Influence of the mix composition on the thixotropy of 3D printable mortars
Authors: Baz Bilal , Remond Sébastien , Aouad Georges
Published: September 2020

Digital fabrication of concrete elements requires a better understanding of the rheological behaviour of the cementitious material used. Fresh concrete is known to be a thixotropic material having time-dependent characteristics. Moreover, fresh mortars used in three-dimensional (3D) printing should maintain a sufficient shear stress to avoid any deformation or failure during printing. This paper concentrates on the experimental investigation of the buildability properties of different printable materials, on the basis of shear stress, measured using the Fall cone test. The effect of different constituents such as high-range water reducer, viscosity-modifying agent, limestone filler and water content on the evolution of the yield stress in mortars, derived from the shear stress, are studied experimentally and discussed in detail. Accordingly, the change of variables induces a quasi-linear relationship with the growth of the structuration rate and structural build-up (Athix) of mortars, which corresponds to the variation of the yield stress with time. These findings enable the use of the Athix concept and the proposed curves for designing new printable mixes that better suit the buildability properties of large-scale 3D printed structures.

Educação popular, intersubjetividade e espiritualidade: uma relação de memória sobre as contribuições do conceito de comunicação na obra pedagógica de Paulo Freire
Authors: Rodríguez B. Luis Fernando
Published: September 2020

A importância pedagógica e histórica de Paulo Freire é fundamental para pensar a construção da memória coletiva, processos de reconhecimento social e representação política em América Latina. Seu pensamento e obra, não só têm a ver com o campo educativo especificamente, também diversas áreas das chamadas ciências sociais, entre elas a comunicação, recebem uma grande influência desde sua visão esclarecedora, crítica e cultural. Daí torna-se importante compreender a importância transversal de categorias sociais, que confluem em torno de elementos tais como o diálogo, a mediação, o popular, a libertade, o amor e a esperança. Entre muitas contribuições de sua inspiração está pensar e assumir a comunicação como uma forma crítica de desalienação dos sujeitos e emancipação do povo daquelas estruturas, tanto epistémicas como políticas que o manipulam e impedem sua própria produção de conhecimento e autonomia. A cinquenta anos da publicação da Pedagogia do oprimido, este texto apresenta uma pequena lembrança do significado crítico da comunicação desde sua obra e memória.

Authors: ÇAMLIBEL Osman
Published: September 2020

Son yıllarda yongalevha üreticileri piyasa şartlarında rekabet edebilmek için kapasite artırarak üretim maliyetlerini azaltabilmeyi hedeflemiştir. Bu çalışmada, yonga levha üretim hattında %40 sarıçam (Pinus sylvestres L), %30 sapsız meşe (Quercus petraea L), %20 kavak (Populus alba L), %10 talaş ve 1:1.35 mol üre-formaldehit tutkalı kullanılmıştır. Proseste üretim parametreleri sabit kaldı. Tek değişken sıcak pres üretim parametreleridir. Sıcak pres parametrelerinden pres hızını ve pres sıcaklığını %15, %20, %25 artırmıştır. Üretilen levhaların fiziksel test ve formaldehit emisyon performansları ölçüldü. Referans levhalar baz alınarak tüm testler yapılmıştır. Her bir test grubundan beş levha ölçülmüştür. Tüm fiziksel testler; levha yoğunluğu (T; 622 gr/cm³, T2; 624.6 gr/cm³, T3; 630 gr/cm³, T4; 630 gr/cm³), kalınlığına suda şişmesi 24 saat (T1; %15.24, T2; %13.8, T3; %16.46, T4; %15.46), 24 saat su alma (T1; %78.14, T2; 78.52, T3; 79.12, T4; 78.62) değerlerinde ölçülmüştür. Levhalardaki formaldehit emisyonu ölçmek için, TS EN 120 perforatör yöntemi uygulanmıştır. Formaldehit gaz emisyonu (T1; 14.53 mg/100gr, T2; 14.84 mg/100gr, T3; 15.16 mg/100gr, T4; 15,36 mg/100gr) analiz edilmiştir. Çalışmanın sonucunda, fiziksel test sonuçları diğer test grupları arasında küçük bir fark olduğu görülmektedir. Fakat levhaların formaldehit emisyonu test sonucu diğer test grupları arasında önemli farklar ölçülmüştür. Bu farklılıklar sıcak pres parametreleri (pres hızı, pres sıcaklığı) ve 1:1.35 mol üre formaldehit tutkalından kaynaklandığı düşünülmektedir.

