NUMERICAL SIMULATION OF IRREGULAR BIMODAL WAVE SYSTEM DYNAMICS WITHIN THE FRAMEWORK OF KORTEWEG-DE VRIES EQUATION
Authors: Didenkulova E.G. , Slunyaev A.V. , Pelinovsky E.N.
Published: October 2019

The dynamics of wave ensembles in shallow water is studied within the framework of the nonlinear dispersive Korteweg – de Vries (KdV) equation by numerical simulation. Bimodal wave systems whose energy is distributed over two spectral domains are considered: the “additional” lobe which corresponds to the system of longer or shorter waves is added to the “main” spectral peak. The concerned problem describes, for example, the interaction between wind waves and swell in shallow water. The case of the unimodal waves (considered in (Pelinovsky, Sergeeva, 2006) is used as the reference. The limitations of the implied assumptions and the relationship of the idealized model to the realistic conditions in the ocean were discussed in the recent paper (Wang et al, 2018).
Based on the detailed consideration of the 6 simulated cases, the following general conclusions may be formulated.
The transition from the initial state to the quasi-equilibrium one is accompanied by strong variations of the wave characteristics, when the waves exhibit the most extreme features. In particular, the wave kurtosis grows suddenly and the abnormal heavy tails in the wave amplitude probability distributions appear. These processes are observed in all the cases of the bimodal spectra and are quite similar to the single-mode regime. The coexistence of a long-wave system smoothens the rapid oscillations of the wave extremes and kurtosis which take place during the transition stage.
The presence of a short-wave system makes the waves on average more symmetric. Skewness attains the minimum value compared to the other cases. The co-existence of shorter waves practically does not change the wave kurtosis or the probability of the wave heights.
In contrast, the presence of a long-wave system makes the waves more asymmetric and more extreme. The probability of large waves increases in the bimodal systems with a low-frequency component.
The initial wave spectrum expands as a result of the wave interaction and tends to a quasistationary state. One may anticipate that the formulated conclusions are applicable beyond the limits of the Korteweg-de Vries equation to other kindred frameworks and corresponding phenomena.

TWO-PHASE ASYMPTOTICS IN THE FORM OF AIRY FUNCTIONS IN THE WAVE BREAKING PROBLEM FOR THE I-BURGERS EQUATION
Authors: Dobrokhotov S.U. , Nazaikinskii V.E.
Published: October 2019

We consider wave breaking problems for the Burgers equation with a small “imaginary viscosity,” which in fact plays the role of small dispersion. Although this equation has no apparent physical meaning, the problem in question is an interesting analog of the famous Gurevich-Pitaevsky problem on the onset of an oscillation zone as the breaking of a simple wave occurs for the Korteweg-de Vries equation. In contrast to the latter, the solution of the i-Burgers equation in the oscillation zone can be described explicitly and has a two-phase structure. This was indicated more than 25 years ago in (Dobrokhotov et al., 1992), where the solution was constructed in the form of a function of Maslov’s canonical operator. Now we use the recent results in (Dobrokhotov, Nazaikinskii, 2018) to present the solutions in the more efficient form of uniform asymptotics represented as the logarithmic derivative of the Airy function of a composite argument.

NUMERICAL SIMULATION OF WEAK TURBULENCE OF ELECTROCAPILLARY WAVES ON THE SURFACE OF A LIQUID DIELECTRIC
Authors: Zubarev N.M. , Kochurin E.A.
Published: October 2019

In the present work, direct numerical simulation of the interaction of plane capillary waves on the surface of a liquid dielectric in an external tangential electric field with allowance for viscosity forces has been carried out. In the limit of a strong electric field, when viscous and capillary forces can be neglected, at which the curvature of the boundary increases significantly singular points can form at the boundary of the liquid (Zubarev, Kochurin, 2014, Kochurin, 2018, Kochurin, Zubarev, 2018). In the case of a finite electric field, the interaction of opposing nonlinear electrocapillary waves can lead to the appearance of a direct energy cascade. In the quasi-stationary energy dissipation regime, the probability density functions for the angles of the boundary inclination tend to the normal Gaussian distribution, and the shape of the boundary takes on a complex, chaotic form. The spectrum of the surface disturbances in this mode is described by a power dependence of k–5/2. In terms of energy, the resulting spectrum has the form k–3/2, which coincides with the Iroshnikov-Kraichnan energy spectrum and indicates that the observed wave turbulence of the liquid surface and weak magnetohydrodynamic turbulence of interacting Alfven waves have a related nature.

