Abstract

Mining activities will reduce species diversity, whereas forest reclamation would restore the species diversity, which was previously a forested area. This research was conducted in PT Bukit Asam area, in 6 locations, and in natural forest, as a comparison. The objective of this research was identifying biodiversity of plants and birds in a reclamation area which had different planting years through an approach of diversity indices of vegetation and birds (H'), index of species similarity of plants and birds, and leaf area index (LAI). Research results showed that secondary succession occurred in the reclamation area. The value of plant diversity index in reclamation area of 1995 planting year exhibited diversity values which approached that of natural forest, except for undergrowth vegetation. Index of plant species similarity between reclamation area and natural forest did not show any presence of similar communities, but the reclamation area of 1995 planting year exhibited values of plant species similarity indices at all strata, ranging from undergrowth vegetation, seedlings, saplings, poles, and trees. Index of bird diversity in reclamation area of planting the year 1998 possessed the highest value and approached that of natural forest, namely 2.43. Reclamation area of 1998 planting year possessed the highest similarity index of bird species, namely 50%. Reclamation area of the planting year 1995 possessed LAI which approached natural forest, namely 1.89.  The older the planting year, the larger was the value of LAI, except for the disturbed reclamation area, namely reclamation area of 1996 planting year and reclamation area of 2001 planting year.

Abstract

Global warming is the increase temperature of the atmosphere, ocean and terrestrial ecosystem that lead to global climate change. The global warming caused by the increase of atmospheric green house gases (GHGs), such as CO2, SOx, NOx and CH4. Deforestation will cause the increase of atmospheric GHGs, meanwhile reforestation will lowering atmospheric GHGs. In urban environment, Urban Open Space instead of enhance the aesthetical aspect of town, it also contribute to atmospheric carbon absorbtion through photosynthesis process and store the carbon in the form of biomass. The objectives of this research are to determine the potential of carbon stocks and analyze the relationship between LAI with potential carbon stocks in trees, Basal area, stand density at Tahura Pancoran Mas, Depok.  Biomass of trees and woody nekromass calculated based on allometric equations, the calculated carbon content of 47% of the biomass. Carbon stocks potential in Tahura Pancoran Mas, Depok was 33,92 Mg/ha or carbon stocks potential with an area of 6 ha was 203,52 Mg C. The result of regression analysis shows that a relationship between LAI with stand density has the strongest relationship than the other. Selected regression model to estimate LAI is the stand density = -10,2 + 227 LAI with R2 is 0.60 and has a value of accuracy is 12,08%. Keywords: carbon stocks, LAI, stand density

Abstract

Abstrak: Salah satu tanaman TOGA yang umum ditemukan di desa-desa adalah serai, yang memiliki potensi besar untuk diolah menjadi produk bernilai guna, seperti spray anti nyamuk. Spray anti nyamuk berbahan dasar serai dipilih karena kandungan aktifnya, seperti sitronelal, geraniol, metilheptenon, terpen, alkohol terpen, dan asam organik, yang efektif sebagai pengusir nyamuk. Tujuan pengabdian ini meningkatkan pengetahuan kelompok sadar wisata tentang pengembangan produk TOGA spray anti nyamuk dari serai. Metode yang digunakan berupa pelatihan, diskusi, dan evaluasi monitoring. Mitra pengabdian ini pemerintah desa dan kelompok sadar wisata di Desa Rambah Samo Barat dengan partisipasi 36 peserta. Sistem evaluasi dilakukan dua bentuk, yaitu melalui pre-test dan post-test selama kegiatan pengabdian. Hasil pengabdian ini peningkatan pengetahuan tentang produk TOGA, kemampuan teknis pembuatan produk, keaktifan dalam sosialisasi, dan peningkatan pengetahuan wisata. Mayoritas 90% peserta tahu tentang manfaat produk TOGA spray anti nyamuk serta 90% memahami manfaat produk dalam mendukung wisata.Abstract: One of the TOGA plants commonly found in villages is lemongrass, which has great potential to be processed into valuable products, such as anti-mosquito spray. Lemongrass-based anti-mosquito spray was chosen because of its active ingredients, such as citronellal, geraniol, methylheptenone, terpenes, terpene alcohols and organic acids, which are effective as mosquito repellents. The aim of this service is to increase the knowledge of tourism awareness groups about the development of TOGA anti-mosquito spray products from lemongrass. The methods used are training, discussion and monitoring evaluation. The service partners are the village government and the tourism awareness group in West Rambah Samo Village with the participation of 36 participants. The evaluation system is carried out in two forms, namely through pre-test and post-test during service activities. The results of this service are increased knowledge about TOGA products, technical abilities in making products, activeness in socialization, and increased tourism knowledge. The majority, 90% of participants, knew about the benefits of the TOGA anti-mosquito spray product and 90% understood the benefits of the product in supporting tourism.

Abstract

Lingkungan memiliki peran penting dalam mendukung kesehatan mental manusia, di mana hutan dinilai sebagai tempat terapi alami yang efektif dan terjangkau. Salah satu bentuk terapi alam yang dikenal adalah Forest Healing, yaitu aktivitas menyatu dengan alam hutan untuk meningkatkan kesehatan fisik, mental, dan emosional. Penelitian ini bertujuan untuk menganalisis potensi Taman Hutan Raya (Tahura) Gunung Kunci di Sumedang sebagai lokasi Forest Healing berdasarkan karakteristik lingkungan hutannya. Parameter yang digunakan mengacu pada SNI 9006:2021, meliputi kerapatan vegetasi, suhu, kelembapan, tingkat kelerengan, dan tingkat kebisingan. Data dikumpulkan dari tiga lokasi utama: amfiteater, gardu pandang, dan bunker. Hasil penelitian menunjukkan bahwa kerapatan vegetasi tergolong rapat dengan dominansi pinus yang menghasilkan senyawa terpen bermanfaat bagi pernapasan. Kelembapan berada dalam kisaran ideal (68%) dan tingkat kebisingan tergolong rendah (<40 dB). Meskipun suhu rata-rata melebihi standar kenyamanan (27,4°C) dan beberapa titik memiliki kelerengan curam, kondisi tersebut masih dapat ditoleransi selama pengunjung dalam kondisi fisik sehat. Dengan demikian, Tahura Gunung Kunci memiliki potensi tinggi sebagai lokasi Forest Healing, dengan waktu terbaik pelaksanaan pada pagi hari. Hasil ini mendukung pengembangan wisata hutan berbasis terapi di Jawa Barat..