Published: September 2020

Background: The determination of amino acid supplements for broiler chicken requirements based on performance does not always reflect maximum profitability. Objective: To estimate the optimal levels of digestible threonine (Thr) and sulfur amino acids (SAA) in diets for broilers based on an economic analysis. Methods: Two dose-response assays were conducted, and each assay was divided into three phases: initial (1-14 days), grower (15-28 days), and finisher (29-42 days). Five hundred and sixty male Cobb 500® broilers were randomly distributed to seven treatments with increasing levels of the amino acid (SAA or Thr), with four replicates and 20 birds each. Bodyweight gain (BWG) and feed intake (FI) were used to fit a segmented model. Gross income (GI), total feed costs (TFC) and gross margin (GM) were calculated based on local values. Results: Increasing levels of amino acid elicited a response in BWG and FI for all evaluated phases. The estimates for maximum profit based on GI and TFC were 223, 504, and 975 mg SAA/bird/d, and 236, 696, and 1,042 mg Thr/bird/d in starter, grower and finisher phases, respectively. Conclusion: Varying the AA prices affected only slightly the economic optimal intake of Thr and sulfur amino acids. Despite market fluctuations, the economic approach presented in this study demonstrates to be a helpful tool to choose the ideal inclusion level of amino acids in the feed.

Published: September 2020

Background: Creatine and its precursor, guanidinoacetic acid (GAA), decrease protein degradation, avoiding amino acid offset to gluconeogenesis. Objective: To evaluate the inclusion of GAA in the pre-initial diet (1 to 7 days) on performance, digestibility, and blood parameters of broilers from one to 21 days of age. Methods: 252 male broiler chickens aged one day were distributed in a completely randomized design with seven replicates and 12 animals per experimental unit. Treatments consisted of a basal diet, and the basal added with 0.10 and 0.20% GAA. Results: From days 1 to 7, a tendency on improved feed conversion (FC) was observed for broilers receiving 0.20% GAA (p<0.10). Between 7 and 14 days, FC improved, as well as a tendency was observed on improved weight gain in animals fed 0.20% GAA. Animals that received 0.20% GAA showed higher blood concentrations of creatine kinase. Blood creatine and blood glucose did not differ between treatments at day six. The assimilation coefficient of crude protein increased during days 3 to 7 for animals receiving 0.20% GAA. On the period between 17 and 21 days, no difference was observed between treatments. Intestinal weight and length did not show significant differences. Conclusion: Dietary inclusion of 0.20% GAA during the pre-initial stage could improve weight gain and feed conversion of broilers between 1 and 14 days of age.
PHYSICOCHEMICAL CHARACTERIZATION OF ÑUÑA (Andean popping) BEAN PROTEIN EXTRACT
Authors: Vargas-Salazar Tania Alejandra , Wilkinson Kevin A , Urquiaga-Zavaleta Josué Manuel , Rodríguez-Zevallos Antonio Ricardo
Published: September 2020

