Published: June 2020

The development of increasingly sophisticated technology follows the needs of the community, one of them in the telecommunications world is FTTH (Fiber to the Home) which is an optical signal delivery format from the center of the provider to the homes of costumers by using optical fiber as a medium of delivery. Delivery by using this FTTH technology can save costs and provide better service to customers. The study was conducted by interview and observation methods with network objects and FTTH components belonging to Telkom Semarang and through the literature method by searching some literature. FTTH configuration starts with the ONT to rosette connected using a patchcord cable then from rosette to OTP using an indoor cable then from OTP to ODP outside the home is connected using a dropcore cable. ODP itself is the result of the distribution of distribution cables/ aerial cables leading to ODC. ODC to STO/FTM/ODF using feeder cable. FTTH network is very effective to use, because it can use triple play services (telephone, internet and IPTV) with just 1ONT/ modem at the customer s side.

Published: June 2020

According to energy observers from the Institute for Essential Services Reform (IESR) the number of electricity consumers in Indonesia has increased by an average of 6-7% annually followed by an increase in the area of its services. An increasingly broad network is directly proportional to the potential for interference with the transmission and distribution system. The 150 KV Rembang substations is part of the Java-Bali Interconnection electrical system in northern Central Java that supplies electricity to the Rembang and surrounding areas. Rembang 150 KV substation on May 24, 2019, RBG 01 feeder experienced a disturbance behind the RB1-32 recloser and it was recorded that in 2019 PMT it had been tripped 4 times. Besides, there has been a change in equipment in the form of transformer II. These problems indicate the potential for interference that is not anticipated by the protection system, namely Over Current Relay and recloser.  This study evaluates the setting of an outgoing 20 KV OCR protections and recloser on transformer II RBG 01 feeder Rembang 150 KV substation. The scenarios used are calculations with large variations of short-circuit current based on% distance, as well as the calculation of OCR and recloser settings with IEC 60255 standards. Setting currents in the protection equipment is regulated based on current conductivity (KHA) and load current on the recloser. The coordination of the protection settings resulting from this resetting will be compared to the conditions on the ground.  Existing (field) OCR outgoing feeder RBG 01 condition TMS OCR value = 0.228 seconds, Iset = 480 A, and t op = 0.3 seconds. The existing OCR recloser condition TMS OCR value = 0.120 seconds and Iset = 400 A. The results of OCR coordinating outgoing feeder RBG 01 obtained TMS OCR value = 0.135 seconds, Iset = 585 A, and t operation = 0.3 seconds. OCR recloser resetting conditions obtained TMS OCR value = 0.10 seconds, Iset = 240 A and t operation = 0.198 seconds. The resetting conditions have met the IEC 60255 standard because recloser working time is smaller than outgoing work time.
Mangrove leaves with outstanding content of free amino acids especially GABA, makes them candidates for functional food
Authors: Hinokidani K. , Koyama S. , Irie M. , Nakanishi Y.
Published: June 2020

Herbal remedies by using mangrove plants have been recognized in several countries, and
the plant materials are often consumed as a tea, which are infusions of dried plant parts
steeped in boiling water. These infusions from mangrove plants are believed to be
effective agents for treating and/or prevent infections, ailments, and diseases, and some
mangrove plants have attracted attention as functional food resources in recent years. To
reveal the beneficial properties of mangrove plants, clarification of the chemical
ingredient and its characteristics of mangrove plants is required. This study focused on
amino acids, which were functional ingredients (i.e., bioactive compounds) because amino
acids are expected to function as ‘functional ingredients’ in addition to conventional
‘nutrients’ in recent years. To demonstrate the further possibilities of mangrove tea, we
firstly evaluated the content of total amino acids in the leaf of several dominant mangrove
species with commercial teas as references. Next, we clarified the composition of amino
acids by using LC-MS analysis. As the results, free amino acid content (FAC) in leaf
sample of Rhizophora stylosa, Bruguira gymnorrhiza, Kandelia obovata, Avicennia
marina, Sonneratia alba, and Lumnitzera racemosa was 747, 1056, 946, 829, 623, and
896 mg/100 g DW, respectively. The FAC in all mangrove leaf samples were higher than
those in green tea of low price, black tea, oolong tea, barley tea, and mate tea. Moreover,
it was found that GABA accounts for over 10% of the total amino acid in the mangrove
leaf samples. Especially in mature leaves of K. obovata, the ratio was very high levels
35%. In the case of K. obovata, the contents were higher than GABA tea. Based on this,
we concluded that several mangrove plants, especially K. obovata has the potential of a
functional food which is GABA-rich.
Divergent population trends following the cessation of legal grizzly bear hunting in southwestern British Columbia, Canada

