Optimal production of ammonia (NH3) using natural gas is necessary in order to make it available for wide range of applications including the manufacture of fertilizers, fuel for transportation and during synthesis of some chemicals. Achieving this would require strategic implementation of a control scheme to simulated ammonia production, capable of ensuring adequate realization of production targets. The work involves ASPEN Plus modeling, simulation, sensitivity analysis and control of NH3 production process. Steam/carbon ratio, conversion of CH4, removal of carbon dioxide (CO2) and carbon monoxide (CO), hydrogen/nitrogen ratio and heat exchanger and separator temperatures were identified as requiring control in units any of these specifically impacts. As a result, approximately 176 tons of NH3 was realized daily based on the simulation results and can be scaled-up using a calculated factor equivalent to 1.1375 to 200 tons/day capacity, in this design. Sensitivity analysis resulting in control of certain unit parameters is effective in ensuring process safety, maximum yield of important end-products and reduction in the cost of operation

This study investigates the corrosion rate and corrosion behavior of carbon steel pipe at constant condensed fluid from a geothermal power plant. The corrosion rate of the steel was determined by weight loss analysis, whereas the corrosivity of the condensate fluids was measured by a multimeter Hach HQ40d. The morphology of the corrosion products formed was characterized by scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and x-ray diffraction (XRD) analysis. Results showed that the corrosion rate in the liquid part of the condensate fluids is constant during the immersion period when water quality parameters are constant. Meanwhile, the corrosion rate of low carbon steel pipe decreases though with the longer exposure period in the condensate fluid. The decrease of metal corrodibility identical to the lower corrosion rate at a longer exposure time due to the protective corrosion layer formed. The corrosion products during immersion tests identified in the corrosion test were uniform with iron oxide in the form of FeO(OH) and Fe2O3*H2O.

Zakat fitrah is a zakat that must be issued by every individual who is Muslim whose time is related to the holy month of Ramadan. The purpose of zakat fitrah is to purify the soul and fulfill the needs of the needy and poor people on Eid al-Fitr. For the determination of mustahiq must be exactly as specified in Islamic law so that the purpose of zakat fitrah implemented.The practice of managing zakat fitrah in Ngadirojo Village, Sooko District, Ponorogo Regency is left to each mosque in the village. The distribution is carried out by distributing zakat fitrah to people in need and orphanages. But there are still mosques where the distribution of zakat fitrah is distributed evenly by the zakat committee to local residents without looking and considering the economic situation as a mustahiq. In the village there is also one mosque that utilizes zakat fitrah for khataman activities at the end of Ramadan. Why is zakat fitrah in one mosque in Ngadirojo village distributed evenly to local residents without looking at the poor or rich and why does zakat fitrah be used for religious activities? then how about a review of Islamic Law on these practices? This type of research conducted in this study is field research, namely data obtained from direct searches regarding the management of zakat fitrah in Ngadirojo Village, Sooko District, Ponororgo Regency. In getting the data, the compiler made observations and interviews directly to Mudin (zakat fitrah manager in Ngadirojo Village), zakat fitrah committee, and local residents. While the approach that the authors did in this study uses a normative approach, which is to solve the problem using the Qur'an, the hadith, and opinions of the scholars. In analyzing the constituent data using qualitative analysis by analyzing all data collected then described by the inductive method.The practice of the distribution of zakat fitrah in some mosques in Ngadirojo Village distributed to people in need and orphanages is in accordance with Islamic Law. But the distribution of zakat fitrah which is distributed evenly and the use of zakat fitrah for khataman events at the Ar-Rohmah Mosque, Hamlet Wates, Ngadirojo Village cannot be justified in Islamic Law because it does not match what is stated in the Koran at-Taubah verse 60 and not in accordance with the Prophet's hadith.

P enelitian ini bertujuan untuk mempelajari korosi pada baja galvanis setelah diekspos di Sungai Cidaho Wilayah Sukabumi, Jawa Barat.

