PENERAPAN MODEL PEMBELAJARAN TIPE MIND MAPPING UNTUK MENINGKATAN HASIL BELAJAR PESERTA DIDIK PADA MATA PELAJARAN BIOLOGI TENTANG SISTEM REGULASI DI KELAS XI IPA C SMA NEGERI 5 BOGOR
Authors: Retnowati Tri
Published: August 2019

Penelitian ini berangkat dari masih rendahnya daya serap siswa. Hal ini tampak dari hasil belajar peserta didik yang memprihatinkan. Rendahnya hasil belajar peserta didik disebabkan oleh proses pembelajaran yang konvensional. Pada proses pembelajaran cenderung teacher-centered sehingga peserta didik menjadi pasif, pendekatan abstrak dengan metode ceramah dan pemberian tugas, sangatlah dominan dari setiap kegiatan pembelajaran. Sangat jarang dijumpai guru menggunakan pendekatan nyata yang mengaktifkan peserta didik, karena guru menganggap pembelajaran yang demikian menyita waktu.
Penelitian ini bertujuan untuk: (1) mengetahui apakah melalui model pembelajaran mind mapping dapat meningkatkan hasil belajar biologi tentang sistem regulasi di kelas XI IPA C SMA Negeri 5 Bogor; (2) mendeskripsikan bagaimana proses peningkatan hasil belajar peserta didik dalam mata pelajaran biologi tentang sistem regulasi sebelum dan sesudah menggunakan model pembelajaran mind mapping di kelas XI IPA C SMA Negeri 5 Bogor; (3) mengukur seberapa besar peningkatan hasil belajar peserta didik sistem regulasi setelah menggunakan model pembelajaran mind mapping di kelas XI IPA C SMA Negeri 5 Bogor.
Bedasarkan hasil penelitian yang telah dilakukan tentang materi sistim regulasi, dapat diambil simpulan sebagai berikut: (1) Adanya peningkatan aktivitas dan hasil belajar peserta didik pada materi sistim regulasi di kelas XI IPA C SMA Negeri 5 Kecamatan Bogor Barat Kota Bogor dengan model pembelajaran mind mapping; (2) Penggunaan model pembelajaran mind mapping dalam pembelajaran membuat peserta didik tidak bosan dan jenuh sebaliknya merasa senang sehingga aktivitas belajar mereka meningkat. Hal ini terbukti pada pembelajaran. Setelah guru memperbaiki hasil refleksi pada siklus I maka pada siklus II didapat 84.38% atau 27 peserta didik aktif pada saat pembelajaran dan 15.63% atau 5 orang peserta didik yang cukup aktif pada saat pembelajaran serta 0,00% atau tidak ada peserta didik yang tidak aktif pada saat pembelajaran. Hal tersebut berpengaruh terhadap hasil belajar yang dicapai peserta didik; dan (3) Hasil belajar mata pelajaran sistem regulasi di kelas XI IPA C SMA Negeri 5 Kecamatan Bogor Barat Kota Bogor sebelum menggunakan model pembelajaran mind mapping mempunyai nilai rata-rata 64,69. Pada saat pembelajaran diubah menggunakan model pembelajaran mind mapping, rata-rata hasil belajar peserta didik meningkat menjadi 77,34 pada siklus I dan 82,50 pada siklus II.

