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: 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: 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.
