Abstract

Kappaphycus striatum and Kappaphycus alvarezii are kappa carrageenan-producing seaweeds. K. striatum is also a source of iota carrageenan. The study was aimed to evaluate the effects of extraction time and alkali concentration on the characteristics of semi refined carrageenan (SRC) produced from seaweeds K. striatum and K. alvarezii. The SRC was extracted prepared by cooking dried seaweed samples in KOH solution (ratio seaweed:KOH solution= 1:40) with KOH concentrations of 6, 8 and 10% for 60 and 120 minutes at 70°C. The results showed that the best SRC characteristics produced from K. striatum seaweed were obtained from the extraction process at 6% KOH for 60 minutes which yielded 46.05±0.16%, carrageenan with gel strength of 362,07±21,44 g/cm2 and viscosity at 70°C 74 cP. Meanwhile the best characteristics of SRC produced from K. alvarezii seaweed were obtained from extraction in 10% KOH for 60 minutes having the highest yield of 39,03±0.95%, gel strength 1130.67± 16.34 g/cm2 and viscosity at 70°C of 59 cP. FTIR analysis showed that the functional groups which are kappa carrageenan and iota carrageenan characteristics were found in both samples at wave numbers of 846.97-847.09 and 800.53-801.29 cm-1, respectively.

Abstract

Karagenan merupakan kelompok polisakarida yang dihasilkan melalui proses ekstraksi rumput laut menggunakan air pada suhu tinggi maupun dengan larutan alkali. Penelitian ini bertujuan untuk mengetahui pengaruh perbandingan volume air pengekstrak dengan karagenan semi murni terhadap karakteristik karagenan yang dihasilkan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan rasio air yaitu 1:40; 1:50; dan 1:60. Hasil penelitian menunjukkan rasio air memberikan pengaruh nyata pada rendemen, kadar sulfat, dan kekuatan gel, tetapi tidak berpengaruh nyata pada kadar air. Karakteristik karagenan terbaik dihasilkan pada perlakuan 1:60 dengan kadar air 11,26 ± 0,52%, rendemen 28,00 ± 0,23%, kadar sulfat 18,87 ± 0,57%, kekuatan gel 1370,73± 23,57 g/cm2, dan viskositas puncak sebesar 70 cP. Analisis spektoskopi inframerah transformasi fourier (FTIR) menunjukkan bahwa daerah khas kappa karagenan terdeteksi pada semua sampel pada bilangan gelombang 846 cm-1.

Abstract

Honey has many benefits. Thus, honey counterfeiting often occurs with the ever-increasing demand. However, many do not know how to distinguish between real and fake honey, even honey breeders and hunters find it difficult to tell the difference. The honey used to test the quality of honey is honey produced by Apis dorsata bees or wild bees, the nectar consumed by these bees is the kesambi tree, the kesambi tree that grows a lot on the slopes of Mount Tambora, Bima district. Honey contains a lot of antioxidants such as vitamin C, pinocembrin, chrysin, pinobaksin, catalase, and many other ingredients that are very beneficial for the health of the body. Testing the authenticity of honey using two sensors, namely a gas sensor and a color sensor, the tool has been connected to a database and web application to display test data. The web application can be accessed from any location as long as it is connected to the internet network. The results of the research are the ideal distance for measurements is carried out as far as 2 cm. The success rate in testing pure honey with a mixture of honey has different values, such as the value of pure honey has a gas sensor voltage of 3.3 volts while the value of mixed honey with 50% pure honey and 50% sugar, the value of the gas sensor voltage is 2.54 volts. Mixed honey has a voltage below 3 volts. The results of the color sensor test, namely the sensor output have different values, the RGB value for pure honey is red 206, green 246, and blue 182 while the RGB value for mixed honey is for 20% pure honey and 80% sugar mixture produces an RGB value of Red 156, Green 210, Blue 171. The color sensor can distinguish between real honey and mixed honey for trigona honey.

Abstract

East Lombok is one of the districts in the province of West Nusa Tenggara which still has a high number of children with undernutrition. Undernutrition is a condition in which the body does not get adequate nutritional intake for growth, development and maintaining health. The purpose of this community service activity is to provide knowledge to the community and students about the gut microbiota and the role of probiotics on gastrointestinal health in malnourished children. The method of this activity is counseling and filling out questionnaires before and after counseling. Based on the results of the questionnaire, it was found that there was an increase in the knowledge of the counseling participants, namely 100% of the participants knew the benefits of balanced nutrition in children; the definition of stunting, undernutrition and malnutrition; the effect of good nutrition on development and growth; undernutrition causes children to experience developmental disorders, reduced levels of intelligence and academic achievement; and probiotics and the role of probiotics for gastrointestinal health. However, only 47% of participants were able to answer foods that were included in the 4 healthy 5 perfect foods. So we conclude that the target of this community service activity already understands the socialization material presented.
