Judul: The Effect of Low Carbon Diet Education on Food Consumption, Nutritional Intake, and Carbon Emission in IPB Students
Abstrak: Permasalahan gizi di Indonesia terus meningkat sebagai konsekuensi dari pola konsumsi pangan yang kurang baik. Di sisi lain, sistem pangan merupakan salah satu kontributor utama peningkatan emisi gas rumah kaca (GRK), yaitu sebesar 33% dari total emisi GRK. Penerapan diet rendah emisi karbon diperlukan untuk kesehatan masyarakat dan kelestarian lingkungan. Penelitian ini bertujuan (1) menganalisis perubahan pengetahuan dan sikap responden pre- dan post- intervensi; (2) menganalisis perubahan proporsi konsumsi dan tingkat kecukupan gizi responden pre- dan post- intervensi; (3) menganalisis perubahan emisi karbon konsumsi pangan responden pre- dan post- intervensi; serta (4) menganalisis hubungan karakteristik individu dan keluarga dengan perubahan pengetahuan, sikap, dan konsumsi responden. Metode yang digunakan adalah quasi- experimental with pre- and post-test design melalui intervensi pendidikan dengan rancangan same subject design. Edukasi low carbon diet pada mahasiswa IPB dapat meningkatkan pengetahuan dan sikap secara signifikan. Edukasi ini tidak berpengaruh pada proporsi konsumsi dan tingkat kecukupan gizi responden, kecuali tingkat kecukupan vitamin D dan fosfor yang menurun signifikan. Intervensi yang dilakukan belum bisa menurunkan emisi karbon secara signifikan. Karakteristik individu dan keluarga tidak berhubungan dengan perubahan pengetahuan, sikap, dan konsumsi responden setelah intervensi., Triple burden malnutrition in Indonesia continues to increase as a consequence of poor diaetary patterns. On the other hand, food systems, are one of the main contributors to the increase in greenhouse gas emissions (GHG-E), accounting to 33% of GHG-E global. Implementation of low carbon diet is needed for public health and environmental sustainability. This study aims to (1) Analyze changes in respondents’s knowledge and attitudes at pre- and post- intervention; (2) Analyze changes in the respondents’ consumption and nutritional adequacy level at pre- and post- intervention; (3) Analyze changes in the respondents’ food carbon footprint at pre- and post- intervention; and (4) Analyze the relationship of respondents and family characteristics with respondents’s changes in knowledge, attitudes, and the food consumption. The method used is a quasi-experimental with pre- and post-test design through educational intervention with the same subject design. Low carbon diet education for IPB students can significantly increase their knowledge and attitudes. The education did not cause significant differences in the respondents’ consumption and nutritional adequacy level, except significantly decreased of vitamin D and phosphorus adequacy level. The intervention has not been able to reduce carbon emissions. In addition, respondents and family characteristics unrelated to changes in respondents' knowledge, attitudes, and consumption after the intervention.

Judul: Nutritional Knowledge, Eating Habits and Lifestyle  Change, with Nutritional Status of IPB University Student During Covid-19  Pandemic
Abstrak: Pandemi Covid-19 mengakibatkan perubahan kebiasaan makan dan gaya hidup. Perubahan terjadi karena pembelajaran daring dari rumah dan meningkatnya kesadaran hidup lebih sehat. Ilmu kesehatan erat kaitannya dengan kurikulum gizi, sehingga mahasiswa gizi diharapkan dapat menerapkan ilmu tersebut di kehidupan sehari-hari. Tujuan penelitian yaitu menganalisis hubungan pengetahuan gizi, perubahan kebiasaan makan dan gaya hidup, dengan status gizi mahasiswa IPB saat pandemi Covid-19. Desain penelitian cross sectional study yang dilaksanakan pada bulan April sampai Juli 2021. Data primer diperoleh dari pengisian kuesioner, wawancara, dan self report data antropometri. Hasil penelitian menunjukkan sebagian besar subjek berstatus gizi normal (54,7%). Tingkat pengetahuan gizi subjek tergolong baik dan cukup dengan rata-rata skor 82,5. Persentase perubahan kebiasaan makan terbesar terjadi pada peningkatan konsumsi buah dan sayur (66,7%). Persentase perubahan gaya hidup terbesar terjadi pada kebiasaan pemakaian masker setiap beraktivitas diluar rumah (94,7%). Hasil uji korelasi Spearman menunjukkan tidak terdapat hubungan yang signifikan (p value>0,05) antara skor pengetahuan gizi, skor perubahan kebiasaan makan, dan skor perubahan gaya hidup dengan Indeks Massa Tubuh (IMT)., Covid-19 pandemic impact to eating habits and lifestyle changes. Its occured due to online learning from home and the increasing of health awareness. Health science closely related to the nutrition curriculum, therefore nutrition student are expected to imply their knowledge in daily life. The aim of this research is to analyze the relation of nutritional knowledge, changes in eating habits and lifestyle to nutritional status of IPB University students during the pandemic. This research design was a cross sectional study that carried out from April until July 2021. Primary data obtained by filling out questionnaires, interview, and self reporting anthropometric data. The results of this research showed that most of the subject had normal nutritional status (54,7%). The level of subject nutritional knowledge is good and adequate with average score 82,5. The largest percentage of changes in eating habits is the increase of fruit and vegetable consumption (66,7%). The largest percentage of changes in lifestyle is the increase of wearing masks habit everytime the subject go outside (94,7%). The results of Spearman correlation test showed that was no significant relationship (p value>0,05) between score of nutritional knowledge, eating habit, and lifestyle changes with the Body Mass Index (BMI).

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.
