This study aims to investigate the perceptions of Generation Z students about ideal learning after the pandemic in Indonesia. This research uses a qualitative design with a phenomenological approach. There were 30 students from 6 different campuses in Serang City, Banten, Indonesia, who used a purposive sampling technique as research participants. Data collection was carried out using semi-structured interviews, which were then analyzed using thematic analysis techniques. The findings of this study state that there are four main themes regarding ideal post-pandemic learning, namely: (a) learning that is not monotonous, (b) equal portions of theory and practice, (c) ideal learning managed by an ideal lecturer, and (d) the need for the application of blended learning. This research contributes to the current literature on designing ideal learning on campus after the COVID-19 pandemic.

Macrozoobenthos is a sedentary aquatic biota and is often used as a bioindicator for assessing water conditions. Therefore, this study aimed to investigate the species diversity of the macrozoobenthos and to analyze the heavy metal contamination in Faunus ater in the Rasian and Asahan estuaries in Aceh Province, Indonesia. The sampling was carried out in July 2022 on a squared transect of 1 m × 1 m for the collection of macrozoobenthos samples at random locations. The results showed that there were 17 macrozoobenthos species from both locations, of which 14 species were found in the Rasian River estuary and seven species in the Asahan River estuary. The diversity index of macrozoobenthos was in a moderate category. Terebralia sulcata had a higher density in the Asahan River, while F. ater had a higher density in the Rasian River. The results of the heavy metal analysis in the F. ater sample showed that this macrozoobenthos was contaminated by mercury, cadmium, and lead, of which the concentration of mercury exceeded the threshold limit, and they are, therefore, not safe for consumption.

The concept of national identity in the nation-state is influenced by ethno-cultural identity. However, the decline in understanding and awareness among the younger generation in Indonesia has led to a national identity crisis, especially in the border areas. This research becomes a pioneer study investigating the forms and teachers' involvement in strengthening students' national identities at the border areas. The ethnographic approach reveals the depth of teachers' involvement, including students and school communities on the Indonesia-Malaysia border. This study shows that teachers' involvement is mainly through cultural festival activities, in which ethno-cultural identities that contain knowledge of ethnic groups in Indonesia are introduced. The teacher's success brings psychological changes shown in students' awareness and behaviour. This study provides insights and solutions that can be used to reduce the impact of the crisis and reflect views related to national identity. As input, ethno-cultural identity is paramount to strengthen the concept of national identity in the nation-state, especially for the younger generation.

This study aimed to investigate whether communication patterns, peers' involvement and gender different can be the predictors of adolescent bullying behavior. This study involved 193 adolescents of grade 8 and 9 with the most adolescents of 14 years old who had filled in questionnaires. The results showed the prevalence of adolescent involvement in bullying which was 62.69%. Parental communication patterns have an OR = 1.64 (95% CI=0.87-3.09). Peers involvement in bullying behavior (OR=1.92; 95% CI=1.01-3.66). Adolescent girls were more involved in bullying behavior (59.59%) compared to adolescent boys (OR=3.32; 95% CI=1.69-6.54). Poor parental communication patterns, peers influence negatively predict to the bullying behavior in adolescent. Bullying is higher in boys than girls where as boys has a greater chance of bullying than girls. Therefore, bullying intervention programs are needed in schools.

Microplastic might be a small size of plastic that is directly released into the environment or the result of larger in size of plastic degradations. The presence and effect of microplastic have been reported globally. However, the existence of microplastic trapped in beach sediment of Nasi Island is limited. This research was conducted to analyse the type of sediment, abundance and type of microplastic polymer found in beach sediments in Nasi Island, Aceh Besar Regency, Aceh Province, Indonesia. Sampling was carried out in April 2022 at Nipah Beach and Alue Riyeung Beach in Nasi Island, Aceh Besar Regency. Sediment type was analysed by dry sieve method, using a stratified sieve shaker while the observation of microplastic and its polymer were identified by microscope and Fourier Transform Infrared Spectroscopy (FTIR), respectively. The results showed that the types of sediment at both beaches belonged to the sand type. There were three types of microplastics found, namely fragments, films, and fibres. The highest abundance of microplastics was found in a 0.063mm filter at Nipah Beach with an amount of 2651 Particles/Kg while the lowest was found in a 0.125mm filter with an amount of 8 Particles/Kg at Alue Riyeung Beach. As the polymer types, it is found that fragment type microplastics are likely to have PETE (Polyethylene Terephthalate) polymers, film type microplastics are likely to have PS (Polystyrene) polymer types and Fibre microplastics are likely to have LDPE (Low-Density Polyethylene) polymers.