Published: August 2019

Tulisan ini bertujuan untuk memberikan telaah kritis terhadap reposisi pelembagaan oposisi di parlemen berikut penguatan fungsi kontrol terhadap parlemen itu sendiri oleh masyarakat sipil. Dinamika sistem politik pasca orde baru mendesak terciptanya tatanan mekanisme checks and balances yang mampu mengakomodir peliknya persoalan tata kelola kebijakan publik dalam sistem presidensial dengan parlemen multi parpol ini. Tulisan ini dengan studi deskriptif analitis. Sumber data diperoleh dari referensi tentang partai politik dan pemilu serta relasi kuasa antar kekuatan politik. Tulisan ini mengambil setting celah parlemen yang membutuhkan kehadiran lembaga kontrol terhadap fungsi penyeimbang kekuasaan eksekutif sebagai konsekuensi dari pengejawantahan kewenangan yang cenderung dilematis. Penulis menyimpulkan bahwa jejaring masyarakat sipil dapat menjadi alternatif dominan untuk menjalankan peran pengawasan terhadap kinerja legislatif di parlemen. Ketika eksekutif secara konstitusional tak terlalu mampu mengimbangi fungsi pengawasan parlemen, maka reposisi organisasi masyarakat sipil yang dianggap sebagai representasi utuh dan ideal dari kepentingan masyarakat banyak, menjadi pilihan terbaik untuk meredam menguatnya demokrasi kolusif. Sinkronisasi regulasi, niat baik dari partai politik, peran control masyarakat civil, dan sinergisasi cara pandang terhadap konsekuensi sistem multipartai yang tumbuh menjadi dasar demokratisasi yang lebih maju.

Fourier Transform Infrared Spectroscopy as A Technique for Multivariate Analysis of Lard Adulteration in Food Products: A Review
Authors: Harun Farah Wahida
Published: August 2019

The presence of lard in food products is prohibited (haram) for Muslim and a few other religions i.e. Judaism and Hinduism. Due to the advantages of lard such as easily available, cheap and able to produce better quality of food products, the adulteration of food products with lard has become a serious issue. The complex composition of food products and similar properties of lard as an adulterant make identification of food adulterations a big challenge. Chemical analysis is one way to authenticate the halal status of the food products which is based on the specific markers present or absent in the products they contain. This article highlights on the use ofFourier transform infrared (FTIR) spectroscopy to determine the presence of lard combined with multivariate analysis. This technique also able to quantify the amount of lard in the food products that are claimed to be halal.

Influence of Sound-Absorbing Material Placement on Room Acoustical Parameters
Authors: Cucharero Jose , Hänninen Tuomas , Lokki Tapio
Published: August 2019

The reverberation of a room is often controlled by installing sound absorption panels to the ceiling and on the walls. The reduced reverberation is particularly important in classrooms to maximize the speech intelligibility and in open-plan offices to make spaces more pleasant. In this study, the impact of the placement of the absorption material in a room was measured in a reverberation room and in a mockup classroom. The results show that absorption material is less efficient if it is mounted to the corners or on the edges between the walls and ceiling, if the sound field is more or less diffuse. If the room modes dominate the sound field, the most efficient location for the sound-absorbing material was found at one of the surfaces causing the modes. The results help acoustical consultants to place the absorption material in optimal locations and, generally, minimize the amount of material and save costs.

Published: August 2019

Copy number variation (CNV) caused by gene rearrangement is an important part of genomic structural variation. We found that the copy number variation region of the Src Homology 2 Domain Containing E (SHE) gene correlates with a quantitative trait locus of sheep related to milk fat percentage and bone density. The aim of our study was to detect the copy number variation of the SHE gene in four sheep breeds and to conduct a correlation analysis with economic traits, hoping to provide some reference for sheep breeding. In this study, we examined 750 sheep from four Chinese breeds: Chaka sheep (CKS), Hu sheep (HS), Large Tail Han sheep (LTHS) and Small Tail Han sheep (STHS). We used qPCR to evaluate the copy number of the SHE gene, and then used general linear models to analyze the associations between CNV and economic traits. The results showed that there were more individuals with SHE copy number loss in CKS and HS than in STHS and LTHS individuals. Association analyses showed that gain and normal copy number types were correlated to body length, circumference of cannon bone, heart girth, chest width and high at the cross in CKS, HS and STHS (p < 0.05), but this association was not observed for LTHS. Chi-square values (χ2) found prominent differences in CNV distribution among the studied breeds. Overall, the CNV of the SHE gene may be an important consideration for sheep molecular breeding.

