Peran Pemerintah Daerah Provinsi Riau dalam Pengelolaan DAS Siak: Studi Kasus Daerah Hilir DAS Siak Tahun 2010-2013

This reseacrh is aimed to figure out how is the role of Riau Province Local Governmenton Siak Watershed Management (known as Daerah Aliran Sungai, DAS). It is focused to thedownstream watershed of Siak River area considering to the most complex problem exists on it.Those problems consist of domestic waste, industry waste, residential issue. The role of localgovernment on DAS management especially for downstream area is based on main duty and thefunction of each related government Departement. On this management there are no specificregulation in DAS management area. Based on this background, the research is aimed toanalyze the role of Local Government in the Province of Riau on DAS management that isfocused on the downstream of DAS.The type of this reseacrh is description, which means the researcher gives a descriptionor illustration about related phenomenon or social symptom which is analyzed by describingindependent variable systematicly and accurately. Data collection method is done by IndepthInterview and documnetation study.The result of analysis shows that the role of local government on DAS management ofdownstream is based on TUPOKSI (Tugas Pokok dan Fungsi) of each Departement.Departement of Living Environment (known as Badan Lingkungan Hidup, BLH) has a role onmanaging industry waste, domestic waste, Departement of Public Project (known as DinasPekerja Umum, PU) Riau Province Resicence Division has a role on resident management.While cooperation of each Departement is needed on DAS management.Keywords: Role, Local Government, River Stream Distric

Collaborative Govenance in Preserving the Malay Culture of Riau

The Riau Government is committed to preserving the Riau Malay Culture as stated in the Riau Vision 2025. The current facts show that there is a severe weakening of the Malay Culture in Riau Province. This can be seen from the ethics, grammar, Fashion, culinary, art, and Malay traditions that the Riau Malay community is starting to leave. The purpose of this study was to determine collaborative governance in the effort to preserve the Riau Malay Culture. The research method used is qualitative. The results of this study indicated that the Riau Government is not committed to achieving its vision, which is reflected in government policies. Lack of a roadmap for a cultural vision so that a network structure between stakeholders was not formed, the master plan owned by each stakeholder was not integrated, and was not interdependent, did not have a standard measure that describes procedures and authority in action, there was no function of joint decision-making and sharing of responsibilities, and there was no communication and flow of information between stakeholders so that collaborative governance in the preservation of Riau Malay culture was not carried out

The Pengaruh Pemberian Ragi Roti dengan Dosis yang Berbeda terhadap Kepadatan Rotifera (Brachionus Plicatilis)

Penelitian ini bertujuan untuk mengetahui pengaruh dosis ragi roti yang berbeda terhadap kepadatan rotifera (Brachionus plicatilis). Penelitian ini dilakukan pada bulan Agustus 2021 di Laboratorium Perikanan Terpadu, Universitas Sulawesi Barat. Rotifera dikultur dengan pemberian pakan alami Nannochloropsis sp.  sebanyak 41 ml dengan penambahan berbagai dosis ragi roti. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu perlakuan A sebagai kontrol yakni penambahan ragi roti dengan dosis 0,0 mg/L, perlakuan B dosis 15,0 mg/L, perlakuan C dosis 30,0 mg/L, dan perlakuan D dosis 45,0 mg/L. Parameter yang diujikan yaitu kepadatan rotifera. Analisis data menggunakan ANOVA dengan tingkat kepercayaan 95%. Hasil uji ANOVA menunjukkan bahwa pemberian pakan ragi roti dengan dosis yang berbeda memberikan pengaruh nyata (P<0,05) terhadap kepadatan rotifera pada hari ke-3 sampai hari ke-5 pemeliharaan. Kepadatan rotifera tertinggi diperoleh pada perlakuan B yakni pemeliharaan hari ke-4 dengan pakan ragi roti sebanyak 15,0 mg/L yaitu 3.999.333 ind/L, kemudian di ikuti perlakuan A (kontrol) yakni 2.999.667 ind/L, perlakuan C yakni 2.583.000 ind/L dan terendah pada perlakuan D yaitu 2.249.667 ind/L. A B S T R A C T The present study aimed to determine the effect of different doses of baker's yeast on the density of rotifers (Brachionus plicatilis). This study was conducted in August 2021 at the Integrated Fisheries Laboratory, West Sulawesi University. Rotifers were cultured with natural feed Nannochloropsis sp. with a density of 41 ml with the addition of various doses of baker's yeast. Completely Randomized Design (CRD) with 4 treatments and 3 replications, treatment was used for experimental design with the addition of baker's yeast at a dose of 0.0 mg/L, treatment B with 15.0 mg/L dose, treatment C at a dose of 30.0 mg. /L, and treatment D with 45.0 mg/L doses. The parameter tested is the density of rotifers. Data analysis used ANOVA with a 95% confidence level. The results of the ANOVA test showed that the feeding of baker's yeast with different doses had a significant effect (P<0.05) on the maintenance of the density of rotifers on the 3rd to 5th day. The highest density of rotifers was obtained in treatment B, rotifers maintenance on the 4th day with 15.0 mg/L yeast feed, which was 3,999,333 ind/L, then followed by treatment A (control) which was 2,999,667 ind/L), treatment C namely 2,583,000 ind/L and the lowest in treatment D was 2,249,667 ind/L. &nbsp
