Judul: Analisis Kinerja Keuangan Pabrik Resiprene 35 PT Industri Karet Nusantara dan Implikasinya pada Pengembangan Industri Resin Karet.
Abstrak: Pabrik Resiprene 35 merupakan salah satu unit usaha PT Industri Karet Nusantara yang menghasilkan resin karet. Sebagai salah satu bentuk diversifikasi produk karet hilir, diperlukan suatu analisis yang menunjukkan prospek bisnis resin karet. Penelitian ini bertujuan menganalisis perkembangan dan kinerja keuangan Pabrik Resiprene 35 periode 2011-2016, serta merumuskan implikasinya bagi pengembangan industri resin karet. Alat analisis yang digunakan adalah analisis Trend, rasio keuangan, dan Du Pont. Hasil penelitian menunjukkan bahwa Pabrik Resiprene 35 memiliki kinerja keuangan yang sudah baik, khusunya pada rasio keuangan yang nilainya lebih baik dibandingkan dengan nilai rataan industri. Oleh karena itu, resin karet memiliki prospek sebagai salah satu bentuk divesifikasi produk karet hilir. Implikasi pengembangan yang dirumuskan antara lain melakukan strategi intensif, meningkatkan kinerja departemen pemasaran, membentuk departemen riset dan pengembangan, menggunakan jasa konsultan pemasaran, dan menghimpun dana investasi.

Judul: Analisis Pengendalian Mutu Produk Resiprene 35 dengan Pendekatan Six Sigma di PT Industri Karet Nusantara
Abstrak: Resiprene 35 merupakan resin yang berasal dari senyawa polyisoprene yang telah disiklisasi dengan bantuan pemanasan dan katalis yang sesuai. PT Industri karet nusantara merupakan perusahaan yang memproduksi Resiprene 35 di Indonesia. Tingginya tingkat kecacatan produk Resiprene 35 pada bulan Juni 2021 akan mempengaruhi biaya produksi, maka perlu adanya tindakan dalam pengedalian mutu. Tujuan penelitian ini adalah untuk menganalisis permasalahan utama dan mengidentifikasi faktor yang mempengaruhi dalam pengendalian mutu produk Resiprene 35 di PT Industri Karet Nusantara. Pengolahan data dilakukan menggunakan metode DMAIC (Define, Measure, Analyze, Improvement, Control) Six sigma, dengan hasil DPMO sebesar 11.884 dan nilai sigma sebesar 3,76. Faktor yang menjadi penyebab kecacatan produk berdasarkan setiap jenis kecacatan, yaitu kecacatan Appearance disebabkan kotoran yang menempel dan mengering pada permukaan tangki, kecacatan Colour disebabkan mutu bahan kimia tidak sesuai dengan spesifikasi, kecacatan Viscosity disebabkan memiliki kadar kandungan air yang sangat tinggi

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
