El camino del ser. El arte como camino
Authors: Sánchez Aranegui Mónica D.
Published: April 2019

Vivemos num mundo em constante mudança, sem um guia que nos ajude a elaborar adequadamente toda a informação visual que consumimos ao longo do dia. Parar para refletir sobre o que vemos nos leva à construção do pensamento a partir da reflexão e integração. Da imagem à emoção, da emoção ao pensamento. Abandonar o estado passivo, deixando de relegar o ser a um segundo plano, no sentido de manifestar nossa própria essência como um caminho de descoberta e de própria evolução, para aprender, no sentido amplo da palavra, ao mesmo tempo que nos permita desaprender. Avançar, em todo caso, no processo de construção de nosso pensamento, dos valores que articulam nossos fundamentos como pessoas. Aquilo que é fundamental, que nos descreve e nos define, que nos faz ser como somos e não de outro modo.

Numerical simulation of the flow field structure of liquid nitrogen jet
Authors: Cai Chengzheng , Ren Keda , Li Qinghua
Published: April 2019

Liquid nitrogen jet is regarded as an excellent technology for the well drilling and reservoir fracturing. To evaluate the flow field structure of liquid nitrogen jet, a 2-D CFD model is established. The transient velocity and temperature fields of liquid nitrogen jet is simulated. The results show that the liquid nitrogen jet also clearly presented the velocity boundary and potential core region similar to the water jet. Given the temperature difference between the jet and surrounding fluid, the liquid nitrogen jet has an obvious temperature boundary, on which the jet temperature is equal to the initial value. According to the phase of the jet, the flow structure can be divided into the liquid nitrogen jet and non-liquid nitrogen jet regions. The temperature boundary shows a larger width than the velocity boundary for liquid nitrogen jet. Moreover, both width and length of the liquid nitrogen jet region are greater than the potential core region.
Analysis and correlation of fluid motions in natural thermal convection in a cylindrical vessel
Authors: Wang Wei , Guan Xin-Lei , Wang Li-Jun , Guo Chu-Wen
Published: April 2019

A natural thermal convection system is set up in a cylindrical vessel with aspect ratio of 2 having a temperature gradient in the vertical direction, and the fluid motions due to convection are investigated. The 2-D velocity field along the plane passing through the diameter of the vessel is obtained using particle image velocimetry. The results indicate that the convection is in the transition stage and the mean velocity fields show two pairs of counter-rotating circulations. The mean motions are predominant in the vertical direction under the influence of the temperature gradient, while the fluctuations in the x- and y-directions have the same order of magnitude. Probability density functions of fluctuation velocities at seven characteristic points show different behaviors. The space-time correlations in the regions where the circulations interact exhibit the iso-correlation-lines predicted by the elliptical approximation hypothesis. The space-time correlations of the streamwise and vertical fluctuations show distinct movements which imply the existence of anisotropy around the interaction region.
On two-scale dimension and its applications
Authors: Ain Qura , He Ji-Huan
Published: April 2019

Dimension or scale is everything. When a thing is observed by different scales, different results can be obtained. Two scales are enough for most of practical problems, and a new definition of a two-scale dimension instead of the fractal dimension is given to deal with discontinuous problems. Fractal theory considers a self-similarity pattern, which cannot be found in any a real problem, while the two-scale theory observes each problem with two scales, the large scale is for an approximate continuous problem, where the classic calculus can be fully applied, and on the smaller scale, the effect of the porous structure on the properties can be easily elucidated. This paper sheds a new light on applications of fractal theory to real problems.

Authors: Bonamis Guillaume , Mishchick Konstantin , Audouard Eric , Hönninger Clemens , Mottay Eric , Lopez John , Manek-Hönninger Inka
Published: April 2019

The authors report on a simple and easy-to-use GHz amplified femtosecond laser source. The laser source is based on a passively mode-locked oscillator with a near GHz repetition rate. GHz pulses are then selected, and the obtained bursts of pulses are further amplified in a high-power amplifier chain. The presented GHz femtosecond laser source is used with a galvanometric scanner to perform ablation experiments on copper, aluminum, and stainless steel. Specific ablation rates of 0.7, 2.3, and 1.4 (mm3/min)/W are reached. The role of the important experimental parameters, such as the number of subpulses in the burst, is highlighted. Thanks to a specific ablation scheme in the GHz mode, the ablation efficiency is then comparable to the case of single nanosecond pulses, but with the usual quality of femtosecond processing.