The research in Aceh Jaya District identified nine turtle nesting beaches: Babah Kuala, Patek, Babah Ngom, Kuala Doe, Rigaih, Alue Piet, Nisero, Aroen Meubanja, and Seunebok Padang. Olive Ridley (Lepidochelys olivacea) and Leatherback (Dermochelys coriacea) turtles inhabit these coastal areas. Nisero beach, Kuta Tuha Village, Panga Sub-District, recorded the highest nest count (12 nests) with both Leatherback and Olive Ridley turtles. Seunebok Padang beach, Seunebok Padang Village, Teunom Sub-District, had the lowest count (2 Olive Ridley turtle nests). Aroen Meubanja beach is the only one with protected status, while the remaining eight face the threat of egg poaching. Unprotected beaches are at high risk, emphasizing the importance of conservation for sea turtle survival and the local economy, particularly through tourism development. Beyond Aceh Jaya, Indonesia features other significant sea turtle nesting sites, like Pangumbahan beach in West Java and Wairundi Island and Venu Island in West Papua Province. The study evaluates various beach characteristics, including width and slope, influencing sea turtle nesting activities. Sediment analysis reveals predominant medium sand textures in Aceh Jaya District, contributing to suitable nesting conditions and emphasizing the need for targeted conservation efforts.

Coral Trout (Plectropomus leopardus) is a species of grouper that is highly valued and the main commodity in Simeulue Regency. This research aims to identify the supply chain, calculate the value of fisheries production and the percentage of production of Coral Trout (Plectropomus leopardus) in the PiSiSi Simeulue MPA.

In developing countries like Indonesia, responsible agencies have yet to consider in-depth factors in building better teacher performance in secondary education. Contemporary educational research has explored the relationship between motivation and professional development on teacher performance. However, there needs to be more understanding of this relationship with family sociological conditions, levels of managerial support, and different working conditions. This research examines how motivation and professional development can determine teacher performance by involving these three conditions. This research involved 474 secondary education teachers voluntarily and with specific criteria profiles tailored to their needs. Data collection was assisted using a closed questionnaire with a four-point Likert scale, tested for validity and reliability. Structural Equation Modeling was used to analyze data through path analysis and bootstrap methods. The findings prove the importance of motivation and professional development supported by family sociological conditions, managerial support, and proportional workload in determining teacher performance. These results shed light on secondary education providers in strengthening professional development and simultaneously strengthening teacher motivation which has so far often been overlooked. The strategy used is to provide support in the managerial aspect to create work comfort and a proportional workload to make it easier for teachers to carry out technical development. Lastly, support and positive relationships from the family contribute to strengthening the teacher's mentality which leads to strengthening work motivation. In conclusion, teacher performance in secondary education can be optimal by carrying out self-development, strengthening motivation, proportional performance, in addition to managerial and family support in establishing mental health.

Polyethylene terephthalate (PET) plastic is the most widely used type of plastic that produces waste and causes various environmental and health problems. The treatment of PET plastic waste with chemically and mechanically recycling approaches still has shortcomings, so biological processing using microorganisms or enzymes has new potential. Two bacterial isolates from the Indonesian Culture Collection of National Research and Innovation Agency (InaCC, BRIN), namely isolate InaCC B538 and InaCC B947, were further observed for their potential in PET plastic degradation. Firstly, both isolates were determined by the molecular marker 16S rDNA. The potential of both isolates was measured with following method: 10 days of degradation using PET and PCL substrates, esterase enzyme activity assay, and observation of the PET plastic surface using Scanning Electron Microscope (SEM). Species identification was performed using DNA sequencing of 16S rDNA. InaCC B538 and InaCC B947 were closely related to Bacillus altitudinis TBMAX41 and Alcaligenes faecalis AN-13, respectively. InaCC B947 isolate has a better potential in degrading PET plastic and PCL with a degradation percentage of 0.32% for PET plastic and 3.22% for PCL film for 10 days, respectively, and esterase activity of 0.06 U/ml; while InaCC B538 did not cause weight loss of PET and 2.49% for PCL, respectively, with esterase activity of 0.04 U/ml. The degradation of PET plastic by the isolates InaCC B947 was able to cause damage to the plastic surface leading to the degradation of PET plastic. [ABSTRACT FROM AUTHOR]

Gallus varius, an indigenous bird species of Indonesia, demonstrates significant genetic diversity. The genetic diversity assessment in G. varius encompassed both mitochondrial DNA (mtDNA) and nuclear DNA, with the mtDNA analysis primarily centered on domain I of the control region. This study aimed to describe the genetic diversity and structure of G. varius inhabiting Java, Madura, Lombok and Sumbawa based on the middle-lower part of control region mtDNA. Genomic DNA was extracted from the calamus tip of feather, then the middlelower part of control region was amplified and sequenced using two pairs of primers. In the examined control region, spanning from 944 to 1,008 bp, 13 bp of nucleotide variation was observed, with nucleotide diversity at 0.0021. Between G. varius samples and the reference (NC_007238.1), a total of 7 haplotypes were identified, 5 unique and 2 shared haplotypes, with haplotype diversity at 0.7692. The substantial diversity of haplotypes in this study and two previous study suggests that the genetic diversity of G. varius has remained stable over the past two decades. Additionally, genetic distance data indicate there is multiple G. varius subspecies, and the haplotype network accentuates signs of population differentiation. [ABSTRACT FROM AUTHOR]
