Research on the Study of Cocoon Production and Viability of Pontoscolex corethrurus Fr. Mull at various concentrations of Karbaril insecticide was carried out in July to October 2019, at the Laboratory of Animal Physiology, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Inderalaya, Ogan Ilir, South Sumatra. This study aims to study the production of cocoon and viabiltas earthworm Pontoscolex corethrurus Fr. Mull at various concentrations of carbaryl insecticide as well as getting concentrations of carbaryl insecticide began to react to the amount of cocoon and viability of the earthworm Pontoscolex corethrurus Fr.Mull. Contribution of research on the availability of data on the production of cocoon and viabiltas cocoon of earthworm Pontoscolex corethrurus Fr.Mull after being given various concentrations of carboxyl insecticide and providing information especially to farmers about the effect of various concentrations of carbaryl insecticide on non-target animals, especially soil animals namely Pontoscolex corethrurus Frethrurus earthworm . Mull. This study uses a completely randomized design with 6 (six) treatments and 5 (five) repetitions. The treatment given in the form of carboxyl insecticide with a concentration of 0% (control); 0.1%; 0.2%; 0.3%; 0.4%; 0.5%. Data were analyzed by Analysis of Variance, if there were significant differences followed by Duncan's Test at a 95% confidence level. The results showed that the treatment of various concentrations of carboxyl insecticide significantly affected the average number of cocoon and viability of the earthworm cocoon Pontoscolex corethrurus Fr. Mull. Average number of earthworm cocoons Pontoscolex corethrurus Fr. The lowest Mull was found in the administration of carboxyl insecticide at a concentration of 0.5%, 0.62 Â± 0.06 cocoon / individual / week and the average number of earthworm cocoons Pontoscolex corethrurus Fr. The highest Mull was found in the administration of carboxyl insecticide at a concentration of 0% (control), namely 3.62 Â± 0.02 cocoon / individual / week. The average viabiltas cocoon of earthworms Pontoscolex corethrurus Fr. The lowest Mull was found in the administration of carboxyl insecticide at a concentration of 0.5%, namely 18.85 Â± 1.19% and the average viability of the earthworm cocoon Pontoscolex corethrurus Fr. The highest Mull was found in the administration of carboxyl insecticide at a concentration of 0%, namely 98.65 Â± 2.15%

Telah dilakukan penelitian tentang pengaruh berbagai jenis karbohidrat pada pakan buatan lengkap terhadap pertambahan berat dan periode makan larva Spodoptera exempta instar akhir (V). Larva dipelihara dengan pakan alami (buncis). Metoda yang digunakan adalah metoda makan tanpa pilih dengan pakan buatan lengkap yang berbeda jenis karbohidrat (sukrosa, fruktosa, glukosa, maltosa dan mannitol). Hasil penelitian menunjukkan bahwa sukrosa merupakan jenis karbohidrat yang paling baik dalam meningkatkan pertambahan berat larva dan juga memberikan periode makan yang paling pendek terhadap larva Spodoptera exempta.

Waders migrate to maintain survival, to find new food sources and avoid extreme environmental changes. Waders population in a location varies according to environmental conditions. The study was con-ducted using the point count method. The observation time of each location is 30 minutes with repetition 3 times. There are four observation locations, namely Bungin River Estuary, Solok Buntu Estuary, Barong Kecil River Estuary, and Siput River Estuary. Data analysis technique uses correlation analysis. The results showed the number of wader birds at the end of the season migration in the Siput River Estuary was 886 individuals, while the Barong Kecil River Estuary was 536 individuals, Bungin River Estuary 140 individuals, and Solok Buntu Estuary 105 individuals. Tringa totanus, Limosa laponica, and Numenius arquata can be found at each observation location. Wader birds population found correlated with macrozoobenthos density had a correla-tion coefficient of 0.73.

Swamp buffalo (Bubalus bubalis) is a germ plasm specific of Pampangan and endemic in South Sumatera with low productivity and limited distribution. The aims of this study was to obtain information regarding biophysical conditions in the central areas of swamp buffalo in South Sumatera. The method used is purposive sampling method. Data collected in the form of quantitative and qualitative. Primary data were obtained through direct observation, interviews breeders selected as respondents while secondary data obtained from various related. The data obtained are presented descriptively and data tabulation. Productivity of swamp buffalo Pampangan can be increased by managing and maintaining habitat conditions although traditional maintenance. The results of observations of the biophysical condition of swamp buffalo (B. bubalis) Pampangan showed that habitat of swamp buffalo Pampangan consists of dominated by lowland swamp area is overgrown with shrubs and grass. The conclution of the research are productivity and population of swamp buffalo (B. bubalis) pampangan as specific plasma nutfah of South Sumatra can be improved by studying the characteristics and preferred habitat of the buffalo, although developed in a traditional farms but is good enough and so need to be developed, grass is most preferred by swamp buffalo Pampangan derived from ‘Kumpai’ grass group, and ‘Kasur’grass and ‘Kumpai’ grass is the dominant grass type found in habitat swamp buffalo Pampangan.

Eggshell is a solid waste that is available in abundance but is being left unused. Eggshell containing calcium in a high amount. Calcium can be used as a precursor for hydroxyapatite (HAp). Modification of HAp with SiO2 is expected to improve its low mechanical properties for biomedical applications. In this study, HAp is synthesized from the eggshell. Then, it was modified by adding SiO2 utilizing the coprecipitation method with concentrations of 10%, 20%, 30%, and 40%, respectively. The HAp and HAp/SiO2 were characterized using; X-ray diffraction and Fourier transform infrared spectroscopy. The analysis HAp and HAp/SiO2 were density, compressive strength, and hardness. The best mechanical properties of HAp/SiO2 were characterized using SEM-EDS. The HAp were prepared successfully with a ratio of Ca/P was 1.673, close to the theoretical 1.67. The addition of SiO2 caused a decrease in crystallite size and density but increased compressive strength and hardness. The best mechanical properties of HAp/SiO2 were obtained with SiO2 of 30% and 40% with similar values.
