One interesting thing is the relationship between personality differences and the types of words that people use. Recent studies covers an observing the relationship between personal qualities and the use of language in creating self-description. Text files are organized for transcription LIWC analysis to calculate the percentage of clout, authentic, and drives that student’s use. The results supported this possibility: LIWC’s clout, authentic, and drives dictionaries can be used as indicators of the student’s prevailing, confidence, motives and needs, we found that when calculated on written text, LIWC scores were connected with language dimension and psychology issues. These findings recommend that LIWC clout, authentic, motives, and needs dictionaries possibly will catch self-reported subjective emotion experience when applied to everyday activities. To enrich students’ confidence, power, motives, and needs toward the psychology issues faced by the students, students should be stimulated to discover the field of psychological processes and linguistic patterns by detecting their emotional and perceptual experiences.

Green Ladybug Nezara viridula L. spread in tropical and subtropical regions such as in America, Africa, Asia, Australia, and Europe. Imago N. viridula or nymphs attack the legume plants in the generative phase by piercing and sucking pods. So far, farmers are still using control technology in the form of chemical insecticide applications. Chemical insecticides are only able to kill the nymph and imago stages. Meanwhile, the egg stage is still able to survive and continue to grow because there are still a few chemical insecticide compounds that can thwart the hatching of eggs. Entomopathogenic fungi are one of the potential biological control agents for controlling N. viridula eggs. Because entomopathogenic fungi can infect all insect stages of eggs, nymphs or larvae as well as imago. This research was conducted using a Completely Randomized Design (CRD), with three replications and nine treatments (control, B. bassiana, M. anisopliae, and fungi isolates of Metarhizium sp., such as MetTmM, MetTrM, MetKM, MetKpP, MetKP, MetTrP). The results showed that the lowest percentage of eggs hatched due to MetTrP isolate reached 0%, but not significantly different from B. bassiana (10%) and MetKP isolate (11.67%). The highest percentage of hatched eggs was caused by MetTmM isolate which was 63.33% with the same conidia density which was 108 conidia/ml. All fungi isolate tested could infect N. viridula eggs.
Numerical Study on Behaviour of Spiral Concrete Columns and Slender Concrete Filled Steel Tube (CFST) Columns against Concentric Axial Loads
Authors: Wijaya Usman , Sanjaya William

Concrete columns with a circular cross-section have been used since a long time ago due to its better performance and advantages in many ways. The value of axial force in circular column is greater than in square column under the equivalent condition. To date, there has been no study that compares CFST behaviour with spiral concrete columns. This study can fill the gaps in comparative studies in between performance of the two types of columns with axial loading on slenderness variations using finite element modelling. Based on the results of the finite element modelling, with the same material capacity the CFST column has a greater resistance to geometric or bending failure with 8.63% than the spiral concrete column. The CFST column has a larger Critical Buckling Load than the spiral. And in general, with the greater the value of L/D or the slenderer the column is designed, the value of the Critical Buckling Load will tend to decrease and this occurs in both types of columns.
Evaluation of Total Armada Transport City Route 05B in Cianjur City
Authors: Setiawan Devi
Published: February 2021

The transportation problem is a classic problem that occurs in almost every city in Indonesia, including the city of Cianjur which is located in the province of West Java. One focus of transportation problems in the city of Cianjur is about the number of Cianjur city transportation that is too much operating but not balanced with the number of passengers served. This condition causes the city transportation drivers to fight over passengers to catch up with deposits. The method of conducting the research was carried out by a dynamic survey, carried out in a vehicle by the method of recording the number of passengers who boarded and alighted vehicles traveling on a route, where the officer recorded the number of passengers who boarded and descended and or travel time in each segment. After analyzing, the loading factor value for rush hour and rush hour turns out to be under 50%. The average number of fleets 05B needed to be based on circulation time (K) at morning rush hour 1 unit vehicle/hour, rush hour afternoon 2 units vehicles/hour, and during the afternoon no rush hour 1 unit of vehicle/hour. While the number of trips (fleet trips) needed in the busy period and non-busy time (K ’) in the morning rush hour 2 vehicle trips (trip) / hour, rush hour noon 2 Vehicle trip (trip) / hour and at no-rush hour afternoon 2 Vehicle trip (trip) / hour.

Student Activity Record System is an elearning module that is used to record student activities in the context of behaviour assessment. Student and teacher sent datas in the form of photos, videos, texts and geolocation coordinates. With the number of requests sent by the user, the load from the server side will continue to gain weight. It requires an efficient way to use the resources on the server side, namely Central Processing Unit and memory. The using of Netty as an asynchronous event driven web server and the reactor libraries as a reactive streams implementation on the server side become the right choice to optimize Central Processing Unit and memory usage. This research emphasizes the design of system architecture and library selection that implements the concept of reactive streams on the client-server side. The reactive streams concept is applied to web dashboard and mobile application so that web and mobile application become more responsive because execution is asynchronous.

Unsignalized intersection between Jalan Sukajadi, Jalan Sukawangi, Jalan Sindang Sirna is a strategic intersection in Bandung as the main access to the North Bandung area (Ledeng and surrounding areas). The intersection is often congested, especially at peak hours. This research tried to find a solution by exercising two scenarios, i.e. scenario (1) eliminating the main conflict and scenario (2) applying Traffic Signal (APILL). Analysis conducted using the Indonesian Road Capacity Guidelines (PKJI 2014) to the traffic data collected in peak hours of three workdays, i.e. morning peak, noon peak, and afternoon peak at December 2018. The existing condition shows the degree of saturation (DJ) value of 1.31, delay (T) about 153.93 sec/pcu, a potency of queuing (PA) about 70.71 to 46.7%, and level of service at F. Scenario (1) gives a DJ value smaller than the existing condition, T remains, PA becomes bigger and the level of service still in F. Scenario (2) results in a DJ value below 0.85, T and PA gets smaller, and service level increased to level C. In accordance to the simulation results, it recommended to apply traffic signal (APILL) on the intersection to relieve the congestion.
