Judul: Smart Tourism Development in Pesanggrahan Sangga Buana Urban Forest, South Jakarta for Recreation
Abstrak: Hutan kota merupakan salah satu bentuk ruang terbuka hijau yang berada di tengah perkotaan. Penggunaan teknologi informasi dan komunikasi berbasis smart tourism merupakan faktor yang penting dalam pengadaan fasilitas di area rekreasi. Penelitian ini bertujuan mengobservasi kondisi potensi, pengelolaan hutan kota, serta preferensi pengunjung dan masyarakat sekitar, menganalisis fasilitas berbasis smart tourism, dan menyusun rekomendasi pengembangan berbasis smart tourism untuk rekreasi. Metode pengumpulan data yang dilakukan adalah studi pustaka, observasi lapang, kuesioner, dan wawancara. Analisis data yang digunakan adalah deskriptif kualitatif, tingkat capaian responden, dan SWOT. Hutan Kota Pesanggrahan Sangga Buana (HKPSB) memiliki potensi pengembangan fasilitas berbasis smart tourism untuk rekreasi masyarakat kota. Rekomendasi pengembangan berupa mengoptimalkan potensi, memaksimalkan kerja sama pengelola, meningkatkan promosi HKPSB, serta mengoptimalkan koordinasi antara pengelola., Urban forest is a form of green open space in the middle of an urban area. The use of information and communication technology based on smart tourism is an important factor in providing facilities for recreational areas. This study aimed to identify potential resources, management carried out on the urban forest, and preferences of visitors and the surrounding community, analyze facilities based on smart tourism, and formulate recommendations for development based on smart tourism for recreation. Data collection methods used were literature studies, field observation, questionnaires, and interviews. The data analysis used were qualitative descriptive, respondent achievement level, and SWOT. Pesanggrahan Sangga Buana Urban Forest (PSBUF) has the potential to develop smart tourism-based facilities for recreation. Recommendations for the development of facilities are optimizing potential, maximizing management cooperation, increasing PSBUF promotions, and optimizing coordination between managers.

Judul: Landscape Management of Gelora Bung Karno Urban Forest as a Recreation Area in Post Pandemic Era at DKI Jakarta
Abstrak: Hutan Kota GBK merupakan salah satu ruang terbuka hijau (RTH) terbaru yang dibangun di DKI Jakarta. Namun, kondisi Hutan Kota GBK saat ini masih memerlukan evaluasi dan kajian lebih lanjut, terutama terkait pengelolaan lanskapnya sebagai kawasan rekreasi di era pasca pandemi COVID-19. Tujuan penelitian ini adalah menganalisis pemanfaatan, potensi dan kendala, mengevaluasi aspek pemeliharaan dan pengelolaan, serta memberikan rekomendasi pengelolaan lanskap Hutan Kota GBK. Metode yang digunakan dalam penelitian ini adalah pengamatan lapang serta mempertimbangkan persepsi dan preferensi pengguna Hutan Kota GBK melalui metode analisis SWOT. Berdasarkan kajian ini, pemanfaatan Hutan Kota GBK merupakan ruang terbuka hijau sebagai sarana rekreasi. Masyarakat biasanya menggunakan Hutan Kota GBK sebagai tempat piknik, olahraga, live music atau acara publik, dan kegiatan rekreasi lainnya. Hasil penelitian ini juga menunjukkan bahwa kondisi Hutan Kota GBK saat ini termasuk ke dalam kuadran 5 pada Matriks Internal-Eksternal. Hal ini menunjukkan strategi pengelolaan yang direkomendasikan adalah strategi hold and maintain berupa penetrasi pasar dan pengembangan produk dalam bentuk placemaking. Kegiatan pengelolaan yang direkomendasikan adalah fokus pada optimalisasi fasilitas dan potensi Hutan Kota GBK, memperbanyak jenis dan jumlah vegetasi, mengembangkan teknik pemasaran digital, serta lebih memperhatikan keamanan dan regulasi terhadap protokol kesehatan., Hutan Kota GBK is one of the latest built green open space in DKI Jakarta. However, the current condition of the Hutan Kota GBK still requires further evaluation and study, especially regarding the management of its landscape as a recreation area in the post-COVID-19 pandemic era. The purpose of this study is to analyze the utilization, potential and constraints, to evaluate maintenance and management aspects, and also to provide recommendations for the management of the Hutan Kota GBK landscape. The method used in this study is considered the perceptions and preferences of Hutan Kota GBK users through the SWOT analysis method. Based on this study, the utilization of Hutan Kota GBK is a recreational green open space. People usually use Hutan Kota GBK as a place for picnics, sports, music or public events, and other recreational activities. The result of this study also indicate that the current condition of Hutan Kota GBK is included in 5th quadrant at Internal-External Matrix. It means the recommended management strategy is a hold and maintain strategy in the form of market penetration and product development with placemaking theory. The recommended management activities are focus on optimizing the facilities and potentials of the Hutan Kota GBK, enrich the type and amount of the vegetation, and paying more attention to security and regulations towards the health protocols.

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.
