Published: December 2018

The provision of clean water for all Indonesians is one of the objectives of the government that is still constrained by the limitations of the existing water supply infrastructure. Some areas, especially rural or remote areas, are still hard to reach by the clean water facilities of the Regional Water Company. Whereas the groundwater resources in this region are abundant but can't be explored optimally to meet the needs of clean water and proper consumption for the surrounding community. The availability of water is not balanced with its quality, especially as qualified water for consumption. Some other characteristics of rural areas such as poor sanitation and the presence of agricultural waste pollutants, result in groundwater quality being further away from the standard of consumption. Although there are some commercial water filtration technologies available, they are generally expensive, with limited capacity, and not intended for mass use. For that reason, a new breakthrough, by designing proper technology, which is not only affordable but also easy to use and have sufficient capacity to meet the needs of the community. This research used Quality Function Deployment followed by Functional Analysis Systems Technique to get the character of the user and design requirement of groundwater filtration technology which suitable with the community needs and water quality condition in rural areas. The result is a design of filtration technology consists of five main modules, namely filtration module, information module high voltage module, reactor module, and rack module. This design is expected to be the basis for developing clean water technologies for people in rural areas or others that are difficult to reach by the Regional Water Company infrastructure.
Feed Forward Neural Network Modeling for Rainfall Prediction
Authors: Hasbi Yasin , Budi Warsito , Rukun Santoso
Published: December 2018

Prediction of rainfall data by using Feed Forward Neural Network (FFNN) model is proposed. FFNN is a class of neural network which has three layers for processing. In time series prediction, including in case of rainfall data, the input layer is the past values of the same series up to certain lag and the output layer is the current value. Beside a few lagged times, the seasonal pattern also considered as an important aspect of choosing the potential input. The autocorrelation function and partial autocorrelation function patterns are used as aid of selecting the input. In the second layer called hidden layer, the logistic sigmoid is used as activation function because of the monotonic and differentiable. Processing is done by the weighted summing of the input variables and transfer process in the hidden layer. Backpropagation algorithm is applied in the training process. Some gradient based optimization methods are used to obtain the connection weights of FFNN model. The prediction is the output resulting of the process in the last layer. In each optimization method, the looping process is performed several times in order to get the most suitable result in various composition of separating data. The best one is chosen by the least mean square error (MSE) criteria. The least of in-sample and out-sample predictions from the repeating results been the base of choosing the best optimization method. In this study, the model is applied in the ten-daily rainfall data of ZOM 136 Cokrotulung Klaten. Simulation results give a consecution that the more complex architecture is not guarantee the better prediction.

This study assesses the gate-to-gate environmental impacts of food processing systems operating in Toba Samosir Regency using Life Cycle Assessment methodology. The systems in question are processing of tapioca, coffee, and tofu, with the functional units of 50 kg of tapioca starch, 1 kg of coffee powder, and 25 kg of tofu, respectively. The inventory data were collected directly from the producers in the form of both production records and interviews. The linked flows that describe the production process for each of the system are obtained as follow. In producing 50 kg of tapioca starch, 200 kg cassava root and 800 kg of water are required. This system generates 40 kg of cassava peel, 60 kg of pulp and discharges 850 kg of waste water. For starch drying 209 MJ of thermal energy is required in the form of heating fuel. In order to produce 1 kg of fine coffee, 4 kg of coffee cherry and 30 kg of water are required. This system generates 3 kg of cherry peel and pulp mixture as solid co-product and discharges 30 kg of waste water. For roasting and milling the coffee bean, 90 MJ of thermal energy is consumed from firewood and gasoline. In producing 25 kg of tofu, 11 kg of soybean, 0.2 kg of flour and 140 kg of water are required. This system generates 16 kg of wet pulp and discharges 89 kg of waste water. For milling, 250 MJ of thermal energy is consumed from gasoline and rice husk. Water is the most vulnerable environmental compartment since most of the waste water is being discharged into the stream with limited treatment. The environmental hotspots associated with these systems are eutrophication potential, global warming potential (climate change), acidification, and photochemical oxidation potential.

Based on Law 23 of 2014 on Regional Government, there is a change in the distribution of affairs in the management of education. Secondary education (SMA / SMK) previously administered by regency / municipality government based on the law is the authority of its management to switch to provincial government. This article will discuss how the process of execution of transfer of authority of secondary education from regency / municipality government to Central Java Provincial Government. Using qualitative research, this article will provide a critical analytical understanding of the transition process or the delegation of secondary education authorities in the areas of Asset, Human Resources (HR) and Finance from the Regency / City government to the Provincial Government in Central Java. The research findings show that the delegation of authority at the level of the Provincial Government actually makes the model of government farther away from idealism to provide services closer to the community. Because the implementation of this policy impact on local government policy, which has been eliminating education for 12 years, ie from elementary school to high school. As a result of the transfer of management function to the province, now the free education policy for SMA and SMK had to stop as well as happened in Kudus, Sukoharjo, Karanganyar. The community hopes the Central Java Provincial Government still holds a commitment to free education, both for public and private schools for high school / vocational high school level. In addition, there is hope from the community for the Provincial Government to implement a commitment not to withdraw fees, levies or donations after the transfer of education authority to the Central Java provincial government.

