hanya sebagai tanaman tumpangsari. Penanaman belum dilakukan dalam skala luas, namun untuk tumpangsari, produksi kacang komak bisa mencapai 1,5 ton per hektar. Keistimewaan dari kacang komak adalah mengandung antioksidan 10 kali lipat dari asam askorbat, bersifat hipo‐kolesterol dan hipoglikemik. Kacang komak mempunyai kadar protein cukup tinggi dan komposisi asam amino yang baik sehingga berpotensi untuk mengatasi kekurangan protein. Namun saat ini, pengolahan kacang-kacangan menjadi pangan fungsional sebagai sumber protein alternatif dan produk yang bernilai ekonomi tinggi masih sangat kurang. Permasalahan lainnya yang terjadi di masyarakat (mitra) adalah masih ditemukannya status stunting dan gizi buruk. Salah satu penyebab terjadinya stunting dan gizi buruk adalah kurangnya pengetahuan masyarakat dan sosial ekonomi masyarakat. Selain itu, meningkatnya jumlah pengangguran pada kondisi pandemi saat ini juga menjadi masalah yang terjadi pada mitra. Solusi yang ditawarkan pada program pengabdian ini adalah penyuluhan tentang kandungan nilai gizi dari kacang-kacangan, pelatihan pengolahan kacang lokal Lombok menjadi pangan fungsional sebagai sumber protein  alternatif dan dapat menjadi produk bernilai ekonomi tinggi, serta penyuluhan tentang pengemasan produk pangan.

Published: November 2021

Banyak sekali peluang berbagai media pembelajaran bagi para guru. Akan tetapi, sangat disayangkan peluang-peluang belum banyak dimanfaatkan oleh guru termasuk media video pembelajaran. Keluhan tidak bisa membuat masih saja menjadi hambatan bagi guru untuk menangkap peluang-peluang tersebut, sehingga pengembangan diri dan karirnya berjalan tidak seperti yang diharapkan. Munculnya keluhan tidak bisa membuat video pembelajaran di kalangan guru tentu saja bukan tanpa sebab. Secara umum ada beberapa kendala yang bisa ditemukan sehingga membuat tingkat partisipasi  dalam membuat media pembelajran dikalangan guru ini rendah. Di antaranya rendahnya minat membaca dan menulis, keterbatasan bahan bacaan yang bisa menjadi bahan tulisan, tidak adanya rasa percaya diri, ketidakpahaman guru atas bekal-bekal keilmuan untuk bisa terampil menulis, rendahnya motivasi untuk menulis, minimnya sarana untuk menuangkan ide dan gagasan dalam bentuk jurnal ilmiah.Target yang ingin dicapai dalam pelatihan ini adalah guru SD di Gugus V Kecamatan Batukliang Utara dapat memiliki pemahaman yang baik tentang media pembelajaran khususnya media Video, sebagai media dalam menelurkan ide-ide kreatif, terampil dalam menentukan tema menarik, menguasai langkah membuat video pembelajaran. Metode pelaksanaan dilakukan dengan menjelaskan konsep media pembelajaran, media visual dan media audio visual, mengembangkan media yang menarik khususnya tentang pendidikan, mendemonstrasikan dan menampilkan media audio visual pembelajaran serta memberikan pendampingan kepada peserta. Selanjutnya setelah peserta menyelesaikan membuat media, guru kemudia sosialisasikan kepada peserta didik untuk dapat digunakan. Hasil kegiatan pelatihan ini menunjukkan bahwa para peserta (guru-guru dari Kecamatan Batukliang Utara Kabupaten Lombok Tengah) memberikan sambutan positif terhadap materi yang diberikan. Hal ini terlihat dari antusiasme dan partisipasi aktif mereka terhadap materi dan tugas-tugas yang diberikan selama kegiatan berlangsung. Hal tersebut Nampak dari konsistensi peserta dalam mengikuti seluruh rangkaian kegiatan hingga akhir.  Bahkan, semua peserta mengharapkan agar dilakukan kegiatan serupa secara berkelanjutan. Semua guru dari Kecamatan Batukliang Utara yang menjadi peserta berhasil membuat satu contoh media audio visual untuk digunakan dalam pembelajaran yang disesuaikan dengan materi dan kurikulum yang sedang berjalan saat ini. Namun demikian, masih ada peserta yang belum selesai sepenuhnya dalam pembuatan media audio visual dikarenakan keterbatasan waktu dan kendala yang dihadapai saat pelaksanaan PPM, dan factor lain adalah kemampuan peserta berbeda beda dalam mengoperasikan computer dan internet dan aplikasi Camtasia Studio 7. Hal ini menunjukkan bahwa masih perlu memberikan penyuluhan secara lebih intensif kepada guru-guru dalam mengembangkan perangkat pembelajran khususnya perangkat pembelajaran yang mengarah kepada penggunaan Media Audio Visual.

