Abstract

Beras bambu kini mulai terkenal dikalangan masyarakat. Beras ini memliki kandungan protein tinggi dan memiliki harga yang lebih mahal dibandingkan dengan beras putih pada umumnya. Tujuan penelitian ini untuk melihat karakter morfologi pada beras bambu dan membandingkan dengan beras putih. Metode yang digunakan yaitu metode pengamatan visual menggunakan mikroskop digital 100x, pengukuran lainnya mengunakan jangka sorong dan timbangan analitik. Dari hasil pengamatan menunjukkan adanya perbedaan beras bambu dengan beras putih yang terlihat dari warna, berat, panjang, lebar, tebal maupun bentuknya. Beras bambu memiliki warna hijau, berat 0.040 gram, panjang 7 mm, lebar 3 mm, tebal 2 mm, bentuk lonjong pipih panjang dan jumlah bulir per 100 gram sebanyak 37 bulir. Sedangkan beras putih memiliki warna putih, berat 0.020 gram, panjang 7 mm, lebar 2 mm, tebal 2 mm, bentuk bagian bawah lonjong dan bagian atas setengah meruncing dan jumlah bulir per 100 gram sebanyak 63 bulir. Perbedaan warna beras bambu disebabkan karena adanya kandungan gizi dan klorofil tinggi terbuat dari sari pati bambu yang telah di perlakukan pada saat proses penggilingan. Dan dapat disimpulkan bahwa karakter morfologi yang sangat membedakan yaitu pada pengamatan warna, berat, lebar, bentuk dan jumlah bulir per 100 gram.

Abstract

Black Sapote (Diospyros digyna), also known as black sapote, is a tropical fruit that has high economic potential and health benefits. This study aims to identify secondary metabolite compounds found in Black Sapote pulp through maceration extraction methods and GC-MS (Gas Chromatography-Mass Spectrometry) analysis. Samples were extracted using 96% ethanol solvent and analyzed qualitatively and quantitatively. Phytochemical screening results showed that only terpenoid compounds were detected, while flavonoids and steroids were not found. GC-MS analysis identified five derivatives of terpenoid compounds, with cumulative levels of 21.04%, consisting of esters and sesquiterpenes. These ingredients show important bioactivity potentials, such as antimicrobial, antioxidant, and anti-inflammatory properties. These findings indicate that Black Sapote has the potential to be developed as a natural raw material in functional food products, herbal cosmetics, and pharmaceuticals. The lack of local research related to the bioactive content of this fruit opens up opportunities for further research for exploration and utilization in the development of tropical biological resource-based industries.

Abstract

The aim of this research is to determine whether there is an accumulation of heavy metals in lowland rice fields cultivated along the MKTT Trans Sumatra toll road and to find out the factors that influence the distribution of heavy metals in lowland rice fields along the MKTT toll road. The method used in the research is quantitative descriptive method. After averaging the heavy metals Lead (Pb), Cadmium (Cd) from the three sampling locations, the highest level of PB or lead metal was 0.0000618251ppm, while the highest level of Cadmium (Cd) was 0.000007234ppm, based on this it can be It can be concluded that the highest metal content is in Lead (Pb), namely 0.0000618251ppm. Based on this data, it can be concluded that plants or crops located near the roadside have the potential to be contaminated or contaminated with heavy metals due to nearby transportation activities which produce emissions, etc. and other factors. from the use of fertilizers and pesticides used by farmers.
