Abstract

ATM has one common feature which guarantees its success, namely the possibility to transport any ATM service, irrespective of its characteristics such as the bit rate, its quality requirements or its bursty nature. ATM also has high flexibility in allocate the bandwidth, and thus allows more calls to enter the network. Unfortunately, this advantage has a negative consequences. ATM presents congestion problems in the network as well as in the end terminals. This research describes about congestion control mechanism that will be applied for Available Bit Rate (ABR) Service in ATM networks, namely, the Rate-Based Congestion Control Scheme. This method supports end-to-end closed-loop control and has been indentified as the most appropriate for the support of this service by ATM Forum. ABR Service is a new ATM Service category. This kind of service automatically and dynamically allocates the available bandwidth to users by controlling the traffic flow based on feedback information. The source increases or decreases the source rate of cells transmission based on the information in the feedback Resource Management (RM) cell it receives. This method minimizes the duties of intermediate nodes and the destination node, so it is expected the source will receive the feedback information faster.

Abstract

Degradation of malachite green has been done. In this research, degradation process of malachite green was done by ozonolisis method, using TiO2- anatase and ZnO catalyst. The residu of malachite green was centrifuged and measured by spectroscopy UV / Vis at 200-800 nm after degradation. 6 mg / L malachite green diozonolisis for 5 minutes obtained pH optimum at pH 7. 6 mg / L malachite green was added 0.025 mg TiO2-anatase catalyst, and 0.025 mg ZnO at pH 7 with a variation time obtained optimum time of 5 minutes. Percent degradation of malachite green is generated by the addition of 0.0250 grams of TiO2-anatase 99.77% and 0.0250 grams of ZnO 93.59%. Percent of the results showed that the degradation of degradation with the addition of TiO2-anatase is greater than the addition of ZnO, because of the stability of TiO2- anatase is large.

Abstract

Penelitian ini merupakan kelanjutan dari penelitian sebelumnya. Penelitian sebelumnya telah berhasil mengukur variabel suhu, kelembaban, dan radiasi surya pada titik pengukuran 07o13’42,5’’ LS dan 109o17’13,2’’ BT di ketinggian 1264 m dpl. Variabel yang akan dihitung dalam penelitian ini adalah evapotranspirasi. Dalam perhitungan evapotranspirasi memerlukan berbagai data dari pengukuran sebelumnya dan data dari klimatologi. Selain itu, nilai kecepatan angin juga diukur untuk mengetahui pengaruhnya terhadap produktivitas buah stroberi. Penelitian ini bertujuan untuk mengetahui pengaruh kecepatan angin dan evapotranspirasi terhadap kualitas buah stroberi. Kecepatan angin diukur secara langsung dengan alat Anemometer dengan rentang waktu 1 jam selama 24 jam. Sedangkan nilai evapotranspirasi dihitung dengan metode Penman menggunakan data-data pendukung yang telah diukur dan diketahui pada penelitian sebelumnya. Selanjutnya, dimodelkan nilai kecepatan angin terhadap waktu serta nilai evapotranspirasi terhadap waktu sebelum dan setelah interpolasi menggunakan Matlab dalam bentuk kurva 2D. Interpolasi digunakan untuk menentukan data-data yang belum terukur diantara data terukur. Nilai kecepatan angin maksimum yang diperoleh adalah 6,9 m/s, sedangkan evapotranspirasi maksimum 12,3 mm/hari dan minimum 9,2 mm/hari. Kecepatan angin memegang peranan penting dalam proses evapotranspirasi. Laju evapotranspirasi sebanding dengan kecepatan angin. Semakin tinggi kecepatan angin maka semakin tinggi nilai evapotranspirasi. Nilai kecepatan angin dan evapotranspirasi berpengaruh terhadap tinggi rendahnya produktivitas buah stroberi di daerah tersebut.