Published: June 2020

© 2019 Elsevier Ltd We conducted DNA capture-recapture monitoring of grizzly bears (Ursus arctos) from 5 to 17 years after hunting was stopped in two adjacent but genetically distinct populations in southwestern British Columbia, Canada. We used spatial capture-recapture and non-spatial Pradel robust design modelling to estimate population density, trends, and the demographic components of population change for each population. The larger population had 21.5 bears/1000 km 2 and was growing (λ Pradel = 1.02 ± 0.02 SE; λ secr = 1.01 ± 4.6 × 10 −5 SE) following the cessation of hunting. The adjacent smaller population had 6.3 bears/1000 km 2 and was likely declining (λ Pradel = 0.95 ± 0.03 SE; λ secr = 0.98 ± 0.02 SE). Estimates of apparent survival and apparent recruitment indicated that lower recruitment was the dominant factor limiting population growth in the smaller population. Factors limiting reproductive rates and population density could include poor habitat quality, particularly the abundance of high-energy foods, genetic Allee effects due to a long period of population isolation, or demographic effects affecting infanticide rates. The cessation of hunting was insufficient to promote population recovery for the low density, isolated population. Our research highlights the importance of considering mortality thresholds in addition to small population effects and habitat quality when recovering large carnivore populations.

Recommendations for Sickle Cell Disease: A Content Analysis of Websites
Authors: Andrews Druye A , Katherine Nelson , Brian Robinson
Published: June 2020

This paper reports on the findings of a study designed to establish website-based self-management recommendations for sickle cell disease. Google and Yahoo search engines were used to search the World-Wide-Web. Purposive sampling was utilized to select 28 websites that met the inclusion criteria. Data were manually collected from health education materials and subjected to qualitative content analysis. Self-management was conceptualized as actions involving preventive health, self-monitoring, self-diagnosing, and self-treatment. The results show that the websites recommend more self-management actions for preventive health and self-treatment than for self-monitoring and self-diagnosis. Frequent oral fluid intake, limitation of overactivity, eating a healthy diet, avoiding extreme temperatures, and infections were the commonest preventive health recommendations. Daily pain monitoring and general bodily inspections were the most frequent self-monitoring recommendations. Commonly cited self-diagnostic indicators were fever, persistent pain, enlarged spleen, and leg ulcers. The use of analgesics and non-pharmacological measures were regularly cited for self-treatment. Most recommendations were assessed as clinically safe as they align with standards for sickle cell management. Nurses and other professionals should teach patients how to assess the credibility of websites. This article is protected by copyright. All rights reserved.

