ABSTRAK Penelitian ini mengkaji dan menjawab permasalahan mengenai bagaimana pelaksanaan penyelesaian sengketa hasil pemilukada di Mahkamah Konstitusi dan bagaimana implikasi tugas dan wewenang Mahkamah Konstitusi dalam penyelesaian sengketa hasil pemilukada. Penelitian ini merupakan jenis penelitian normatif yang bersifat deskriptif. Jenis data yang digunakan adalah data sekunder yang meliputi bahan hukum primer, bahan hukum sekunder dan bahan hukum tersier. Teknik pengumpulan data yang digunakan adalah studi dokumen dengan teknik analisis isi (content analysis). Berdasarkan hasil penelitian dan pembahasan yang telah penulis paparkan pada Bab III yang mengacu pada rumusan masalah, maka penulis menyimpulkan sebagai berikut: Dalam Permohonan Pemilu Kepala Daerah Kabupaten Bengkulu Selatan hanya dimohonkan kepada MK untuk memutus pelanggaran-pelanggaran yang terjadi dalam Pemilu Kepala Daerah tetapi dalam Putusan MK Nomor 57/PHPU.D-VI/2008 tentang Perselisihan Pemilihan Umum Kepala Daerah dan Wakil Kepala Daerah (Pilkada) Kabupaten Bengkulu Selatan, disini Mahkamah Konstitusi telah memutus melebihi permohonan yang diajukan pemohon dan memutus di luar kewenangan Mahkamah Konstitusi yaitu memutus untuk dilakukannya Pemilu Kepala Daerah Ulang tanpa ikut serta pasangan calon Nomor Urut 7 (H. Dirwan Mahmud dan H. Hartawan, S.H.). Untuk penetapan dilakukannnya Pemilu Kepala Daerah Ulang yang seharusnya menjadi kewenangan KPU dan bukan merupakan kewenangan Mahkamah Konstitusi. Dalam Putusan MK Nomor 57/PHPU.D-VI/2008 tentang Perselisihan Pemilihan Umum Kepala Daerah Kabupaten Bengkulu Selatan yang memerintahkan kepada Komisi Pemilihan Umum Kabupaten Bengkulu Selatan untuk menyelenggarakan pemungutan suara ulang selambat-lambatnya satu tahun setelah putusan tersebut. Namun ternyata tidak dilaksanakan oleh KPU pada waktu yang telah di putuskan. Hal ini dikarenakan putusan Mahkamah Konstitusi bersifat floating (mengambang) yang tidak mempunyai kekuatan hukum mengikat untuk memerintahkan KPU melaksanakan Putusan tersebut. Terlebih Mahkamah Konstitusi belum mempunyai Eksekutor dalam hal pemberian sanksi bagi yang melanggar putusan tersebut.

IMPLEMENTASI LARANGAN PARKIR BAGI PENGENDARA KENDARAAN BERMOTOR DI FLYOVER KOTA PEKANBARU BERDASARKAN UNDANG UNDANG NOMOR 22 TAHUN 2009 TENTANG LALU LINTAS DAN ANGKUTAN JALAN

