"Senyawa tanin merupakan salah satu jenis senyawa polifenol yang memiliki aktivitas inhibisi terhadap enzim xanthine oxidase. Enzim ini merupakan senyawa yang berperan dalam pembentukan asam urat dalam tubuh. Adanya overproduction atau underexcretion dari asam urat dapat menyebabkan timbulnya keadaan hiperurisemia yang mengakibatkan penyakit pirai atau encok. Penelitian ini bertujuan untuk mengkaji pengaruh variasi pelarut (aseton 70%, etanol 70%, dan akuades) terhadap ekstraksi senyawa tanin dengan metode sonikasi, serta aktivitas inhibisi ekstrak tanin terhadap enzim xanthine oxidase. Proses ekstraksi yang dilakukan terhadap daun putri malu menghasilkan ekstrak kasar terbanyak dengan pelarut akuades, yaitu sebesar 3,9% massa. Aktivitas inhibisi tertinggi juga dihasilkan oleh ekstrak kasar akuades, yaitu sebesar 24,6% yang berkorelasi dengan konsentrasi senyawa tanin sebesar 2,07 mg/g.

Tannin is one of the polyphenolic compound that exhibits inhibitory activity to xanthine oxidase enzyme. This enzyme plays an important role in the formation of uric acid in the body. Any overproduction or underexcretion of uric acid may lead to hyperuricemic condition that will results in gout.

This study is aimed to assess the effect of solvent variation (70% acetone, 70% ethanol, and water) on tannin extraction with sonication method, as well as the extract's inhibitory activity against xanthine oxidase enzyme.

The extraction process performed on the leaves of Mimosa pudica results in the highest yield extract from water solvent, which is 3.9% weight percentage. The highest inhibitory activity is also generated by the crude water extract, which is 24.6%, correlating with a tannin concentration of 2.07 mg/g."

"This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. "

"A first part deals with the morphology and taxonomy of the genus and a classification based on the biological species concept is presented. A further part is devoted to the author’s research accomplishments in this genus. It describes morphological characters distinguishing between diploids and tetraploids of series Eubarbatae, the genetic relationships between them, and the mode of origin of the tetraploid form. The section Denticulatae, to which the common oat belongs, is extensively treated. Further, oat domestication and the newly domesticated protein rich A. magna are described. A third part deals with wild genetic resources of oat."

"ABSTRAKPenelitian ini membahas mengenai proses pemberdayaan ibu rumah tangga anggota kelompok wanita tani Matahari dalam pemanfaatan lahan pekarangan untuk pengembangan tanaman obat keluarga sebagai upaya perubahan kondisi ekonomi keluarganya. Ibu rumah tangga merupakansalah satu komponen sumber daya manusia dalam pembangunan sosial dan ekonomi, terutama yang tergabung dalam kelompok wanita tani.Proses pemberdayaan di komunitas ibu rumah tangga menjadisalah satu kegiatan di Kota Administrasi Jakarta Timur dalam program percepatan penganekaragaman konsumsi pangan.Dalam pelaksanaan program pemberdayaan ibu rumah tangga tersebut di lakukan melalui beberapa tahap. Adapun tahap-tahap yang dilalui antara lain adalah tahap persiapan dan penjalinan relasi, tahap pengkajian, tahap pelaksanaan program percepatan penganekaragaman konsumsi pangan, tahap pengkajian ulang, dan pengembangan program percepatan penganekaragaman konsumsi pangan. Penelitian ini dilakukan dengan menggunakan metode deskriptif dan pendekatan kualitatif. Penelitian ini dilaksanakan dengan mengambil tempat dan informan di wilayah lingkungan RW 09 Kelurahan Kebon Pala, Kecamatan Makasar, Kota Administrasi Jakarta Timur.Hasil yang didapatkan dari penelitian ini adalah bahwa proses pemberdayaan ibu rumah tangga yang tergabung dalam kelompok wanita tani, menciptakan perubahan kondisi ekonomi keluarga anggota kelompok wanita tani dan juga memberikan manfaat lingkungan hidup yang asri dengan pemanfaatan lahan pekarangan. Selain itu, penelitian ini juga mengidentifikasi tanaman obat keluarga yang menjadi unggulan dalam budidaya tanaman obat.

ABSTRACTAbstract This study discusses about proces empowerment housewife as a member of women farmers Matahari in utilizing the house yard to the develop of family medicinal plants in an effort to change their economic condition, is one component of human resources in social and economic development.The empowerment processes of housewives communities will become one of the focal point in activities program of East Jakarta Administration in accelerate diversification of food consumption.For the implementation is through several stages, follows preparation phase and interlacement relations, implementation phase to accelerate diversification of food consumption, stage of the review and development program to accelerate diversification of food consumption. This research usesqualitative approach with descriptive design and qualitative method, the implementation took place and informants at RW 09 Kelurahan Kebon Pala, Districs Makasar of East Jakarta Administration. This empowerment process creates changes in economic conditions of the members of the group. "

"Significant changes over the past decade in computing technology, along with widespread deregulation of electricity industries, have impacted on power plant operations while affording engineers the opportunity to introduce monitoring and plant-wide control schemes which were previously unfeasible. Contributors of world-class excellence are brought together in Thermal Power Plant Simulation and Control to illustrate how current areas of research can be applied to power plant operation, leading to enhanced unit performance, asset management and plant competitiveness through intelligent monitoring and control strategies."
