Organic Geochemical Characteristic Of Crude Oils From Orange Graben, South Sumatra Basin

Lemat Formation in the Orange Graben in the South Sumatra basin has been considered as syn-rift sediments consist of fluvio-lacustrine sediments, create source rock with fluvio-lacustrine characterize. Based on existing publications, showing that the oils from Orange Graben have fluvio-deltaic characterization and generated by source rock from Talangakar Formation with fluvio-deltaic depositional environment. This paper emphasizes geochemistry methods. Source rock analysis, consist of 26 samples for carbon isotope and 14 samples for biomarker, while oil analysis, consist of 15 samples for carbon isotope and 19 samples for biomarker. Characterization has been based on qualitative and quantitative data. Qualitative data comprise evaluation based on chromatograms and mass-fragmentograms, whereas quantitative data consists of a series of cross-plots, eg. cross plot of carbon isotope δ13C saturates - aromatics, distribution of C27-C28-C29 sterane, Pr/nC17-Ph/nC18, Pr/Ph-Pr/nC17, carbon isotope δ13C saturates-Pr/Ph, Pr/Ph-total hopane/total sterane, and ratio of C26/C25 (tricyclic). Based on geochemical result of analysis, source rocks of Lemat Formation in the Orange Graben interpret as source rock with fluvio-deltaic characterize, have terrestrial influence while Talangakar Formation in the Orange Graben interpreted as source rock with deltaic characterization, having marine and terrestrial influence. Both of them , consist of humic kerogen. Whereas, oil samples in the Orange Graben interpreted as oilwhich is generated by source rock with fluvio-deltaic characterization, having terrestrial influence, in anoxic-suboxic-oxic conditions, consisting of humic kerogen. Correlation result between source rocks and oils in the Orange Graben, indicating that fluvio-deltaic oil type in the Orange Graben are correlate with not only the source rocks of Talangakar Formations but also with source rock of Lemat Formation. &nbsp

Pengaruh Ukuran Butir Kapur Berbeda terhadap pH, Fe-larut dan Al-tukar Tanah pada Lahan Pasang Surut

Swampland in Indonesia covers an area of ​​34.93 million ha spread over various islands such as Sumatra, Java, Kalimantan, Sulawesi, and Papua. One type of swamp land that is often used in agriculture is tidal lands. The problems faced in the development of tidal lands for agriculture include acidic soil pH, high levels of soluble Fe and Al. One of the efforts to overcome the problem of acidic soil pH, high levels of soluble Fe and Al-dd is liming. The finer grain level of lime may increase the effectiveness of liming. The purpose of this study was to quantify the effect of lime grain sizes on changes in pH, dissolved Fe, and exchangeable Al of tidal lands. This study employed a one-factor completely randomized design (CRD) consisting of 6 treatments (Control; CaCO3 more than 1.00 mm (> 18 mesh); CaCO3 lime, 0.5-100 mm (18 -35mesh); CaCO3 measuring 0.21-0.50 mm (35-70 mesh); CaCO3 measuring 0.21 mm (<70 mesh); CaCO3 lime measuring 0.15-1.00 mm (18 -100 mesh)). The results showed that the difference in the size of the CaCO3 lime granules had a significant effect on changes in pH, soluble Fe and exchangeable Al. The application of CaCO3 lime granules 0.21 mm (<70 mesh) result in increases in soil pH and suppress soluble Fe and exchangeable Al.Swampland in Indonesia covers an area of ​​34.93 million ha spread over various islands such as Sumatra, Java, Kalimantan, Sulawesi, and Papua.

PENGARUH KONSENTRASI DAN INTERVAL WAKTU PEMBERIAN PUPUK ORGANIK CAIR AZOLLA TERHADAP PERTUMBUHAN DAN HASIL TANAMAN PAKCOY Varietas Nauli (Brassica rapa chinensis L.)

The aim of the research was to determine whether there was a real interaction effect of Azolla POC concentration and the time interval of POC administration on the yield and growth of Pakcoy plants. The research used a Randomized Group Design (RAK) arranged factorially including 2 factors which were repeated 3 times. Factor I is the nutrient dose of Azolla liquid organic fertilizer which consists of 3 levels 4 namely D1: 0 ml/1 water, D1: 2 ml/l water, D2: 4 ml/l water, D3: 6ml/l water and Factor II is Time interval for application of 3 level Azolla liquid organic fertilizer. S1: Application time interval 2 days, S2: Application time interval 4 days, S3: Application time interval 6 days. Plant height (cm) was observed at 0, 7, 14, 21, 28, 35 HST, measured using a meter. The number of leaves at 1, 3, 5, 7 and 9 WAP and leaf width at 0, 7, 14, 21, 28, 35 HST were measured using a tape measure. Accumulated fruit weight per plant (grams) The wet fruit weight of Pokcoy plants is determined by weighing all parts of the plant (roots, stems, leaves). Plants were weighed one by one using an analytical balance. Observational data were analyzed using Analysis of Variance (ANOVA) with a level of α = 0.05 and if there were significant differences between treatments then a further test was carried out using the DMRT test (Duncan's Multiple Range Test) at a level of α = 0.05. The results of research that have been carried out have concluded that there is a real interaction between the concentration of Azolla liquid organic fertilizer (D) and the time interval for POC application on the growth and yield of Pak Choy plants. The best treatment combination for plant height variables; number of leaves; leaf area is the D2S2 treatment, namely the combination treatment of azolla POC concentration of 4 ml/L and the POC application time interval of 4 days, while for plant fresh weight the best combination is D2S3, namely the combination treatment of 6 ml Azolla POC concentration and 4 day POC application time interval with weight. fresh plants amounting to 58.17 grams

Risk Analysis of Combustion Failure in Gas Turbine Start Process in PLTGU Unit PT.X

The peaker power plant is a power plant that is operated when the network is at peak load. Being a peaker power plant has an impact more often start- stop for operation of gas turbine. So, the readiness of the gas turbine to start any time is the core business of the peaker power plant. But in reality, start failure still occurs in the generating unit. Start failure can be caused by combustion failure. In 2017 and 2018 years, there was a start failure caused by combustion system failure total 10 out of 19 cases internal start failure. A lot of disadvantages of start failure for the company like very much loss of potential production revenue, loss of fuel consumption, electricity usage for supporting equipment, materials of gas turbine, failure to achieve KPI’s company, decrease in customer satisfaction and much more. So, it must be minimized or eliminated. Until now, maintenance for start failure still corrective maintenance. Corrective maintenance is an unscheduled, unpredictable, unplanned or unprogrammed maintenance action based on an event at a certain time so the potential loss of company’s income large. One effort to reduce corrective maintenance activities with preventive maintenance. However, to do preventive maintenance, it is necessary to conduct in-depth studies and analysis so that preventive maintenance is carried out effectively and on target. For this reason a risk analysis of the combustion failure with Failure Mode and Effects Analysis (FMEA) method need to do, so the preventive maintenance steps can be obtained to mitigate the risk of start failure in gas turbine power plant. From the result of FMEA, there are two extreme risk from combustor system, igniter and fuel valves. So, preventive maintenance applied to them. It can provide a large potential revenue for industry and company reputatio
