Authors: Agustini Rika Yayu
Published: November 2018

This study aims to determine the optimal dosage of bottom ash and organic matter which can increase the growth and yield of mustard plants. The study was carried out in the greenhouse of the Soil Physics Laboratory, Balai Penelitian Tanah, Laladon, Bogor from August 2015 to January 2016. The study used factorial complete randomized design (CRD). The first factor is the age of bottom ash (fresh, 4 months and 2 years). The second factor is the bottom ash dose with three levels, which are 0, 60 and 120 grams / pot (equivalent to 0, 40 and 80 tons / ha) and the third factor is the dose of organic matter with two levels, namely 0 and 15 grams / pot (equivalent to 0 and 10 tons / ha). The results showed that the addition of fresh bottom ash with a dose of 80 tons / ha and 10 tons / ha of organic matter significantly affected the plant height. While on the parameters of the number of leaves and fresh weight of mustard plant, the treatment that gives a significant effect is 10 tons / ha of organic matter. The best dose that can increase the growth and yield of mustard plants is fresh bottom ash with a dose of 80 tons / ha and 10 tons / ha of organic matter.

There are several ways to create good  soil conditions to support plant growth in acid soils, such as the addition of mycorrhiza. The objective of the study was to increase the growth and production of Bangka local cassava in acid soils. The experiment had been conducted on acid soils with pH 4.4 (very acidic) and P-Bray 1 5.8 ppm (very low) in Balunijuk Village, Bangka Regency, from September 2016 - May 2017. This research used the experiment method with factorial randomized block design (FRBD) with two factors. The first factor was Bangka local cassava namely Sutera, Mentega, Batin, 3 Bulan and Malang variety (as the comparison) and second factor was mycorrhiza. The results showed Sutera accession had the highest plant height and production in acid soils. The addition of mycorrhiza as much as 50 g / plant can increase the growth and production of Bangka local cassava. The Bangka local cassava showed  better growth quality but still have lower production compared with national varieties. Conservation of local cassava plants Bangka in acid soils can be optimized its growth by using local clones Bangka, but the production of national varieties is higher compared local cassava of Bangka

Arah pembangunan dewasa ini tentunya tidak semata mengarah pada pembangunan fisik semata, melainkan lebih dari itu pembangunan manusia secara menyeluruh. Mulai dari aspek ekonomi, pendidikan, perkembangan teknologi, peningkatan akses kesehatan, peningkatan dalam infrastruktur yang tersedia dan peningkatan dalam pendapatan serta kemakmuran masyarakat. Sesuai dengan amanat UU 52/2009, maka salah satu wujud konkrit dalam pembangunan manusia adalah melalui Pembentukan Kampung KB. Program kampung KB merupakan salah satu program pemerintah dalam agenda prioritas pembangunan Nawacita sebagai bagian dari penguatan program KKBPK. Tulisan ini akan menjelaskan kontribusi Kampung KB sejak dicanangkan tahun 2016 di Kabupaten Jombang dalam upaya peningkatan program KKBPK yang didalamnya terdapat beberapa indikator antara lain peningkatan jumlah akseptor KB baru, terlayaninya kesehatan ibu hamil dan menyusui, remaja aktif dalam kegiatan BKR dan PIK, penurunan angka buta aksara, meningkatnya partisipasi keluarga pra sejahtera dan KS-1 dalam program UPPKS. Metode yang digunakan melalui pendekatan deskriptif kualitatif dengan metode eksplorasi pada 3 wilayah Kampung KB yang tersebar di Kabupaten Jombang. Hasilnya, secara umum keberadaan Kampung KB berkontribusi secara signifikan pada penguatan program KKBPK, namun kontribusi tersebut dirasa belum maksimal mengingat masih kuatnya ego sektoral diantara stakeholder terkait program maupun anggaran, sehingga dibutuhkan political will dan model sinergitas antar stakeholder yang ada tersebut. Selain itu, perencanaan yang partisipatif dari masyarakat dan pemberdayaan potensi yang ada menjadi salah satu kunci keberhasilan program Kampung KB.