Published: November 2021

Kinetics models are very vital to dumpsite operators and planners as they provide relevant information for effective treatment of leachates. The aim of this work is to model the kinetic process of treatment of Lagos dumpsite leachate using Musa sapientum peels as bio-sorbent with a view of establishing the kinetic parameters of the treatment process. Musa sapientum peels which were collected from Ayetoro market in Epe Local Government area of Lagos State were used to prepare the bio-sorbent. Kinetic process was carried out using 1 g of the prepared bio-sorbent in 100 ml Lagos dumpsite leachate in different conical flasks and at various contacting time. The kinetic data obtained were fitted to different kinetics models. The kinetics models tested were Fractional power model, Lagregren pseudo first – order model, Pseudo second – order model, Kuo – Lotse kinetic model, Blanchard kinetic model and Elovich kinetic model. Other kinetics models considered were Sobkowsk – Czerwi kinetic model, Intraparticle diffusion (IPD) model, Behnajady – Modirshahla – Ghanbery (BMG) model and Diffusion – Chemisorption model. Coefficient of determination (R2) values and the expected nature of the plots of the models were used to screen the tested models. The results revealed that the Pseudo second – order kinetic model has the best R2 value of 0.99996 and the graph followed the expected nature of the plot hence it was adopted in this work. It was concluded that Pseudo second – order kinetic model can be used to navigate the treatment process of Lagos dumpsite using Musa sapientum peels as bio-sorbent.

Published: November 2021

Good quality and economical availability of fodder could be a substitute for crop production in the farming system of dryland areas. In Pakistan, the increasing demands of fodder crops for animal feed require immediate attention to find viable options for fodder production. Additionally, climate change, land detritions, and imbalanced use of chemicals led to an agro-ecological imbalance which needs to focus on mitigation strategies and practices. Therefore, the experiment was conducted three different rainfed areas of Punjab with aims to increase fodder maize quality by application of Gibberellic acid (GA3) and Selenium (Se) to overcome the forage scarcity issue in rainfed areas. The highest fresh biomass and leaf area were recorded by the application of GA75+Se0.75 followed by GA50+Se0.50 at 60 DAS. Similarly, the data about the silage quality traits indicated that more total dry matter (TDM), TDN, Crude protein (CP), neutral detergent fiber (NDF), Crude fiber (CF), acid detergent fiber (ADF), ash contents (AC) were recorded in Afgoi compared to Sohni Dhart 623. Among the experimental locations, the highest TDM, TDN, NDF, ADF and AC were found for the crop planted at NARC followed by URF, Koont and the least values of these traits were recorded for GRS, Attock. Among the different combinations of growth regulators, the highest TDM, TDN, CF, CP and NDF were recorded for GA75+Se0.75 followed by GA50+Se0.50. The above findings conclude that exogenously application of GA75+Se0.75 plays a promising role in the improvement of fodder growth and quality parameters of silage in Afgoi verity at different water stress agro-ecological zones.

