FISHERIES ADAPTIVE MECHANISM ANALYSIS AND LIVELIHOOD VULNERABILITY AT JAKARTA BAY
Authors: Robin Robin
Published: February 2019

This study has three purposes: 1) to analyze the characteristic of fishermen in Jakarta Bay, 2) to develop a conceptual model and the same time counting fisheries ecological footprint related to livelihood vulnerability. The data collection was done by triangulation method (observation, interview, and documentation). The sampling technique used snowball sampling with sample size was 15-30 samples. The method of analysis used in this research was descriptive qualitative for livelihood vulnerability based on Ellis’s (2000) equation and descriptive quantitative for fisheries ecological footprint (FEF). For FEF we used the equation based on Pauly & Christensen (1995). The results showed that there was a quite different characteristic between fishermen in Kamal Muara, Muara Angke and Kalibaru related to tribes,  fishing gear, income, adaptation model and education level. The livelihood vulnerability showed Fishermen at Muara angke much more vulnerable than fishermen at Kamal Muara and Kalibaru. For Fisheries ecological footprint showed that Jakarta bay ecosystem is overshot meant the biocapacity much lower than ecological footprint that is 4178 km2 to 6978 km2 (Fishing Ground). A conceptual model was developed to describe the relationship between livelihood vulnerability and Fisheries Ecological Footprint. This model strongly divided the fisherman adaptation models into two routes of management.

Stifling of Customary People Political Voice of Recognition in Political Economy Perspective (Case Study on Mapur Tribe Lom Bangka Belitung)
Authors: Zulkarnain Iskandar , Soetarto Endriatmo , Sunito Satyawan , Adiwibowo Soeryo
Published: February 2019

Symptoms of political neglection along with changes in capitalist-oriented economic development policies have become a major challenge for recognition of indigenous people in Indonesia. The experience of the Mapur Lom tribe marks the phase of detachment of an entity from its agrarian tradition. This study aims to identify the future critical point of Lom people due to the absence of recognition from the government which more prioritizes the practices of power domination and penetration of capital. The case study was used to oversee the socio-economic relations between tin and oil palm as well as the dynamics of actors contestation who were legitimized by the post-New Order bureaucracy. Data collection uses interviews, observation, document studies, and focused discussions. The results of the research show that the mechanism of stifling the political voice of Lom people's recognition takes place through two phases, namely silencing from within by the apparatus at the hamlet level by hijacking the autonomy discourse of customary forests. The second phase, preclusion of political voices from outside through a continuous changing of regulations, policies that tend to favor the oil palm plantation corporations, capital intervention accompanied with land grab and violence. Working with Marxian perspective elaboration and critical perspective see that failure of state and bureaucracy at the regional level related to political economy of recognition are the result of perpetuating power domination based on concentration of regulation, policy, legitimacy, and capital along with collusion with corporations against individuals, groups and nature.

Research on the impact of diesel injection parameters on particulate matters emission in a dual-fuel supercharged engine fueled with natural gas
Authors: Skrzek Tomasz , Jarzyński Grzegorz
Published: February 2019

The paper presents the results of research on dual-fuel, compression ignition engine, powered by natural gas. The main objective of the conducted research was to determine the impact of injection parameters initiating the ignition of a diesel oil dose, i.e.: the size and injection timing, on the emission of particulate matters. Studies have shown that when using a split of the diesel dose for the pilot and main dose, despite the significant (70%) share of natural gas in the mixture being combusted, the emission of particulate matters is comparable and even higher than that obtained on standard fuel. Previous studies of the dual-fuel engine showed that there is a clear need to divide the diesel dose into a pilot dose and the main dose. This division significantly affects the course of heat release, and at the same time is an effective method of reducing the maximum rate pressure rise, which allows increasing the share of gaseous fuel. From the point of view of particulate emissions, such division is counterproductive. The obtained results indicate that the values of pilot and main doses and their injection timing significantly affect the conditions of formation of particulate matters.

Practical application of wavelets in the engine's vibroacoustic analysis
Authors: Wróbel Radosław , Andrych-Zalewska Monika , Ambroszko Wojciech , Fryda Szymon
Published: February 2019

Vibrations are most often measured using ceramic piezoelectric sensors - accelerometers. The accelerometer uses a piezoelectric effect to measure the dynamic acceleration of its housing. They are mounted directly on the measuring system (moving or rotating, such as gearboxes, rotating blades, turbine engines or bearings). This is not their only use, because they can also be used in shock measurements, such as NCAP in the field of automotive safety or diagnostics (unfortunately they have lower accuracy than low-frequency LDV). The main advantage of using a piezoelectric accelerometer is its linearity in a wide range frequency and a huge range of work dynamics. Engine vibration measurements are usually made at different points of the engine to be independent of each other. The engine block is a characteristic measuring point because it is best available. Accelerometers are assembled by glue, screwing or magnetic connection. The obtained vibroacoustic signal is most often analyzed using Fourier analysis. The following article presents another possibility of on-line analysis: short-term wavelet analysis "on-line".