Published: November 2018

Gejala Flu Burung ( Avian Influezsa) di Kabupaten Blitar telah dimulai sejak akhir tahun 2003. Namun saat itu masyarakat maupun aparat setempat belum menyadari adanya wabah tersebut. Baru setelah awal tahun 2004 diketahui bahwa wabah Avian Influenza (AI) banyak menyerang ternak unggas diwilayah ini dan puncak serangan terjadi pada bulanbulan Februari sampai dengan April 2004.  Selama kurun waktu 3(tiga) bulan tersebut tidak kurang dari 7,48 juta ekor ayam ras mati karena wabah flu burung maupun sebagai akibat adanya depopulasi. Pada saat terjadinya wabah Afian Influenza di  Kabupaten Blitar, keadaan tersebut sedikit banyak berpengaruh terhap harga-harga produk ternak unggas. Kontraksi harga tersebut tidak terlalu berdampak terhadap perkembangan harga input maupun harga output produk untuk periode selanjutnya. Intensitas kegiatan penanggulangan wabah AI tampaknya mampu meredam gejolak fluktuasi harga produk pada tahun yang bersangkutan, sehingga harga produk ternak ungggas kembali menjadi normal. Tulisan ini merupakan hasil pengamatan dilapangan yang dilakukan pada tahun 2006 di wilayah Kabupaten Blitar, Jawa Timur.

Published: November 2018

Competition requires every organization to increase the quality in their competitiveness by using high quality and competent human resources. The competency should be beyond academic and working skills alone, and should include attitude as well. Inefficient quality and competency of human resources results in declination of work effectiveness. The goal of this research is to elicit whether there is positive impact on the increase of competency toward working effectiveness. The object of this research is employees at the Secretariate Directorate General of Human Resources and Post and Informatic Devices (Secretariat General SDPPI). Variable indicator of the competence studies includes knowledge, ability and attitude. Data analysis to test the hypothesis is done using multiple linear regression, determination coefficient, F-test and T-test analysis. From the three independent variables that were individually tested, the most dominant compensation that affects work effectiveness of workers is knowledge, with a coefficient of 0.366. F-test analysis showed that knowledge, ability and attitude, all together has positive effect toward workers’ work effectiveness.

Hard Objects in George Oppen's Discrete Series
Authors: Hercock Ned
Published: November 2018

This essay examines the objects in George Oppen's Discrete Series (1934). It considers their primary property to be their hardness – many of them have distinctively uniform and impenetrable surfaces. This hardness and uniformity is contrasted with 19th century organicism (Gerard Manley Hopkins and John Ruskin). Taking my cue from Kirsten Blythe Painter I show how in their work with hard objects these poems participate within a wider cultural and philosophical turn towards hardness in the early twentieth century (Marcel Duchamp, Adolf Loos, Ludwig Wittgenstein and others). I describe the thinking these poems do with regard to industrialization and to human experience of a resolutely object world – I argue that the presentation of these objects bears witness to the production history of the type of objects which in this era are becoming preponderant in parts of the world. Finally, I suggest that the objects’ impenetrability offers a kind of anti-aesthetic relief: perception without conception. If ‘philosophy recognizes the Concept in everything’ it is still possible, these poems show, to experience resistance to this imperious process of conceptualization. Within thinking objects (poems) these are objects which do not think.