Authors: Ismail Abdi
Published: November 2021

Kajian teknis berupa analisis kekuatan dan berat struktur antara struktur lambung konvensional dan lambung dengan material sandwich dilakukan pada kapal tanker 17500 DWT menggunakan metode elemen hingga. Fiberglass reinforced polyurethane elastomer (FRPU) digunakan sebagai core dari material sandwich kapal tanker dan baja digunakan sebagai material dari faceplate. Pada model struktur lambung konvensional tegangan maksimum yang terjadi adalah 83.5 MPa, sedangkan model struktur lambung sandwich menghasilkan tegangan maksimum sebesar 84.5 MPa. Struktur lambung konvensional maupun struktur lambung material sandwich memenuhi kriteria, karena kedua model memiliki tegangan jauh dibawah batas tegangan yang diizinkan yaitu 235 MPa. Selain itu, penerapan material sandwich menghasilkan kenaikan tegangan yang sangat kecil, yaitu sebesar 1 MPa atau setara dengan 1.2%, tetapi menghasilkan pengurangan berat sebesar 3 ton atau 6.2% dibandingkan dengan struktur konvensional. Penerapan material sandwich dapat mengurangi berat konstruksi kapal, sehingga tanker dapat mengangkut muatan lebih banyak dan operasional kapal dalam sekali perjalanan akan lebih ekonomis. Dengan demikian, pengembangan material ringan kapal diharapkan mampu menunjuang kualitas operasional kapal dan diharapkan mampu meningkatkan daya saing kapal tanker nasional.

Published: November 2021

Oyster mushroom is one type of vegetable that is rarely utilized due to a lack of knowledge about how to process the mushroom itself. The perishable nature of mushrooms causes difficulties in distribution and marketing as fresh produce. One of the processed products from oyster mushrooms is chips. Vacuum frying is a frying method that is applied to heat-sensitive materials such as fruits and vegetables. This study was aimed to determine the effect of temperature and duration of vacuum frying on the physicochemical and organoleptic qualities of oyster mushroom chips. The study was conducted using a completely randomized design with a two-factor factorial pattern: the first factor, vacuum frying with a temperature of 85o and 90oC. The second factor, frying time, is 50, 60, and 70 minutes. The results showed that vacuum-fried oyster mushrooms with a temperature of 85oC and a frying time of 70 minutes produced oyster mushroom chips with the lowest fat content of 38.08%, the preferred taste, and color (score 4), while the preferred texture was frying at 90oC and long 70 minutes. The yield value and moisture content of oyster mushroom chips did not differ at different temperatures and frying times.

De la Grande Arménie à la Cilicie, voyager dans le monde arménien médiéval (XIe-XIVe siècle)
Authors: Augé Isabelle
Published: November 2021

During the medieval period, the Armenian world was composed of two major poles, Great Armenia, which fell under Seljuk domination, and Cilicia, a principality, then an Armenian kingdom. Contacts continued between these two areas, particularly on a religious level. Armenian Christianity remained unified, and meetings of bishops were, for example, the source of trips, embassies and councils. In the same way, the Catholicos sends letters to all Christians, through the intermediary of emissaries who travel from one place to another. Cultural Contacts continue, with the circulation of manuscripts between Great Armenia and Cilicia.
Trespassing Boundaries in Wuthering Heights
Geographical and Environmental Perspectives
Authors: Brazzelli Nicoletta
Published: November 2021

The Spatial Turn as a transdisciplinary phenomenon in the Humanities was established in the 1990s, and, especially in the last few decades, geography seems to have pervaded critical analysis and language. According to contemporary geographical and environmental perspectives, the setting in narratives is not only a background defining the place where the plot is located but a complex system that is central to the construction of literary texts. Wuthering Heights (1847) provides an excellent case study. Emily Brontë’s novel is certainly characterized by its topography. Although different sources had been collected by the writer from a wide range of models across the country in Yorkshire, they were then reassembled to form a landscape that is both familiar and uncanny, self-consistent and reminiscent of real buildings and sceneries. Besides, the dynamics between displacement, departures and arrivals and the seeming immobility of the landscape is a crucial pattern of the novel. In Wuthering Heights, the natural world of the moors and its geographies are reminders of history and memory. Brontë’s weaving together of emotional stories into the moorlands suggests a mutual exchange between nature and culture. The writer constructs a textured geography representing the cycles of change, family history, and passion that have created that space.
The Revolutionary Intertextuality of Molora by Yäel Farber
Authors: Zinato Susanna
Published: November 2021