Authors: Munjiatun Munjiatun
Published: April 2019

Tulisan ini mengkaji tentang pendidikan karakter. Pendidikan karakter perlu dikuatkan oleh pihak terkait, yaitu : Keluarga, instansi pemerintah dan masyarakat. Tanpa adanya pendidikan karakter akan menurunnya kualitas moral generasi muda Indonesia, seperti yang kita lihat di media cetak dan elektronik yang menampilkan moral karakter siswa-siswi kita yang sangat bobrok. Di stasiun televisi ditayangkan tindakan menyontek saat ujian, minum-minuman keras, merokok, narkoba, pergaulan dan seks bebas, tawuran antar pelajar, peredaran video porno di kalangan pelajar serta  tindakan kriminal dan aksi brutal lainnya menuntut diselenggarakannya penguatan pendidikan karakter. Salah satu pendekatan pendidikan karakter yang dapat digunakan adalah pendekatan pengembangan rasional, pertimbangan, klarifikasi nilai, pengembangan moral kognitif, perilaku sosial, dan penanaman nilai. Pihak terkait dituntut untuk memainkan peran dan tanggungjawabnya untuk menanamkan dan mengembangkan nilai-nilai yang baik dan membantu anak membentuk dan membangun karakter mereka dengan nilai-nilai yang baik. Pendidikan karakter diarahkan untuk memberikan tekanan pada nilai-nilai tertentu –seperti rasa hormat, tanggungjawab, jujur, peduli, dan adil– dan membantu anak untuk memahami, memperhatikan, dan melakukan nilai-nilai tersebut dalam kehidupan mereka sendiri. penguatan pendidikan karakter menjadi salah satu solusi untuk mengurangi merosotnya moral bangsa yang terjadi pada saat ini.
El movimiento indígena colombiano y su relación con el giro decolonial en América Latina
Authors: Sandoval Forero Eduardo Andrés , Capera Figueroa José Javier
Published: April 2019

La compleja realidad asociada a las violencias en Colombia ha sido un gran campo de análisis y reflexión sociopolítica en los últimos tiempos, marcada por la fuerte presencia de un conflicto armado de larga duración, las prácticas de violencias múltiples de los grupos hegemónicos en el poder político, de las organizaciones políticomilitares antisistémicas, de los carteles de la droga y de los grupos paramilitares de viejo y nuevo tipo. No obstante, la praxis liberadora que emerge al interior/exterior del movimiento indígena colombiano, enfocado en la defensa de la tierra, el territorio, la vida y la cultura, responde a una amplia articulación con la cosmovisión y pensamiento crítico, horizontal y decolonial en las ciencias sociales de la región. Las acciones políticas desarrolladas por las comunidades y organizaciones indígenas representan un contenido de aspectos/componentes propios del pensamiento desde abajo, con la tierra y la izquierda (Abya Yala), enfocado a repensar sus propias dinámicas y también las ciencias sociales, por medio de experiencias que establezcan un peso teórico, conceptual y metodológico más allá del colonialismo-epistémico del momento. La metodología que se utilizó en el desarrollo del artículo responde a los siguientes procesos: 1) revisión teórica sobre los estudios decoloniales, el movimiento indígena y su vinculación con el pensamiento crítico latinoamericano; 2) el análisis de los procesos/movilizaciones del movimiento indígena colombiano y 3) la interrelación conceptual y metodológica entre el giro decolonial y la praxis del movimiento indígena como sujeto-colectivo en el escenario de la sociedad civil. El aspecto más sustancial encontrado fue el campo de oportunidad vigente en el estudio de los movimientos indígenas como sujetos sentipensantes, colectivos y comunales. A su vez, la oportunidad epistémica que constituye la decolonialidad como una forma de pensar alternativamente y desde abajo la realidad emergente del movimiento indígena, con respecto a la dinámica política interna de las instituciones y los sectores hegemónicos en Colombia.