NONLINEAR DYNAMICS OF LONG-WAVE PERTURBATIONS OF THE INVISCID KOLMOGOROV FLOW
Authors: Kalashnik M.V. , Kurgansky M.V.
Published: October 2019

The nonlinear dynamics of long-wave perturbations of the inviscid Kolmogorov flow, which models periodically varying in the horizontal direction oceanic currents, is studied. To describe this dynamics, the Galerkin method with basis functions representing the first three terms in the expansion of spatially periodic perturbations in the trigonometric series is used. The orthogonality conditions for these functions formulate a nonlinear system of partial differential equations for the expansion coefficients (Kalashnik, Kurgansky, 2018). Based on the asymptotic solutions of this system, a linear, quasilinear and nonlinear stage of perturbation dynamics are identified. It is shown that the time-dependent growth of perturbations during the first two stages is succeeded by the stage of stable nonlinear oscillations. The corresponding oscillations are described by the oscillator equation containing a cubic nonlinearity, which is integrated in terms of elliptic functions. An analytical formula for the period of oscillations is obtained, which determines its dependence on the amplitude of the initial perturbation. Structural features of the field of the stream function of the perturbed flow are described, associated with the formation of closed vortex cells and meandering flow between them.

REFLECTION FROM THE NEUTRON STAR SURFACE UNDER CONDITIONS OF PLASMON-POLARITON RESONANCE AND ADDITIONAL COMPONENTS IN THE EMISSION OF A PULSAR IN THE CRAB
Authors: Kontorovich V.M. , Spevak I.S. , Gavrikov V.K.
Published: October 2019

Additional relative to the main pulse and interpulse HF-components in the radiation of a Crab pulsar are observed in the same range where the interpulse shift occurs (Moffett, Hankins, 1996; Hankins, Jones and Eilek, 2015). The latter is explained by the specular reflection from a neutron star surface of returned positron radiation in an inclined magnetic field (Kontorovich, Trofimenko, 2017). Therefore the additional HF-components, which are substantially shifted in the rotation phase of the pulsar, can be naturally associated with (nonlinear) reflection – diffraction on the surface periodic structure. It is significant that such a structure can arise as a result of stimulated scattering on surface waves, and this scattering can occur under conditions of plasmon-polariton resonance associated with the diffraction spectrum sliding along the surface, which significantly reduces the stimulated scattering threshold. The large width of the components is explained by the continuous radiation spectrum of returned positrons incident on the surface. Although this mechanism found itself in the Crab pulsar due to a unique combination of parameters at centimeter wavelengths, it is completely common to pulsars. Another possibility – diffraction by a periodic structure due to the action of constant fields (electric or magnetic) − requires some separate consideration.

IRREVERSIBLE HYSTERESIS OF 3D-TOPOLOGICAL TANGLE LASER SOLITONS
Authors: Veretenov N.A. Veretenov , Rosaov N.N. , Fedorov S.V.
Published: October 2019

In a laser medium with saturable amplification and absorption or in a laser with such a medium and a sufficiently large cavity length, the authors previously demonstrated a class of dissipative three-dimensional topological solitons (Veretenov et al., 2016, 2017). Such solitons have “skeletons” – a set of several closed and unclosed vortex lines, on which the field turns to 0 and the phase of which bypass is incremented by a multiple of 2π. It is significant that the regions of the scheme parameters in which different types of topological solitons exist and are stable, overlap. Accordingly, the question arises about the nature of changes in the structure of solitons and their skeletons with a slow change in the parameters. The answer to this question, mainly in the framework of numerical modeling, is the subject of this report.
The initial equation is the generalized Ginzburg-Landau complex equation for a slowly varying envelope of the field, with the longitudinal coordinate along the path of preferential propagation z (Veretenov et al., 2017) serving as an evolution variable. The control parameter is the coefficient of linear (unsaturated) field gain g0. The initial value of this parameter corresponds to the central part of the stability region of the original soliton (for definiteness, the “Solomon soliton”). Then g0 slowly increases, crossing the stability boundary, after which it stabilizes and slowly decreases, eventually returning to its original value.
We demonstrate that as a result of such a hysteresis cycle, the soliton does not return to the initial one — its structure is drastically simplified. This is reflected in a decrease in the values of various topological indices, as well as in a decrease in the field energy and an increase in the energy of the active medium (minus its constant background). At the g0 reduction stage, the topological characteristics do not change (two “soliton-apples”). The transient process includes a series of elementary reactions of reconnection of the vortex lines and detachment of closed loops after a strong bend of the “parent” vortex line. In addition, during the transition process, a number of new types of localized topological metastable structures arise.