Published: August 2019

The aim of this research was to evaluate the possible usefulness of mirrors in improving rabbit behavior in a free-range breeding system. Three groups (each consisting of nine replicates of three animals) were compared: isolated, isolated with mirrors and separated by a wire mesh (possible visual and olfactory contacts). Rabbits allowed to have a visual and olfactory contact showed a significantly higher expression of important natural behaviors (olfactory investigation, gnawing, alertness, stretching, locomotion) compared to the isolated rabbits (with or without mirrors); while rabbits in the mirror group showed higher allo-grooming activity than those isolated and no different locomotion activity than those separated by wire mesh. Thus, mirrors seemed to be able to modify the behavioral repertoire of isolated rabbits by acting on social perception in rabbits reared in small groups in a free-range system. Nevertheless, despite it being advisable to use a combination of different indicators in order to assess the stress level of an animal, the accuracy of serum cortisol, as well as of some secondary stress markers assay, appeared to be limited in this type of breeding.

Supplementation of livestock and poultry diets with herbal plants containing bioactive components have shown promising reports as natural feed supplements. These additives are able to promote growth performance and improve feed efficiency, nutrient digestion, antioxidant status, immunological indices, and poultry health. Several studies have used complex herbal formulas with the partial inclusion of licorice. However, the individual use of licorice has been rarely reported. The major problem of the poultry industry is the epidemiological diseases, mainly confined to the respiratory, digestive, and immune systems. Licorice has certain bioactive components such as flavonoids and glycyrrhizin. The roots of this herb contain 1 to 9% glycyrrhizin, which has many pharmacological properties such as antioxidant, antiviral, anti-infective and anti-inflammatory properties. Licorice extracts (LE) have a positive effect on the treatment of high-prevalence diseases such as the immune system, liver, and lung diseases. Studies showed that adding LE to drinking water (0.1, 0.2, or 0.3 g/L) reduced serum total cholesterol (p < 0.05) of broiler chickens. Moreover, LE supplementation in poultry diets plays a significant role in their productive performance by enhancing organ development and stimulating digestion and appetite. Along with its growth-promoting effects, licorice has detoxifying, antioxidant, antimicrobial, anti-inflammatory, and other health benefits in poultry. This review describes the beneficial applications and recent aspects of the Glycyrrhiza glabra (licorice) herb, including its chemical composition and role in safeguarding poultry health.

Authors: Arroyo Citlalli Adelaida , Contreras José Luis , Zeifert Beatriz , Ramírez C. Clementina
Published: August 2019

A process composed by a catalytic converter and three sequential Airlift photobioreactors containing the microalga Scenedesmus dimorphus was studied to capture CO2, NOx, and CO from emissions of a steam boiler which was burning diesel. The catalytic converter transformed to CO2 a maximum of 78% of the CO present in the combustion gas. The effects of shear rate, light intensity, and light/dark cycles on the biomass growth of the algae were studied. It was observed that at low shear rates (Re ≈ 3200), a high productivity of 0.29 gcel L−1 d−1 was obtained. When the microalga was exposed to 60.75 µmol·m−2·s−1 of intensity of light and a light/dark cycle of 16/8 h, a maximum productivity of 0.44 gcel L−1 d−1 and a maximum CO2 fixation rate 0.8 g CO2 L−1·d−1 were obtained. The maximum CO2 removal efficiency was 64.3%, and KLa for CO2 and O2 were 1.2 h−1 and 3.71 h−1 respectively.

What Does a Hand-Over Tell?—Individuality of Short Motion Sequences
Authors: Bekemeier Holger , Maycock Jonathan , Ritter Helge
Published: August 2019