Pilgrimage as a Social and Cultural Phenomenon of Russian Culture
Authors:   Surgut State University, Ilyina Alina Yurievna
Published: April 2019

The research deals with the pilgrimage phenomenon in Russian Orthodox culture which is considered in spatial and temporal contexts through the path taken by the pilgrim. The author attempts to review the space and time created by the pilgrim from a philosophical perspective. Special attention is paid to pilgrimage as a focus of social and cultural study through the genesis and ontology of the phenomenon. The research analyzes the particular way of thinking and reflection of the pilgrim and the core motive of pilgrimage, i.e. the intention to leave the material world and start a journey. Pilgrimage is impossible without its metaphysical feature that is regarded as a target of philosophical review and a social and cultural phenomenon. Pilgrimage is interpreted as an instruction of the Holy Fathers and the Holy Scripture of Orthodox culture. It was hypothesized that if the Christian culture was only in the mind and heart of the Creator, it would not be able to gain a real ontological and anthropological life. To materialize the Christianity and make it the basis of existence, it was necessary to translate the idea through pilgrimage available for people with a special intellectual energy. The author defines pilgrimage as the phenomenon of movement without fixing the time, distance, and settled way of life that seems to be fundamentally contrary to human nature. Thus, there is no alien space for pilgrimage because of the lack of identification of a person with a particular place. In this context, space is like a wide-open window that can be metaphysically captured only by the pilgrim.
Adyghe Feudal Elite in the 14th-15th Centuries According to Archeological Data (Markers of the Nobility in the Funeral Rite and Accompanying Things)
Authors: Fomenko Vladimir Aleksandrovich ,   Kabardino-Balkarian Scientific Center of  the Russian Academy of Sciences
Published: April 2019

The study discusses the requisites of archeological data for reconstructing the social structure of medieval societies, for example, the population of the Western and Central Ciscaucasia of the 14th-15th centuries. It is necessary to look at the history of elites and explore the graves of the late medieval Adyghe nobles. The author reveals several problems in studying the history of the region in the 8th-15th centuries and recommends historians to use an integrated archeological and ethnological approach. The researcher compares and contrasts the materials of the Adyghe monuments of the Khazar (the 8th-9th centuries), post-Khazar and pre-Mongolian (the 10th-13th centuries), and Golden Horde times (the 13th-15th centuries). The paper considers the data on historical and archeological sites related to the personality and activities of the legendary Prince Inal the Great. The study analyzes the creation of the Inal dynasty in the 14th-15th centuries and describes the social rank structure of the Belorechensk archeological culture. The markers of elites are determined in the funeral rite and accompanying things of the 14th-15th centuries.

Design changes are the primary contributor to disruption of time and cost performance of construction projects. Previous research in this domain lacks of detail studies on systematic review on the existing literature. This paper reviewed literature published in peer-reviewed journals and conference proceedings in the construction management field and had emailed several questions to the expert in construction industry. The objectives were to recognize the causes and impacts of design changes on project performance and to provide insights for future studies in Malaysian context. The findings indicate that design changes originate mainly from the owner side are identified as important causing factors to time overruns and cost overruns. This paper proposes framework for the management of design changes in construction projects.
GEOTECHNICAL INFLUENCE OF UNDERLYING SOILS TO PAVEMENT FAILURE IN SOUTHWESTERN PART OF NIGERIA
Authors: Omowumi Ademila
Published: April 2019

