Judul: Intervention of Seaweed Rice and Level of Physical Activity on Blood Glucose Levels in Prediabetes and Diabetic Patients
Abstrak: Salah satu faktor yang berperan dalam peningkatan angka kejadian Diabetes Melitus (DM) adalah gaya hidup. Upaya yang dapat dilakukan agar mencegah jumlah penderita DM adalah dengan melakukan terapi gizi dan aktivitas fisik. Nasi rumput laut dapat menjadi alternatif sebagai pangan fungsional bagi penderita DM karena memberikan pengaruh penurunan kadar glukosa darah pada tikus uji coba. Penelitian ini bertujuan menganalisis pengaruh intervensi nasi rumput laut dan tingkat aktivitas fisik terhadap kadar glukosa darah pada penderita prediabetes dan DM tipe 2. Penelitian ini berbasis desain quasi experimental dengan rancangan prepost with control yang dilakukan pada akhir bulan Desember 2021 dan dilakukan selama 42 hari masa penelitian. Berdasarkan uji Mann Whitney, selisih penurunan kadar GDP kelompok intervensi tidak berbeda secara nyata dengan kelompok kontrol (p>0,05) meskipun terdapat penurunan kadar GDP. Hasil uji Mann Whitney menunjukkan aktivitas fisik berhubungan signifikan terbalik dengan kadar GDP (p<0.05). Berdasarkan penelitian yang dilakukan, intervensi konsumsi nasi rumput laut dan tingkat aktivitas fisik menurunkan kadar glukosa darah., One of the factors that played a role in increasing the incidence of Diabetes Mellitus (DM) is lifestyle. Efforts that can be made to prevent the number of people with DM are by doing nutritional therapy and physical activity. Seaweed rice could be an alternative as a functional food for DM sufferers because had the effect of reducing blood glucose levels in experimental rats. This study aims to analyze the effect of the seaweed rice intervention and the level of physical activity on blood glucose levels in patients with prediabetes and DM type 2. This study was based on a quasi-experimental design with a pre-post with control design which was conducted at the end of December 2021 and was conducted for 42 days research period. Based on the Mann Whitney test, the difference in GDP levels in the intervention group was not significantly different from the control group (p>0.05) even though there was a decrease in GDP levels. The results of the Mann Whitney test showed that physical activity had an inversely significant relationship with GDP levels (p<0.05). Based on research conducted, the intervention of consuming seaweed rice and physical activity levels lowered blood glucose levels.

Judul: Effect of Seaweed Noodle Intervention on Fiber Intake,  Blood Glucose, and Nutritional Status of People with Hyperglycemia
Abstrak: Hiperglikemia adalah kondisi medis yang ditandai oleh peningkatan kadar glukosa darah di atas normal dan sering terkait dengan diabetes mellitus. Mie rumput laut merupakan produk pangan berbahan dasar tepung sagu dan tepung rumput laut yang bertujuan untuk mencegah hiperglikemia. Penelitian ini bertujuan untuk mengetahui pengaruh intervensi mi rumput laut terhadap asupan zat gizi, glukosa darah, dan status gizi penderita hipergikemia. Penelitian ini menggunakan desain randomized clinical trial dengan rancangan pre-mid-post with control yang dilakukan selama 42 hari pada Desember 2023 – Januari 2024. Intervensi pada penelitian ini memberikan pengaruh signifikan terhadap konsumsi serat (p=0,007), konsumsi karbohidrat (p=0,046), frekuensi konsumsi buah-buahan (p=0,015), dan glukosa darah puasa (p=0,027). Intervensi ini menurunkan kadar glukosa darah pada kelompok intervensi (-23 mg/dL ±28 mg/dL) dan kelompok kontrol (-1 mg/dL ± 20 mg/dL), dengan penurunan lebih besar pada kelompok intervensi dibandingkan dengan kontrol. Oleh karena itu, dapat disimpulkan intervensi ini dapat menurunkan kadar glukosa darah dibandingkan kelompok kontrol., Hyperglycemia is a medical condition characterized by higher than normal blood glucose levels and is often associated with diabetes mellitus. Seaweed noodle is a food product made from sago flour and seaweed flour aimed at preventing hyperglycemia. The purpose of this study is to determine the effects of seaweed noodle intervention on nutrient intake, blood glucose levels, and nutritional status in people with hyperglycemia. A randomized clinical trial using a pre-mid-post with control design was carried out for 42 days in December 2023 – January 2024. The intervention had a significant effect on fiber intake (p=0.007), carbohydrate consumption (p=0.046), frequency of fruit consumption (p=0.015), and fasting blood glucose levels (p=0.027). This intervention reduced blood glucose levels in the intervention group (-23 mg/dL ± 28 mg/dL) and the control group (-1 mg/dL ± 20 mg/dL), with a greater reduction in the intervention group compared to the control. In conclusion, this intervention effectively lowered fasting blood glucose levels compared to the control group.

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.
