The writing of scientific writing is one of the efforts to develop the profession of teachers of SMA N 2 Tambang in Kampar regency. This training aims to equip teachers in terms of strategies to develop scientific papers properly in accordance with the guidelines of writing, and equip teachers in the publication procedures of scientific papers in the journal. The training of scientific writing is done by varied lecture method and practice. The lecture method is needed to explain the procedure for the preparation of scientific papers, including how to arrange classroom action research into a scientific paper. Methods of practice are needed to allow the participants to write scientific papers in the form of articles for journals. The training activities of the writing of scientific papers as a whole can be said to be well seen from the achievement of the target of the trainee, the achievement of the training objectives, the achievement of the planned material targets, and the ability of the participants in the mastery of the material. The supporting factors for the implementation of Community Service activities are the availability of experts in SMA N 2 Tambang, the enthusiasm of the participants, the support of the principal of the place of administration, and the supporting funds of the faculty.
Berbagai macam bentuk usaha untuk mencukupi perekonomian keluarga telah dilakukanmasyarakat khususnya Desa Kartama. Upaya yang mereka tekuni tentunya harus dapatmenghasilkan peningkatan ekonomi keluarga. Pertanian sayur mayur, ubi kayu danpeternakan merupakan salah satu usaha yang dilakukan oleh sebagian besar masyarakatDesa Kartama hingga saat ini.Usaha ini tentu sangat menguntungkan jika bisa dikeloladengan baik. Namun, terdapat permasalahan yang timbul dalam usaha pertanian sayur,perkebunan dan peternakan bagi sebagian masyarakat Desa Kartama. Permasalahanyang terjadi saat ini yaitu mahalnya harga pupuk komersil (kimia) yang dibutuhkanuntuk sektor pertanian serta limbah peternakan baik urin maupun feses ternak yangdapat mencemari lingkungan. Untuk itu melalui program pengabdian kepada masyarakatini kami memberikan ide kepada warga setempat yang memiliki perkebunan seperti sayurmayur, umbi-umbian untuk membuat pupuk sendiri dari bahan organik agar dapatmengurangi biaya perkebunan warga, dikarenakan untuk membuat pupuk organik cairtersebut tidak memakan banyak biaya karena bahan dasarnya diperoleh dari limbahrumah tangga seperti sisa buah-buahan dan sayur-sayuran. Disamping itu limbah daripeternakan juga dapat dimanfaatkan sebagai bahan dalam pembuatan pupuk organikcair.
Scientific writing training was one of the efforts to develop the profession of high school teachers N 7 Pekanbaru. The training aims to equip high school teachers of N 7 Pekanbaru in terms of strategizing the scientific papers correctly according to the writing guidelines, and equip the teachers in the scientific writing publication procedures in the journal. The training method is the percentage of resources, discussion and simulation of papers that have been prepared by the trainees. The lecture method is necessary to explain the procedures of scientific writing, including how to arrange class action research into a scientific work. The exercise/practice method is required to give participants a scientific writing for the journal article. This scientific writing training activity in its entirety can be said to be seen from the achievement of the target participants, the achievement of training objectives, the achievement of planned target material, and the ability of participants in Material. The supporting factors in this community service activities are the availability of experts who are imported to the training in SMA N 7 Pekanbaru, participant enthusiasm, the support of the school principal, and the supporting fund of the university . The Output of this activity is expected to have several teacher papers (participants) in the form of journals and proceeding that are ready to be submitted to the relevant journal.

This research aims to utilize blood cockle shell waste and silica sand as a new innovation in the manufacture of calcium silicate minerals which were used as fillers in paper making industry. In this study the manufacture of calcium silicate mineral fillers (CaSiO3) used solid state reaction technique at a temperature of 1000 o C. Some researchers have tested the use of blood cockle shells as the raw materials for making calcium silicate, so further research was needed to find out whether the calcium silicate produced can be used in paper making. Sample characterization was carried out with Fourier Transform Infrared (FTIR), Keyence microscopy and X-Ray Diffraction (XRD). The results showed that the calcium silicate phase contained the wollastonite-1A phase (CaSiO3) with the highest intensity peak at an angle of 2θ = 26.8225. FTIR analysis also showed the structure of calcium silicate with the formation of Si-O-Si and O-Si-O functional groups at a wavelength of 460 cm-1 , Si-O-Ca at a wavelength of 962 cm-1 and O-Si-O cm-1 at a wavelength of 901 cm-1. The microstructure analysis using Keyence microscope showed that the sample granules were globular in shape with a particle size of approximately 14 µm. From all the paper testing results consist of brightness, bulk density, tearing, bursting, tensile and folding endurance showed that calcium silicate filler has fulfill the TAPPI International standard.
Petroleum waste (crude oil) has become one of the sources of pollution in the sea. The pollution caused comes from several factors, oil spills from tankers, deliberate disposal of irresponsible industries. The layer of crude oil on the surface of the air holds back gas exchange from the atmosphere and reduces the solubility of oxygen in the waters so that it interferes with the respiration and photosynthesis processes in phytoplankton which are food producers in the sea. This study aims to characterize the synthesized TiO2 photocatalyst material using two methods, namely Sol-Gel (SG) and Hydrothermal (HD) which will then be used for applications in petroleum waste. To determine effectiveness of TiO2 photocatalyst in reducing crude oil spills on the sea surface based on fatty oil parameter tests. The synthesis of TiO2 was carried out by the solgel method (SG) and the hydrothermal method (HD) at various temperatures of 300 oC, 500 oC, and 700 oC. Characterization of the material formed using the SEM-EDX instrument, showed that in general it is spherical in shape, and is composed of C, O and Ti elements. The maximum effectiveness of SG-300, SG-500, and SG-700 was able to reduce fat oil content by 57.19%, 66.14% and 41.42% while HD-300, HD-500, and HD-700 were able to reduce fatty oil content. maximum of 60.87%. , 56.41% and 45.68% in the 120 minute irradiation time. The results showed that the photodegradation process in petroleum waste treatment using TiO2 material was able to reduce the fat oil content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
