Abstract

We conducted an initial survey of the microalgal diversity of Kati River located in the City of Lubuklinggau, South Sumatra Province, on March to May 2017. This study aimed to determine the microalgal diversity of Kati River as a baseline data. This study found 47 microalgal species belonging to 42 genera and 27 orders. We found the member of Chlorophyceae and Bacillariophyceae were the most abundant microalgae. We also compared the diversity of Kati River to two other rivers in Lubuklinggai, Mesat River, and Kalingi River. The microalgal diversity of Kati River is higher than Mesat River but lower if compared to Kalingi River. The physicochemical factors of Kati River waters were also measured, the average water temperature was 27°C, average pH was 6.7, and average water transparency was 57 cm. This study found that those environmental factors influenced microalgal diversity in Lubuklinggau rivers, Kati River, as well as Mesat River and Kalingi Rivers, have indicated the same results.

Abstract

Many students have not yet completed the science learning process, so there is no need for students to take part in the improvement program to meet the Minimum completion criteria. The purpose of this study was to analyze the science learning outcomes of VIII-grade students of Air Setan Middle School through the Problem Based Learning model. The design of this study used a design that was created pretest-posttest Group Design. Samples are taken at random (simple random sampling). Data collection techniques using essay questions, this test is done twice, namely before (pre-test) and followed (post-test) learning process. Data analysis techniques using the t-test, in using this t-test, both the experimental class and the control class data must be normal and have a homogeneous variant that is tested for normality and homogeneity before testing the hypothesis with the t-test. Learning outcomes using problem-based learning are better because this learning involves students solving problems, by means of their creative ideas and ideas, so students do not easily forget the lessons they have learned

Abstract

ABSTRACTThis activity was motivated by income problem in community of Taba Remanik Village which is based on the agricultural sector where prices fluctuate. So that the family economy becomes weak. The partner regions are regions that have another commodity than rubber, namely: kabau. The kabau utilization in the partner regions has not been optimized. Therefore, partners especially PKK mothers, need to be equipped with the knowledge to utilize kabau so that it has high economic value. One of the method that can be used is to process the kabau into processed crackers. This service activity consists of 4 steps, namely: observation, delivery of material, practice of making crackers and monitoring evaluation. The material presented at the service activities are: Introduction of kabau, the nutritional content of kabau, the benefits of kabau and the practice of making kabau crackers. The community service activities in Taba Remanik Village went well and the community was very enthusiastic. The result of community service activities is that the community is able to practice how to make kabau crackers properly. Keywords: Taba Remanik, Kabau, Crackers ABSTRAKKegiatan ini dilatarbelakangi oleh masalah penghasilan pada masyarakat Desa Taba Remanik yang bertumpu pada sektor pertanian dimana harga fluktuatif. Sehingga perekonomian keluarga menjadi lemah. Daerah mitra merupakan daerah yang memiliki komoditas sampingan selain karet, yaitu: kabau. Pemanfaatan buah kabau di daerah mitra belum optimal. Oleh karena itu, mitra terutama ibu-ibu PKK perlu dibekali pengetahuan untuk memanfaatkan buah kabau agar bernilai ekonomis tinggi.  Salah satu cara yang dapat digunakan yaitu mengolah buah kabau menjadi olahan kerupuk. Kegiatan pengabdian ini terdiri dari 4 tahapan, yaitu: observasi, penyampaian materi, praktek pembuatan kerupuk dan monitoring evaluasi. Materi yang disampaikan pada kegiatan pengabdian tersebut yaitu: Pengenalan buah kabau, kandungan gizi buah kabau, manfaat buah kabau dan praktek pembuatan kerupuk buah kabau. Kegiatan pengabdian yang dilakukan di Desa Taba Remanik berjalan dengan baik dan masyarakat sangat antusias. Hasil kegiatan pengabdian kepada masyarakat ini adalah masyarakat mampu mempraktekkan cara membuat kerupuk buah kabau dengan baik. Kata Kunci: Taba Remanik, Kabau, Kerupuk
