The growth of Gresik City is shown by the development of various infrastructures such as settlements, highways, and others. Along with the growth of Gresik City area, an increase in flood inundation due to increasingly dense settlements, decrease of vacant land as an infiltration area in Tebalo Village. Flooding is caused due to lack of development of drainage systems in the area of Tebalo Village. To normalize Tebalo drainage channel, good planning must be prepared for Tebalo drainage channel system including planning the layout of the channel system, calculating the designed flood discharge for each channel, hydraulics analysis for flood flow conditions and also along high sea water tide conditions, and finally designing the dimensions of the channel. After the channel is normalized, it is expected that the flow would be much smoother so that no flooding occurs.

Network Monitoring System (NMS) is a system that is highly demanded internet service provider industry in this fast-developing information technology era. The availability of NMS is the best option to restore the service level agreement as a means to compete with other internet service providersâ€™ competitors. The occurrence of disturbance in the network is often unnoticed by the network administrator. This may lead to a crucial problem in decreasing network quality as the impact of time-consuming in solving the problem. Through the explanation, the writer tried to anticipate by classifying problems using Pareto and integrated Nagios with Telegram Messenger as a notification of disturbance. Nagios has many features such as reports, event handlers, monitoring resources (CPU load, memory usage, status up / down, uptime, data traffic, bandwidth), etc. One notable feature owned by Nagios is blast notification of disturbance. It is a feature that will function when one of the devices is in trouble. This feature will inform the network administrator or authorized person in certain divisions as regards the error network. In this case, the problematic device can be categorized according to the parameters made by the network administrator.

Concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate, and water, with or without additives (admixture). The naphthalene superplasticizer used comes from the distillation of coal tar and a little from the rest of petroleum, but there is also camphor naphthalene. Where camphor grains contain 250-500 mg of naphthalene. Naphthalene is mostly produced from coal tar distillation, and a little from the rest of the fractionation of petroleum, by the molecular formula (C10H8) and in the form of two unified benzene rings. This compound is volatile, volatile even in the form of solids. The vapor produced is flammable. The purpose of this study was to determine the effect of the use of naphthalene from coal tar waste with camphor naphthalene as concrete admixture, and determine the effect of naphthalene from coal tar waste with camphor naphthalene on concrete toughness, density, water absorption, of concrete compressive strength. It is expected that the use of naphthalene can reduce the use of cement, and reduce water use. But it does not reduce the strength of the concrete so as to reduce costs in making concrete. The variations in the use of camphor naphthalene and coal tar naphthalene are 20%, 30%, 40%.

Generally, Drainage could be defined as technical measures to reduce excessive water, either from rainwater, permeation, or excessive irrigation water from a region, therefore the land function not disrupted. The purpose of this study are to analyze, learn and evaluate the drain condition and capacity in the Bukit Cengkeh II Residential, Cimanggis Sub-district, Depok City specifically in blockhouse G, H and I to the flood discharge that occurred. The data and information used for this study are primary data (personal research data collected by the author) and secondary data (rainfall from BMKG and nearest Irrigation Center). Flood discharge study methods use two methods, i.e. Rational method and Hasper's method. From these two methods, we used the largest volume of the flood discharge. The results of the Flood discharge planning in block G are 2,39 m3/sec, block H are 5,42 m3/sec, and block I 1,12 m3/sec. There found 10 drains identified as runoff or unsecured. The alternative solutions to runoff or unsecured drains problems are create a new drains dimension plan or construct an infiltration well.

Cost planning is an important phase on construction project planning to give illustration to the owner how much cost they should spend to execute that project. The slab is an element of the structure that has a large amount of the quantity so that affects the cost of the whole project. Then the cost comparison of slab structure has to be analyzed to know the most optimum design between conventional shuttering with the concrete beam on the initial design, first alternative options design, and metal deck shuttering with steel beam on second alternative design. The calculation of the slab structure cost analysis were based on Indonesiaâ€™s standard (PermenPUPR and SNI). The result is the first alternative options design that using concrete beam were cheaper 10,24% than the initial design that using concrete beam too while the second alternative options design that using steel beam were more expensive 27,14% than the initial design.

It has been known that most the college students face problems in communicating in English, especially in non-English-speaking country. The main cause is the teacher failed in choosing the appropriate approach for students. Further, it is necessary to choose a proper approach for college students for teaching speaking skills. From a philosophical point of view, there are two sorts of teaching approaches. These are the andragogy and pedagogy approaches. Andragogy is used for adult learners, and pedagogy is used for young learners. Seen from their age, students at colleges are positively categorized into adult students. Therefore, this paper aims to investigate the implementation of andragogical approach for teaching speaking skills in the intensive English program of Maulana Malik Ibrahim State Islamic University of Malang. This is qualitative descriptive research that the data collection method is an interview. The result revealed that most the teachers in intensive English program in Maulana Malik Ibrahim State Islamic University of Malang have been applied andragogical approach for teaching speaking skill. Hence, the researcher concludes that andragogical approach is the appropriate approach for the adult learner, especially in teaching speaking skills.

Publisher : Yayasan Ahmar Cendekia Indonesia

Nepal is rich in biodiversity in terms of both flora and fauna. While significant effort has been given to the conservation of wild animals, rare or otherwise, same cannot be said for the floral diversity of the country. In fact, due to significant challenges, the floral diversity of the country remains largely unexplored. The system proposed in this paper tries to overcome those challenges by using technology to aid the collection of information about the floral diversity of the country by crowdsourcing at a local level, using the image data collected for the plant identification by using machine learning or through expert users/volunteers.

In this paper Amplified Water Cycle Algorithm (AWCA) has been used to solve the optimal reactive power problem. Water cycle algorithm (WCA) is a methodology which inspired by the hydrological cycle which happen in nature. In this work water cycle algorithm hybridized with Gravitational Search Algorithm, Chaos theory. In the projected Amplified Water Cycle Algorithm (AWCA) - with reference to the fitness value, population is first alienated into three groups: streams, rivers and sea. Through this hybridization exploration and exploitation is effectively improved. Positions of particles are initially modernized according to gravitational search. Chaos theory is then defined and integrated in water cycle algorithm to modernize the population which will augment explore capability and population diversity. Projected Amplified Water Cycle Algorithm (AWCA) has been tested in standard IEEE 14, 30, 57, 300 bus test system and simulation results show the projected algorithm reduced the real power loss extensively.

Publisher : Yayasan Ahmar Cendekia Indonesia

Mutual funds are one of the promising investment media where the risk is directly proportional to the size of investment growth. With proper forecasting of NAV price movements will greatly help investors to make purchases and sales transactions, therefore the authors offer the use of two different forecasting methods namely Brown's method and Holt method in double exponential smoothing to get predictions of NAV price movements. The effectiveness of the use of the method will be measured from the value of Mean Average Percentage Error (MAPE). From the calculation results obtained by the data that the Holt method produces forecasting for 1809,657 with the best Î± value of 0.6 and MAPE of 0.644373568, while for the Holt method obtained forecasting value of 1810,924 with the Î± value and the best Î² value of 0.9 and 0.1 and the smaller MAPE value of 0.61604262 . Looking at the amount of MAPE generated, the Holt method has a smaller forecasting error rate when compared to Brownâ€™s method.