Mitigation and control of bacterial corrosion must have been prioritized for failure anticipation by corrosion associated with microorganisms. Using synthetic inhibitor for material protection from corrosion have problems because it is not eco-friendly. This work conducted preliminary studies on T. cordifolia stem extracts at various methanol ratios against P. aeruginosa biofilm as a new eco-friendly inhibitor. The T. cordifolia stem was extracted by the maceration method with a different ratio of methanol solvent (100, 75 and 50 %). The bacterial activity was assessed using the dilution method (MTT assay) to determine the minimum inhibitory concentration (MIC). The total phenolic and flavonoid contents were determined using Follin-Ciocalteu and aluminum chloride (AlCl3) colorimetric, respectively. Meanwhile, the structure of the active compounds in the extract was identified by using the liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). The yields of T. cordifolia extracts are 9.45, 7.56 and 8.40 % at 100, 75 and 50 % of methanol ratios, respectively. The total phenolic content (TPC) in crude methanol extract of T. cordifolia is 11.20, 9.46 and 6.56 % for 100, 75 and 50 % of methanol ratios. Meanwhile, the flavonoid content (TFC) was obtained is about 5.25, 0.64 and 0.33 % for 100, 75 and 50 % of methanol concentrations, respectively. The T. cordifolia extract has antibacterial activity against P. aeruginosa in all ratios of methanol concentrations. The minimum inhibitory concentration (MIC) of T. cordifolia methanol extract was found at 4096 µg/mL. Methanol solvent concentration with the most active antibacterial activity of the extract was 50 %, followed by 75 and 100 %. The structures of the active compound in the methanolic extract of T. cordifolia are a phenolic group, and it is in the alkaloid derivatives (Calopiptin, d-Lirioferine (Lirioferine), Moupinamide, Piperanine, and Yuanhunine). HIGHLIGHTS The crude methanol extract of Tinospora cordifolia stem has potential against aeruginosa in the marine environment The minimum inhibitory concentration (MIC) was found at 4096 µg/mL of extract in a ratio of 50:50 (v/v) of methanol to water The compound structures in cordifolia methanol extracts are Calopiptin, d-Lirioferine (Lirioferine), Moupinamide, Piperanine, and Yuanhunine GRAPHICAL ABSTRACT

The investigation of atmospheric corrosion of mild carbon steel as representative of offshore infrastructure has been carried out in the marine tropical of Pelabuhan Ratu, West Java, Indonesia. They are exposed up to 76 days of periods, and their corrosion rates are determined according to ASTM G1-03. The surface morphology, the elemental compositions and compounds were observed using a scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD), respectively. The environmental parameters of the test site are monitored during exposure, such as air temperature, relative humidity (RH), airborne salinity and dew temperature. Based on the results, the corrosion rates of steels were 2.79 and 2.8 mpy within the 27 and 76 days exposures, respectively. The presence of chloride deposition on the surface of steel can increase the severity of corrosion. Moreover, the detrimental effect of chloride was observed in rust product, which was covered by an oxygen element. The main phases of rust products present were magnetite (Fe3O4) and hematite (α-Fe2O3.H2O). Several cracks were observed in the rust layer, which tended to exfoliate and lose adherence and protectiveness from further corrosion attack. HIGHLIGHTS The presence of chloride deposition on the surface of steel can increase the severity of corrosion. The severity of corrosion attack mainly depends on the exposure time and some climatic parameters, such as relative humidity (RH), air temperature and chloride airborne. The uniform distribution of the chloride tends to increase the production of ferrous chloride in high RH condition and the aqueous layer deposited on carbon steel. There are two phases on corroded carbon steel such as hematite (α-Fe2O3.H2O) and Magnetite (Fe3O4) after exposure GRAPHICAL ABSTRACT

In this study, we presented observations and analyze related to internal corrosion in condensate pipes in geothermal power plants. A damaged pipe of condensate pipeline taken from a power plant was investigated to determine the root cause of failure. The observation and failure analysis was carried out by visual and dimensional examination, chemical composition testing, macroscopic, and microscopic examination, Scanning Electron Microscope (SEM) examination with Energy Dispersed Spectrometer (EDS). The deposit in the pipe was analyzed by X-Ray Diffraction (XRD). The quality of the condensate fluid and their tendencies were determined by Langelier Saturation Index (LSI). Also, the corrosion rate of the pipe was simulated by condensate fluid by using a corrosion measurement system (Tafel polarization). The internal corrosion was found in the condensate line is strongly suspected to occur due to erosion-corrosion. Erosion corrosion is caused by insoluble and hard particles in the condensate fluid. The results of XRD found the presence of calcium-silicate compounds in the sediment that is suspected to be the cause of erosion particles. The reduction of the thickness of the bottom pipe wall and occurs in longitudinal directions the alleged damage to the pipe due to sediment corrosion. The presence of hard compounds and differential oxygen can accelerate the process of corrosion so that the corrosion rate in condensate pipelines was a category in the severe category based on NACE SP0775 standards.