How much information with regard to identity and further individual participantcharacteristics are revealed by relatively short spatio-temporal motion trajectories of a person?We study this question by selecting a set of individual participant characteristics and analysingmotion captured trajectories of an exemplary class of familiar movements, namely handover of anobject to another person. The experiment is performed with different participants under different,predefined conditions. A selection of participant characteristics, such as the Big Five personalitytraits, gender, weight, or sportiness, are assessed and we analyse the impact of the three factor groups“participant identity”, “participant characteristics”, and “experimental conditions” on the observedhand trajectories. The participants’ movements are recorded via optical marker-based hand motioncapture. One participant, the giver, hands over an object to the receiver. The resulting time courses ofthree-dimensional positions of markers are analysed. Multidimensional scaling is used to projecttrajectories to points in a dimension-reduced feature space. Supervised learning is also applied.We find that “participant identity” seems to have the highest correlation with the trajectories, withfactor group “experimental conditions” ranking second. On the other hand, it is not possible to find acorrelation between the “participant characteristics” and the hand trajectory features.
An Analysis of Eco-Technology Allowing Water and Energy Saving in an Environmentally Friendly House—A Case Study from Poland
Authors: Stec Agnieszka , Mazur Aleksandra
Published: August 2019

The Life Cycle Cost (LCC) analysis on selected alternative systems was carried out to reduce the demand for potable water and energy in a detached house designed in accordance with the concept of environmentally friendly house. The tests included a rainwater harvesting system, graywater recycling system, solar panels, photovoltaic panels, air heat pumps, ground heat pumps, wind turbines, drain water heat recovery units, and biomass boilers. The analysis was made for many investment variants where different combinations of the mentioned solutions were applied. In addition to the LCC analysis, some tests were also carried out to determine an impact of the investment options on the environment. This was done by calculating CO2, SO2, NOx, CO and dust emissions. The research was carried out for a different number of occupants and variable levels of water consumption, which allowed determining the impact of these parameters on the results obtained. They showed that for any of the computational cases the traditional option of the installation was not the most advantageous solution in financial and environmental terms, and the systems in question could be an alternative to this option. Thanks to their implementation, the consumption of fossil energy resources and natural water resources will be reduced, and the emission of pollutants will be limited, which will contribute to an improvement of the natural environment.
CSCs in Breast Cancer—One Size Does Not Fit All: Therapeutic Advances in Targeting Heterogeneous Epithelial and Mesenchymal CSCs
Authors: Sulaiman Andrew , McGarry Sarah , Han Xianghui , Liu Sheng , Wang Lisheng
Published: August 2019

Unlike other breast cancer subtypes, triple-negative breast cancer (TNBC) has no specific targets and is characterized as one of the most aggressive subtypes of breast cancer that disproportionately accounts for the majority of breast cancer-related deaths. Current conventional chemotherapeutics target the bulk tumor population, but not the cancer stem cells (CSCs) that are capable of initiating new tumors to cause disease relapse. Recent studies have identified distinct epithelial-like (E) ALDH+ CSCs, mesenchymal-like (M) CD44+/CD24− CSCs, and hybrid E/M ALDH+/CD44+/CD24− CSCs. These subtypes of CSCs exhibit differential signal pathway regulations, possess plasticity, and respond differently to treatment. As such, co-inhibition of different subtypes of CSCs is key to viable therapy. This review serves to highlight different pathway regulations in E and M CSCs in TNBC, and to further describe their role in disease progression. Potential inhibitors targeting E and/or M CSCs based on clinical trials are summarized for further investigation. Since future research needs to adopt suitable tumor models and take into account the divergence of E and M CSCs for the development of effective treatments, TNBC models for clinically translatable studies are further discussed.

Published: August 2019

Desulfurization processes play an important role in the use of biogas in the emerging market of renewable energy. In this study, an iron-redox biological process was evaluated at bench scale and pilot scale to remove hydrogen sulfide (H2S) from biogas. The pilot scale system performance was assessed with real biogas emitted from a closed landfill to determine the desulfurization capacity under outdoor conditions. The system consisted of an Absorption Bubble Column (ABC) and a Biotrickling Filter (BTF) with useful volumes of 3 L and 47 L, respectively. An acidophilic mineral-oxidizing bacterial consortium immobilized in polyurethane foam was utilized to regenerate Fe(III) ion, which in turn accomplished the continuous H2S removal from inlet biogas. The H2S removal efficiencies were higher than 99.5% when H2S inlet concentrations were 120–250 ppmv, yielding a treated biogas with H2S < 2 ppmv. The ferrous iron oxidation rate (0.31 g·L−1·h−1) attained when the system was operating in natural air convection mode showed that the BTF can operate without pumping air. A brief analysis of the system and the economic aspects are briefly analyzed.

