Authors: Reza Izzul Fatchu , Andriani Sarah Putri
Published: August 2019

Seiring berubahnya waktu, masyarakat di desa Hanura tidak dapat menghasilkan makanan sendiri secara mandiri untuk memenuhi kebutuhan sehari-hari. Hal ini karena mayoritas masyarakat Hanura bekerja sebagai non-petani dan keberadaan pasar justru memudahkan mereka untuk mendapatkan akses untuk memenuhi kebutuhan sehari-hari mereka. Oleh karena itu, pemerintah desa Hanura melakukan inovasi dengan menerapkan Program Rumah-Kaca untuk meningkatkan ketahanan pangan masyarakat dengan menciptakan kesadaran masyarakat untuk menghasilkan makanan secara mandiri. Pencapaian Program Rumah-Kaca sebagai media pembelajaran gerakan dan produksi makanan secara mandiri terhadap masyarakat, hal ini membuat peneliti penasaran untuk mengetahui seberapa jauh efektivitas Program Rumah-Kaca sebagai upaya meningkatkan ketahanan pangan masyarakat di desa Hanura, Kecamatan Teluk Pandan, Kabupaten Pesawaran. Penelitian ini merupakan penelitian kualitatif. Teknik wawancara, observasi dan dokumentasi diadministrasikan sebagai data pengumpulan tehnik penelitian. Hasilnya menunjukkan bahwa Program Rumah-Kaca dalam meningkatkan ketahanan pangan masyarakat desa Hanura belum berjalan efektif karena ada kekurangan sumber daya manusia yang dapat mengikuti Program Rumah-Kaca dan jumlah output pangan di Program Rumah-Kaca belum memadai untuk keseluruhan kebutuhan masyarakat desa Hanura. Implementasi Program Rumah-Kaca pemerintah desa Hanura mengalami kendala yaitu kurangnya kesadaran masyarakat untuk mengambil bagian, iklim yang menghambat pertumbuhan tanaman di Rumah-Kaca dan banyak pedagang pedalaman bebas dalam menjual makanan instan yang berlawanan dengan tujuan Program Rumah-Kaca

Published: August 2019

Genetik beronang (Siganus) dan cobia (Ranchycentron canadum) dari Indonesia dan Taiwan dibandingkan keragamannya. Beronang merupakan komoditas penangkapan dan cobia merupakan komoditas budidaya di Indonesia yang diduga berasal dari Taiwan. Penelitian ini bertujuan untuk membandingkan keragaman genetik kedua jenis ikan sebagai rujukan untuk pengembangan konservasi atau budidayanya. Metode sidik jari DNA dengan AFLP (amplified fragment length polymorphism) dengan dua primer digunakan untuk mempelajari keragaman genetiknya. Multivariat analisis digunakan untuk menghitung statistik keragaman  populasi dari karakter fragment DNA dari AFLP. Hasil penelitian menunjukkan terdapat dua spesies beronang yang berbeda dari hasil tangkapan di sekitar Teluk Hurun Lampung yaitu Siganus fuscescens dan S.gutattus. Hasil penelitian lebih mendalam menunjukkan bahwa beronang yang berasal dari Taiwan sangat berbeda dengan Indonesia yang ditunjukkan dengan jarak genetik yang jauh. Hal ini menandakan nenek moyang beronang ini tidak sama dan tidak memiliki hubungan. Hasil berbeda diperoleh dari cobia, dimana populasi  Taiwan terpisah menjadi dua grup dan sebagian besar cobia dari Indonesia bergabung didalam satu grup populasi Taiwan dan sebagian kecil membentuk stok khusus yang berbeda. Hal ini menunjukkan bahwa populasi cobia Indonesia merupakan sebagian kecil dari populasi cobia Taiwan. Penelitian memberikan rekomendasi bahwa populasi beronang dari Indonesia masih asli dan layak secara genetik untuk dikembangkan sebagai komoditas budidaya. Populasi cobia budidaya dari Indonesia merupakan sebagian kecil populasi cobia budidaya Taiwan sehingga jika menghadapi masalah inbreeding dapat memanfaatkan karakter genetis lain dari populasi Taiwan tersebut.

