Judul: Potential Location and Health Response of  Healing Forest in Bogor Botanical Gardens
Abstrak: Perkembangan teknologi telah menyebabkan peningkatan urbanisasi dan kepadatan penduduk yang dapat memengaruhi kualitas hidup dan kesehatan mental. Pemulihan kesehatan mental dapat dilakukan dengan memanfaatkan ekosistem hutan sebagai healing forest. Penelitian ini bertujuan untuk menentukan lokasi potensial dan respon kesehatan dari healing forest di Kebun Raya Bogor. Penentuan lokasi dilakukan dengan tiga tahap yaitu analisis spasial, pengukuran parameter biofisik lingkungan, dan pengukuran parameter kesehatan. Hasil penelitian menunjukkan Kebun Raya Bogor dapat dikembangkan sebagai lokasi healing forest dengan memilih kondisi pagi hari, karena kondisi pagi menunjukkan nilai yang paling ideal dibandingkan dengan kondisi waktu lainnya. Aktivitas healing forest dapat menurunkan tekanan darah, menurunkan denyut jantung, menurunkan tingkat stres, dan meningkatkan saturasi oksigen. Terdapat perubahan yang signifikan dari setiap respon kesehatan saat sebelum dan sesudah melakukan healing forest kearah ideal (p<0,05). Hal ini menunjukkan bahwa berinteraksi dengan alam dan menghabiskan waktu di hutan dapat memberikan manfaat bagi kesehatan fisik dan mental., The development of technology has led to increased urbanization and greater population density that can affect the quality of life and mental health. Mental health recovery can be achieved by utilizing the forest ecosystem as a healing forest. This research aimed to determine potential locations and health response of healing forest in Bogor Botanical Gardens. The determination of locations was done through three stages, which are spatial analysis, measurement of biophysical environmental parameters and measurement of health response. Results found that Bogor Botanical Gardens can be developed as healing forest site by selecting morning conditions, as the most ideal time. Healing forest activities can lower blood pressure, reduce heart rate, decrease stress levels, and increase oxygen saturation. There were significant changes in each health response before and after participating in the healing forest towards the ideal condition (p<0.05). This indicates that interacting with nature and spending time in the forest can provide benefits for both physical and mental health.

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: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
