Indonesia is an archipelago country in which the tourism sector plays a role as an economic locomotive. In 2016, Indonesia joined the World Halal Tourism Award (WHTA) and won 12 awards, three of which were won by West Sumatra. Bukittinggi is the principal city of tourism in West Sumatra. There are many halal hotels and restaurants and 190 mosques available in the city. Unfortunately, the information regarding the mosque locations is still inadequate. For this reason, this research was conducted in order to develop a web-based and mobile-based geographic information system (GIS) for places of worship information (GPWI) to make it easier for Muslim tourists to find mosques, and other tourism objects and facilities. This paper reports on the development of the GPWI. The development of the GPWI employed the waterfall method. The GPWI allowed tourists to find mosques based on specific criteria, whose output showed them the location, information, route, and local transportation available to get to the mosques as well as other tourism objects and facilities around the mosque. The GPWI was developed using Free Open Source Software (FOSS) PostgreSQL/PostGIS, PHP, JavaScript, and Basic4Android. The spatial-based database and programs that were used to develop this GPWI are the main contributions of this study. Based on the product evaluation, the GPWI successfully met the needs of Muslim tourists in finding mosques during their visits to Bukittinggi.

In general, the application of Self-Excited Induction Generator (SEIG) or Synchronous Generator (SG) on the Stand-Alone Micro Hydel Power Plant (MHPP) is equipped with Electronic Load Controller (ELC) to control generator output during variations in consumer load. One type of ELC that is cheap and rigid developed today is the ELC, which is constructed by the uncontrolled bridge rectifier with DC Chopper. Based on the operational concept, basically this type of ELC can be implemented on both SEIG and SG, but both of these generators will have a different harmonic distortion effect on the output and its load. This paper examines the differences in the effects of harmonic distortions due to ELC installation on SEIG and SG. The initial stage of this study was to design the ELC developed. Then, the harmonic distortion response due to the installation of ELC on SEIG and SG is tested, which includes harmonic distortion in: stator current, PCC voltage, and consumer load current. THD_I(Current Total Harmonic Distortion) stator current at SEIG with ELC has shown an average value smaller than the THD stator current in SG with ELC. Likewise, the THD_V (Voltage Total Harmonic Distortion) value of PCC voltage and THDI value of the current consumer load on SEIG equipped with ELC has been shown to be smaller than the THD_V value of PCC voltage and THD_I value of the current consumer load on SG equipped with ELC. The effects of harmonic distortions due to the installation of ELCs that developed in this study on SEIG is still within the permitted limits, while on the SG, the harmonic distortion reduction is needed at the generator output.

Olahraga futsal adalah olahraga dengan lapangan tertutup dan menjadi salah satu olahraga yang paling banyak diminati dari semua kalangan. Kota Padang memiliki fasilitas lapangan futsal yang cukup banyak, namun tidak semua lapangan beroperasi dengan baik disebabkan ketidaktahuan masyarakat dengan lokasi lapangan futsal. Maka dibutuhkan sistem informasi berbasis web menggunakan Google Maps API, sehingga masyarakat dapat mengakses informasi kapanpun dengan koneksi internet. Proses pembangunan aplikasi menggunakan metode waterfall yang terdiri dari tahap analisis, perancangan, implementasi, dan pengujian. Teknik pengumpulan data dengan cara wawancara dan pengambilan titik menggunakan aplikasi Latitude Longitude Coordinates pada smartphone. Data akan dibagi menjadi data spasial dan atribut untuk memenuhi kebutuhan fungsional dari sistem yang akan dibangun.Perancangan sistem dibangun dengan menggambarkan arsitektur aplikasi, rancangan tampilan aplikasi dan rancangan database. Implementasi menggunakan basis data PostgreSQL dan ekstensi PostGIS untuk pengolahan data spasial. Bahasa pemograman yang digunakan untuk membangun aplikasi yaitu PHP, Javascript, dan HTML. Pengujian aplikasi menggunakan metode blackbox. Hasil dari pengujian menunjukkan bahwa aplikasi telah memenuhi  sembilan fungsional yang dibutuhkan dan sesuai dengan perancangan aplikasi.

A. Latar BelakangBimbingan belajar adalah bimbingan yang diarahkan untuk membantu para individu dalam menghadapi dan memecahkan masalah-masalah akademik dengan cara mengembangkan suasana-suasana belajar-mengajar kondusif agar terhindar dari kesulitan belajar. Saat ini, bimbel telah menjadi suatu kebutuhan pagi para siswa, khususnya bagi siswa yang akan melanjutkan studinya ke jenjang yang lebih tinggi.Kota Padang adalah ibukota Provinsi Sumatera Barat yang terletak di pantai barat pulau Sumatera dan berada antara 0° 44' 00" dan 1° 08' 35" Lintang Selatan serta antara 100° 05' 05" dan 100° 34' 09" Bujur Timur. Padang sebagai kota pendidikan, memiliki banyak lembaga bimbel. Namun, bagi masyarakat khususnya bagi para pendatang baru, merasa kesulitan dalam mendapatkan informasi tentang semua lembaga bimbel yang ada. Selama ini masyarakat hanya melakukan pencarian lokasi lembaga bimbel secara manual, seperti mencari informasi melalui teman atau kerabat dekat, media cetak, dan media internet.