Published: November 2018

The present study assessed the effect of dietary supplementation with coconut oil (CNO), watercress oil (WCO), and their mixture as promoters of growth, antioxidant status, immunity, and intestinal microbiota in growing rabbits. A total of 120 rabbits were distributed into six groups (20 rabbits/group) receiving a basal diet without supplementation (G1) or diet supplemented with 2 g CNO (G2), 2 g WCO (G3), 0.5 g CNO plus 1.5 g WCO (G4), 1 g CNO plus 1 g WCO (G5), or 1.5 g CNO plus 0.5 g WCO/kg (G6). Live body weight and feed conversion ratio were significantly higher in the G4 and G5 groups than in the other groups. Superoxide dismutase activity and reduced glutathione concentration were significantly improved in the CNO or WCO diets. Supplemental CNO plus WCO at all tested levels produced the best lysozyme and complement 3 activities. Cecal lactobacilli, coliform, Enterobacteriaceae, and Clostridium spp. populations were lower in the group who received the 1 g CNO + 1 g WCO/kg diet than that in the control group. Dietary supplementation of 1 g CNO + 1 g WCO or 0.5 g CNO + 1.5 g WCO/kg had the potential to improve growth, feed utilization, antioxidant status, and immunity, and reduce cecal pathogenic bacteria in rabbits.
The Impact of ‘Selfie’ Tourism on the Behaviour and Welfare of Brown-Throated Three-Toed Sloths
Authors: Carder Gemma , Plese Tinka , Machado Fernando Carniel , Paterson Suzanne , Matthews Neil , McAnea Laura , D’Cruze Neil
Published: November 2018

The use of wild animals as photo props is prevalent across the globe and is widely recognised to represent a potential animal welfare concern. However, detailed information regarding the specific impacts of such activity on wild animal behaviour is currently lacking. Herein, we investigated how brown-throated three-toed sloths (Bradypus variegatus) were handled by tourists, and how sloths behaved during wildlife ‘selfies’ taken in Manaus, Brazil and Puerto Alegria and Iquitos in Peru. In total, we observed 17 sloths (during 70 focal observations) that were provided for use in wildlife selfies on 34 different tours. We found that an average number of 5 people held each sloth during each focal observation. For 48.6% of the time the sloths were handled in a way which involved physical manipulation of the sloths’ head and/or limbs and/or being held by the claws. From the eight different types of sloth behaviour observed, we found that the two types performed for the longest average duration of time were surveillance (55.3%) and limb stretching (12.6%). Our findings show that when being handled sloths were frequently held in ways that may compromise their welfare. Although to date the behaviour of sloths while being handled has not been reported in any published literature, in this study we document certain behaviours which may act as indicators of compromised welfare. We suggest that our data provides a potential baseline for future study into the behaviour and welfare of sloths.
Asymptotic Analysis for the Effects of Anode Inlet Humidity on the Fastest Power Attenuation Single Cell in a Vehicle Fuel Cell Stack
Authors: Liu Yongfeng , Gao Jianhua , Wang Na , Yao Shengzhuo
Published: November 2018

A three-dimensional and isothermal anode relative humidity (ARH) model is presented and used to study the anode inlet humidity effects on the fastest power attenuation single cell in a vehicle fuel cell stack. The ARH model is based on the phenomenon that the anode is more sensitive than the cathode to water flooding. The pressure drop is considered in the ARH model, and saturation pressure is established by a pressure drop. Based on the pressure drop and relative humidity, simulations and tests are completed. First, the geometric model and computational grids are established, based on real structure of the proton exchange membrane fuel cell (PEMFC). Second, single cell distribution in the stack, test schematic and experimental conditions are demonstrated. Finally, polarization curves with 10 cells are displayed and discussed under these conditions that working temperature 70 °C, and diverse relative humidity (40%, 55%, 70%, 85%, and 100%). The test results of 34 cm2 fuel cell stack are compared against simulation results. The results show that C10 (the single cell with the farthest distance from the gas inlet) power attenuation is the fastest and that its performance is the poorest under the experimental conditions. The polarization curves predicted by the ARH model indicate fairly good coherence with the experimental results, compared against the Fluent original model. The ARH model calculation deviation is 28% less than the Fluent model at 360 mA·cm−2 for a relative humidity of 85%. The current density distribution is almost uniform, and membrane water content is negatively affected by high humidity.
Borderline Personality Disorder (BPD): In the Midst of Vulnerability, Chaos, and Awe
Authors: Kulacaoglu Filiz , Kose Samet
Published: November 2018

