Abstract

Tamarind plant (Tamarindus indica L.) is one of the alternative plants that is widely used by the community in the medical and culinary fields. The utilization of tamarind leaves has been developed from generation to generation in traditional communities to urban areas until now. traditionally has medicinal properties. The content of tannin compounds, flavonoids, anthroquinone, saponins. Alkaloids contained in tamarind leaves can act as antibacterial. This study aims to identify the content of chemical compounds in tamarind leaves. The design of this study used a randomized block design. The research stages began with organoleptic testing of tamarind leaves, making extracts of young tamarind leaves and old tamarind leaves, then phytochemical screening tests (alkaloid test, flavonoid test, saponin test, tannin test, and steroid/triterpenoid test) and and continued with antibacterial activity test. The results showed that young tamarind leaves did not contain alkaloids and saponins, while old tamarind leaves contained flavonoids, alkaloids, tannins, and steroids/terpenoids. The antibacterial activity of young tamarind leaves was higher than that of old tamarind leaf extract. Keywords : Phytochemical Compounds, Ethanol, Tamarind, Randomized Block Design

Abstract

Household plastic waste becomes an increasingly serious environmental problem if not managed properly. This community service activity aims to improve public knowledge, skills, and awareness in managing plastic waste through training in making creative decorations based on recycling. Participants in the activity were housewives and youth in Perampuan Village, Labuapi District, West Lombok Regency. The implementation method uses an experiential learning approach through stages of socialization, environmental education, introduction to recycled product innovations, training in making decorations, and evaluation and reflection. The results of the activity showed high enthusiasm from the participants, where all participants succeeded in producing at least one type of decoration independently. As many as 90% of participants showed an increase in understanding of the impact of plastic waste and the principles of 3R management. In addition to mastering technical skills, this activity also gave rise to creative economy-based entrepreneurial ideas from some participants. This community service activity provides a positive contribution in building environmental awareness, empowering the community economically, and supporting community-based plastic waste management efforts.

Abstract

This study aims to analyze the morphometric anatomical wings of the fruit fly Bactrocera dorsalis Complex. The species used in this study consisted of 11 (eleven) species. The analysis technique of the wings of Bactrocera dorsalis Complex, i.e. the right wing of each individual was analyzed using Morphometric landmarks with 15 anatomical points. Digital images of wings are scaled in size and scale using Adobe Photoshop CS3 software. The results of anatomical point digitization are processed into MorphoJ software v. 1.06b. Digitization data of anatomical points of wing shape was collected using Generalized Procrustes Analysis (GPA).  The results of the Canonical Variate Analysis (CVA) showed that there was a grouping of each species. The grouping of Bactrocera dorsalis complex wing types is based on the similarity of the percentage of cumulative values of CVA1 and CVA2 tests. Groups B. carambolae, B. minuscula, B. occipitalis, B. papayae, B. floresiae, B. philippinennsis, Bactrocera sp. 23, Bactrocera sp. 25, and Bactrocera sp. 26 grouped because they have similarities in wing venation. The difference in wing venation is found in Bactrocera sp. 27 and B. sumbawaensis because they are far from the group B. carambolae, B. minuscula, B. occipitalis, B. papayae, B. floresiae, B. philippinennsis, Bactrocera sp. 23, Bactrocera sp. 25, and Bactrocera sp. 26.

Abstract

Indonesia is known as a rich country in herbs, which are utilized as a source of natural herbal medicine, including garlic. This research aims to achieve a comparative study of the bioactive compounds retained in several varieties of Sembalun garlic. The research was conducted at the Integrated Laboratory of Mataram State Islamic University and Laboratory of Biology, Faculty of Mathematics and Natural Sciences, University of Nahdlatul Wathan Mataram. Three varieties of Sembalun Garlic were used in this research, namely the Nunggal, Jamak and Sanggah varieties, which were extracted using 96% ethanol. The research results show bioactive compounds in flavonoids, saponins, steroids and phenolics in the three varieties of Sembalun garlic (Nunggal, Jamak, and Sanggah).

Abstract

The ethnobotanical study of food crops is very important to be carried out because it can be a means of natural resource conservation, social and economic sustainability of local communities. The diversity of food crops on the island of Lombok reflects the interaction between humans and the environment as well as the cultural values contained in the practice of using food crops in daily life. The objectives of this study are to: a) identify food crops on the island of Lombok based on land characteristics, b) find out the distribution of food crops on the island of Lombok based on land characteristics, and c) find out how food crops are used by the community on the island of Lombok.  The sample was determined using the purposive sampling technique. Data were collected through semi-structured interviews and then plant specimens were collected accompanied by key informants in the field. Data analysis was carried out in a qualitative descriptive manner after being processed in Microsoft Excel using simple statistical techniques. Based on the results of the study, about 64 species of food crops were found. Land characteristics consist of wetlands, sandy lands, and dry lands. A total of 46 species of food crops were found in rice fields with wetland/clay characteristics. A total of 30 species of food crops were found on land with sandy characteristics and as many as 18 species of food crops were found on hilly land with dry land characteristics. The use of food crops by the community is ground as much as 10%, mashed as much as 12%, cooked as much as 60% and eaten raw as much as 40%. Based on the results of this study, it can be concluded that food crops are more commonly found on land with wetland or rice field characteristics and the use of food crops is most obtained by cooking.
