    PEMANFAATAN SUMBERDAYA AIR DAN KALENDAR TANAM MENDUKUNG PENINGKATAN INDEKS PERTANAMAN PADI DI KABUPATEN BENGKALIS
    (2019-11) Fahri, Anis; Yusuf, Rachmiwati; Hidayat, Taufik
    Palm oil is one of the leading commodities agriculture sector in the plantation subsector, the existence of national private large plantations is a trigger for the presence of surrounding community gardens. The problem faced by smallholder oil palm farmers in the Upper Kampar River Basin is low productivity which results in low income of farmers due to high input prices and cheap output prices and far market access. The research objective is to find a model for the development of community oil palm plantations that function as conservation by implementing GAP. The method used is the Location Quotient (LQ) to analyze the export capacity of a region's economy and the level of adequacy of goods / services from a region's local production and spatial analysis to analyze the suitability of spatial and land suitability. The hypothesis is that community oil palm plantations in the upper Kampar watershed are not feasible to be developed because they are not suitable in terms of spatial suitability, land slope, land availability, market availability, difficult access to financial institutions

    Pengaruh Kadar Karbon pada Bahan Baku Pembuatan Katalis ZSM-5 dan Uji Kinerja Katalis pada Catalytic Slurry Cracking Tandan Kosong Sawit
    (2013-05-04) Sunarno; Zahrina, Ida; Reni Yenti, Silvia; Hidayat, Taufik
    Keterbatasan jumlah minyak bumi dan meningkatnya penggunaan minyak bumi sebagai akibat dari meningkatnya kebutuhan akan energi menjadi alasan utama pentingya mencari sumber energi alternatif yang dapat diperbaharui. Biomassa berupa tandan kosong sawit yang melimpah terdapat di Indonesia, khususnya Riau, dapat diproses menjadi bio-oil melalui proses catalytic cracking. Penelitian ini bertujuan untuk mempelajari pengaruh kadar karbon dalam sumber silika terhadap pembentukan katalis ZSM-5 untuk proses catalytic cracking tandan kosong sawit. Kadar karbon dalam sumber silika yaitu sebesar 2%, 4% dan 6% dari massa sumber silika. Pembuatan katalis ZSM-5 dilakukan di dalam autoclave pada suhu 175 0C selama 18 jam. Katalis yang terbentuk kemudian dicuci untuk membersihkan katalis dari sisa bahan kimia yang tidak bereaksi. Selanjutnya katalis dikalsinasi pada suhu 500 0C selama 6 jam untuk mengaktifkan katalis tersebut. ZSM-5 yang terbentuk selanjutnya dikarakterisasi luas permukaannya dengan metoda BET dan diuji kinerjanya dengan proses catalytic cracking tandan kosong sawit menjadi bio-oil. Selanjutnya bio-oil yang diperoleh dianalisa densitas, viscositas dan titik nyalanya. Dengan metoda BET diketahui luas permukaan katalis terbesar pada sumber silika dengan kadar karbon 6%. Namun katalis yang memiliki kinerja paling baik, yaitu menghasilkan yield yang paling tinggi yaitu katalis dengan sumber silika yang mengandung karbon sebesar 4% massa sumber silika.

    Studi Kandungan Logam Pb, Cu dan Zn pada Lapisan Sedimen yang Berbeda di Perairan Pantai Telaga Tujuh Kabupaten Karimun Kepulauan Riau
    (2013-04-23) Hidayat, Taufik
    The research was conducted in August 2012, by taking samples from Telaga Tujuh Coastal Waters District of Karimun in the province of Kepulauan Riau. This research aimed to obtain information about the distribution of the metal content of Pb, Cu and Zn in the sediments both horizontally and vertically, as well as to determine the level of metal pollution in Telaga Tujuh Coastal Waters due to the abandoned tin mining and anthropogenic activity around the area. The average content of heavy metals Pb, Cu, and Zn in the coastal waters of Telaga Tujuh are 60.76 μg/g, 38.24 μg/g and 108.41 μg/g, respectively. Average metal content of Pb, Cu and Zn are different betwean the upper layer (0-1 cm), middle layer (10-11 cm) and lower layer (20-21 cm). The highest metal content were found in the upper layer (0-1 cm), Pb 65.78 μg/g, Cu 49.12 μg/g and Zn 128.69 μg/g, which are related to the current input from anthropogenic activitis. Upper part of the sediment (0-1 cm) are the fastest layer influenced by heavy metal deposition than others coming from anthropogenic activitis around the Telaga Tujuh Coastal Waters.