But in reality, in the observations of the authors of the vehicles that we encountered, both four-wheeled and two-wheeled, almost every evening until evening, vehicles were found parked on the Flyover on the Sudirman street, Tuanku Tambusai, Sukarno Hatta and HR Subrantas. While the government has clearly provided a symbol of prohibition to stop on the bridge and in the traffic law it clearly states that everyone driving a motorized vehicle on the road is obliged to comply with the stopping and parking requirements. This is dangerous because the flyover is built only for passing vehicles and the vehicle is prohibited from parking or stopping along the body of the flyover because the flyover is not prepared not for stopping vehicles. This type of research is research conducted by identifying the law on how the effectiveness of the law applies in society. The conclusion is that the implementation of the prohibition on parking for motorized vehicle riders in Pekanbaru City flyovers based on Law Number 22 of 2009 concerning Road Traffic and Transportation which results in disruption of road functions based on Law Number 22 of 2009 is less effective and maximal. This is because there are still many people who do not know about these regulations, Lack of Socialization of Law Number 22 Year 2009 from Law Enforcement Officials, Lack of firm law enforcement officials in implementing criminal sanctions, and Lack of Legal Awareness of the Community itself. Obstacles Faced in the Implementation of the Parking Prohibition for Motorized Vehicle Riders on Flyover in Pekanbaru City Based on Law Number 22 of 2009 concerning Road Traffic and Transportation are the Legal Substance, Legal Structure, Legal Culture and Facilities or Facilities and the limited facilities and infrastructure. Efforts made to overcome obstacles in the Implementation of the Parking Prohibition for Motorized Vehicle Riders at Pekanbaru City Flyovers Based on Law Number 22 of 2009 concerning Road Traffic and Transportation are that peace and traffic order is by fostering mutual assistance and assistance among the enforcement officers and the public, the public workers' office of transportation without neglecting their respective interests in the framework of increasing obedience and compliance, thus the Government's hope of improving services in traffic order in a peaceful and orderly condition in the regions can be realized. Apart from that, the implementation of traffic control, tranquility and orderliness can also be carried out by utilizing public facilities and facilities, increasing legal awareness, increasing the number of police personnel in the traffic sphere and repressive actions. Keywords: Implementation, No Parking, Flyover  Namun pada kenyataannya dalam pengamatan penulis kendaraan yang kami jumpai baik roda empat maupun roda dua, hampir setiap sore hingga malam hari ditemukan kendaraan yang parkir di Flyover yang ada dijalan Sudirman, Tuanku Tambusai, Sukarno Hatta dan HR Subrantas. Sementara pemerintah sudah dengan jelas memberikan simbol larangan untuk berhenti dijembatan tersebut serta didalam undang-undang lalu lintas tersebut dengan tegas mengatakan setiap orang yang mengemudikan kendaraan bermotor di jalan wajib mematuhi ketentuan berhenti dan parkir akan diberikan sanksi. Hal ini berbahaya karena Flyover tersebut dibangun hanya untuk kendaraan yang melintas dan kendaraan dilarang parkir atau berhenti di sepanjang badan jalan Flyover karena Flyover itu tidak disiapkan bukan untuk kendaraan yang berhenti. Jenis penelitian ini adalah penelitian yang dilakukan dengan cara mengadakan identifikasi hukum bagaimana efektivitas hukum itu berlaku dalam masyarakat. Kesimpulan adalah Implementasi Larangan Parkir Bagi Pengendara Kendaraan Bermotor Di Flyover Kota Pekanbaru Berdasarkan Undang-Undang Nomor 22 Tahun 2009 Tentang Lalu Lintas Dan Angkutan Jalan yang mengakibatkan terganggunya fungsi jalan berdasarkan Undang-Undang Nomor 22 Tahun 2009 kurang efektif dan maksimal. Hal ini dikarenakan masih banyaknya masyarakat yang tidak mengetahui peraturan tersebut, Kurangnya Sosialisasi Undang-Undang Nomor 22 Tahun 2009 dari Aparat Penegak Hukum, Kurang tegasnya Aparat penegak Hukum dalam menerapkan Sanksi Pidana, Serta Kurangnya Kesadaran Hukum Masyarakat itu sendiri. Hambatan Yang Dihadapi Dalam Implementasi Larangan Parkir Bagi Pengendara Kendaraan Bermotor Di Flyover Kota Pekanbaru Berdasarkan Undang-Undang Nomor 22 Tahun 2009 Tentang Lalu Lintas Dan Angkutan Jalan adalah Substansi Hukum, Struktur Hukum, Budaya Hukum dan Sarana atau Fasilitas dan masih terbatasnya sarana dan prasarana. Upaya yang dilakukan untuk mengatasi hambatan dalam Implementasi Larangan Parkir Bagi Pengendara Kendaraan Bermotor Di Flyover Kota Pekanbaru Berdasarkan Undang-Undang Nomor 22 Tahun 2009 Tentang Lalu Lintas Dan Angkutan Jalan adalah bahwa ketentraman dan ketertiban lalu lintas adalah dengan membina saling membantu dan menolong diantara aparat penertiban dan masyarakat, dinas perhubungan dinas pekerja umum tanpa mengabaikan kepentingan masing-masing dalam rangka peningkatan ketaatan dan kepatuhan, dengan demikian harapan Pemerintah untuk meningkatkan pelayanan dalam ketertiban lalu lintas dalam keadaan tenteram dan tertib di daerah dapat terwujud. Selain itu pelaksanaan penertiban, ketentraman dan ketertiban lalu lintas juga dapat dilakukan dengan memanfaatkan sarana dan fasilitas umum, meningkatkan kesadaran hukum, Menambah Jumlah Personil Kepolisian di lingkup lalu lintas serta Tindakan represif

Backpropagation algorithm modeling to predict the number of foreign tourist visits to indonesia via air gates

The tourism sector is a supporting sector for the Indonesian economy. One of the important actors in Indonesian tourism is foreign tourists. After the COVID-19 pandemic, the trend of foreign tourist visits to Indonesia has increased. The Central Statistics Agency (BPS) recorded that foreign tourist visits to Indonesia during 2022 reached 5.47 million. This figure has increased by 251.28% compared to the 2021 period. According to BPS, one of the gates most accessed by foreign tourists is the air gate. Based on these conditions, this research aims to predict the number of foreign tourists coming to Indonesia via air gates. The method used to predict is the backpropagation algorithm. The use of the backpropagation algorithm is able to provide prediction results with the highest level of accuracy of 91.40% for tourist visits at Ngurah Rai Airport, Bali. Furthermore, an MSE value of 0.056 was obtained. Thus, predictions using the backpropagation algorithm can be said to be good and quite accurate and can be used for prediction calculations in the following year
