Abstract

Porous media, solid substances with a number of coids through which fluids may flow are effective to transfer heat from the medium to fluid. A research was conducted to assess the effect of vacuum in reducing temperature of various types of porous media. Three different particle types, i.e. Well rounded gravel (smooth surface), 2<f<3.6 mm; Coarse sand, angular surface 3.6<f<5 mm, and Fine sand f<2 mm were packed into a tubular plastic support, respectively, through which water was flown Each of these was treated with vacuum with P of -5, -52, -55, and -56 cm Hg for the well rounded gravel; with P of -42, and -10 cm Hg for the angular coarse sand and P of -40 cm Hg for the fine sand. The ability of lowering the temperature of porous media varied from 5 to 14 centigrade, and the time required were dependant mostly on the types of particles and vacuum levels. The fine sand was unable to reduce the temperature, while the angular coarse sand was able to lower the temperature by les tha 5 centigrade. On the other hand, the well rounded gravel particle with smooth surface was able to lower temperature form 26 oC to 13 oC. The levels of vacuum which determined the flow rates of the air and water passed to the porous media, however, did not show any significant effect to the reduction of temperature. It was found that the particle arrangement configuration in the support, which mostly affect the total surface area as well as the flow rate of air are likely to be the dominant factors in temperature lowering. Keywords: Porous media, vacuum, temperature lowering

Abstract

The institutions of ECD (Early Childhood Development) have a vital role in a nation education sector because they are the very first institutions to instill educational values to learners, either religious values or universal values. The management of ECD institutions has been seemingly considered less important or less prestigious compared with the management of higher education institutions such as high school or university level. This paper portrays the activity results of Community Service Program focusing on early childhood development in the Garawangi and Rancaputat village, Sumberjaya District, Majalengka. This paper is expected to increase the awareness of all parties regarding the importance of early childhood education management,  particularly in financial management aspect. In addition, it is expected to add insight about the Community Service Program with a focus on small institution in village such as early childhood development. Keywords: early childhood development, Garawangi, Rancaputat, Financial Management of Small Institutions

Abstract

Biodiversity of Cyanobacteria from several ponds/lakes of Jakarta-Depok-Bogor, Indonesia. Research about the exploration on Cyanobacteria diversity from several ponds/lakes of Jakarta-Depok-Bogor area was done. Five research locations were Sunter 2 Lake of North Jakarta, Babakan Pond of South Jakarta, Ulin-Salam dan Agathis Pond at UI Campus of Depok, dan Lido Lake of Bogor. Samples were taken by purposive sampling, and samples analysis using subsample methode. The sampling times were on August to September 2006. Three types of samples which were taken were planktonic samples, epifitic samples, and waters bank soil samples. The results showed that several toxic potential Cyanobacteria were found in several waters, even they were dominant at Sunter 2 Lake dan Agathis Pond (UI Campuss). Based on similarity levels of Cyanobacteria, the five of waters could be classied into 3 group, i.e. Sunter 2 Lake and Agathis Pond, Babakan dan Ulin-Salam Pond, dan Lido Lake. Lido Lake waters was very unique on distribution and diversity of Cyanobacteria. Based on diversity Index (H’) of Cyanobacteria, several waters condition could be catagories as moderate waters, i.e. Babakan, Situ Ulin-Salam, and Situ Agathis Pond. The epifitic and waters bank soil Cyanobacteria which were found were also found as planktonik species except Oscillatoria sp. 3. At least 26 isolate of Cyanobacteria were acquired such as Miicrocystis, Oscillatoria, Gloeocapsa, Merismopedia, Planktothrix, dan Arthrospira.

Abstract

Kuliner adalah hasil olahan yang berupa masakan. Masakan tersebut berupa lauk pauk, makanan (penganan), dan minuman. Karena setiap daerah memiliki cita rasa kuliner tersendiri, maka tak heran jika Kota Samarinda yang dihuni oleh berbagai macam suku memiliki kuliner yang berbeda-beda. Berdasarkan itu maka perlunya merencanakan suatu kawasan kuliner di Kota Samarinda dengan menjadikan Sungai Mahakam sebagai brand dari kawasan itu. Dalam melakukan pendekatan perancangan ada beberapa tahapan penelitian studi yang harus dilakukan antara lain pendekatan tipologi objek, pendekatan tematik, pendekatan analisis tapak dan lingkungan. Metode pengumpulan data yang dilakukan dalam perencanaan ini menggunakan  beberapa metode yaitu sebagai berikut studi literatur, wawancara, pengamatan langsung. Dari hasil penelitian ini terciptanya suatu perencanaan kawasan kuliner dengan konsep bangunan dan kawasan open space, sehingga desain arsitektur yang dihasilkan akan mengedepankan Sungai Mahakam sebagai brand dari kawasan kuliner dengan konsep waterfront tersebut.

Abstract

Setiap individu memiliki kewajiban untuk menjaga kesehatannya agar dapat hidup dengan kualitas yang baik. Salah satu cara untuk menjaga kesehatan yaitu dengan melakukan aktivitas fisik. Namun, mahasiswa dengan segala aktivitasnya ditemukan memiliki jumlah aktivitas fisik yang kurang dari standar minimal. Kondisi tersebut juga berlaku  sbagi mahasiswa Universitas Padjadjaran. Untuk dapat meningkatkan aktivitas fisik pada mahasiswa, diperlukan suatu promosi kesehatan berupa edukasi untuk meningkatkan pengetahuan dan kesadaran mahasiswa seputar aktivitas fisik. Edukasi dilakukan dengan membuat konten video wawancara bersama dokter dan membahas pentingnya aktivitas fisik serta video rekomendasi tempat dan jenis olahraga yang bisa dilakukan oleh mahasiswa Universitas Padjadjaran. Video kemudian dipublikasikan di Instagram @klinik.unpad, Klinik Pratama yang menjadi stakeholder dan ikut berkolaborasi pada kegiatan ini. Hasil kegiatan didapatkan adanya peningkatan pengetahuan dan kesinambungan penerimaan informasi bagi mahasiswa Universitas Padjadjaran, sehingga kegiatan ini dinilai cukup berdampak. Dampak tersebut dalam jangka pendek selama masa KKN kemudian diukur dari jumlah likes dan viewers. Namun, agar kegiatan dapat lebih menjangkau mahasiswa Universitas Padjadjaran dan lebih terukur, sebaiknya dibuat kegiatan lanjutan yang diselenggarakan secara offline. DOI: https://doi.org/10.32897/abdimasusb.v4i1.2705

Abstract

Islamic Bank is a bank that applies Islamic principles in running the business. Until 2015, there were 12 Islamic Bank in Indonesia; one of them already listed on the stock market. The purpose of this study was to analyze differences in the bank's soundness was assessed using a bank's risk profile, good corporate governance, income, and capital (RGEC) between listed Islamic Banks and the unlisted ones. Using the data period 2011-2015 used the independent t-test to test for differences. Statistical tests showed that there is no significant difference in credit risk as measured by NPF and Earning as measured by BOPO that represent cost efficiency between the two groups of companies. Listed Islamic banks have lower credit risk and greater efficiency than the unlisted onesDOI: 10.15408/aiq.v9i1.4011