This article focuses on the challenging intertextual phenomenology characterising the play Molora by South African playwright and director of international acclaim Yäel Farber. Premiered in Grahamstown in 2003, and published in 2008 after award-winning national and international tours, Molora is a radical adaptation of Aeschylus’ Oresteia. It dramatises the challenges faced by South Africa in the highly-charged post-Apartheid aftermath, through dramatic confrontations between Klytemnestra, Elektra, and Orestes echoing the testimonies delivered by perpetrators and victims on the TRC’s ‘stage’, and through a chorus made up of seven Xhosa matriarchs belonging to the Ngquoko split-tone singers, who witness, comment on and significantly participate in the play’s action. Molora’s complex intertextual construction and dynamic are shown to call for a hermeneutical approach careful to avoid simplifying presentifications, as well as any possible fracture with extratextuality. Intertextuality, in fact, is here given the task to creatively and syncretically combine the ancient Greek text with the indigenous Xhosa text through a process of transcultural imbrication that, from beginning to end, exudes the tragedies of all-too-present history while instantiating a revolutionary use of memory.

Improving the reliability, durability and safety of operation of heavily loaded friction units is an urgent problem in physics, chemistry and surface mechanics. The tribotechnical characteristics of coatings made of bronzes BrAZhMts10-3-1.5 and BrMtsF3-6, applied by electrospark alloying on bushings made of structural steel 30KhGSN2A for operation under conditions of high contact pressure under friction without lubrication, have been investigated. Modes of coating deposition from the standpoint of tribology (the value of the electric discharge current in a pulse, the value of the longitudinal electrode feed per one rotation of the part, the rotation speed of the workpiece, the number of passes during processing, finishing of the coating) have been developed. It was found that when applying bronze BrMtsF3-6 to obtain a high-quality coating, the process must be performed in a protective atmosphere of argon to prevent phosphorus burnout. The tribotechnical efficiency of coatings when working under dry friction conditions is shown. For the steady-state wear mode, the friction coefficient is 0.10 – 0.13 at a pressure of 200 – 250 MPa, the wear resistance of coated steel is doubled. Steel with a bronze coating BrAZhMts10-3-1.5 has a higher bearing capacity, with BrMtsF3-6 coating — a higher antifriction. The ways of increasing the service life of steel-coated steel friction pair are analyzed.

Silumins are promising antifriction alloys for the manufacture of friction units. They have a low density, high wear and corrosion resistance. However, they own low hardness and strength, which leads to the need to develop modifying and strengthening additives. Aluminosilicates have a density close to silumin and can be used for its strengthening, but they are characterized by low wettability by metals. To improve wettability, it is necessary to modify the aluminosilicates with metals. The aim of this work is to study the mechanochemical synthesis of aluminosilicate/Nickel composites and modification of silumin using them. Structural changes in powder mixtures of natural aluminosilicates with Nickel during high-energy mechanical processing in a planetary ball mill, as well as in alloys of the composition silumin + potassium fluoroborate and silumin + potassium fluoroborate + aluminosilicate/Nickel obtained by hot pressing of mechanoactivated powders, were studied using Fourier-infrared spectroscopy and x-ray diffraction analysis. It is shown that mechanical activation of a mixture of silumin + potassium fluoroborate powders leads to a redistribution of silicon during sintering with the formation of large primary silicon crystals and a decrease in micro hardness by ~ 20 %. Mechanical activation of aluminosilicates with Nickel leads to the formation of composite powders with the removal of OH groups and the formation of SiO2 framework structures. The use of such a modifier during sintering of the silumin alloy leads to the formation of a homogeneous fine structure of the alloy with the grinding of eutectic and primary silicon grains, which increases the micro hardness of the alloy by 1.5 times.

The influence of the concentration of finely dispersed aluminum and compatibilizer on the resistance to peeling of aluminum foil from the surface of a composite based on low density polyethylene and high density polyethylene is considered. To improve the compatibility of the filler with the polymer matrix, a compatibilizer was used, which is a graft copolymer of polyethylene of various grades with methacrylic acid and maleic anhydride. Copper and aluminum foil was used as a substrate. It is shown that the introduction of a compatibilizer into the composition of aluminum-filled composites improves their peeling resistance. It has been found that if an aluminum filled compatibilizer is used directly as an adhesive, then the peeling resistance of copper and aluminum foil is significantly increased. Graft copolymers of polyethylene with maleic anhydride have the highest peel resistance values. The results of the study of the influence of the pressing temperature on the type of adhesive failure are presented. It is shown that with an increase in the pressing temperature, a mixed type of adhesive destruction is observed. It has been experimentally proved that, in percentage terms, the cohesive type of fracture prevails in composites where graft copolymers are used as a polymer matrix. It was found that a 100 % cohesive type of fracture is observed in foil-clad composites pressed at a temperature of 190 °C, where a graft copolymer of polyethylene with methacrylic acid or maleic anhydride is used as an adhesive.

