Abstract

Batam sebagai daerah yang letaknya di sisi jalur perdagangan internasional paling ramai di dunia. Perannya yang demikian tersebut penting sebagai salah satu gerbang dan ujung tombak ekonomi nasional. Letak wilayahnya yang berdekatan dengan negara tetangga Malaysia dan Singapura, membuat Batam menjadi tempat yang sangat strategis untuk bidang jasa dan perdagangan. Apalagi ditunjang dengan penetapan Batam sebagai Free Trade Zone yang akan menjadi payung hukum yang kuat dan menjadi hukum positif bagi perkembangan industri di Batam. Sama halnya dengan setiap kebijakan ekonomi yang lain, penerapan FTZ di Batam memiliki konsekwensi munculnya ‘ekonomi ikutan’ yang berimplikasi positif maupun negatif. Salah satu efek FTZ ”menyeluruh” (the black shadow of FTZ) yang harus diantisipasi adalah berkembangnya bisnis gelap (illegal trading). Catatan dari media cetak dan elektronik di Kota Batam dan Provinsi Kepulauan Riau dalam beberapa tahun terakhir mengindikasikan maraknya praktek dan modus operan di “illegal business” di perairan sekitar dan di dalam kawasan FTZ/Freeport. Kasus-kasus penyeludupan barang, binatang dan uang (smuggling) dari Batam ke Singapura, transaksi BBM illegal, praktek money laundry, trafficking, illegal fishing adalah sebagian dari praktek-praktek ilegal yang terjadi. Praktek-praktek “underground economy” semacam ini memang tidak berdiri sendiri karena disinyalir melibatkan oknum petugas dan adanya ‘transaksi’ antara oknum petugas dan oknum pengusaha. Praktek semacam ini tentu saja tidak hanya merusak sistem dan regulasi yang telah berjalan namun juga sangat berpotensi merugikan negara dari sisi ekonomi. Sebagai daerah yang bertipikal sebagai perbatasan dan berdampingan secara langsung dengan dua Negara tetangga Singapura dan Malaysia, perlu dikaji seberapa besar pengaruh penerapan CAFTA di Indonesia terutama di Batam apalagi daerah ini merupakan salah satu pusat pertumbuhan ekonomi Indonesia. Apakah praktek-praktek illegal di atas memiliki kaitan dengan akan diterapkannya CAFTA di Indonesia mengingat produk-produk Cina yang terkenal murah banyak diperjualbelikan di Batam. Perlu dilakukan penelitian untuk menggali dan mengidentifikasi secara mendalam praktek-praktek ilegal apa saja yang terjadi di Batam, mengidentifikasi sektor, pola, pelaku, tempat, waktu, dan pihak-pihak berwenang yang terlibat dalam praktekpraktek ilegal di Batam, serta menghitung berapa dan apa saja potensi kerugian negara atas praktek-praktek ilegal di Batam termasuk juga kaitan dengan penerapan CAFTA di Indonesia. Studi ini tidak hanya dilakukan dengan melakukan survei ke instansi/lembaga terkait, namun juga melakukan investigasi dan konfirmasi ke lapangan kepada pihak-pihak yang terkait dengan transaksi-transaksi tersebut.

Abstract

Power source is a device that serves to supply electrical current in type of welding SMAW (Shield Metal Arc Welding), an example is DC-400 machine. The output current of machine is set using a knob on the output control panel in order to generate heat as needed welding. Along with the development, welder realized that there are limitations in the way of controlling current on the machine. Distance control that requires users to go directly to the machine caused inefficiency in work. Therefore, we need a controller for adjusting the output current from long distance. It is necessary to create "Current Control Device for DC-400 Machine Based Microcontroller and Android". This device can adjust the output current value from long distance and wireless which is a microcontroller as the central controller and android as the input source. From the results of research, the greater value of R1 in potentiometer is set, the greater welding current is generated. The average error between the welding current using the knob and remote is 4.65%.

