Abstrak: Forest and land fires in the province of Riau caused land use activIties by ~panies and farmers. Factors is causing forest fires and land on farmers is the ~it of burning on the land preparation; the community does not feel the direct itpact of forest and land fires, and the assumption that burning the land can ~rtilize the soil. Whereas the factors causing forest and land fires on the company i not applied to the policies and rules prohibiting burning by these companies. In ~dition to the factors that have not been optimal coordination between working ® its of local government and the institutions of the central government ~thorities to conduct surveillance as well as a program for tackling forest fires ~d land which is not effective causing forest and land fires continue to occur in i.e Riau Province. t-he property rights of natural resources (farmers and plantation companies and fi;>restry company) is not one of the root problems cause forest and land fires in the lfiau Province. On the other hand the existence of externalities are internalized i ctors is difficult, as the smoke became one of the root problems cause forest and i nd fires. The root of the problem is the weakness of the institutional response to fOrest and land fires, as well as yet of any policy or regulations at the national mvel, provincial and district, which makes the user able to manage natural (0 m... sources . rmplementation of incentives need to be done to improve the management forest and land fires in Riau Province. For companies, the guarantee mechanism rewards the performance of environmental management or other economic incentives such as tax reductions carried out by government agencies which have strong legitimacy. While for the society, the award can be a form of venture capital for the management of its land, or technical assistance in operational management of activities here. The sanction given is assertiveness the Government to punish violations by the company or society that burns the land through the lifting of the freeze or permit the company and social sanctions for the community rife importance of research to get the giving of incentives or disincentives Cfchnique based on social and cultural conditions of local communities, especially (f!1 the Riau Province.

Judul: Analisis Emisi CO2 dari  Kebakaran Hutan Menggunakan Nilai Fire Radiative Power (FRP) (Studi Kasus:  Provinsi Riau).
Abstrak: Salah satu daerah di Indonesia yang rawan terjadinya kebakaran hutan dan lahan adalah Provinsi Riau. Kebakaran hutan dan lahan di Provinsi Riau terjadi pada berbagai tutupan lahan dan jenis tanah yaitu tanah gambut dan mineral. Kebakaran hutan menghasilkan gas rumah kaca, salah satunya adalah karbon dioksida. Penelitian ini dilakukan untuk mengestimasi emisi karbon dioksida yang dihasilkan dalam kebakaran hutan. Penentuan emisi karbon dioksida dari kebakaran hutan yang terjadi pada tahun 2016-2018, digunakan data Fire Radiative Power (FRP) serta menggunakan metode buffer untuk menduga luas kebakaran dari berbagai tutupan lahan. Data FRP yang digunakan adalah data dengan tingkat kepercayaan lebih dari atau sama dengan 70% sehingga dapat dikatakan data tersebut adalah titik api. Hasil perhitungan data menggunakan aplikasi ArcGIS, menunjukkan bahwa kebakaran hutan pada tahun 2016, 2017, dan 2018 terdeteksi 1.432, 121, dan 1.238 titik FRP. Luas area terbakar yang terduga dari hasil perhitungan tahun 2016, 2017, 2018 sebesar 95.396 ha, 6.911 ha, dan 46.545 ha. Untuk emisi CO2, pada tahun 2016 emisi karbon dioksida sebesar 313.456 ton, pada tahun 2017 menghasilkan emisi karbon dioksida sebesar 34.936 ton, dan pada tahun 2018 menghasilkan 155.461 ton emisi karbon dioksida., One of the areas in Indonesia that is prone to forest and land fires is Riau Province. Forest and land fires in Riau Province occur in various land covers and soil types, namely peat and non-peat soils. Forest fires produce greenhouse gases, one of which is carbon dioxide. This study was conducted to estimate the carbon dioxide emissions produced by forest fires. The determination of carbon dioxide emissions from forest fires that occurred in 2016–2018 used fire radiant power (FRP) data and the buffer method to estimate the area of fire from various land covers. The FRP data used is data with a confidence level of greater than or equal to 70%, so it can be said that the data is hotspots. The results of data calculations using the ArcGIS application show that 1,432, 121, and 1,238 FRP points were detected in forest fires in 2016, 2017, and 2018. The estimated burned area from the results of calculations in 2016, 2017, and 2018 was 95,396 ha, 6,911 ha, and 46,545 ha. For CO2 emissions, in 2016 carbon dioxide emissions were 313,456 tons. In 2017 they produced 34,936 tons of carbon dioxide emissions, and in 2018 produced 155,461 tons of carbon dioxide emissions.

Judul: Gambaran Histologis Ovarium Kucing Domestik (Felis catus) yang Disimpan pada Suhu 4 °C Selama Tujuh Hari
Abstrak: Penelitian ini bertujuan mengetahui pengaruh penyimpanan ovarium selama tujuh hari pada suhu 4 °C terhadap gambaran histologis sel-sel folikel kucing domestik. Penelitian ini menggunakan 14 sampel ovarium kucing domestik dengan 7 kelompok perlakuan berbeda. Pengamatan mikroskopis dilakukan dengan membuat preparat histologi dan diwarnai dengan pewarnaan hematoksilin eosin untuk mempelajari morfologi sel folikel ovarium. Gambaran kelompok perlakuan hari pertama dan hari kedua menunjukkan kondisi yang paling baik: sel-sel granulosa pada folikel preantral dalam keadaan intak, tidak ditemukan oosit yang nukleusnya mengalami piknosis, sitoplasma homogen eosinofilik, sel-sel interstisial melekat pada stroma ovarium, folikel primordial tampak memiliki warna dan ukuran yang seragam. Hari ketiga dan keempat penyimpanan memperlihatkan sel-sel granulosa yang tidak melekat dengan baik pada membran basal dan berbentuk tidak beraturan. Hal serupa juga terjadi pada hari kelima, keenam, dan ketujuh dengan semakin menurunnya densitas warna sel-sel folikel preantral beserta inti selnya. Penyimpanan ovarium kucing pada suhu 4 °C sebaiknya tidak lebih dari dua hari (48 jam) setelah ovariektomi, sehingga penghambatan metabolisme sel dan kondisi normal oosit yang diharapkan sebelum dilakukan fertilisasi maupun maturasi in vitro dapat dipertahankan.
