Judul: Akurasi Sensor MODIS dan VIIRS dalam Mendeteksi Kebakaran Hutan dan Lahan di Kabupaten Muaro Jambi, Provinsi Jambi
Abstrak: Kabupaten Muaro Jambi merupakan kabupaten di Provinsi Jambi yang memiliki jumlah titik hotspot terbanyak dalam satu dekade terakhir. Penelitian bertujuan menganalisis akurasi sensor MODIS dan VIIRS dalam mendeteksi kebakaran hutan dan lahan di Kabupaten Muaro Jambi. Sumber yang digunakan adalah data sebaran hotspot dari sensor MODIS dan VIIRS di Kabupaten Muaro Jambi dan citra Sentinel-2. Hasil penelitian menunjukkan bahwa dalam rentang tahun 2019-2022, hotspot paling banyak ditemukan pada tahun 2019. Jumlah hotspot pada rentang tahun tersebut adalah 3.404 yang terdeteksi oleh sensor MODIS dengan akurasi sebesar 49,43% dan 15.015 yang terdeteksi oleh sensor VIIRS dengan akurasi sebesar 50,98%. Selang kepercayaan sedang (moderate) hingga tinggi (high) menunjukkan frekuensi tertinggi dalam mendeteksi kebakaran hutan dan lahan., Muaro Jambi District is a district in Jambi Province that has the highest number of hotspots in the last decade. The research aims to analyze the accuracy of MODIS and VIIRS sensors in detecting forest and land fires in Muaro Jambi Regency. The sources used are hotspot distribution data from MODIS and VIIRS sensors in Muaro Jambi District and Sentinel-2A imagery. The results of the research show that in the 2019-2022 period, the highest number of hotspots were discovered in 2019. The number of hotspots in that year was 3,404 detected by the MODIS sensor with an accuracy of 49,43% and 15.015 detected by the VIIRS sensor with an accuracy of 50,98%. The moderate to high confidence interval shows the highest frequency of detecting forest and land fires.

Judul: Analysis of Forest and Peatland Fire  Vulnerability in Muaro Jambi Regency, Jambi Province
Abstrak: Provinsi Jambi dikenal sebagai wilayah yang rentan terhadap kebakaran karena hampir setiap tahun wilayahnya mengalami insiden kebakaran pada lahan gambut yang memiliki luas cukup signifikan. Tujuan dari penelitian ini adalah untuk menganalisis distribusi dan jumlah hotspot, menganalisis korelasi antara curah hujan dengan hotspot sebagai indikator terjadinya kebakaran hutan dan lahan gambut, serta menganalisis kegiatan masyarakat terkait pembakaran hutan dan lahan gambut. Pemetaan sebaran hotspot dilakukan dengan analisis spasial data hotspot, sebaran lahan gambut, dan data administrasi Kabupaten Muaro Jambi. Data sebaran hotspot, dan curah hujan harian yang telah direkapitulasi kemudian dilakukan uji korelasi bivariate pearson menggunakan aplikasi SPSS. Wawancara secara in depth interview dengan jenis teknik sampling kuota yang telah disediakan untuk menentukan kegiatan masyarakat yang dapat memicu kebakaran. Distribusi hotspot di Kabupaten Muaro Jambi selama periode 2019- 2023 mencapai total 5974 titik. Hasil penelitiam menunjukkan bahwa hubungan antara curah hujan dan hotspot di Muaro Jambi tidak signifikan dan berkorelasi negatif yang berkategori sedang dengan nilai P value sebesar 0,493 > 0,05., Jambi Province is known as an area vulnerable to fires because almost every year it experiences fire incidents on peatlands, which have a significant extent. The purpose of this study was to i) analyze the distribution and number of hotspots, ii) analyze the correlation between rainfall and hotspots as indicators of forest and peatland fires, and iii) analyze community activities related to forest and peatland burning. Mapping of hotspot distribution was conducted using spatial analysis of hotspot data, peatland distribution, and administrative data of Muaro Jambi Regency. The distribution of hotspots and daily rainfall data that had been recapitulated were then subjected to bivariate Pearson correlation tests using SPSS software. In-depth interviews with a quota sampling technique were conducted to determine community activities that could trigger fires. The distribution of hotspots in Muaro Jambi Regency during the period 2019-2023 reached a total of 5,974 points.. The analysis shows that the relationship between rainfall and hotspots in Muaro Jambi is not significant and moderately negatively correlated, with a P-value of 0.493 > 0.05

Abstrak: The technology of fish testicular cells transplantation had been established to create a surrogate broodstock. This technology can also be utilized to generate YY-progenies that are useful to produce all-male fish. In this study, as a first step towards all-male tilapia production, white Nile tilapia testicular cells was transplanted into peritoneal cavity of triploid black tilapia larvae. A specific primer was designed to identify colonization and proliferation of transplanted cells in recipient fish using PCR method. Analysis of gonadosomatic index (GSI) was also performed to determine the transplanted cells proliferation in recipient gonad. The result of PCR analysis showed a specific DNA amplification product in the gonad of transplanted fish. The specific DNA donor was detected on the recipient gonad 90 dpt (days post transplantation) and it was not detected on 30 and 60 dpt. The GSI analysis showed that GSI recipient was increased and relatively similar with diploid non-transplanted Nile tilapia and it was higher than triploid non-transplanted Nile tilapia. These results showed that the donor cell could be colonized and proliferated in triploid black tilapia gonad. Thus, it is likely to obtain a broodstock that is able to produce donor-derived gamete in the near future.
