Judul: The Model of Physical Exercise Effect on the Dynamics of Glucose and Insulin
Abstrak: Regular physical activity is indicated either to prevent or delay the onset of non-insulin-dependent diabetes or to assure a good control of diabetes by increasing insulin sensitivity and ameliorating the metabolism of glucose disappearance. A minimal model developed previously was extended to include the major effects of exercise on plasma glucose and insulin levels. Minimal model of glucose and insulin dynamics created in this study is valid. Result of model simulation is good agreement with experimental data. On the normal subject, physical exercise can reduce blood glucose levels, the same thing happened in people with diabetes. In general, the model can be explained that physical exercise can lower glucose levels basal while after the exercise, but will eventually rise returned to initial basal glucose levels, so to keep the blood glucose remained normal should be done exercise regularly and with the assistance of insulin therapy appropriate to the needs of patients.

Judul: Pengaruh Latihan Fisik pada Penderita Diabetes Tipe 1 dan Tipe 2 dengan Minimal Model Termodifikasi
Abstrak: Modified minimal model with the addition of two parameters, such as the effect of physical exercise to improve blood glucose missing and the effect of physical exercise to increase the secretion of insulin from the pancreas. This modified can be used as a simulator system reliable in analyzing glucose and insulin in healthy and diabetic conditions. It is seen from the simulation results in this study that the presence of physical exercise can lower glucose concentrations and increase insulin sensitivity. Type of physical exercise in type 2 diabetes can be divided into two, namely mild and strong. SI values in type 2 diabetes without exercise of 1.2×10-7 μU ml-1 min-1 and with mild physical exercise 2.974×10-4 μU ml-1 min-1 and strong physical exercise 3.9005×10-4 mlμU-1min-1. On the other hand in patients with type 1 diabetes physical exercise alone is not enough to lower the glucose concentration to basal glucose levels so it takes a shot. In this study, exogenous insulin type 1 diabetes at 50 and after physical exercise combined with exogenous insulin requirement was reduced to 40 % . In type 1 diabetes , physical exercise can also increase insulin sensitivity to near healthy range. SI value without physical exercise 5.3×10-7 μUml-1min-1 and after physical exercise 3.0111×10-4 μU ml-1 min-1.

Judul: Diversity of Crabs (Decapoda: Brachyura: Portunidae) in the Arafura Sea
Abstrak: Laut Arafura merupakan laut dengan luas 650.000 km2 dengan maksimal kedalaman 3,68 km yang berada di wilayah Propinsi Papua. Kepiting merupakan anggota filum Arthropoda, kelas Malacostraca, Ordo Decapoda, dan Subordo Brachyura. Brachyura yang sering disebut sebagai kepiting sejati merupakan hewan yang sangat beragam pada tingkat infra-ordo. Kepiting berperan sebagai bentos dan spesies kunci, berperan dalam keberlangsungan rantai makanan. Brachyura yang sudah dilaporkan di dunia berjumlah 7250 spesies, adapun spesies yang dilaporkan di Indonesia oleh Kementrian Lingkungan Hidup dan Kehutanan Indonesia sekitar 1400 spesies. Penelitian ini bertujuan mengetahui dan mendeskripsikan spesimen kepiting (Portunidae) yang tertangkap dari Laut Arafura. Metode yang dilakukan adalah mengidentifikasi beberapa spesimen koleksi Prof. Dr. Ali yang berada di Departemen Biologi, IPB University. Spesimen diidentifikasi menggunakan FAO Species Identification Guide for Fishery. Nomenklatur spesies berdasarkan laman World of Registered Marine Species (WoRMS). Berdasarkan hasil pengamatan morfologi yang dilakukan pada spesimen, diperoleh delapan spesies kepiting dari famili Portunidae yaitu, Eodemus unidens; Charybdis (Charybdis) lucifer; Lupocycloporus wilsoni; Charybdis (Archias) hongkongensis; Lupocycloporus gracilimanus; Charybdis (Charybdis) callianassa; Charybdis (Archias) omanensis septentrionalis; dan Charybdis (Charybdis) anisodon., The Arafura Sea is a sea with an area of 650,000 km2 with a maximum depth of 3.68 km in the Papua Province. Crabs are members of the phylum Arthropoda, class Malacostraca, Order Decapoda, and Susubdo Brachyura. Brachyura, often referred to as true crabs, are very diverse animals at the infra-order level. Crabs act as benthos and key species, playing a role in the sustainability of the food chain. Brachyura that has been reported in the world amounts to 7250 species, while the species reported in Indonesia by the Indonesian Ministry of Environment and Forestry are around 1400 species. This study aims to know and describe crab specimens (Portunidae) caught from the Arafura Sea. The method carried out is to identify several specimens collected by Prof. Dr. Ali who are in the Department of Biology, IPB University. Specimens were identified using the FAO Species Identification Guide for Fishery. Species nomenclature based on the World of Registered Marine Species (WoRMS) page. Based on the results of morphological observations made on specimens, eight species of crabs from the Portunidae family were obtained, namely, Eodemus unidens; Charybdis (Charybdis) lucifer; Lupocycloporus wilsoni; Charybdis (Archias) hongkongensis; Lupocycloporus gracilimanus; Charybdis (Charybdis) callianassa; Charybdis (Archias) omanensis septentrionalis; dan Charybdis (Charybdis) anisodon.
