Judul: Tingkat Literasi Gizi Generasi Milenial Tahun 2020
Abstrak: Penelitian ini merupakan studi cross sectional bertujuan menganalisis literasi gizi generasi milenial dan faktor yang berhubungan dengannya. Subjek berjumlah 234 orang dipilih melalui snowball sampling. Pengumpulan data dilakukan melalui kuesioner online meliputi karakteristik individu dan sosial ekonomi keluarga, media informasi terkait kesehatan, pangan, dan gizi, serta literasi gizi. Lebih dari separuh subjek (62,4%) menyukai informasi berbentuk audio visual dan 42,3% lebih menyukai secara online. Sumber informasi yang paling dipercaya adalah profesional kesehatan, sedangkan yang paling tidak dipercaya adalah teman non tenaga kesehatan. Rata-rata frekuensi mencari informasi 83,3% subjek tergolong jarang dan rata-rata durasi 70,1% subjek terbanyak 1-30 menit. Sebanyak 75,2% subjek cukup percaya diri dan 18,4% sangat percaya diri dalam mencari informasi. Hambatan terbanyak dalam mencari informasi adalah 49,6% khawatir dengan kualitas informasi yang didapat dan 31,6% malas mencari tahu. Tingkat literasi gizi hampir tiga perempat (72,2%) subjek berada pada kategori kurang dan cukup, hanya seperempat (27,8%) subjek pada kategori baik. Uji korelasi Spearman menunjukkan literasi gizi subjek berhubungan signifikan positif (p<0,05) dengan latar belakang pendidikan kesehatan, latar belakang pendidikan gizi, besarnya pendapatan/ uang saku, frekuensi penggunaan media, dan kepercayaan diri, namun tidak berhubungan dengan karakteristik individu lainnya, karakteristik keluarga, durasi penggunaan media, dan hambatan dalam memperoleh informasi. Kata kunci: generasi milenial, literasi gizi, sumber informasi, This cross sectional study aimed to analyze nutrition literacy among millennial generation and factors associated. It involved 234 subjects, selected through snowball sampling. Data was collected through an online questionnaire covering individual and family socio-economic characteristics, information media related to health, food and nutrition, and nutrition literacy. More than half of the subjects (62.4%) liked audio-visual information and 42.3% preferred it online. The most trusted source of information were health professionals while the reverse were non health professionals friends. The average frequency of seeking information for the majority can be considered rare with the longest duration of 1-30 minutes. More than a third of the subjects 75.2% are quite confident and 18.4% are very confident in seeking information. The most obstacle to finding information are worrying about the quality of the information obtained (49.6%) and laziness to find out whether they are true (31.6%). Almost three fourth (72.4%) subjects had nutrition literacy level ranging from low to sufficient level, while only one fourth (27.8%) subject classify as good nutrition literacy. The Spearman correlation test showed a positive significant relationship (p<0.05) between nutrition literacy and health education background, nutrition education background, income, frequency of media access and self-confidence, but not related to other individual and family socio-economic characteristics, duration of media use, and barriers to obtaining information.

Judul: The Correlation between Nutritional Knowledge, Eating Habits, and Physical Activity with Nutritional Status among Student of SMAN 1 Kebumen
Abstrak: Prevalensi remaja gemuk usia 16-18 tahun di Indonesia meningkat pada tahun 2018. Kegemukan pada remaja dapat menimbulkan dampak negatif terkait aspek kesehatan dan psikososial. Penelitian ini bertujuan menganalisis hubungan pengetahuan gizi dengan kebiasaan makan, hubungan kebiasaan makan dengan status gizi, dan hubungan aktivitas fisik dengan status gizi siswa SMAN 1 Kebumen. Penelitian dilakukan pada Mei 2023 menggunakan desain cross sectional, melibatkan 30 remaja normal dan 30 remaja gemuk yang dipilih secara purposive. Data primer diperoleh melalui pengisian kuesioner dan wawancara berupa data karakteristik individu, karakteristik keluarga, pengetahuan gizi, aktivitas fisik, dan kebiasaan makan. Hasil uji beda menunjukkan tidak terdapat perbedaan signifikan (p>0,05) pengetahuan gizi, aktivitas fisik dan duduk, tingkat kecukupan energi dan zat gizi, asupan gula, serta kebiasaan pangan sumber gula dan lemak antara kedua kelompok subjek, namun kelompok subjek gemuk signifikan lebih banyak asupan lemaknya (p<0,05). Hasil uji korelasi menunjukkan hubungan signifikan positif antara asupan lemak dengan status gizi (p=0,01). Tidak terdapat hubungan signifikan pengetahuan gizi dengan kebiasaan pangan sumber gula dan lemak, asupan gula dan lemak, serta tingkat kecukupan energi dan zat gizi. Tidak terdapat perbedaan signifikan kebiasaan pangan sumber gula dan lemak, asupan gula, tingkat kecukupan energi dan zat gizi, dan aktivitas fisik dengan status gizi (p>0,05)., Prevalence obese adolescents aged 16-18 years in Indonesia increased in 2018. Obesity in adolescents have negative impacts related to health and psychosocial. This study aims to analyze correlation nutritional knowledge and eating habits, correlation eating habits and nutritional status, and correlation physical activity and nutritional status students at SMAN 1 Kebumen. Study was conducted in May 2023 using a cross-sectional design, involving 30 normal and 30 obese adolescents that selected purposively. Primary data was obtained through questionnaires and interviews with individual characteristics, family characteristics, nutritional knowledge, physical activity, and eating habits. There was no significant difference (p>0.05) nutritional knowledge, physical activity and duration of sitting, energy and nutrients adequacy level, sugar intake, and eating habits of food sources sugar and fat between two subject, but obese subjects had significantly higher fat intake (p<0.05). There was a significant positive correlation fat intake and nutritional status (p=0.01). There was no significant correlation nutritional knowledge with eating habits of food sources sugar and fat, intake sugar and fat, also energy and nutrients adequacy level (p>0.05). There was no significant correlation eating habits of food sources sugar and fat, sugar intake, energy and nutrients adequacy level, and physical activity with nutritional status (p >0.05).

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
