Abstract

Sand mining in Indonesia with an open pit mining system in the river has been carried out for decades. In the past, the use of traditional tools such as hoes, shovels and cikrak with human power is a mining model that is widely available in rivers. However, with the increasing demand for river sand, mining using manual tools has began to be replaced by sand mining with a sand suction machine. It should be noted that initially the majority of the people in Pematang Kasih Village were farm laborers who earned income only when the harvest season arrived. The occurrence of an economic crisis in some people in the village, with limited job opportunities in Pematang Kasih Village caused them to look for alternative livelihoods in other sectors to meet their daily needs, one of which is sand mining. The purpose of this study was to determine the effect of sand mining activities on the socio-economic, physical and public health conditions in Pematang Kasih Village. This research conducted survey method and uses quantitative descriptive analysis. It is basically gave a positive impact in the form of increasing income for miners and the ease of fulfilling local sand materials at cheaper prices and short ordering times. Meanwhile, the negative impact felt by the community is mostly through the sand mining business which can result in environmental damage such as river pollution caused by the liquid waste, disturbance of health and safety of the population, air pollution in the form of dust and clean water pollution, as well as roads damaged by the sand transporting route that crosses the area around the population. Keywords: Sand Mining, Socio-Economic, Environmental Damage, Public Health

Abstract

Construction in the field can often be encountered with various problems, one of which is damage to concrete structures or non-concrete structures that can affect the weakening of a structure. Many developed countries have carried out polymer mortar development efforts. Until now, the development of polymer mortar is still ongoing to reduce the use of cement and anticipate global warming. One of them is by utilizing polymer as an adhesive substitute for cement so that a strong mortar is produced in a shorter time. This research combines 40%-55% epoxy resin and hardener, 40% fine aggregate, 5%-20% Fly Ash and 1%-5% nanosilica. The results obtained show that the initial bond setting time is 70 minutes and the final bond is 110 minutes. This result is faster than normal mortar. The more epoxy used, the longer the bonding time. For Compressive strength test maximum Theobtained were results62 MPh with a mixture of 38% epoxy and hardener, aggregate 40% fine, 20% fly ash and 2% nanosilica.

Abstract

Geodynamic studies on the Sumatra island generally use GNSS data. GNSS data processing using the differential method by using the IGS point as a tie point. This study aims to determine good IGS point in processing GNSS data for geodynamic studies on the Sumatra island. The data used are GNSS data from 3 SuGAr points and 20 IGS points in 2019 with DOY 061, 062, and 063. 211 GNSS data processing is carried out using different IGS points. The number of tie points used are 18, 19, and 20 IGS points. Determination of a good IGS point is based on the results of the standard deviation. The factors that cause the standard deviation value are the quality of the IGS point, distance, and temperature value. The processing results with 18 IGS points are better than 20 IGS points when using poor IGS points. The processing quality at the SuGAr point on the southern part of Sumatra Island (TJKG point) is the best compared to the other two SuGAr points. IGS points that are bad for geodynamic studies are XMIS and PBRI points because of the high standard deviation values for close distances. Good IGS points with low standard deviation values are COCO, DGAR, and LHAZ points. The low temperature value at the LHAZ point is thought to be the cause of the low standard deviation value.  Keywords : GNSS, Standard Deviation, Precision, IGS, Differential

Abstract

One of the constituents of concrete is sand. Good sand for concrete material is one that has a certain size, sharpness and sharpness so that it can bind to each other. South Sumatra, where every city and district is traversed by major rivers, of course has an abundant and sufficient supply of sand material to fulfill development in the South Sumatra region. One of the largest sand-producing areas in the South Sumatra region is the one from Lahat Regency. Sand from Lahat Regency comes from the Lematang River. All locations in the Regency are traversed by the Lematang River, one of which is the West Merapi District. West Merapi District is one of the suppliers of sand for the surrounding districts, including the city of Palembang. Unlike the sand from Ogan Ilir, the sand from West Merapi is more famous for its quality. For this reason, the author is interested in raising local wealth in this West Merapi District. There are 3 largest sand-producing villages in the West Merapi area, namely Kebur Village, Payo Village and Gunung Kembang Village. The author took 3 samples of sand from the three villages in order to know which village was the best. Based on the results of testing in the laboratory, it was found that the concrete product with sand from Payo village is the best, because it has a compressive strength above 260 kg/cm2. Keywords : Local materials, K-250 Quality Concrete, sand, Desa Payo, Desa Kebur, Desa Gunung Kembang.

Abstract

Regional development and national development are interrelated with each other, where the national development target in Indonesia is to create economic growth and equalize development results, including income distribution between regions. The concept of the leading sector economy explains that all economic activities that fall into two parts are basic and non-basic. The basis or superiority is an activity of a group that produces results in the form of services or goods that aim to send far out of the group's area, either regionally, within the country, or abroad. Ogan Ilir Regency is one of the areas in South Sumatra Province which has various sectors where the average economic growth rate during 2013- 2017 is 5.34% (BPS, 2018) with a growth rate, so the researcher aims to analyze the leading sectors in the regional development of Ogan Ilir Regency, it is hoped that it can provide important information about the base sector that can be the mainstay of Ogan Ilir Regency so that regional planning can be carried out in accordance with the potential development of superior commodities obtained. The method used is quantitative analysis: the rate of economic growth, LQ analysis to determine the basis and non-base leading sectors, and shiftshare analysis to identify the superior regional sectors by comparing them with larger regions (regional or national). The results obtained are that there are 7 of the 17 sectors that are the basis, and Based on the results of the ShiftShare calculation there are 4 (four) slow moving sectors, namely; 1) Agriculture, Forestry, and Fisheries; 2) Mining and Quarrying; 3) Financial and Insurance Services; and 4) Other Services. Meanwhile, 13 (thirteen) other sectors are moving progressively. Kata Kunci : Regional Development, Leading Sector, economic

