Judul: Aplikasi Penggabungan Poligon Menggunakan Web Framework Shiny pada Bahasa Pemrograman R
Abstrak: Di kalangan para pengembang di lingkungan geospasial, nama open source software R cukup dikenal dan populer untuk mengolah data spasial. Selain dimanfaatkan untuk analisis data, R juga bisa dimanfaatkan untuk mengimple- mentasikan teknik geoprocessing pada data spasial yang sedang diteliti atau dikembangkan. Salah satu kekurangan R adalah pengolahan data yang dilakukan harus melalui console sehingga menyulitkan pengguna yang tidak terlalu paham dengan script pemrograman. Salah satu solusinya adalah dengan memberikan sebuah antarmuka pada program R yang sudah dibuat dengan menggunakan framework Shiny. Penelitian ini bertujuan membangun sebuah antarmuka untuk operasi geoprocessing pada data spasial berbentuk poligon pada bahasa pemrograman R menggunakan framework Shiny. Penelitian ini berhasil mengembangkan sebuah aplikasi yang dapat melakukan operasi geoprocessing khususnya intersect, union, difference, dan exlusive or pada data spasial dalam bentuk shapefile dan sudah diujikan pada data contoh dan data real. Aplikasi yang dibangun berhasil menggabungkan dua buah poligon yang dimasukan oleh pengguna menggunakan operasi intersect, union, difference, dan exclusive or.

Judul: Aplikasi Rancangan Campuran Berbasis Web dengan R Shiny
Abstrak: Perangkat lunak R merupakan program komputasi statistika yang open-source dan free software. R tidak mudah digunakan untuk pengguna non-statistika. Alternatifnya adalah menggunakan R Shiny. R Shiny dapat membuat aplikasi berbasis web yang dapat digunakan tanpa melakukan penulisan program R. Aplikasi R Shiny dapat digunakan untuk berbagai macam analisis, salah satunya adalah perancangan percobaan. Salah satu metode rancangan percobaan adalah rancangan campuran. Rancangan campuran digunakan untuk formulasi dalam berbagai bidang, termasuk di bidang industri. Pada penelitian ini akan membangun aplikasi R Shiny berbasis web yang user friendly dengan metode model waterfall. Aplikasi yang dibangun diberi nama ARC (Aplikasi Rancangan Campuran). Hasil output ARC akan dibandingkan dengan aplikasi Minitab. ARC bisa digunakan untuk membangkitkan rancangan campuran, melakukan analisis data untuk rancangan campuran, serta membuat visualisasi hasil analisisnya. Aplikasi yang telah dibuat mampu menghasilkan keluaran yang sesuai dengan yang dibutuhkan untuk rancangan campuran. ARC dapat membangkitkan rancangan dasar dari rancangan campuran yaitu simplex-lattice design, simplex-centroid design, axial design, dan extreme vertex design. Analisis data dan plotting yang dihasilkan berdasarkan contoh menghasilkan output yang sama antara aplikasi Minitab dengan ARC., The R software is a statistical computation language that is open source and also a free software. R is not easy to use by non-statisticians. The alternative is using R Shiny. R Shiny can make web applications that can be used without coding in R. R Shiny web application can be made for any purpose, an example is for experimental design. A mixture experiment is one of the methods of experimental design. Mixture experiments are used in many fields, such as in industry. In this research a user friendly web based R Shiny application is made with the waterfall model. The aplication that was developed is called ARC. The outputs ARC are compared with the outputs from Minitab. ARC can be used to generate designs, analysis and plotting. ARC can put out an output that is what is needed for mixture design. The mixture designs that can be generated are simplex-lattice design, simplex-centroid design, axial design, and extreme vertex. Data analysis and plotting with a certain input produces similar outputs between Minitab and ARC.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
