Abstract

Balai Latihan Kerja (BLK) merupakan lembaga pelatihan yang dibutuhkan bagi masyarakat di Provinsi Papua Tengah. Pembangunan BLK ditujukan untuk mempersiapkan masyarakat di Provinsi Papua Tengah untuk menjadi tenaga kerja lokal kompeten dan profesional dalam menghadapi persaingan tenaga kerja asing. Penelitian ini bertujuan untuk mengetahui kelayakan pembangunan BLK dengan mempertimbangkan aspek ketenagakerjaan, demografi, geografi, ekonomi, hukum, sosial budaya, ilmu pengetahuan dan teknologi, dan manajemen. Penelitian ini dilakukan di Distrik Wanggar Kabupaten Nabire. Hasil penelitian meliputi dominasi pekerja di sektor informal, jumlah penduduk terus meningkat, lokasi BLK berada pada dataran rendah, bangunan BLK merupakan bangunan gedung milik negara, BLK menjadi sarana pemberdayaan masyarakat, pengembangan sektor basis untuk mendukung pembangunan BLK, penggunaan teknologi virtual reality dan augmented reality pada simulator, dan pembukaan kejuruan di BLK Provinsi Papua Tengah mempertimbangkan potensi lokal serta kebutuhan pasar kerja, dengan fokus pada pertanian, perikanan, teknik, industri kreatif, teknologi informasi, dan kesehatan. Kesimpulan pembangunan BLK layak dilakukan dengan 7 parameter yang dianalisis, di lokasi Distrik Wanggar Kabupaten Nabire, Provinsi Papua Tengah.

Abstract

Public space is a place where people can carry out their various activities. Urban public space also represents the desire of urban communities to interact with their environment. The development of the form of utilization of public space is dedinitely goes hand in hand with an increase in activity, in terms of type and intensity. The purpose of this study is to find the factors that influence the utilization of active public space on Ijen Street Corridor and Jakarta Street corridors using the Factor Analysis. The results for the factors who affects the utilization of public open space is the experience to interact with another invididual person/doing something together, and the elements that are designing of the site in public space triggering an active attachment feeling to public space in Ijen Street Corridor. While in Jakarta Street Corridor, the results are comfort level of rest by the visitors when doing their activities in the public space, achievement of the criteria of being a good public space, the experience of interacting with another users, and the level of comfort for doing some activities at the public space.

Abstract

Rapid urbanization escalated domestic vehicular CO₂ emissions, necessitating the optimization of urban green open spaces (GOS) as engineered biological sinks. However, urban planning practices frequently prioritized spatial area over species-specific sequestration capacity, leading to potential spatial inefficiencies. This study evaluated the efficacy of four GOS in Tanjung Redeb, Indonesia, by overlaying localized vehicular emission loads—calculated using the Vehicle Kilometer Traveled (VKT) model—with the biological sequestration capacities of the parks, quantified through species-specific allometric equations. The results indicated that all evaluated parks operated at a net positive carbon surplus, with absorption ratios ranging from 1,474.8% to 117,668.6%. Crucially, the empirical data exposed a severe source–sink decoupling. The primary emission hotspot, Taman Bukit Maritam (1,032.33 kg CO₂/year), relied on moderately performing vegetation, yielding the lowest relative surplus. Conversely, the highest sequestration capacity (37,010.96 kg CO₂/year) was located in Taman Sanggam, a low-stress corridor (92.33 kg CO₂/year), driven by the aggressive structural biomass of the hyper-accumulator Samanea saman. The analysis demonstrated that biological filtration performance was strictly dictated by species taxonomy and allometric structure, rather than stand age or total park area. The study concluded that mitigating urban vehicular emissions required a paradigm shift from passive aesthetic landscaping to active, data-driven biological engineering, deploying high-capacity hyper-accumulators strategically along high-emission transportation corridors.
