Evaluasi Unit Biofilter Anaerob Sistem Instalasi Pengolahan Air Limbah (Ipal) Rumah Sakit Ibu Dan Anak (Rsia) Anugerah Bunda Khatulistiwa Kota Pontianak

Rumah sakit merupakan salah satu sarana dan prasarana yang dalam proses pengoperasiannya menghasilkan limbah. Air limbah yang dihasilkan dari rumah sakit memiliki potensi yang dapat mencemari lingkungan apabila baku mutu yang dihasilkan belum memenuhi standar yang ditetapkan. Agar baku mutu air limbah dapat tercapai, maka diperlukan suatu teknologi yang berfungsi untuk mengolah air limbah. Teknologi tersebut dikenal dengan istilah IPAL (Instalasi Pengolahan Air Limbah). Penelitian ini bertujuan untuk mengevaluasi unit IPAL khususnya unit biofilter anaerob dan memberikan rekomendasi alternatif pengolahan IPAL yang sesuai untuk mengolah air limbah yang dihasilkan dari Rumah Sakit Ibu dan Anak (RSIA) Anugerah Bunda Khatulistiwa. Pada penelitian ini dilakukan evaluasi terhadap IPAL berdasarkan aspek kinetika proses yang meliputi rasio nilai F/M, kuantitas dan keberagaman jenis bakteri pendegradasi pada unit biofilter anaerob. Berdasarkan hasil penelitian diperoleh hasil terdapat 2 genus bakteri pendegradasi yang terdapat di dalam air limbah yaitu Bacillus sp. dan Stapylococcus sp. sehingga diharuskan dilakukan penambahan konsorsium dengan keberagaman jenis bakteri yang beragam. Sistem pengolahan yang dilakukan pada IPAL RSIA Anugerah Bunda Khatulistiwa hanya menerapkan sistem pengolahan dengan biofilter anaerob yang menyebabkan air hasil olahan IPAL belum memenuhi standar baku mutu, sehingga diperlukan adanya penambahan unit proses berupa penambahan proses aerob yang dikombinasikan menjadi biofilter anaerob-aerob agar air limbah hasil olahan dapat memenuhi standar baku mutu lingkungan menurut Kepmen LH No. KEP-58/MENLH/12/1995. Kata Kunci — Bakteri, Biofilter Anaerob, IPAL, Konsorsium, Rasio F/M

Model Distribusi Perjalanan Penduduk Untuk Penentuan Koridor ‘Lrt' Di Pulau Batam

In consequence of the increasing of regional economic activities in Pulau Batam, a reliable transportation system is required. Decreasing road network performance as a result of increasing traffic volume needs a strategic planning to anticipate the worsening condition in the future. One of the solutions is by providing mass transit system which is expected to attract private car users. Therefore, determination of potential corridor of mass transit system need to be identified so that the system provide better accessibility. Trip pattern in Pulau Batam must be known by developing trip distribution model. The trip distribution model is calibrated using origin-destination (O-D) data that is based on home interview survey. The validated model will be used to forecast and simulate travel demand onto transport network. Result of model calibration process shows mean trip length difference between model and survey is equal 0.141 %. From simulation of trip assignment is obtained that potential corridor for mass transit system using LRT is Batu Ampar – Batu Aji via Muka Kuning. Passenger forecast in the year 2030 is 193,990 passenger/day (2 directions)

The Language Attitude of Border Peoples Insular Riau, West Kalimantan, East Kalimantan, North Sulawesi, and the Eastern Sunda Islands

This research aims at describing (1) the language use of border area societies (Insular Riau, West Kalimantan, East Kalimantan, North Sulawesi, and the Eastern Sunda Islands) in terms of local language (BD), Indonesian (BI), and foreign language (BA) in the domains of family, society, and occupation, (2) language activity of border area societies relating to news observation, language attention, and language constraints in mass media, (3) language attitude of border area societies towards BD, BI, and BA. The findings are as follows. First, within the family and society at large, BD is more frequently used than BI and BA. This shows that BD functions in non-formal situations. In the professional field, however, BI is more frequently used than BD. Second, people in border provinces widely observe mass media, whether printed or electronic. They also often pay attention to the language the mass media uses. Third, border societies have a positive attitude towards BD as is shown (agree/totally agree) by the answers to eight questions relating to BD. The language attitude of border societies towards BI is positive based on the answers (agree/totally agree) to seven questions concerning BI. This also means that BI is prestigious for border people, especially in formal communication. The language attitude of border societies towards BA is mixed. In as far as it is negative it implies a positive evaluation of BD and BI because people appreciate them as part of their local and national identities

Waterbath Calibrator with Nine Channels Sensor

Water bath is a laboratory equipment that contains water or special liquid that can maintain the temperature under certain conditions during the specified time interval. For this reason, calibration is needed so that the temperature in the chamber waterbath is stable or not. calibration is carried out by comparing measuring instruments and measuring materials to be calibrated to traceable standards that are traceable to national and / or International standards. Based on the results of the identification of the problems mentioned above, the author makes a waterbath calibrator entitled "Waterbath Calibrator (9 channel)" which is very practical, and easy to operate. .This calibration tool uses a K type thermocouple sensor and also the output is displayed to the character LCD to make it easier for users to retrieve data, the reason for choosing a thermocouple sensor is because the error rate is +/- 1,1C while the LM35 is +/- 1,4C. The thermocouple temperature sensor can detect the chamber temperature quite well where the biggest error is obtained with a comparator of 2%, and the lowest error is 0%

Implementasi Embedded Web Server Via Modem Berbasiskan Mikrokontroler

In this paper there has been implemented a web server which store web pages on a microcontroller chip. To create a web server which connect to internet, TCP/IP protocol must be implemented as a software in the microcontroller system which use as web server. Protocols in TCP/IP which implemented are Serial Line Internet Protocol (SLIP), Internet Protocol (IP), Transmission Control Protocol (TCP), Internet Control Message Protocol (ICMP), and Hypertext Transfer Protocol (HTTP). Microcontroller connected physically to internet with use external V90 modem, so it is necessary to develop modem hardware interface and modem driver software. The benefit of this Embedded Web Server system compares with available systems on the market is that the TCP/IP protocol located inside the microcontroller as a software, so its realization can be cheaper and more compact, because it is not necessary to use TCP/IP chip to connect the microcontroller to internet
