Abstract

Bryophytes is one of the various plant groups that have an important role in biodiversity. Bryophytes have an essential role in environmental ecology, including mosses contributing to the nutrient and water cycle and the carbon exchange cycle. This research aims to determine the effect of waterfall distance on bryophyte diversity in the waterfall area. This research uses an exploratory descriptive method with data collection locations at Coban Rondo Waterfall, Pujon District, Malang Regency. The research was carried out by collecting data directly in the field by observing and exploring according to the conditions at the research location. The objects in this research are classes bryophytes that grow around the waterfall area by creating three plots measuring 5m x 5m with the installation at the wet zone which is located in the waterfall area <25 m, the humid zone which is 25-50 meters from the waterfall, and the dry zone which is more than >50 meters from the waterfall. Each bryophyte found in a single plot in three zones will be analyzed by considering the factors of temperature, humidity, light intensity, and soil pH. The results of the study showed that there was an influence of waterfall distance on bryophyte diversity. The closer the location where bryophytes grow to a waterfall, the more diverse the number of species.

Abstract

Sumberawan Temple is a tourist area that is inextricably linked to diversity of plants. One of them is angiosperm plants. Angiosperms occupy about 90% of all plant species and have 250,000 species. The objective  of this study is to determine the biodiversity of angiosperm plants in  Sumberawan Temple area which is located in Singosari, Malang Regency. The research method used was vegetation analysis using a single plot measuring 20 x 20 m2. The shape of the plot used wass square with an area of ​​400 m2. There were 12 types of angiosperm plant species in 9 different families. To determine the species richness index using the Margalef index, the diversity index using the Shannon Weinner index and the evenness index using the Evenees index. The findings indicated that species richness was in the low category, diversity and evenness were in the high category. It is due to the fewer  species in the area but the greater variety of species in  Sumberawan Temple area. The diversity of species indicates the number of species that coexist.

Abstract

Used cooking oil is waste oil that comes from a type of cooking oil that has been used repeatedly. If not managed properly, it can become a source of environmental pollution. Managing used cooking oil still needs to be in a good category. Preliminary studies from this research found that as many as 60% of people in the Cengkareng Village area, West Jakarta, need to manage used cooking oil properly. This research aims to determine factors related to knowledge, attitudes, income and environment in managing used cooking oil. The sample used was 141 homemakers using purposive sampling. The data collection methods used were interviews and observation. This research uses independent variables (Knowledge, Attitudes, Income Level, and Environment) and dependent variables (Used cooking oil management behaviour). The analysis used is descriptive analysis with the chi-square test. Based on the research results, it was found that the highest proportion of used cooking oil management behaviour was poor (51.1%), good knowledge (54.6%), negative attitude (60.3%), sufficient income level (81.6%), and bad environment (93.6%). %). There is a relationship between knowledge (p-value = 0.001) and community behaviour in managing used cooking oil and a relationship between attitude (p-value = 0.001) and behaviour in the community driving used cooking oil. There is a need for interaction and cooperation between societal stakeholders to improve public awareness of cooking oil management to create a zero-waste environment.

Abstract

Diabetes is a health problem that affects more than half a billion people in the world. Several plants are known to have anti-diabetic activity, one of which is Dutch jasmine (Combretum indicum). This research was conducted to determine the effect of Combretum indicum leaf extract on blood sugar levels and histology of islets of Langerhans in mice. A total of 36 male mice aged 6-8 weeks were divided into 6 treatment groups, namely normal control (KN) without treatment; negative control (K) with alloxan treatment; positive control (K+) with alloxan and glibenclamide treatment; P1 treated with alloxan and Combretum indicum leaf extract at a dose of 100 mg/kgBW; P2 with treatment with alloxan and Combretum indicum leaf extract at a dose of 200 mg/kgBW; P3 with alloxan treatment and Combretum indicum leaf extract at a dose of 200 mg/kgBW. Mice that have been induced by alloxan will be treated with leaf extract and glibenclamide for 20 days. Blood sugar levels 3 days after alloxan induction were checked and checked again on the 10th and 20th days of treatment by taking blood through the blood vessels in the mice's tails and then measuring them using a glucometer. The pancreas was dissected on the 20th day and pancreatic histology preparations were made for histological analysis. The results of this study indicate that Combretum indicum leaf extract has antihyperglycemic effects by protecting islets of Langerhans cells from alloxan-induced oxidative stress.