Pendidikan Islam, sebelumnya hanya dipersepsi sebagai materi ajar, sekarang telah dipersepsi sebagai materi,sebagai institusi, sebagai kultur, dan sebagai system. Inilah yang sekarang tercermin dalam undang-undang nomor 20 tahun 2003 tentang sistem pendidikan nasional dan peraturan pemerintah secara operasional mengatur pelaksanaan undang-undang tersebut. Dengan demikian, maka peneyebutan istilah “pendidikan islam” bisa mencakup empat persepsi: pertama, pendidikan islam dalam pengertian materi; kedua, pendidikan islam dalam pengertian institusi; ketiga, pendidikan islam dalam pengertian budaya dan nilai-nilai, dan keempat, pendidikan islam dalam pengertian pendidikan yang islami. Oleh karenanya dalam konteks perubahan zaman, perkembangan institusi pendidikan islam tidak sepenuhnya bisa menghindar dari perubahan, sebagiman pondok pesntren, lembaga-lembaga islam juga mneganut prinsip “continuity and change” atau dalam bahasa pesantrennya disebut“ al-muhaadhah alal qadim ash-shalih wal akhdzu bil jaded al-ashlah”, intitusi pendidikan islam akan terus melakukan perubahan dan adopsi inovasi tetapi tetap mmepertahankan tradisi yang baik dan bermanfaat.

Polarization methods measure the corrosion rate in inlet water of Kujang ammonia plant at 32, 37, and 50°C. The measurement reveals that carbon steel C1045 is the most resistant to corrosion at each temperature.

ionRestorative Justice accommodates the interests of the parties, including the victim, because the victim in this case is involved in determining the sanctions for the perpetrator. Restorative Justice returns conflict to the most affected parties (victims, perpetrators and “their community”) and gives priority to their interests. Restorative justice seeks to restore the victim's safety, personal respect, dignity, and more importantly a sense of control. By adhering to the paradigm of restorative justice, it is hoped that the loss and suffering suffered by the victim and his family can be recovered and the guilt burden of the perpetrator of the crime can be reduced because he has received forgiveness from the victim or his family.

Kenaikan suhu akan menyebabkan bertambahnya kecepatan reaksi dan mengakibatkan laju korosi menjadi meningkat. Selain faktor suhu larutan, korosi di media air laut juga dipengaruhi oleh kandungan oksigen terlarut, salinitas, pH dan total padatan terlarut.

The investigation of corrosion for carbon steel and galvanized steel has been conducted in the marine atmosphere of Eretan and Ciwaringin Districts, West Java Province. The exposure time of the field test was up to 200 days, and their corrosion rates are determined according to weight loss method. The objective of the work is to elucidate the corrosion behavior of those alloys which is affected by distances from coastline and environmental condition. The magnitude of corrosion rate for carbon steel was 20 times as high as that for galvanized steel in both districts The distance from coastline has significantly affected for the magnitude of corrosion rate, where that both alloys in Ciwaringin is lower than that in Eretan. The deposition of chloride ion in Eretan and Ciwaringin Districts were 4.305 mg/m2 day and 1.863 mg/m2 day, respectively, where the higher chloride ion can tend to increase the corrosion rates. Relative humidity (RH) which is over 60% has essential role for corrosion process as well as rainfall. The uniform corrosion attack was observed both alloys after exposure. The corrosion product phases of galvanized steel exhibits as zincite, hydrozincite and simonkolleite in Eretan as the typical coastline atmosphere phases but not in Ciwaringin. The formation of rust product for both metals lead the decrease of further corrosion attack due to the barrier between metal and environment. The usage of galvanized steel is remarkable to minimize corrosion attack compared to that of carbon steel in tropical coastline.