Eradicating Inequalities in Development by Impoverishment and Social Sanction for Tax Corruption
Authors: Abdul Rahman
Published: December 2018

Inequalities in development occur in almost developing countries worldwide including Indonesia. This condition is caused by powerlessness of government in fulfilling public interests because of the limitation of national budged as a result of corruption. Currently, corruption spreads to all government institutions including Directorate General of Taxes (DGT) as tax authority in Indonesia. Corruption in the area of DGT becomes an importance issue because it has a broad impact and destructive to economic development and it reduces the public trust toward this institusion. In Indonesia, tax corruption is built by some patterns that have similarities between the study result and testimony from tax corruption actors, in which there is the existence of tax mafia in protecting any corruption cases related to taxes. To eradicade this practice, this study suggests the impoverishment and social sanction as a strategy to provide deterrent effect, to minimize the corruption activities in tax sectors specifically and public sectors in general, to reduce the leakage of budget, and to increase the government income. By these efforts, it is expected the equalities in development to be achieved. To apply them, it is needed the seriousness and strong commitment from government.

Climate is an important element for human life, one of them is to agriculture sector. Global climate change leads to increased frequency and extreme climatic intensity such as storms, floods, and droughts. Rainfall is climate factor that causes the failure of harvest in Merauke. Therefore, rainfall forecast information is very useful in anticipating the occurrence of extreme events that can lead to crop failure. The purpose of this research is to model rainfall using autoregressive integrated moving average (ARIMA) model. The ARIMA model can be used to predict future events using a set of past data, including predicting rainfall. This research was conducted by collecting secondary data from Agency of Meteorology, Climatology, and Geophysics (BMKG) from 2005 until 2017, then the data was analyzed using R.3.4.2. software. The analysis result showed that ARIMA model (2.0,2) as the right model to predict rainfall in Merauke. The result of forecasting based on ARIMA model (2.0,2) for one period ahead is 179 mm of average rainfall, 46 mm of minimum rainfall, and 295 mm of maximum rainfall. Thus it can be concluded that the intensity of rainfall in Merauke has decreased and there was a seasonal shift from the previous period.

Failure of cement mantle of bond loosening between liner and cement mantle is an important issue in total hip replacement. Two factors that commonly cause cement mantle failure are initial crack and stress. A solution for reducing stress on the cement mantle has been proposed by adding insertion material between liner and cement mantle. Nevertheless, further study is needed to optimize the proposed solution. A possible option is to vary the thickness of the insertion material. If the thickness of the PMMA material is constant, then the variation of the insertion thickness will be followed by the variation of the thickness of the liner. Consequently, the stress value on the liner will follow the variation of liner thickness. The objective of this study is to examine the effect of the thickness variation of the insertion material to stress on cement mantle and liner using finite element simulation. Results revealed that the magnitude of stress and deflection decreased in the cement mantle and the liner along with the increasing thickness of the insertion material.

This study aimed to increase the range of the wireless IEEE 802.11 b/g by adding the antenna gain, testing the performance of access point with router access point mode of the wireless IEEE 802.11 b/g, and comparing the performance of access point with router access point mode of the wireless IEEE 802.11 b/g.This research was conducted in Makassar. The method used was by performing direct performance measurement of end to end node, namely: delay time, throughput and Packet Loss. Wireless access point was placed on the SPN tower (Sekolah Tinggi Kepolisian Negara/College of Police of State) of Batua. Wireless clients were placed at 2.7 km, 5.36 km, 8.81 km and 10.82 km.The results showed that wireless IEEE 802.11 b/g can be used for data communications up to 10.82 km by adding 24 dB of antenna gain. Wireless with access point mode and router access point mode experienced 100% of packet loss with 60000 bytes of window size packets’ delivery and can handle only 1000 bytes of window size packets. The performance of wireless with access point mode was better than wireless with access point router mode, as follows: For access point packet: 0% of lost wireless, 8 ms of delay time, and 1 Mbps of throughput; On the other hand, for router access point packet: 30% of lost wireless, 26 ms of delay time, and 0.31 Mbps of throughput.

The development of information and communication technologies (ICT) has changed many aspects of our lives around the world. ICT has played crucial roles in connecting people and places across regions and countries, also it helps global development more equally. It holds enormous promise for the future. In developed country like Indonesia the use of the digital advance to provide opportunities in economic and societal growth are vary, more chances in urban area than in remote area which is creating digital inequality. The young generations in Bengkulu province is having inequality of accessing and using the ICT, but the real problem is do they have the foundation to accept the ICT and does the social environment support for the changes? Case study method applied to understand the digital readiness of the young generations particularly the middle high school students and further to explore the social background as a way to minimizing the gap of digital inequality. Digital skills, trust, and use are the elements to measure the digital readiness. The result shows 1) the digital skills among the informants are still in basic level; 2) they depend on statement from friends and family in terms of trustworthiness; 3) they use the digital access mostly to chatting and watching YouTube. More affordable smartphone means more chance for the young generations to access the digital world but the social environment around them doesn’t support evenly.
