Abstract

Scientific work is a form of scientific publication used by teachers to support the Sustainable Professional Program (PKB) that has been launched by the government to actualize the work of teachers as professional staff. Many teachers do not understand how to make a good and correct scientific work, even though scientific work is a mandatory requirement for teachers for the promotion process. The implementation of community service activities aims to provide workshops on scientific writing techniques for teachers at SMA Negeri 1 Lubuk Dalam. The strategy used is through lecture, tutorial, and discussion methods and observation sheets to see the effectiveness of the methods used. The result of this dedication is that the teacher is able to understand the techniques of writing scientific papers well and correctly so that they are suitable for publication

Abstract

Crab shells are the result of the sea containing calcium and carbonate which combine to form calcium carbonate (CaCO3). The calcium carbonate contained in the crab shells is made into PCC (Precipitation Calcium Carbonate) and CO3Ap (Apatite Carbonate). PCC production in this study used the method of carbonation and carbonate apatite with the dissolution-precipitation reaction. Preparation of apatite carbonate by mixing calcium carbonate derived from crab shells with gypsum and immersing it in a solution of diammonium hydrogen phosphate ((NH4)2HPO4) in the form of blocks with a mass composition of G50P50, G50K50 and G50C50. The resulting Apatite Carbonate Type-B can be proven by the results of FT-IR spectrum analysis. For SEM analysis which showed differences in morphology, distribution and particle size of each block of carbonate apatite.

Abstract

Fly ash is produced in the combustion process of coal in a factory. It can be used in the construction industry, particularly in cement and concrete production. Moreover, fly ash has been added as one of the materials in cement production due to composition similarities between fly ash and other raw materials. However, fly ash is not environmentally friendly as it contains inorganic compounds that are harmful to the environment. Therefore, it is important to know its properties and characterization for further research, advantages and disadvantages that follows. This study was focusing on the Ca, Cu, Mg and Si in fly ash as a byproduct of coal combustion. Based on the results, SiO2 and CaO levels consecutively are 21,17% and 0,65% indicated that fly ash can be added as one of the materials used in cement production. Furthermore, the toxic Cu and Mg in fly ash displayed its safety in the environment, in sequence are 0,02855ppm and 0,81825ppm.

Abstract

Kelapa sawit adalah salah satu komoditas andalan bagi Kabupaten Siak. Desa yang dibentuk berdasarkan sistem Perkebunan Inti Rakyat (PIR) PT. Perkebunan Nusantara V Sei Buatan yang bergerak di bidang industry kelapa sawit di Kabupaten Siak adalah Desa Teluk Merbau. Saat ini perkebunan kelapa sawit di Desa Teluk Merbau sedang melaksanakan proses replanting atau peremajaan, yang pada prosesnya akan menghasilkan limbah. Hingga saat ini tidak semua limbah hasil proses peremajaan telah mengalami pengolahan. Diantara limbah yang dihasilkan dan memiliki potensi untuk diolah adalah nira kelapa sawit. Dengan tahapan proses yang sederhana diharapkan nira kelapa sawit dapat menjadi alternatif bahan baku pembuatan gula merah selain kelapa atau aren. Hal ini akan sangat bermanfaat untuk daerah – daerah yang berada di sekitar perkebunan kelapa sawit dan jauh dari akses transportasi. Diharapkan juga setelah kegiatan pengabdian ini, masyarakat dapat menerapkan pengetahuan dan menambah pendapatan keluarga dengan usaha gula merah berbahan dasar nira kelapa sawit.
