Distribution of Gastropoda and Its Relation with Environmental Characteristics in Coastal Waters of Nusalaut Island, Central Maluku

Nusalaut Island is one of the small islands in Maluku waters that is influenced by the dynamics of Banda Sea. The aim of this study was to investigate the density and spatial distribution of gastropods and its relation with environmental characteristics using multivariate analysis i.e., Principal Component Analysis (PCA) and Correspondence Analysis (CA). This study was conducted in Nusalaut Island as a part of Marine Resources Inventory Programme in Nusalaut Island in 2009. Fieldwork was conducted in northern Nusalaut Island using systematic random sampling method. Results showed that the highest density was Nassariidae family and other low density were from the familes of Cerithiidae, Buccinidae, Terebridae, and Conidae, respectively. The environmental characteristics affected species composition and density of gastropods. Distribution of environmental characteristics and spatial distribution of gastropods at each station was influenced by a combination of several parameters. Microhabitat pattern, predatory, and human activities also affected the distribution of gastropods

Analisis Perubahan Meander Saluran Tanah Akibat Variasi Debit (Uji Model Laboratorium)

Sungai merupakan saluran yang terbentuk secara alamiah, salah satu bentuk sungai yang menarik untuk dikaji adalah sungai yang mempunyai meander. Aliran pada bagian meander sungai tidak sama dengan aliran pada bagian lurus sungai. Aliran yang berbeda pada meander sungai akan menimbulkan gerusan dan endapan sehinggan terjadi Perubahan geometri pada bagian meander sungai. Tujuan penelitian ini adalah untuk menganalisis Perubahan jari-jari meander saluran tanah yang diakibatkan oleh variasi debit. Untuk melihat Perubahan yang terjadi pada jari-jari kelengkungan sungai, dibuat sebuah model hidraulik dengan saluran berbentuk trapesium, sudut tikungan 900 dan radius of curvature Rc=279 cm. Dinding tebing dan dasar saluran dibentuk dengan tanah bergradasi buruk. Dalam pengamatan ini, saluran dibagi menjadi 13 potongan melintang. Pengamatan dilakukan dengan menentukan 3 variasi debit, yaitu Q1 = 38,16 L/menit; Q2 = 49,65 L/menit dan Q3 = 63,01 L/menit. Perubahan paling besar terjadi akibat aliran Q3 = 63,01 L/menit sebesar 1,005 kali dari nilai jari-jari awal. Hasil penelitian menunjukkan waktu dan Perubahan jari-jari mempunyai hubungan yang erat, namun Perubahan jari-jari yang terjadi sangat kecil pada meander saluran tanah

Pelatihan dan Pendampingan Pembuatan Media Pembelajaran “Tabung Resonansi” Untuk Guru Fisika di SMK Al Amin Kilang

This training and mentoring activity aims to increase the knowledge of teachers in making physical learning media, especially sound wave material at SMK Al Amin Kilang. The learning media created from this training is a resonance tube. Tools and materials used are statif of wood, used bottles, paralon pipes, speakers, trafo, amplifiers, water hoses and thermometers. To generate sound waves on resonance tubes used simulation applications from PhET. Based on the results of resonance tube training activities made can show resonance symptoms. The quick value of the resulting sound wave propagate is 347,225 ± 2.95 m/s at a temperature of 250C and 353.375 ± 4.18 m/s at a temperature of 310C. This can prove that the higher the air temperature, the faster the sound waves that propagate in the air. The coefficient of deviation of this resonance tube is not up to 2 %, which is 0.85 % for the temperature of 250C and 1.182 % for the temperature of 310C. Thus, these resonance tubes can be used in standing wave experiments
