Abstract

The purpose of this community service is to test the effectiveness of the data processing workshop using minitab for functional planning officers.This workshop was held on April 14, 2022 at BAPPEDA KLU. This workshop was attended by 10 participants. The workshop method is lecturing statistical material and data processing practice using minitab. As for comparing the average pre-test and post-test scores of participants, the Wilcoxon Match Pairs Test method was used. The test results show z count = 21.00, while it is known that the value of z table = z (1-0.05) = 1.64. z count > z table, it means that the average post-test score is significantly higher than the average pre-test score or in other words, community service in the form of training has an effect on the data processing capabilities of planning functional employees at BAPPEDA KLU

Abstract

The Fusarium spcan infect plants and cause withered diseases, it is a pathogenic fungus that greatly harms and causes losses from crop failure in the pepper plnt and various other fungus plnts to infect nd cause losses and crop failure by 50 %. The diseases strikes, the plant from the seedling age to adulthood. The reed extract contains flavonoid and folifenol can be used as a fungicidaland it has the lethal properties of couse gero, which is an antimicrobial compound, which is intended to test the potential grass-ethanol extract as liquid fertilizer s fusarium sp. The research method used in this study is experimental in the laboratory to know the potential ethanol extract in suppress the growth of the fusarium sp the study, which observations from reeds, has fungal and antibacterial compounds that can impede the growth oh the fusarium sp.

Abstract

The world population is predicted to continue increasing. Therefore, discovering another energy resource instead of fossil oil is essential. The geothermal resource can be used as alternative renewable energy. To identify the complex geothermal system in East Java as alternative renewable energy based on the gravity anomaly. This research investigated the Gunung Pandan geothermal system. The geophysical method was used which is the gravity method. The subsurface information was investigated using the Bouger Gravity Anomaly (ABL) method. The results show that the distribution of the gravitational anomaly in the Mount Pandan complex has a residual anomaly value of -3.2 mgal to 11.7 mgal. The residual anomalous contours represent positive clusters identified as intrusive rocks that heated the fluid around the fault and the suspected reservoir. thus, forming the manifestation of Banyukuning and Selogajah with the flow zone of each manifestation classified as an outflow zone for the manifestation of Banyukuning and upflow for the manifestation of Selogajah.

Abstract

Water is a means of improving the health status of the community, its quality needs to be maintained so that it is still beneficial for human life and other living things and water control is still carried out. Improving the quality of drinking water by managing it is absolutely necessary, especially if the water comes from surface water. South Rarang Village is deemed necessary to conduct research on the concentration of lime (CaCO3) in well water in South Rarang Village because it is seen that when the community boils water taken from the well, scale develops in the water heating boilers. The sample in this study was part of the wells of the people of South Rarang Village, Terara District, East Lombok Regency. The sampling criteria used by the researchers in this study were based on the location and location of the wells in each hamlet in Rarang Selatan Village, Terara District, East Lombok Regency. Based on the results of testing well water in Rarang Selatan Village, Terara District, East Lombok Regency at the Lombok Island Public Health Laboratory, it can be concluded that the average lime content in each well in South Rarang Village has an average of 432 mg/liter

Abstract

The promotion aims to attract prospective students to enter University. Socialization can introduce higher education institutions to senior high school students. One of the most effective ways to attract prospective students is the school visit or roadshow program. This program was carried out by lecturers and students of the mathematics division, UNW FMIPA, on May 2022 at MA Abdussatar Kediri, West Lombok. The roadshow program was attacked and got a positive response from MA Abdussatar teachers and students. The activity has given students motivation, insight, and knowledge regarding the existence of a mathematics study program at Nahdlatul Wathan University Mataram. Hopefully, this program can increase the motivation of the students to continue their education to a higher level.

Abstract

Model diskret predator-prey dalam bentuk orde fraksional dibahas di penelitian ini. Pendekatan model fraksional kontinu menjadi persamaan integral nonlinier Volterra akan menghasilkan bentuk diskret yang dituju. Titik kesetimbangan populasi menjadi pokok pembahasan. Dihasilkan tiga titik kesetimbangan dengan dua di antaranya adalah titik kesetimbangan E0 = (0,0) dan titik kesetimbangan E1 = (????, 0). Titik kesetimbangan E0 = (0,0) merepresentasikan titik kepunahan, baik pada populasi prey maupun pada populasi predator. Ini disebabkan karena populasi prey yang terus menerus dimangsa oleh predator. Punahnya populasi prey menyebabkan predator kehabisan sumber makanan dan pada suatu masa akan berujung pada kepunahan populasi predator. Titik kesetimbangan ????1= (????, 0) memberikan gambaran dimana terjadi kepunahan pada populasi predator akibat dari adanya perlindungan pada populasi prey sehingga memungkinkan adanya interaksi dalam jumlah sedikit antara predator dengan prey.
