Abstract

This research was intended to investigate the effect of the geometry and blockage ratio of the flame connector on the combustion characteristics of wood pellets on a wood pellet stove. Combustion characteristics observed in this research included flame visualization, flame temperature, specific fuel consumption, and corrected-specific fuel consumption. Two types of geometry were used as a flame connector, i.e. disk and cone; for each geometry, the blockage ratio was varied at 0,6, 0,7, and 0,8. The blockage ratio was varied by change the number of the circular hole on the flame connector. Combustion in wood pellet stove without flame connector was then used as a comparison. The flame visualization test was applied to find out the color and dimensions of the flame, which was then used to determine the temperature on this flame. The water boiling test method version 4.2.3 was used to determine specific fuel consumption and corrected specific fuel consumption. The combustion chamber of the wood pellet stove has a dimension of 15 cm diameter and 20 cm height. Wood pellet supply used intermittent - continuous feeding system with a mass flow rate of 16 gram/minute. Flame visualization shows that stove with cone flame connector has a larger flame dimension and flame dimension decreases with the increasing of blockage ratio. The highest flame temperature occurred near the outlet of the combustion chamber, the same conditions were observed in all variations experiment.  The application of flame connector involves greater specific fuel consumption due to longer boiling time. However, a correction factor by considering the amount of evaporated water results from corrected specific fuel consumption of wood pellet stove with cone flame connector which is smaller compared to the other type of wood pellet stove.

Abstract

This aim of this research was to conduct the effect of HHO which injected into the combustion chamber through the intake manifold of the gasoline four-stroke motorcycle engine. HHO is a mixture of hydrogen and oxygen was produced by water electrolysis process.The experiments were carried out by using the HHO generatorin intake manifold to produced HHO gas, which injected into the combustion chamber. The HHO gas injection was varied of 0 ml/s, 0.75 ml/s, 1.5 ml/s, 2.25 ml/s and 3 ml/s based on the engine shaft revolution (rpm). The engine shaft revolutions were also varied at 1700 rpm, 2200 rpm, 2700 rpm, 3200 rpm, 3700 rpm, and 4200 rpm. The engine performance (power output effectively, SFC, and thermal efficiency), the ionization combustion (burning voltage and burning time) and exhaust gas emissions (HC and CO) were investigated. The results show that the additionof the HHO gascould improve the performance of the gasoline four-stroke engine. The effective of power out-put and thermal efficiency increase as increase the HHO injection.The specific fuel consumption (sfc) was also decreases as increases the HHO injection. The ionization combustion much better, which the voltage products of combustion increase and combustion time decrease as increase the HHO injection. The addition of HHO gas was also improved the quality of exhaust gas emission which are reduce the content of CO and HC gases due tothe HHO enhance the combustion process. The hydrogen gas has a high diffusivity which can improve of the fuel mixing, turbulence and homogeneity. The hydrogen gas has the flamehigh faster than gasoline, therefore its decrease the burning time as increase the HHO injection.Keywords: HHO, Hydrogen, Ionization, Gasoline Engine, Emissions

Abstract

The aim of this research is to investigate the effect of biodiesel percentage on the droplet combustion characteristic of calophyllum inophyllum biodiesel-diesel fuel blended. The combustion characteristic included ignition delay time, flame visualization, burning rate, and flame temperature. Testing was conducted using fuel blended with biodiesel percentage of 0%, 10%, 30%, 50% and 100%. The fuel was dripped and shaped a droplet that placed on the tip of thermocouple junction and ignited using a heater. The result shown that the ignition delay time increase with increasing biodiesel percentage due to its high flash point temperature and low volatility. Furthermore, burning rate and flame temperature increase with the increasing biodiesel percentage in the blended. These phenomena related to more microexplosion occurrence in the droplet combustion of fuel blended with higher biodiesel content. The last result shown that combustion of diesel fuel droplet has the highest flame dimension, related to its low burning rate and faster vapor diffusion rate.