Authors: Yusmiati Yusmiati , Singgih Bambang
Published: August 2019

Limbah ternak dapat menurunkan kualitas lingkungan apabila tidak dikelola dengan baik, dilain pihak limbah ternak dapat diolah menjadi sumber energi yang dapat dimanfaatkan oleh rumah tangga. Limbah ternak diolah menjadi biogas dengan proses fermentasi anaerobik. Biogas adalah salah satu energi terbarukan dan ramah lingkungan. Energi biogas dapat diperoleh dari air buangan rumah tangga; kotoran cair dari peternakan ayam, sapi, babi; sampah organik dari pasar; industri makanan dan sebagainya. Untuk mengubah limbah ternak menjadi biogas dibutuhkan serangkaian alat yang disebut reaktor biogas. Penggunaan sistem reaktor biogas memiliki keuntungan, antara lain yaitu mengurangi efek gas rumah kaca, mengurangi bau yang tidak sedap, mencegah penyebaran penyakit, panas, daya (mekanis/listrik) dan hasil samping berupa pupuk padat dan cair. Reaktor biogas terbagi menjadi tiga tipe yaitu tipe terapung, tipe kubah tetap, dan tipe balon. Tipe reaktor biogas yang direkomendasikan untuk pengolahan biogas limbah ternak adalah reaktor tipe kubah tetap (fixed dome) karena memiliki keunggulan diantaranya adalah biaya konstruksi lebih murah daripada reaktor terapung, bisa dikerjakan sendiri oleh peternak, lebih tahan lama dibanding reaktor tipe balon, serta perawatannya lebih mudah.

Authors: Kumar Ch. Aravind
Published: August 2019

Currently, we are proceeding towards the 5th generationof wireless networks. The 5G is expected to utilize verywide bandwidth and would have the greater capacity comparedto 4G. Therefore, the energy efficiency is one of the prominentroles in the design criterion. To achieve the maximum energyefficiency, the typical approaches are to increase the throughputor to decrease the power consumption. Recently, the approachto combine the small cell access points to Massive MIMO hasbeen proved as one efficient way to achieve the maximum energyefficiency. In this work, the approach to combine two typeof network, namely Small Cell Access Point (SCA) and BaseStation (BS) with Massive MIMO, is considered for designing anenergy efficient system. We investigate further this approach byextending the simulation to cover both 3GPP LTE as well as IMT2020 environment with two different carrier frequencies underthree scenarios. The performance is measured and comparedwith the existing work in terms of total power consumptionper subcarrier of both the Base Station (BS) and Small CellAccess Points (SCAs). It is apparent that our proposed methodprovides the higher information rate at the same total powerper sub carrier than the existing work. Additionally, generalspeaking, the 3GPP path loss model provides the lower totalpower consumption per sub carrier at BS than IMT-2020, whileboth path loss models almost has no impact on total powerconsumption at SCAs, regardless of carrier frequency and thenumber of antennas adopted in Massive MIMO at BS.

Detecting Planets from Direct-imaging Observations Using Common Spatial Pattern Filtering
Authors: Shapiro Jacob , Savransky Dmitry , Ruffio Jean-Baptiste , Ranganathan Nikhil , Macintosh Bruce
Published: August 2019

We present the application of common spatial pattern (CSP) filtering to the detection of point sources in high-contrast astronomical images. The data are preprocessed in two different ways: one copy of the data set keeps the point source in the same spatial location over many images through time, while a second copy of the data set moves the point source azimuthally through the image as in angular differential imaging. The differences between these two data sets are exploited via CSP filtering, highlighting the point source. We develop a forward model for this new process, which is then used to predict the result of applying this method to data with a point source at a particular spatial location. We validate the forward model numerically and use the prediction as template in a matched filter with the actual CSP modes. We present results for multiple sets of observational data and show that the new CSP forward model matched filter (FMMF) can compare favorably to the state-of-the-art Karhunen–Loève image processing FMMF reduction in terms of signal-to-noise ratio and unfavorably in other metrics.

Published: August 2019

Remote laboratories are important in education because they provide access to equipment that some institutions cannot afford to purchase or maintain, reduce the need for dedicated physical space for equipment and personnel to staff laboratories. But more than just fill the absence of real physical laboratories; remote laboratories can improve the users experience through the use of adaptive and specific. An important element in supporting shared access is coordinating the scheduling of the laboratory usage. Optimized scheduling can significantly decrease access waiting times and improve the utilization level of remote laboratories resources, with associated reductions in per-use costs.The user management systems that exist so far are limited, and not compatible with all remote lab interface development software. For that, we worked on the development of a new user management system for remote laboratories.This paper proposes a model and set of diagrams that define the new reservation system and a new Queuing for remote laboratories for educational purposes.