Impact of Pushed Output on Students' Oral Production
Authors: López Kevin
Published: June 2020

With the advent of communicative methodologies, the promise to develop both fluency and accuracy was made as a goal for teaching and learning English as an international language. However, it did not happen (Richards, 2008). In an attempt to equalize students’ both semantic and syntactic competence, this study investigates the impact of Swain’s (1985) oral pushed output hypothesis on EFL intermediate students’ L2 oral production under a mixed method approach. The participants were 16 seventh grade EFL students from a private school in Ibagué, Colombia that were randomly assigned to an output and a non-output group. For five weeks, the output group underwent oral pushed output activities while the non-output group was merely exposed to comprehension activities. Quantitative and qualitative instruments to collect the data included pretest and posttest, audiorecordings, stimulated recalls, and interviews. Results revealed that although pushing students to produce meaningful oral output does not promote significant noticing of their linguistic problems in past narrative forms, students can modify more oral output through one-way pushed output activities than two-way activities and equalize their semantic and syntactic competence since they can engage in both processsings. Additionally, students perceived oral pushed output as an affectivity regulator in L2 oral production and as a trigger of exposure to L2 vocabulary, grammar, and pronunciation.
GENERAL TRENDS OF PROFESSIONAL TRAINING OF TEACHERS IN THE CONTEXT OF IMPLEMENTATION OF INTERDISCIPLINARY RELATIONS (FOREIGN EXPERIENCE)
Authors: Zaskaleta Svitlana , Shcherbakova Olena
Published: June 2020

The article deals with the question of applying the principles of cross-curricular approach in higher education in the countries of the West. The concept of interdisciplinary research is based on the premise that concepts and facts are not studied in isolation from each other. An analysis of the development of higher education in Europe and the US made it possible to highlight its general trend. It defines the application of cross-domain communication principles. Implementation of the cross-curricular approach is considered as a promising method for professional training of students for the application of knowledge in other disciplines. Common terms of this direction are defined. They are: cross-curricular approach, interdisciplinary approach, multidisciplinary approach, cross-disciplinary approach, transdisciplinary approach. A comparative characteristic of integration approaches is proposed. Cross-disciplinary analysis - studies a problem that is usually transformed into one discipline through the prism of another discipline (for example, learning a foreign language of professional communication is studied through profiling disciplines).
Multidisciplinary analysis - considers the problem from different points of view, without making a joint effort for the systematic integration of disciplinary views.
Inter-disciplinary analysis - considers the problem from different points of view, which leads to a systematic effort to integrate alternative views into a single or holistic framework of analysis The interrelationships between three different approaches are established. Given the differences, the three approaches have much in common. Thus, the level of discipline Multidisciplinary study based on themes. Interdisciplinary skills and concepts are embedded in the standards of the discipline. The transdisciplinary approach takes into account the real life context.
In the context of the cross-curricular approach, the integration of scientific literacy with the use of information literacy skills is considered. The purpose of information literacy is to improve both scientific and information literacy of students, the introduction of the concepts of scientific literacy in courses related to relevant topics. This model allows students to better understand scientific information and expand the scientific topics on which the research is conducted.

Special attention in the European educational space given to study foreign languages. In the context of an interdisciplinary approach, this means that semantic subjects are taught and studied in a language that is not the student’s native language.

TINJAUAN ASPEK TEKNIS PEMILIHAN MEDIA BIOFILTER UNTUK PENGOLAHAN AIR LIMBAH
Authors: Said Nusa Idaman , Marsidi Ruliasih
Published: June 2020

There are literally dozens of different types of biofilters used for wastewater treatment applications. While many have common features, some are fundamentally different from the rest. The purpose of this article is to educate the reader about the types of packings used for fixed film biofilters.The types of biofilters under discussion are filters that employ a non-moving surface area to provide a substrate for various bacteria to attach and grow. The substrate remains in place while the water flows through the system. The heart of these biofilters is the packing or media used to provide the surface area. The type of packing used strongly influences both the capital and operating costs of the biofilter. It is important to emphasize however, that the packing merely provides surface area for bacteria to colonize. It is the bacteria that do the actual work of the biofilter. In order for the bacteria to do their job effectively, the biofilter and packing design must provide an even distribution of nutrients and oxygen while removing dissolved and suspended waste products. Most biofilters utilize aerobic bacteria but it is also possible to design and operate anaerobic systems for special purposes. Various types of packings exist for fixed film biological filters. Each different type has advantages and disadvantages but in terms of overall cost and suitability, the structured packings are the best choice for commercial biofilter designs. Kata kunci : biofilter, media, pengolahan air limbah.

