Abstract

Membiasakan hidup belajar yang nyaman dan menyenangkan dalam proses timbal balik antara guru dan siswa dalam proses belajar mengajar dibutuhkan strategi dan model pembelajaran yang efektif yakni model pembelajaran kooperatif tipe Team Assisted Individualization ini akan terjadi interaksi yang aktif antara siswa dan siswa, serta siswa dengan guru sebagai pembimbing. Model pembelajaran Team Assisted Individualization ini juga merupakan tehnik untuk mengatasi kesulitan belajar siswa secara individu dalam suatu kelompok. Tujuan Penelitian adalah agar dapat mengetahui hasil belajar siswa memelaui penerapan model pembelajaran kooperatif tipe Team Assisted Individualization pada materi dinamika kependudukan dan pembangunan nasional di SMP Negeri 5 Kota Ternate. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang mengikuti taha-tahap penelitian sebagai berikut: (1) perencanan tindakan (planning), (2) penerapan tindakan (action), (3) observasi (observation) (4) refleksi (reflecting). Hasil penelitian ini menunjukan model pembelajaran Team Assisted Individualizatio, berhasil meningkatkan hasil belajar siswa serta penguasan materi mengenai Dinamika Kependudukan dan Pembangunan Nasional. Hal ini ditunjukan dengan meningkatnya aktivitas siswa, siswa memiliki keberanian bertanya, menjawab pertanyaan, berdiskusi dan bekerjasama dengan sesama anggota kelompok. hasil observasi aktivitas guru pada siklus I skor yang diperoleh 64,4% pada siklus II mengalami peningkatan hasil observasi aktivitas guru pada siklus II skor yang diperoleh 87%. Hasil belajar siswa juga mengalami peningkatan pada penguasaan materi dinamika kependudukan dan pembangunan nasional yang dapat dilihat dari perolehan nilai siswa, yakni terdapat 18 siswa (81,8%) yang belum mencapai KKM dan hanya terdapat 4 siswa (18,2%) yang mencapai KKM pada siklus I. Pada siklus II mengalami peningkatan yaitu terdapat 13 siswa (59%) sehingga jumlah ketuntasan siswa secara klasikal menjadi 17 siswa (77,3%) dan hanya 5 siswa (22,7%) yang belum mencapai KKM. Pembelajaran dengan Team Assisted Indivudalization dapat menciptakan suasana pembelajaran kreatif, aktif dan menyenangkan.

Abstract

This study aims to analyze the osmotic work level and pattern of osmoregulation at mollusc Teredo navalis Linnaeus 1758 in mangrove root habitats from different salinities. Case study was performed with the purposive sampling method. The research data were analyzed descriptively and quantitatively. The sampling technique is based on tidal conditions of seawater. Two locations was designated, namely station I and II in the north and the south respectively. Teredo navalis samples were taken from 2 types of mangrove roots. Analysis of the level of osmotic work using Automatic Micro Osmometer Roebling Type 13/13 DR. Salinity was measured using a refractometer. The results showed that the osmotic level of Teredo navalis in the root habitat of Rhizophora sp. and Avicennia sp. at high and low tide conditions varied, specifically 523 mOsm/l H2O, 123 mOsm/l H2O, and 32 mOsm/l H2O. This varying level of osmotic action results in three patterns of osmoregulation, viz. hyperosmotic, hypoosmotic, and isosmotic. The highest salinity was found in Avicennia sp. mangrove at station II and the lowest in Rhizophora sp. at low tide at station II, with the value was 31‰ and 10‰ respectively. Differences in salinity determine the osmoregulation pattern of Teredo navalis L in different habitats.

Abstract

T. navalis has high reproducibility and is widely distributed according to physiological tolerance and conditional factors. The purpose of this study was to analyze the growth and condition factors of Teredo navalis Linnaeus 1758 in the mangrove root habitat of Avicennia sp. This type of research is a case study, using the purposive sampling method. Data collection was carried out at two research stations, starting with determining the roots and stems of Avicennia sp mangroves in 70 cm pieces, then observing growth and taking samples. The results showed that the growth of T. navalis in the root habitat of Avicennia sp at treatment S1 (7‰) was 9.96±0.06 gr and the highest at treatment S3 (21‰) was 18.20±0.02 gr. salinity and absolute weight growth of T. navalis with a quadratic pattern with the equation Y = 0.1524x+11.345 R2 = 0.1506, and the optimum point of salinity of 14‰ media can produce maximum absolute weight growth of T.navalis (Y) = 15.33 gr. The results of the calculation of the value of the condition factor (FK) on the relationship between length and weight of T. navalis in the root habitat of Avicennia sp W = 26.29 + 0.39x. Based on the graph of the relationship between length and weight, the value of Y = 00338x2 + 1.8421 + 57,115 and R2 = 0.5834.
