Abstract

Background: Tofu liquid waste tofu contains a low pH of 3 (acidic), because in the manufacturing process there is the addition of a prickly heat, it will cause pollution. One of the efforts to minimize pollution is by doing phytoremediation by combining Pistia stratiotes and Eichornia crassipes. The purpose of this study was to determine the effect of phytoremediation Pistia stratiotes and Eichornia crassipes on changes in pH and plant morphology. Methods: The method used was an experiment with four treatments and three replications by combining 0 g (control) biomass (P0), 75 g Pistia stratiotes and 25 g Eichhornia crassipes (P1), 50 g Pistia stratiotes and 50 g Eichhornia crassipes (P2), and 25 g of Pistia stratiotes and 75 g of Eichhornia crassipes (P3) which will be phytoremediated into four liters of waste with a concentration of 25%. The experimental data were processed by analysis of variance at the 5% level. Results: The results showed that the four treatments were able to increase the pH value of tofu liquid waste for P1 with an average of 6.0 while P0, P2 and P3 had an average pH of 5.7. Conclusions: The morphological structure that showed the best results was P3 with green leaves and stems.

Abstract

Background: Coal burning activities at PLTU leave large amounts of waste every year, which can become a problem of environmental pollution. Bottom ash is known to contain nutrients needed by plants. This study aims to determine the effect of adding a mixture of compost as an ameliorant to bottom ash on the pH and plant growth of Capsicum annuum. Methods: The study used a completely randomized design (CRD) with 3 replications and 4 formulations, namely B0 = coal waste (200g); B1 = 100g of bottom ash: 100g of planting medium; B2 = 50g bottom ash: 150g planting medium, and B3 = 150g bottom ash: 50 g planting medium. Parameters observed included plant height, number of leaves, root length, number of roots, total biomass and pH. Results: The results showed that treatment B0 had the highest pH and B2 had the lowest pH. Treatment B2 successively showed the highest plant height, the largest total biomass, and the highest root length, and had a significant effect on leaf number, but had no significant effect on root number. Conclusions: Based on the results of the study showed that the application of bottom ash with soil compost media had an effect on the pH and the growth of C. annuum plants, especially on plant height, number of leaves, total biomass, and root length of C. annuum plants

Abstract

Background: Biology education has a vital role in scientific development, strengthening the position of biology education for sustainable development and advancing biological science. During this time, biology materials developed rapidly. Methods: Writing the word Abstract using Cambria 9pt, in italics. The Abstract consists of 150-250 words written in one paragraph, containing the essence of the manuscript, background, research objectives, methods, results, and conclusions. Results: Biology education material that has developed since there were three changes to the curriculum in Indonesia after the issuance of Law Number 20 of 2003 concerning the National Education System does not appear to have shown any significant changes specifically in the subject matter for class X SMA. Curriculum policies and the development of textbooks in Indonesia focus more on and continue the material in the previous curriculum since the emergence of the competency-based curriculum (2004). Conclusions: The development of biology education in Indonesia from materials, textbooks, and curriculum policies does not show a significant change and development in the development of biology science for class X SMA. This study concludes that textbooks and curriculum policies have not been able to change the perspective and substance of the direction of learning biology in Indonesia. So the portrait of the capacity and insight of the Indonesian generation's knowledge about biology can be seen from the curriculum policies and the existing materials.

Abstract

Background: Microspores are small haploid spores that develop into the male gametophyte. Microsporocytes undergo meiotic division to form microspores. Microspores can be found in seedless and seed plants. The microspores in each flowering plant are different. This study aims to observe microspores on eggplant flowers. Method: Microspore observations were carried out on different flower bud sizes until the flower buds bloomed. Result: The results showed microspores in eggplant had different stages of development for each flower bud size. The stages of microspore development observed were Early uninucleate (Young microspore), Mid-uninucleate, Late uninucleate (Vacuolate microspore), early binucleate (Young bicellular pollen), mid-binucleate, and mature pollen. Conclusion: In eggplant microspore culture, anther length is a strong parameter to predict the stage of microspore development contained there in.

Abstract

Background: Cambodian trees are known to be resistant to biotic and abiotic stresses which may be influenced by the presence of rhizosphere bacteria as Plant Growth-Promoting Rhizobacteria (PGPR). This study aims to isolate and characterize Cambodian tree rhizosphere bacteria from burial soils that have the potential to produce IAA. Methods: Rhizospheric soil samples were taken from Pracimaloyo TPU, Surakarta, Central Java, at 5 points attached to the surface of the frangipani tree roots to be inoculated using the scattering cup method at 10-5 and 10-6 dilutions in NA (nutrient agar). After 48 hours, colonies were counted to obtain population data. The ability of rhizosphere bacteria to produce IAA was carried out qualitatively and quantitatively at the age of 24 and 48 hours of culture. Rhizospheric bacteria isolates potential to produce IAA were characterized macroscopically (colony morphology) and microscopically by Gram staining. Results: The population of frangipani tree rhizosphere bacteria in all blocks did not show a significant difference and was detected to have a population between 1.9 – 10.4 x 106. Qualitative test of the ability to produce IAA, it was detected that 34.88% of isolates produced very high IAA. The highest concentration of IAA was produced by isolate P37, followed by P38 and P24 at 48 hours of age, namely 113.58 ppm, 77.95 ppm, and 55.69 ppm. All potential isolates to produce IAA are cocci-shaped gram-negative bacteria. Conclusion: The population of frangipani tree rhizosphere bacteria in Pracimaloyo TPU ranged from 1.9-10.4 x 106 CFU/g and 34.88% had the ability to produce IAA. The concentration of IAA produced was higher at 48 hours of culture compared to 24 hours with the highest concentration by isolate P37 (83.098 ppm and increased to 113.588 ppm). Isolate P37 is a gram-negative cocci-shaped bacterium and irregular colonies.

Abstract

Background: Baringeng is a corn-producing village in Soppeng Regency, South Sulawesi. The main problem for corn farmers in the town is insect pests. Insect pests damage the plant, which has an impact on decreasing yields. Control of insect pests must be by the type of insect pests. This study aims to calculate the diversity of insect pests of corn in Baringeng Village and the damage they cause. Methods: Data was collected in Takku Hamlet, Baringeng Hamlet, and Tanjonge Hamlet. with a systematic plot sampling method with the help of light traps, sweep nets, and direct collection of pests. Observations included the number of individuals and types of insect pests. Data were analyzed by the Shannon-Wiener diversity index (H'), evenness index (E), dominance index (C), and similarity index. Results: There were three types of insect pests with a total of 153 individuals that attacked corn in Baringeng Village, namely grasshoppers (Oxya sp.), planthoppers (Peregrinus maidis), and armyworm (Spodoptera frugiperda). The diversity index is included in the low category (H'=0.89), the evenness index (E) is in the high sort (E=0.81), the dominance index is in the low sort (C=0.44), and the lowest similarity index shown between Dusun Baringeng and Dusun Takku (IS=50%). Conclusions: The types of insect pests found in Baringeng Village come from three different orders, namely Orthoptera, Lepidoptera, and Hemiptera. Each problem shows other attack characteristics, but all attack the leaves. So that pest control can use natural materials by spraying on leaves, polyculture, crop rotation, or taking pests directly.
