Abstract

Diseases are one of the major challenges in crop production which can lead to significant economic losses. Ironically, while having multiple negative impacts, synthetic chemical pesticides are considered the main strategy in tackling plant diseases. Trichoderma asperellum is one of the potential fungal species that can inhibit numerous plant diseases. This study reconfirmed the morphological characteristics of Trichoderma isolates obtained and identified it by molecular techniques. In addition, the inhibitory activity of the isolates was tested in vitro against the mango pathogens Colletotrichum asianum and Diaporthe pseudophoenicicola. The results showed that isolate T4 was identified as Trichoderma asperellum. Isolate T4 was able to inhibit C. asianum and D. pseudophoenicicola by 28.19% and 15.64%, respectively. Therefore, this isolate can be used as a biological agent to control plant pathogens in an environmentally friendly, sustainable manner, and as an alternative to synthetic chemical pesticides.

Abstract

Stingless bees are social bees that live in colonies. Indonesia has a variety of stingless bee species that can be identified based on morphological, morphometric and nest structure characters. This study aims to describe the morphological, morphometric and nest structure characteristics of Stingless bee Tetragonula biroi from Sigi Regency. This study used the roaming method to find samples in nature, with a purposive sampling technique. Obtained morphological, morphometry and nest structure data were analyzed using the Principal Component Analysis (PCA) method with PAST4 software. The morphological characters of the worker bee Tetragonula biroi have a dominant black body, blackish brown abdomen, antennae with 11 flagellomeres, black thorax, black hair standing on the mesoscutum and mesoscutellum, brownish black mandibles, with 5 hamuli. The most dominant character in the formation of seven groups of stingless bees in this study, namely Hamuli Number (HN), Fore Wing Length (FWL), and Length of Forewing Including Tegula (WL1). The nest entrance hole of T. biroi is elliptical in shape with a width of 7.1 cm and a height of 2.8 cm and is light brown in color. The internal structure of the nest of T. biroi consists of honey cells, pollen cells and stem cells. The existence of size differences in the same specimen and from different places, can be influenced by several environmental factors and is also a form of morphological adaptation.

Abstract

Profiling the genetic character of each individual sumatran rhino is important in order to maintain individual viability and genetic variability of Sumatran rhinos. Non-invasive sampling is needed to minimize the disturbance of individual sumatran rhinos, this is due to the solitary character of sumatran rhinos and tend to be afraid to interact with humans. Until now, non-invasive sampling of sumatran rhinos in Way Kambas National Park (WKNP) has only been done through the source of the puddle. This study aims to amplify the GAPDH gene from sumatran rhino environmental DNA (eDNA) sourced from urine. Urine sampling was carried out on four of the eight sumatran rhino individuals in WKNP. DNA extraction of four sumatran rhino urine samples was carried out with reference to the DNeasy® Blood & tissue kit extraction protocol. Amplification of eDNA extraction results was carried out by polymerase chain reaction (PCR) using GAPDH primers. Visualization of extraction and amplification results from four individual sumatran rhinos at TNWK was tested qualitatively with 1% agarose gel electrophoresis. Electrophoresis results showed positive results after amplification of four individual sumatran rhino urine samples at sizes between 100-200bp. This study successfully amplified the GAPDH gene from four sumatran rhino individuals in WKNP based on qualitative tests. In further conservation efforts, it is necessary to explore eDNA extraction from other potential sources.

