Judul: Analisis Faktor-Faktor yang Mempengaruhi Kriminalitas di Jawa dan Sumatera Tahun 2010-2019
Abstrak: Di satu pihak, tindak kriminalitas dapat mempengaruhi keputusan masyarakat dalam melakukan kegiatan ekonomi dan di pihak lain, kondisi ekonomi dapat mendorong terjadinya kriminalitas. Namun demikian, di Jawa dan Sumatera untuk tahun 2010- 2019 meskipun kondisi ekonominya relative baik, angka kejahatannya merupakan yang tertinggi di Indonesa. Oleh karena itu, tujuan utama penelitian ini adalah untuk menganalisis faktor-faktor yang mempengaruhi kriminalitas di Jawa dan Sumatera berdasarkan aspek ekonomi, sosial, kelembagaan dan teknologi. Metode analisis yang digunakan dalam penelitian ini adalah analisis ekonometrik dataapanel, dengan data yang diperoleh dari Badan Pusat Statistik Republik Indonesia. Hasil analisis menunjukkan bahwa faktor yang signifikan mempengaruhi kriminalitas dari sisi ekonomi adalah PDRB per kapita, dan ketimpangan pendapatan; dari sisi sosial adalah pendidikan; dan dari sisi kelembagaan adalah kebijakan pemerintah; Sementara variabel teknologi memiliki pengaruh yang positif namun tidak signifikan terhadap kriminalitas., On the one hand, criminal acts can influence people's decisions to carry out economic activities and on the other hand, economic conditions can encourage crime. However, in Java and Sumatra for 2010-2019, although the economic conditions are relatively good, the crime rate is the highest in Indonesia. Thus, this research pursuits to analyze the factors that influence crime in Java and Sumatera from the economic, social, institutional and technological aspects. The analytical method used in this research is econometric analysis of panel data with data obtained from the Central Bureau of Statistics of the Republic of Indonesia. The results of the analysis show that the factors that significantly affect crime from an economic perspective are GRDP per capita, and income inequality; from the social perspective is education; and from the institutional side is government policy. Meanwhile, technology have a positive but not significant effect on crime.

Judul: The Influence of Education, Unemployment, Income Inequality, and Poverty on Crime in Indonesia (Year Period 2015-2019)
Abstrak: Pengaruh Pendidikan, Pengangguran, Ketimpangan Pendapatan, serta Kemiskinan Terhadap Kriminalitas di Indonesia (Periode Tahun 2015-2019). Dibimbing oleh MUHAMMAD FINDI. Kriminalitas merupakan salah satu permasalahan yang yang berkaitan dengan perlindungan keamanan dan kenyamanan seseorang. Angka kejahatan Indonesia 2015-2017 mengalami penurunan namun masih perlu untuk terus ditekan agar masyarakat dapat dengan aman dan nyaman melakukan kegiatan termasuk kegiatan-kegiatan ekonomi. Selain itu kerugian yang diakibatkan oleh kejadian kriminalitas yang terjadi tidak hanya dirasakan oleh korban, namun juga pelaku dan pemerintah. Penelitian ini dilakukan dengan tujuan untuk mengatahui pengaruh faktor pendidikan, pengangguran, ketimpangan pendapatan, serta kemiskinan terhadap kriminalitas di Indonesia pada tahun 2015-2019. Pada penelitian ini metode yang digunakan adalah analisis data panel dengan data yang digunakan adalah data sekunder. Data diperoleh dari Badan Pusat Statistik Republik Indonesia. Hasil penelitian ini adalah variabel pendidikan dan pengangguran berpengaruh negatif signifikan terhadap kriminalitas. Variabel ketimpangan pendapatan dan kemiskinan berpengaruh posiftif signifikan terhadap kriminalitas di Indonesia. Kata kunci: kriminalitas, pendidikan, pengangguran, ketimpangan pendapatan, kemiskinan., The Influence of Education, Unemployment, Income Inequality, and Poverty on Crime in Indonesia (Year Period 2015-2019). Supervised by MUHAMMAD FINDI. Crime is one of the problems related to the protection of a person's security and comfort. Indonesia's 2015-2017 crime rate has decreased but is still needs to be suppressed so that people can safely and comfortably carry out activities including economic activities. In addition, the losses caused by criminal activity that occur are not only felt by the victims, but also the perpetrators and the government. This research was conducted with the aim of knowing the impact of education, unemployment, income inequality, and poverty on crime in Indonesia in 2015-2019. In this study, the method used is panel data analysis with secondary data used. Data obtained from the Central Statistics Agency of the Republic of Indonesia (BPS Indonesia). The results of this research are the variables of education and unemployment have a significant negative effect on crime. The variables of income inequality and poverty have a significant positive effect on crime in Indonesia. Keywords: crime, education, unemployment, income inequality, poverty.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
