Abstract

Surfactant which is used as raw emulsifier in an industry activity such as Sodium Lauryl Sulfonate is a raw material import, it is petroleum derivative which is not renewable and may cause pollution to the environment, because it is not degraded and are carcinogenic. The purpose of the research is to compare the characteristics of the Quaternary methyl ester sulfonat (MES) and Sodium Lauryl Sulfonat (SLS) as emulsifier. First, make the MES by filtering and eliminating fatty acids of palm oil, then process the MES with enzymatic method become methyl ester, then react it in sulfonation and metanolization process, and also neutralized with NaOH. Next, the MES experiment is compared with SLS and existing MES in the market. The results show that surfactants MES experiment has value hidrofil lipofil balance (HLB) interfacial tension and emulsion stability greater than MES in the market and SLS. And the surface tension of MES experiment is larger than MES in the market, but smaller compared to SLS.ABSTRAKSurfaktan yang digunakan sebagai bahan baku emulsifer dalam aktivitas suatu industri pada saat ini seperti Sodium Lauril Sulfonat  merupakan bahan baku import yang merupakan turunan dari minyak bumi, dengan sifat tidak dapat diperbaharui dan dapat menimbulkan pencemaran terhadap lingkungan karena tidak mudah terdegradasi serta bersifat karsinogenik. Metil ester sulfonat dari bahan minyak sawit merupakan surfaktan dengan sifat mudah terdegradasi yang perlu diketahui karakteristiknya. Penelitian bertujuan untuk membandingkan karakteristik surfaktan metil ester sulfonat (MES) dan Sodium Lauril Sulfonat (SLS) sebagai bahan emulsifier. Mula-mula dilakukan pembuatan MES dengan cara menyaring dan menghilangkan asam lemak minyak sawit terlebih dahulu, kemudian diolah menjadi metil ester secara enzimatis, lalu direaksikan secara sulfonasi dan metanolisis, serta dinetralkan dengan NaOH. Selanjutnya MES hasil percobaan dibandingkan dengan SLS dan MES yang ada dipasaran. Hasil penelitian menunjukkan bahwa surfaktan MES memiliki nilai hidrofil lipofil balance (HLB) tegangan antar muka dan stabilitas emulsi lebih besar apabila dibandingkan dengan MES di pasaran dan SLS, kecuali nilai stabilitas emulsi antara MES dan SLS sama. Dan tegangan permukaan MES hasil percobaan, lebih besar dibandingkan dengan MES dipasaran, dan lebih kecil dibandingkan dengan SLS. Kata kunci :   Metil  ester sulfonat, hidrofil lipofil balance, emulsifier, sodium lauril sulfonat , stabilitas emulsi

Abstract

A landslide is an event where a mass of rock, soil or a mixture of rock and soil are moved as a slope. One of the mechanical properties that can be a trigger of landslides is the reduction in rock shear strength. In this research, the authors used the Geophysical method that is Ground Penetrating Radar (GPR), by utilizing different dielectric properties of rocks when given electromagnetic wave propagation to see the amplitude contrast in the recorded data as an approach to the type of rock lithology and rock layers below the soil surface so that it can be used to identify layers that cause landslides. The frequency of GPR that used in this research is 40 MHz. The research aims to determine the type of layer that causes landslides in the area of ​​Sangatta Aircraft Monument, PT. Kaltim Prima Coal. The results of this research are in the form of GPR data which is correlated with the carrying capacity of the soil so that the avalanche causing layer in the study area is sandy clay layer.

ABSTRACT The research has been conducted on the analysis of electromagnetic field radiation caused by mobile phones. Based on battery power differences. The measurements were made on July 25, 2019, July 26, 2019, July 27, 2019 at the Instrumentation Laboratory at the Faculty of Mathematics and Natural Sciences, Molwarman University, from 8:00 to 16:00. The measurement method used is frequent measurements using the QX-5 electromagnetic field tester on each type of mobile phone, which is already identified. The results showed that the radiation intensity in the three mobile phone brands had radiation intensity values lower than the threshold value of 10 MW / cm 2. From data analysis, it was found that the mobile phone with the highest electromagnetic radiation intensity was the Samsung J2 Prime mobile phone while The smallest phone Vivo Pro 15 Vivo mobile. Mobile phone battery that has the highest value of electromagnetic wave intensity in weak battery power is 25% < DB ≤ 50%, the mobile phone use distance that has the highest electromagnetic radiation intensity is at a distance of 0 cm and 3 cm and a good distance in the use of mobile phone It is 6 cm, 9 cm, 12 cm, the greatest intensity of electromagnetic wave radiation during use or making a phone call whatsapp.

