Abstract
At present, Knowledge Management (KM) is considered an appropriate competitive tool for success in a knowledge-based economy, many organizations have deployed and implemented KM to improve performance. The purpose of this paper is to provide guidelines and assessments for organizations to evaluate the level of KM maturity in national construction service companies in Indonesia and ways to increase them in order to improve organizational performance. The first step in achieving the objectives of KM is the current status of recognition of the ability of KM itself in the company obtained through the knowledge management maturity model. What is the level of KM maturity in the world of national private construction in Indonesia? If it is still low, how to improve it so that the companys performance is better. To increase the level of KM maturity, a review of harmony with key success factors or critical success factors (CSF) is needed to improve organizational performance. Seven functional criteria are used as key elements towards an effective KM approach, namely policies / strategies, HR planning and processes, training and improvement of human performance, procedure methods & documentation processes, technical solutions (IT), approaches to capturing / using tacid knowledge, and KM culture.

Abstract
Simply put, fintech is the answer to advances in information technology related to financial affairs. In the past, people who want to get financing services must always be in contact with banks that require special time. Now, not anymore. Simply by playing a finger on the gadget, one can get the same service in online transactions. In this journal Want to discuss more about what is fintech, understanding, and its benefits? Financial technology, often abbreviated as fintech, is technology and innovation that aims to compete with traditional financial methods in the delivery of financial services. Many industries have developed using technology to enhance financial activities. The use of smartphones for mobile banking, investment services in various currencies is one example of technology that aims to make financial services more accessible to the general public. Companies that have used financial technology consist of startup companies and financial institutions as well as ordinary companies that are trying to replace or increase the use of financial services provided by existing financial companies. Looking at a more macro level, global investment in financial technology increased by more than 2,200% from $ 930 million in 2008 to more than $ 22 billion in 2015. The nascent financial technology industry in London has experienced rapid growth over the past few years, according to London Mayors office 40% of the City of Londons workforce is employed in financial and technology services. In Europe, $ 1.5 billion was invested in financial technology companies in 2014, with London-based companies receiving $ 539 million, Amsterdam-based companies $ 306 million, and Stockholm-based companies receiving $ 266 million in investments. After London, Stockholm is the second highest-funded city in Europe in the past 10 years. The European fintech deal reached a five-quarter high, up from 37 in the 4th quarter of 2015 to 47 in the 1st quarter of 2016. Lithuania began to become the center of northern Europe for financial technology companies since news in 2016 about the possibility of Britains exit from the European Union. Lithuania has issued 51 fintech licenses since 2016, 32 of them in 2017. It illustrates that the urgency of applying financial technology is fundamental and can have a very positive impact on the conditions of individuals, institutions or companies and even creates regularity and ease of access finance on a national and international scale.

Abstract. Diversification of food processing based on Local Resources continues to be sustainable. Sweet potato is one of the local food commodities with quite high productivity but its utilization is still limited. Noodles can be said to be the 2nd staple food after rice. Noodles are generally made from flour. Purple sweet potato is very potential to be used as a substitute material in making noodles, because the carbohydrate, fiber, and antioxidant content are quite high. The purpose of this research was to develop wet noodle products with substitute purple sweet potato flour with a concentration of 20%, 30% and 40% and purple sweet potato puree with concentrations of 40%, 50%, and 60%. The method used in this research is experimental research complete random design 2 repetitions. The results showed that the best formulation of purple sweet potato flour substitution was 20% concentration with preference level more than 62%. The best formulation of puree purple sweet potato substitution was 50% concentration with product preference level more than 82%. So it can be concluded that the fresh noodles with puree of purple sweet potato substitution were more acceptable than substitution with flour of purple sweet potato.

Abstract
Increasing human activity leads to increased concentrations of greenhouse gases in the atmosphere, especially carbon dioxide (CO2) and methane (CH4) that impact climate change and global warming. This condition encourages the occurrence of weather anomaly phenomena in the atmosphere such as rainfall fluctuations, dryness, increase in air temperature and sea-level rise. Sea-level rise was a potency of seawater inundation that gave an impact on land degradation. The study aimed to determine sea-level rise used three variables of disaster with two cumulative scenarios. The toward step used the simulation using a raster calculator in ArcGIS 10.2 to analyze the impact of sea-level rise to inundation disaster. The results showed that the sea-level rise on the South Coast of Yogyakarta based on (1) Scenario 1A (existing) were 1.4457 m (the prediction year 2030) and 2.0827 m (the prediction year 2050). According to the scenario (2) 1B (extreme) is 1.6297 m (the prediction year 2030) and 2.2667 m (the prediction year 2050). The increase in the sea-level rise on the south coast of Yogyakarta provides a disaster effect of inundation in the area directly dealing the beach and near the river mouth for example in Bantul Regency and Kulon Progo Regency.