AN EXACTLY SOLVABLE MODEL OF INTRUSION
Authors: Goncharov V.P.
Published: October 2019

The conformal-mapping approach (Bazant, Crowdy, 2005; Tanveer, 1993; Zakharov, Dyachenko, 1996; Yoshikawa, Balk, 1999, 2003) is used to formulate a minimal exactly solvable model for studying the lock-exchange gravity currents in an infinite horizontal channel (Simpson, 1999; Ungarish, 2009). The distinctive feature of such flows is a pressure jump which arises at the interface between two incompressible fluids of different densities at once after removing a lock gate. Because of this, the process of intrusion does not fit into Benjamin’s scenario (Benjamin, 1968) but rather is like propagation of two shock waves.

Published: October 2019

This study aimed to examine on some properties and to draw attention to why it cannot create an intensive stock amount of Chamelea gallina (Linnaeus, 1758) in the Gulf of Antalya in the Mediterranean coast of Turkey, Levantine Sea. Specimens of C. gallina displayed total shell legths of 6 to 32 mm, mean 14.5 mm and total weights of 0.1 to 11.44 g, mean 1.82 g. The total shell length and total weight relationship of C. gallina was calculated as TW =0.3333 * TSL 2.9894 (R² =0.9850). The mean meat yield was found as 12.10±0.9264%. A small number of C. gallina samples were collected. The majority of the collected striped venus were determined as empty shell. It was observed that the razorfish (Xyrichtys novacula) were fed with C. gallina during research. Finally, these results may draw attention the reasons why this species cannot form an intensive stock amount. It is thought that the empty shells of the striped venus can be caused from feeding of the razorfish (X. novacula) with C. gallina and environmental factor changes.Keywords: Chamelea gallina; length; weight; meat yield; mediterranean

K-Nearest Neighbor is a method that can classify data based on the closest distance. In addition, K-NN is one of the supervised learning algorithms with learning processes based on the value of the target variable associated with the value of the predictor variable. In the K-NN algorithm, all data must have a label, so that when a new data is given, the data will be compared with the existing data, then the most similar data is taken by looking at the label of that data. Filling and processing many questionnaires to determining the results of lectural evaluation from the performance of lecturers certainly requires a lot of time and process. Therefore, it is necessary to apply the K-NN Manhattan Distance method. In this study, the testing data is taken from one of the training data and has a classification result that is "Very Good". After going through the K-NN Manhattan Distance method with k being the closest / smallest neighbor, then the following results are obtained: Distance 5.4, the classification result is "Very Good" and 74.03% of similarity value. Based on the results obtained, the result of the classification from K-NN Manhattan Distance method show similarities with the results of the pre-existing classification.

There are many new rice varieties have been produced, introduced and breed at IRRI and the other National Agriculture Research Institutes that are tolerance to submergence condition to anticipate global warming and flash flooding around theworld. Among others are IR64-Sub 1, Suwarna-Sub 1, Inpara-1, Inpara-2, inpara-3 etc. However, those new varieties have not been tested widely yet, and the method of rice cultivation under submergence condition have not been adjusted, including the nutrient management.A greenhouse experiment was conducted at Muara Research Station, Bogor during 2008 dry season. The objectives of this experiment are (1) to study the effects of time of submergence and N application on plant growth and yield of  R64 and IR64-Sub 1 rice varieties; (2) to find the best nutrient management for submergence rice varieties. The experiment was conducted during 2008 dry season at greenhouse, Muara Research station, Bogor. The design of the  experiment was a Completely Randomized Factorial Design with three eplications. Factor 1 is rice variety (IR64 and IR64-Sub 1); Factor 2 is time of submergence (without submergence or control, submergence at vegetative phase (15 to 25 d.a.t), and at generative phase (35 to 45 d.a.t)). Factor 3 is N application, namely (F1) 300 kg Urea/ha 3x applications at 7 d.a.t- 30 d.a.t – 55 d.a.t; (F2) Mudball urea –300 kg Urea/ha applied once at 7 d.a.t. (F3) compost; and (F4) compost and urea; (F5) Urea and silikat.urea-N application at four time 0 d.a.t – 7 d.a.t – 30 d.a.t – 55 d.a.t (factor C). The results of experiments showed that submergence changes rice plant growth pattern (mainly tiller number and plant height), increased dry grain weight of IR64, namely 35.9 g at early vegetatif phase and 29.9 g at late vegetatif phase, while for IR64-Sub 1 32.6 g and 30.3 g at the same respective phase. Mudball urea and silicate application improved plant resistant to submergence and increase rice yield.

