Abstract

This paper will describe a study to find out the shoreline changes that occurred on Cemara Besar Island along with the accretion and abrasion. Data taken from the images were obtained through google earth as a result of radiometry and geometry correction from Landsat satellites in the last of 5 years. Wind data were obtained from ECMWF (European Centre for Medium-range Weather Forecasts) interm every season for 5 years. Analysis of shoreline changes was carried out using the DSAS (Digital Shoreline Analysis SYSTEM) method and analyzed by wind and sea wave factors involved in each season. The results of the analysis obtained LRR (Linear Regration Rate) and EPR (End Point Rate) values for 5 years, the extent of changes in island land mass, the value of Hs and Ts from the results of wave forecasting using wind data. To simplify the analysis, Cemara Besar Island is divided into 9 segments based on variations in LRR values. The results show that in general Cemara Besar Island have very high accretion rate in segments A, B and E with an average of 3.61 m/year or 5 years and very high abrasion occurred in segment F with an average of -1.01 m. Abrasion occurs with the greatest speed of change in segment A with an average of 4.64 m/year and the largest accretion rate in segment F with an average of -1.21791 m/year. Analysis of oceanographic factors through Wave forecasting data shows that in the west and transition I season, the significant waves height occur with Hs 1.21 m, greater than the eastern season and transition II season with Hs 0.91 m. Dominant wind direction from north (377.50 in west season and transition I, and from east direction (67,25 degre) in east season and transition I season.  Wind-wave propagate according to wind direction and it will be deformed when entering shallow coastal waters. Then affects sediment transport which produces accretion and abrasion on the Cemara Besar Island.

Abstract

Kesadaran terkait permasalahan kemiskinan yang belum bisa ditangani sampai dengan dewasa initentu membutuhkan keterlibatan semua pihak secara bersama dan terkoordinasi, agar cita-cita kesejahteraan dapat tercapai dengan lebih dinamis. Melalui penelitianlapangan (field research) dengansifat penelitiankualitatif deskriptif (qualitative descriptive research)serta pendekatan yuridis sosiologis.Ditemukan beberapa hasil analisis, menunjukkan bahwa program kesejahteraan Rumah Zakat mencakup beberapa hal seperti; seyum juara, seyum mandiri, seyum sehat,seyum lestari, dan terakhir seyum Ramadhan. Adapun indikatoryang digunakan Rumah Zakat berfokus pada tiga hal yaitu; pendidikan, ketenagakerjaan, dan kesehatan. Adapun ciri-ciri kesejahteraan masyarakat mengacu kepada dua parameter yakni; Pemerintah dan nisab zakat.

Abstract

Pembongkaran dan pemuatan tanah merupakan salah satu kegiatan yang sangat mempengaruhi dalam kegiatan penataan lahan reklamasi. Makin cepat kegiatan pembongkaran dan pemuatan tanah maka kegiatan selanjutnya juga akan semakin cepat. Laju produksi pembongkaran tanah dipengaruhi oleh tingkat produktivitas peralatan mekanis yang digunakan. Semakin besar produktivitas alat tersebut makin cepat sasaran produksi tercapai. Diharapkan pada periode pascatambang, lahan bekas penambangan masih mempunyai kemampuan mendukung usaha pemanfaatan selanjutnya atau setidaknya kondisi tersebut harus dikembalikan mendekati kondisi sebelum dilakukan penambangan.Luas area yang akan dilakukan kegiatan reklamasi yaitu IPD Melati seluas 5,05 hektar dan OPD Melati seluas 1,61 hektar. Volume material soil yang diperlukan yaitu IPD Melati sebanyak 30.300 LCM dan OPD Melati sebanyak 9.660 LCM dengan total 9.660 LCM.Jumlah alat yang tersedia di perusahaan PT Multi Tambangjaya Utama yaitu alat gali muat sebanyak 1 unit dengan tipe Komatsu PC 200 dan alat angkut sebanyak 6 unit dengan tipe Hino 500 FM 260 JD.Hasil produktivitas perjam alat gali muat Komatsu PC 200 setiap hari selama 7 hari didapatkan 54 BCM/jam, 55,29 BCM/jam, 111,86 BCM/jam, 111,07 BCM/jam, 141,98 BCM/jam, 115,24 BCM/jam dan 139,23 BCM/jam.

Abstract

The nation's culture can be said to be a very meaningful thing because with the existence of culture, a nation has its own specialties and characteristics which can differenciate itself from others, therefore, traditions can be identified as a nation's identity from a particular nation. The awareness of indonesian people towards indonesian culture, in this generation especially the younger ones is decreasing because of the fast growing globalisation era, a lot of young Indonesians are more intrigued in foreign countries culture in comparison  to their own nation's culture, this causes might involved in multiple factors such as limited facilities to educate students about the uniqueness of indonesian culture. Based on these factors, the application of Artificial Intelligence technology in a chatbot application which is intended as a learning infrastructure about national culture is felt to increase the enthusiasm of the young generation and make it easier for them to get information and learn various things about Indonesian culture. Learning about national culture through chatbot applications with AI technology will certainly be more attractive than the application of conventional learning methods, the aspect of flexibility in terms of learning activities will of course also increase along with the use of chatbot applications, because a chatbot can be used anytime and anywhere without requiring any special skills or requirements in its use.
