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: Development of smart tourism for tour in Srengseng Urban Forest of West Jakarta, DKI Jakarta.
Abstrak: Smart tourism adalah kegiatan wisata yang menggunakan kemampuan teknologi dan informasi dalam mengelola infrastruktur fisik maupun koneksi sosial. Hutan Kota Srengseng (HKS) merupakan kawasan hutan kota yang ditetapkan melalui Surat Keputusan Gubernur DKI Jakarta Nomor 202 Tahun 1995. HKS memiliki luas 15 ha berfungsi untuk konservasi keanekaragaman hayati, ruang aktivitas dan wisata masyarakat. Penelitian ini bertujuan untuk menganalisis potensi HKS untuk wisata, menganalisis persepsi, motivasi, dan preferensi pengunjung untuk pengembangan smart tourism dan merumuskan pengembangan program smart tourism untuk wisata di HKS. Metode pengumpulan data yang digunakan adalah observasi lapang, wawancara, kuesioner dan kajian pustaka. Kuesioner disusun menggunakan skala Likert dan hasil wawancara dianalisis menggunakan analisis SWOT. Hasil penelitian menunjukkan perlu dilakukan peningkatan fasilitas. Program seperti aplikasi terpadu MySrengseng App, virtual tour, voice assistant, smart content, dan mentor virtual dapat dikembangkan sebagai bagian dari smart tourism untuk wisata masyarakat di HKS., Smart tourism is a tourism activity that uses technology and information capabilities in managing physical infrastructure and social connections. Srengseng City Forest (HKS) is an urban forest area established through DKI Jakarta Governor Decree Number 202 of 1995. HKS has an area of 15 ha that functions for biodiversity conservation, activity space and community tourism. This research aim to analyze the potential of HKS for tourism, analyze the perceptions, motivations, and preferences of visitors for the development of smart tourism and formulate the development of smart tourism programs for tourism in HKS. The data collection methods used were field observation, interviews, questionnaires and literature review. Questionnaire was constructed using a Likert scale and the interview results were analyzed using SWOT analysis. Results showed that it is necessary to improve facilities. Programs such as MySrengseng App integrated application, virtual tour, voice assistant, smart content, and virtual mentor can be developed as part of smart tourism for community tourism in HKS.

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.
