Abstract
The way you move and sleep, interact with people around you, depression change everything. This even looks at the way you talk and express yourself in writing. Sometimes this “depression language” can have a strong effect to others. Natural Language Processing (NLP) is one of the fields of computer science, artificial intelligence, and language (linguistics) related to the interaction between computers and natural human languages, such as Indonesian or English. The main objective of the NLP study is to make a machine that is able to know and understand the meaning of language, lexical analysis has the role of reading input characters and generating output tokens and making spaces, tabs, newlines and connecting rows of programs. However, the problems will occur when lexical analyzers where lexical is not able to determine when there are misspellings on tokens. Therefore, with the development of the backward-forward pointer algorithm, it is expected that in the future it will be easier to analyze both the words in front, in the middle and behind, so that the machine can quickly determine the individual depression level of speech tokens and speech tones.

Abstract
Indonesia is an agrarian country and makes agriculture as one of the economic sectors, rubber, oranges and coffee farming plants are many cultivated commodities. One of the problems in the agricultural sector today is the prevention of pests and diseases. Cortikium salmonicolor fungus is one of the many diseases that harm farmers, corticum mushroom salmonicolor is a disease that causes the death of twigs, stems and roots of plants. By applying fuzzy methods, the design rules are made that can detect corticium salmonicolor fungi in plants, rubber, oranges and coffee, which have three inputs and one output. Each object was analyzed with the same treatment so that three indicators were found in determining the detection of the corticium salmonicolor fungus. Fuzzy logic is defined as a multilevel logic that provides intermediaries the value to be determined between conventional evaluations such as right or wrong, yes or no, high or low, and so on. As a result, this rule is used to detect salmonium corticium fungi. This research can be developed by creating expert systems and screening tools.

Published: December 2019

Abstract
In accessing or searching data by using Query or Join on applications that are connected to a database, the usefulness of the implementation of the data and the process time is important to note. There are many ways that a system management database can do in processing and generating answers to a query. All methods will eventually produce the same answer (output) but they would still have different values, such as the time to respond to data. Some queries that are often used for processing data are Hash Join and Nested Join, both queries have different algorithms but produce the same output. A client-based or network-based application was employed to test both algorithms or queries with running time parameters or the time to respond to data. The test was conducted by connecting the number of tables and the number of rows/records. The result of the study is that the query hash join’s speed in response to small amounts of data is better than the large data in the nested join.

Abstract
In companies both large and small, they must always communicate and exchange data to other divisions at a considerable distance. In carrying out the process of data exchange, it is not uncommon for the data to suffer damage and some do not even reach the destination, the incident is known as packet loss. Therefore, a routing protocol is needed to solve the problem. OSPF routing is the right routing to be implemented. Because, OSPF routing uses Dijkstra’s algorithm to find the closest distance, OSPF determines the best path based on the lowest cost and OSPF also divides its network into several levels, so the information dissemination on each router becomes that has been done, messages time from PC to PC get a range of values of 0.25%. Based on the analysis table of packet loss, the packet is categorized very well, because the packet sent is not much lost.

Abstract
Scale formation is a frequent problem encountered in industrial piping system. The occurrence of the scale is due to a chemical reaction between the dissolved ions in water. Calcium carbonate (CaCO3) is one of the scale that is often found. Scaling will thicken the pipe walls and can affect the rate off low or heat transfer. Hence preventing to the growth of scales is necesary in pipe. In this study some experiments were conducted on the growth of the scale of calcium carbonate in a test pipes, by reacting solution of CaCl2 and Na2CO each with a Ca2+ concentration of 3500 ppm with a flow rate of 30ml/min and temperatures used were 25°, 30° and 40°C. Malicbacid(C4H6O5) was added to the solutionas additive with concentrations of 0, 3, and 5 ppm. Calcium carbonate crystals could be seen from the results omorphological studies conducted using Scanning Electron Microscopy (SEM). The SEM results indicate that at 25°C and without additives, the scale comprises of calcite and vaterite, whereas with the additive of 5 ppm malic acid, the scale is vaterite with the larger crystal size and there is also calcite, but phase of the vaterite is dominant. At 40°C and without additive the crystal of a aragonite resembles a pile of needles.
