    IDENTIFIKASI PARAMETER OPTIMALISASI PENGGUNAAN AIR IRIGASI BERDASARKAN ANALYTICAL HIERARCHY PROCESS (Studi Kasus Daerah Irigasi Muara Jalai Kabupaten Kampar)
    (2013-06-20) Rahmi; Fauzi Manyuk; Sandhyavitri Ari
    Agriculture is an area that requires special attention, where food insecurity is often seen in Indonesia and the world at large. Food insecurity happen because agriculture is not handled well. Parameter optimalization is planned based on the decision-making system method of Analytical Hierarchy Process (AHP) which are : Technical, Economic, Environmental, and Social/Cultural. The results of the AHP analysis with the help of Expert Choice program 2000 found that the most influential criteria in optimizing the use of irrigation water is technical criteria. The percentage of some criteria are technical criteria 39.9%, economic criteria 36.0%, environmental criteria 15.9%, and the criteria of social/cultural 8.1%. In addition, sub-criteria that most affect the optimal use of irrigation water are the cost of development and rehabilitation work of irrigation channel, the performance of the channel, and cooperative farmer groups P3A, where the three sub-criteria above must be maintained well. While the sub-criteria which need to be improved are the presence of a water keeper, the availability of funds to finance the annual operation and maintenance of irrigation, as well as the condition and function of irrigation channel.

    Pengolahan Limbah Mengandung Asam Oksalat Dengan Metode Wet Oxidation Berkatalis CoSO4
    (2015-09-28) Chairul; Sulistyati, Is; Rahmi; Handayani, Sri
    Wet Oxidation (WO) merupakan salah satu metode pengolahan limbah secara kimia dengan menggunakan reaksi oksidasi fasa cair pada temperatur dan tekanan yang tinggi ((125 – 320 oC dan 5 – 20 bar). Penelitan ini bertujuan untuk mempelajari WO asam oksalat, pengaruh variabel proses dan kinetika reaksinya. Konsentrasi awal asam oksalat yang digunakan adalah setara dengan konsentrasi COD 1125 mg/L. Untuk mempercepat terjadinya reaksi digunakan CoSO4 sebagai katalis. Peralatan yang digunakan berupa otoklaf berpengaduk dirangkai dengan peralatan untuk mengalirkan oksigen, penangas minyak (oilbath) serta kran pengeluaran sampel dan purging. Operasi dilakukan secara semibatch. Variabel yang digunakan adalah temperatur 120, 130 dan 140 °C dan penggunaan katalis. Hasil penelitian menunjukkan penyisihan COD rata-rata pada masa start-up adalah 16% sedangkan saat proses WO ± 4%.

For male we found 50% high and 50% middle category but for female 87% high and 12,5% middle category, and both no body in low category. There is a significant different between the male and female students in naturalistic intelligence after processing and analyzing by t-test, therefore, it can be shown that the value of t. count is bigger than t. table (2,725 > 2,704). According to the result we recommended to educator to improve naturalistic intelligence with the correct method and strategy with their own characteristic.
