Judul: Forest Healing: A Systematic Review on Forest Ecosystem Services Utilization as Alternative for Communities Stress Management
Abstrak: Pemanfaatan jasa ekosistem hutan melalui intervensi forest healing sangat memungkinkan dikembangkan di Indonesia mengingat terjadi peningkatan stres pada masyarakat Indonesia, sementara di sisi lain terdapat potensi hutan yang melimpah. Sebagai langkah awal pengembangan forest healing di Indonesia, telaah sistematis terhadap studi terdahulu perlu dilakukan dengan tujuan untuk mengidentifikasi: 1) karakteristik intervensi forest healing; dan 2) bukti empiris efektivitas forest healing dalam mengelola stres. Tahapan telaah sistematis ini meliputi studi literatur, ekstraksi data, sintesis dan analisis data. Berdasarkan studi literatur, 58 artikel layak untuk ditelaah. Hasil telaah dapat diidentifikasi bahwa: 1) konten intervensi forest healing yang paling banyak digunakan adalah berjalan di hutan dengan pembatasan aktivitas subjek untuk memaksimalkan respon terapi. Penentuan lokasi terapi pada kawasan hutan perlu memperhatikan kriteria biofisik lingkungan dan pengelolaan hutan untuk memenuhi standar kenyamanan; serta 2) forest healing terbukti efektif dalam mengelola stres berdasarkan analisis terhadap parameter uji dan respon psikologis. Adopsi terhadap model ini perlu dilakukan karena potensi kebermanfaatan yang besar bagi masyarakat., Utilization of forest ecosystem services through forest healing programs is possible to develop in Indonesia, given the increasing stress case, while on the other hand, there is huge potential of forest. As a first step in developing forest healing in Indonesia, a systematic review needs to be carried out to identify: 1) the characteristics of forest healing interventions, and 2) empirical evidence of the effectiveness of forest healing in managing stress. The stages of this systematic review include literature study, data extraction, and data analysis. Throughout literature study, 58 articles deserve to be reviewed. The results of the review can be identified that: 1) the content of the forest healing intervention that is most widely used is walking in the forest with restrictions on the subject's activity to maximize the therapeutic response. Determination of the location of therapy in forest areas needs to pay attention to environmental biophysical criteria and forest management to meet the comfort, and 2) forest healing is proven to be effective in managing stress based on an analysis of parameters and psychological responses. The adoption of this model needs to be done due to the huge benefits for the community.

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: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