Abstract

Murraya koenigii (L.) Spreng is often known as Temurui or Curry as a local name in Indonesia, and has long been used in medicine and has as a potential as a multi-medicinal plant. Temurui as a producer of bioactivity has the antioxidant properties. This is due to the presence of metabolite compounds contained in the leaves of the Temurui plant. Leaves are organs that are always growing where chemical components such as chlorophyll in the leaves will also develop thereby affecting leaf metabolism in plants. This study aims to determine the contens of chlorophyll, contens of antioxidants and metabolite compounds in Temurui leaves at the level of leaf development. Different leaf extractions are also used to measure the antioxidant, chlorophyll content and metabolite compounds found in Temurui leaves. The research results obtained on young, and old Temurui leaves obtained a total of 3 groups of dominant compounds, terpenoids, organic acids and esters, and mature leaves not find ester compound. The level of leaf development affects the contents of antioxidants and chlorophyll contents. Chlorophyll content in mature leaves was 44.60ug/ml, young leaves were 41.28ug/ml and old leaves were 30.27ug/ml while antioxidant contents in young leaves were 8.949ppm, mature leaves were 8.85ppm and old leaves were 8.429ppm.

Abstract

Mussel mussels are invasive shellfish whose reproductive potential in the Lahumbuti River is unknown. This study aims to determine the seasonal variations in the reproduction of mussel shells in the Lahumbuti River, Southeast Sulawesi. This research was carried out in the Lahumbuti River Konawe, Southeast Sulawesi in 2 periods, namely: May-October 2021 and February-June 2022. The mussels were collected manually using a hand scoop. Furthermore, the shells are washed from dirt/soil attached to the shell. The length and weight of the mussels (total weight and meat weight) were measured using a caliper and a digital scale with an accuracy of 0.5 mm and 0.01 g, respectively. TKG was observed microscopically by using a gonad microscope. Fecundity was calculated by the number of type D spats in the mussel gill sieves. The results showed that male and female mussels were in developmental phases (TKG I, II and III), gonadal maturity (TKG IV) and spawning (TKG V) were found throughout the season. The actual IKG values ​​did not differ based on the time of observation, although there was a tendency for the IKG values ​​to be found to be higher in February-April. Fecundity of mussel mussels ranged from 16317-58429. The size at first maturity of male and female mussel mussels occurred at 3.9 cm and 4.7 cm, respectively.

Abstract

The production of polyploidy with a chemical mutagen such as colchicine is one strategy that can be applied to improve the genetic traits and wood properties of acacia trees. The aim of this study was to determine the effects of colchicine at various concentrations and immersion times on the percentage of surviving explants, percentage of rooted explants, and morphological traits of shoot and root A. crassicarpa in-vitro. A completely randomized design (CRD) with two factors was used in this study. The first factor was the concentration of colchicine solution with five levels (0,00%, 0,02%, 0,04%, 0,06%, and 0,08%), and the second factor was the immersion time with three levels (24, 48, and 72 hours). There were fifteen treatment combinations with each treatment repeated three times. Data were analyzed by ANOVA and Duncan’s multiple range test at 5% significance level. The results showed that the treatment combination of colchicine concentration with immersion time showed a significant effect on the percentage of surviving explants, number of leaves, number of shoots and height of A. crassicarpa explants, but did not significantly affect on the number of roots, length of the root and percentage of rooted A. crassicarpa explants.

Abstract

Rice snails are one of the pests that have the potential to cause high losses to rice plants. Rice snail mucus contains glycosaminoglycans, proteoglycans, glycoprotein enzymes, copper peptides, metal ions, collagen, elastin, glycolic acid, allantoin, antimicrobial peptides and vitamin C. Vitamin C or ascorbic acid is one of the vitamins needed by the body that functions as a help process in the body's metabolism. To determine vitamin C levels can be done using the UV-VIS spectrophotometry method with a wavelength of 260 nm. This study aims to determine vitamin C levels from rice snail mucus concentration of 100% and rice snail mucus concentration of 50%. This study is descriptive quantitative, analyzing vitamin C levels obtained from a spectrophotometer can be seen from the absorbance of rice snail mucus. Based on the results of research obtained from the analysis of vitamin C levels of rice snail mucus, the concentration of 100% is 2,372. While vitamin C levels in rice snail mucus concentration of 50% were obtained at 0.911. So it can be concluded that there are vitamin C levels in rice snail mucus with a concentration of 100% greater absorbance than 50% rice snail mucus.
