Abstract

ABSTRACT The waters of sibolga is the waters are very widespread in , this area is densely populated, so there are many community activities that take place such as Transportation, Fisheries, Bathing, sand Mining and other.The purpose of this study is to determine the role of macrozoobenthos as a bioindicator of water quality in the waters of Sibolga Tapanuli Tengah, as well as determine the quality of water in the flow of the waters Sibolga physical properties, chemical has. The research was conducted from November 2019 to February 2019, the samples taken from the three research stations. From the results obtained Macrozoobenthos in the identification in this study consisted of 3 Phyla of invertebrates namely : Annelids, which consists of 2 classes, Arthropods consisting of 1 class and Molusca, which consists of 1 class. Based on the data of macrozoobenthos obtained at each research station, then the obtained value of population density, relative density and frequency of presence of that at station I the value of its highest density is Tubifex sp. with the value of the density of the population of 18,519 individual/m2, the density is relatively 25,862% and the frequency of the presence of 55,555%. off at 3. at station 2 the highest density is Tubifex sp. with the value of the density of the population of 18,519 individuals/m2, relative density 25,862% and a frequency of 55,555%. also note that the total score obtained by the method storet, namely -30, this shows that if connected with the raw water quality of class I is then classified in the waters of class III, which means that light polluted. The high total score method storet on the entire research station due to the presence of a variety of activities at each of the stations, settlements, sand mining and other activities. Where these activities produce waste, which in the end increases the content of Phosfat, COD, TSS and BOD5, thus causing the waters of the Waters of Sibolga is light polluted.

Abstract

Research has been conducted on using hyacinth biogas (Eichornia crossipes) and goat dung (faeces) as alternative energy sources. This research aims to design reactors, measure temperature, measure pH, conduct flame tests. This study shows that the temperature, pH, and composition of material comparison greatly influence the formation of biogas. The ratio of hyacinth mass and water used is 1.1, 1:2, and 1:3 with each ratio given goat dung as much as 400 grams. All treatments produce a gas that can ignite. Heat produced is between 12.75 calories to 16.6 calories.

Abstract

Penelitian ini adalah penelitian deskriptif kualitatif yang bertujuan untuk mendeskripsikan pelaksanaan pembelajaran Proyek Penguatan Profil Pelajar Pancasila (P5) dalam mengembangkan kreativitas siswa serta mengidentifikasi hambatan yang dihadapi selama proses tersebut. Subjek penelitian adalah guru kelas IV dan enam siswa SD Negeri 7 Salotungo Kabupaten Soppeng. Data dikumpulkan melalui wawancara semi-terstruktur dan observasi non-partisipan, kemudian dianalisis dengan model Miles dan Huberman melalui reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa pembelajaran P5 dengan tema Gaya Hidup Berkelanjutan berkontribusi pada kreativitas siswa. Kreativitas tampak pada kelancaran menuangkan gagasan, orisinalitas ide unik, serta elaborasi dalam menyempurnakan karya dari barang bekas. Siswa mampu menghasilkan ide, menyampaikan pendapat, dan menyusun karya sederhana. Hambatan yang muncul meliputi keterbatasan waktu, minimnya pelatihan guru, serta rendahnya kepercayaan diri siswa. Disimpulkan bahwa P5 mampu mendorong tumbuhnya kreativitas meski memerlukan dukungan lebih lanjut.