Water disinfection means the removal, deactivation or killing of pathogenic microorganisms. Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. When microorganisms are not removed from drinking water, drinking water usage will cause people to fall ill. Chemical inactivation of microbiological contamination in natural or untreated water is usually one of the final steps to reduce pathogenic microorganisms in drinking water. Combinations of water purification steps (oxidation, coagulation, settling, disinfection, and filtration) cause (drinking) water to be safe after production. As an extra measure many countries apply a second disinfection step at the end of the water purification process, in order to protect the water from microbiological contamination in the water distribution system. Usually one uses a different kind of disinfectant from the one earlier in the process, during this disinfection process. The secondary disinfection makes sure that bacteria will not multiply in the water during distribution. This paper describes several technique of disinfection process for drinking water treatment. Disinfection can be attained by means of physical or chemical disinfectants. The agents also remove organic contaminants from water, which serve as nutrients or shelters for microorganisms. Disinfectants should not only kill microorganisms. Disinfectants must also have a residual effect, which means that they remain active in the water after disinfection. For chemical disinfection of water the following disinfectants can be used such as Chlorine (Cl2),  Hypo chlorite (OCl-), Chloramines, Chlorine dioxide (ClO2), Ozone (O3), Hydrogen peroxide etch. For physical disinfection of water the following disinfectants can be used is Ultraviolet light (UV). Every technique has its specific advantages and and disadvantages its own application area sucs as environmentally friendly, disinfection byproducts, effectivity, investment, operational costs etc. Kata Kunci : Disinfeksi, bakteria, virus, air minum, khlor, hip khlorit, khloramine, khlor dioksida, ozon, UV.

These snis are used to compliment of testing from technology of hospital waste water treatment. There for, it is need to be more reinforce the application of SNI so that each the technical regulation don’t want to detail the technical aspect it self. This because to revise the legal regulation is not easy, meanwhile the SNI can be revised anytime we need. We need to continue and to increase cooperation (MOU) between the Ministry of Environment and the National Accreditation Committee (KAN), about the joint assessment accreditation of environment parameters quality laboratory. The good application of technology and standard will have a good impacts for the growth of economic environment equipments industry. From the hospital waste water samples in Jakarta has showed  that the chemical consentrate pollution very fluctuated, e.g.,  BOD 31,52 - 675,33 mg/l, ammoniac 10,79 - 158,73 mg/l, detergent (MBAS) 1,66 - 9,79 mg/l. From the BOD (mg/l) parameter with minimum 31, 52 and maximum 675,33 still include in the BOD parameter, as decree of KLH No 58/95, mentioned that the maximum gradient 75 mg/l, but to see from the mean as 353,43 are far out from the article of  KLH decree.  Key words : Air limbah, lumpur aktif, teknologi, SNI, lingkungan, standardisasi

Water is a very basic need for humans, especially for cooking and drinking. With the rapid growth of population in particular need of clean water for the community also increased in numbers. The problem is with the poor quality of raw water for drinking water, then in addition to expanding its production costs, the result is often less good. One of the problems or issues that are often found in drinking water in the world these days that is the emergence of compounds called Trihalomethanes or THMs abbreviated, as a side effect of the disinfection process with a chlorine gas or hypochlorite compounds.Currently, to removal organic pollutants, ammonia, detergents, odor and other micro pollutants in drinking water, PAM is usually used by the process of manufacturing processes using adsorbsi Powder Active Carbon Adsorption, continued with physicals processing is the process of coagulation, flocculation, sedimentation and disinfection with chlorine. With increasingly high prices of powdered activated carbon, coagulant and flocculant chemicals, then the cost of treating drinking water to be increasing. To solve the problem above, one alternative is to develop clean water treatment technologies using a combination of biofiltration and ultrafiltration process, and to produce drinking water to proceed with processing using the process of reverse osmosis. Within the combination of biofiltration, ultrafiltration and reverse osmosis processes to treat the river water can be produced the drinking water with a very good quality without the use of chemicals for coagulation-flocculation process, and operational costs are relatively low. Key words : Air siap minum, biofiltrasi, ultrafiltrasi, reverse osmosis

