Judul: The Potential of Healing Forest Area On the Darmaga Campus of IPB
Abstrak: Healing forest menjadi kegiatan yang populer pada masyarakat perkotaan pada saat ini khususnya yang sedang mengalami stres atau sekedar untuk mencari ketenangan diri di daerah hutan kota. Kegiatan healing forest memberikan efek relaksasi pada tubuh, menenangkan pikiran dan memberikan perasaan nyaman yang berimplikasi pada penurunan tingkat stres pada tubuh. Penelitian ini bertujuan untuk menginventarisasi potensi biofisik untuk kegiatan healing forest di masing-masing spot/area, mengidentifikasi aktivitas healing forest yang dapat dikembangkan di masing-masing spot/area serta melakukan penataan area untuk keperluan healing forest pada hutan kampus IPB Darmaga. Metode yang digunakan dalam penelitian ini adalah survei lapang dan wawancara terhadap masyarakat kampus IPB. Data yang diperoleh selanjutnya dianalisis menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan terdapat tiga lokasi yang layak yaitu Arboretum Lanskap, Hutan Bambu dan Arboretum Lanskap. Kegiatan yang dapat dilakukan berdasarkan analisis lokasi dan preferensi masyarakat adalah berjalan-jalan di hutan, memeluk pohon serta menikmati suasana alam yang ada., Healing forest becoming a popular activity in urban communities at this time, especially those who are stressed or just to find peace of mind in urban forest areas. This activities provide a relaxing effect on the body, calm the mind and provide a comfortable feeling which has implications for reducing stress levels in our body. This study aims to take an inventory of the biophysical potential for healing forest activities in each spot/area, identify healing forest activities that can be developed in each spot/area and to organize areas for healing forest purposes in the forests of IPB Darmaga campus. This research use a field survey method and interviews with the IPB campus community. Data obtained were analyzed using a qualitative descriptive method. The results showed that there were three feasible locations, namely the Landscape Arboretum, Bamboo Forest and Landscape Arboretum. Activities that can be carried out based on location analysis and community preferences are walking in the forest, hugging trees and enjoying the natural atmosphere.

Judul: Development of Healing Forest at Bedengan Campground and Sengkaling Recreational Park
Abstrak: Kepadatan penduduk di perkotaan menyebabkan timbulnya stress pada seseorang dan karenanya membutuhkan lingkungan yang mendukung untuk pemulihan, memberikan ketenangan dan kenyamanan. Konsep pemanfaatan hutan sebagai penyembuhan atau bisa disebut healing forest kini menjadi sebuah tren baru di dunia. Penelitian ini bertujuan mengkaji potensi biofisik healing forest di Bumi Perkemahan Bedengan dan Taman Rekreasi Sengkaling. Metode yang digunakan yaitu melakukan survei lapang, wawancara, dan melakukan studi litelatur. Setalah itu, data diolah dan dianalisis menggunakan metode deskriptif kualitatif dan mengkomparasikan dengan kriteria healing forest menurut SNI 9006:2021. Hasil penelitian menyebutkan bahwa Bumi Perkemahan Bedengan dapat dijadikan area healing forest, sedangkan pada Taman Rekreasi Sengkaling masih perlu adanya pengembangan dibeberapa potensi biofisiknya karena tidak memenuhi kriteria. Kegiatan healing forest yang dapat dilakukan seperti berjalan menelusuri hutan dan menikmati pemandangan. Kedua lokasi yang berpotensi sebagai area healing forest dapat dikembangkan dengan cara menigkatkan pengelolaan dan penataan wilayah dengan baik, serta pemeliharaan tapak., Urban population density causes stress and therefore raises necessitates a supportive environment for recovery, providing tranquility and comfort. The concept of using forests for healing, known as healing forests, has become global trend in recent. This research aims to assess the biophysical potential of healing forests at the Bedengan Campground and Sengkaling Recreation Park. The methods used include field surveys, interviews, and literature studies. The data is then processed and analyzed using qualitative descriptive methods and compared with the healing forest criteria according to SNI 9006:2021. The research concludes that Bedengan Camping Ground can be designated as a healing forest area, while Sengkaling Recreational Park requires further development in certain biophysical aspects as it doesn't meet the criteria. Healing forest activities include walking through the forest and enjoying the scenery. Both potential locations can be developed through proper land management and further research on site development as healing forest areas is needed.

Judul: Estimation of Additive and Non-Additive Genetic Variances of Body Weight, Egg Weight and Egg Production for Quails (Coturnix coturnix japonica) with an Animal Model Analysis
Abstrak: This study estimates the additive and non-additive variances for egg production and body weight traits of two lines of quails from a long-term selection with the help of the REML method. For the body weight of 42-day-old females (BW42f) and males (BW42m), a total of 7,934 records for line 1 and 7,214 records for line 2 from 21 generations were used in our analyses. Additionally, 1,717 records of females from line 1 and 1,671 records of females from line 2 contained information on their egg production at an age of 42 to 200 days (EN200), on the average egg weight for the first 11 weeks of their laying season (EW1), on the average egg weight from weeks 12 to 23 (EW2), and on their body weight at an age of 200 days (BW200f). A multivariate additive animal model and one-trait dominance models, which include the inbreeding coefficients as covariates, were fitted to the data. The estimates of the heritability gained from our dominance models were smaller than those from the additive model. For line 1, the heritability values decreased for EN200 from 0.35 to 0.32, for EW1 from 0.66 to 0.56, for BW200f from 0.42 to 0.38, and for BW200m from 0.51 to 0.49, respectively. For the first line, the respective ratio (d2) of the dominance variance to the phenotypic variance for EN200, EW1, BW200f and BW200m was 0.08, 0.22, 0.09 and 0.21, and the values for the second line were 0.12, 0.06, 0.001 and 0.23.