Borderline personality disorder (BPD) is a chronic psychiatric disorder characterized by pervasive affective instability, self-image disturbances, impulsivity, marked suicidality, and unstable interpersonal relationships as the core dimensions of psychopathology underlying the disorder. Across a wide range of situations, BPD causes significant impairments. Patients with BPD suffer considerable morbidity and mortality compared with other populations. Although BPD is more widely studied than any other personality disorder, it is not understood sufficiently. This paper briefly reviews the recent evidence on the prevalence, etiology, comorbidity, and treatment approaches of borderline personality disorder (BPD) by examining published studies, and aims to offer a more coherent framework for the understanding and management of borderline personality disorder.
Aberrant RNA Splicing in Cancer and Drug Resistance
Authors: Wang Bi-Dar , Lee Norman
Published: November 2018

More than 95% of the 20,000 to 25,000 transcribed human genes undergo alternative RNA splicing, which increases the diversity of the proteome. Isoforms derived from the same gene can have distinct and, in some cases, opposing functions. Accumulating evidence suggests that aberrant RNA splicing is a common and driving event in cancer development and progression. Moreover, aberrant splicing events conferring drug/therapy resistance in cancer is far more common than previously envisioned. In this review, aberrant splicing events in cancer-associated genes, namely BCL2L1, FAS, HRAS, CD44, Cyclin D1, CASP2, TMPRSS2-ERG, FGFR2, VEGF, AR and KLF6, will be discussed. Also highlighted are the functional consequences of aberrant splice variants (BCR-Abl35INS, BIM-γ, IK6, p61 BRAF V600E, CD19-∆2, AR-V7 and PIK3CD-S) in promoting resistance to cancer targeted therapy or immunotherapy. To overcome drug resistance, we discuss opportunities for developing novel strategies to specifically target the aberrant splice variants or splicing machinery that generates the splice variants. Therapeutic approaches include the development of splice variant-specific siRNAs, splice switching antisense oligonucleotides, and small molecule inhibitors targeting splicing factors, splicing factor kinases or the aberrant oncogenic protein isoforms.

Published: November 2018

Current genomic models in diffuse large B-cell lymphoma (DLBCL) are based on single tumor biopsies, which might underestimate heterogeneity. Data on mutational evolution largely remains unknown. An exploratory study using whole exome sequencing on paired (primary and relapse) formalin fixed paraffin embedded DLBCL biopsies (n = 14) of 6 patients was performed to globally assess the mutational evolution and to identify gene mutations specific for relapse samples from patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. A minority of the mutations detected in the primary sample (median 7.6%, range 4.8–66.2%) could not be detected in the matching relapse sample. Relapsed DLBCL samples showed a mild increase of mutations (median 12.5%, range 9.4–87.6%) as compared to primary tumor biopsies. We identified 264 genes possibly related to therapy resistance, including tyrosine kinases (n = 18), (transmembrane) glycoproteins (n = 73), and genes involved in the JAK-STAT pathway (n = 7). Among the potentially resistance related genes were PIM1, SOCS1, and MYC, which have been reported to convey a risk for treatment failure. In conclusion, we show modest temporal heterogeneity between paired tumor samples with the acquisition of new mutations and identification of genes possibly related to therapy resistance. The mutational evolution could have implications for treatment decisions and development of novel targeted drugs.

Published: November 2018

This review summarizes recent progress in the development of cobalt-based catalytic centers as the most potentially useful alternatives to noble metal-based electrocatalysts (Pt-, Ir-, and Ru-based) towards the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) in acid and alkaline media. A series of cobalt-based high-performance electrocatalysts have been designed and synthesized including cobalt oxides/chalcogenides, Co–Nx/C, Co-layered double hydroxides (LDH), and Co–metal-organic frameworks (MOFs). The strategies of controllable synthesis, the structural properties, ligand effect, defects, oxygen vacancies, and support materials are thoroughly discussed as a function of the electrocatalytic performance of cobalt-based electrocatalysts. Finally, prospects for the design of novel, efficient cobalt-based materials, for large-scale application and opportunities, are encouraged.