Roads in Nigeria are usually constructed without in-depth knowledge of the subsoil that serves as the foundation for the road elements. Road failures are often associated to poor construction materials or inadequate design without cognisance of the underlying soils. Engineering properties of ten bulk soil samples collected from the subgrade of Arigidi/Oke-Agbe highway were investigated to determine their suitability for highway pavement. Results show that all the subgrade soils below the failed locations have higher plasticity indices, which is an indication of their high swelling potential, and they are classified as A-7-6 clayey soils with high-water adsorption capability (16.1 – 22.4%) compared to subgrade soils from the stable locations. Low compacted density (1325 – 1928 Kg/m3), extremely poor CBR values; 8 – 31% (unsoaked) and 3 – 8% (soaked) which indicate percentage reduction in strength of the soils up to 77% on exposure to excessive moisture and the predominance of fines (> 59%) in the soils are responsible for the degree of instability. Furthermore, soft to low stiffness (49 – 131 kN/m2) and poor permeability of the subgrade materials underlying the pavement result to the failure characteristics witnessed. This study shows that the suitability and behaviour of subgrade soil is dependent on its engineering properties.

Published: April 2019

All mosques need to be equipped with facilities for people with disabilities (PWD) in fulfilling with the requirements of the Malaysian Standard Code of Practice (MS) on Access of Disabled Persons. However, most mosques in Malaysia do not fulfil these requirements in terms of providing facilities for the PWDs. This adversely affects the PWDs to engage in the social and economic mainstream. The research aim is to classify the conformity of disabled facilities provided at Fi-Sabilillah Mosque, Cyberjaya in Selangor. The two research objectives were established (1) to identify the spectrum of disabled facilities provided at the Fi-Sabilillah Mosque, Cyberjaya in Selangor and (2) to determine the compliance of the disabled facilities as outlined in the MS. Purely qualitative methods were adopted in terms of visual study, audit survey and a semi-structured interview with the architect. A condition audit checklist was established using document analysis method on three main documents. The findings indicate 58% of the facilities are available and follow the MS, 13 % items were available but not comply with the standard measurement and 29% of the disabled facilities are not available within the mosque. Therefore, it can be stated that there is poor design, weak enforcement and lack of awareness among the stakeholder, local authority and the designer of the mosque regarding the disabled facilities. Therefore, enforcement is a priority to ensure the needs and right of the disabled user are considered in designing a mosque.
ENVIRONMENTAL DEVELOPMENTS IN MALAYSIA: A REVIEW ON CHALLENGES AND OPPORTUNITIES AHEAD TO ECO-INNOVATE
Authors: Keshminder JS
Published: April 2019

Climate change is taking a toll on governments around the world as it is a challenge to determine the most effective environmental policies to promote eco-innovation. This paper investigates the environmental developments that have taken place in Malaysia to address the challenges and opportunities to promote eco-innovation. Past and present literature was qualitatively analyzed to prepare the environmental review for this study. The results suggest that Malaysia is implementing more superior environmental policies to promote eco-innovation. Command and control-based approach is slowly being replaced with guided self-regulation approach and cradle-to-cradle principle. The evidence suggests several shortcomings where the large industries are not given adequate focus under the environmental agenda and a holistic eco-innovation framework is yet to emerge.

Cultural adaption and validation of the German version of the diagnostic thinking inventory (DTI-G) / Ein Instrument zur Erhebung diagnostischer Kompetenz: Validierung und kulturelle Adaptation des Diagnostic Thinking Inventory (DTI-G)
Authors: Schäfer Axel Georg Meender , Sebelin Britta , Spitzer Lena
Published: April 2019

Diagnostic ability is essential for expert professional practice. Several instruments have been developed to assess diagnostic skills independent of specific knowledge. One such instrument is the diagnostic thinking inventory (DTI), which is used in different settings to evaluate diagnostic performance and has shown acceptable reliability and validity.

The aim of the present study was to translate and validate a German version (DTI-G).

Cultural adaptation and translation were performed according to international guidelines. Internal consistency and item discrimination indexes were calculated. The factorial structure of the DTI-G, test-retest reliability and known-groups validity were tested.