Abstract

Geoelectric Resistivity is one of the geophysical methods that utilize different electrical properties in the earth in the form of resistance type in rocks. In this research, was measurements on Kadrie Oening Street at Pulau Balang formation and measurement of laboratory scale resistivity at Electronic and Instrumentation Laboratory. From the field measurements, three configurations are used: Wenner Alpha, Dipole-Dipole and Pole-Dipole. From the three configurations, sandstone resistivity value between 11.93 W.m to 33.61 W.m, clay ranged between 3.86 W.m to 10.82 W.m, siltstone range between 4.80 W.m to 9.72 W.m, coal ranged between 83.88 W.m to 216.47 W.m. The resistivity data inversion shows that the Wenner Alpha and Dipole-Dipole configurations are more compatible with field conditions in displaying the slope of the coating than the Pole-Dipole configuration.

Abstract

Pada penelitian ini dilakukan interpretasi karakteristik batubara di konsensi tambang Separi 3, Tenggarong Sebrang, Kabupaten Kutai Kartanegara. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik batubara bedasarkan data Geophysical Logging di area pertambangan PT. Mitra Abadi Mahakam. Terdapat berbagai metode untuk melakukan interpretasi karakteristik batubara. Dalam penelitian ini digunakan metode Geophysical Logging khususnya dengan respon Gamma Ray untuk mengetahui karakteristik batubara dari 3 titik lubang bor. Membandingkan data pemboran dengan data logging dengan cara melihat litologi dari kedua hasil data tersebut. Berdasarkan perbandingan data logging dan data log litologi dari inti bor, maka data log GR memiliki karakteristik akurasi kedalaman yang lebih baik dikarenakan kemenerusan pengambilan data, tidak seperti inti bor yang diambil setiap interval kedalaman 3 m. Dari pengolahan data diperoleh karakterisasi sifat fisik batubara secara keseluruhan, yaitu hitam, mengkilap, kompak, rapuh dengan ketebalan yaitu seam 1 dan 2 pada CC-29 dengan rata – rata ketebalan 4 dan 5 meter dengan range nilai Gamma Ray berkisar 0 – 36 API dan 12 – 58 API, seam 1 pada CC-2035R dengan rata – rata ketebalan 2 meter dengan range nilai Gamma Ray berkisar 0 – 52 API, seam 1 dan 2 pada CC-29 dengan rata – rata ketebalan 4 dan 2 meter dengan range nilai Gamma Ray berkisar 0 – 30 API. Lapisan batubara nya ditinjau dari karakteristik lingkungan pengendapan sangat berpengaruh terhadap pergerakan grafik gamma ray. Pada hasil ini karakteristik elektrofasies pada daerah penelitian yaitu cylindrical/boxcar. Daerah cylindrical/boxcar umumnya terbentuk atau terendapkan pada daerah rawa.

Abstract

This research has been conducted using the Ground Penetrating Radar method to interpretation subsurface conditions that have the potential to become Subsidence on Jalan Ring Road II Samarinda. East Kalimantan, Ground Penetrating Radar Method is a geophysical method that utilizes the propagation of electromagnetic waves to identify subsurface structures, where the recorded penetration of depth and amplitude is affected by the dielectric properties of a material. This study uses an antenna with a frequency of 100 MHz. Based on the interpretation of radar data the potential for a subsidence to occur on track 1 and track 2, in this layer explains that there is a weak field that occurs due to infiltration where the entry of water flow into the soil through the surface of the ground and the condition of the road is steep so that water easily enters the area that has experienced subsidence due to fractures. On lines 3 and 4 there are several different amplitude intervals that are marked by changes in color on radar data which results in factors of material heterogeneity or water content in the layer.