Background: Although legume protein extracts are useful in food preparation and processing as foam stabilizers and as viscosity, palatability and nutrition enhancers, many legume proteins from South America have not been characterized extensively. One such legume is the ñuña bean (Phaseolus vulgaris L.), which is cooked using dry heat until the cotyledons rapidly expand with a pop. The bean is widely cultivated in the Andes, but almost unknown elsewhere. Objective & Methods: In this study, we characterized ten functional properties of a ñuña protein extract using standard food analysis methods. Results: The extract was similar to other legume protein extracts for many properties (amino acid profile, proximate analysis, yield, water absorption, color, isoelectric point, and thermogravimetric analysis). The electrophoretic analysis revealed that the sample was nearly pure phaseolin. Additionally, the ability to form foam and increase solution viscosity were comparatively low when contrasted to other extracts. Conclusion: These properties make ñuña protein extract useful as a nearly pure phaseolin nutrition enhancer in beverages where foaming and high viscosity are undesirable, such as in fortified beverages, drinkable yogurts, or protein supplements. The extract may also have relevance as a weight-loss supplement. Therefore, we expect that incorporating ñuña protein in processed foods would be a straightforward process.

Published: September 2020

Objective: to assess how cerebral stroke (CS) in patient’s history affectы length life of patients with stable coronary heart disease (СHD), included in the СHD PROGNOSIS registry.Materials and methods. We analyzed the data of patients from CHD PROGNOSIS registry who underwent coronary angiography and confirmed CHD diagnosis (n = 541, including 432 men and 109 women) during the reference hospitalization in the National Medical Research Center for Therapy and Preventive Medicine of the Ministry of Health of Russia from 01 / 01 / 2004 to 31 / 12 / 2007. The average age of men and women was 57.5 ± 0.4 and 60.9 ± 0.9 years, respectively. During reference hospitalization, we took into account CS / transient ischemic attack in anamnesis (retrospective part) and frequency of reaching endpoints (general and cardiovascular mortality, myocardial infarction and CS after 4 and 7 years of follow-up (prospective part). In case of 4-year observation, therapy response was 89 %, in case of 7-year observation – 93 %.Results. Twenty (3.7 %) patients had CS or transient ischemic attack in anamnesis at reference hospitalization, 284 (52.5 %) patients suffered myocardial infarction (p < 0.001). There were revealed differences in patients with coronary artery disease, which cannot be detected in the anamnesis by age, sex, presence of comorbid burden, arterial hypertension and diabetes mellitus, non-cardiological diseases, smoking frequency. The relative risk of death from all causes at 4- and 7-year follow-up was 3.3 and 2.4 times higher, respectively (p < 0.05). Patients with CS in anamnesis demonstrated 25 and 45 % overall mortality in 4 and 7 years, their cardiovascular mortality was 25 and 35 %, respectively. Patients without CS in medical history demonstrated 9 and 18 % overall mortality after 4 and 7 years of follow-up, cardiovascular mortality was 8 and 12 %, respectively (intergroup differences are statistically significant at p < 0.05–0.01).Conclusion. It was noted that patients with CHD and CS in anamnesis were older, percent of women among them was higher, they more often suffered from grade II–III hypertension and diabetes mellitus, had more comorbidities, but smoked less often. CS in anamnesis significantly worsened the medium-term and long-term life prognosis for patients with CHD, increasing overall and cardiovascular mortality.

Authors: Dimitriadi T. A. , Burtsev D. V. , Dzhenkova E. A. , Kutilin D. S.
Published: September 2020

