Abstract

Penelitian ini bertujuan untuk membandingkan pemahaman materi barisan dan deret antara siswa SMK Negeri dan SMK Swasta. Metode penelitian yang digunakan adalah penelitian deskriptif komparatif dengan pendekatan kuantitatif. Data diperoleh melalui penyebaran kuesioner berupa soal pilihan ganda kepada siswa SMK Negeri dan SMK Swasta menggunakan Google Form. Uji prasyarat dilakukan untuk menguji normalitas dan homogenitas data. Hasil analisis menunjukkan bahwa kedua kelompok siswa memiliki pemahaman yang terdistribusi normal dan homogen. Selanjutnya, dilakukan uji komparasi menggunakan uji-t untuk membandingkan pemahaman antara kedua kelompok siswa. Hasil uji menunjukkan adanya perbedaan yang signifikan dalam pemahaman materi barisan dan deret antara siswa SMK Negeri dan SMK Swasta. Kesimpulannya, siswa SMK Negeri memiliki pemahaman yang lebih baik dibandingkan siswa SMK Swasta dalam materi barisan dan deret. Penelitian ini memberikan kontribusi dalam memahami perbedaan pemahaman matematika antara siswa dari kedua jenis sekolah tersebut.

Abstract

Wild betta fish Betta channoides is an endemic species from East Kalimantan, Indonesia. Currently, wild betta Betta channoides is classified as a species threatened with extinction due to a declining population, caused by environmental damage to its natural habitat. This damage is driven by the construction of the new capital city in East Kalimantan, deforestation for oil palm plantations, and overfishing to meet trade demands. To preserve the existence of Betta channoides, domestication efforts are necessary. Depok Ornamental Fish Cultivation Research Institute has been working on cultivating this species since 2019. However, one of the current challenges is the suboptimal growth of larvae due to the lack of knowledge of suitable life feeds for accelerating fish growth. The aim of this study is to enhance the growth of wild betta fish Betta channoides larvae by providing different types of life feeds. The method used was a completely randomized design (CRD) with four treatments and three replicates: Artemia sp. (K), bloodworms (CD), silk worms (CS), and water fleas (KA). Data were analyzed using SPSS with Duncan's test and the Kruskal-Wallis test. The results showed that feeding with silk worms yielded the optimum outcomes for absolute length growth 0.780 ± 0.020 cm, absolute weight growth 0.272 ± 0.005 g, and survival rate 93.33 ± 5.773%. The data indicated that silk worm treatment had a significant effect compared to the control, bloodworms, and water fleas. The study concluded that different feeds significantly affect growth performance and survival rates, with silk worms producing the highest results.

Abstract

Several countries have placed groundwater spatial information inventories in a significant position in groundwater management. However, this effort has not been found in Indonesia. This is probably due to limited references. This study aims to determine the spatial information of groundwater as a basis for inventory. The research also aims to identify the capabilities of Arc GIS online as a medium for inventorying groundwater spatial information. As a preliminary study, Sitimulyo Village, Bantul Regency, Special Province of Yogyakarta was used as the study area. Data was collected through field surveys. Spatial interpolation was used for data analysis. Based on the results of the study, it is known that the free groundwater in the majority of the research area is 6.7 to 9.5 meters deep. Studies on electrical conductivity, temperature, and alkalinity also indicate that groundwater quality is good. Arc GIS online can be used as a medium for inventorying groundwater information. Easy accessibility, supported by simple data management and updating, is the advantage of Arc GIS online.
