Authors: Wardhana Krisna Adhitya , Effendi Agus Jatnika 
Published: June 2020

Membraneless-Microbial Fuel Cell (ML-MFC) satu kompartemen dengan katoda kontak udara saat ini sedang dikembangkan dan menjadi alternatif solusi untuk sumber energi terbarukan yang mampu menghasilkan listrik dari proses degradasi substrat. MFC membutuhkan substrat yang kaya senyawa organik seperti air limbah dari proses pencucian pulp. Pada air limbah ini terdapat lindi hitam dalam kondisi terencerkan yang mengandung lignin dan kaya senyawa organik sehingga memiliki potensi untuk digunakan sebagai substrat dalam reaktor MFC. Selain itu, penggunaan substrat berupa air limbah industri memiliki efek yang baik terhadap lingkungan karena berkontribusi dalam pengurangan kontaminan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi awal Chemical Oxygen Demand (COD) air limbah pencucian pulp sebagai substrat terhadap arus dan voltase listrik yang terjadi dalam MFC. Dalam penelitian ini, reaktor MFC mengolah air limbah pencucian secara batch dengan 4 variasi konsentrasi COD yaitu 613 mg/L, 833 mg/L, 940 mg/L, dan 1620 mg/L dengan pH 8,91 - 10,03. Hasil penelitian menunjukkan MFC mampu mereduksi COD air limbah pencucian pulp sebesar 34 - 48%. Terkait potensi listrik, akumulasi arus listrik yang terjadi pada MFC sebesar 12,67- 39,17 mA/m2 pada kisaran voltase tertinggi dari 4 reaktor sebesar 214 - 287 mV. The Concentration Variation of Wastewater From Pulp Washing Process in Membraneless Air Cathode Microbial Fuel CellA one compartment Membraneless-Microbial Fuel Cell (ML-MFC) with an air cathode was recently developed and became alternative solution for renewable energy sources to generate electricity from substrate degradation. MFC needs proper substrate that was rich in organic content such as wastewater from pulp washing process. The wastewater contains black liquor that was already diluted and contains lignin and high organic content, so that it would be potential as MFC substrate. Furthermore, the utilization of industrial wastewater as substrate can contribute positive effect to the environment namely contaminant reduction. This research was conducted to understand the effect of initial Chemical Oxygen Demand (COD) concentration of wastewater from pulp washing process to electricity current and voltage occured from MFC. The wastewater from pulp washing process with 4 initial COD concentrations (61, 833, 940, and 1620 mg/L) and pH ranged from 8,91 to 10,03 were batch treated in a batch system using the MFC. The results showed that 34-48% COD removal can be performed by MFC. Related with electricity potency from MFC, electricity accumulation current happened on 12,67 mA/m2 - 39,17 mA/m2 at highest voltage from 4 reactors of 214-287 mV.

Published: June 2020

There have been plenty of studies on translation accuracy, but that focusing on cultural words under-investigated. The current study investigated the translation accuracy of The Maze Runner Novel in English by James Dashner into Indonesian by Yunita Candra. As many as 11 cultural words were collected. To measure the accuracy, questionnaires were distributed to 12 translators of at least 1 year of professional experience. The taxonomy developed by Pelawi (2014) covering categories of accurate (<strong>Ak</strong>), less accurate (<strong>KAk</strong>), and not accurate (<strong>TAk</strong>) was applied. Results show that (Ak) occurs 7/64%, (KAk) does 3/27%, and (TAk) does 1/9%. That a number of the data fall into the category of (KAk) and (TAk) indicate that while cultures share common features (universal), at the same time they contain characteristic features that are unique. It goes, therefore, no cultural expressions can be in total accuracy if they are transplanted into other cultures.

Published: June 2020

Objetiva-se discutir a problemática das condições de riscos e vulnerabilidades socioambientais nos cenários do Semiárido paraibano e Médio Vale do Itajaí (SC), respectivamente, no Nordeste e Sul do Brasil. Parte-se do pressuposto de que o alcance dos dois problemas emblemáticos de (i) escassez e (ii) excesso de água apresentam riscos sociais e ambientais. Com base em um argumento socioambiental é relevante compreender que a questão da escassez de água no Semiárido nordestino se debruça sobre as questões de acesso e distribuição da água, ocasionando conflitos socioambientais. Enquanto a questão do excesso de água no Vale do Itajaí apresenta um indicador significativo de vulnerabilidade resultante das cheias, deslizamentos e enxurradas na localidade. A metodologia da pesquisa se caracteriza por um diagnóstico descritivo explicativo de caráter exploratório. Os principais resultados apontam para argumentos os quais enfatizam que com o crescente aumento da população urbana em todo o mundo é premente incorporar o conhecimento dos riscos e vulnerabilidades a que esta população está sujeita, e o planejamento para a gestão e gerenciamento da água. Medidas de mitigação e adaptação a estes riscos que aumentem a resiliência socioecológica são evidentemente necessárias e precisam ser incluídas no planejamento e na gestão das cidades. Estas medidas necessitam reforçar a legitimidade nos processos de governança por meio da participação social. A B S T R A C TThe main purpose of the paper is discuss the risk conditions and social environmental vulnerabilities in the scenarios of the Médio Vale do Itajaí (SC) and Semi-Arid Paraiban, respectively, in the South and Northeast of Brazil. It is assumed that the scope of the two problems of (i) excess and (ii) water scarcity pose social and environmental risks. Based on a socio-environmental argument it is relevant to understand that the issue of water excess in the Vale do Itajaí presents a significant indicator of social vulnerability resulting from flooding, landslides and floods, the issue of water scarcity in the Northeastern Semi-Arid focuses on the lack of water access and distribution, causing social and environmental conflicts in the communities. The research methodology is characterized by an exploratory descriptive diagnosis. The main results point out arguments that emphasize that because of the growing urban population worldwide it is urgent to incorporate the knowledge of risks and vulnerabilities to this population, and its correct management. Mitigation and adaptation measures to these risks that increase socio-ecological resilience are obviously necessary and need to be included in city planning and management. These measures need to strengthen legitimacy in governance processes through social participation.Keywords: water management, social and environmental vulnerability, resilience, Paraíba, Vale do Itajaí.
THE HUMAN HAIR FOLLICLE PULSATING BIOMAGNETIC FIELD REACH AS POSSIBLE ADDITIONAL FACTOR IN MIGRAINE HEADACHES A BIOPHYSICS BASED HYPOTHESIS
Authors: Embi Abraham A. 
Published: June 2020

This manuscript introduces a hypothesis linking the intrinsic pulsating nature of the biomagnetic fields reach found in the human hair follicle as factor in the etiology of migraine headaches. In the last two decades, researchers have emphasized the efficiency of external pulsed electromagnetic fields in the treatment of migraine headaches.
Clinical trials have also demonstrated that external pulsed electromagnetic fields may prevent or decrease the migraine attacks. A hypothesis is presented linking the inherent hair follicle pulsed bioelectomagnetism as a factor in the etiology of migraines. Does the internal pulsed biomagnetic field reach of the hair follicles factor in the genesis of migraine headaches? Supporting the hypothesis are published papers confirming the inherent biomagnetism of the human hair follicle. The introduction of a novel optical microscopy technique using a special Prussian Blue Stain (PBS) mixed with fine iron particles has produced numerous papers confirming the inherent biomagnetism of the human hair. This manuscript expands on those findings by introducing documentation of the hair follicle pulsating biomagnetic field reach. This is demonstrated by using diamagnetic as well as paramagnetic preparations mixed with iron particles. Still microphotographs and video-recordings are presented.
