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: Analisis Sebaran Hotspot dan Area Terbakar di Kabupaten Muaro Jambi, Provinsi Jambi
Abstrak: Salah satu provinsi di Indonesia yang rawan terhadap kebakaran hutan dan lahan adalah Provinsi Jambi. Kabupaten Muaro Jambi merupakan kabupaten yang terbakar setiap tahunnya di Provinsi Jambi. Tujuan dari penelitian ini untuk menganalisis hotspot dan area terbakar di Kabupaten Muaro Jambi pada tahun 2015 dan 2019. Data yang digunakan berupa hotspot dan informasi spasial daerah terbakar dari citra satelit MODIS Terra/Aqua serta data curah hujan dari BMKG. Hasil penelitian menunjukan bahwa jumlah hotspot pada tahun 2015 adalah sebesar 2731, yang tersebar di lahan gambut 2558 hotspot. Tahun 2019 memiliki jumlah hotspot sebesar 3321 yang tersebar di lahan gambut 3225 hotspot. Kecamatan yang memiliki jumlah hotspot tertinggi yaitu Kecamatan Kumpeh dengan jumlah 5191 hotspot. Curah hujan terendah tahun 2015 dan 2019 berada di bulan September. Curah hujan bulan September tahun 2015 adalah 15,2 mm dan bulan September 2019 adalah 39,3 mm. Luas area terbakar di Muaro Jambi pada tahun 2015 mencapai 19.995,3 ha dan tahun 2019 mencapai 45.636,4 ha., Jambi Province is one of fire prone province in Indonesia. One of district in Jambi Province that experiences forest and land fires is Muaro Jambi. The objective of this study is to analyze hotspots and burned areas in Muaro Jambi Regency in the period of 2015 and 2019. The data used in this study are hotspots and spatial information on burned areas from MODIS Terra/Aqua satellite imagery and rainfall data from BMKG. The results showed that the number of hotspots in 2015 was 2731, with 2558 hotspots located on peatland. In 2019, hotspot numbers increased become 3321 hotspots, with 3225 hotspots located on peatland. The sub-district that has the highest hotspot number is Kumpeh with 5191 hotspots. The lowest rainfall in 2015 and 2019 was in September. The rainfall in September 2015 was 15,2 mm / month and September 2019 was 39,3 mm / month. The area burned in Muaro Jambi in 2015 reached 19.995,3 ha and in 2019 it reached 45.636,4 ha.

Judul: Kolonisasi dan proliferasi sel testikular ikan nila putih yang ditransplantasikan ke ikan nila hitam triploid
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.