Abstract

The research on the processing of organic municipal waste conversion has been done by using pyrolysis method. The research aims to gain an alternatif fuels and to minimize the landfill space. In the pyrolysis process, it was investigated the char formation as solid fuel as well as its heating value. The char formation was determined by the change of mass and volume of waste for minimizing landfill area.The waste compositions were obtained by surveying the 10 families during 10 days and then it was made the waste spesimens as the pyrolysis feedstocks. The pyrolysis processes were operated in range temperature 200oC to 400oC. Then, the char formations as pyrolysis products were tested by using bomb calorimeter to qualify the heating value of the products. The results showed that the waste was able to be a solid fuel due to the quality of its heating value. The increasing of the heating value could reach 150% from unpyrolyzed waste to pyrolyzed one. In addition, the pyrolysis method was able to significantly minimize the volume of waste, so that it has a potential way to overcome the need of a large landfil area in which it could reduce up to 50% in mass and 85% in volume. In waste pyrolysis method, it was only needed 2 hours operating process and low-temperature process (only up to 300oC). It did not require require a high-operating temperature, therefore, the handling of municipal organic waste to save area landfill and produce alternative fuel could be done in short time and did not require great energy.Keywords: waste, conversion energy, alternatif fuels, pyrolysis

Abstract

Abstrak Secara empiris, konsep pola PII mulai dikembangkan tahun 1980-an di negara-negara industri modern yang notabene memiliki faktor endowment relatif sama, yaitu cenderung padat modal. Konsep pola PII kemudian diadopsi negara-negara sedang berkembang yang secara konseptual juga memiliki kesamaan faktor endowment, yaitu cenderung padat tenaga kerja. Intensitas PII akan semakin tinggi apabila negara yang terlibat dagang adalah kelompok negara yang melakukan integrasi ekonomi (ASEAN). Tujuan penelitian yang ingin dicapai adalah untuk memperoleh gambaran intensitas PII antara Indonesia ASEAN-4, serta untuk memperoleh bukti empirik, menguji dan menjelaskan faktor-faktor yang mempengaruhi intensitas PII Indonesia dengan ASEAN-4, sehingga penelitian ini bisa digunakan sebagai acuan mengambil keputusan untuk memberlakukan pola PII sebagai salah satu cara untuk mengatasi instabilitas ekspor Indonesia akibat aktivitas ekonomi mitra dagang besar. Penelitian ini menggunakan metode Indeks Grubel-Lloyd dan analisis panel data. Hasil analisis data pertama, PII manufaktur Indonesia ke pasar ASEAN-4 periode 1985 - 2009 berdasarkan kode SITC cenderung mengalami pergeseran. Komoditi yang sebelumnya indeksnya tinggi pada tahun berikutnya menurun. Share intensitas PII antara Indonesia dengan ASEAN-4 masuk dalam kategori non-PII karena indeksnya < 40%; kedua, intensitas PII manufaktur didasarkan kode ISIC sudah masuk dalam kategori PII karena indeksnya sudah ≥ 40%, tepatnya 47,65% dan sisanya 52,35% berkategori non-PII, serta ketiga, estimasi model ekonometrik dengan metode FEM diperoleh hasil, yaitu intensitas tenaga kerja menunjukkan positif tidak signifikan, struktur pasar positif signifikan, skala ekonomi positif tidak signifikan, diferensiasi produk positif signifikan, dan dummy integrasi ekonomi positif signifikan.   Kata kunci: perdagangan intra-industri, struktur pasar, skala ekonomi, diferensiasi produk Abstract Empirically, the concept of IIT pattern was developed in the 1980s in modern industrialized countries which incidentally has the same endowment of factors, which tend to be capital intensive. IIT pattern concept was later adopted into the developing countries that are conceptually also have the same endowment of factors, which tend to be labor intensive. The intensity of IIT is believed to be higher if the countries involved are a group of countries that trade to economic integration (ASEAN). Research objectives to be achieved is to obtain a picture of the intensity of IIT between Indonesia and ASEAN-4, and to obtain empirical evidence, examine and explain the factors that influence the intensity of IIT Indonesia with ASEAN-4, so this study can be used as a reference to take a decision to impose a IIT pattern as a way to overcome the instability of exports of Indonesia as a result of major trading partners of economic activity This study used Grubel-Lloyd Index and panel data analysis. The results concluded the first manufacturing IIT of Indonesia to ASEAN market-4 during the period 1985 to 2009 according to SITC categories tend to experience a shift in which commodities are higher earlier in the year following the index declined. Share intensity of IIT between Indonesia with four ASEAN member countries are included non IIT category because it was < 40%; the second, the intensity of IIT in manufacturing based on ISIC category is included in the category of IIT because it was ≥ 40%, exactly 47.65% and 52.35% for the remaining non-IIT category, and third, the estimation in the model econometric conclusions obtained by FEM method, the intensity of labor showed no significant positive number.