Abstract

Temperatur pembakaran, kandungan senyawa kimia air laut pada proses perendaman, dan kekuatan batu pantai sebagai agregat kasar pada beton merupakan faktor-faktor yang dapat mempengaruhi kuat tekan beton. Hal ini juga mengakibatkan perubahan struktur mikro beton akibat pengaruh suhu, senyawa air garam, dan kekuatan batu pantai sebagai agregat kasar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh temperatur, curing air laut, dan agregat kasar batu pantai terhadap perubahan struktur mikro beton fc '30 MPa yang akan dianalisis menggunakan foto SEM (Scanning Electron Microscope). Penelitian ini dibagi menjadi beberapa tahapan yaitu pengujian material, pembuatan benda uji, pengujian kuat tekan dan analisis hasil pengujian. Penelitian ini menggunakan benda uji berbentuk silinder dengan 4 variasi pengujian yaitu beton water curing normal PDAM, beton normal curing air laut, beton agregat batu pantai curing air PDAM, dan beton agregat batu pantai curing air laut dengan suhu oven 100 °C, 150 °C , 200 °C selama 3 jam dan tanpa suhu oven sebagai pembanding. Dari hasil pengujian diketahui bahwa kuat tekan rata-rata beton pada umur 28 hari mengalami penurunan nilai kuat tekan setelah di oven. Sedangkan hasil analisis mikroskopis pada foto SEM menunjukkan bahwa adanya rongga pada struktur beton akibat pengaruh panas. Perendaman air laut mengakibatkan garam mengkristal di dalam rongga beton dan menutup sebagian pori-pori rongga beton, sehingga memperlambat proses pengikatan semen dan menurunkan kekuatan beton yang berpengaruh pada penurunan gaya tekan beton.

Abstract

Palembang merupakan salah satu kota di Indonesia yang memiliki sungai besar yaitu sungai Musi. Sungai Musi yang membelah kota Palembang menjadi dua bagian yaitu bagian ulu dan bagian ilir. Kehidupan masyarakat Kota Palembang sejak dahulu sangat erat dengan sungai dimana aktifitas kehidupan banyak berlangsung di sungai. Disepanjang sungai banyak terdapat permukiman-permukiman tradisional, salah satunya adalah rumah rakit. Awal mula muncul rumah rakit tidak terlepas dari sejarah politik yang ada di Kota Palembang dimana saat itu bagi orang asing yang datang ke Kota Palembang tidak boleh memiliki tempat tinggal di daratan sehingga banyak pendatang yang membangun rumah diatas sungai. Namun saat ini keberadaan rumah rakit mulai ditinggalkan seiring dengan perubahan sistem pemerintahan dimana semua orang dapat memiliki dan membangunan rumah di daratan. Karakteristik bangunan diatas sungai tentu memiliki perbedaan yang signifikan jika dibandingkan dengan bangunan yang dibangun di daratan sehingga perlu dilakukan kajian yang mendalam terhadap bangunan rumah rakit. Penelitian ini bertujuan untuk mengetahui karakteristik yang ada pada bangunan rumah rakit yang ditinjau dari sisi arsitektur, struktur, material bangunan dan sistem utilitasnya. Untuk menemukan karakteristik rumah rakit maka, dalam penelitian ini dilakukan melalui pendekatan metode penelitian kualitatif deskriptif analitik yaitu menganalisa setiap komponen bangunan rumah rakit yang ada. Hasil dari penelitian menunjukkan bahwa desain rumah rakit merupakan hasil adaftif terhadap kondisi geografis sungai Musi yang berbeda dengan bangunan di daratan.

Abstract

Stabilitas dan level penurunan pada jalan yang menggunakan timbunan di atas tanah lunak akan bergantung pada berat timbunan. Tanah yang lunak akan sulit untuk menahan beban timbunan sehingga sering terjadi penurunan level tanah. Hal ini dapat merusak struktur bangunan di atas tanah timbunan tersebut. Salah satu solusi yang dapat dilakukan adalah dengan menimbun menggunakan material ringan sehingga dapat mengurangi berat timbunan dan mengurangi  tengangan pada tanah timbunan. Hal ini akan berdampak pada penurunan tanah dan membuat tanah menjadi lebih stabil. Salah satu jenis material ringan yang sesuai persyaratan dan dapat menjadi solusi adalah dengan menggunakan beton yang telah ditambahkan foam agent.  Foam Agent sendiri merupakan zat kimia yang mengandung sufaktan yang berguna untuk membentuk gelembung udara pada permukaan sehingga dapat menurunkan tegangan permukaan suatu zat. Dengan penambahan foam agent diharapkan mampu membuat suatu beton dengan kekuatan yang baik, dan ramah lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui nilai density dan kuat tekan pada beton penambahan 0%,15%,20%,dan25% dari jumlah air. Sampel pengujian yang digunakan adalah kubus berbentuk 15cmx15cmx15 cm sebanyak 9 benda uji pada setiap variasi. Untuk mengetahui nilai density dan kuat tekan beton dilakukan pengujian selama 28 hari. Pada beton normal memiliki nilai density 2,19 kg, beton campuran 15% bernilai 1,66 kg, beton campuran 20% bernilai 1,07 kg, beton campuran 25% memiliki bernilai 0,77 kg. Nilai kuat tekan beton memiliki nilai kuat tekan pada beton normal (0%) 351,3 kg/cm2. beton campuran (15%) 65,7 kg/cm2, beton campuran (20%) 28,0 kg/cm2, beton campuran (25%) 0 kg/cm2.