Abstract
Abstract Groundsill is a structure in the form of a weir that is built across the river which aims to reduce the speed of the current and increase the depositional discharge in the downstream part of the bridge pole structure. Supercritical flow and sand mining at downstream of the bridge can endanger the pillar. Scouring around the bridge pillars can endanger the girder which of course endangers the bridge as a whole. The aims of this study were to analyze the stability of the Groundsill Bridge in the Garang River channel on the force of rolling, sliding, eccentricity, carrying capacity of the soil, and piping. This research uses survey method. Data collection methods used were observation and secondary data. Analysis of the data used were (1) rainfall design of 50 years return period; (2) design flood discharge with a 50 year return period; (3) the forces acting on the groundsill, and (3) the groundsill stability. The results of the study indicate that: (1) the groundsill were safe against rolling forces under normal flow and flood flow conditions; (2) groundsill was safe against shear forces under normal flow and unsafe during flood flow conditions; (3) groundsill was safe against eccentricity in normal flow conditions and unsafe in flood flow conditions; (4) the carrying capacity of the groundsill subgrade were safe against forces that occur during normal conditions and unsafe during flood conditions; and (5) groundsill was safe against piping under normal flow and flood flow conditions. The recommendation that can be submitted was the groundsill of the bridge in the Garang River channel should be equipped with energy dissipation, besides that the dimensions of the groundsill body are enlarged.

Abstract
Employee attrition can become a serious issue because of the impacts on organization-s competitive advantage. It can become costly for organization. The cost of employee attrition would be the cost related to human resources life cycle, lost knowledge, employee morale, and organizational culture. The aim of this study was to analyze employee attrition using logistic regression. The result obtained can be used by the management to understand what changes they should make to their workplace, in order to get most of their employee to stay. The data for study were around four thousand employees covering a period of 261 days (one year working days), during 2015. The data were organized between January and December. R was used for data integration, exploratory data analysis, data preparation, logistic regression, model evaluation, and visualization. The study was divided into five steps: (1) data collection and business understanding, (2) data pre-processing, (3) exploratory data analysis, (4) model selection and training, and (5) test and evaluation of the model. The result of the study found eleven variables as key driving factors for employee attrition. It also showed that the model has 75 percent accuracy with 73 percent sensitivity and 75 percent specificity.

Abstract
In open mining systems, the most important problem in mining production activities is surface water management, where surface water management is an integrated water management activity with the aim of minimizing the negative influence of surface water which consists of mine drainage methods, mine drainage, sediment separation and control. Geographic Information Systems (GIS) can be used for hydrological analysis using spatial data, especially in calculating runoff discharges from surface water. The method used in calculating runoff discharge is in the form of daily rainfall data. This rainfall data can show the influence of the catchment area which is useful for knowing precisely and accurately the runoff water discharge. Geographic Information Systems (GIS) are used to calculate variables in rational formula equations by overlay analysis. Information about digital-based hydrological conditions is very useful as a means of decision making and policies undertaken in monitoring hydrological conditions in open mines. By using a geographic information system (GIS) with a geodatabase attribute, it can be used to view general conditions in a mining area in monitoring hydrological conditions. So it is very appropriate to be used as hydrological monitoring in the mining area in making decisions that are fast, precise and accurate. Apart from that the geodatabase attribute can see the actual conditions of a mining area.

Abstract
The writing of this paper aims to determine the Hypertext Preprocessor (PHP) framework that is widely used and analyze the benefits of the framework in making a web application. A systematic review through a review of articles about the PHP framework. Article search is accessed from an internet database search. Articles taken from 2014-2019. The PHP framework can simplify the process of developing web applications because the concept has already been determined. Whereas if you use regular PHP, a programmer makes coding, folder structure or configuration is made as he wishes. Usually, the PHP framework uses the concept of Model-View-Controller (MVC), its function model is for database queries, its View function is for displaying HTML (Hypertext Markup Language), the controller functions for calculations or logic. The result is that PHP Laravel and CodeIgniter frameworks are the most widely used in building a web application. The PHP framework makes web application development faster and more stable. The selection of the right PHP framework for the project making a web application can also affect the performance results obtained after the web application is completed.

