Abstract

Leadership is a process of influencing, directing or giving an example of employees in order to achieve the objectives of the organization and is a key element in the effectiveness of the organization. In addition to the style of leadership, the success of an organization or company in achieving its objectives can also be influenced by the commitment of the organization. Where organizational commitment is a commitment created by each individual for the betterment of the organization. The purpose of this research is to obtain a model of leadership style and organizational commitment to job satisfaction and employee performance, and determine the factors that influence job satisfaction and employee performance using SEM with Bayesian approach. This research was conducted at Statistics FNI employees in Malang, with 15 people. The result of this study showed that the measurement model, all significant indicators measure each latent variable. Meanwhile in the structural model, it was concluded there are a significant difference between the variables of Leadership Style and Organizational Commitment toward Job Satisfaction directly as well as a significant difference between Job Satisfaction on Employee Performance. As for the influence of Leadership Style and variable Organizational Commitment on Employee Performance directly declared insignificant.

Abstract

Students are part of the community who have an income. The income of students are pocket money, scholarships, part-time jobs and so forth. They are trying to become trendsetter in get dress and . The consumption patterns are very influential in behavior of saving. If the savings increases not only the public funds will increase but also the investment. If the investment increases the economic growth has also increased. The purpose of this research is to estimate multiple regression parameters using REML methods in modeling the student’s saving in Faculty of Mathematics and Natural Science, Brawijaya University. The variables used were X_1= The student’s age (years), X_2= The amount of income of student’s parent (thousand rupiah), X_3= The amount of student’s pocket money (thousand rupiah), X_4= The amount of student’s additional income (thousand rupiah), X_5= The amount of student’s consumption (thousand rupiah) and Y= The amount of student’s saving (thousand rupiah).REML method can overcome heteroscedasticity error variance and unbiased estimator. The model of student’s saving is using REML method as follows:Y ̂_i= -1855,66 +121,5 X_1+0.0098X_2+0.0524 X_3+0.5587 X_4-0.5851X_5Student’s saving affected by: student’s age (years), the amount of student’s additional income (thousand rupiah), and the amount of student’s consumption (thousand rupiah).

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara tingkat pemberian dosis Biopestisida Crude Extract Tembakau dengan persen kematian hama Kutu Daun Hijau (Aphis gossypii) pada tanaman jeruk, sehingga dapat dilakukan pendugaan tingkat toksisitas dosis yang efektif (LD50) dalam mematikan hama. Metode analisis yang tepat digunakan pada permasalahan ini adalah analisis regresi nonlinear kuadratik. Data yang digunakan dalam penelitian ini merupakan data sekunder dengan variabel responnya adalah persen kematian dari hama Kutu Daun Hijau (Aphis gossypii) yang disebabkan oleh pemberian dosis uji Biopestisida Crude Extraxct Tembakau. Penelitian ini dilakukan di laboratorium entomologi Balai Penelitian Tanaman Jeruk dan Buah Subtropika (BALITJESTRO) Kota Batu. Hasil analisis menunjukkan bahwa tingkat dosis Biopestisida Crude Extract Tembakau memiliki hubungan nonlinear (kuadratik) dengan persen kematian hama Kutu Daun Hijau (Aphis gossypii) pada tanaman jeruk. Dari hasil analisis menggunakan metode analisis regresi kuadratik, didapatkan informasi diantaranya tingkat dosis Biopestisida Crude Extract Tembakau yang efektif untuk mematikan 50% Kutu Daun Hijau (Aphis gossypii) dalam jangka waktu 24 jam adalah sebesar 2.46%; dalam jangka waktu 48 jam adalah sebesar 0.76%; dan dalam jangka waktu 72 jam adalah sebesar 0.73%.

Abstract

Prinsip kerja dari produksi semen adalah memproduksi ketika terdapat permintaan dan memproduksi untuk disimpan. Sehingga dapat dikatakan salah satu keberhasilan produksi semen di PT. Semen Gresik Pabrik Rembang diukur dengan tercapai pemenuhan permintaan semen. Salah satu pertimbangan dalam memproduksi semen yaitu informasi mengenai jumlah permintaan semen pada periode-periode selanjutnya. Untuk mendapatkan informasi mengenai jumlah permintaan semen, maka perlu dilakukan peramalan. Salah satu analisis statistika yang dapat digunakan adalah metode Triple Exponential Smoothing Winter. Analisis tersebut menghasilkan nilai konstanta optimum = 1, = 0, dan = 0,1. Hasil analisis peramalan jumlah permintaan semen bulan Juli hingga Desember 2019 berturu-turut sebanyak 178.430; 190.092; 215.215; 252.192; 239.216; 234.845 Juta ton semen. Kata Kunci: Permintaan Semen, Peramalan, Triple Exponential Smoothing Winter, Semen Gresik Pabrik Rembang.

Abstract

Increasing population growth can lead to the availability of agricultural land becomes smaller, it causes an imbalance of farmers population in a region with an area of agricultural land there, so the population pressure on agricultural land will be greater so that the region no longer can meet the needs of food population. If this happends continue then it is not impossible that the production has not proportional to the needs of existing population, and resulted in the carrying capacity of agricultural land will be smaller. So the analysis of the carrying capacity of agricultural land needs to be done to determine the ability of the land to provide food for the population needs in a given area. Carrying capacity of agricultural land is a function of several spatial variables may give effect in spatial linkages. The model can explain the relationship between variables that have a spatial relationship is called spatial regression models. One of the effective spatial regression models to estimate the effects of data that has a spatial dependency in the response variable is Spatial Autoregressive (SAR) model. Agricultural land supporting food is a phenomenon of spatial autocorrelation. Based on observations made at the carrying capacity of agricultural land for food in every village in Batu City, information obtained that there is significant effects of the percentage of farmers (X1), the land area for a decent life (X2), and the amount of food crops (X3) and the coefficient dependencies on lag (ρ) to the carrying capacity of farmland food (Y).
