Abstract

This study aims to determine the effect of the application of manure and bokashi fertilizer and their interaction on the growth of Red Spinach (A. Tricolor L.). This research was conducted in Atapage, Wajo Regency. The research design used was a completely randomized design (CRD) with 4 replications and consisted of 4 treatments, namely manure; bokashi fertilizer; manure + bokashi fertilizer; and without treatment. The research data were analyzed using variance and for the different tests, the Least Significant Difference Test was used at the 5% level. The results of the study statistically showed that the treatment given was significantly different from the observation parameters of plant height and number of leaves, the highest average was found in the treatment with bokashi fertilizer and the lowest was in the treatment without manure + bokashi fertilizer, while the root crown ratio parameter showed no significant difference.

Abstract

This study was conducted to determine the role of thermal treatment on the crystallinity and pore characteristics of porous ceramic, which was prepared from natural clay (NC) and chitosan (CS) biopolymer using the gel casting method. CS was used as an environmentally friendly pore-forming agent. The applied temperature treatment was based on thermal analysis (TGA/DTA) results and followed a sintering temperature of 900 to 1100 °C. The results showed that at sintering temperatures from 900 to 1000 °C, the crystallinities of the ceramic decrease (from 76.06 to 74.06%) and the crystallite size decreases (from 35.71 to 34.47 nm) while the lattice strain increases (calculated from the Full Width at Half Maximum (β) of the diffraction peak). The highest porosity of ceramic occurred at a sintering temperature of 1000 °C of 37.82 ± 0.19, but the formation of heterogeneous microstructure was observed. The resulting pore size for all temperature treatments was almost mesoporous (19.1 Å). Based on the results obtained, it is emphasized that the sintering temperature can be used to adjust the porosity and microstructure of porous ceramics.

Abstract

This study aims to determine the effectiveness of Jatropha plant in accumulating metal contaminants in the form of lead (Pb) in coal solvent. The method used is descriptive quantitative analysis method. The results showed that the metal content of lead (Pb) in the soil before and after treatment changed from 25.8904 mg/kg to 14.3991 mg/kg. In conclusion, Jatropha curcas (Jatropha curcas) is able to accumulate the presence of metal contaminants in the form of lead (Pb) because the metal concentration in the soil decreases after the acclimatization period, so this plant species is very suitable to be used as a phytoremediation effort to reduce contaminants in heavy metal polluted soil.

Abstract

This study aims to determine the variable emergence of side effects of pressure on students globally due to distance traveled during the Coronavirus pandemic. The method used is literature (meta-analysis) by reviewing articles that discuss indications of stress (stress) in college students globally. The results showed that the emergence of symptoms of pressure on students was caused by distance and piling up of coursework, learning environment, noise, limited understanding of the material obtained, limited knowledge, piled up homework, not having the option to meet friends and family including schoolmates, forced internet networks, inefficient web standards, no proper class plans, unstable internet networks, relatively expensive data costs and fatigue experienced during distance learning. As a result, students experience stress during the COVID-19 pandemic. In conclusion, students globally experience stress due to several factors arising from distance learning during the COVID-19 pandemic. Keywords: COVID-19, Symptoms of stress, Distance learning

Abstract

This study aims to develop a QR Code-based module in its use in the field practicum of invertebrate species in the Invertebrate Zoology course in the form of the Invertebrate Zoology module. This type of research is development research using the ADDIE model. The research procedure consists of 5 stages, namely analysis, design, development, implementation, and evaluation. In this study, an assessment of the use of modules as learning media was used, the instruments used in the study were material validation questionnaires, media validation, practicality questionnaires, and student response questionnaires. The data collected were analyzed quantitatively and qualitatively. The results showed that the QR Code-based module on invertebrate species material in its use in the field practicum of the Invertebrate Zoology course was feasible to use based on the assessment of material I experts as much as 88% and material II experts as much as 80% and media experts 88.5% with a very valid category. , and 80% practicality data and 85% student response questionnaire. The development of learning media based on QR Code for Invertebrate species material in its use in the field practicum for the Invertebrate Zoology course is feasible to be used as a support for learning in the Invertebrate Zoology course

Abstract

Fitoremediasi merupakan salah satu metode penanganan lahan tercemar akibat pertambangan. Penelitian ini bertujuan untuk mengkaji pengaruh penanaman tanaman vetiver (Vetiveria zizanioides) terhadap fitoremediasi limbah pertambangan yang tercemar merkuri (Hg) di Kabupaten Mandailing Natal untuk mengurangi dampak pencemaran lingkungan akibat aktivitas pertambangan. Penelitian ini dilaksanakan selama tiga bulan di Rumah Kaca FMIPA Universitas Negeri Medan dan Laboratorium Balai Riset dan Standardisasi Kota Medan. Jenis penelitian ini adalah penelitian eksperimental dengan Rancangan Acak Lengkap. Jumlah kombinasi perlakuan terdiri atas 4 variasi paparan limbah dengan 2 kali pengulangan pengujian kandungan merkuri pada tanaman. Dari hasil penelitian diperoleh tanaman vetiver mampu menyerap logam merkuri pada media tanam yang dikontaminasi dengan limbah asli pertambangan paling tinggi sebesar 7,1045 mg/Kg dan sebesar 15,68 mg/Kg pada kontaminasi limbah sintetik selama 12 hari pemaparan. Dengan bertambahnya waktu fitoremediasi, tanaman akar wangi (Vetiveria zizanioides) mampu mengakumulasi lebih banyak logam berat merkuri (Hg) yang terdapat di dalam tanah.

Abstract

Nanotechnology explores nanoscale materials that can be used in a wide range of industries such as biotechnology, cosmetics, drug delivery, nanomedicine, and biosensors. Nanoparticles in diverse shapes and sizes can be prepared through physical, chemical, and biological methods. The employment of reducing agents, which will change their form, size range, level of stability, and interaction, is a crucial part thus employing a biological approach is necessary. Chemically generated metal oxide nanoparticles raise considerable issues owing to the usage of hazardous and poisonous chemicals, as well as the potential for conservational impairment. In contrast, the production of silver nanoparticles using the principal method of green synthesis has found a special place in research that is considered more environmentally approachable requiring the use to produce non-toxic nanomaterials. Plants and polymer materials have received a lot of interest in the preparation of nanoparticles since they are renewable and affordable. In this review, we present a comprehensive overview of more ecologically friendly synthesis techniques that use plant extracts to make silver nanoparticles and their application as antibacterial agents, as well as toxicity features based on the shape, size range, and phytochemical mechanism of plants.

Mappacci is one of a series of traditional wedding rituals of the Bugis tribe. This research aims to classify and identify various types of plants and the meaning of their use in the traditional rituals of the Bugis mappaci tribe. This research method is descriptive qualitative. Data collection through observation, interviews and documentation. The results of the research found 7 types of plants in the Mappacci traditional ritual. The plant species used are Pacar (Lawsonia inermis L), Jackfruit (Artocarpus heterophyllus Lam), Banana (Musa paradisiaca L), Rice (Oryza sativa L), Coconut (Cocos nucifera L), Palm (Arenga pinnata Merr) and Cotton (Ceiba pentandra) which includes 6 families, namely Lythraceae, Moraceae, Musaceae, Poaceae, Arecaceae, Bombacaceae. The plant parts used are leaves (75%), fruit (50%), seeds (25%), sap (25%). The plants used in the Mappacci traditional rituals of the Bugis tribe have a philosophical meaning of goodness. Community knowledge in the use of these plants is a tradition passed down from generation to generation from their ancestors
