Perancangan Algoritma Penjadwalan dan Pengurutan Produksi di PT. Upayakita Arunggaplasindo

Dewasa ini, persaingan dalam druria industri sangat ketat dan tiap perusahaan berusaha untuk memberikan kepuasan kepada konsumen dalam bentuk service yang memuaskan, harga barang yang murah, kualitas produk yang baik dan penyelesaian pesanan tepat pada waktunya. Semua itu dilakukan perusahaan untuk menjaga kepercayaan konsumen sehingga tidak kecewa dan beralih ke produk perusahaan lain. P.T. Upayakita Annggaplasindo adalah perusahaan yang menghasilkan produk peralatan rumah tangga dari plastik, dimana kursi plastik merupakan produk andalannya. Aliran proses produksi pembuatan kursi termasuk dalam tipe flow shop dan produksi dilaksanakan dengan sistem job order. Selama ini, perusahaan serirg mengalami keterlambatan dalam memenuhi pesanan konsumen karena belum adanya aturan penjadwalan produksi dan biasanya produksi didasarkan berdasarkan perkiraan semata dengan aturan First Come First Serve. Oleh karena itu, perusahaan memerlukan aturan penjadwalan dan pengurutan produksi untuk meminimumkan keterlambatan tersebut. Pada Tugas Akhir ini diberikan alternatif penjadwalan dan pegurutan produksi untuk meminimumkan jumlah tugas yang terlambat sehingga perusahaan dapat mengurangi keterlambatan dalam memenuhi pesanan konsumen. Berdasarkan studi kasus yang dijadwalkan menggunakan algoritna penjadwalan dan pengurutan produksi yang dirancang dihasilkan pengurangan jumlah tugas yang terlambat dari 7 tugas menjadi 4 tugas. Dengan demikian terjadi pengurangan jumlah tugas yang terlambat sebesar 42.86 % dan penjadwalan ini menghasilkan jadwal produksi dengan waktu penyelesaian tugas yang lebih awal daripada metode First Come First Serve

The dominant Anopheles vectors of human malaria in the Asia-Pacific region: occurrence data, distribution maps and bionomic précis

<p>Abstract</p> <p>Background</p> <p>The final article in a series of three publications examining the global distribution of 41 dominant vector species (DVS) of malaria is presented here. The first publication examined the DVS from the Americas, with the second covering those species present in Africa, Europe and the Middle East. Here we discuss the 19 DVS of the Asian-Pacific region. This region experiences a high diversity of vector species, many occurring sympatrically, which, combined with the occurrence of a high number of species complexes and suspected species complexes, and behavioural plasticity of many of these major vectors, adds a level of entomological complexity not comparable elsewhere globally. To try and untangle the intricacy of the vectors of this region and to increase the effectiveness of vector control interventions, an understanding of the contemporary distribution of each species, combined with a synthesis of the current knowledge of their behaviour and ecology is needed.</p> <p>Results</p> <p>Expert opinion (EO) range maps, created with the most up-to-date expert knowledge of each DVS distribution, were combined with a contemporary database of occurrence data and a suite of open access, environmental and climatic variables. Using the Boosted Regression Tree (BRT) modelling method, distribution maps of each DVS were produced. The occurrence data were abstracted from the formal, published literature, plus other relevant sources, resulting in the collation of DVS occurrence at 10116 locations across 31 countries, of which 8853 were successfully geo-referenced and 7430 were resolved to spatial areas that could be included in the BRT model. A detailed summary of the information on the bionomics of each species and species complex is also presented.</p> <p>Conclusions</p> <p>This article concludes a project aimed to establish the contemporary global distribution of the DVS of malaria. The three articles produced are intended as a detailed reference for scientists continuing research into the aspects of taxonomy, biology and ecology relevant to species-specific vector control. This research is particularly relevant to help unravel the complicated taxonomic status, ecology and epidemiology of the vectors of the Asia-Pacific region. All the occurrence data, predictive maps and EO-shape files generated during the production of these publications will be made available in the public domain. We hope that this will encourage data sharing to improve future iterations of the distribution maps.</p

Exon prediction on DNA-genes of Plasmodium falciparum based on coding sequence structure using hidden Markov model

BACKGROUND A hidden Markov model (HMM) is used for exon prediction on DNA of genes Plasmodium falciparum that has a model structure based on exon region structure in coding sequence (CDS). The objective research was to develop a new structure model to predict exon on DNA-genes of Plasmodium falciparum based on CDS structure using the HMM system. METHODS Model design in CDS, between two exon regions can be found one intron region and the model state number is used for its region. Its state number is used by separating start codon from first exon region and stop codon from the last exon region up to 9. The Viterbi algorithm and the backward-forward method for transition as well as emission states are used for training process. Furthermore, Viterbi and Baum-Welch algorithms are used for the testing process. The correlation coefficient (CC) was used as performance indicator, as the ratio of the estimated state in the output and the original state in the input of the model. RESULTS The simulation results has shown that the CC values depend on the given of the backward-forward transition state values randomly. The model with state number 9 showed the highest average of CC values of 0.7289 for Viterbi algorithm, and is 0.7166 for Baum-Welch algorithm. However, the lowest average of CC values has been found for the model with state number five. Its values are 0.6735 by using Viterbi algorithm and 0.6661 by using Baum-Welch algorithm. CONCLUSION The new structure model based on HMM system was valid to predict exon on DNA-genes of Plasmodium falciparum

INTESTINAL AND BLOOD PARASITES OF MAN IN TIMOR

Survey tinja dan darah dipulau Timor guna menentukan distribusi dan prevalensi penyakit parasit diantara penduduk telah dilakukan pada bulan Juli dan Agustus tahun 1972 sebagai kelanjutan dari deretan survey yang dilakukan oleh Direktorat Jenderal Pencegahan Pemberantasan Penyakit menular Departemen Kesehatan, Bagian Parasitologi dan Pathologi Umum Fakultas Kedokteran Universitas Indonesia dan US Namru-2 di Indonesia. Sejumlah 445 sediaan tinja untuk pemeriksaan parasit usus, 581 sediaan darah untuk pemeriksaan parasit malaria dan 663 sediaan darah untuk pemeriksaan parasit filaria telah diambil dari penduduk cara merata di 7 desa pada 3 kabupaten di Timor, Nusa Tenggara Timur. Enam puluh delapan per cent diantara penduduk melihatkan satu atau lebih parasit usus didalam tinjanya dimana cacing tambang merupakan parasit usus yang terbanyak. Ascaris lumbricoides ketemukan jauh lebih kurang daripada di Jawa, Sumatra dan Sulawesi, juga diketemukan perbedaan itara "intestinal parasite rate" di Timor Indonesia dan Timor Portugis. Dua belas percent penduduk yang diperiksa melihatkan parasit malaria didalam darahnya sedangkan parasit filaria ditemukan sebanyak 8 percent. Plasmodium falciparum merupakan parasit malaria yang terbanyak ditemukan, ia jenis parasit fdaria yang ditemukan adalah "Timor microfilaria" dan Wuchereria bancrofti dimana yang pertama merupakan parasit yang terbanyak diantara penduduk yang diperiksa