Abstract

Mangosteen (Garcinia mangostana L.) is a plant that contains many benefits and has the potential to be a medicinal plant in treating various diseases. Mangosteen leaves contain flavonoids, saponins, tannins, alkaloids and terpenoids which are known to have antibacterial and antibiofilm properties. This anti-biofilm agent is an alternative treatment for diabetic wound infections where cases of antibiotic resistance have increased. One of the causes of resistance is the biofilm formed by infectious bacteria. This research is a type of laboratory experimental research which aims to determine the anti-biofilm activity of mangosteen leaf extract against biofilms formed by a collection of bacterial isolates from diabetic wounds. The antibiofilm activity test carried out consisted of a cell attachment prevention test, a biofilm formation inhibition test, and a biofilm destruction test using the crystal violet staining method using the tube method and measuring optical density values ​​on a UV-Vis spectrophotometer. The concentrations of mangosteen leaf extract used are 60%, 80% and 100% as well as control – and control +. The results of the antibiofilm test showed that mangosteen leaf extract had the best activity in inhibiting biofilm formation, preventing cell attachment, and destroying biofilm, respectively. The three most optimal activities were found at a concentration of 100%, with an inhibition percentage of 50.51%, prevention of 32.56%, and destruction of 5.63%.

Abstract

Food is a basic human need, necessary to meet daily needs. Human health is greatly influenced by what they consume. Food products added dangerous ingredients can cause serious health effects for humans. The aim of this research was to detect substances of formaldehyde and borax in snacks in the month of Ramadhan (takjil) at Bekasi City. This was descriptive observational research design by direct examination for formalin and borax from the food samples. The population in this study were all traders who sold Takjil on the roadsides in Bekasi City. Sample selected used an incidental sampling technique by taking 8 food samples which. Based on references, they were proven to contain dangerous chemicals. Based on the research results, 2 food samples were found positive containing dangerous food additives, namely 1 sample of lontong (12.5%) was positive for containing borax and 1 sample of martabak tofu (12.5%) was positive for containing Formalin. Seasonal traders who Sell ​​Takjil food during the month of Ramadan may not necessarily be safe. Therefore, it is recommended that health workers from Puskesmas must frequently inspect the food products and socialize the importance of using safe food additives.

Abstract

Biodiversity of flora in Indonesia greatly supports the development of textile products, ecoprint is one of the textile products that involves the utilization of this diversity. Various types of plants found in the surrounding environment can be used as dyes for making ecoprints. Ecoprint is a color transfer technique on fabric which in the manufacturing process requires a mordant to bind plant colors to the fabric. This study aims to determine the effect of variations in fabric type, length of time, type of mordant, and type of natural dye on ecoprint color expression. This experiment used the steaming technique in ecoprint to transfer motifs and colors to fabric. In this study, three types of fabric were used, namely: toyobo cotton, mori, and blanco. Variants of steaming time were tested at intervals of 60 minutes, 90 minutes and 120 minutes. Variations in the types of mordant used are vinegar and alum. Meanwhile, the types of natural dyes used are jolawe, soga, and secang. The results of the research show that there are differences in color expression produced by vinegar and alum mordant substances. Alum mordant produces intense color expression and clear form. Leaf motifs can be printed well on toyobo cotton fabric. Variations in steaming time in this study did not produce significant differences in color expression. Meanwhile, each natural dye produces a different color expression.
