Penelitian bertujuan menganalisis perilaku masyarakat yang dapat memicu terjadinya kebakaran gambut dan menganalisis persepsi dan tingkat pengetahuan masyarakat terhadap pengendalian kebakaran gambut di Desa Tangkit Baru. Analisis data penelitian dilakukan secara deskriptif melalui wawancara menggunakan kuisioner yang berisi 20 pernyataan positif mengenai pengelolaan lahan gambut yang berkelanjutan, dampak dari kebakaran gambut, serta langkah pengendalian kebakaran gambut dari partisipasi masyarakat menggunakan skala likert. Hasil analisis perilaku masyarakat yang dapat memicu terjadinya kebakaran gambut pada lokasi penelitian di lahan gambut merupakan kegiatan sonor, pembersihan lahan dengan pembakaran, dan membakar sampah. Persepsi dan tingkat pengetahuan masyarakat terhadap pengendalian kebakaran gambut termasuk dalam kategori tinggi dan memiliki korelasi hubungan yang sangat kuat. Hubungan antara pengetahuan dan persepsi masyarakat di Desa Tangkit Baru memiliki korelasi positif., Muaro Jambi Regency, which has a peat distribution area of 229,703.90 ha, often experiences forest and land fires, especially in Tangkit Baru Village, Sungai Gelam District, where most of the area is peatland. The research aims to analyze community behavior that can trigger peat fires and analyze community perceptions and level of knowledge regarding peat fire control in Tangkit Baru Village. Research data analysis was carried out descriptively through interviews using a questionnaire containing 20 positive statements regarding sustainable peatland management, the impact of peat fires, as well as steps to control peat fires from community participation using a Likert scale. The results of the analysis of community behavior that can trigger peat fires at research locations on peatlands are sonor activities, land clearing by burning, and burning rubbish. The community's perception and level of knowledge regarding peat fire control is in the high category and has a very strong correlation. The relationship between knowledge and community perception in Tangkit Baru Village has a positive correlation.

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: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