Abstract

Penelitian ini dilaksanakan pada PT. X yang bergerak pada bidang industri pertambangan dan penjualan batubara. Tujuan dari penelitian ini adalah untuk mengetahui proses pengolahan air limbah, dosis dan efektivitas penggunaan Alumunium Sulfat untuk menurunkan kadar Total Suspended Solid (TSS) serta biaya yang harus dikeluarkan perusahaan dari penggunaan Alumunium Sulfat pada pengolahan air limbah tersebut. Metode yang digunakan dalam penelitian ini adalah metode survei, dan pendekatan yang dilakukan dalam menganalisa data-data yang didapatkan adalah dengan menggunakan metode deskriptif-kualitatif. Selain hasil pengukuran dan pengamatan dilapangan, data primer lainnya didapatkan dengan melakukan wawancara secara mendalam(indepth interview) pada responden yang dinilai dapat menjadi sumber informasi yang baik. Hasil dari penelitian ini disimpulkan bahwa sumber air limbah penambangan batu bara merupakan run-off di areal Pit B yang berasal dari mata air yang berada di sekeliling dinding Pit B (area tambang) dan air limpasan hujan yang bercampur dengan lapisan over burden (OB) pada saat dilakukan kegiatan penambangan batu bara. Pengolahan air limbah kegiatan penambangan batu bara yang ditujukan untuk mengurangi kadar TSS pada air limbah tambang, dilakukan dengan teknologi pengolahan aktif. Efektivitas penggunaan Aluminium Sulfat (tawas) untuk menurunkan kadar konsentrasi parameter TSS dengan dosis yang telah ditentukan PT. X adalah sebesar 86,74 %.

Abstract

This article explains about sciences, technology its relation to moral values. The existence of sciences and technology seems to be more beneficial for human beings in implementing their activities in their daily life. It is suffice to say that sciences and technology can reduce human involvement in doing something. It can help mankind from working hard. On the one other hand, some people say that sciences and technology will be dangerous for human beings, for examples, nuclear weapons, chemical weapons, tanks, scud, and other sophisticated guns or weapons which are produced by mankind exclusively for massacring and killing enemies----human beings. Therefore, sciences and technology must be controlled by those who have moral values and religious teachings. Those who are behind the sophisticated technology should be inculcated moral values into their heart and mind. Actually, Islam is not against development and modern technology but it supports and facilitates them as long as it is beneficial for human beings. We do not have to put a blame on sciences and technology for the Muslims scholars and Muslims scientists themselves had given sAl-Ghazali, Ibnu Sina, Ibnu Rusyd, Ibnu Khaldun, Al-Tabari, Al-Kindi, Al-Jabeer, Al-Khawarizmi, Ibnu Badjah, Baiquni, Al-Farabi, Al-Razi, Omar Khayam, dan Al-Mas’udi toward modern sciences and particularly to the West (Andalusia). They had been contributing sciences and knowledge to the people both in the East and in the West which were introduced by the kingdom of Bani Abbasiyah and Bani Umayyah. Historically, Islam had been contributing sciences and technology to the Europe for more than five centuries. Unfortunately, when non-Muslims conquered Muslims countries they gave two choices for Muslims---becoming Christians or killed! Most of them were killed and some of them escaped to North Africa and Middle East. All muslims schools and libraries were burned by the conquerors. This was the worst circumstances faced by Muslims in Andalus (Spain), Bosnia Herzegovina, Kossovo, Myanmar and Iraq.

Abstract

HAPS (High Altitude Platform Station) is an airship or aircraft positioned 17-22 km altitude, or in stratosphere. HAPS is the development infrastructure of telecommunication network as BTS/BS replacement. BTS / BS is seen still has shortcomings in funding and capacity range. HAPS position is on the air layer will effected by wind disgusting so that position of HAPS will change form its normal state called Platform Displacement. Therefore, in this research, we will discuss the impact of HAPS displacement on the quality of service perceived MS (Mobile Station) by measuring the throughput. Throughput values will be mesured during MS is doing handover (HO) process, user is a mobile user who is doing WiMAX VoIP communications. Users will be simulated moves with constant speed of 50 km / h, 80 km / h, 120km / h and 200 km / h. Platform will simulated in some position upward, downward, to the right and to the left. When platform moves upward, cells will increase the coverage so each cell will interfere their neighbor especially when MS is doing HO process
