Abstract

Increasing population growth has an impact on increasing food demand, one of which is wheat flour. Increasing imports of wheat flour is not the solution. Canna tuber has high carbohydrate content. But it has a brownish color, low solubility and swelling power. The purpose of the study was to determine the optimum conditions to increase the quality of Canna starch by oxidation process using hydrogen peroxide (H2O2) as an alternative flour according to the quality standard of SNI 3751:2009. The research used white canna tubers as raw material to make canna starch. The starch was oxidized using H2O2 (1%, 2%, 3%) with variables slurry ratio of 10%, 20% and 30% within 30, 60, 90, and 120 minutes. The highest value of solubillity and swelling power was got at 60 minutes process and 10% slurry. The modification process is continued to find the optimum H2O2 concentration. The highest swelling power and solubility were obtained at 2% H2O2. The optimum condition is 10% slurry concentration, 2% H2O2 and 60 minutes oxidation time. The value of swelling power is 2.9 and water solubility is 0.0609. Proximate analysis was found 85.956% carbohydrates, 2.365% protein, 0% fat, 11.425% water and 0.254% ash. While the results of the white degree test show a brightness value of 91.95. Total protein did not reach the SNI standard, but modified canna starch can be used as substitute for wheat flour as much as 50% according to the test result of bread making application.

Abstract

The world of education is currently developing, various kinds of innovation and renewal are carried out to improve the quality and quantity of education. Various breakthroughs have also been made both in curriculum development, learning innovation, and the provision of educational facilities and infrastructure needed to improve the quality of education itself. The method used in this study is a quantitative descriptive method with an Ex Post Facto approach. The population of this study is class X students of SMA Negeri 8 Pontianak for the 2023/2024 school year.The data collection techniques in this article are direct communication techniques and also use questionnaires. The validity test of the instrument is used to assess whether the instrument can accurately disclose the data of the variable being studied. The validity of the content and construct was assessed through expert assessment by three validators, consisting of two IT lecturers and one Informatics teacher, to evaluate the suitability of the questionnaire about learning interests and learning disciplines. The data from this research includes information about students of SMA Negeri 8 Pontianak class XA, XB, XC, XD, XE, XF, XG, XH, XI which amounted to 322 students who had previously been observed, this was done to find out the problems at SMA Negeri 8 Pontianak before a study was conducted. The research carried out included one bound variable, namely Learning Outcome (Y), and two independent variables, namely Learning Interest (X1) and Learning Discipline (X2) Variable Data for X1 and X2 was obtained from a questionnaire with a likert scale answer model of 4 (four) alternative answers that were distributed according to the sample needs to 167 students who were the research sample.

Abstract

Early childhood education (4-6) years is focused on developing creativity in order to create the next generation of problem solvers. The majority of students in the Arena Belajar KIDS learning center tend to overplay on gadgets so that creativity and brain concentration decrease. One solution to break this addiction is to invite students to participate in getting to know nature more closely. This activity aims to increase children's creativity and awareness by cultivating lettuce with the hydro-DFT system. The materials used are lettuce seeds of Lactuca sativa variety, netpot, rockwoll, hydroponic nutrients with a mass ratio (1:5) toward (1:3) on last week. The tools used include water pumps, hoses, TDS & pH meters, and hydro-DFT devices that work with the fertigation system. The final result is the harvest of lettuce after a 30-day planting period with average 19.44 cm plant height, 11.92 number of leaves, and 101.78 gr fresh weight. The harvest was carried out based on the feasibility of lettuce specifications that were fertile above 60%. Lettuce harvest from a total of 20 netpots with the hydro-DFT fertigation system showed 70% cultivation success. The average level of feedback on the program series is very good (4), as evidenced by projects that all goes as schedule and are solutive to partner problems. It is hoped that cooperation with partners will continue so that in the long run it can create independent vegetable gardens in the school or  in the home of each student and teacher.