Analysis of selected aspects of the railway safety in the European Union
Authors: Ciszewski Tomasz , Nowakowski Waldemar , Chrzan Marcin
Published: February 2019

Sustainable development of railway companies is conditioned by safety, which is why each railway operator should continually strive to improve safety and reduce the number of accidents. The requirements for reporting incidents and analyses are regulated at the European Community level. The regulatory authorities - national and European - are responsible for monitoring the safety culture. On the basis of the acquired data and safety indicators the authors analysed trends related to the European railways safety level. Comparative analyses carried out for individual EU countries allowed to find the main causes of accidents and indicate selected corrective actions that can be taken to improve safety and reduce accident costs. Previous practical experiences show that the costs of preventive actions are much smaller than the costs of eliminating the effects of accidents. Although the results of the analysis clearly show that consistent efforts in the safety area lead to a structural reduction in the number of accidents, there is still significant scope for improvements in many areas.

Cytological characterization of three closely related pines - Pinus mugo, P. uliginosa and P. × rhaetica from the Pinus mugo complex (Pinaceae)
Authors: Celiński Konrad , Chudzińska Ewa , Gmur Aneta , Piosik Łukasz , Wojnicka-Półtorak Aleksandra
Published: February 2019

The Pinus mugo complex comprises closely related pines in different taxonomic ranks, which commonly occur in major European mountain chains. This large and polymorphic complex has been, and still is, a considerable challenge for taxonomists due to highly variable phenotypical characteristics within particular taxa, ongoing hybridization in sympatric populations, lack of distinct morphological species-specific determinants, and the absence of distinct genetic differentiation among them. Moreover, cytogenetic data on pines from this complex are very scarce. Therefore, in this study, we used C-banding methods and flow cytometric analysis in order to provide new data on karyotypical features and DNA content of three closely-related pines from the Pinus mugo complex, i.e., Pinus mugo (Turra), Pinus uliginosa (Neumann), and Pinus × rhaetica (Brügger) and to gain more insight into the taxonomic relationships between these pines. Our results confirmed that the basic number of chromosome is the same amongst the analyzed taxa (2n = 2x = 24), and that the karyotypes have a similar morphology. The number of secondary constrictions (SCs) and C-banding patterns differed slightly between P. mugo, P. uliginosa and P. × rhaetica. The nuclear DNA content (2C/pg) among analyzed taxa is from 46.41 pg for P. mugo and P. × rhaetica to 46.48 pg for P. uliginosa. For each of these pines, certain taxa-specific cytogenetic determinants were identified. Our results indicate that they may represent two different taxa, and so their names should not be used interchangeably in scientific literature.

The manufacturing of physical device of electrostatic precipitator (ESP) requires a costly budget. The risk of performance failure of an ESP device could be minimized by simulating an ESP using a finite element method program. The performance of the ESP model of parallel plate type using COMSOL Multiphysics program was simulated in this research. The ESP geometric model was drawn in 3D specifically, then it was integrated using laminar flow, electrostatic and particle tracing studies. Laminar flow and electrostatic studies are simulated simultaneously and the results are coupled by a study of particle tracing. The simulated test particle consists of two types: particles with physical features of 60 to 100 mesh and microparticles 0.5 to 1 μm. The result showed a good agreement between the simulations and the experiments. The size and type of particle are crucial to the successful performance of an ESP device.  Keywords: electrostatic precipitator, COMSOL multiphysics, microparticle Pembuatan perangkat fisik electrostatic precipitator (ESP) membutuhkan biaya yang cukup mahal.

