Abstract

The use of feed in fish farming is often inefficient because fish only partially consume the feed spread in ponds, so it becomes waste for the aquatic environment and, even worse, will trigger new diseases. The Department of Chemistry's of Universitas Andalas team was trying to overcome this problem by increasing the efficiency of fish feed. For the feed to work optimally and produce good quality fish weight, it is necessary to modify the nutrition of the fish feed, one of which is by adding probiotics through a fermentation process. The method used in this activity includes training, mentoring, and demonstration plots in feed fermentation and counselling regarding the right time to feed. This activity targets fish farmers in the Koto Luar area, Pauh District, Padang, with a fish culturing group, "Family Sepakat", as the partner. Feed fermentation was carried out with probiotic starters such as Bacillus sp., saccharomyces cerevisiae, L. fermentum, L. plantarum, and W. paramesenteroides. This activity improved catfish growth, and the death rate was lower than in catfish farming without feed fermentation treatment.

Abstract

A heterogeneous catalyst is one type of catalyst which is very effective for biodiesel production; thus, in this study, a novel heterogeneous bifunctional catalyst was prepared by kaolinite clay obtained from Padang of West Sumatera and impregnated with graphene oxide and potassium hydroxide (KOH) for the simultaneous esterification and transesterification reactions of palm oil into biodiesel. For comparison, two other catalysts were also prepared. The first catalyst was the same clay which was heated at 450ºC for 4 hours, and the second catalyst was the same clay which was impregnated with potassium hydroxide (KOH) only. The three catalysts were characterized using X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), and Fourier Transform Infra-Red (FTIR). XRF analysis showed that the clay sample’s main composition consisted of 54% silica, 35% alumina, and 7% hematite. The XRD analysis results showed that the most dominant crystal composition was quartz, kaolinite, and hematite. The analysis results using FTIR showed a change in intensity and shift in wave numbers indicating a cation exchange. The catalytic activity test was carried out with a ratio of oil and methanol 1:6, catalyst amount 5%, 60ºC reaction temperature, and 4 hours of reaction time.The results showed that the catalytic activity of clays impregnated with graphene oxide and potassium hydroxide was better with a yield of 58% compared to clays without impregnation and other clays that were only impregnated with KOH under the yields of 0.8% and 0.4%, respectively

Abstract

In this study, TiO2 nanoparticles were synthesized without adding extract (0% v/v) (control) and with the addition of Gunung Omeh orange peel extract with various concentration, namely 4% v/v, 10% v/v, and 20% v /v. This study aims to study the use of Gunung Omeh orange peel extract on the formation of TiO2 nanoparticles and determine its characteristics. The characteristics of the resulting nanoparticles were characterized using X-Ray Diffraction (XRD), Diffuse Reflectance Spectroscopy, Ultraviolet-Visible (DRS UV-Vis), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), Brunauer-Emmett-Teller (BET), Fourier Transform Infrared (FTIR), and Thermo Gravimetric and Differential Thermal Analyzer (TG-DTA). XRD results showed that the TiO2 phase formed was anatase. The optical property of TiO2 nanoparticles showed that the obtained TiO2 nanoparticles absorb in the UV region (200-400 nm). The results of SEM-EDX show that the resulting TiO2 nanoparticles are spherical. Meanwhile, the TOKJ20 sample has increased agglomeration so that the particle shape is rod-like. The EDX spectrum showes the presence of Ti and O peaks indicated the formation of TiO2. The results of BET measurement showed that the control TiO2 had a larger surface area of 66.11 m2/g compared to TiO2 using the addition of other orange peel extracts. From the results obtained, it was concluded that, in general, the addition of orange peel extract did not significantly affect the formation of TiO2 nanoparticles.

Abstract

SrTiO3 thin layer were synthesized through solvothermal method by using FTO (fluorine-doped tin oxide) glass as a conductive substrate. The raw materials strontium nitrate (Sr(NO3)2) and titanium tetra isopropoxide (TTIP) were dissolved in ethanol solvent. Sample purity, elemental compositions and surface morphology were characterized using x-ray diffraction (XRD), energy dispersive x-ray (EDX) and scanning electron microscopy (SEM). XRD analysis showed that the synthesized SrTiO3 thin layer at 200oC for 24 hours with the addition of CTAB and TBA had intensity peaks that mathced the SrTiO3 standard (ICSD #94573) with perovskite structure. This result was supported by the XRD pattern of the sample powder. The EDX spectrum showed that titanium and oxygen were in the sample, but the presence of strontium was not found, due to its weak intensity. Based on the SEM image, the morphology seen is distributed equally and the grain size is rather smaller in the sample with the addition of CTAB and TBA.