A total of 388 physiotherapists completed the questionnaire. The internal consistency was good for the overall score of the DTI-G (Cronbach’s a = 0.84). Exploratory factor analysis yielded a five-factor solution with 21 items that explained 55% of the total variance across items. A confirmatory principal component analysis resulted in the same five-factor structure, showing an acceptable to good overall fit of the model (CFI = 0.93; RMSEA = 0.05; SRMR = 0.06). Test-retest reliability was found to be good (intraclass correlation coefficient ICC2,1 = 0.87, p < 0.001, n = 118). The difference between participants with more than 9 years of clinical experience and those with less than 9 years of clinical experience (median split) was significant (t385 = 6.00, p < 0.001), supporting known-groups validity.

The results support construct validity and indicate good test-retest reliability of the DTI-G. The DTI-G can be used to measure and develop diagnostic ability of physiotherapists in clinical practice and education. Further research is necessary to validate the questionnaire for other health professions.

Published: April 2019

The aim of the present study was to evaluate plasma levels of chemerin, myeloperoxidase (MPO), fibroblast growth factor-21 (FGF-21), thioredoxin reductase-1 (TrxR1), and matrix metallopeptidase-9 (MMP-9) in acquired aortic valve (AoV) stenosis patients to determine correlations between the studied cellular factors, and also clarify the predictive values of these factors as biomarkers in AoV stenosis. AoV stenosis patients were classified into three groups: 17 patients with mild AoV stenosis; 19 with moderate and 15 with severe AoV stenosis. Twenty-four subjects without AoV stenosis were selected as a control group. Our findings suggest that AoV stenosis might be associated with increased chemerin, TrxR1, MPO, and FGF-21 levels in plasma. Moreover, these factors and also MMP-9 already reached statistically significantly elevated levels in the early stages of AoV stenosis, but MPO levels were more pronounced in patients with moderate and severe AoV stenosis. Chemerin was correlated with all of the studied cytokines; TrxR1 and MMP-9 were correlated with several other cellular factors. Our findings (by ROC analysis) suggest that MPO and chemerin might serve as specific and sensitive biomarkers for AoV stenosis without grading the severity, but, in relation to mild AoV stenosis, TrxR1, FGF-21, and MMP-9 also reached good or moderate levels as biomarkers. The cellular factors might serve as novel diagnostic and prognostic biomarkers in AoV stenosis patients, while chemerin and MPO may be more powerful.

Published: April 2019

The aim of this study was to investigate the possibility of using monocytes/macrophages as mediators in human herpesvirus-6 (HHV-6) infection of thyroid gland tissues in autoimmune thyroiditis (AIT). Seventy-three AIT patients were enrolled in this study. The control group consisted of 80 blood donors. Monocyte/macrophage isolation for AIT patient samples was performed by adherence. HHV-6 was detected in peripheral blood mononuclear cell (PBMC) DNA samples using nested polymerase chain reaction (nPCR). Gene expression of HHV-6 active infection marker (U79/80) and chemokine receptors (U12, U51) in patient monocyte/macrophage samples and blood donor PBMC samples was detected using reverse-transcription PCR. HHV-6 viral load was detected by using quantitative-PCR technique. The HHV-6 genomic sequence was found significantly more frequently among AIT patient than control group samples. Markers of active infection were found in 8 AIT patient monocyte/macrophage samples (11%) and in none of control group PBMC samples. HHV-6 U51 mRNA expression was detected only in AIT patient samples (2/24 previously positive for HHV-6). Since HHV-6 genomic sequences were found significantly more frequently in AIT patient samples and active infection markers were found in patient monocytes/macrophages, our results suggest that monocytes/macrophages may be used by HHV-6 as mediators for thyroid gland infection.