Authors: Alnsour Muhammed , Al Faour Hadeel Rakan
Published: August 2019

The purpose of this article is to study the relationships between brand community engagement of customers on social media networks and customer behavioral intentions with regard to visiting restaurants where the theory of planned behavior was applied. A conclusive-descriptive, cross-sectional research design was selected in order to determine the degree to which Brand Community Engagement, Attitude (ATT), Subjective Norms (SN), Perceived Behavioral Control (PBC), Restaurant's Visit Intentions (INT) and Visit Behavior (B) are interrelated and associated. The results indicated that BCE does affect customers attitude towards dining out and visiting restaurants and that SN cannot moderate the strong relationship between ATT and intention. In addition, customer intention can weakly predict their behavior of visiting restaurants. The results of this study suggest that management of restaurants should pay attention to their marketing communication strategies through social media restaurant's communities and should focus on how to increase the engagement levels of customers beside understanding and may be changing their attitudes towards experiences in restaurants. This study examined the relationship between Restaurants Brand Community Engagement on social media and customer intentions to dine out and visit restaurants.

Load-Balance Energy Aware Ad-Hoc On Demand Multipath Distance Vector Routing Protocol (LBEA-AOMDV) for WSN
Authors: Sarhan Amany , El-Fishawy Nawal A. , Shawara Mahmoud M.
Published: August 2019

Nowadays, WSNs have received great importance because they are the best solutions that can be used in harsh environments. The main limitation in WSNs is the node power because the sensor node is battery powered and charging or replacing this battery is not applicable. Moreover, in mission-critical applications, sensor nodes can sense important data and the packet carrying this data must be given higher priority from the routing protocol. Most of the current routing protocols consider the node power but do not consider different paths for different priority data which may cause them to be delayed. This article proposes a load-balance energy aware ad-hoc on demand multipath distance vector (LBEA-AOMDV) protocol for wireless sensor networks, which is a multipath routing protocol, based on the original AOMDV. The proposed protocol shows that the paths are alternatively discovered on basis of an energy metric and instead of using only one path in data transmission, the network load is distributed through different paths. LBEA-AOMDV also uses a priority-based technique in which packets are assigned different priority levels and guided to different paths. The overall simulation results show that LBEA-AOMDV gives better performance when compared with AOMDV in terms of average consumed energy, end-to-end delay, number of dropped packets, average throughput and normalized routing load.
Dynamic Elasto-Plastic Analysis of a Hybrid Coupled Wall System
Authors: Shi Yun , Zhang Yu Min , Weng Guang Yuan , Dai Jian Bo
Published: August 2019

In a hybrid coupled wall (HCW), a steel coupling beam with a good shear performance can replace a concrete coupling beam. This is especially applicable for locations in which height restrictions do not permit the use of deep reinforced concrete beams or in which it is not possible to economically develop required capacity, stiffness, or deformation demands with concrete beams. In this study, a new type of connection design with a steel boundary element of hybrid coupled wall (SBE-HCW) was proposed, and a 23-story SBE-HCW structure was analyzed under both gravity and seismic load to examine the seismic performance using ABAQUS. The structural failure process, base shear force, vertex displacement, and damage distribution of core tube were investigated. The analysis results confirmed that the response of specimen exhibited good plastic deformation behavior under seismic, thereby satisfying the demands of seismic ductility design. The connection between the steel coupling beams and the shear walls in the specimen appeared to be intact. The analysis evidence indicated that the proposed connection detailing appeared to be effective.

Carbonate Hydroxyapatite (CHAp) is one of biomaterial that can be synthesized from natural ingredients. CHAp has been successfully synthesized from pearl shells (Pinctada maxima) using the precipitation method. The pH of the synthesis process affects several characteristics of CHAp, including crystallinity, crystal size, morphology, and carbonate content. XRD data showed that CaO obtained from pearl shell powder through the calcination process. The highest crystallinity of CHAp occurs when the pH is 8, and the lowest is at pH 10. The size of the crystalline CHAp decreased when the pH increased. Based on SEM data, the morphology of CaO looks more tenuous than the morphology of CaCO3 due to CO2 release during the decomposition process. The magnitude of pH greatly influences the morphology of CHAp where morphology looks different for different pH. EDX data shows that CHAp has the highest carbonate content when pH 10 with a smaller Ca/P ratio when the carbonate content gets bigger.

