Abstract

Enggano Island has a unique and interesting endemic species to study. Data collection on the Enggano's herpetofauna was last carried out in 2015, and there was a data gap for six years. Therefore, it is necessary to research herpetofauna diversity on the island. The study used Visual Encountered Survei (VES) combined with patch and time search sampling at diurnal and nocturnal active times. We also compiled the  data on herpetofauna species in books, journal publications, database specimens from museums worldwide, and recorded observations of individual species. We surveyed four research sites on Enggano Island (Kaana, Malakoni-Apoho, Meok, and Banjarsari). We preserved some specimens for each unprotected species in ethanol 70% and identified with Sumatran herpetofauna field guide.  From the research, we concluded that there are 15 species of herpetofauna found in this study (4 species of amphibians and 11 species of reptiles). We found 2 endemic species of the island (Draco modiglianii and Cnemaspis modiglianii). Previous research has not reported two new record species of amphibians, i.e., Fejervarya limnocharis and Duttaphrynus melanostictus. This research has not yet represented herpetofauna's true diversity on Enggano Island. The number of these species can still increase along with expanding the research study area, especially in conservation areas managed by BKSDA. Continuous exploration and monitoring need to be carried out to ensure future conservation management

Abstract

This research aims to identify the diversity of plants that make up peatland vegetation in the Mount Bongkok Reserved Forest after forest fires. This research is a quantitative qualitative descriptive research. The method used is the plot method. Area of observations were determined using purposive sampling with the assumption that the existing vegetation could represent the entire community. The sampling size/intensity (IS) used was 5% of the total area of 100 Ha, so the total sampling area was 5 hectares. The sampling location was divided into 50 observation plots with a size of 25x40m each plot. The results showed that Ubah (Syzygium sp.) and Pulai (Alstonia pneumatophore) plants were found at all sampling points. Geronggang plants (Cratoxylon arborescens) and Jelutung plants (Dyera lowii) were found at more than 50% of sampling points. These four plants are plants that are suitable for habitats in peatlands. This shows that this plant is suitable for growing in the peatland habitat and can be used for peatland conservation

Abstract

Currently, there has been a lot of environmental damage due to human activities. Sand mining is one of the community activities in Indragiri that has caused various damages in the area around the river such as polluted river water, damaged roads due to frequent sand-carrying trucks, landslides due to erosion, and noise due to sand suction machine activities. If no efforts are made to manage the environment sustainably, this situation will get worse in the future. This condition encourages the need for efforts to minimise various environmental damages, one of which is through education. The purpose of this study is to analyse students' attitudes and behaviour towards the river environment so that the results of this analysis can be used as a basis for developing environmental education programs so that the program is right on target and according to needs. This survey research involved 151 students who were taken using purposive sampling. The instrument used was a questionnaire with 35 questions. Data analysis was done with descriptive quantitative. The results showed that; (1) students already have good positive attitudes towards the river; (2) most students already have good behaviour towards the river; (3) there is a relationship between students' attitudes and behaviour towards the river; (4) students already have good attitudes and behaviour towards sand mining activities around the river. However, efforts still need to be made to equip students with the knowledge, skills, values and attitudes needed to contribute more to the preservation of the surrounding river environment

Abstract

Seeds as planting material play an important role in agricultural development. The high demand for oil palm sprouts causes the long germination time to become an obstacle for consumers and seed producers. The aim of this research is to examine varieties on germination capacity of oil palm seeds. Research was conducted at the PPKS Seed Processing Unit on nine PPKS varieties (Simalungun, PPKS 540, Yangambi, PPKS 239, PPKS 718, Dumpy, Avros, Langkat, and PPKS 540 NG). The parameter observed was the germination power (DB) of the seeds. The treatment given in the germination process for all varieties is carried out to ensure that the environment is favorable for germination (according to the SOP). Observation results showed that PPKS 540 variety had the highest DB (84.9%), followed by Simalungun (81.46%), PPKS 540 NG (75.46%), Langkat (75.43%), Dumpy (73.41 %), PPKS 718 (72.29), Yangambi (68.81%), PPKS 239 (65.74%), and Avros (56.92%). This is thought to be due to the influence of internal factors, related to the conditions of the germinated seeds, both genetics and hormones, as well as external conditions which include optimal water, temperature and oxygen treatment during germination. The results show that the water content (KA) of the seeds in the soaking period (I) was 16-20%, and soaking (II) was 19-22%, all processed seeds were still at a safe level of water content for the process of breaking dormancy of oil palm seeds. The characteristics of parent tree of the seed variety are the cause of differences in seed germination

