    The Cabinet-type ERK solar dryer is manufactured by a temperature distribution process so that the temperature inside the appliance is well distributed. The cabinet-type ERK solar dryer comprises several components to maintain the water content, including a drying oven, air blower, heat-resistant pipe, hot water pump, thermostat, heat exchanger, and heater. These tools are used to convert heat radiation into conduction or convection so that the dried agricultural products' water content is relatively low. The data needed to show the quality of the tool include temperature on temperature received by the wall (Tw), absorbent plate (Tp) and room temperature (Tr). And as for other supporting data including the environmental air/ ambient temperature (Ta) and solar irradiation (I) for optimal tool usage time. The experiment results for 5.5 hours, as many as 23 measurements with time interval 15 minutes, obtained a relatively unchanged temperature distribution. During that time, the average temperature received by the wall (Tw) was 41.26 Â°C, while the middle plate temperature (Tp) was 40.65 Â°C and room temperature (Tr) was 40.71 Â°C. Thus, the temperature in the Cabinet-type ERK solar dryer is well distributed. The distribution percentage between wall temperature and plate temperature is 98.52 %, while wall temperature and room temperature are 98.67 %. The result indicates that the Cabinet-type ERK solar dryer is potential as a drying device for agricultural commodities. It is hoped that the Cabinet-type ERK solar dryer will be an alternative to a drying system that can improve the quality of agricultural commodities for farmers in Indonesi

    Treatment Limbah Industri Pulp dengan Metode Filtrasi untuk Menjaga Kualitas Air DAS Ciujung

    Get PDF
    Minimalisasi limbah merupakan implementasi untuk mengurangi jumlah dan tingkat cemaran limbah yang dihasilkan dari suatu proses produksi dengan cara pengurangan, pemanfaatan dan pengolahan limbah. Pada penelitian ini, treatment terhadap limbah pulp dilakukan dengan metode filtrasi. Dalam memberikan perlakuan terhadap limbah pulp melalui metode filtrasi dilakukan dalam dua tahapan. Pertama, mengkaji dan mengoptimalkan sisa hasil produksi. Kedua, mendesain filter yang berfungsi untuk meminimalisasi kadar limbah sebelum dibuang ke sungai, sehingga kualitas air sungai tetap terjaga. Hasil pengukuran konsentrasi pencemar setelah dilakukan filtrasi, terjadi pula penurunan konsentrasi di beberapa titik sampling. Konsentrasi pencemar dipengaruhi oleh debit limbah yang dibuang dari industri ke sungai. Dalam menganalisis konsentrasi pencemar di Daerah Aliran Sungai (DAS) Ciujung menggunakan nilai kondisi awal (initial conditions) dan nilai kondisi batas (boundary conditions) sebagai input model

    Awan cumulonimbus merupakan jenis awan berbahaya yang dapat menimbulkan cuaca ekstrim seperti hujan deras, kilat dan guruh. Jenis angin yang dapat mempengaruhi adanya awan cumulonimbus adalah Vertical wind shear, dengan adanya angin ini dapat menentukan jenis badai yang terjadi. Apakah termasuk kedalam badai dengan intensitas yang hebat atau tidak. Karena semakin besar Vertical wind shear akan semakin besar juga intensitas badai yang terjadi akibat adanya awan cumulonimbus. Untuk mengetahui keterkaitan Vertical wind shear pada pertumbuhan awan cumulonimbus maka diadakannya penelitian ini  menggunakan metode data cuaca permukaan dan menggunakan metode data cuaca permukaan ini kemudian diolah menggunakan Minitab dan Wind Rose. Setelah di analisis dan diolah menggunakan beberapa software dan perhitungan menggunakan dry adiabatic lapse rate dapat ditemukan terjadinya Awan cumulonimbus yang disertai intensitas curah hujan klasifikasi sedang terdapat pada tanggal 24 Februari 2020 dengan arah angin terbanyak dari sebelah barat yang secara topografi wilayah Kabupaten Tangerang berbatasan langsung dengan Kabupaten Serang dan Lebak, Banten. Hasil pengujian menggunakan software minitab dan juga windrose yang memanfaatkan data cuaca permukaan di Stasiun Meteorologi Budiarto Curug, terbentuknya awan cumulonimbus hingga terjadi hujan memiliki variasi arah angin yang berubah-ubah dari sudut 45? sampai dengan 124? menandakan adanya arah angin yang berubah-ubah dan menimbulkan terjadinya awan cumulonimbus. Suhu yang terukur pada bola kering atau disebut dengan suhu saat ini menunjukkan nilai 21,9? C sampai dengan 30,8? C mengalami penurunan suhu akibat terjadi hujan. Hujan yang terjadi akibat adanya awan cumulonimbus berlangsung selama 2 jam, dengan intensitas curah hujan sebesar 118,6 mm dan dikategorikan sebagai hujan sedang