Abstract

Bengkulu City is an area that has a high potential threat of natural disasters. One effort that can be made is to form a Disaster Preparedness School (SSB). The Bengkulu Provincial Government has formed SSB which is a program of the United National Development Program (UNDP). However, when a school has been labeled SSB but the community in the school environment is not ready, of course, it will be a problem and interesting to study. The aim of this research is to look at the preparedness of students at disaster preparedness schools (SSB) in Bengkulu City in facing the threat of disaster. This research method is qualitative, and descriptive in nature. The population in this study were elementary schools, middle schools, and high schools located in the red zone of disaster threat in Bengkulu City. The sample in this study consisted of a sample of the school environment and a sample of respondents (students and teachers). School environment samples were taken using purposive sampling techniques. Sampling considerations are 1) elementary schools, middle schools, and high schools located less than 500 meters from the beach; 2) a topography of 25 meters above sea level; and 3) a slope of 0% -15% from sea level. The samples in this study were SD Negeri 1, SMP Negeri 15, and SMA Negeri 6 Bengkulu City. The sample of respondents were students. The sampling of student and teacher respondents in this study used the Proportionate Stratified Random Sampling technique by taking 10% of the number of students per class in each disaster-prepared school. The sample of student respondents was 187 students and the sample of teacher respondents was 117 people. This research will be carried out for one year—data collection techniques using questionnaires, interviews, and documentation studies. The research results show that the preparedness of students at the disaster preparedness school SDN 1 Kota Bengkulu falls into the ready category with a score of 53.9 or 50.0075. The readiness of students at the disaster preparedness school SMPN 15 Bengkulu City falls into the ready category with a score of 53.57 or 50.0075. The preparedness of students at the SMAN 6 Bengkulu City disaster preparedness school is included in the ready category which is at 71.25 or 75.00.

Abstract

This research investigates public opinion on the divorce of social media celebrity Ria Ricis, utilizing Sara Mills' Critical Discourse Analysis (CDA) framework to explore the discourse surrounding this event on social media. Ria Ricis, widely recognized for her YouTube presence, and her marriage to Teuku Ryan attracted significant attention, with their subsequent divorce sparking extensive reactions on social media, particularly on the popular Instagram account @lambe_turah. The study analyzes the subject-object positions in the discourse, revealing the power dynamics and ideological content embedded within the narrative. Drawing on previous studies that employed Mills’ CDA framework, this research aims to uncover how public figures' personal lives are constructed and interpreted in social media discourse, and how these representations reflect broader societal attitudes towards celebrity relationships and authenticity on social media platforms.

Abstract

Implementation of the Independent Curriculum set by the government raises a number of challenges in the field, especially those related to teacher and school readiness. This curriculum demands a comprehensive understanding from educators and school officials, especially at the elementary school level. This research uses a qualitative descriptive approach, with data collection through observation, interviews and document analysis. The data analysis process includes stages of reduction, presentation and drawing conclusions. The research results show that the readiness of teachers in Padangsidimpuan City public elementary schools in implementing the Independent Curriculum is at a fairly good level. This is reflected in the teacher's ability to understand the main components of the curriculum, including lesson planning, implementation of the teaching and learning process, and learning assessment. Teachers also demonstrate adequate understanding of learning tools, such as legal foundations, learning objectives, media, learning models, and supporting facilities and infrastructure. This readiness is supported by teachers' active participation in various professional development programs, such as training through the Merdeka Mengajar Platform (PMM), seminars, webinars, workshops and In House Training (IHT). Apart from that, teachers are able to develop open learning modules, implement differentiated learning in class, and carry out evaluations according to the Independent Curriculum guidelines.

Abstract

The intention and purpose of creating adaptations are often discussed in the film adaptation and comparative study. By using adaptation theory from Desmond and Hawkes (2006) and the instinctive theory of life and death from Sigmund Freud, this research aims to analyse the different ideas between the novel “Mickey7” and the film “Mickey17”. The analysis includes finding the intrinsic elements of both data sources and by using Freud’s life and death instinct theory, psychoanalysing the two main characters. The result showed that “Mickey17” is an intermediate adaptation. The main characters in the novel, Mickey7 and Mickey8, represent the life instinct as they both want to live and show that they want to live by solving their problem together to not being eliminated. However, the main characters in the film, Mickey17 and Mickey18, represent life and death instincts, respectively. While Mickey17 has affection and sexual desire, Mickey18 is a Mickey who is more violent and antagonistic towards Mickey17 and the other characters around them.