Authors: Le Borgne Sylvie , Baquerizo Guillermo
Published: August 2019

Bacterial communities’ composition, activity and robustness determines the effectiveness of biofiltration units for the desulfurization of biogas. It is therefore important to get a better understanding of the bacterial communities that coexist in biofiltration units under different operational conditions for the removal of H2S, the main reduced sulfur compound to eliminate in biogas. This review presents the main characteristics of sulfur-oxidizing chemotrophic bacteria that are the base of the biological transformation of H2S to innocuous products in biofilters. A survey of the existing biofiltration technologies in relation to H2S elimination is then presented followed by a review of the microbial ecology studies performed to date on biotrickling filter units for the treatment of H2S in biogas under aerobic and anoxic conditions.

Transparent conductive films are fundamental materials, currently used in several fields. Recently, due to their unique multifunctional properties, composite materials have started to be used in place of fluorine tin oxide and indium tin oxide in transparent conductive electrodes. However, the production of composite materials is still complicated and involves toxic chemicals. Through a simple and environmentally-friendly method, we synthesized new composite materials—conductive, transparent, and flexible films—that can be applied to the production of modern optoelectronic devices. An even dispersion of the nanoparticles was achieved by ultrasound excitation. Moreover, a series of morphological and structural investigations were conducted on the films by scanning and transmission electron microscopy, electrical conductivity, Raman spectroscopy, X-ray diffraction and testing their sheet resistance. The results indicated that the tested composite materials were ideal for film coating. The nanofluids containing multi-walled carbon nanotubes presented the highest electrical conductivity; nevertheless, all the composite nanofluids tended to have relatively high electrical conductivities. The flexible films with composite structures presented lower sheet resistances than those with single structures. Finally, the hybrid materials showed a higher transmittance.

Calcined layered double hydroxides (LDHs) can be used to remove Sb(V), in the Sb(OH)6− form, from aqueous solutions. Sorption batch experiments showed that the mixed MgAlFe oxides, obtained from calcined hydrotalcite-like compound (3HT-cal), removed Sb(OH)6− through the formation of a non-LDH brandholzite-like compound, whereas the mixed ZnAl oxides, resulting from calcined zaccagnaite-like compound (2ZC-cal), trapped Sb(OH)6− in the interlayer during the formation of a Sb(V)-bearing LDH (the zincalstibite-like compound). The competition effect of coexistent anions on Sb(OH)6− removal was HAsO42− >> HCO3− ≥ SO42− for 2ZC-cal and HAsO42− >> HCO3− >> SO42− for 3HT-cal. Considering the importance of assessing the practical use of calcined LDHs, batch experiments were also carried out with a slag drainage affected by serious Sb(V) pollution (Sb = 9900 μg/L) sampled at the abandoned Su Suergiu mine (Sardinia, Italy). Results showed that, due to the complex chemical composition of the slag drainage, dissolved Sb(OH)6− was removed by intercalation in the interlayer of carbonate LDHs rather than through the formation of brandholzite-like or zincalstibite-like compounds. Both 2ZC-cal and 3HT-cal efficiently removed very high percentages (up to 90–99%) of Sb(V) from the Su Suergiu mine drainage, and thus can have a potential application for real polluted waters.