Background.Currently, little is known about the specific microRNAs involved in the development of cervical intraepithelial neoplasia(CIN1, 2, 3) and the transition to cancer in situ (CIS). Our meta-analysis allowed us to isolate 8 microRNAs (hsa-miR-1246, hsa-miR-145-5p, hsa-miR-196b-5p, hsa-miR-34a-5p, hsa-miR-20a-5p, hsa-miR-21-5p, hsa-miR-375-5p, hsa-miR-96-5p) with potential significance in the progression of precancerous diseases to cervical cancer.Objective:to analyze the expression features of hsa-miR-1246, hsa-miR-145-5p, hsa-miR-196b-5p, hsa-miR-34a-5p, hsa-miR-20a-5p,hsa-miR-21-5p, hsa-miR-375-5p, hsa-miR-96-5p and their target genes, as well as genes associated with them in common signaling pathways in the tissues of the cervix in patients with CIN1–3 and CIS.Materials and methods.To assess the expression level of microRNA and matrixRNA, the quantitative polymerase chain reaction in real time method was used. Data analysis was carried out in the Python programming language using the SciPy library. Search for target genes was performed using the TarPmiR algorithm and the overrepresentation of microRNAs in signaling pathways (Over-Representation Analysis) was analyzed. To identify genes associated with target genes in common signaling pathways, GIANT (Genome-scale Integrated Analysis of gene Networks in Tissues) and network integration with several associations algorithms were used.Results.For microRNAs miR-145, miR-196b, miR-34a, miR-20a, miR-21, miR-375 and miR-96 a decrease in expression was found in the subgroup of patients with CIS, while for 4 microRNAs (miR-145, miR-34a, miR-20a and miR-375), an increase in the expression level was found for CIN1, 2. The detected features of microRNA expression in subgroups of patients with CIN1–3 and CIS also affected the expression of their target genes (CDKN2A, MKI67, TOP2A and CD82), as well as the genes associated with them in common signaling pathways (PGK1, THBS4 (TSP4) and ECM1).Conclusion.Thus, the study revealed that each degree of CIN is characterized by its own specific molecular profile – the differential expression of microRNAs, their target genes and the genes associated with them in the general signaling pathways.

The interplay of autophagy and epithelial-to-mesenchymal transition in cancer progression
Authors: Ryabaya O. O. , Prokofieva A. A.
Published: September 2020

Autophagy and epithelial-to-mesenchymal transition (EMT) are the main biological processes involved in tumor progression, and are closely linked. On the one hand, activation of autophagy provides energy and essential nutrients for EMT during the metastases spreading, which is required for tumor cells survival in adverse environmental conditions. On the other hand, autophagy, acting as a tumor suppressor, tends to inhibit metastasis by selectively suppressing the transcription factors of EMT in the early stages. Therefore, inhibition of EMT by inhibitors or inducers of autophagy may be a new strategy for antitumor therapy. Thus, the aim of this review is to highlight current knowledge about the crosstalk between autophagy and EMT processes in tumor progression and to summarize data supporting the necessity of parallel regulation of two processes through signaling pathways.

Territorial impacts of sea-level rise in marsh environments. The case of the Bay of Cádiz, Spain
Authors: Vázquez Pinillos F.J. , Marchena Gómez M.J.
Published: September 2020

How can sea-level rise affect territory? Has territorial planning adjusted to this new situation? This paper analyses the possible ramifications of changes in tidal recurrence over the course of this century in a potentially vulnerable marsh environment, such as the Bay of Cádiz, in southern Spain, where sea-level rise is already a fact. For that purpose, the regionalisation criterion is used as a basis for adjusting the magnitude of global problems to subregional scale. Geographic information systems are applied to portray the forecasted territorial changes according to the RCP4.5 and RCP8.5 scenarios presented by the Intergovernmental Panel on Climate Change (IPCC) for the years 2050 and 2100. Projections of sea-level rise show that the tide is travelling farther inland, not just invading unoccupied areas of marshes and beaches but also reaching urban and productive areas. Estimates indicate that the floodable area could expand by more than 20% in 2050, with a further 2,000 ha of flooded areas added in 2100 for either of the two scenarios used. The occurrence of these changes, regardless of the model used, would therefore entail an alteration of the environmental, social, cultural and economic values and elements of the Bay of Cádiz, with the Natural Park being the most affected area. In response to these consequences, the need to apply the resulting projections to other variables is insisted on, with a view to introducing territorial management tailored to this new and already present reality. Application of the regionalisation criterion to study repercussions of the climate crisis in the Bay of Cádiz could serve as a precedent for the development of adaptation strategies in other marsh environments at subregional or local level.

