Rimpang Lengkuas (Alpinia galanga L.) merupakan tanaman yang telah banyak digunakan sebagai rempah dan obat tradisional dalam kehidupan sehari-hari. Tanaman ini mengandung senyawa bioaktif flavonoid yang memiliki efek antioksidan. Penelitian ini dilakukan untuk mengetahui pengaruh ketinggian tempat tumbuh terhadap aktivitas antiokasidan dan toksisitas dari ekstrak rimpang lengkuas (Alpinia galanga L.). Ekstraksi dilakukan dengan cara maserasi sedangkan kadar polifenol dan flavonoid total dilakukan dengan menggunakan metode Folin-ciocalteu dan metode kolorimetri yang dianalisis dengan menggunakan alat spektrofotometer UV-Vis. Uji aktivitas antioksidan dilakukan dengan menggunakan metode DPPH (2,2-Difenil-1-Pikrihidrazil) dan sitotoksisitas dengan menggunakan metode BSLT (Brine Shrimp Lethaly Test). Ekstraksi menggunakan pelarut etil asetat diperoleh rendemen sebesar 2,24% untuk dataran rendah,  3,51% dataran sedang dan dataran tinggi sebesar 3,77%. Analisis kadar fenolik dan flavanoid diperoleh berturut turut dari dataran rendah ke tinggi sebesar 6,08±0,26% dan 2,25±0,05%, 5,09±0,14% dan 1,09±0,08, 5,47±0,24% dan 1,16±0,3%. Aktifitas antioksidan yang tertinggi diperoleh pada dataran rendah diperoleh IC50 332,48 bpj, kemudian pada dataran tinggi dengan IC50 447,14 bpj dan pada dataran sedang diperoleh IC50 sebesar 518,57 bpj. Uji sitotoksik terhadap ketiga ekstrak menunjukkan hasil LC50 yang tidak terlalu berbeda antara ketiga lokasi tersebut.

The status of a Special Allotment Forest Area (KHDTK) was obtained by the Forestry Education and Training Center of the Makassar Environmental and Forestry Education and Training Center in accordance with the Decree of the Minister of Forestry No. 041/Kpts/DJ/I/1980 on February 28, 1980 and the zoning by the Minister of Forestry No. SK.13 / Menhut-II / 2010 on January 14, 2010. The main function is to support the educational activities. Several forms of activities and utilization have been carried out in this area, including Research and Development, Nature Tourism, Environmental Services and non-timber forest products (NTFPs). Related to its main function as a means of supporting education, all the training activities, especially aspects of skills, are directed at KHDTK.Since established, KHDTK has numerous conflicts with the community. However, all existing conflicts have been acted on and a number of solutions have been made to resolve the existing problems. Regional stakeholders have managed the risks with a variety of activities, such as community empowerment, fostering the farmer groups, provision of assistance and facilitation as well as pre-emptive, preventive and repressive activities that are carried out routinely in the hope of aware the people, so that the KHDTK will receive recognition from the surrounding community.

The Covid-19 pandemic poses a threat of forest destruction, especially forest fires, along with the increase of intensity of humans entering and exploring the forest. It is suspected that many people who live in urban areas have lost their jobs due to layoffs and moved to villages, and then opened new lands because their supporting facilities were no longer relevant to the current conditions, the COVID-19 pandemic. These people who abruptly start their activities in the forest and do not understand the rules of preventing forest fires are making the forests vulnerable to fires. The purpose of this study was to determine the effect of the COVID-19 pandemic on the dangers of forest and land fires in South Sulawesi. It used a descriptive method, and data was collected through in-depth interviews with communities that are affected by the COVID-19 pandemic and live around the fire-prone forest areas. The results of the observation were processed by descriptive analysis to get the conclusion. The results showed that about 72% of the affected people are carried out activities in forest areas which 78% of them did not understand the rules of forest and land fire hazards. The results of this study will be recommended to the government, particularly to the policymakers in controlling forest and land fires, especially during the Covid-19 pandemic.