Abstract

Purpose- This study aims to analyze Bank Indonesia monetary and macroprudential policy mix in achieving price stability as the goal of the policy.Design/methodology/approach- The variables were used in this study are inflation rate, asset price, exchange and credit rate, and inflation expectation, while the instrument used is the BI Rate which represents the monetary policy and GWM LDR which represents macro-prudential policy. The analysis method uses VAR by using data from the 2011M4-2018M5 periods.Findings- The VAR estimation showed that BI Rate affected the inflation rate through asset price, exchange rate, and credit. The GWM LDR instrument affected the inflation rate through asset price and credit. The IRF test showed that the shock on the BI Rate instrument was responded as negative by the inflation rate with 5 months lag, while the shock on GWM LDR as the macroprudential policy instrument was responded as negative by the inflation rate with 2 months lag. Implications- This indicates that the mix of monetary and macroprudential policy instruments can be used by BI in achieving its final policy objectives, and exploration of the selection of instruments used is needed. The findings show inflation expectations have a significant negative effect on the inflation rate in transmitting monetary policy by BI.Keywords: Policy Mix, Price Stability and VAR

Abstract

Development of the economy and improve the world economy which is increasing in the future. This causes an increase in trade in the same sector (Intra-Industrial Trade). In addition, promoting trade that focuses on fluctuating and unstable pushes Indonesia to further enhance its export competitiveness through market diversification, encouraging to minimize export fluctuations towards the main export destination countries. Commitment to a market diversification strategy has made Turkey an alternative export destination. The purpose of this research is to study the great integration of trade and export dynamics in the non-oil sector between Indonesia and Turkey during the period 2001-2016. Analysis using Gruble Lloyd Index (GLI) shows that the intensity of trade between Indonesia and Turkey is more in the category of Weak Integration (Weak Integration). While the analysis of the Constant Market Share (CMS) shows that each period is fluctuating, in the first period, the second period, the second period, the fourth period, the questioning period, the sixth period, the ninth period, the tenth period, and the second positive period, while in the seventh period , the eighth period, the eleventh period, the fourteenth period, and the twelve period of negative export value changes.

Abstract

The objective of this research is to investigate the droplet combustion characteristics of gasoline-ethanol fuel blended. The combustion characteristics included ignition delay time, burning lifetime, burning rate constant, flame height, flame temperature, and microexplosion. Testing was conducted using fuel blended with ethanol percentage of 0%(E0), 10%(E10), 20% (E20), 30% (E30) and 100% (E100). The fuel was dripped on the tip of the thermocouple junction and ignited using a torch of a butane-air mixture on a cylindrical burner. The results showed that the ignition delay time increase with the increase of ethanol percentage due to its high latent heat of evaporation and flash point temperature. However, flame temperature decrease with the increase of ethanol percentage due to the lower heat release rate of the mixture, related to the lower heating value of ethanol, and the burning rate constant of the fuels were not different significantly. The droplet diameter of the E100 (pure ethanol) decrease according to the d2?law, but the droplet diameters of the E0, E10, E20, and E30 changed drastically, exhibiting expansion and shrinkage. The Combustion of E20 fuel droplet has the highest burning rate constant, and flame height due to the oxygen content in ethanol can accelerate the combustion reaction and the fastest fuel droplet evaporates and diffuses into the air. Besides, the combustion of the E20 fuel droplet has the lowest burning lifetime due to the intensity of the microexplosion often makes the fuel droplet break into small droplets, which helps accelerate the process of evaporation and mixing of fuel with air, so that the combustion reaction occurs faster. Microexplosionphenomenon also identified due to the difference between the boiling point temperature gasoline and ethanol.

Abstract

This research was conducted to observe the effect of adding grooves in the two-phase flow of water-air in the same direction through a vertical pipe to changes in pressure and fluid flow patterns. Test section in the form of pipes with grooves made of acrylic material with a length of 100 cm and an internal diameter of 2.54 cm. The geometric shape of the acrylic pipe is modified by giving a groove in the direction of the pipe along the test section. Grooves used amounted to 4 and 16 and pipes without grooves used as a comparison. Tests are carried out by flowing water and air that has been mixed through the inlet side upward. The ratio of air velocity to water velocity (VG / VL ) is 0.24-1.13. The method used in this study is experimental. Retrieval of pressure drops data is done by using a differential pressure transmitter. Visual observations are also made using a DSLR camera equipped with a flash and video observations using a smartphone with slow-motion mode. The results showed changes in flow patterns and pressure drop values. Slugs in pipes with grooves disappear faster and pressure drops are lower than pipes without grooves.