Groundwater is water that occurs naturally in the subsurface, and is contained in the aquifer. Groundwater is the water source of the most widely used by the public for purposes of clean water. To determine the condition of the aquifer configuration one of the methods that can be used is the 2D electrical resistivity. Exploration drilling is one effective way to determine directly the presence of groundwater, but to determine the location of the drilling necessary geophysical approach to describe subsurface conditions prior to drilling. 2D electrical resistivity method is a geophysical method that utilizes dynamic electrical properties of the media path. 2D electrical resistivity measurements have been carried out in Kapuas, Central Kalimantan using Wenner configuration, the distance between the electrodes 10 meters, penetration depth reaches 80 meters, and and measuring some 21 track. Water potential zones were identified based on having resistivity range 15-25 ohm.m, contained in the sandstone layer, which is covered in a layer of impermeable mudstone layers. Location that has a high potential for groundwater recommended drilling done on the track P-07 and P-13, with an estimated depth of the aquifer between 25 meters and 30 meters. The highest groundwater potential lies between the drilling data PH-23 and PH-24, with the resistivity at that point reaches 300 ohm.m. Keywords : Groundwater, aquifer, sandstone, 2D electrical resistivity, resistivity, Kapuas

Pengaruh Managerial Tenure Terhadap Tax Avoidance
Authors: Noviawan Andika , Dara Nida Utamie
Published: June 2020

Tujuan penelitian ini adalah untuk menganalisis hubungan antara managerial tenure terhadap tax avoidance. Penelitian ini dilakukan pada 65 perusahaan manufaktur di Bursa Efek Indonesia selama periode 2015-2017. Hasil penelitian menunjukkan managerial tenure tidak berpengaruh terhadap tax avoidance. CEO tidak melakukan tax avoidance guna mendongkrak reputasinya untuk memperpanjang masa kerja (tenure). Para CEO berupaya meningkatkan kinerja untuk memperoleh kepercayaan pemilik perusahaan, sehingga memperbesar peluang tetap menempati posisinya saat ini. Temuan lainnya adalah ROA tidak berpengaruh terhadap tax avoidance, tinggi rendahnya ROA yang dihasilkan perusahaan bukan merupakan pemicu tindakan tax avoidance. Selain itu, leverage tidak memiliki pengaruh terhadap tax avoidance. Sumber permodalan apapun yang digunakan perusahaan bukan merupakan upaya menghindari pajak. Perusahaan yang berusaha melakukan tax avoidance dapat melakukan berbagai skema selain thin capitalization, antara lain transfer pricing, treaty shoping, atau control foreign corporation. Implikasi penelitian ini tertuju pada strategi tax avoidance yang menarik sekaligus menguntungkan bagi perusahaan, namun di sisi lain dapat berakibat fatal dan merugikan.

Negotiations and teamwork are needed by anyone. A manager is expected to be able to suggest himself as an entrepreneur, the role of the problem solver, the role as the allocation of resources and the role of the final decision is the role of the negotiator. The role of the negotiator is necessary when dealing with outsiders in terms of determining cooperation or when the organization is confronted with conflicts of interest internally or otherwise. Negotiators must know examples, for example, when we are going to market the product. Follow-up from community service on extracting the potential of human resources to process the potential of human resources in terms of negotiating and team building can increase the added value of these human resources, which in turn can increase the income of employees, enthusiasm for work.
