Abstract

Social media utilization by moslem community has increased from year to year. In the last decade, Facebook and Twitter are used as means of communication to forward the religious messages and Islamic preaching (dakwah). Among existing social media, twitter is considered having quite high popularity in society. Trend of conducting dakwah by twitter with kultwit apparently has assisted the Muslim preachers to deliver Islamic messages in more interesting way. Furthermore, they gain positive respond from society. Kultwit has become one of the alternative sources to obtain information about Islam and to understand Islam deeper.

Abstract

Adsorption of carbon dioxide is a vital process in biogas purification. A previous study has narrowed down the choice of ion exchange resins for the adsorption process into two commercial resins, Dowex Marathon A, and Purolite. Dowex Marathon A boasts the advantage of having no need of any pretreatments to use. Purolite, although needing pretreatment before usage, costs only roughly a third of Dowex Marathon A. The objective of the study is to decide on which resin is best suited to commercially produce biogas free from pollutants, most of which is carbon dioxide. Both resins at their fresh state were tested for durability by checking on levels of carbon dioxide content at set time intervals. Results suggest the Purolite resin to be more durable than the Dowex Marathon A resin. Data of gas passing through Dowex showed relatively high concentration of CO2 after 10 minutes of operation. While Purolite showed its first signs of CO2 after 20 minutes of operation. Further tests are conducted to compare fresh and regenerated Pirolite resins. Comparison between fresh and postregeneration Purolite showed relatively consistent results where the regenerated resin showed its first signs of CO2 after 25 minutes.

Abstract

The emphasis of the agricultural industry in Indonesia lies in the program of increasing food security, agribusiness development and improving the welfare of farmers. The priority of food security in establishing the independence of farmers in maintaining local resources efficiently and optimally, so that resources can be utilized further. The objectives of the research are to mapping the leading food processing industry, the determination of the leading local resources, the formation of documentation and the making of Geographic Information System (GIS) application to support the improvement of food processing industry in order to independence and food security, the growth and development of food industry in the region. The method of conducting research with data collection of food processing industry in Central Java Province by making data base and taxonomy, mapping of food processing industry in regency/city and making of digital portal with feature of data component of food processing industry to more introduce superior food processing industry to the public. The achieved results are documentation of leading food processing industry and GIS formation for all regencies/cities of Central Java Province, to encourage the improvement of food processing industry, real industrial income, processing quality and increasing self-sufficiency of food processing industry.

Abstract

Pada tahun 2015, dengan perkiraan populasi 255 juta orang, Indonesia membutuhkan lahan seluas 13,38 juta hektar. Artinya, dalam beberapa tahun kedepan, Indonesia akan mengalami krisis lahan pertanian sehingga Indonesia dituntut untuk meningkatkan total areal budidaya. Hal ini disebabkan oleh meningkatnya perkembangan industri dan jasa, sehingga pertanian konvensional kurang kompetitif karena tingginya harga tanah. Salah satu pengembangan teknologi pertanian pertanian disebarkan teknologi budidaya pertanian yang layak dengan teknologi smart growbox memberikan alternatif bagi mereka yang tidak memiliki lahan untuk pertanian. Desain smartbox dengan sistem pemantauan suhu dan kelembaban melalui internet telah dirancang, dengan menggunakan sensor suhu dan kelembaban (DHT22) serta sensor kelembaban tanah (FC-28), maka kondisi tanaman dan lingkungannya akan mudah dipantau oleh melihat nilai output dari sebuah sensor. Hasil pengujian kecepatan rata - rata respon manual control via perangkat berbasis web adalah 5 detik. Kontrol kecepatan respon secara manual tergantung pada lalu lintas jaringan dan kondisi jaringan. Sistem siap untuk digunakan.

Abstract

One of the success factor for hatching egg was egg turning on home made egg hatcher classification. These were average four egg turnings needed to hatching egg during 70% days of hatching times. For egg turning, if conducted one by one, there were opportunities off falling off, moreover leads to failure and longer period of time. Using hollistic approach on egg turning, that were added on egg turning tools, the egg turning can be done as whole series in less than two seconds.

Abstract

Secara umum, 70% berat komponen otomotif terbuat dari bahan aluminium, produk-produk otomotif terbuat dari bahan aluminium yaitu ; piston, blok mesin, kepala silinder, velg dan sebagainya. Dalam penggunaan bahan aluminium  pada komponen otomotif, perlu memiliki nilai kekuatan mekanik yang baik. Produk dari bahan logam aluminium dapat dibuat dengan melakukan rekayasa material  dengan melakukan campuran paduan seperti: Cu, Si, Mg, Zn, Mn, Ni, dan sebagainya. Penelitian ini bertujuan untuk menganalisis tegangan tarik dan modulus elastisitas bahan Al-Si dari bahan piston diesel bekas. Pengujian impak bertujuan untuk menentukan ketangguhan material  aplikasi manufaktur  swingarm sepeda motor . Proses remelting piston diesel dilakukan peleburan dengan variasi penambahan unsur magnesium (Mg) dengan variasi  0, 2, 3, dan  5%. Peleburan aluminium Al-Si menggunakan cetakan pasir dan membuat spesimen uji dengan standardisasi ASTM-E8M untuk uji tarik dan ASTM-E23 untuk uji impak. Hasil yang diperoleh dalam pengujian tarik dan impak ditujukan untuk memperoleh kekuatan tarik, modulus elastisitas dan keuletan. Optimasi penambahan unsur Mg sebesar 3% dapat menghasilkan sifat  paduan  Al-Si yang lebih baik.

Abstract

Dual Homing ONT mechanism implemented by PT. XYZ to establish Node B BTS network. This mechanism has reliability benefit due to dual uplinks support it has, so when one of the dual uplinks goes down, the backup link will then getting active and forwarding data. At this time, current market available monitoring system unable to detect failure on both uplinks when one of them inactive due to system failure. This problem occurs because device probing could only be established up to ONT. In this case, engineer does not aware whether their link is up or not, and dual homing scheme does not really works. Due to problem which is explained above, this paper offers a new approach to monitor two target of each ONT: the IP address and the logical port of the OLT where the ONT connected. In this mechanism, if one of the link fail, system will send an alert to engineer based on the status of the logical port to repair the broken link.

Abstract

On examination using  USG ( ultrasonography), gel carbomer 940 applied on body surface has role as acoustic coupling agent between USG probe and body surface. The function of this gel is to transmit   ultrasonics wave from probe to body without resisted by the air. Gel carbomer 940 is a non biodegradable matter. For decreasing the content of non biodegradable part of carbomer 940, in this research, the extract of aloe vera was added into gel carbomer 940. To know the efficiency of ultrasonics energy tramsmitted to the body, transmitansi coefficient measurement is required.. Transmitansi coefficient can be calculated from ultrasonics velocity value in the gel. The velocity measurement use transmit time method with equipment the ultrasonics thickness gauge AR860 connected to osciloscope. Examanation of the coefficient was carried out in  first and 12 th week. The results indicated the acoustic impedance and the transmitansi coefficient decreased by adding of aloevera content. However at 12 th week the influence of aloe vera relatively did not give effect to the gel carbomer transmittance.