The modification of CD4+ T cells with exogenous nucleic acids or proteins is a critical step in several research and therapeutic applications, such as HIV studies and cancer immunotherapies. However, efficient cell transfections are not always easily achieved when working with these primary hard-to-transfect cells. While the modification of T cells is typically performed by viral transduction or electroporation, their use is associated with safety issues or cytotoxicity. Vapor nanobubble (VNB) photoporation with sensitizing gold nanoparticles (AuNPs) has recently emerged as a new technology for safe and flexible cell transfections. In this work, we evaluated the potential of VNB photoporation as a novel technique for the intracellular delivery of macromolecules in primary human CD4+ T cells using fluorescent dextrans as model molecules. Our results show that VNB photoporation enables efficient delivery of fluorescent dextrans of 10 kDa in Jurkat (>60% FD10+ cells) as well as in primary human CD4+ T cells (±40% FD10+ cells), with limited cell toxicity (>70% cell viability). We also demonstrated that the technique allows the delivery of dextrans that are up to 500 kDa in Jurkat cells, suggesting its applicability for the delivery of biological macromolecules with a wide range of molecular weights. Altogether, VNB photoporation represents a promising technique for the universal delivery of macromolecules in view of engineering CD4+ T cells for use in a wide variety of research and therapeutic applications.
Load Areas in Radial Unbalanced Distribution Systems

Published: August 2019

The demand becoming flexible is a requirement for the full exploitation of renewable energy sources. Aggregation may foster the provision of flexibility by small-scale providers connected to distribution grids, since it allows offering significant flexibility volumes to the market. The aggregation of flexibility providers is carried out by the aggregator, a new market role and possibly a new market player. Location information of individual flexibility providers is necessary for both the aggregator and the system operators, in particular, the Distribution System Operator (DSO). For the former, information should allow treating a high number of individual flexibility providers as a single provider to offer significant flexibility volumes to the markets; for the latter, the information should ensure an adequate visibility of the connection of the individual providers to the grid. In the paper, the concept of Load Area (LA) is recalled, which combines the needs of location information of the aggregator and of the DSO. A method for the identification and modeling of LAs for the general case of unbalanced radial systems is proposed. The results of the methods’ application to two studied unbalanced networks are presented, showing the effectiveness and viability of the proposed approach.

The distance between theory and practice in the strategic environmental assessment (SEA) process is particularly noticeable. The development of an integrated, comprehensive and systematic approach guided by the related literature is considered to be an ideal condition for enhancing the value of SEA and increasing its effectiveness. The aim of the present paper was to develop a methodological approach of the most technical and critical stages of SEA for onshore wind farm (OWF) siting. The methodological framework included the proposal of the SEA objectives along with the indicators’ development, the identification of alternatives, the selection of a ‘most viable or sustainable’ alternative, the identification of potential impacts, their assessment, and finally, the proposal of a SEA monitoring system using both qualitative and quantitative methods, tools, and techniques. OWF siting within low and/or moderate sensitivity areas was considered as the most viable/sustainable alternative. SEA highlighted that OWF siting caused moderately to highly significant negative impacts on the thematic section of biodiversity and extremely significant positive impacts on the thematic sections of renewable energy sources, economy, and society. Although the proposed methodology was applied on SEA of OWF siting in Greece, it can be used universally to identify the impacts of OWF siting planning.

The accurate estimation of leaf area is of great importance for the acquisition of information on the forest canopy structure. Currently, direct harvesting is used to obtain leaf area; however, it is difficult to quickly and effectively extract the leaf area of a forest. Although remote sensing technology can obtain leaf area by using a wide range of leaf area estimates, such technology cannot accurately estimate leaf area at small spatial scales. The purpose of this study is to examine the use of terrestrial laser scanning data to achieve a fast, accurate, and non-destructive estimation of individual tree leaf area. We use terrestrial laser scanning data to obtain 3D point cloud data for individual tree canopies of Pinus massoniana. Using voxel conversion, we develop a model for the number of voxels and canopy leaf area and then apply it to the 3D data. The results show significant positive correlations between reference leaf area and mass (R2 = 0.8603; p < 0.01). Our findings demonstrate that using terrestrial laser point cloud data with a layer thickness of 0.1 m and voxel size of 0.05 m can effectively improve leaf area estimations. We verify the suitability of the voxel-based method for estimating the leaf area of P. massoniana and confirmed the effectiveness of this non-destructive method.
