Abstract

People with very severe disease or diabetes who need an increased increase, from close monitoring, received 2,866 who contracted blood sugar in 2007. One of the results of the study increased the resources used as an energy source controlled by insulin, according to the British diabetes agency, using A person's normal blood sugar level during fasting is 4.0 to 5.4 mmol / L (72 to 99 mg / DL), meanwhile. A person's normal blood sugar level two hours after eating is 7.8 mmol / L (140 mg / dL), but for people with hyperglycemia or high blood sugar levels. will have a sugar level of more than 180 mg / dL, while for sufferers of hypoglycemia or low blood sugar levels. will have blood sugar below 70 mg / dL. mmol / L is a unit of molecules to calculate the number of blood sugar molecules per liter, while mg / dL is a unit of measurement of milligram weight per deciliter for measurement of blood sugar levels. Blood sugar levels contain sugar or sugar in the blood. While constantly changing changes, sugar levels need to be maintained within normal limits so that disruption does not occur in the body. Blood sugar levels are needed by the intake of nutrients from food or drinks, especially carbohydrates, also the amount of insulin and the sensitivity of body cells to insulin. Blood sugar levels that are too high or too low will have a negative impact on health, both in the short and long term.

Abstract

Tomatoes are a type of vegetable that produces fruit. Ripe tomatoes will be bright red witha weight above 80 grams. Tomatoes can be found in the center of traditional shoppingmarkets and wet markets. The traders get tomatoes from farmers in large quantities sothat tomatoes are quite varied. There is a small red, there is a large tomatoes but not yetperfectly ripe and so forth. This is quite troublesome for traders in selling tomatoesbecause they have to be sorted first. To overcome this problem, we need a decisionmaking system to determine the quality of tomatoes and sort them. In this research, thedecision-making system to determine the quality of tomatoes using fuzzy logic Mamdanimethod and sorting tomatoes using Arduino-based conveyer. The result of the researchcan be demonstrated with the MATLAB application and manual count. The MATLAB andmanual results show no difference. The best quality tomatoes are at value 8 with red colorand large size. While the poor quality of tomatoes is at value 2 with green color and largesize. Green tomatoes are certainly not yet ripe and therefor the quality of tomatoes is stillpoor.

Abstract

Batam city is a city where many travelers passsing from local or overseas because it’s situated between Singapore and Malaysia so this city responsible to accommodate people such as hotel, although it’s high but there’s no tourism destination place that made travelers facing trouble to decide shortest path. Dijkstra’s algorithm is the answer for solving shortest path problem to our location. We can use present technology to decide which way is nearest with Google Map, but present technology doesn’t ensure us to give the best answer. Research about determination of closest distance culinary place using dijkstra’s algorithm with Open Street Map as the data source is conducted to see or compare the result from Google Map. The data in OSM is obtained by OSMnx, newest tool to capture data such as map and show visual of map. OSMnx can obtain data with ease by coding using python. The data result as visual between Google Map and OSMnx are same so OSMnx can give answer for choosing the shortest path, and accuracy of OSMnx to show the data is 85,7%.