Abstract
This article aims to provide an overview of: 1) the ability of lecturers to understand the functions of ICT in learning practices; 2) the ability of lecturers to use ICT in learning practices; 3) the ability of lecturers to manage ICT-based learning practices; and 4) the ability of lecturers to conduct ICT-based learning assessments. The study was conducted at IAIN Kendari using a qualitative approach. Data collection is done through observation, interviews, and study of learning documents. The research findings show that the lecturers understanding of the function of ICT in the learning process is still low, so that it also results in a low ability of lecturers in ICT-based learning. Another result is the low ability to manage ICT-based learning, including weaknesses in conducting ICT-based assessment. Because of that, a technology literacy improvement program is needed for lecturers in Islamic Higher Educaton.

Abstract
This paper describes the research results to identify the characteristics of objects using image processing with the method of flat area geometric measurement, color measurements, size measurement, shape characteristics, and texture characteristics as data information used to decide on two groups of objects using the method of the Linear Discriminant Analysis for the application of mangosteen grading and sorting process. The proposed solution method is the use of four image sensors placed at four different monitoring angles. Each image sensor provides a decision on the group of objects it identifies, "accepted" if it meets all the objects requirements or "rejected" if one of the objects characteristics requirements is not met. The results of each image sensors decision are sent to the sink node in the wireless sensor network environment to be decided together using the sensor fusion method whether the objects identified in the group are "accepted" by all image sensors or "rejected" by one or more sensors image. The grouping results give a 10% error rate, and the biggest identification error comes from the color measurement.

Abstract
Sedimentation at coastal city of Cirebon is caused by considerable abration process in Indramayu regency and the impact of sand mining on Gosong Island, Indramayu Regency, beside that, the habit of residents in coastal city of Cirebon who heap up garbage at the coastal for years to utilize the area for residential purpose also contributed significantly the problem of sedimentation in the coastal area of Cirebon City. This research applying remote sensing technology of Landsat 7 2005, 2007, 2010, and 2015 using Lemigas Algorithm to gain information of special and temporal increase of sedimentation, distribution pattern, and density level of sedimentation. The result shows that accretion of sedimentation process between 2005 and 2015 at Lemahwungkuk Subdistrict is 56,989 Ha with a sedimentation rate of 5,699 Ha/year. Kejaksan Subdistrict has increase sedimentation by 16,491 Ha with a sedimentation rate of 1,649 Ha/year. The most significant increase happened at 2010 to 2015, with 46,072 Ha. However, from 2005 to 2010 the sedimentation increased by 5,675 Ha. There are 2 types of distribution pattern at Cirebon City, the first one is the sedimentation that ends in the estuary of river, particularly at Sukalila and Kesunean River deltas. The other type is the sedimentation caused by the presence of longshore currents which carry sediment and stuck on the coast along coastal city of Cirebon. Identification of natural and artificial sedimentation is carried out based on surveys in the field. The Lemigas Algorithm used only for classification of sedimentation (natural and artificial) based on density level of sedimentation content (mg/L).

Abstract
Bandung have about 2 million people that stayed in that 8.572 hectare urban area that have population density a 149 people / hectare in year 2017. The city of Bandung only has an area of about 502 hectare of urban parks, which is not enough to serves all the citizen to get access to that park. The study is analysing level of accessibility of the citizen to reach the park services, in term of how far and wide the city park can serve the surrounding community. This Research using one of the Network Analysis in Geographic Information System (GIS) method, which is Service Area, with assumption that one park can be reached by walking by citizen in radius of 1 km around their house. The result show that the existing of the park in Bandung City can only serve about 5.516 Ha of urban area, that means it only serve 2/3 urban area in Bandung City. In the diverse of urban park in Bandung City, its distribution has not been distributed well, in east and south of Bandung City there is a blank spot that the citizen cannot reach the city park. With this research, it can be one of input to the local government when they want to build the new city park they can build in the east and south area of Bandung City

Abstract
Cilember river flows from North to South of Cimahi and crosses PURBALEUNYI Toll Road in downstream. Therefore normalization of Cilember river Cimahi can impact the PURBALEUNYI Toll road. Hydraulic simulation carried out to determine the impact and formulate the mitigations alternatives. The study was conducted based on Detail Engineering Design Data for Cilember Normalisation Program prepared by Citarum River Authority as a base data. Two-dimensional HEC-RAS model was used to simulate the impact of the river normalization program. The model also used to evaluate the alternatives (detention pond, diversion of flows) to minimize the impact of the Cilember normalization program to PURBALEUNYI Toll road. Applying 10 year return period and HEC-RAS simulation, with an existing condition, 26 505 sqm area is inundated mostly in the North area of Toll Roads. After the normalization program, the inundation area shifts to the south area, including Toll road. The further simulation shows that normalization of the river can reduce inundation area to 7 993 sqm. Simulation of combination between detention pond and diverting the excess flow of Cilember to Kali Malang inundated area occurs, but it does not affect the toll road.
