Abstract

Stunting is a health problem due to insufficient nutritional intake during the first thousand days of life (HPK). One of the causes of stunting in Lampung Province is not optimal balanced nutritional intake and low coverage of Stimulation for Early Detection and Intervention of Growth and Development in Toddlers. North Lampung Regency is one of the six stunting locus districts in Lampung Province. The high stunting rate and low SDIDTK coverage in North Lampung Regency are caused by the low nutritional intake of toddlers and the lack of knowledge of cadres and mothers of toddlers about SDIDTK. This community service activity aims to empower the community (health cadres) to optimize the growth and development of toddlers by using the KIA Book and essential nutrition during the Golden Age Period. The community service activity method uses a process approach starting from planning, implementation, and evaluation which is carried out intercollaborative. Activities include specific promotive and preventive efforts to increase SDIDTK coverage and the nutritional status of children under five. The results of this activity increased the understanding of Posyandu cadres in monitoring the growth and development of toddlers, the existence of Posyandu cadres' efforts to overcome nutritional problems for toddlers, and good use of yard land by families to support food security.

Abstract

The number of elderly tends to increase every year. An increase in the number of elderly is also usually followed by physical, mental, spiritual, economic and social changes. The aging process has an impact on a decrease in physical, mental, psychosocial conditions, changes related to work and the social role of the elderly. Problems in the elderly can cause stress which is characterized by feelings of uselessness, not needed and feelings of being left out. This situation has the potential to cause problems in the elderly, one of which is low self-esteem. The aim of the study was to determine the effect of reminiscence therapy on the self-esteem of the elderly at the UPTD Tresna Werdha Natar Elderly Social Services. This study used a quantitative method with a quasi-experimental design with a pre-post test without a control group using a purposive sampling technique and a random sampling method with a total sample of 30 respondents. The samples taken were the elderly who experienced low self-esteem with a score <15. The researcher used the Rosenberg Self Esteem Scale (RSES) questionnaire to measure the self-esteem of the elderly. The results showed that after being given reminiscence therapy in the elderly there was an increase in self-esteem. Nurses are expected to be able to provide reminiscence therapy to the elderly who experience low self-esteem.

Abstract

Diseases transmitted by mosquitoes are diseases that have a high risk of mortality and morbidity. One of the efforts to overcome the mosquito life cycle is by giving larvicides. The use of natural larvicides can be a safer alternative for health. Plants that have the potential as natural larvicides to kill mosquito larvae are papaya leaves (Carica Papaya). This study aims to determine the effect of giving powdered papaya california (Carica Papaya) leaves to the mortality of mosquito larvae. This research is a quantitative research with Intac Group Comparison research design. The research instrument used an observation sheet. Purposive sampling with a total of 50 samples were grouped into 4 treatment groups with a dose of 60 mg, 150 mg, 300 mg, 500 mg and 1 control group. Data analysis in the form of univariate analysis and using Wilcoxon statistical test. The lowest larval mortality was at a dose of 60 mg (10%) and the highest mortality was at a dose of 500 mg (60%). The results of the analysis in the 60 mg, 150 mg and 300 mg treatment groups obtained p-value > 0.05 so that there was no significant difference between the 60 mg, 150 mg, and 300 mg papaya leaf powder treatment groups and the control group. The 500 mg group had a p-value of 0.011 <0.05, so it can be concluded that there was a significant difference between the treatment group with 500 mg papaya leaf powder and the control group. Giving papaya leaf powder with a concentration of 500 mg has an effect on the mortality of mosquito larvae.

Abstract This development research aims to determine the results of the development of Adobe Flash as a medium for learning the Pythagorean theorem for class VIII SMP. The product resulting from this research is in the form of learning media on Pythagorean theorem material with several sub-discussions, namely using the Pythagorean theorem to calculate the length of one side of a triangle if the other two sides are known, calculating the ratio of sides in a right triangle with angles of 300 and 600, and calculating the ratio of the sides of a right triangle with an angle of 450. The development model used in this study refers to the model developed by Sivasailam Thiagarajan, Dorothy S. Semmel, and Melvyn I. Semmel in 1974, namely the 4D model. This model consists of four stages of development namely define, design, develop, and disseminate or abbreviated as 4D. The results of this development research were obtained as follows: First, the validation stage by 3 expert validators covering aspects of programming, content (material), and display obtained an average expert validation result of 4.19 indicating that learning media (products) are in the "valid" category. ”. Second, the trial phase is limited to students' responses to learning media and an average result of 89.167% is obtained which indicates that the learning media (product) is in the "very good" category. Third, the field test stage on average students gave a response of 87% indicating that the learning media (product) was in the "very good" category. The average pre-test result was 76.25 while the post-test average result was 86.27. There is a significant difference between the average results of the pre-test and post-test data. This result is reinforced by the results of the calculation of the related sample t-test with SPSS 16 software, the value of Sig. (2-tailed) = 0.000 < 0.05 = ????. Based on the results obtained from the stages that have been taken, it shows that the use of product development is "effective" in learning mathematics on the Pythagorean theorem material for class VIII students at SMPN 2 Labuapi