Published: April 2019

Depression is among the most common mental disorders in primary care. Despite high prevalence rates it remains to be under-diagnosed in primary care settings over the world. This study was aimed to identify Latvian family physicians’ (FPs) experience and attitude in diagnosing and managing depression. It was carried out within the framework of the National Research Programme BIOMEDICINE 2014–2017. After educational seminars on diagnosing and managing depression, FPs were asked to complete a structured questionnaire. In total 216 respondents were recruited. Most of the doctors, or 72.2% (n = 156), agreed with the statement that patients with depression use primary care facilities more often than other patients. More than a half of physicians, or 66.3% (n = 143) quite often asked their patients about their psycho-emotional status and 65.7% (n = 142) of clinicians thought that they can successfully assess a patient’s psychoemotional status and possible mental disorders. The majority, or 91.6 % (n = 198), supposed that routine screening for depression is necessary in Latvia. Despite the fact that a significant number, or 62.6% (n = 135) of FPs thought that their practice was well suitable for the treatment of depressive patients, half of the respondents, or 50.9% (n = 110), assessed their ability to build a trustful contact and to motivate patients for treatment as moderate. Although FPs acknowledged the importance and necessity to treat depression, current knowledge and management approaches were far from optimal. This justifies the need to provide specific training programmes for FPs.

Bone density of the femur body of rabbit was determined in vivo. Experimental osteoporosis was induced by ovariectomy and subsequent injections of methylprednisolone. In the greater trochanter region of right femur, defects were created and filled with granules of hydroxyapatite and tricalcium phosphate (HAP/TCP 70/30) or HAP/TCP 70/30 together with 5% strontium. After three months, the animals were euthanized. The bone mass density of the right and left body of femur was measured by cone beam computed tomography (CT) scan. The results of the study showed that the right femur of the rabbit, where biomaterials had been implanted, and the left femur, where no biomaterial implantation occurred, became denser after filling the defect with HAP/TCP 70/30 ceramic granules or 5% Sr modified HAP/TCP ceramic granules. There was no difference between operated and non-operated legs and HAP/TCP and HAP/TCP with 5% strontium groups.

The People’s Republic of China is increasing its influence around the world every day. It’s hard not to notice the aggressive economic expansion being carried out by China in the Asian region. Chinese presence is felt in Africa, South America and even in Europe. By engaging in a trade war with the United States, China thereby challenged the most influential economy in the world, which is confirmed by its ambitions as a world leader. To meet these ambitions, a powerful transport and logistics support is necessary, which gave rise to the “Belts and Ways” initiative. The initiative “One Belt - One Road” combines two projects: “The Economic Belt of the Silk Road” and “The Sea Silk Road of the XXI Century”. This means that, in addition to the traditional land routes of the Silk Road, Beijing is exploring the sea routes along the African continent and in the Pacific Ocean. Since the initiative does not have a clear strategy, the northern routes that have recently become relevant are also considered by the Chinese authorities.

The search for an alternative to the Suez Canal has repeatedly prompted researchers to use the Northern Sea Route as a trading artery linking Europe and Asia, but climatic conditions and technical capabilities did not allow this idea to be realized. The current situation in the Arctic region allows us to talk about new development prospects.

China is actively interested in the Arctic: since 2013, it has an observer status in the Arctic Council, has been increasing its presence in the region by organizing scientific expeditions, building icebreakers, introducing its own brand “Northern Silk Road”, and also investing in projects like “Yamal LNG». China outlined its presence in the Arctic region in a white paper published in January 2018. One of the main goals that Beijing sets for itself is multilateral cooperation in the development of the Northern Sea Route.

The author of the article analyzes the origins of such interest, as well as possible threats to Russia. The study also examines the position of European partners in the participation of the development of the SMP, bilateral relations with the Chinese side and the ratio of the strategy of the European Union, China and Russia in the High North. The author gives a geopolitical rationale for Chinese initiatives that are aimed at creating the conditions for intensive navigation in the northern areas.
Cooperation between the Eurasian Economic Union and the Silk Road Economic Belt: Benefits, Risks, Achievements
Authors: Garbuzarova E. G.
Published: April 2019

