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: The Effect of Nutrition Education through Nutri-c Media and Lecture Methods on Knowledge and Attitudes of Balanced Nutrition in Elementary School Students
Abstrak: Pendidikan gizi seimbang menjadi salah satu upaya untuk meningkatkan penerapan Pedoman Gizi Seimbang (PGS) pada anak usia sekolah. Penelitian ini bertujuan menganalisis pengaruh pemberian pendidikan gizi seimbang melalui media nutri-c terhadap pengetahuan dan sikap gizi siswa sekolah dasar. Penelitian ini menggunakan desain quasi experimental yang dilaksanakan pada bulan Maret-Mei 2023 di SDN Ciherang 04, Kabupaten Bogor. Subjek merupakan siswa kelas 5 SD dengan jumlah 44 orang yang dipilih secara purposive dan dibagi ke dalam dua kelompok penelitian. Kelompok intervensi 1 mendapatkan intervensi menggunakan media nutri-c sedangkan kelompok intervensi 2 menggunakan metode ceramah. Hasil uji beda Wilcoxon menunjukkan terdapat perbedaan pengetahuan gizi seimbang yang signifikan setelah intervensi pada kelompok intervensi 1 (p=0,000). Tidak terdapat perbedaan yang signifikan terkait sikap gizi seimbang setelah intervensi pada kelompok intervensi 1 (p=0,063). Perbedaan pengetahuan (p=0,000) dan sikap (p=0,002) gizi seimbang sebelum dan setelah intervensi pada kelompok intervensi 2 menunjukkan hasil yang signifikan. Media nutri-c lebih efektif meningkatkan pengetahuan subjek. Hasil uji beda Mann Whitney U menunjukkan tidak terdapat perbedaan yang signifikan terkait pengetahuan (p=0,924) dan sikap (p=0,212) gizi seimbang antara kelompok penelitian. Tidak terdapat hubungan yang signifikan antara pengetahuan dengan sikap gizi seimbang subjek setelah mendapatkan intervensi berdasarkan hasil uji korelasi Spearman (p<0,05)., Balanced nutrition education is one of the efforts to improve the implementation of Balanced Nutrition Guidelines (PGS) for school-age children. This study aimed to analyze the effect of providing balanced nutrition education through nutri-c media on the nutritional knowledge and attitudes of elementary school students. This study used a quasi-experimental design which was conducted from March to May 2023 at SDN Ciherang 04, Bogor Regency. The subjects were 5th grade elementary school students with a total of 44 people selected purposively and divided into two research groups. The intervention group 1 received intervention using nutri-c media while the intervention group 2 used the lecture method. The results of the Wilcoxon differential test showed that there were significant differences in knowledge of balanced nutrition after the intervention in the intervention group 1 (p=0.000). There was no significant difference regarding the attitude of balanced nutrition after the intervention in the intervention group 1 (p=0.063). Differences in knowledge (p=0.000) and attitudes (p=0.002) about balanced nutrition before and after the intervention in the intervention group 2 showed significant results. Nutri-c media is more effective in increasing subject knowledge. The results of the Mann Whitney U test showed that there were no significant differences in knowledge (p=0.924) and attitude (p=0.212) to balanced nutrition between the study groups. There was no significant relationship between knowledge and balanced nutrition attitudes of the subjects after receiving the intervention based on the results of Spearman's correlation test (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.