Corynebacterium glutamicum is an industrial strain used for the production of valuable chemicals such as L-lysine and L-glutamate. Although C. glutamicum has various industrial applications, a limited number of tunable systems are available to engineer it for efficient production of platform chemicals. Therefore, in this study, we developed a novel tunable promoter system based on repeats of the Vitreoscilla hemoglobin promoter (Pvgb). Tunable expression of green fluorescent protein (GFP) was investigated under one, four, and eight repeats of Pvgb (Pvgb, Pvgb4, and Pvgb8). The intensity of fluorescence in recombinant C. glutamicum strains increased as the number of Pvgb increased from single to eight (Pvgb8) repeats. Furthermore, we demonstrated the application of the new Pvgb promoter-based vector system as a platform for metabolic engineering of C. glutamicum by investigating 5-aminovaleric acid (5-AVA) and gamma-aminobutyric acid (GABA) production in several C. glutamicum strains. The profile of 5-AVA and GABA production by the recombinant strains were evaluated to investigate the tunable expression of key enzymes such as DavBA and GadBmut. We observed that 5-AVA and GABA production by the recombinant strains increased as the number of Pvgb used for the expression of key proteins increased. The recombinant C. glutamicum strain expressing DavBA could produce higher amounts of 5-AVA under the control of Pvgb8 (3.69 ± 0.07 g/L) than the one under the control of Pvgb (3.43 ± 0.10 g/L). The average gamma-aminobutyric acid production also increased in all the tested strains as the number of Pvgb used for GadBmut expression increased from single (4.81–5.31 g/L) to eight repeats (4.94–5.58 g/L).
Biochars and Their Use as Transesterification Catalysts for Biodiesel Production: A Short Review
Authors: Vakros John
Published: November 2018

Biodiesel can be a significant alternative for diesel. Usually, it is produced through transesterification with a base catalyst. Using heterogeneous catalysts for transesterification, the process can be more efficient. Among the possible catalysts that can be used, biochars combine high performance for transesterification and valorization of waste biomass. Biochars are cheap materials, and are easy to activate through chemical treatment with acid or base solutions. In this short review, the application of biochar as solid heterogeneous catalysts for transesterification of lipids to produce biodiesel is discussed.
Universality of Droplet Impingement: Low-to-High Viscosities and Surface Tensions
Authors: Yonemoto Yukihiro , Kunugi Tomoaki
Published: November 2018

When a droplet impinges on a solid surface, its kinetic energy is mainly converted to capillary energy and viscous dissipation energy, the ratio of which depends on the wettability of the target surface and the liquid properties. Currently, there is no experimental or theoretical evidence that suggests which types of liquids exhibit the capillary energy-dominated impingement behavior. In this paper, we reported the droplet impingement behavior for a wide range of liquid viscosities, surface tensions and target surface wettabilities. Then, we showed that a recently developed energy balance equation for the droplet impingement behavior can be universally employed for predicting the maximum spreading contact area diameter of a droplet for Newtonian liquids in deposition process by modelling the droplet surface deformation. Subsequently, applicability limitations of recent existing models are discussed. The newly developed model demonstrated that the capillary energy-dominated impingement behavior can be observed at considerably low viscosities of liquid droplets such as that of the superfluid of liquid helium.

