Indonesia is an agricultural country that has great potential for the development of tropical fruits, horticultural crops and vegetables. Vegetables are important foods that are needed by the body because they contain nutrients needed by the body. However, some sweet potatoes that contain nutrients have not been adequately studied and utilized, including sweet potato (Ipomoea batatas L) from the Convulvulaceae family (Suparman, 2007). Sweet potato plants (Ipomoea batatas L) from 1968 until now have been widely produced, even Indonesia was the fourth largest country that produced sweet potato plants.The objectives of this study were: 1) Knowing the process of making purple sweet potato Gel candy; 2) Knowing consumer acceptance of purple sweet potato Gel candy products; 3) Knowing the nutritional content of purple sweet potato Gel candy. The methods used in this research include literary, documentation, experimental, organoleptic, hedonic and nutritional content methods. The resulting data is then processed and evaluated and then presented in tables and diagrams with in-depth explanations.The results showed that the best formula composition is found in code 472 The characteristics of the purple sweet potato gel candy produced are sweet and sour taste, candy aroma, solid chewy texture, light purple color. The panelists' acceptance of the making of purple sweet potato gel candy through the hedonic test results showed that the most favored by the Panelists were the product code 472 with a composition of 60 grams of sweet potato, 75 grams of gelatin, 75 grams of sugar, 1 gram of himalaya salt.

The nutritional problems faced in Indonesia today remain the same, namely that many children suffer from malnutrition. The national movement to increase breastfeeding is one of the government's efforts to improve the health status of mothers and children. However, the achievement of exclusive breastfeeding has not been achieved, one of the reasons is the breastfeeding factor. Meanwhile, the point in the success of providing exclusive breastfeeding and continuing it for up to 2 years is related to a mother's understanding of lactation management. So this service activity is carried out to teach mothers who are young pregnant, late pregnant and have just given birth to a 1 month old baby to participate so that their knowledge increases. The method in this activity is a pre-test before providing information related to breastfeeding and lactation management, then continuing with the post-test to see the success of the activity. The mothers' enthusiasm was seen to be very high and resulted in a strong determination to be able to provide exclusive breast milk to their babies. The success rate of this activity was 80%, judged from the responses and questions from the participants.

Background: MPASI is a food transition from breast milk to family food. Giving MPASI should be given to infants aged 6-24 months in stages both from the texture and number of portions. Proper provision of complementary feeding can lead to nutritional problems in infants. Proper processing and administration of MPASI, mothers are required to have sufficient knowledge so that they can create healthy babies. Objective: to describe the knowledge of mothers about nutritious food and complementary feeding in infants aged 6-12 months. Method: This study uses an explorative descriptive design. The technique of taking respondents of this study was purposive sampling with a total sample of 25 mothers who had babies aged 6-12 months in Posyandu Dusun Kangin, Tusan Banjarangkan Klungkung Village. Data collection tool in the form of a closed questionnaire. Data analysis uses univariate analysis on a qualitative scale. Results: the study showed the characteristics of respondents, most of whom were aged 21-25 years (56%), working (56%), elementary education (44%), and the level of knowledge of mothers in the less category (40%) Conclusion: This study found that most levels of maternal knowledge about nutritious food and complementary feeding were lacking (40%), so further research is needed on the provision of MPASI    

Sea urchin (Diadema setosum) is an aquatic biota that has high nutritional value. Bioactive compounds produced by sea urchins have the potential to be used as natural antibacterial compounds.

The research method used is the agar diffusion method. The results of phytochemical screening of sea urchin extract (Diadema setosum) showed the presence of alkaloids and saponins. By using variations in the concentration of ethanol extract of sea urchin (Diadema setosum) at a concentration of 80% it had an inhibitory power of 18 mm, a concentration of 90% had an inhibitory power of 23 mm, a concentration of 100% had an inhibitory power of 28 mm and for a concentration of 110% had an inhibitory power of 35 mm. The positive control has a resistance of 30 mm and the negative control is 0 mm. The results showed that the ethanol extract of sea urchins (Diadema setosum) had a strong bacterial inhibitory activity against Staphylococcus aureus bacteria.

Monitoring nutrition and health during the First 1000 Days of Life (HPK) in Pacellekang Village is very important to prevent stunting. However, during the pandemic, many posyandu were forced to stop their activities because they were in the red zone. The assistance program for malnourished pregnant women (KEK) aims to improve the health and nutritional status of KEK pregnant women in Makassar City. Community service activities are carried out online using Zoom meetings, WhatsApp groups and Google Forms. The results of the service show that most of the knowledge and attitudes of pregnant women regarding nutrition and health are classified as good. The majority (85.2%) of pregnant women had carried out pregnancy checks at least four times with a midwife or doctor during pregnancy. Apart from that, 88.9% of pregnant women regularly take blood supplement tablets. Around 85.2% of pregnant women follow the principles of balanced nutrition in their daily diet. However, 55.6% of pregnant women who frequently experience nausea and vomiting tend to lose their appetite and skip meals and snacks. Based on program monitoring in October, there were records that two pregnant women were unable to provide exclusive breastfeeding (IMD) due to premature birth (separation care), and young mothers (under 20 years) felt anxious when breast milk did not come immediately after delivery, so they gave Formula milk.    

