Abstract

Penelitian ini dilakukan menggunakan material baja dengan kadar karbon 0,2%. Penambahan material yang lebih keras menggunakan proses MMAW dengan elektroda HV 450. Spesimen dalam penelitian ini dilakukan pemanasan sampai dengan 1000°C kemudian ditahan dengan variasi waktu selama 10, 20, atau 30 menit. Kemudian dicelup dengan dua jenis media quenching yaitu coolant dan oli. Hasil penelitian ini menunjukan pada penahanan waktu 20 menit menghasilkan kekerasan yang lebih tinggi pada semua spesimen yang diuji. Struktur mikro yang terbentuk pada substrat adalah ferrite, pearlite dan bainit. Sedangkan struktur mikro yang terbentuk pada lapisan non treatment adalah pearlite dan bainit, sedangkan pada lapisan yang dilakukan quenching coolant dan oli adalah ferrite, bainit dan martensit.

Abstract

The 1945 Constitution states that education is a right for every citizen. Education is a conscious and planned effort to realize the atmosphere of learning and the learning process so that students can develop their potential. Education in Indonesia aims to educate the nation's life. Indonesia's education system in its development continues to make changes. The zoning policy in education is one form of positive response from the government to equalize education in each region. The zoning policy requires each student to go to school the closest distance from their residence. Schools provide about 90% of the student capacity measured by distance. The zoning policy in its development still leaves various problems. A common problem is the unavailability of educational facilities in a sub-district area so that some students have the potential to not go to school. Bekasi City is a metropolitan city that serves as a buffer for the capital city. In its development, Bekasi City has the potential to experience problems of inequality in the number of students and absorption in schools. This study aims to project the number of students and their absorption at various levels of education in Bekasi until 2025.

Abstract

Indonesia tries to protect sea areas to avoid illegal fishing cases and maritime boundary disputes. Illegal fishing that occurred in Natuna resulted in decreased income from the fishery side due to the existence of illegal fishing practices. Various attempts have been made by the Indonesian government to deal with illegal fishing by foreign fishermen and local fishermen. The case of illegal fishing that occurred at the end of 2019 was carried out by the Chinese state in Natuna waters which had triggered tension between Indonesia and China, which was triggered by different perceptions related to maritime boundaries where China used the nine-dash line concept that was not by UNCLOS recognized by the UN. This study aims to explain the nine-dash line concept that underlies unilateral claims to China, and the concept of UNCLOS which underlies ownership of the Natuna waters by Indonesia and efforts to enforce illegal fishing in the Natuna Islands. The study was conducted descriptively based on secondary data based on Indonesia's sovereign rights over the Natuna Islands. The results show that China's claim to Natuna based on the nine-dash lines does not form the basis of applicable international law

Abstract

Kesenjangan pada jumlah sampah yang dihasilkan tersebut dikarenakan oleh penanganan sampah yang umum dilakukan secara konvensional menggunakan cara pembuangan di tempat terbuka. Penyebabnya adalah terbatasnya sarana pengumpulan dan pengangkutan sampah. Hal ini akan mengakibatkan sisa atau sampah yang dihasilkan semakin banyak. Metode yang digunakan pada penelitian ini adalah metode Interpretative Structural Modelling (ISM). Metode ISM merupakan metode yang bisa membuktikan keterkaitan antar elemen yang ada. Metode ini bisa dikembangkan untuk merencanakan kebijakan strategis pengelolaan sampah. Strategi pengelolaan sampah di Kabupaten Bekasi dilaksanakan berdasarkan tingkat kepentingan dari suatu permasalahan. Dalam penelitian ini strategi utama yang perlu dilakukan yakni meningkatkan sumberdaya manusia, meningkatkan kesadaran masyarakat terkait pengelolaan sampah, teknologi pengelolaan sampah dilakukan secara efektif dan efisien serta menghasilkan energi terbarukan.

