Abstract

Cadmium (Cd) is one of non-essensial metals and toxic in low concentration. Cd polution in freshwater ecosystem from the usage of Cd in many industrial activities can interfere biology system of aquatic animals. Evaluation of heavy metals in freshwater ecosystem can be predicted with accumulation of metals in organism. Mussels are aquatic organism that capable to accumulate metals in their body. The purpose of this research were to study pattern of Cd accumulation in body mussels including mantle, gills, and kidneys. Mussels are exposed to Cd via water (20 µgL-1)for 24 days, followed by 12 days of depuration. On day 0, 1, 6, 12, 18, 24 (exposure time) and day 30, 36 (depuration time), mussels were dissected into mantle, gills, and kidneys. Cd bioaccumulation in all organ was determined by using Atomic Absorbance Spectrophotometer (AAS). The result showed that pattern of Cd bioaccumulation attend to increase in all organs within exposure time and attend to decrease within depuration time. The higest level of accumulation being in kidney, followed by gillsand mantle. Keywords: bioaccumulation, cadmium, freshwater mussel

Abstract

Oxalate is one of the plant metabolites. Oxalate can enter into the formation of both bio-soluble and insoluble oxalate in the some plants. Some plant which containing oxalates has been a good source of certain minerals, vitamins, dietary fiber, and some antioxidant phytochemicals. Most of vegetables are usually consumed both as a raw and or after cooking. On the other hand, oxalate can accumulate in the renal glomeroli and can lead to the formation of kidney stones and renal disorders. Besides that, the size, location, accumulation and formation oxalate acid to be calcium oxalate crystals in some vegetables may be affected by physical, chemical, and biological condition such us temperature, light exposure, pressure, time harvesting, pH, ion concentration, and macro and or micro ratio of field. This paper was aimed to describe: (1) distribution and formation of oxalate in some part of plants, (2) some methods how to reduce oxalates contents but still provided some good nutrition to healthy, (3) differences of the cultivation methods on oxalates content in some vegetables, in order to look for suitable cultivating method of vegetables.                 Key words: calcium oxalate, crystals, reduction, distribution, and formation

Abstract

Dalam masalah distribusi guru misalnya, kita belum mampu untuk menyebarkan guru SD secara merata hingga ke pelosok tanah air. Padahal, jumlah guru SD secara keseluruhan tidaklah termasuk kurang. Akibatnya, terjadilah kekurangan guru secara lokal di mana-mana, khususnya di daerah kecil, sulit dan terpencil. Dalam masalah disparitas kualitas, basil belajar rata-rata murid SD di kota-kota besar umumnya jauh lebih tinggi daripada rekan-rekan mereka di daerah terpencil. Mungkin yang lebih tepat dituding adalah karena kita belum menemukan teknik yang tepat untuk melakukan Pengelolaan Kelas Rangkap (PKR). Memahami hakikat atau esensi PKR, diharapkan tidak lagi memandang PKR sebagai suatu masalah yang sulit diatasi. Sebaliknya, dalam diri akan tumbuh pemahaman bahwa PKR adalah suatu tantangan yang pasti dapat diatasi. Adapun tujuan dilakukannya penelitian ini  adalah untuk mengetahui  cara pengelolaan kelas untuk Sekolah Dasar yang  mengalami kekurangan  guru di  daerah  perbatasan atau  terpencil Provinsi Kalimantan Timur yang terjadi selama ini, untuk mengetahui permasalahan apa yang terjadi dengan pola pembelajaran yang selama ini dilaksanakan di Sekolah Dasar yang mengalami kekurangan guru di daerah perbatasan atau terpencil Provinsi Kalimantan Timur dan mengembangkan model untuk mengatasi permasalahan yang terjadi pada pembelajaran yang selama ini dilaksanakan di Sekolah Dasar yang mengalami kekurangan guru di daerah perbatasan atau terpencil provinsi Kalimantan Timur.Model pengembangan mengikuti model Dick&Carey dengan langkah-langkah melakukan identifikasi tujuan pembelajaran, analisis pembelajaran, analisis karakteristik siswa, merumuskan indicator pembelajaran, mengembangkan butir tes, mengembangkan strategi pembelajaran, mengembangkan dan menyeleksi bahan ajar, merancang evaluasi formatif dan melakukan revisi bahan ajar. Model pengelolaan kelas yang sesuai untuk mengatasi permasalahan di SD pulau sebatik akibat mengalami kekurangan guru adalah model pengelolaan kelas 221 dalam artian guru mengajar dua kelas, dua mata pelajaran di dalam satu ruangan. Model ini dianggap sesuai dengan keadaan di pulau sebatik yang belum pernah menerapkan model pengelolaan kelas rangkap karena model pengelolaan 221 adalah model yang paling sederhana dari ketiga model dalam pengelolaan kelas rangkap.  Kata Kunci: Model, Pengelolaan Kelas, Sekolah Dasar, Kekurangan Guru, Perbatasan Terpencil
