Teenagers are a group of ranges experiencing nutritional problems. Nutrition problems that often occur in adolescents are lack of nutrient intake which can trigger chronic energy deficiency (CED) and anemia as a result of iron deficiency. The purpose of the study was to analyze the relationship of macro nutrient intake, iron intake, hemoglobin levels to the risk of chronic energy deficiency. This study uses a case-control design, which was carried out on 72 Muhammadiyah 1 Palembang high school students consisting of 36 at risk of CED and 36 at no risk of CED. Data on macro-nutrient intake and Fe intake were obtained from the calculation of Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), Hemoglobin content data using the quick check method, and CED data through measurement of mid-upper arm circumference (MUAC). Data analysis using the Chi-square test at CI:95%. The results showed that there was a significant relationship between energy consumption and macronutrient intake (p=0,004), protein (p=0,004), fat (p=0,031), and iron intake (p=0,000) with the risk of young female CED. The absorption of macro and micronutrients influences. The conclusion, the risk of CED in adolescent girls. Suggestions, education and interventions need to be done related to the importance of paying attention to the nutritional status of adolescent girls. Remaja merupakan kelompok rentang mengalami masalah gizi. Masalah gizi yang sering terjadi pada remaja adalah kurangnya asupan zat gizi yang dapat memicu terjadinya kurang energi kronis (KEK) serta anemia sebagai akibat kekurangan zat besi. Tujuan penelitian untuk menganalisis hubungan asupan zat gizi makro, asupan zat besi, kadar haemoglobin terhadap risiko kurang energi kronis. Metode penelitian survei analitik dengan desain secara kasus kontrol. Penelitian dilakukan pada 72 siswi SMA Muhammadiyah 1 Palembang terdiri 36 berisiko KEK dan 36 tidak KEK.  Data asupan zat gizi makro dan asupan Fe diperoleh dari perhitungan Semi Quantitative Food Frequency Questionnaire (SQ-FFQ), data kadar Haemoglobin menggunakan metode quick cek, dan data KEK melalui pengukuran lingkar lengan atas (LiLA). Analisis data menggunakan uji Chi-square pada CI:95%. Hasil penelitian menunjukkan terdapat hubungan signifikan antara asupan z\at gizi makro energi (p=0,004), protein (p=0,004), lemak (p=0,031) dan asupan zat besi (p=0,000) dengan risiko KEK remaja putri. Kesimpulan, Risiko KEK pada remaja putri dipengaruhi oleh asupan zat gizi makro dan mikro. Saran, perlu dilakukan edukasi dan intervensi terkait pentingnya memperhatikan status gizi remaja putri.

Penelitian ini bertujuan untuk mengetahui saluran pemasaran yang paling efisien yang digunakan oleh petani karet di lokasi penelitian dan untuk mengetahui besarnya nilai keuntungan masing-masing lembaga pemasaran pada setiap saluran pemasaran. Metode penelitian untuk melihat efisiensi pemasaran digunakan analisis margin pemasaran, farmer’s share, dan Profitability Index.

The importance of understanding mindsets to direct behavior in internet-based entrepreneurship is the effort in bringing entrepreneurial learning processes close to changes in entrepreneurial behavior. This study aims to determine the grouping of students’ mind sets in two growth and fixed categories, knowing the description of mind set content and internet entrepreneurial behavior in students, knowing the differences in internet entrepreneurial behavior based on student mindsets, knowing the correlation between mind set and internet entrepreneurial behavior, then know the contribution of mindset to internet entrepreneurial behavior. This research method with a quantitative approach, using a likert scale questionnaire instrument, the sample is students registered at UPI YPTK Padang in 2018/2019 academic year totaling 148 people, sampling from the population is done by purposive sampling technique, data analysis with percentage techniques in describing data, independent test sample t test for different tests, pearson correlation product moment analysis for testing the relationship of variables and the square of r for testing the contribution. The results of the analysis state that 45% of students with a fixed mind set and 55% with a growth mind set, students with a growth mind set have better internet entrepreneurial behavior with an average of 86.82%. Hypothesis testing states that there are differences in student internet entrepreneurial behavior based on personal mindsets, there is a fairly strong correlation between mind set with internet entrepreneurial behavior, with a contribution of 20.4%. It is proven that students with growth mindsets have higher behavior in internet entrepreneurial activities, therefore to increase the ability and interest of students in entrepreneurship must start from the approach to the correct mindset about entrepreneurship.

The aim of this research is to chemically modify chitosan to improve and enhance the ability as an adsorbent. Chitosan is a natural polymer produced from chitin deacetylation. The best performance of chitosan is as an adsorbent is in acidic solutions. Chemical modification was carried out by chitosan copolymerization with acrylamide. Copolymer synthesis was done by using microwave oven with the weight ratio of chitosan and acrylamide of 1: 4. The characterization of chitosan copolymer with acrylamide (chitosan-g-acrylamide copolymer) was conducted by FTIR spectroscopy and Scanning Electron Microscope (SEM). The analysis of the functional group by FTIR spectroscopy shows that the copolymer has been successfully synthesized. The surface analysis with SEM shows that the morphology of the copolymer surface is more homogeneous compared to that of chitosan.