Currently, the turbine oil cooling regulator systems at Banten 3 Lontar power plant are still manually operated. Historically there have been failures due to negligence caused by manual operation pattern. In addition, several published researched in a similar case for temperature control are usually using proportional integral (PI) control system. In this paper, automatic operating system with PI controller is designed to facilitate easy operation and to maintain reliability of the unit. The method that used to determine PI constant is to find the transfer function plant and simulate it with Matlab, then analyze the data and provide recommendations for research with the results that it can be applied in the power plant unit. The simulation results are in accordance with the design goals where the response time gives a quick response of 1 second, the overshoot error is minimum and set points equal to steady state. The design of the control system is simulated by being given disturbance from the external because all systems in the power plant unit are susceptible to disturbance. At the first disturbance, the temperature overshoot is up to 26.5 °C and stabilized after 8 seconds. Whereas the second disturbance, the temperature overshoot is up to 43 °C and stabilized after 11 seconds. Both have 1 second response time. Temperature changes that occur with a set point that has been determined in the first and second disturbances are +1.5 °C and +1 °C. Saat ini sistem pengatur pendinginan oli turbin di PLTU Banten 3 Lontar masih dioperasikan secara manual. Secara historis pernah terjadi kegagalan akibat kelalaian karena pola operasi yang masih manual. Selain itu beberapa penelitian yang pernah dilakukan sebelumnya pada kasus serupa, untuk pengendalian temperatur, yang umum digunakan adalah kendali proporsional integral (PI). Pada penelitian ini dilakukan perancangan sistem pengoperasian otomatis dengan kendali PI agar lebih memudahkan penoperasian dan menjaga keandalan unit. Metode yang digunakan untuk menentukan konstanta pengendali PI adalah dengan mencari fungsi alih plant dan mensimulasikannya pada software Matlab, menganalisis data, dan memberikan rekomendasi aplikasi pada unit pembangkit. Hasil simulasi ini sesuai dengan tujuan perancangan di mana time response memberi tanggapan yang cepat yaitu 1 detik, error overshoot minimum, dan set point sama dengan steady state. Sistem pengendali juga diuji pada kondisi diberi gangguan karena semua sistem yang ada di unit pembangkit rentan terhadap gangguan. Pada gangguan pertama, sistem menanggapi dengan cepat, overshoot temperatur hingga 26,5 °C dan stabil setelah 8 detik. Pada gangguan kedua, overshoot temperatur hingga 43 °C dan stabil setelah 11 detik. Keduanya memiliki time response selama 1 detik. Perubahan temperatur yang terjadi setelah diberi gangguan dengan set point yang telah ditentukan pada gangguan pertama dan kedua sebesar +1,5°C dan +1°C.

The wind power plant is one of the renewable energy source that can reduce the environmental and social impacts caused by fossil power plants. Furthermore, it requires protection systems, such as ground protection system for the safety of personnel and devices that use electricity as a power source from electric surges. In this paper, analysis of the 2.5 MW wind power plant grounding system design in Sidrap South Sulawesi is presented. The analysis was done using ETAP 16.0 software to determine the value of actual touch voltage, step voltage, and grounding resistance. The ETAP simulation results show that the value of actual touch voltage is 2162.8 V, step voltage is 726.2 V, and the grounding resistance is 0.8  W. The results indicate that wind power plant grounding systems are able to keep humans and devices around the power plant safe.Pembangkit listrik tenaga bayu (PLTB) merupakan suatu pembangkit energi terbarukan yang dapat mengurangi dampak lingkungan dan sosial yang ditimbulkan oleh pembangkit listrik tenaga fosil.

KAJIAN PEMODELAN MATEMATIKA TERHADAP PENYEBARAN VIRUS AVIAN INFLUENZA TIPE-H5N1 PADA POPULASI UNGGAS
Authors: Putri Dian Permana , Sulaiman Herri
Published: February 2019

Seperti yang dikutip dari Centers of Disease Control and Prevention, Avian Influenza (AI), atau sering disebut dengan flu burung adalah penyakit menular yang disebabkan oleh virus H5N1 tipe A pada unggas. Virus H5N1 diklasifikasikan ke dalam dua kategori yaitu patogenik rendah dan patogenik tinggi yang mengacu pada kemampuan virus untuk menyebabkan penyakit parah (berdasarkan karakteristik molekuler dari virus dan mortalitas pada unggas di bawah kondisi percobaan). Virus H5N1 hidup dalam saluran pencernaan unggas sehingga unggas yang terinfeksi dapat mengeluarkan virus ini melalui tinja yang kemudian mengering dan hancur menjadi semacam bubuk. Bubuk inilah yang kemudian dihirup oleh manusia atau binatang lainnya. Pada penelitian ini, untuk mempresentasikan pola penyebaran virus Avian Influenza pada populasi unggas dibuat ke dalam bentuk model matematika dengan menggunakan Sistem Persamaan Diferensial Nonlinear (PDNL). Dari fakta yang ada mengenai virus Avian Influenza, dibentuk asumsi yang nantinya digunakan untuk membuat model matematika. Setelah model matematika terbentuk lebih lanjut dicari titik ekuilibrium model dan dianalisis apakah titik ekuilibrum yang ditemukan stabil asimtotik atau tidak, kemudian diakhir penelitian ditentukan simulasi numeris dengan membuat plot/grafik dari sistem model matematika agar dapat diinterpretasikan pada keadaan yang sebenarnya.Kata kunci : Avian Influenza, Pemodelan Matematika, Titik Ekuilibrium, Kestabilan
