    In the frame of screening of the medicinal plants efficacy, 19 plants have been tested to see their influence to the normal body temperature of mice. Among the 19 plants there are some medicinal plants which are used as antipyretic by the Indonesian people. Those are Ageratum conyzoides L, Brasica rugosa Prain, Euphatorium triplinerve Vahl, Messua ferrea L and Oroxylum indicum Vent. The administration is intra-peritoneally. Some extract at test dose (1/3 - 1/2) LD 50 decrease the normal body temperature more than 2°C. Most of them happened to be known as antipyretic in traditional medicines

    This article presents the process of developing an effective learning model to improve teenagers' self-esteem and motivation of having achievement. The research used mixed method research. In developing the learning model, the researcher carried out pre-study, development and model validation, and a model testing. The research generated a theoretically and empirically proper learning model to improve teenagers' self-esteem and motivation of having achievement at pesantren (Islamic boarding school). The learning model which was generated is MPPHM (Model Pembelajaran Peningkatan Harga Diri dan Motivasi /The Learning Model to Improve Self-Esteem and Motivation). This model was able to create the interesting, pleasant, and challenging study ambience to be followed by students. The results showed that it generated pedagogic development, provided the efforts to solve a problem in improving teenagers' self-esteem and motivation of having achievement, and served as the input for plan, implementation, and development of pesantren or other education institutions. This study was expected to benefit the teachers, principals and parents to pay attention to their children psychosocial factor that influence their children behaviors

    Peatland has important role in wetland ecosystem stability. Depletion and disappearance of peat layer lead to loss of potential source of nutrient and disruption of wetland ecosystem stability. The research aimed to study the influence of peat thickness and land hydrological condition on the total nitrogen (N) content in soil, the influence of rapidly or naturally the depletion and disappear of peat layer on total N content in soil, and the influence of hydrological condition on total N content in soil. Total N was observed in June of 2009 and 2010 (transition from wet to dry season), September of 2009 and 2010 (peak of dry season), and January of 2010 and 2011 (peak of wet season). The research was carried out on potential acid sulphate soil (A), peaty acid sulphate soil (B),shallow peat which all of peat layers wereremoved (C), shallow peat which peat layer was partially removed (D), shallow peat (E), moderate peat (F) and deep peat (G). The results showed that total N content increased with increasing of peat thickness, the depletion and disappearance of peat layer reduced total N content in soil, and declining in the groundwater level increased total N content in soil

    Abrasi Pantai dan Pendangkalan Kolam Pelabuhan Jetty Pertamina Balongan, Indramayu melalui Analisis Arus Pasang Surut, Angin dan Gelombang

    Full text link
    Masalah utama yang terjadi di perairan sekitar kolam Pelabuhan Jetty Pertamina Balongan, Indramayu adalah abrasi dan pendangkalan. Oleh karena itu dilakukan analisis mengenai pendangkalan kolam pelabuhan dan abrasi pantai di lokasi ini dengan menggunakan data arus stasioner, trayektori arus, pasang surut dan hindcasting gelombang. Data penelitian lapangan selama satu bulan memperlihatkan telah terjadi proses pendangkalan dan abrasi pantai di sekitar area Pelabuhan Jetty Pertamina. Proses ini terjadi akibat terganggunya laju sedimen yang berasal dari selatan ke utara dan sebaliknya oleh aliran arus sejajar pantai dan arus pasang surut karena keberadaan Pelabuhan Jetty Pertamina (terganggunya kesetimbangan suplai sedimen). Kecepatan arus pasang surut pada tiga kedalaman berbeda rata-rata berkisar antara 0.168 – 0.215 m/s dan kecepatan arus terbesar sebesar 0.371 m/s terjadi pada saat spring tide. Arus pasang surut dan arus sejajar pantai secara bersinergi mempercepat terjadinya abrasi pantai dan pendangkalan kolam Pelabuhan Jetty. Laju abrasi pantai di perairan ini berdasarkan data PPPGL tahun 2003 adalah sebesar 1 – 4 m per tahun. Salah satu upaya untuk menanggulangi abrasi dan pendangkalan di kolam Pelabuhan Jetty terlebih dahulu harus di lakukan studi pemodelan. Studi pemodelan ini digunakan untuk melihat gambaran secara dinamis kondisi hidro dinamika perairan yang berhubungan dengan proses terjadinya pendangkalan dan abrasi, serta untuk menentukan tipe bangunan pantai yang sesuai. Kata kunci : pelabuhan, jetty, sedimentasi, pendangkalan, abrasi, arus, sedimen The main problem that occured around the pool of port Pertamina Jetty Balongan, Indramayu is abrasion and shoaling. Therefore an analysis of the shoaling pool of port and coastal abrasion in this location was conducted by using the stationary current data, trajectory current, tide and wave hindcasting. Data of one-month field observation shows there has been shoaling and coastal abrasion processes in the areas sorrounding port Pertamina Jetty. This process occurs due to disruption of the rate of sediment derived from south to north and vice versa by the current flow parallel to the coast and tidal current because of the presence of Pertamina Jetty port (disturbance of equilibrium sediment supply). The velocity of tidal currents on three different average depths ranging from 0.168 – 0.215 m/s and the largest flow velocity of 0.371 m/s during spring tide. The direction of static current measurement and float tracking south-southeast trending dominant at low tide and northwest-north at high tide. Tidal current and longshore current sinergies to accelerate the occurence of coastal abrasion and shoaling pool of Harbour Jetty. The rate of coastal abrasion in this water based on PPPGL data of 2003 that is 1 – 4 m/s per year. One effort to overcome abrasion and shoaling in pool Harbour Jetty should be done prior modeling studies. This modeling study is used to portraya water hydro dynamics associated with the process of shoaling and abrasion, as well as determine the appropriate types of coastal structures.
