    Provinsi Nusa Tenggara Timur (NTT) merupakan salah satu daerah endemis tinggi malaria. Penularan penyakit malaria dipengaruhi oleh tiga faktor penting yaitu host, agent dan lingkungan. Perilaku nyamuk An. barbirostris mencari mangsa dan pola menghisap darah sangat mempengaruhi proses penularan malaria. Nyamuk Anopheles barbirostris telah dinyatakan sebagai vektor malaria di Propinsi Nusa Tenggara Timur. Penelitian ini bertujuan untuk melihat perilaku menghisap darah Anopheles barbirostris. Penelitian dilakukan pada tahun 2010 di Kecamatan Kupang Barat, Kabupaten Kupang di tempat tambak ikan bandeng. Penangkapan nyamuk dilakukan pada siang hari dan malam dengan menggunakan umpan orang. Jenis penelitian adalah eksplorasi dengan pendekatan observasional dan rancang bangun survei terhadap nyamuk dewasa dan habitat perkembangbiakannya. Anopheles sp. yang ditemukan pada lokasi penelitian adalah An. barbirostris dan An. subpictus. Berdasarkan pengamatan yang dilakukan di lokasi penelitian Dusun Lifuleo, didapati bahwa nyamuk An. barbirostris ditemukan menghisap darah manusia pada siang hari. Keunikan perilaku menghisap darah pada An. barbirostris yaitu menghisap darah manusia setiap jam sepanjang hari (malam dan siang) dengan kepadatan yang berbeda-beda setiap jamnya. Kadar garam habitat diantara 4,2-5 permil sebagai habitat perkembangbiakan Anopheles barbirostris dan An.subpictus

    Gula merupakan komoditas strategis dalam perekonomian Indonesia. Konsumsi gula per tahun tidak kurang dari 3 juta ton. Upaya pengembangan industri gula sangat tergantung akan ketersediaan bahan baku yaitu tebu sebagai bahan baku utama. Tebu merupakan tanaman musiman dari salah satu komoditas tanaman yang dikembangkan dalam kawasan perkebunan dan menghasilkan produk akhir gula dan tetes. Kabupaten Jombang merupakan salah satu sentra produksi tebu yang ada di Provinsi Jawa Timur, yakni menempati urutan keempat. Produktivitas tanaman tebu dipengaruhi oleh berbagai faktor, tidak hanya jenis lahan, namun juga dalam penggunaan sarana produksi dan teknik dalam budidaya tanaman tebu. Penggunaan faktor produksi yang tidak efisien tersebut bisa dipengaruhi oleh pengaplikasian yang salah atau tidak sesuai dalam input produksinya yang justru akan menambah biaya produksi yang menyebabkan pendapatan petani semakin berkurang. Tujuan penelitian ini untuk menganalisis tingkat efisiensi teknis dan efisiensi skala dalam penggunaan faktor-faktor produksi pada USAhatani tebu lahan kering di Kabupaten Jombang. Metode analisis yang digunakan yakni dengan Data Envelopment Anaysis (DEA) dengan menggunakan aplikasi DEAP 2.1. Hasil penelitian untuk tujuan pertama yaitu, tingkat efisiensi teknis dengan menggunakan metode DEA menunjukkan bahwa terdapat 53 % atau 19 responden petani yang berada pada kondisi efisiensi secara teknis, sedangkan sisanya sebesar 47 % atau 17 petani responden yang berada pada kondisi inefisiensi secara teknis. Rata -rata nilai efisiensi teknis adalah 0.982, nilai ini memiliki arti bahwa rata-rata efisiensi penggunaan input adalah 98,2% yang berarti bahwa secara teknis penggunaan faktor – faktor produksi USAhatani tebu lahan kering belum mancapai tingkat full efisiensi (kurang dari 100%) tetapi sudah mendekati kondisi full efisiensi. Penyebab inefisiensi penggunaan faktor-faktor produksi tebu lahan kering di Kecamatan Bareng, Kabupaten Jombang adalah terlalu banyak jumlah input yang digunakan, secara keseluruhan input yang menunjukkan penggunaan berlebih dan harus dikurangi yakni pada input tenaga kerja, bibit, dan herbisida. Hasil analisis untuk tujuan kedua yaitu, tingkat efisiensi skala dengan menggunakan metode DEA menunjukkan bahwa Dari 36 responden (UKE), sekitar 53% atau 19 UKE memiliki skala CRS (constant return to scale), 25% atau 9 UKE memiliki skala DRS (decreasing return to scale) dan 22% atau 8 UKE berskala IRS (increasing return to scale)

