Abstract

Dalam proses pengembangan perangkat lunak, setiap pengembang baik tim maupun perorangan bertujuan untuk dapat menghasilkan produk perangkat lunak yang berkualitas tinggi. Salah satu kriteria penting dari kualitas perangkat lunak adalah jumlah kesalahan (defect) yang ditemukan pada perangkat lunak tersebut. Perangkat lunak yang berkualitas tinggi harus memiliki jumlah defect yang minimal sehingga mampu menyediakan fungsionalitas bagi pengguna dengan tingkat usabilitas yang tinggi. Salah satu faktor penting yang berpengaruh signifikan terhadap kualitas produk perangkat lunak adalah kualitas software process yang dijalankan. Hal ini berlaku untuk proses pengembangan oleh tim maupun proses pengembangan yang dilakukan oleh software engineer perorangan. Software Engineering Institue (SEI) di Carnegie Mellon University (Amerika Serikat) telah mengembangkan metode Personal Software Process (PSP) untuk membantu para software engineer meningkatkan kualitas software process yang mereka jalankan. Selain itu, SEI juga mengembangkan Process Quality Index (PQI) yang dapat digunakan untuk mengukur kualitas software process yang dilakukan oleh para software engineer.  PSP membantu software engineer meningkatkan kualitas software process mereka melalui praktek – praktek yang mendukung  proses identifikasi dan perbaikan defect pada perangkat lunak sedini mungkin. Selain itu, PSP memberikan motivasi yang besar bagi software engineer untuk dapat lebih disiplin pada setiap tahapan software process yang mereka jalankan. PQI mengukur kualitas software process dengan menggunakan indikator berupa perbandingan lama waktu penyelesaian serta jumlah defect yang ditemukan pada setiap tahapan software process.

Abstract

The double-pass solar collector with porous media in the lower channel provides a higher outlet temperature compared to conventional single-pass collector. Therefore, the thermal efficiency of the solar collector is higher. The solar collector can be used for wide variety of applications such as solar industrial process heat and solar drying of agricultural products. A theoretical model has been developed for the double-pass solar collector. An experimental setup has been designed and constructed. Comparison of the theoretical and the experimental results have been conducted. Such comparisons include the outlets temperatures and thermal efficiencies of the solar collector for various design and operating conditions. Close agreement has been obtained between the theoretical and experimental results.Keywords: double-pass solar collector, porous media, theoretical, experimental, efficiency.

Abstract

Metode finite difference eksplisit adalah metode yang mudah diprogram dibandingkan metode finite difference implicit atau metode-metode numerik lainnya. Selain itu, metode eksplisit itu dapat digunakan untuk menyelesaikan persamaan panas (heat equation) linear dalam satu dimensi. Akan tetapi, metode eksplisit itu mempunyai sebuah kekurangan yaitu keterbatasan stabilitas dari penyelesaian numerik adalah sangat ketat. Oleh sebab itu, metode eksplisit itu tidak lagi termasuk daftar metode-metode numerik yang handal yang dapat digunakan untuk menyelesaikan persamaan-persamaan diferensial parsial.Oleh karena itu, maka diusulkan untuk menggunakan analisis wavelet Haar di dalam skema numerik dari metode eksiplisit untuk mengatasi kekurangan metode itu, yaitu keterbatasan stabilitas, dengan menjaga diskretisasi dari metode eksplisit agar tidak berubah. Kekurangan dari metode finite difference eksiplisit itu sudah dapat diatasi secara signifikan oleh analisis Haar wavelet yang tidak mempengaruhi logika metode asli yatiu metode eksiplisit. Kata kunci: metode finite difference eksplisit, persamaan panas

Abstract

It is a vital importance to analyze road traffic accidents in order to improve traffic security management. Currently, most of the traffic information analysis is limited to general statistical analysis, which is hard to explore the rules hiding in its dataset and also difficult to find the spatial distribution characteristics. This paper aims to analyze the road traffic accidents dataset based on data mining method of K-Means clustering and visualize the result as a map. Firstly, data are extracted for clustering road segments based on similar characteristics that lies on the dataset, i.e. the number of accidents, the number vehicles involved, and the number accidents’ victims. Secondly, the result of clustering are presented as a map that aims to assist the police officer in identifying and evaluating some black spot areas (accident prone areas) in a monthly period, hence monitoring the safety of highways users can be anticipated earlier.

Abstract

Menghilangkan waste dan mengoptimalkan penggunaan kontainer merupakan hal yang penting dalam proses pengiriman komponen impor yang dilakukan oleh divisi logistik impor. Proses di gudang bahan baku impor berawal dari unloading kontainer hingga penyimpanan pada rak shutter. Pengiriman dalam kemasan pallet kayu untuk komponen PIO non-regulasi menimbulkan permasalahan yaitu ruang yang tidak terpakai cukup besar karena kardus komponen tidak diperbolehkan menahan tumpukan pallet kayu dan membutuhkan proses mengemas ulang. Penggantian pengiriman kemasan pallet kayu menjadi pallet rangka besi harus dianalisis kelayakannya sehingga masalah tersebut dapat diatasi. Disamping itu pengiriman komponen PIO non-regulasi dapat menggenapi pola siklus returnable pallet besi yang selama ini tidak dapat berlangsung untuk impor center cap dan ekspor komponen Engine SUV. Cara pengalokasian ke pallet rangka besi berdasarkan dimensi kardus komponen setelah itu disimulasikan ke dalam gambar AutoCAD 3 dimensi. Dengan pengemasan pallet rangka besi diperoleh jumlah pallet rangka besi yang dipakai 46 unit. Efisiensi penggunaan kontainer mencapai 72,1%, kebutuhan kontainer berkurang 1 kontainer, dan penghematan waktu sebesar 15,3 jam.
