Abstract

Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk menghasilkan strategi pembelajaran kimia pada materi termokimia dengan STEM Problem Based Learning yang valid, praktis dan efektif. Model pengembangan yang digunakan adalah model ADDIE (Analysis, Design, Development, Implementation, Evaluation) dan dievaluasi dengan metode evaluasi formatif Tessmer. Tahapan evaluasi formatif Tessmer dalam penelitian ini meliputi self evaluation, expert review, one-to-one dan small group. Pada tahap expert review validasi menggunakan masing-masing 2 pakar yakni ahli desain dan ahli pedagogik. Hasil tahap expert review melalui kesepakatan kappa diperoleh skor akhir validasi pedagogik memiliki nilai sebesar 0.64 (baik) dan validasi desain melalui kesepakatan kappa diperoleh skor 1 (sangat baik) dengan skor akhir rata-rata kevalidan sebesar 0.82 (sangat baik). Kepraktisan strategi pembelajaran dilakukan dikelas XI SMA N 19 Palembang. Skor kepraktisan one to one sebesar 4.46 dengan kategori sangat praktis. Skor kepraktisan small group sebesara 4.4 dengan kategori sangat praktis. Keefektifan ditunjukan oleh hasil ujicoba lapangan dari kelas ujicoba dan kelas biasa. Hasil nilai rata-rata kelas ujicoba 85.75 (keefektifan tinggi ) lebih besar dibandingkan kelas biasa 76.26. Berdasarkan hasil evaluasi tersebut menunjukan bahwa strategi pembelajara yang dihasilkan telah memenuhi kriteria yang valid, praktis dan efektif. Disarankan strategi pembelajaran ini dapat dijadikan salah satu alternative guru sebagai langkah untuk mengajar.

Abstract

Aquatic environment influences squid hatching rates. Hatching eggs is purpose to keep the availability stock squid. The research has been done in March – April 2017. This research aims to evaluate the effect of salinity for squid eggs hatching rate. The method used in this research was experiment. The research was in Aquaculture Hatchery, Faculty of Agriculture, Fishery and Biology of TheUniversity of Bangka Belitung. The squid eggs was from the the Sea of Riau Silip (Tuing village). The squid eggs data and hatching time were analyzed descriptively. Hatching Rate, mortality, increase of squid eggs and water quality were analyzed with ANOVA. The result showed that the fastest hatching time on the salinity was 32 g/l and the lowest salinity was 24 g/l . The Results of best hatching rate on the salinity was 28 g/l and 32 g/lwith the value of each salinity were 96 % ± 6,10 and 92,67 % ± 6,89. The squid larva mortality was highest at salinity 24 g/l with the value was 77,1 % ± 16,26 and The lowest on the salinity was 28 g/l with the value was 4,1 % ± 2,88.

Abstract

Perikanan dan Kelautan, Universitas Brawijaya3Dosen Fakultas Perikanan dan Ilmu Kelautan, Universitas Brawijaya.ABSTRACTAgricultural waste has problems on fiber and cellulose digestibility in its utilization foraquaculture. The ability of plant cellulose degrading bacteria to become a source ofenergy can increase the digestibility of feed by fish. The purpose of this study was toidentify the cellulolytic bacteria from the mangrove ecosystem, Tukak Sadai District,South Bangka Regency. This study was conducted in March until August 2017.Samples were taken from litter, mud and weathered wood and isolated usingCarboxymetyl Cellulosa (CMC) 1% media and found 22 bacterial isolates. Gramstaining results showed that 3 isolates (TSS 2, TSL 6 and TSK 4) were classified asgram positive and 19 other isolates were gram negative. Cellulolytic test results showed6 isolates had the ability to degrade cellulase, namely 3 isolates from mangrove mudsamples (TSS 1, TSL 7, TSL 1), 2 isolates from leaf litter (TSS 4, TSL 2) and 1 isolatefrom weathered wood (TSK 5) . Sequencing of 16S rRNA gene DNA showed proximityto Pseudomonas aeruginosa in TSL 7 and TSS isolates 4

Abstract

In Bangka Belitung Islands Province, squid (Urotheutis chinensis) is a non-fish category fisheries export commodity with a larger amount than other commodities. The high rate of ecosystem damage and high sedimentation of marine areas due to mining activities has caused squid catches in coastal areas to tend to decrease. Based on the research results, the Coral Reef Exploration Team of the University of Bangka Belitung, Tuing waters are a fisheries stronghold in Bangka Regency. This is evidenced by the absence of tin mining activities. The Universitas Bangka Belitung Community Service Program (KKN) in Tuing Hamlet, Mapur Village, Riau Silip Subdistrict, Bangka Regency began in 2014 and 2015 by starting activities to build squid attractor FADs. In 2016, this program was again focused on pioneering Bangka squid cultivation activities with additional programs in the form of developing local potential-based natural tourism potential and educational work programs to increase understanding for the community of the importance of preserving marine ecosystems.marine ecosystem. The results that have been carried out are the collection of squid eggs using a fisherman's net, then incubated in a maintenance aquarium that has been set up using a top filter. The successfully reared squid larvae were then released as a form of restocking activity. natural resources with related stakeholders. The next activity is to increase the potential of coastal tourism (beach) by promoting tourism through website development and building supporting facilities in the form of Saung (simple shelter) provided to all visitors to rest after climbing. can rest after the hike. Another ecotourism development is the coral reef transplantation program by involving the community to increase awareness of the importance of coral reefs in increasing fish biodiversity in Tuing waters. in Tuing waters. In addition to the community, other educational activities were carried out through teaching activities for students of SDN 11 Riau Silip in the classroom by providing exposure related to the topic of marine ecosystems. The educational presentation provided consisted of several topics, namely the introduction of marine ecosystems, the introduction of freshwater and marine biota, the impact of damage to marine ecosystems, and the introduction of the movement to love eating fish.

Abstract

Community service activities represent one of the implementations of the Tri Dharma of higher education, aimed at providing tangible contributions to society. This program was conducted in Bumi Nabung Ilir Village, focusing on improving educational literacy, financial literacy, digital literacy, and social awareness within the community. The program was motivated by several issues, including low literacy and numeracy skills among elementary students, limited understanding of financial literacy from an early age, insufficient awareness among adolescents in using digital media wisely, and a lack of reproductive health education for young women. Additionally, village development was supported through the construction of a hamlet monument as a regional identity. The activities were carried out using a participatory approach, including field observations, socialization, counseling, tutoring, practical activities, and the development of village facilities. The target groups included elementary and junior high school students, village youth, and the local community. The results indicate that the program had a positive impact, such as improved literacy and numeracy skills, increased awareness of saving from an early age, better understanding of responsible digital media use among adolescents, and enhanced knowledge of reproductive health among young women. The construction of the hamlet monument also strengthened regional identity and encouraged community participation in village development. Overall, this program demonstrates that collaboration between university students, educational institutions, and the community can effectively enhance educational quality and social awareness.
