Abstract

Desa Sukaramai Dua, Aceh Tamiang, merupakan salah satu wilayah dengan potensi besar dalam produksi kelapa, namun limbah kelapa seperti sabut seringkali tidak dimanfaatkan secara optimal dan hanya menjadi sampah yang kurang bernilai. Pengabdian kepada masyarakat bertujuan untuk memberdayakan petani lokal melalui optimalisasi pemanfaatan limbah kelapa menjadi produk bernilai tinggi, yaitu cocopeat dan cocofiber, dalam rangka mendukung pengembangan ekonomi lingkaran. Program ini melibatkan beberapa tahapan kegiatan, mulai dari penyuluhan dan pelatihan teknis bagi petani mengenai proses produksi cocopeat dan cocofiber, hingga pendampingan dalam pemasaran produk hasil olahan. Metode pelaksanaan yang diterapkan meliputi pendekatan partisipatif dengan melibatkan masyarakat setempat secara aktif, serta penggunaan teknologi sederhana yang mudah diterapkan oleh petani. Hasil dari kegiatan ini menunjukkan adanya peningkatan pemahaman dan keterampilan petani dalam mengolah limbah kelapa menjadi produk yang bernilai ekonomi tinggi. Selain itu, pengembangan pasar untuk cocopeat dan cocofiber juga telah berhasil dilakukan, yang berkontribusi pada peningkatan pendapatan petani dan berdampak juga pada pengurangan limbah lingkungan. Kesimpulannya, kegiatan ini tidak hanya meningkatkan kesejahteraan ekonomi petani di Desa Sukaramai Dua, tetapi juga mendukung keberlanjutan lingkungan melalui penerapan konsep ekonomi lingkaran.

Abstract

People use the lacum plant (Cayratia trifolia L.), an herbaceous plant from the Vitaceae family that grows wild, as a traditional medicine. Lacum leaves have special things inside them called secondary metabolites like flavonoids, alkaloids, phenols, steroids, terpenoids, and tannins. Toxicity tests must be carried out because flavonoids, alkaloids and steroids have harmful effects on test animals at certain concentrations. A substance or natural ingredient that will be used as a medicine is tested to determine its level of toxicity. The purpose of this study was to determine the total levels of toxic compounds and the level of toxicity in the ethanol extract of lacum leaves (Cayratia trifolia L.) Brine Shrimp Lethality Test (BSLT). This research uses Artemia salina leach larvae as test subjects. This research also used an experimental approach arranged in a completely randomized design (CRD) consisting of 7 treatments and 4 replications. The percentage of larval death was used in probit analysis to identify the toxic effects of the extract and calculate the LC50 value. Based on the research results, it shows that there are total levels of toxic compounds in the ethanol extract of lacum leaves (Cayratia trifolia L.), namely flavonoids, alkaloids and steroids with an LC50 value of 105.08 ppm which places it in the moderately toxic category and is thought to have anticancer properties.

Abstract

Stomata, which are specialized cells on the surface of leaves, undergo modification to form structures containing two guard cells. These cells play a crucial role in facilitating the exchange of water vapor and gases between the plant's internal environment and the surrounding atmosphere. Typically located on plant parts exposed to air, such as leaves, stems, and rhizomes, stomata distribution varies among different species. While some plants exhibit stomata on both upper and lower leaf surfaces, others, like water lilies, exclusively feature stomata on the upper side.The objective of the current investigation was to analyze the stomatal anatomy of various plant species within the Euphorbiaceae family. Employing a qualitative descriptive approach, the study aimed to characterize and interpret the stomatal types present on the leaves of Euphorbiaceae plants in the Langsa City region. The findings revealed the presence of five Euphorbiaceae species in Langsa City, including Euphorbia mili (jade fern), Jatropha curcas (Jatropha curcas), Codiaeum variegatum 'Norma' (norma puring), Codiaeum variegatum Bi (jet puring), and Codiaeum finger (finger puring), all of which exhibited parasitic stomatal types.

Abstract

Starch is a type of polysaccharide formed from the polymerization of glucose. Starch is also known as starch which is a widespread reserve polysaccharide in plants. Starch is also defined as a complex carbohydrate which is very important as a food source. The purpose of this research is to determine the shape and type of starch in the tuber family. This research was conducted using descriptive methods. The purpose of this study is to describe and describe the characteristics of the forms and types of starch.Based on the results of observations, it can be concluded that the starch in taro, cassava, porang and jicama tubers has a concentric type and has regular and irregular round shapes, while potato tubers have an eccentric type and are oval or oblong in shape.Potato tubers have the highest starch of the five tubers because potatoes have a dense starch structure and contain a lot of starch or starch.

Abstract

Chlorophyll is the primary pigment in plants. Most chlorophyll is found in leaves, and its content varies among different leaves. Chlorophyll functions as an antioxidant for the body. Plants rich in chlorophyll include spinach and lettuce. Spinach and lettuce are popular vegetables among the public due to their high nutritional value. This study aims to determine the differences in chlorophyll content between these two types of vegetables. The research was conducted in the Basic Laboratory of Universitas Samudra using a spectrophotometer to identify the chlorophyll content in lettuce and spinach, determined through calculation methods. The results showed a significant difference in chlorophyll content between spinach and lettuce, particularly between green and red varieties. Green spinach had the highest chlorophyll content, whereas red lettuce had the lowest. This difference is due to pigment variations, where chlorophyll is more dominant in green varieties, while anthocyanin is more dominant in red varieties. Chlorophyll extracts from these vegetables have great potential as a natural antioxidant source that supports overall health, making them an important part of a daily diet.
