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: Effect of Seaweed Noodle Intervention on Nutritional Status and Cholesterol of People with Hyperglycemia and Obese
Abstrak: Mi rumput laut merupakan pangan fungsional dengan kandungan serat yang cukup tinggi. Produk ini diharapkan dapat membantu mengontrol kadar kolesterol darah dan memberbaiki status gizi penderita hiperglikemia dan obesitas. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian mi rumput laut terhadap status gizi dan kolesterol penderita hipergikemia dan obesitas. Penelitian ini menggunakan rancangan percobaan lengkap (RAL) dengan pemberian perlakuan mi rumput laut kepada kelompok intervensi dan mi kontrol kepada kelompok kontrol selama 42 hari. Hasil penelitian ini menunjukkan terdapat pengaruh signifikan pemberian mi rumput laut terhadap asupan serat (p<0,05). Namun, penelitian ini tidak memengaruhi status gizi dan kadar kolesterol darah yang ditandai dengan nilai p-value >0,05., Seaweed noodles are a functional food with high fiber content. This product is expected to help control blood cholesterol levels and improve the nutritional status of people with hyperglycemia and obesity. This study aims to determine the effect of giving seaweed noodles on the nutritional status and cholesterol of hyperglycemia and obesity sufferers. This study used a complete experimental design (CRD) by giving seaweed noodles to the intervention group and control noodles to the control group for 42 days. The results of this study showed that there was a significant effect of giving seaweed noodles on fiber intake (p<0.05). However, this research did not affect nutritional status and blood cholesterol levels which were indicated by a p-value >0.05.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