Abstract

The ability to think critically at the levels of analysis (C4), evaluation (C5), and concentration (C6) is known as Higher Order Thinking Skills (HOTS). The ability to discern high school students is really low, according to the researchers. The ability to monitor students at a higher level is weakened because students need a learning style or model that suits their needs in order to achieve their learning goals. With the ability to enhance students' HOTS, Project-Based Learning (PjBL) is a teaching methodology that may be applied to the biological sciences. Because of this, the research in this study used quantitative methods, namely the normality, Levene, and hypothesis tests that used t-tests (independent samples). They were derived from the results of the hypothesis test. The results of this study show that the PjBL learning model significantly affects high-level students' understanding of biotechnology material, with a p-value of 0.000 and a p-value of less than 0.05 (refer to equation 2)

Abstract

Seed-borne fungi are fungi that are associated with seeds and can be a source of plant disease in the field. Therefore, this study aims to utilize DNA barcoding to identify seed-borne fungi isolates from Tanjung Morawa B village. This investigation took place at Tangerang's genetic science laboratory in Tangerang was the site of this investigation. Sequence and phylogenic tree building, PCR amplification with MyTaq HS Red Mix, 2X (Bioline, BIO-25048), and genomic DNA extraction with the Quick-DNA Magbead Plus Kit (Zymo Research, D4082) were the research methods used. The electrophoresis results showed that the DNA made from PCR using Primers ITS-1 and ITS-4 was of high quality. This was clear from the electrophorograms for both the TMIE isolate sample and the control. Using ITS-1 and ITS-4 for DNA amplification produced favorable results, with virtually no smears detected. The Basic Local Alignment and Search Tool (BLAST) program, which is connected to the Genebank database, was employed to analyze the sequence results in the form of a base sequence with a length of 581 base pairs. Based on the genetic similarity results of the isolate's DNA with Genebank, we determined that the TMIE isolate was 100% similar to Curvularia eragrostidis.

Abstract

Mining activities affect the balance of the soil surface ecosystem, decreasing soil productivity which causes the chemical, biological, and physical properties of the soil to be disturbed, as well as environmental quality. The purpose of this study was to determine the effect and the best composition of a mixture of compost and former gold mine soil in the growth of suren seedlings. This study consisted of 4 (four) treatments and 5 (five) replications resulting in 20 experimental units. The treatment of compost fertilizer in this study can be seen as follows: D1 = no compost/control, D2 = 25% compost + 75% ex-gold mine soil, D3 = 50% compost + 50% ex-gold mine soil, D4 = 75% compost + 25% ex-gold mine soil. The observation parameters are the percentage of life, height increase, plant dry weight and seedling quality index (IMB). The results showed that the application of goat manure compost had a significant effect on the growth of suren seedlings. Treatment composition D4 (75% compost fertilizer + 25% gold mine waste soil) showed the best growth with 100% survival rate, 21, 27 cm height increase, 10.57 g plant dry weight and 0.99 IMB

Abstract

Sparkling-soft drinks are calorie-carbonated drinks that contain a mixture of water, flavorings, and sweeteners. Sparkling drinks contain a lot of artificial sugars which can burden the liver's work to filter toxins. Consuming too many soft drinks can lead to fat buildup that is harmful to the liver. Pineapple (Ananas comosus L.) is a plant rich in calcium, phosphorus, sodium and bromelin enzymes. Pineapple (Ananas comosus L.) also contains vitamin C which functions to stimulate the production of liver enzymes and absorb toxins in the blood circulation that are excreted through the urine. In conditions of impaired liver function, it can be indicated by changes in the levels of Serum Glutamic Oxaloacetic Transminase (SGOT) and Serum Glutamic Pyruvic Transminase (SGPT). The research procedures include plant determination, making pineapple fruit extract, phytochemical screening tests, animal preparation, blood collection and surgery on animals, measuring SGPT and SBOT levels, and data analysis. The purpose of this study was to determine the effect of administration of pineapple fruit extract (Ananas comosus L.) on morphology, SGPT and SGOT levels in the liver of male white rats induced by soft drinks. The study used a complete randomized design method (RAL) with 25 male white rats from 5 groups and 5 replicates, conducted for 30 days, and 7 days of acclimatization. The results of administration of pineapple fruit extract had no significant effect on liver morphology and the dose of 400 mg/kg BB was a good enough dose in reducing SGPT and SGOT levels