The results of an AFM study of changes in the surface structure of K-208 and CMG cover glasses after electron irradiation and exposure to molecular fluxes are presented. It is shown that contamination of glass surfaces irradiated with electrons at flux densities (φ) from 1010 to 8·1010 cm–2 s–1 occurs during electrostatic discharges accompanied by the release of plasmoids into the surrounding space, the particles of which are deposited on the glass. It has been experimentally established that the effect of preliminary irradiation of glass on the deposition of molecular flow components is most effective immediately after irradiation and decreases with time. This is due to the drainage of the charge injected into the glass and a decrease in the initially high reactivity of the substances in the discharge channels. It was also shown that the combined effect of electrons and molecular flux on glasses significantly increased the discharge frequency at a given value of φ and, as a result, led to an increase in the number of discharge channels on the sample surfaces. In this case, over time, the process of accumulation of molecular flow components begins to dominate the cleaning of the glass surface due to electron-stimulated desorption and mechanical desorption under the action of shock waves accompanying the discharges. To interpret the experimental results, a mathematical model of the deposition of molecular flow components on glass is proposed.

Chemical and granulometric analysis of AlSi10Mg alloy powder was carried out. It was found that the powder particles are generally non-spherical, with a significant number of inclusions in the form of satellites. Particle size distribution ranges from 5 to 60 μm. The presence of conglomerates up to 70 μm in size is observed. The study of the influence of scanning parameters on the tensile strength and relative elongation of the samples has been carried out. It was found that in the range of the scanning speed range of 910 – 930 mm/s, local mechanical minima are observed. In order to optimize the scanning parameters, complex quality indicators are used. The greatest desirability from the point of view of obtaining the maximum strength and plasticity of the material is a combination of scanning parameters: laser power — 350 W, scanning step — 0.19 mm, scanning speed — 980 mm/s, with a layer thickness of 50 μm. The results of tests of cylindrical specimens made at angles of 0° and 90° relative to the construction platform are presented.

The results of the analysis of damageability and modification of the structural-phase state of the surface layers of aluminum and its alloys by powerful flows of fast high-energy ions and high-temperature plasma in Plasma focus devices, as well as using pulsed laser radiation. Pure Al, an alloy of the Al – Mg – Li system, a duralumin alloy, and a composition of a ceramic coating Al2O3 on an Al substrate are considered. It is shown that in the regime of Al irradiation with a power density of q ≈ 106 – 107 W/cm2 in the nano- and microsecond range of pulse durations, ultrafast crystallization of melted surface layer occurs with the formation of a wavy surface relief and the structural fragments of sub-microcrystalline and nanoscale size. After the action of deuterium plasma flows on a duralumin alloy tube located along the axis of the Plasma focus device a modification of the structural-phase state of the alloy is observed: the initial two-phase state of an αAl-solid solution of copper in aluminum and inclusions of the second phase of CuAl2 became fine-grained and single-phase due to the dissolution of CuAl2 particles in the melt. Irradiation of an alloy of the Al – Mg – Li system containing (wt %) 2 % Li and 5 % Mg at q = 5·106 W/cm2, t = 50 – 100 ns after four pulsed impacts of fast ions and deuterium plasma led to the modification the structural-phase state of the surface layer of the alloy, associated with an increase in the content of magnesium oxide and a decrease in the crystal lattice parameter of the Al-based solid solution. The formation of spherical cavities due to the evaporation of lithium into the internal micropores of the surface layer was also found. The low damage and structural stability of Al2O3 ceramics on an Al substrate under beam-plasma impacts in plasma focus device with a radiation power density q ≤ 108 – 109 W/cm2 in the nano- and microsecond range of pulse duration is noted. At the same time, the Al2O3/Al composition was unstable to pulsed laser radiation in the free-running mode (q = 105 – 106 W/cm2, t = 0.7 ms) and Q-switch mode (q = 107 – 108 W/cm2, t = 80 ns). In both cases the coating peeled off from the substrate.

