Family-Friendly Kampong (FFK) Modelling: Developing Urban Resilience in Disaster-Prone Area

Family-friendly integrated and holistic development is the principal solution for many socio-cultural, economic, and ecological problems of marginal families lived in a disaster-prone area. This descriptive-qualitative study at Panaragan Village Bogor city, a hydrometeorology hazard area, has elaborated characteristics and vulnerability of family and community, areal typology, family and environment transaction, also social environment vulnerability and quality. Data were collected from interviews, focus group discussions (FGDs), and observation then analyzed with a gap, potential, and SWOT analysis. Results showed that Panaragan had shown features as FFK, characterized by high territorial-bound, well-maintained social capital and leadership (formal and informal) strengthened with organizational facilities, well perception about the family condition, also superior awareness of potential threat and vulnerability in family and community. With diverse topography, FFK model based in hamlet (RW) level. FFK development was done with positive-labeling, intrinsic spirit of community cohesiveness, a satisfaction of acceptance and recognition, social piety, volunteerism, and generosity. Derivative strategy of FFK model aimed to find competitive and comparative excellence of community productive activities, provide chances for elderly to be senior citizen, escalate community leaders and youth capacity, upgrade public figures and religious leaders’ leadership, maintain inter-family communication and interaction, preserve community leaders’ motivation, and disseminate social environment maintenance burden.     Keywords: ecology family, family-friendly kampong, family transaction, urban resilienc

Family Ecological Transaction for Disaster Risk Reduction: Case of Anak Dalam Tribe in Bukit Dua Belas National Park, Air Hitam Regency, Jambi, Indonesia

Anak Dalam Tribe (ADT) is an indigenous community living inside the conservation area, protected as cultural heritage. ADT family is highly dependent on the forest, they used to live and fulfill all their needs from the forest. Now with the modernization and regulatory dynamics taking place, ADT family undergoes changes as a form of adaptation, leading to residing categorization i.e. traditional, transition, and bediom. The changes impact on the ecological transactions thus bring a greater potential risk of forest fires, as has happened in recent years. This study aims to discover ADT family ecological transactions based on their residing type so that potential environmental exposure can be predicted and anticipated for disaster risk reduction. The qualitative research was conducted using a cross-sectional method. Data were collected through in-depth interview, observation, and forum group discussion. Mapping was done to understand the transaction pattern. This study found that the pattern of each kampong was different, showing that development has happened following the socio-ecological changes of each kampong, either by nature or intervention from outside parties. However, the livelihood area is still the biggest and outermost area of all six kampongs despite the residing type, covering the forest area. Moreover, the area of exposure is enlarged. It vindicates the escalating disaster risk. It is suggested to create a holistic livelihood ecosystem for ADT near their residing place to minimize the disaster risk. Political identity of ADT also should be reconsidered, with the inevitable global development, how far the heritage should be kept

Genomic insights into rapid speciation within the world’s largest tree genus Syzygium

Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift and hybridisation in the apportionment of genetic variation, remain poorly understood factors. Here, we study these aspects in a model radiation, Syzygium, the most species-rich tree genus worldwide. Genomes of 182 distinct species and 58 unidentified taxa are compared against a chromosome-level reference genome of the sea apple, Syzygium grande. We show that while Syzygium shares an ancient genome doubling event with other Myrtales, little evidence exists for recent polyploidy events. Phylogenomics confirms that Syzygium originated in Australia-New Guinea and diversified in multiple migrations, eastward to the Pacific and westward to India and Africa, in bursts of speciation visible as poorly resolved branches on phylogenies. Furthermore, some sublineages demonstrate genomic clines that recapitulate cladogenetic events, suggesting that stepwise geographic speciation, a neutral process, has been important in Syzygium diversification

Genomic insights into rapid speciation within the world's largest tree genus Syzygium

The relative importance of the mechanisms underlying species radiation remains unclear. Here, the authors combine reference genome assembly and population genetics analyses to show that neutral forces have contributed to the radiation of the most species-rich tree genus Syzygium. Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift and hybridisation in the apportionment of genetic variation, remain poorly understood factors. Here, we study these aspects in a model radiation, Syzygium, the most species-rich tree genus worldwide. Genomes of 182 distinct species and 58 unidentified taxa are compared against a chromosome-level reference genome of the sea apple, Syzygium grande. We show that while Syzygium shares an ancient genome doubling event with other Myrtales, little evidence exists for recent polyploidy events. Phylogenomics confirms that Syzygium originated in Australia-New Guinea and diversified in multiple migrations, eastward to the Pacific and westward to India and Africa, in bursts of speciation visible as poorly resolved branches on phylogenies.

Thin film nanocomposite (Tfnc) membranes: Future direction of Tfnc synthesis for alcohol dehydration

Polymeric membranes separation among the new and reliable separation and purification techniques in terms of energy consumption, ease of the process, and high selectivity due to polymer properties can be tailored to specific needs. This comprehensive review highlights polymeric membranes’ current development, specifically on thin film nanocomposite membranes for alcohol dehydration via pervaporation (PV). Discussion on substrate choice and fillers incorporating in respective polymers and how significant both materials in PV application has been scrutinized. Recent works on Thin Film Nanocomposite (TFNC) membranes showed that there is still a gap in factors or parameters involved in TFNC synthesis, which the same old weakness of membrane swelling, flux loss, and selectivity deficit seem left to be discovered. A performance plot of IPA dehydration from recent works has been provided within this paper as a benchmark for researchers to compare their findings. This review emphasizes on finding a set of parameter and nanomaterial as a possible approach for future TFNC development

Genomic insights into rapid speciation within the world’s largest tree genus [PREPRINT].

Species radiations have long fascinated biologists, but the contribution of adaptation to observed diversity and speciation is still an open question. Here, we explore this question using the clove genus, Syzygium, the world’s largest genus of tree species comprising approximately 1200 species. We dissect Syzygium diversity through shotgun sequencing of 182 distinct species and 58 additional as-yet unidentified taxa, and assess their genetic diversity against a chromosome-level reference genome of the sea apple, Syzygium grande. We show that Syzygium grande shares a whole genome duplication (WGD) event with other Myrtales. Genomic analyses confirm that Syzygium originated in Sahul (Australia-New Guinea), and later diversified eastward to the Hawaiian Islands and westward in multiple independent migration events. The migrations were associated with bursts of speciation events, visible by poorly resolved branches on phylogenies and networks, some of which were likely confounded by incomplete lineage sorting. Clinal genomic variation in some sublineages follows phylogenetic progression, which coupled with sympatric occurrences of distantly related species suggests that both geographic and ecological speciation have been important in the diversification of Syzygium. Together, these results point to a mixture of both neutral and adaptive drivers having contributed to the radiation of the genus
