SPIDA: Abstracting and generalizing layout design cases

Abstraction and generalization of layout design cases generate new knowledge that is more widely applicable to use than specific design cases. The abstraction and generalization of design cases into hierarchical levels of abstractions provide the designer with the flexibility to apply any level of abstract and generalized knowledge for a new layout design problem. Existing case-based layout learning (CBLL) systems abstract and generalize cases into single levels of abstractions, but not into a hierarchy. In this paper, we propose a new approach, termed customized viewpoint - spatial (CV-S), which supports the generalization and abstraction of spatial layouts into hierarchies along with a supporting system, SPIDA (SPatial Intelligent Design Assistant)

Perancangan Self Propelled Container Barge (SPCB) Sebagai Alternatif Angkutan Container Pelayaran Pantura Untuk Daerah Jawa Timur

Pengangkutan kontainer melalui media transportasi darat pada jalur utara pada dewasa ini sudah sangat padat. Dengan kondisi insfrastruktur transportasi darat yang ada, beban yang diberikan oleh moda transportasi kontainer melebihi kekuatan yang dimiliki oleh insfrastuktur. Hal ini menyebabkan kerusakan dari insfrastruktur transportasi darat tersebut. Dampak yang paling terlihat dari kerusakan insfrastruktur transportasi darat ini adalah terjadi banyak kemacetan yang merugikan semua pengguna dari transportasi darat, termasuk pengangkutan kontainer. Pemindahan moda transportasi container darat ke laut adalah salah satu alternatif yang sangat baik mengingat jalur laut sepanjang pantura masih sepi. Jalur laut sangat minim akan terjadi kerusakan sehingga kemungkinan terjadi kemacetan kecil. Dalam tugas akhir ini dilakukan perancangan moda transportasi container lewat laut yang efektif yaitu Self Container Barge atau disingkat SPCB untuk beberapa daerah tujuan yang sudah ditentukan berdasar permintaan transportasi container ini

An Interesting Study of Capacity Improvement of a Shipyard in Myanmar

¾ Six shipyards are in operation under control of Engineering Department of Inland Water Transport. Among them, Dalla shipyard currently accounts for about 50 percent of repair work on ships owned by the Inland Water Transport (IWT). The efficiency of the shipyard, which is about 164 years old, is hampered by old equipment, including some from the WWII-era (Word War II). Now the shipyard needs to be upgraded to improve its current capacity in ship repair. In this study, we proposed two ways which are supporting facilities and re-layout shipyard to increase ship repair. This paper obtains two alternative layouts of shipyard. The first alternative layout does not change the existing layout of shipyard but steel plate warehouse are built. The second alternative changes the existing layout because machine shop and steel plate warehouse is too far from the slipways. The first and second alternatives renovate zone 5 shop, carpenter shop, pipe and boiler shop and repair slipways. The two alternatives have steel plate warehouse as well as the addition of two material handling equipment mobile crane and forklift. The second alternative re-locates new machine shop near the slip ways for better material handling and time consuming. The second alternative is the best alternative in terms of economically feasible, good flow of material and perfect of technical term and the most number of ship repairs. Then it can be improved capacity amount 1.43 times and docking time can be reduced from average 33 days to 27 days

Regression Models for Spatial Data: an Example From Gross Domestic Regional Bruto in Province Central Java

The important role of a region's transportation infrastructure strongly affects the economic growth of the region and tends to affect the surrounding areas. The effect is called spillover effect. The aim of the research was to recognize the direct effect and spillover effect (indirect) of transportation infrastructure on the economic growth in Central Java. To identify the spillover effects, it is necessary to recognize the different characteristics of each region which have the implications on the various transportation infrastructures at each region in Central Java. Therefore, the spatial modeling was conducted. In this study, the spatial modeling employed was Spatial Durbin Error Model (SDEM). The SDEM is another form of Spatial Error Model (SEM). It does not allow for lag effects of endogenous variables, but it allows for spatial error and spatial lag on exogenous variables in which it simplifies the interpretations on direct effects and spillover effect. According to SDEM estimates, the transportation infrastructures at the districts/municipalities in Central Java had no significant effect on the outputs at each region where the infrastructures were located and their neighboring districts/citie

FLEXURAL STRENGTH ANALYSIS OF LAMINATED BAMBOO SLATS (BAMBUSA ARUNDINACEA) FOR CONSTRUCTING A SMALL FISHING BOAT SHELLS

Because of the advantages of bamboo and the decreasing supply of teak, as a material for the construction of small Indonesian fishing boats, bamboo becomes an alternative substitute for teak as a common material to construct this type of boat. There are many bamboo species and populations in Indonesia which form the basis for selecting an advanced alternative material to construct fishing boats. This study discusses the mechanical properties of laminated bamboo slats, with a polyamide epoxy adhesive made by employing a manual cold press method. The type of bamboo used was the Bambusa Arundinacea variety that was greater than 3 years old. The bamboo laminate flexural strength was tested using the ASTM D 3043 Standard. The results of these tests revealed that the flexural strength of the laminated bamboo slats provided bending strengths of MOR and MOE values of 84.12 MPa and 18.04 GPa respectively. By using MOR and MOE values, and based on Bureau Classification of Indonesia (BKI), the shell thickness of 30 GT a fishing boat was calculated to be 25 -28 mm (bottom shell) and 19 -21 mm (side shell). These dimensions showed that the shell thickness can be reduced up to 33.3% when compared with teak (Tectona Grandis ) and the total volume of shell material to build a 30 GT of fishing boat, can be reduced by approximately 30%. The flexural strength of the bamboo slat laminate was shown to be 20% higher than 2nd class solid teak.</jats:p

Review of pattern matching approaches

AbstractThis paper presents a review of pattern matching techniques. The application areas for pattern matching are extensive, ranging from CAD systems to chemical analysis and from manufacturing to image processing. Published techniques and methods are classified and assessed within the context of three key issues: pattern classes, similarity types and matching methods. It has been shown that the techniques and approaches are as diverse and varied as the applications.</jats:p

Evaluation of Bilingual Mathematics Learning Program at Al-Azhar Islamic Middle School, South Tangerang

This study evaluates the bilingual mathematics learning program at SMP Islam Al-Azhar 25, South Tangerang. The evaluation model used is CIPP (Context, Input, Process, Product). Data collection techniques using interviews, observation, and document analysis. The evaluation results show that the bilingual mathematics learning program at SMP Islam Al-Azhar 25 South Tangerang has been running well. The program aims to follow the school's "globally competitive" vision. Facilities and infrastructure are categorized as very good, teachers have met the academic qualifications of undergraduate Mathematics Education, students have met the qualifications with tested students through the stages of entering the bilingual class, and the readiness of teachers and students of class VII is categorized as good, and the readiness of teachers and students of class VIII categorized as very good. The mathematics learning process uses the Bilingual Immersion type of learning, with a translation and transcription approach. The average score for daily assignments and tests is above the KKM (Minimum Completeness Criteria). The evaluation component has met the criteria for success, but some need to be improved and developed, such as the availability of a language laboratory and the development of bilingual classes from two classes to all classes so that there are no social gaps