A new hybrid carbon-hydrocarbon structure was discovered after pumping a gas mixture of methane and hydrogen through 314 – 400 µm synthetic diamond powder. The experiment was carried out on the microwave plasmachemical installation designed for deposition of polycrystalline diamond films. The main parameters during the experiment were the following: the power of the microwave generator 3,5 kW, the flow rate of hydrogen 400 ml/min, methane 20 ml/min, the pressure in the reactor chamber 63 torr. The gas mixture was pumped at pressure drop of 13 torr. The diamond powders were placed in molybdenum cups inserted into a copper pedestal. In the gaps between the diamond particles of the surface layer unidirectional thread-like structures (length 100 – 500 μm, diameter 2 μm) were found, some of which ended in spherical formations (average diameter 18 μm). Such a composition of thread-like structures and spherical formations was called “dandelion” one. Raman spectroscopy was performed to examine the nature of these formations. The thread-like structure was determined as monocrystalline graphite. The surface of the spherical formation was represented by spindle-shaped structures of nanocrystalline graphite (length 2 μm, thickness 200 nm) and nanodiamond grains with trans-polyacetylene chains [C2H2]n.

Wireless Fidelity (Wifi) merupakan salah satu bentuk perkembangan dari teknologi koneksi tanpa kabel dengan menggunakan gelombang radio. Penggunaan Wifi sekarang ini sudah sangat lazim kita jumpai dimana-mana baik itu ruang publik seperti taman sampai ruang privat seperti rumah dan kantor. Salah satu keunggulan menggunakan jaringan Wifi adalah satu titik Hotspot (Wifi) bisa digunakan oleh beberapa perangkat device berbeda. Karena kepraktisan inilah banyak dari masyarakat sekarang yang menggunakan Wifi untuk berkegiatan sehari-hari seperti membaca berita, membuka social media, sampai keperluan pekerjaan dan pendidikan. Namun didapati bahwa  masih banyak masyarakat yang belum bisa menikmati fasilitas Wifi ini dikarenakan setiap pemasangan titik Hotspot (Wifi) diperlukan biaya yang tidak murah dan setiap bulannya memerlukan biaya berlangganan. Untuk hal tersebut, perancangan program pengajuan wifi publik kota Depok dibuat dengan tujuan agar mempermudah masyarakat dalam mengajukan pemasangan Wifi karena bisa dilakukan secara online serta dengan tujuan lainnya yaitu agar masyarakat khususnya kota Depok dapat mengetahui mengenai informasi terkait lokasi yang sudah tersedia Wifi. Metode penelitian yang digunakan dengan metode waterfall  dengan model pengembangan SDLC. Pengumpulan data dilakukan dengan wawancara, survey dan observasi. Alat Bantu analisis menggunakan Entity Relationship Diagram  dan Logical Record Structure (LRS). Diharapkan dengan adanya aplikasi ini masyarakat khususnya warga Depok dapat dengan mudah mendapatkan pelayanan Wifi gratis antara lain untuk tempat-tempat seperti taman, balai warga, posyandu, tempat ibadah, kantor Rukun Warga, dan lain-lainnya dengan cara pemasangan wifi gratis pada area-area tersebut.

Military-industrial complexes of many countries have invested billions of dollars in the industry over 120 years of development and have achieved significant progresses in the creation of surface, water and underwater equipment. Groups of military unmanned vehicles include unmanned aerial vehicles (UAVs), deck-based UAVs, water, underwater and hybrid unmanned vehicles (UAVs). Their purpose is intelligence, surveillance, strategic research projects, and military transport purposes. As for the civilian use of unmanned vehicles, this is a young industry, it is 15 years old. The beginning of the era of non-military unmanned aerial vehicles (UAVs) and then unmanned floating vehicles (UAVs) is considered to be 2006, when the US Federal Aviation Administration allowed the flights of small custom drones. At the same time, they were given a definition: a device that is remotely controlled by an operator; a device that moves along a pre-planned route. Unmanned vehicles the use of which for the purposes of the forest complex of our country is carried out or is planned to begin in the near future must meet some special requirements that are discussed in this article.