Abstract

Filsafat ilmu terdapat tiga cabang utama yaitu ontologi, epistemologi dan aksiologi. aksiologi adalah teori nilai yang berkaitan dengan kegunaan dari pengetahuan yang diperoleh. Dalam ilmu pendidikan hal ini sangat dibutuhkan dalam pembelajaran geografi, terdapat media pembelajaran yang mampu memberikan ruang dalam pembelajaran geografi, yaitu aplikasi tour builder. Penelitian ini menggunakan metode penelitian kualitatif deskriptif dengan analisis berbagai sumber baik itu dari artikel jurnal, buku, dan dokumen lain seperti buku teks, bibliografi, laporan hasil penelitian, jurnal, artikel internet, dan indeks dokumen dari instansi terkait yang berkaitan dengan topik pemanfaatan aplikasi tour builder. Tour builder dapat memberikan alternative pilihan media pembelajaran bagi guru untuk mengimplementasikan model pembelajaran dengan materi dan konten yang sesuai.

Abstract

Geografi adalah studi tentang geosfer bumi, yang terdiri dari lapisan-lapisan seperti atmosfer, hidrosfer, biosfer, litosfer, dan antrosfer. Kelima tingkatan di atas masing-masing mengkaji dan membahas pengertian, jenis, metode, pembagian berdasarkan faktor, struktur, unsur, kaidah, proposisi, dan penerapan tertentu. Tujuan epistemologi adalah untuk menemukan solusi sistematis, empiris, dan dapat diverifikasi untuk pertanyaan tentang asal usul alam semesta. Literatur ini mencoba menjelaskan komponen epistemologi geografi dengan meninjau beberapa dokumen yang menerapkan metodologi kuantitatif dan kualitatif. Karena itu sangat disarankan untuk menggabungkan kedua pendekatan tersebut dalam kajian fisika dan humaniora agar hasil penelitian geografi lebih menyeluruh. Metode keruangan (spasial), pendekatan lingkungan (ekologis), dan pendekatan kompleks wilayah (ekosistem). semuanya dapat digunakan dalam analisis epistemologis saat mempelajari geografi.

Abstract Varied physical conditions make Bogor Regency have a high disaster potential. Its hilly morphology makes it an area prone to landslides. Indonesia's Disaster Data and Information in the last 10 years (2008-2018) recorded that there had been 189 landslides in Bogor Regency. The local BPBD has mapped areas prone to landslides and found that areas on the east side of Bogor Regency are more vulnerable than those on the west side. Sukamakmur District, which is located on the east side of Bogor Regency, is also a landslide-prone area. Sukamakmur, Pabuaran and Wargajaya villages are the most prone to landslides in Sukamakmur District. Meanwhile, Sukawangi Village is the area with the most frequent landslide records in the last 4 years. The activity of strengthening the capacity of youth organizations in dealing with disasters is considered a pioneer in disaster-prone areas designed to become disaster-resistant areas. The results of the data collection state that most youth organizations in Sukamakmur Regency have not focused on disasters. This is caused by several obstacles, considering that the area is an area with a high level of disaster vulnerability, a strategy for strengthening the capacity of youth organizations is needed in dealing with disasters. Abstract Kondisi alam fisik yang bervariasi menjadikan Kabupaten Bogor memiliki potensi kebencanaan yang tinggi. Morfologinya yang merupakan perbukitan membuatnya menjadi daerah rawan longsor. Data dan Informasi Bencana Indonesia dalam 10 tahun terakhir (2008-2018) mencatat telah terjadi 189 kejadian bencana tanah longsor di Kabupaten Bogor. BPBD setempat telah melakukan pemetaan daerah-daerah yang rawan akan bencana longsor dan menemukan bahwa wilayah yang berada di sisi timur Kabupaten Bogor lebih luas kerentanannya dibandingkan yang berada di sisi barat. Kecamatan Sukamakmur yang letaknya di sisi timur Kabupaten Bogor tidak luput menjadi daerah rentan longsor. Desa Sukamakmur, Pabuaran dan Wargajaya merupakan yang paling rawan longsor di Kecamatan Sukamakmur. Sementara itu Desa Sukawangi merupakan daerah dengan catatan bencana longsor tersering selama 4 tahun terakhir. Kegiatan penguatan kapasitas karang taruna dalam menghadapi bencana dinilai bisa menjadi pioner untuk sebuah wilayah yang rawan bencana di design menjadi daerah tangguh bencana. Hasil perolehan data menyebutkan bahwa mayoritas karang taruna di Kecamatan Sukamakmur belum terfokus pada kebencanaan. Hal ini disebabkan oleh beberapa kendala, mengingat wilayah tersebut merupakan daerah dengan tingkat rawan bencana yang tinggi maka diperlukan sedangkan strategi terhadap penguatan kapasitas karang taruna dalam menghadapi bencana