Los rodales pueden ser afectados por diversos factores, como los fenómenos naturales o el manejo forestal, porque modifican su estructura y el volumen maderable residual. La cuantificación del volumen removido en una intervención silvícola suele ser difícil, pero después de la aplicación de tratamientos silvícolas queda como evidencia el tocón; con base en sus dimensiones, es factible generar modelos de regresión para conocer el diámetro normal, la altura y el volumen en pie. Así, se midieron 83 árboles con un dendrómetro a fin de obtener la ecuación más confiable para determinar la relación funcional: a) diámetro normal–diámetro del tocón; b) altura total-diámetro del tocón; y c) volumen total-diámetro del tocón. Se ajustaron modelos lineales y no lineales a las relaciones establecidas. Para elegir el mejor modelo se utilizaron diferentes criterios de bondad de ajuste: el coeficiente de determinación, la raíz del error medio cuadrático y el coeficiente de variación. Con una ecuación lineal simple es posible predecir la relación diámetro normal-diámetro del tocón y con una ecuación polinomial, la relación altura total-diámetro del tocón. Para la relación volumen-diámetro del tocón, se generó un sistema de ecuaciones con efecto multiplicativo con el propósito de corregir la heterocedasticidad. Las ecuaciones dieron resultados estadísticamente confiables para predecir las variables de interés.

It is also taught to students of simple Arabic wholesale. However, from the information obtained by the researcher from the Arabic teacher he says that the students could not master this skill, this situation can be seen from their duties in translating the Arabic language into Indonesian language still suffer from limitations in the syntax of the sentences and the choice of words in the particular expression. The difficulty of the text can be related to the translator's level of ability. There are two things that are interrelated: the text is easy because the translator's level of ability is very good, or the text is difficult because the translator's level of ability is still very low. This background is what drives the researcher to look into the problem of translation that is happening to students at the second Inter-Governmental Secondary School Bengkulu.

Abstract This research is about "similarities and differences between Arabic and Indonesian in the phenomenon of tandem - and how to deal with this phenomenon in teaching Arabic to Indonesians." The importance of Arabic is also reflected in the fact that is the key of Islamic and Arab culture. It allows learner to learn about the cultural and intellectual dimensions of a nation that has been crowned on the throne for centuries. It has left a great cultural heritage in various arts and sciences.The importance of Arabic stems from the fact that it is one of the strongest links and links between Muslims. Language is one of the most important elements of unity among Islamic societies. Arabic is no longer a language specific to Arabians, but has become a universal language for millions of Muslims in the world today demand for their connection to their religion and Islamic culture. We also see a desire to learn the arabic language for non-Muslims to communicate with the people of the language on the one hand and to communicate with the Arab and Islamic heritage on the other.Features of Arabic Tandem. It is an important factor in the growth of language, two words or more that indicate one meaning. We can use it without separating them. The speaker observes the exact order in the choice of the word of the synonyms corresponding to the sentence.It is interesting that Arabic is the only language that gives citizenship to anyone who speaks it. "Whoever learns Arabic is an Arabian."There is almost unanimous agreement that tandem is one of the reasons for the richness of language in vocabulary, whether it is Arabic, Indonesian, or other languages. And its privilege with a wealth of words. There have been many works that collected the vocabulary of this phenomenon in the ancients in particular, which reinforces this statement to the extent that it is surprising, such as the names of one thing to thousands of words.

The immigration of Prophet Muhammad, otherwise known as the Hijrah, was not about running away from being killed, nor was it about fear, or a retreat from bidding the lawful or forbidding the unlawful. The Hijrah was done in obedience to what Allah had ordered.  During the Hajj season, when the people gathered, the Prophet peace be upon him used to call them to Islam and say to them: “say no one is God except Allah and then you will succeed”.The Prophet was very patient with what the blasphemers had done to him. His companions tolerated many types of torture including whipping, hitting, imprisonment, burning, and execution. Yet when they gained the support and aid from Allah, it was as if they had turned into a solid rock that could not be scratched. Their pious heartbeats and their silent supplications shook the hearts and thrones of the disbelievers.Keyword: Immigration, Prophet Muhammad, Hijrah