Abstract

This research complements the shortcomings of PLTB, namely by adding a Monitoring System to the Wind Power Plant at Batam State Polytechnic. By addition of sensors, installations, and a control panel containing instruments for monitoring wind conditions, Savonius turbine rpm, and pico-generator output electrical characteristics. The method used is conventional, starting from mechanical design, program development, and installation to testing. This study's preliminary results indicate that wind at the PLTB Polibatam location is not continuous. It does not occur, even though the maximum wind speed can reach 8.9 m / s. The implementation of the savonius-type wind turbine in this study can generate electricity around 87.83 kW / week or about 0.61 kW / hour.

Abstract

The AIS (Automatic Identification System) is used for monitoring ship traffic in the Singapore Strait. The AIS system is automated tracking system that was used in ship industry. The system consists of hardware that functions as AIS data receiver and AIS decode software developed with LabVIEW programming language. The system visualizes real-time coordinates of ships (longitude and latitude) to google maps. The method of decoding from AIS data onto ship data consists of 3 stages. Firstly, AIS data with char data type is converted to decimal. Secondly, decimal data is converted to binary and mirrors binary data results. Lastly, binary grouping according to ITU Recommendation M.1371 and binary grouping conversion with MSB reading to decimal are done. Results from the AIS system are: decoded MMSI, navigation status, Rate of Turn (ROT), ship speed, ship position (Longitude and Latitude), Course over Ground (COG), True Heading (HDG), Time Stamp, RAIM flag and Radio status. The accuracy of the system is 99.61%.

Abstract

AIS (Automatic Identification System) is an automatic tracking system used by ships and vessel traffic service (VTS) for identifying ship information by electronically exchanging data with other vessels, coastal station, and satelite. AIS can be used to monitor vessels traffic on a strait channel by detecting a large number of vessels and collecting the ships information related to ship static, dynamic and voyage information such as MMSI number, navigation status, rate of turn (ROT), ship speed, ship position, course over ground (COG), ship heading (HDG), time stamp, RAIM flag and radio status at once. On this paper we try to develop an AIS system for vessel traffic monitoring purpose in the Strait of Malacca especially in the Strait of Singapore and Batam Waterways as one of the world's most congested straits used for international shipping. The method of AIS system development is divided onto 2 stage. Firstly, AIS raw data sent by ships are recorded and decoded as ships information into an application at once. Secondly, the output of AIS decode is used into web based interactive visualization application to visualize the vessels traffic. The development of AIS system has been tested by running the AIS record, decode and web visualisation and shown that the system could be applied to vessel traffic monitoring.

Abstract

Sea Water Reverse Osmosis (SWRO) di PLTGU Tanjung Uncang berfungsi untuk menyuplai air baku melalui permurnian air laut menggunakan membrane. Dalam operasinya, membrane sering mengalami fouling dan scaling yang menurunkan kinerja sistem. Penelitian ini bertujuan mengevaluasi kinerja membrane SWRO sebelum dan sesudah proses pembersihan menggunakan metode Cleanig in Place (CIP) dan pembersihan manual (pembongkaran). Evaluasi dilakukan berdasarkan data conductivity dan differential pressure dalam tiga kondisi: sebelum Cleanig in Place (CIP), sesudah Cleanig in Place (CIP), dan setelah pembersihan manual. Hasil menunjukkan bahwa Cleanig in Place (CIP) efektif mengurangi fouling ringan, namun tidak cukup untuk fouling berat seperti lumpur. Sebaliknya, pembersihan manual lebih efektif dalam mengembalikan performa membrane ke batas normal (differential pressure ≤ 1,5 bar dan conductivity ≤ 600 µS/cm), meskipun membutuhkan waktu lebih lama. Dengan mengombinasikan kedua metode ini, efisiensi operasional SWRO dapat ditingkatkan secara signifikan.

Abstract

This study aims to examine the effect of controlling strategic processes, resource management, and innovation on entrepreneurial performance and firm performance. We analyzed data from 154 entrepreneurs and company managers of the furniture industry sector using PLS-SEM to test several hypotheses. The results show a significant effect of strategic entrepreneurship control on improving resource management, innovation, and entrepreneurial performance. Strategic entrepreneurship control, which integrates strategic entrepreneurship and strategic control, can also indirectly boost firm performance. The practical implications of this research are that to address the problem of declining performance, it is necessary to improve innovation and resource management, as well as control strategic processes through the construct of strategic entrepreneurship control. This research contributes to the field of management science, particularly entrepreneurship, strategic entrepreneurship, and strategic control.