The technological evolution in the last century also required an evolution of materials and coatings. Therefore, it was necessary to make mechanical components subject to heavy wear more reliable, improving their mechanical strength and durability. Surfaces can contribute decisively to extending the lifespan of mechanical components. Chemical vapor deposition (CVD) and physical vapor deposition (PVD) technologies have emerged to meet the new requirements that have enabled a remarkable improvement in the morphology, composition and structure of films as well as an improved adhesion to the substrate allowing a greater number of diversified applications. Thin films deposition using PVD coatings has been contributing to tribological improvement, protecting their surfaces from wear and corrosion, as well as enhancing their appearance. This process can be an advantage over other processes due to their excellent properties and environmental friendly behavior, which gives rise to a large number of studies in mathematical modelling and numerical simulation, like finite element method (FEM) and computational fluid dynamics (CFD). This review intends to contribute to a better PVD process knowledge, in the fluids and heat area, using CFD simulation methods focusing on the process energy efficiency improvement regarding the industrial context with the sputtering technique.

Using organic coatings helps to protect PET (polyethylene terephthalates) surfaces, improve surface hardness, scratch resistance, and solvent resistance, prolong the service life of PET film, and to expand their scope of applications. There were some disadvantages, including poor flexibility and impact resistance in high-hardness coatings; organic coatings should also be modified to improve the toughness. Herein, a UV (ultraviolet curing) curable high-hardness organic coating used in PET surface protection was prepared and modified with inorganic nanoparticles, such as OVPOSS (octavinyl-polyhedral oligomeric silsesquioxane). The effects of the categories of nanoparticles on the coating performance were studied. UV-Vis spectra (ultraviolet visible light spectra), FT-IR (Fourier transform infrared spectrometer), TGA (thermogravimetric analysis), DMA (dynamic-mechanical), SEM (field emission scanning electron microscope), and AFM (atomic force microscope) were used to characterize the properties of the coatings. The results showed that the addition of eight-vinyl POSS to the organic coating significantly increased its glass transition temperature (Tg) from 100 to 120 °C, improved its storage modulus from 167.6 to 258.9 MPa, and raised its impact resistance and flexibility. The SEM and AFM images displayed that the eight-vinyl POSS particles were dispersed homogeneously in the coating, arranged in an ordered network, and had good compatibility with organic components. The film displayed excellent properties, including 4 H of the pencil hardness, 100 g cm of impact resistance, excellent flexibility, and 90% of light transmittance, with the addition of 0.3 wt % OVPOSS. TGA analysis revealed that the coating had good thermal stability, with 5% weight loss temperature up to 335 °C.

In this paper, a comparison of TiO2 thin films prepared by magnetron sputtering with a continuous and pulsed gas flow was presented. Structural, surface, optical, and mechanical properties of deposited titanium dioxide coatings were analyzed with the use of a wide range of measurement techniques. It was found that thin films deposited with a gas impulse had a nanocrystalline rutile structure instead of fibrous-like anatase obtained with a continuous gas flow. TiO2 thin films deposited with both techniques were transparent in the visible wavelength range, however, a much higher refractive index and packing density were observed for coatings deposited by the pulsed gas technique. The application of a gas impulse improved the hardness and scratch resistance of the prepared TiO2 thin films.

Cu-Ni-Si alloy with a different Co content was prepared by inductive melting and hot rolling. The alloy was solution treated at 950 °C for 1.5 h and aged at 450 °C, 500 °C, and 550 °C for different times. The phase diagram calculation and transmission electron microscopy was used to investigate the effect of Co addition on the aging precipitation behavior of the Cu-Ni-Si alloy. The phase transformation kinetics equation was calculated as well. The results show that, with the increase of aging temperature, the two-phase region of Fcc + Ni2Si in the Cu-Ni-Si ternary diagram would get wider. Some NixSiy phases would also form in the Cu-rich isothermal section. The addition of Co would replace part of Ni to form the (Ni, Co)2Si phase, which inhibits the spinodal decomposition process of the Cu-Ni-Si alloy during the aging process. The precipitated phase of the Cu-Ni-Si alloy with a high content of the Co element is more likely to grow with the extension of aging time. The phase transformation kinetic equations of the Cu-Ni-Si alloy at 450 °C and 500 °C showed good agreement with the experimental results. Furthermore, it can be seen from the precipitation kinetic curve the addition of the Co element accelerates precipitation in the aging process.
