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

Hydroponic cultivation with a wick system is one of the techniques used to increase the production of red spinach (Amaranthus tricolor L.). One of the weaknesses of hydroponics is the appearance of nutrient deposition. To reduce nutrient deposition in the wick system, it is necessary to apply nanotechnology to break down particles in the growth media and nutrients used so that the particles become smaller and are absorbed by plants more easily. Reduces precipitation in the wick system. This research was conducted using the RAL method (completely randomized design) which consisted of 6 treatments and 4 replications namely Control (Well Water + 100% AB Mix), P1 (Nano Technology Water + 100% AB Mix), P2 (Nano Technology Water + 25% POC+75% AB Mix), P3 (nano technology water+50% POC+50% AB Mix), P4 (nano technology water+75% POC+25% AB Mix), P5 (nano technology water+100% POC). The data obtained were analyzed with variance (ANOVA) followed by the DMRT test at 5% level. The results of this study were that the use of liquid organic fertilizer with nano technology had an effect on the growth of red spinach plants, this was seen in the highest plant in P4 with a plant height of 37.20 cm with the highest average number of leaves. at P4. Control and P1 with 28 leaves, the highest average leaf surface area was 19.95 cm2 in P3, the highest average wet weight was 2.85 g in the control, the highest average dry weight was in P1. 0.67g.

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.

Abstract

NAFLD is a highly prevalent liver disease that encompasses various clinical presentations. Initially, patients are at high risk of experiencing cardiovascular events, while some may progress to advanced fibrosis or even cirrhosis, thus increasing the risk of liver decompensation and mortality. Accurate methods of diagnosing and managing NAFLD are crucial in order to minimize the impact of the disease. Moreover, the diagnosis of NAFLD is often overlooked by doctors and only receives attention when it leads to serious complications. The purpose of this literature review is to enhance the understanding of Non-alcoholic fatty liver disease, with a focus on discussing the methods of diagnosing and managing NAFLD based on published literature references from various databases. NAFLD can be diagnosed through a comprehensive approach involving clinical laboratory findings, radiological modalities, and biopsy. The management of NAFLD includes lifestyle modifications, pharmacological interventions, and liver transplantation. Despite the availability of various diagnostic methods for NAFLD in this era, biopsy remains the gold standard. The pharmacological treatment options for NAFLD are still limited, and the cornerstone of any treatment is diet, weight loss, and physical exercise. Early diagnosis and a comprehensive management approach can be beneficial for patients with NAFLD.

Abstract

Balsam plant is widely known as plants with a myriad of benefits. This plant includes plants that are easily propagated and cared for. However, plant maintenance will be important to ensure the continued growth and development of these plants. One of the environmentally friendly liquid organic fertilizers is ecoenzyme. Ecoenzyme is widely recognized as a multipurpose solution made from fermented sugar with vegetable and or fruit residue. This study aims to determine the effect of ecoenzyme solutions on the growth of Impatiens balsamina L. plants. This study followed a completely randomized design (CRD) with one factor. The data obtained were then analyzed by means of analysis of variance (ANOVA) in a one-factor completely randomized design and followed by the Duncan Multiple Range Test (DMRT) with a 95% confidence level. The results showed that on the parameters of leaf and stem length, watering with the addition of ecoenzyme had a significant effect on the growth of balsam plants starting at 30-day after culturing (DAC) and 51-DAC. Anatomical analysis of the root, stem and leaf of balsam plant treated with watering using the addition of ecoenzyme solution showed that there were significant differences with the control. The results of this study are expected to increase knowledge related to the propagation of balsam plants and the use of ecoenzyme as liquid organic fertilizer.
