Abstract

Village community empowerment is a conscious effort from government officials both at the village and district levels, especially towards a potential that exists in the village as a form of assets/wealth owned by the village. This research is about community service in making portable stoves. The method used is descriptive qualitative research. This research was conducted in Bagelan Village, Gedong Tataan District, Pesawaran Regency. Participants in this activity are residents of Bagelan Village. The purpose of this study is to reveal knowledge about portable suitcases, and as a form of concern for areas that still lack funds or sales of LPG gas. From this research, this portable stove is very useful because in terms of its simple use and economical cost, the Pertebel stove can also overcome the scarcity of other fuels such as 3kg LPG gas.

Abstract

In general, infrastructure development requires materials from nature and one of them is natural coarse aggregate of crushed stone. The rapid development of infrastructure in Indonesia has resulted in the depletion of the natural coarse aggregate. Therefore, other efforts are needed in terms of using coarse aggregate as a construction material. So in this study the aim is to make artificial coarse aggregate made from fly ash. The results showed that this artificial coarse aggregate met the requirements of the General Specifications of Bina Marga 2010 rev 3 as a construction material, namely for an abrasion value of 40% and water absorption of 3%. In this study, 5 types of comparisons were carried out, namely, 70:30%, 60:40%, 50:50%, 40:60%, 30:70 and for the type of composition comparison 70:30% (70% fly ash:30% cement). ) the abrasion value is still below 40%, and the amount of water absorption is below 3% so that this artificial coarse aggregate still meets the standard specifications of General Highways 2010 rev 3. Based on the price comparison that has been made between artificial coarse aggregate and natural coarse aggregate of crushed stone , shows a price disparity of Rp. 35,779 - Rp. 58,779. Thus, this artificial coarse aggregate is one solution that can be developed to reduce the environmental impact due to the presence of fly ash which is quite abundant in Indonesia.

Abstract

Dalam penelitian ini kita menganalisa quarry yang merupakan lokasi penambangan batuan yang menghasilkan berbagai jenis ukuran material batu untuk digunakan pada pekerjaan berbagai jenis pekerjaan konstruksi seperti dermaga, gedung, jalan, drainase, jembatan dan lain-lain dan metode penambangan batuan pada penelitian ini menggunakan alat berat untuk menggali bahan batuan yang kemudian diangkut dengan menggunakan truk dan selanjutnya ke lokasi penimbangan sebelum di bawa ke stone crusher untuk di pecah menjadi jenis batuan sesuai dengan kebutuhan. Kota Bandar Lampung adalah Ibukota Propinsi Lampung yang mempunyai luas wilayah daratan Kota Bandar Lampung seluas 169,21 km² yang terbagi ke dalam 20 Kecamatan dan 126 Kelurahan dengan populasi penduduk 1.166.066 jiwa (sensus penduduk 2020). Dalam pelaksanaan kontruksi di Kota Bandar Lampung material batu sangatlah memegang peranan penting dalam berbagai jenis konstruksi seperti pekerjaan jalan, gedung dan drainase dan berbagai kegiatan konstruksi lainnya. Penggunaan material batu pada proyek pemerintah di jalan untuk bahan pencampuran perkerasan jalan berkisar 70 %, penggunaan material batu di bangunan gedung seperti pekerjaan pondasi, pekerjaan pengecoran plat lantai, kolom, sloof dan ring balok sebesar 50%. Dan pada pekerjaan drainase atau talud 85 % penggunaan material terbesar ada batu. Dari uraian di atas maka perlu dilakukan analisa kebutuhan Quarry material Batu terhadap proyek pemerintah kota Bandar Lampung pada pekerjaan jalan, gedung dan drainase dengan lokasi penelitan di salah satu Quarry yang ada di Kota Bandar Lampung. Tujuan dilakukannya penelitan ini adalah Mengetahui bagaimana kondisi eksisting pengelolaan salah satu quarry yang ada di Kota Bandar Lampung terkait kemampuan produksi untuk melayani kebutuhan Proyek Jalan, Gedung dan Drainase di Kota Bandar Lampung, bagaimana jenis perkerasan jalan yang digunakan pada proyek Kota Bandar Lampung Tahun Anggaran 2018, 2019, 2020, 2021, berapa kebutuhan material batu yang dibutuhkan untuk proyek jalan, gedung dan drainase di kota Bandar Lampung Tahun Anggaran 2018, 2019, 2020, 2021, mengetahui Benefit Cost Ratio atau B/C Ratio quarry.
