Study of the Potential Use of Clay from Muratara Regency as Subtituent Materials for API Bentonite for Drilling Mud based on API RP 13B Mud Slurry Properties Tests Azka R Antari; Machmud Hasjim; David Bahrin

Bentonite, especially Sodium (Na) Bentonite is a type of clay that is used as a basis for water-based drilling mud in the of oil and gas wells drilling throughout the world including Indonesia, bentonite used in Indonesia is still partially imported from abroad. Sodium Bentonite can be substituted with ordinary clay which is treated by beneficiation throught addition of Na2CO3. The area of Musi Rawas Utara (Muratara) Regency of South Sumatra Province contains clay reserves resulting from pyroclastic deposit which will be investigated as potential subtitutional materials of imported API Bentonite. Clay samples from 6 different locations were prepared by first looking for the best % swell of sample beneficiation combination from all over the 36 combinations through the free swell test, the results obtained that the 4% BWOC Na2CO3 combination gave the best % swell. From this, 24 samples were prepared for various measurements of mud properties using standard equipment and procedures following the API RP 13 B for water-based mud with drilling grade Na-bentonite (API Bentonite) as standard material. The test includes 7 properties which are divided into 16 measurement units namely density, rheology, filtration, solid and liquid content, sand content, pH and methylene blue capacity etc. The test results show that the Na2CO3 beneficiation is able to change ionically the characteristics of the clay, but from the aspect of the suitability of the value of each test parameter to the standard value shows that none of the samples has full compatibility, which is mean that Muratara clay technically cannot be used as a substituent material of API Bentonite.

The aim of this research was to find out the effect of substrate concentrations (COD) of vinasse and the length of fermentation time to bio-hydrogen gas production using agent fermentation of photosynthetic bacteria, Rhodobium marinum. The production of bio-hydrogen was examined by varying COD of vinasse (10,000; 20,000; 30,000; 40,000; 50,000 mg COD/L) at certain fermentation time in the third, sixth and ninth day. The highest Hydrogen gas was obtained at ninth day of fermentation (82.66±18.6 mL). The highest Hydrogen Production Rate (HPR) and COD removal rate were obtained at concentration 50,000 mg COD/L, namely 109.98 mL H2/L/d and 1437.66 mg COD/L/d, respectively. Thus it can be concluded, the concentration of substrates (COD) from vinasse and the length of fermentation time have an effect on production of bio-hydrogen gas using Rhodobium marinum

Pomegranate (Punica granatum L.) will be examined by looking at the ability between pomegranate extracts or fractions, which are more effective in lowering total blood cholesterol and triglyceride levels in mice. This study aims to determine the active pomegranate fraction that can reduce the total cholesterol levels and triglyceride in mice. The research method used was an experimental method with a Completely Randomized Design (CRD) which was divided into 6 treatment groups, and test animals divided into 6 treatment groups namely negative control given aquades, positive control fed a high-fat diet, given simvastatin, given 25 mg/grBB of pomegranate methanol fraction, given 50 mg/grBB of pomegranate methanol fraction, given 100 mg/grBB of pomegranate methanol fraction, each treatment group will be divided into 4 male mice.Based on the results of this study that the active fraction that has an effect in reducing blood cholesterol levels and mice triglycerides is the treatment given 100mg/grBB of pomegranate water methanol fraction.

Hotspot Distribution Analysis In East Kalimantan Province 2017-2019 to Support Forest and Land Fires Mitigation Nurwita Mustika Sari; Nurina Rachmita; Masita Dwi Mandini Manessa

Forest and land fires that have occurred in the territory of East Kalimantan Province have caused immediate disaster to the area from year to year and become a global concern in recent years. Hotspots that potentially cause forest and land fires can be detected using satellites such as NOAA-20. The purposes of this study are to analyze the distribution pattern of hotspots in East Kalimantan Province during 2017-2019, identify areas with the highest risk of fires caused by the high intensity of hotspot. The method used in this study is the Nearest Neighbor Analysis and Kernel Density Estimation analysis. The results showed that the distribution pattern of hotspots in East Kalimantan Province during 2017-2019 was clustered with the highest intensity of hotspots were in Berau, East Kutai and Kutai Kartanegara Districts. And from the result of the analysis, the highest number of days has a peak hotspots on September each year. Keywords: forest and land fires, hotspots, Nearest Neighbor, Kernel Density Estimation

Analysis of The Effect Of The Addition of Fly Ash and Petrsoil on The Soil Shear Strength of The Swamp Area Indrayani Indrayani .; Andi Herius; Daiyan Saputra; Al Muhammad Fadi

The existence of irrigation canals greatly supports the production of rice produced, where irrigation channels will be equipped with embankment to protect irrigation channels. Existing soil must certainly be able to withstand shear strength to withstand embankment, while the soil in the South Sumatra region, especially the swamp area has a low shear power so it cannot hold back the shear strength from the embankment. For this reason, it is necessary to research the shear strength of the soil in the swamp area by adding fly ash and petrasoil in order to get the effect of increasing the value of the soil shear strength in the swamp area. The tests consists of the seive analysis, index properties, atterberg limits, soil compaction, and shear strength testing, based on SNI and ASTM. Mixed variations consist of 5, namely: (i) soil + petrasoil; (ii) soil + 10% fly ash + petrasoil; (iii) soil + 15% fly ash + petrasoil; (iv) soil + 20% fly ash + petrasoil; (v) soil + 20% fly ash; all variations without ripening. The test results are obtained that addition of 10% fly ash + petrasoil could be increase the soil cohesion value that is 21.56 Kpa, while the variation of the addition of 20% fly ash + water was obtained the highest value of the shear angle, that is 32.31 Kpa.
