Abstract

Catfish (Clarias sp.) aquaculture is a promising sector with high economic potential in Indonesia. However, challenges related to production efficiency and environmental sustainability often hinder its growth. This study investigates the design and implementation of a biofloc system aimed at enhancing catfish (Clarias sp.) aquaculture in Gampong Mata Ie, Montasik, Aceh Besar, Indonesia. The biofloc technology presents a promising solution to the challenges of production efficiency and environmental sustainability in catfish farming by optimizing water quality and maximizing feed utilization through efficient nitrogen cycling. Employing both qualitative and quantitative methodologies, the research involved a comprehensive site survey to assess initial conditions and specific requirements of local catfish farming. The biofloc system design encompassed material selection, pond configuration, and technical parameters such as aeration, water circulation, and organic carbon supplementation. Implementation results demonstrated significant improvements in water quality, with ammonia and nitrite levels maintained within safe limits. Additionally, catfish growth was optimized, evidenced by lower feed conversion ratios, indicating enhanced feed efficiency. From a zoological perspective, the biofloc system provides an environment that closely mimics natural conditions, supporting the welfare of catfish. Ecologically, this technology mitigates negative environmental impacts by minimizing waste and water usage. The application of biofloc technology in Gampong Mata Ie underscores its potential to not only enhance production outcomes but also contribute to local economic and environmental sustainability. This research concludes that the biofloc system design and implementation represent an effective and sustainable strategy for catfish farming, offering significant benefits from both zoological and ecological perspectives. It is anticipated that these findings will serve as a reference for catfish farming developers in similar regions and promote the broader adoption of biofloc technology in the Indonesian aquaculture industry.

Abstract

Social changes in a society can help provide information related to that society. Qanun is a statutory regulation or a kind of regional regulation that regulates the life of the Acehnese people. This study aims to determine the social changes that occurred in Ie Jeureungeh Village. In addition, to find out the understanding of the residents of Ie Jeureungeh Village towards the wildlife Qanun. The benefits of this research are to provide information, add insight and knowledge. This research was conducted using descriptive qualitative method and focal animal sampling. The research subjects were 24 people with the technique of taking using purposive sampling technique. The study to determine the social changes that occurred in Ie Jeureungeh Village used 3 factors, namely, causative factors, pushers and inhibitors. The results showed that there were social changes that occurred in Ie Jeureungeh Village, and the people of Ie Jeureungeh Village tended to know about the wildlife Qanun.

Abstract

This study explores the underutilized potential of bôh gadông flour, derived from Dioscorea alata tubers, as an ingredient in roll cake production. Despite its abundance in certain regions, the use of bôh gadông in modern culinary applications remains limited. This research aims to address this gap by (1) standardizing roll cake recipes incorporating bôh gadông flour, (2) evaluating the organoleptic attributes (color, aroma, texture, and taste) of the cakes, (3) assessing consumer acceptance of bôh gadông flour roll cakes, and (4) analyzing the storage quality of the cakes over time. Conducted through experimental research at the Catering Laboratory of the Family Welfare Education Program, Universitas Syiah Kuala, the study employs quantitative methods. Observational data are analyzed using mean calculations, while consumer acceptance data undergo one-way ANOVA followed by LSD analysis. Results reveal that the second treatment (BG1) achieves superior scores in color, aroma, and taste. Additionally, bôh gadông roll cakes maintain satisfactory storage quality for up to two days when stored in airtight containers. These findings highlight the potential of bôh gadông flour in enhancing local culinary innovation. Future studies should explore its application in other snack varieties and include proximate testing to determine nutritional composition.

Abstract

Bird migration is a critical ecological phenomenon influenced by various factors such as temperature changes, food availability, and reproductive cycles. Understanding the dynamics of migratory bird populations within specific regions is essential for conservation efforts. This study aims to identify migratory bird species within Banda Aceh City, focusing on the phenomenon of overstaying migratory birds. Conducted between April and June 2022, data collection took place in several locations, employing the concentration count method. Descriptive data analysis was performed to catalog bird species, and the Shannon-Wiener index was utilized to assess biodiversity. Results revealed the presence of four shorebird species. The study underscores the importance of protecting migratory bird populations in urban environments and highlights the potential impacts of their loss or disruption. Joint conservation efforts are crucial to safeguarding these species, and favorable conditions may encourage some individuals from commonly migrating species to remain in urban areas.

Abstract

At the beginning of 2020, education in Indonesia implemented online learning to prevent the spread of Corona Virus Disease (COVID-19). Students who take part in online learning have an increasingly high interest in learning, and there are also students who, since online learning is carried out, have less interest in learning. The research aims to find out students' interest in participating in online learning with learning outcomes that are held in the Basic Culinary Subject of the Culinary Department Odd Semester Academic Year 2020/2021. Quantitative descriptive research approach, sampling with saturated sample technique. Respondents totaled 37 people, namely class XI students who took Basic Culinary Subjects. Questionnaire data collection techniques, observation, documentation, and report cards. Descriptive data analysis and prerequisite test or normality test and linearity test. The study found a positive relationship between interest in online learning and learning outcomes in Basic Culinary Subjects, with a Pearson correlation value of 0.155 significance level of 0.498 > 0.05. This means that there is no correlation between interest in participating in online learning and student learning outcomes in basic culinary subjects in the culinary department at SMK Negeri 1 Takengon. It was concluded that the relationship between interest in online learning and student learning outcomes in the Basic Culinary Subject of the Culinary Department for the 2020/2021 Academic Year is weak.

Abstract

Penelitian ini bertujuan untuk menguji struktur faktor dan validitas instrumen ketahanan mental pada siswa SMA. Metode yang digunakan adalah analisis faktor eksploratori (EFA) dengan sampel sebanyak 114 siswa SMA yang mengisi kuesioner 10 item ketahanan mental dengan skala Likert 5 poin. Hasil uji KMO sebesar 0,872 dan Bartlett's Test of Sphericity signifikan (p < 0,001) menunjukkan kelayakan data untuk analisis faktor. EFA mengungkap tiga faktor dengan nilai eigen > 1 yang menjelaskan 64,6% total varians. Faktor pertama dinamai Ketahanan Emosional (4 item, α=0,856), faktor kedua Motivasi Diri (3 item, α=0,823), dan faktor ketiga Regulasi Diri (3 item, α=0,801). Reliabilitas keseluruhan instrumen menunjukkan koefisien Cronbach's Alpha 0,879. Hasil penelitian membuktikan bahwa instrumen ketahanan mental memiliki struktur faktor yang valid dan reliabel untuk mengukur konstruk ketahanan mental pada populasi siswa SMA. Kata kunci: ketahanan mental, motivasi diri, regulasi diri, EFA