El presente artículo tiene como objetivo mostrar, desde una perspectiva crítica, los límites del concepto de víctima implícitos en la Ley 1448 de 2011, conocida como Ley de Víctimas y Restitución de Tierras. Para lograrlo, se tienen en cuenta los siguientes pasos: en primer lugar, el análisis sobre el concepto de víctima a partir de la filosofía política y su relación con la violencia en perspectiva hermenéutica; en segundo lugar, la profundización en la noción de víctima desde el ejercicio real de ciudadanía; y, en tercer lugar, la interpretación de las limitaciones de la noción de víctima desde la equidad de género. El resultado: existe un concepto de víctima excluyente e inoperativo el cual promueve la segregación y limita, tanto el ejercicio real de ciudadanía como la equidad de género en Colombia. En síntesis: una noción de víctima que profundiza las relaciones de poder y perpetúa las violencias resultantes del conflicto armado colombiano.

This paper aims to investigate the minimum threshold for zero crossing detection of the first return stroke in negative cloud-to-ground lightning flashes. The uncertainty for a minimum threshold to be set into a programmed software for an automatic zero crossing detection motivated the author to overcome the problem. The software was built-in MATLAB. The development of the software considered the important parameter of lightning strike from the preliminary breakdown stages until the first return strokes. A single station measurement was setup in Ayer Keroh, Malacca. 41 samples of duration of the zero crossing time were recorded by using Lecoy HDO4024 with 5 MS/s. The results showed that the minimum threshold for zero crossing detection was 40µs with 82.9% accuracy. In conclusion, the minimum threshold of zero crossing detection of the first return stroke in negative cloud-to-ground was determined.

Authors: Pertiwi Sri Rejeki Retna , Mardiah Mardiah , Hapsari Distya Riski
Published: October 2019

Talas mengandung mucilage yang larut dalam air panas, membentuk larutan kental dalam air dingin, dan tidak larut dalam pelarut organik.  Penelitian tentang isolasi mucilage telah banyak dilakukan dengan menggunakan pelarut organik seperti alkohol dan aceton.  Titik kritis keharaman dan keamanan isolasi mucilage adalah residu pelarut organik yang digunakan pada tahap presipitasi. Tujuan penelitian ini adalah mengetahui metode presipitasi  yang mampu menghasilkan mucilage berpotensi sebagai pengganti gelatin halal.  Pada penelitian ini, isolasi mucilage dilakukan melalui tiga tahap, yaitu ekstraksi dengan air panas, diikuti dengan presipitasi dan pengeringan.  Metode presipitasi yang diteliti ada tiga, yaitu pendinginan, alkohol, dan aceton. Mucilage yang dihasilkan kemudian dianalisis sifat-sifatnya, yaitu sifat sensori, fitokimia, dan fisikokimia. Sifat-sifat Gelatin bloom 200 juga dianalisis dan digunakan sebagai standar.  Hasil penelitian menunjukkan bahwa mucilage yang dihasilkan dengan presipitasi pendinginan memiliki sifat-sifat lebih baik dibandingkan mucilage dengan presipitasi alkohol maupun aceton dan mendekati sifat-sifat gelatin.  Metode presipitasi dengan pendinginan pada isolasi mucilage talas berpotensi menghasilkan mucilage sebagai pengganti gelatin halal. Kata kunci: aceton, alkohol, pendinginan, mucilage, talas.

Pengendalian kondisi udara di ruang produksi perlu dilakukan untuk menjaga kualitas dari produk yang dihasilkan khususnya di industri farmasi. Penelitian ini bertujuan untuk mengkaji pengawasan mutu cangkang kapsul kosong secara mikrobiologis, mendeskripsikan metode yang digunakan pada pengukuran kualitas udara di ruang produksi, menganalisis pengaruh faktor udara terhadap mutu cangkang kapsul yang diproduksi, dan meramalkan mutu produk (nilai TAMC (Y)) berdasarkan variabel-variabel udara (suhu (X1), kelembaban (X2), dan cemaran mikroba udara (X3)). Metode yang digunakan dalam penelitian adalah metode time series, metode settle plate, uji TAMC, dan metode regresi linear berganda. Hasil perhitungan dengan menggunakan metode regresi liniear berganda dengan taraf nyata 5 persen didapatkan persamaan Y = 19.47 + 5.838X1 – 5.622X2 – 0.054X3 + e, dari model regresi tersebut menghasilkan nilai P (sig. F) sebesar 0.079 dengan nilai koefisien determinasi (R) sebesar 0.284. Dari hasil perhitungan tersebut dapat dinyatakan bahwa faktor udara di ruang produksi tidak berpengaruh nyata secara simultan terhadap nilai mutu produk, serta menunjukkan bahwa secara parsial hanya variabel suhu yang berpengaruh signifikan dengan arah hubungan yang positif.Kata kunci: ruang produksi, sistem AHU, Total Aerobic Microbial Count, regresi linier