    AbstractA balanced incomplete block design (BIBD) B[k, λ;v] is an arrangement of v elements in blocks of k elements each, such that every pair of elements is contained in exactly λ blocks. A BIBD B[k, 1;v] is called resolvable if the blocks can be partitioned into (v−1)(k−1) families each consisting of v/k mutually disjoint blocks. Ray-Chaudhuri and Wilson [8] proved the existence of resolvable BIBD's B[3, 1; v] for every v≡3 (mod 6). In addition to this result, the existence is proved here of resolvable BIBD's B[4, 1; v] for every v≡4 (mod 12)

    Painting is an important process in the automotive assembly to give more attractive appearance to the vehicles and to provide the layer of protection against corrosion and weathering. The objective of this paper is to identify and analyze the factors affecting the quality of painting process at Company RST’s Paint Shop. The paint shop was unable to perform the painting process satisfactorily and deliver the painted vehicle bodies as per customer specifications. The study concentrated on the fiber defect detected at Top Coat Area as the major problem of paint deficiency. Using activities like Genba investigation, data collection, trials and data analysis, the root causes of the problem were identified. Six Sigma DMAIC approach was utilized in conducting the improvement activities. Through designed experiments conducted to determine the best parameter setting of the spray gun used in the painting process, it was found that 3.5 bars for air pressure and 450 ml/minutes for fluid delivery resulted in the lowest paint defect. The use of Six Sigma DMAIC approach had succeeded in helping the company to minimize paint fiber defect per unit (DPU) from 10 to less than 3 DPU. The results from the study have provided an insight on successful deployment of DMAIC through application of its various statistical tools and techniques, and as the systematic problem-solving framework on solving actual industrial issues such as automotive painting problem

    This study was conducted to identify sources of technical efficiency among beef cattle farmers. This was investigated using the stochastic frontier production function which incorporates a model for the technical efficiency effect. Farm level survey data from 100 beef cattle farmers were obtained using well structured questionnaire. The parameters were estimated simultaneously with those of the model of technical efficiency effects. Asymptotic parameter estimates were evaluated to describe technical efficiency determinants by using the maximum likelihood estimation technique. Result reveal a mean efficiency of 0,77 implying that output from beef cattle fattening could be increased by 23 percent using available technology. Results further reveal that education, experience, number of cattle ownership and credit have significant impact on technical inefficiency. Keywords: technical efficiency, technical inefficiency, beef cattle fattening

    This study focused on fabrication of polyurethane (PU) foams and its composites based on hydroxylated bioepoxy (B) and petroleum based synthetic epoxy (E), crosslinker and wood fillers. The fabrication of foams: B and E with different wood filler size such as flake (L) and powder (P) on different composition ratios of 5%, 10%, 15% and 20%. The fabrication techniques used in this research are open moulding technique. The physical properties such as morphological pore structure and its homogeneity of wood filler distribution in foam polymer composites were measured. The effect of different size of wood filler loading in PU foam composites were analyzed and discussed in detail such as gelling time, main pore size, interconnected pore and struts thickness. The operatory conditions of in-situ PU foams synthesis were optimized using a design of experiment (DOE). The correlations between factors (X1, X2, X3) and the responses (Y1, Y2, Y3, Y4) for B, E as well as BL, BF, EL or EF foams were further analyzed using Minitab software
