regency. From June to July 2023. This research aims to determine the potential of several types of plants that function as attractants for golden snails in paddy fields in Golo Bore Village, Ndoso District, Manggarai Regency. West This research used a Completely Randomized Design method with four treatments and four replications at the research location in Golo Bore Village, Ndoso District, West Manggarai Regency which has rice fields that are entering the vegetative phase. The results of sagam testing show that attractant plant types have a significant influence very real in the golden snail population. The highest average population of golden snails was found in the taro leaf treatment, namely 33 individuals, followed respectively by papaya leaves, 27 individuals, banana leaves (20 individuals) and the lowest population of golden snails was found in the cassava leaf treatment, namely 16 individuals.