KEPASTIAN HUKUM TERHADAP HAK MILIK DIATAS HAK PENGELOLAAN DIKOTA BATAM
Authors: Maileni Dwi Afni
Published: October 2019

Hak Pengelolaan yang diberikan kepada BP Batam secara parsial diberikan Hak Guna Bangunan dan Hak Pakai, namun prosesnya tetap melakukan pendaftaran tanah di kantor Badan Pertanahan Kota Batam. Dengan pengaturan tersebut terdapat perbedaan dalam prosedur kepengurusan status Hak atas Tanah di Kota Batam dengan kota lainnya. Jika di kota lain di Indonesia melalui alas hak adat proses untuk memperoleh sertifikat dapat dilakukan langsung ke Badan Pertanahan Nasional, tidak demikian dengan di Kota Batam, dimana proses pendaftaran tanah harus dilakukan terlebih dahulu dengan proses permohonan tanah, dikarenakan kekhususan Kota Batam yang dibentuk berdasarkan Keputusan Presiden Nomor 41 Tahun 1973 tersebut yang menyatakan bahwa seluruh tanah yang berada di Kota Batam adalah berbentuk Hak Pengelolaan. Mengenai sertipikat Hak Milik di Kota Batam, apabila ditinjau dari peraturannya memang tidak ada Hak atas Tanah berupa Hak Milik diatas Hak Pengelolaan. Berdasarkan Peraturan Pemerintah Nomor 40 Tahun 1996 menyatakan bahwa di atas tanah Hak Pengelolaan dapat diberikan atau dibebankan dengan hak-hak atas tanah yaitu Hak Guna Bangunan dan Hak Pakai. Status kepemilikan Hak Milik diatas Hak Pengelolaan

Lembaga anti rasuah di Indonesia (KPK) dengan struktur yang ada, telah melakukan berbagai cara, baik untuk pemberantasan maupun pencegahan korupsi di Indonesia. Upaya di bidang penindakan mengalami peningkatan pada tahun berikutnya. Usaha keras menghapus dan mencegah korupsi oleh KPK patut mendapatkan apresiasi. IPK Indonesia tahun 2018 naik sedikit hingga mencapai 38, namun jika dilihat dari perspektif tingkstan, maka negara Indonesia yang masih di angka 89, dengan nilai kosong (0) adalah negara yang paling korup dan nilai seratur (100)merupakan negara  yang dipersepsikan tidak melakukan korupsi, maka masih perlu untuk di tingkatkan. Berbagai cara harus dilakukan untuk memberantas dan mencegah korupsi di Indonesia, baik melalui jalur penegakan peraturan, jalur penegakan etika (moral dan iman), jaluir pendidikan dan jalur sosio-kultural. Hanya dengan segala upaya dan semangat juang yang tinggi, Indonesia segera terbebas dari korupsi.

This research is a qualitative descriptive study using data from the results of need assessment and the design of the initial phase model. Need assessment is needed to identify and map the symptoms of climate change in two research locations and how fishermen map existing institutions. The data are then used to formulate the initial model of institutional capacity for fishermen. The conclusions from the first year research are: (1) the understanding and knowledge of fishermen about climate change is relatively similar in two locations, namely empirical based on experience and pragmatic based on the characteristics of weather anomalies; (2) With a relatively low educational background, work ethic and a certain degree of rationality and efficiency for survival, fishermen in both research locations have a certain capacity to deal with climate change problems by building social relations, culture, community relations and their habitat; (3) fishermen make a relatively similar pattern of adaptation, namely changing professions temporarily, but still as a fisherman is the main job; (4) there are institutional arrangements in both locations consisting of government institutions (vertical institutions and regional offices), semi-official institutions, and fishermen groups or associations that are related to budget allocations and programs; (5) local institutions in both research locations have sought to increase their capacity through training, direct assistance or regional fisheries management programs so that fisheries resource management can be carried out sustainably; (6) general components that must exist in the initial institutional capacity. The model of the institutional improvement of fishermen consists of the development of human resources, business opportunities, improvement of resource management and environmental improvement carried out in an integrated and synergistic manner.Keywords: Capacity building, fishermen institutions, adaptation patterns, climate change, initial models
