Abstract

Salah satu masalah dalam pembelajaran kurangnya variasi dalam kegiatan belajar mengajar yang disebabkan oleh kurangnya pengembangan media ajar, sekolah hanya menggunakan media cetak berupa modul atau buku saja, sehingga siswa kurang aktif dan termotivasi dalam proses pembelajaran bahkan siswa tidak memiliki semangat belajar dalam kegiatan pembelajaran biologi. Telah dilakukan penelitian pengembangan yang bertujuan untuk mengembangkan dan menghasilkan serta mengetahui kelayakan multimedia pembelajaran biologi berbasis Problem Based Learning (PBL) di SMA Negeri 1 Kauditan. Jenis penelitian ini adalah penelitian pengembangan dengan menggunakan model ADDIE: Analysis, Design, Development, Implementation dan Evaluation. Instrumen tes pada penelitian ini adalah wawancara, angket dan dokumentasi. Lembar angket penilaian diberikan kepada subjek penelitian yaitu validator ahli media, validator ahli materi, guru mata pelajaran biologi dan 20 siswa kelas XI MIA 3 SMA Negeri 1 Kauditan. Hasil penelitian dari ahli media diperoleh 90,05% mencapai kriteria sangat valid, penilaian dan ahli materi diperoleh 88,83% mencapai kriteria sangat valid penilaian dan guru mata pelajaran biologi diperoleh 96.66% mencapai kriteria sangat valid dan penilaian respon peserta didik diperoleh 94,4% mencapai kriteria sangat baik. Kesimpulan dari penelitian ini adalah multimedia pembelajaran biologi berbasis PBL di SMA Negeri 1 Kaudian layak digunakan sebagai media pembelajaran.

Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar pada peserta didik di kelas x asisten keperawatan dengan Implementasi Mind Mapping sebagai model yang digunakan pada materi sistem indera manusia. Jenis penelitian ini adalah PTK (Penelitian Tindakan Kelas) dengan dua siklus. Adapun subjek dalam penelitian ini ialah seluruh peserta didik di kelas x asisten keperawatan yang berjumlah 30 orang. Dalam penelitian ini, untuk mengukur hasil belajar para peserta didik digunakan alat evaluasi yakni tes yang berbentuk 10 nomor pilihan ganda dan 5 nomor essay pada materi sistem indera manusia. Pada siklus I menunjukkan nilai rata-rata dari hasil belajar sebesar 63,00 dengan persentase klasikalnya 30% dan dalam penilaian mind mapping menunjukkan 17 peserta didik belum mengerti dalam pembuatan mind mapping. Dikarenakan belum mencapai ketuntasan klasikal pada siklus I maka berlanjut ke siklus II dengan rata-rata hasil belajarnya sebesar 82,50 disertai persentase klasikalnya 90% dan dalam penilaian mind mapping menunjukkan 30 peserta didik sudah mengerti dalam pembuatan mind mapping. Oleh karena itu penelitian ini dikatakan berhasil karena telah mencapai lebih dari 80% persentase klasikalnya, sehingga dapat disimpulkan Implementasi Mind Mapping dapat meningkatkan hasil belajar peserta didik dalam proses pembelajaran pada mata pelajaran Biologi khususnya materi Sistem Indera Manusia pada peserta didik kelas X Asisten Keperawatan di SMK Negeri 1 Bolaang.

Abstract

The research problem in this study is the examination of the correlation between parental perceptions of sex education in early childhood in North Nunu Village, Rainis District, Talaud Islands Regency. The objective of this study is to establish the relationship between parental perspectives on sex education for young children in North Nunu Village, Rainis District, Talaud Islands Regency. A study was conducted in September to determine parents' attitudes of sex education in early childhood. The study employed a descriptive survey research method, utilising a quantitative methodology. According to the percentage calculations from the distributed questionnaire, it is evident that a significant number of parents expressed agreement rather than providing alternative answers when asked about their understanding of sex education for early childhood. Under the category of disagreement. The computation of the proportion for each indicator item has yielded a cumulative value of 1447, with an average of 72.35% indicating their agreement to receive instruction during early life. The correlation data computations indicate a positive association between parents' impressions of sex education in early infancy. Specifically, the resulting correlation coefficient (rxy) is 0.1000, based on data from 20 respondents. The significance level for this relationship is 0.05, and the critical value (rtable) is 0.422. These computations indicate that the value of rcount is greater than the value of rtable, with a significance level of 0.05. If the count of r is more than the count of rtable, then the hypothesis test concludes that there is a correlation between parents' judgements of sex education in early infancy.

Abstract

Kolongan Village is one of the villages in Talawaan district of North Minahasa, North Sulawesi. In the village of Kolongan, some springs are potentially a clean water source for the people of the village. This research aims to analyze the quality of the springs in the village of Kolongan Talawaan, Prefectures as a water source. This type of research is quantitative, and the method used in this research is the Indonesian National Standard (SNI) according to the water quality parameters that have been established with the direct observation plan of the physical properties of water and with the laboratory testing plan for the observation of water chemical and biological properties with indicators of iron, sensitivity, manganese, E.coli, taste, and smell. The research was conducted from July 24, 2021, to September 20, 2021. The water quality measurement results in the spring in one village of Kolongan showed iron <0.0086 mg/L, iron 69-93 mg/ L, manganese 0.03-0.07 mg / L, E. coli, 11 CFU, not sensitive and odorless. Water source 2 showed iron <0.086 mg / l, density 75-85 mg/ l, manganese 0.02-0.03 mg/l, and E. coli, 3.6-9.2 CFU, is not sensible and odorless. The pollution index calculation indicates that the springs in Kolongan Village belong well. However, because they still contain biological reservoirs, it is necessary to have an advanced process for them to be consumed by the community.

Abstract

The lack of scientific information about the current condition of the mangrove ecosystem on the Molas beach in the Bunaken District of Manado City is an important reason to conduct a study related to the analysis of mangrove forest vegetation. The purpose of this research is to identify the types of mangroves and to find the Important Value Index (INP) of mangroves on the Molas beach in the Bunaken District of Manado City. Data collection was conducted using the line transect method with plots at only one observation station, which was then analyzed to determine the Importance Value Index (INP). Based on the observations, it was found that four types of mangroves were present at the research location. The dominant mangrove species are Bruguiera Cylindrica, Bruguiera gymnorrhiza, Aegiceras cosniculatum, and Ceriops tagal. The substrate condition, which is dominated by muddy sand, and the water quality parameters that affect mangrove growth generally still meet the standards for mangrove growth. The species Ceriops tagal has the highest values of Relative Density, Relative Frequency, and Relative Dominance, resulting in the highest INP. Meanwhile, the lowest INP was found in the species Bruguiera gymnorrhiza in the tree category