Background: The maternal mortality rate (MMR) in Indonesia is still quite high,based on the results of SUPAS in 2015, the MMR was 305/ 100,000 live births.Efforts to decrease of MMR can be done by ensuring that every mother can access quality health services for pregnant women because every pregnancy has the risk of complications. Integrated antenatal services are carried out including health counseling, antenatal care, case management and follow-up, preparation for delivery and planning for referrals in case of pregnancy. In the initial researchconducted in Hutaginjang Village, Muara, there were still pregnant women who did not have their pregnancy checked according to the minimum pregnancy standards. Purpose: Screening and pregnancy risk factors is indispensable for early pregnancy and the potential for emergency pregnancy. Methods: Activities carried out by integrated and free pregnancy examinations for pregnant women include measuring weight / height and arm  ircumference, vital signs, physical examination, Hb examination, urine protein and glucose, provision of IEC about nutritional fulfillment, overcoming complaints of pregnant women in trimester IIII,preparation for delivery and administration of iron supplements as well as preparation for referrals for mothers who experience complications in their pregnancy. Results: The activity was carried out without any obstacles, with 18 mothers having their pregnancies checked. The results of the examination found several risk factors for pregnancy, namely age under 20 years and above 35 years of parity, history of delivery by sectio, height below 145 cm, anemia,preeclampsia, breech location, hyperemesia gravidarum, gestational diabetes and gemelli pregnancy. Each mother received communication, information and education related to  maintaining and improving health during pregnancy and  giving iron tablets. Conclusion:Screening and control of pregnancy risk factors is needed to detect early whether the pregnancy is at risk and has the potential for emergency pregnancy, so that the mother can pass her pregnancy well and give birth to a healthy baby.   

Iron (Fe) tablets are mineral tablets that the body uses to make red blood cells and hemoglobin. For red blood cell production, Fe is the most significant element. Food is a natural source of iron. Nutritional anemia can develop in pregnant women if they don't get enough iron in their diet (blood deficiency). Pregnant women need iron (Fe) tablets, so they must consume at least 90 Fe tablets during pregnancy. The aim of the research was to determine the relationship between consumption of Fe tablets and the incidence of anemia at the Penrang Community Health Center, Wajo Regency. The type of research used was a cross sectional study. The samples were 72 pregnant women who underwent pregnancy checks at the Penrang Community Health Center, Wajo Regency, using a random sampling technique. The research results showed a relationship between consumption of Fe tablets and the incidence of anemia at the Penrang Health Center, Wajo Regency, where the p value = 0.000 < ? = 0.05. The conclusion is that there is a relationship between the consumption of Fe tablets and the incidence of anemia at the Penrang Community Health Center, Wajo Regency.

Infant health can be known one of them through the assessment of nutritional status. In general, Body Mass Index (BMI) has been used as a method for measuring the nutritional status of children. If there are two children who have same body weight and height, they may have different nutritional status. Whenever this occurs, the use of BMI for measuring the nutritional status shall be deemed less accurate. The anthropometry will be vital in measuring the nutritional statuss. The guidelines for determining the nutritional status Anthropometry parameters are selected and recommended which includes an assessment of the age, weight, body length or height. This research aims to build a model of C4.5 adaboost so it can recognize patterns and be able to classify the nutritional status of children into five classes: normal, fat, very fat, thin and very thin. The variables used in this classification is Gender, Age (Months), Weight (kg) Height (cm). C4.5 (decision tree) Method has a good performance in dealing with the classification of nutritional status but the C4.5 has a weakness in the class imbalance. Adaboost isone ofboosting methods that could reduce imbalances class by giving weight to the level of classification error which may alter the distribution of data. Experiments carried out by applying the adaboost method C4.5 to obtain optimal results and a good degree of accuracy. The experimental results obtained from C4.5 method show that accuracy is 89.53%, the error rate is 10.47%, while the results of C4.5 with adaboost show 90.23% accuracy and 9.77% error rate. It can be concluded in the classification of nutritional status of children with C4.5 and adaboost proven method to solve problems of class imbalance and improve the high accuracy and can reduce the level of classification error.

The increase in Life Expectancy (UHH) has an impact on the increase in the elderly population and the problems due to aging. One of them is the system for regulating blood sugar levels which is disrupted due to changes in the body composition of the elderly in the form of increased fat composition from the body 14% to 30%. Efforts to prevent the incidence of Diabetes Mellitus is to achieve good nutritional status with anthropometric measurements, namely the division of body weight in kg with height in meters squared expressed in body mass index or BMI. This study aims to analyze the relationship between BMI and blood sugar levels in the elderly at the Sabar Narimo Posyandu, Lempuyangan Hamlet, Gebugan Village, Bergas District, Semarang Regency. The research design used was descriptive observational with a cross sectional approach. The number of samples was 40 elderly who were taken by purposive sampling technique. The instrument used to measure BMI is a digital weight scale, and a microtoise that has been calibrated, while blood sugar levels are measured using a glucometer. Data were analyzed by Pearson Corellation test. The results of this study indicate the frequency distribution of blood sugar levels in the elderly at the Posyandu Sabar Narimo on average 139.92 mg/dl and an average BMI of 25.24 kg/m2. The results showed that BMI was related to the variable of blood sugar levels with a correlation coefficient (r) of 0.614 and a significance value (?) of 0.0234 then there is a relationship. The conclusion in this study is that there is a relationship between blood sugar and BMI in the elderly at the Sabar Narimo Posyandu, Lempuyangan Hamlet, Gebugan Village, Bergas District, Semarang Regency.
