Combining high biodiversity with high yields in tropical agroforests.

Local and landscape-scale agricultural intensification is a major driver of global biodiversity loss. Controversially discussed solutions include wildlife-friendly farming or combining high-intensity farming with land-sparing for nature. Here, we integrate biodiversity and crop productivity data for smallholder cacao in Indonesia to exemplify for tropical agroforests that there is little relationship between yield and biodiversity under current management, opening substantial opportunities for wildlife-friendly management. Species richness of trees, fungi, invertebrates, and vertebrates did not decrease with yield. Moderate shade, adequate labor, and input level can be combined with a complex habitat structure to provide high biodiversity as well as high yields. Although livelihood impacts are held up as a major obstacle for wildlife-friendly farming in the tropics, our results suggest that in some situations, agroforests can be designed to optimize both biodiversity and crop production benefits without adding pressure to convert natural habitat to farmland.

The influence of fluoride in drinking water on the incidence of fluorosis and intelligence of elementary school students in Palu City.

OBJECTIVE: This research aims to know the influence of fluoride in drinking water towards Fluorosis and the Intelligence Level of Elementary School Students in Palu City. METHOD: This cross-sectional study was performed through descriptive analysis on 100 students aged 6-12 years old selected by stratified random sampling from two different areas with different levels of fluoride in drinking water in Palu City. The samples were collected from two different elementary schools which were SDN 2 Talise and SDN Inpres 1 Birobuli. The examination was performed by a dentist using Dean's Fluorosis Index and philology, who measured students' IQ using Raven's Coloured Progressive Matrices. RESULTS: High level of F in drinking water affects the fluorosis status of students (p=0.001), in which among 40 students (40%) who experienced fluorosis, 38 (38%) of them are from the area whose F level is high. The high level of F also affected the children's IQ, obtaining a p-value of 0.001, showing that there were no students with low IQ found in the area with low F level. For the status of Fluorosis and IQ, p=0.001 was obtained. Among the 60 students who did not experience fluorosis, 96.6% of them had a high IQ level. CONCLUSION: The recent research found that fluorosis was found more often in the area of which F level was high, where the IQ level of the students was found to be lower compared to the students who loved in the area with low F level.

The relationship between knowledge and personal hygiene and the occurrence of sexually transmitted diseases at the Community Health Center Talise, Palu.

OBJECTIVE: This morbidity rate has increased compared to the results of a survey in 2012, which were 16,110 cases of STDs, and 11,141 cases in 2010. This study aimed at determining the relationship between knowledge and personal hygiene and the incidence of sexually transmitted diseases in adolescents at the Community Health Center Talise, Palu. METHODS: This study utilized a case-control study design to assess the relationship between knowledge and personal hygiene and the occurrence of sexually transmitted diseases. There were 84 samples in this study involving 42 cases and 42 controls. Data collection was carried out using a questionnaire. RESULT: The variable of personal hygiene showed that the Chi-Square test results provided a value of p=0.016, which means that the difference between individual hygiene and the incidence of sexually transmitted diseases (STDs) in adolescents was significant (p<0.05). CONCLUSION: This study concludes that the OR calculation has a value of 4.6, which means that adolescents who have insufficient knowledge have 4.6 times greater risk of suffering from STDs than adolescents who had sufficient knowledge.

The effect of oxytocin massage and breast care on the increased production of breast milk of breastfeeding mothers in the working area of the public health center of Lawanga of Poso District.

OBJECTIVE: The objective of this research is to know the effect of oxytocin massage and breast care on the increase of breast milk production. METHOD: This pre-experimental research was performed through the One Group Pretest-Posttest design. The sampling was done through non-probability sampling and purposive sampling, obtaining 30 samples. The data were collected in the form of a questionnaire, which was then analyzed using the Mc Nemar test. RESULT: It was known that the production of breast milk during pre-intervention was poor on 18 respondents and adequately a lot on the other 12 respondents. Meanwhile, during the post-intervention, the production of breast milk on the 18 respondents whose previously breast milk production was poor then become adequate on the seven respondents, while the remaining 11 respondents still produced less breast milk. The statistical test result showed a P value of 0.016, which means that the P is less than 0.05. CONCLUSION: Oxytocin massage and breast care affected the increase of breast milk production considered based on the frequency and duration of breastfeeding as well as the infants' weight in Lawanga Public Health Center, Poso District.