In this work, a novel type of δ-TRIP steel was designed, and the content and stability of retained austenite in δ-TRIP specimens under different annealing processes were detected and studied, respectively. The volume fraction of austenite was determined by X-ray diffraction (XRD). The microstructure and mechanical properties were analyzed systematically. The results show that a complex microstructure composed of three phases (ferrite, bainite and retained austenite) was obtained in the δ-TRIP steel. With the increasing of annealing temperature, both retained austenite and bainite content in the specimen increased, while the carbon content in retained austenite decreased, leading to a poor stability for retained austenite. Both tensile and yield strength improved with the increasing of annealing temperature, while the elongation reduced. The feature of retained austenite led to an excellent combination of ductility and strength, which was better than traditional TRIP steel.

Concrete of used sewers is exposed to various aggressive environments. While making concrete pipes for special purposes, special attention is paid to reducing the permeability of the surface layer of concrete. It is possible to increase the operational characteristics of concrete by introducing into the cement system the active components chemically interacting with the cement minerals. When the complex modifier interacts with cement particles, the structure and properties of the modifier undergo qualitative changes. The article presents the results of researching the porosity of the modified cement matrix. It has been established that in the neoplasms of the modified cement matrix of concrete, the quantity of free calcium hydroxide does not exceed 5% that is a necessary condition for getting a corrosion-resistant material. As a result of the analysis of modern technologies, it has been established that physical modification is possible by removing excess mixing water that increases the use of the potential qualities of cement in order to increase the density, impermeability and strength of concrete in the process of compaction of the mixture.

This paper presents the research method of hardening process of gypsum binders and composites, based on them, using the ultrasonic method. Modern construction composites, based on higher water resistance gupsym, contain the coarse aggregate particles, giving them heat and sound insulating properties. One of the frequent purposes, designing such composites, is the slowdown of the processes of setting, so it allows the builders to work with the material for a sufficiently long period. The use of standard control penetration methods of the setting processes for the considered composites becomes difficult because of the presence of course particles in the binder paste. The ultrasonic method is proposed to use alternatively to study the process of setting. For its implementation, the technique has been developed, based on the use of ultrasound systems for quality control of concrete products. The transit time of ultrasonic signals through the layer of hardening binder paste with the fixed thickness was measured in a regular intervals until completely setting. On the basis of the obtained data, the ultrasound velocity was calculated and the setting time was determined. For this purpose, a differential curve of the time of ultrasound transmission was plotted, and the period was considered, at which the transition to the steady-state condition was carried out, it is equivalent to the end of the setting. The initial setting was determined by the first trip of the measuring equipment, corresponding moment of the formation of the primary crystal structure of the composite, which has sound-transmission properties. To verify the values of the setting time, the simultaneous measurement of the plastic strength of the model system was used. The moments of the beginning and the end of the setting, as well as the ultrasound velocities which were typical for these moments, were determined with the plastic strength. The obtained velocity values allowed to find the setting times of other composites. The actual setting time is estimated based on the values, obtained by all the available methods. The model, based on percolation theory, has been proposed for analyzing the physicochemical phenomena during the setting.

Experimental studies of the stress-strain state of reinforced concrete and fiber-reinforced concrete beams under short-term and long-term loads were carried out. The tests were carried out on three series of beams of different types - from ordinary concrete, steel fiber concrete and combined section, when the lower zone of the beam with a height of 0.5h is made of steel fiber concrete, and the upper one is made of ordinary concrete. During short-term loading, the load was applied in steps with a 10-minute exposure at each step to failure or to a predetermined level of a continuously acting load. In the interval between the steps, the process of cracking was tracked. After reaching a given level of loading, the load was fixed and maintained unchanged with a spring cassette for 300 days. Deformations were measured using strain gauges and dial gauges. Deflections and relative deformations of the extreme upper and extreme lower fibers for three types of beams are determined. It has been established that stabilization of deflections in beams from steel fiber concrete occurs much earlier (100 days) than in beams made of ordinary concrete (175 days). Studies have shown that the beams of ordinary concrete in the process of long-acting load lowered the carrying capacity by 5.5%. The bearing capacity of steel concrete beams, in contrast, increased by 7.6%.

Problem of heat insulation and reliability of enclosing structures of buildings is the current issue nowadays due to strict requirements thereto. Protection of exterior walls of autoclaved aerated concrete blocks against negative impacts may be achieved by waterproof plastering combining decorative function either, i.e. decorative and protective system. Such system is possessing hydrophobic properties protecting against inflow of rainwater and condensate accumulating in the wall surface during seasonal periods. Application of decorative and protective “Baumit” system has been tested in heat efficient walls of autoclaved aerated concrete blocks in the Republic of Bashkortostan. It has been found that after several years of operating the protective system revealed no failures, and the wall has proved to be reliable as to heat protection, indoor conditions and interior surface of the walls.