This study aims to determine  the supporting factors, and inhibiting factors in the implementation of village fund policies in infrastructure development. This research used descriptive qualitative approach. This research was conducted in Purba Manalu village, Humbang Hasundutan regency, Indonesia. The primary data were gained by conducting interviews with 11 informants, and the secondary data were gained through literature elaboration to support primary data.  The results indicate that the implementation of village funding policies in infrastructure development in the location is still not optimal. This is influenced by some factors namely namely (1) communication, (2) resources, (3) disposition (attitude), (4) bureaucratic structure. It is then divided into inhibiting and supporting factors.  The inhibiting factors for the acceleration of infrastructure development in PMV are the low level of education, the lack of village spatial planning experts in helping to build better and more organized village infrastructure, and the land acquisition factor. The supporting factors are the ability of the implementers of development (stakeholders) in empowering local communities in the implementation of rural infrastructure development, sources of funds for infrastructure development, availability of complete village facilities and infrastructure such as land in support of VF policies.

Published: September 2020

Deposit of compensation at the Court which is carried out in land acquisition for the public interest is one of the solutions to accelerate the development process. The disagreement of the parties regarding compensation has made the agency managing the project use a consignment mechanism to solve this compensation problem. Therefore, this research is focused on 3 (three) main problems. First, what is the process of assessing and determining compensation for land acquisition for the construction of the Padang-Pekanbaru toll road on Jalan Padang-Sicincin? Second, what is the process of filing an objection to the determination of the form and / or amount of compensation at the Pariaman District Court? Third, how is the implementation of deposit for compensation in land acquisition for the construction of the Padang-Pekanbaru toll road on the Padang-Sicincin road? This type of research is empirical juridical legal research and to answer the above problems, this study uses primary data and secondary data. Primary data is obtained through field research, while secondary data is obtained from tracing laws and regulations and decisions of Constitutional Court judges. The data analysis was conducted in a descriptive qualitative manner. The results showed that the process of appraising and determining compensation for land acquisition was carried out starting from the process of appointing the appraisal team, the assessment of compensation by the appraisal team, deliberation, and the process of determining the compensation. The appointment of an appraisal team is determined by the Chief Executive of Land Acquisition using the direct procurement method. The appraiser makes an appraisal using the Fair Replacement Value and refers to the SPI 306 Technical Guidelines. The results of the appraisal are used as the basis for deliberations to determine compensation. The fact is that the deliberations are carried out as it should be, but the price set by the Appraiser (Appraisal) is as if only a final price that must be agreed upon by the entitled Party, even though the price recommended by the Appraisal is a price that is the price for negotiating with the community land owner. The process for filing an objection to the determination of the form and / or amount of compensation at the Pariaman District Court is in accordance with the Supreme Court Regulation No.3 of 2016 and is a form of legal protection for land rights owners. The implementation of land’s deposit compensation at the Pariaman District Court is carried out in accordance with the Supreme Court Regulation Number 3 of 2016 and in the Compensation of the Damages awaits a court process that has permanent legal force so that the money can be given to the party entitled to receive it

Authors: Krismantoro Damianus , Oktavany Vernando Rony
Published: September 2020

The presence of waste can have negative impacts as well as positive impacts. Waste has a negative impact when the management and utilization of waste is not optimal so that it can cause environmental damage. However, waste becomes useful when it is managed properly. The handling and management of waste must receive special attention from the Government. This study uses a normative juridical approach. The results showed that the management of household waste and household-like waste by the Government of the Special Region of Yogyakarta was carried out based on Perda DIY No. 3 of 2013 concerning Management of Household Waste and Waste Similar to Household Waste, by increasing supervision both in efforts to reduce waste and in handling waste. However, the limitations of the waste collection area become an obstacle in proper waste management.