The article is devoted to the advantages, risks and achievements of cooperation between the Russian integration project “Eurasian Economic Union” (EAEU) and the Chinese initiative “Silk Road Economic Belt” (SREB). The Eurasian space has a strategic importance for Russia and China, so the political leaders of these global powers decided to join together the EAEU and the SREB for the development, strengthening and expansion of cooperation in the field of economy. On the one hand, the interaction of the two integration projects opens wide opportunities for all participants: economic growth, technological modernization, creation of transport and logistics infrastructure. Russia and China share a common vision of the future foundations of the New World Order. In contrast to the Western model of the organization of international relations on the principle of unipolarity, Russia and China defend the model of a polycentric world order. On the other hand, there are problems that can cause competition between Russia and China. The problems of industrialization of the EAEU member-states, the possible competition between Russian and Chinese goods in the Eurasian market as well as in the field of industrial technology may appear. At the same time, it is important to understand that the interests of Russia and China largely coincide rather than diverge. The interests of both states are not only economic in nature but also related to Eurasian security issues. The first beneficial projects having been signed within the cooperation between EAEU and SREB aim at the development of transport infrastructure and financial assistance to the member-states. Considering the reverent attitude of the post-soviet states to national sovereignty the Chinese project looks the most attractive due to the absence of a supranational body. However, this fact does not exclude the possibility of getting the Central Asian states into excessive financial dependence on China. Meanwhile, the EAEU will help to balance China’s economic and political relations with the Central Asian states.

In the context of globalization the cooperation between the EAEU and the SREB could be the first step towards the creation of major international economic structure. Cooperation between the Russian and Chinese projects has enormous potential for effective mutually beneficial development and opens wide opportunities for the participating states. The cooperation of the two projects will strengthen the geopolitical position of Russia and China in Eurasia as opposed to the geopolitical activity of the United States.

STRATEGI IMITASI DAN MANAJEMEN PENGETAHUAN DALAM PENGEMBANGAN INOVASI PLA (POLY LACTIC ACID) PADA AGROINDUSTRIKEMASAN BIODEGRADABEL DI INDONESIA
Authors: Filianty Fitry
Published: April 2019

Indonesia has the potential for development of PLA (Poly Lactic Acid) as biodegradablepackaging agroindustry due to the availability of raw material, such as tubers as a source ofstarch and lignocellulose as a source of cellulose, but Indonesia has limitations in terms of itstechnology. This was due to the intensity and quality of the research that has not beenadequate. For that condition, imitation strategies can be developed for PLA (Poly Lactic Acid)agroindustry in Indonesia and the level of product imitation strategies is knockoff or cloning.At that level, PLA agroindustry to be developed completely replicate existing products but haveother brands. With this strategy, the PLA agroindustry is expected to produce a cheaper priceproduct because of the availability of raw materials in Indonesia that easy to fine. Rawmaterial for PLA that can be selected from cassava tubers beacause its easy in cultivation andcheaper among other types of bulbs. To improve competitiveness, the company who built theimitation strategy needs to be managed with the application of knowledge management inorder to be able to last long existence.
PENENTUAN UKURAN LOT GABUNGAN DENGAN BARGAINING GAME DAN CONSIGNMENT UNTUK PEMANUFAKTUR DAN PEMBELI TUNGGAL

This paper considers the integrated inventory model, where the ordering lot is no longerdetermined by the buyer, but it is determined by both parties in order to minimize the totalinventory cost. There are three approaches in determining the joint lot size: Joint Economic LotSize (JELS), Joint Economic Lot Size with Bargaining Game, and Joint Economic Lot Size withConsignment. On JELS with Bargaining Games, the manufacturer will offer rebates to thebuyer, since buyer will be at the disadvantage side if the manufacturer only offers JELS.Furthermore, on model JELS with Consignment, the manufacturer will own the product until itis used by the buyer. Using JELS, manufacturer makes a savings of 8.73% while the buyersuffered a loss of 3.37%. The result of using the JELS with Bargaining Game will give themanufacturer a savings of 6.63%, while the inventory cost for the buyer is the same with theinitial condition (individually). This paper concludes that using the JELS with consignment willprovide savings to the manufacturer as well as for the whole system.
