Abstract The uncontrolled expansion of urban areas is one of the main factors that reduce the liveability of cities. In recent years, to contrast urban sprawl, several nations have promoted policies aimed at developing urban green spaces. The importance of green oases within cities had already been highlighted, in 1977, by the architect Christopher Alexander who had developed a series of patterns including ‘City Country Fingers’ claiming that city development should consider the prolongation of country land in to the urban area. In several cities, especially in Japan, it is possible to recognize the imprint of urban development based on country fingers. This term refers to extensive urban intersections of agricultural land or wooded hills which, from the peripheral areas, penetrate the city. Inside them, there are urban windows, called city fingers, whose development direction is opposite to those of the country fingers. To recognize and analyze, in an automated way, these particular structures, a Python-based application was created. Starting from the original high-resolution image of Google Earth, a complete analysis was performed, labeling and delimiting urban and vegetational areas and extrapolating the main geometric parameters of the country and city fingers. The finalization of the results obtained was carried out through a classification model whose criteria were based on Alexander’s pattern. Thanks to this classification scheme, the distinction between Active Green Areas (country fingers) and Passive Green Areas (gardens and public parks) have been revealed for the analyzed cities. The tests performed showed almost ideal conditions for the city of Kamakura and a limited match for the urban area of Acireale. The proposed method is suitable for fields of application that require a qualitative and quantitative determination of the vegetation cover present within the city, an essential condition for correct territorial planning.

AbstrakPT. TASS Engineering adalah perusahaan yang bergerak di bidang karoseri truk. Perusahaan ini bekerja sama dengan pihak kedua (pemborong) dalam menyelesaikan pekerjaan untuk memenuhi pesanan pelanggan. Diantara produknya, terdapat 4 jenis produk (Dump Truck, Subframe, Tilting, dan Tanki Truck) yang pengerjaannya diserahkan kepada 4 tim  pemborong. Keputusan alokasi pekerjaan dilakukan dengan cara memberikan pekerjaan kepada tim yang sudah menyelesaikan pekerjaan tertentu. Cara alokasi ini ternyata menimbulkan biaya tiap tim dalam mengerjakan satu jenis produk yang sama  cukup bervariasi. Variasi biaya pengerjaan tentu saja berdampak bagi variasi keuntungan. Perlu ditentukan alokasi jenis dan jumlah pekerjaan yang tepat bagi masing-masing tim sehingga mendapatkan keuntungan yang maksimum. Hasil alokasi optimum adalah parameter keputusan kombinasi jumlah produksi tiap produk selain kapasitas tiap tim dan waktu pengerjaan.. Kombinasi jumlah tiap produk ini merupakan target produksi atau target penjualannya. Untuk itu diperlukan penelitian yang bertujuan 1) menentukan alokasi pekerjaan yang optimum, 2) menentukan target produksi tiap produk untuk mendapatkan keuntungan maksimum. Alokasi pekerjaan dilakukan dengan membandingkan metode Penugasan Hungarian dan metode Transportasi untuk memilih total biaya yang paling minimum. Solusi optimum jumlah produk yang diproduksi untuk mencapai keuntungan maksimum dilakukan dengan Program Linier. Hasi temuan penelitian menunjukkan bahwa 1) dump truck dikerjakan sebanyak 88% oleh tim-1 dan 12% oleh tim-4; subframe dikerjakan sebanyak 39% oleh tim-2, 26% oleh tim-3, 35% oleh tim-4; tilting dikerjakan oleh tim-3, dan tanki truk dikerjakan oleh tim-2.

Solusi ini memberikan kenaikan keuntungan sebesar 0.9%.. Kata kunci: optimum, Hungarian, Transportasi, Program Linier AbstractPT. TASS Engineering is a company engaged in the truck body. The company is working with a second party (contractor) in completing jobs to fulfill customer orders. Among its products, there are 4 types of products (Dump Truck, Subframe, Tilting, and Tanki Truck) whose job is submitted to 4 teams of contractors. The decision on job allocation is done by givingit  to the team that have alredy completed their jobs. This allocation method turns out to cost each team to work on the same type of product that is quite varied. Variations in the cost of work, of course, have an impact on variations in profits. It is necessary to determine the allocation of the type and amount of work that is right for each team so as to get the maximum profit. The optimum allocation result is the decision parameter for the combination of the amount of production of each product in addition to the capacity of each team and the processing time. For this reason research is needed which aims to 1) determine the optimum allocation of work, 2) determine the production target of each product to get the maximum profit. The work allocation is done by comparing the Hungarian Assignment method and the Transportation method to choose the minimum total cost. The optimum solution for the number of products produced to achieve maximum profit is done by the Linear Program. The results of the research findings show that 1) dump trucks were handled by 88% by team-1 and 12% by team-4; subframes are done by 39% by team-2, 26% by team-3, 35% by team-4; tilting is done by team-3, and truck tank is done by team-2; 2)the production target (sales target) to get maximum profit is to produce 73 units of dump trucks, 120 units of subframes, 29 units of tilting, and 33 units of tank trucks. This solution provides a profit increase of 0.9%.Keywords: optimum, Hungarian, Transportation, Linier Programming