Published: September 2020

The study suggests alternative conception of expected and unexpected losses in corporations. Unlike the classical conception, it suggests backing up expected losses with risk capital, taking into account loss causes during different phases of business cycle. Whereas unexpected losses that are the source of uncertainty should be adjusted based on adapted VaR method tests, stress tests and limitations that include principles of dynamic back up allocations. That should ensure timely forecast of significant financial risks guaranteeing efficient development of risk profile of corporations, and in the end increasing potential for efficient control on financial risks. From the standpoint of further conception advancing, a method for determining unexpected VaR losses was developed and implemented; it is supported with special software dedicated to bankruptcy risk symptoms identification in corporations.

Published: September 2020

Over the years, Nigerian researchers in environmental engineering and chemistry have been evaluating a variety of technologies for the remediation of petroleum industry polluted surface and groundwater. In this mini-review, the recent advances in this regard over the past two years were evaluated. This was done as an appraisal of research efforts to understand the current research trend and gain a proper perspective of the required/needed future approach in the research area. It was observed that most studies are still focusing on evaluating the problems instead of finding actual solutions. Development of workable and novel solutions are urgently needed. It can be in the form of better remediation techniques or via the development of alternative technologies for utilizing the waste/pollutant materials. The paper has given a clear opinion on the progress of environmental protection and sustainability in the Nigerian context. The environmental regulations scenario in the country is marred by malpractices and corruption more stringent policy enforcement will help in the achievement of environmental protection.

Background: The worse prognosis in cancer patients with COVID-19 infection in the context of the pandemic, compared to that in the general population, poses new challenges to ensure the perioperative safety.

Aim: To reduce the risk of infection for cancer patients in the perioperative period and to prevent severe COVID-19.

Materials and methods: During two months of the COVID-19 (from March to April 2020), we performed 158 surgical interventions: 49 for breast cancer, 31 for lung cancer (videothoracoscopic segmental and lobar resections), 12 for stomach cancer (8 distal and 1 proximal laparoscopic subtotal gastric resections, 3 gastrectomies), 16 laparoscopic resections for colorectal cancer, 29 resections with a reconstructive plastic for malignant skin tumors, 21 palliative and diagnostic operations (diagnostic thoracoscopy and laparoscopy, laparoscopic colostomy).

Results: Preventive administration during preparation for surgery (interferon-al-pha2b and low molecular weight heparins) and for suspected infection (antibiotics, low molecular weight heparins and dexamethasone 12 mg/day intravenously) allowed for lower rates of the new coronavirus infection (1.3%) and its severe cases (0%) during surgical treatment of malignant tumors.

Conclusion: Surgical treatment of cancer patients in the context of a new coronavirus infection pandemic should be carried out with strict adherence to anti-epidemic measures.

Desde mediados del siglo XX, el campo ha sido el escenario del conflicto armado interno y, por lo tanto, del despojo. En este se han generado procesos de desarrollo completamente diferentes a los de las ciudades, las cuales han tenido no solo el favorecimiento de las políticas públicas, sino también de las inversiones privadas que han encontrado allí mercados necesarios para sus negocios. Los resultados son evidentes: unas brechas económicas, productivas y sociales crecientes, y una deuda con el campo que, en vez de saldarse, se mantiene e, incluso, aumenta, lo cual dificulta que la ruralidad se constituya en una opción de vida digna para sus pobladores. En este artículo se hace un balance de estas brechas en los últimos años, que aborda elementos económicos y sociales, y muestra que la deuda del país con la ruralidad sigue siendo una tarea urgente

The purpose of this study was to determine the effects of painting parameters using a spray to its glossiness. Three parameters varied were: (i) comparison of paint composition and thinner (1:1.2; 1:1.4 and 1:1.6), (ii) spraying distance (110 mm, 130 mm and 150 mm), and air pressure (3.5 bar; 4.5 bar and 5.5 bar, while the glossiness measured in gloss unit (GU) using a gloss meter. The experimental design method used was the response surface method with Box-Behnken design. A series of tests were carried out prior to ANOVA and optimization with Minitab: (i) lack of fit test, (ii) simultaneous parameter test, (iii) the coefficient of determination test, (iv) identical test, (v) independent test and (vi) normal distribution test. Out of three parameters, the most influential one is composition with a coefficient of mathematical equation of 6.592. In this study, the highest value in the 10th trial was 57.3 GU which was occurred when the parameters used were: distance of 130 mm, composition 1: 1.6 and pressure 3.5 bar. On the contrary, the smallest value GU in the 7th experiment was 35 GU with a distance of 110 mm, composition 1:1.4 and pressure 5.5 bar. From processing data using Minitab, the maximum gloss value was 58.76 GU with distance 116.86 mm, composition 1: 1.6 and pressure 3.5 bar.

