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: 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

Judul: Optimization of Alginate-Chitosan Microcapsules Formation for Leydig Cells Encapsulation
Abstrak: Hypogonadism is a clinical condition characterized by low concentrations of testosterone. It is caused by malfunction of Leydig cells in producing testosterone. Encapsulation method will protect the transplanted cells from the immune system rejection. The aims of this study was to optimize the formation of microcapsules for Leydig cells encapsulation. The microcapsules were made of alginate and chitosan as the first and the second coating agents, respectively. The result showed that the minimum concentration of alginate was 1.5% (w/v) with a viscosity of 33.8 cPs, resulted spherical microcapsules with diameters of 230-270 µm. The optimum concentration of chitosan as the second coating agent was 0.5% (w/v), resulted spherical microcapsule with mechanical stability in 4 hours. Leydig cells can be trapped inside the capsule with a density that proportional with concentration of cells used in the encapsulation.