Analisis regresi adalah suatu metode analisis statistik yang digunakan untuk mengetahui pengaruh antara dua atau lebih variabel. Model regresi yang sering digunakan dalam penelitian adalah model regresi berganda, yaitu model regresi dengan lebih dari satu variabel penjelas. Ada beberapa asumsi yang harus dipenuhi dalam regresi berganda, salah satunya adalah variansi dari error konstan (homoskedastisitas). Apabila variansi error tidak konstan (heterokedastisitas) maka menggunakan metode regresi terboboti. Model regresi yang melibatkan pengaruh heterogenitas spasial ke dalam model adalah model Regresi Terboboti secara Geografis (RTG). Jika data yang akan digunakan pada analisis regresi diperoleh dari lokasi-lokasi yang berbeda maka data tersebut disebut data spasial. Tujuan dari penelitian ini adalah untuk mengaplikasikan model RTG yang diterapkan pada kasus tingkat kesejahteraan penduduk di Kabupaten Banjar. Penelitian ini bersifat studi kasus dengan variabel respon banyaknya penduduk miskin yang terkategori PMKS dan variabel penjelas yaitu kepadatan penduduk, jumlah fasilitas pendidikan untuk SDN, SMP dan SMA, serta jumlah potensi desa untuk pekerja sosial masyarakat, organisasi sosial dan karang taruna. Hasil penelitian ini menunjukkan bahwa tidak semua variabel penjelas memberikan pengaruh terhadap banyaknya penduduk miskin yang terkategori PMKS. Sebanyak 74% kecamatan di Kabupaten Banjar menyatakan banyaknya penduduk miskin yang terkategori PMKS tidak dipengaruhi oleh variabel penjelas yang diduga dan sebanyak 21% kecamatan dipengaruhi oleh satu variabel penjelas. Sedangkan 5% kecamatan dipengaruhi oleh lima variabel bebas yang diduga.

Pasar valas merupakan pasar yang potensial untuk memperoleh keutungan finansial apabila dapat memprediksi pergerakan harga secara akurat pada masa yang akan datang. Pada penelitian ini dilakukan prediksi valas dengan mengkolaborasikan 2 algoritma yaitu Jaringan Syaraf Tiruan (JST) Backpropagation dan Moving Average Convergence Divergence (MACD). Ouput prediksi yang dihasilkan ada 3 yaitu Bearish (tren turun), Bullish (tren naik) dan Hold (tren netral). Tren turun dan tren naik dihasilkan apabila hasil prediksi JST dan MACD mempunyai sinyal tren yang sama, sedangkan tren netral dihasilkan apabila JST dan MACD mempunyai sinyal tren yang berbeda. Pada penelitian ini dilakukan prediksi harga penutupan pair USD/JPY setiap pukul 06.00 GMT selama 20 hari, data yang digunakan untuk training dan testing JST sebanyak 1440 data terdiri dari harga penutupan time frame 5 menit pukul 00.00 GMT hingga 05.55 GMT selama 20 hari sedangkan MACD menggunakan 560 data harga penutupan time frame 1 jam pukul 00.00 GMT hingga 23.00 GMT selama 20 hari. Dari 20 percobaan hasil kolaborasi (J-MACD) menghasilkan 12 sinyal hold, 5 transaksi sukses dan 3 transaksi gagal. Dengan demikian J-MACD mempunyai tingkat akurasi sebesar 62,5%.
