Judul: An analysis of environmental quality of medium and small cities in Kalimantan.
Abstrak: Based on the 2010 census, Kalimantan region inhibited by 13 787 831 people where 5 799 291 people or 42.06 % among them live in urban areas. The population growth occurred because of the rising birth rate, urbanization from rural areas, as well as immigrant that coming from other areas. On one side, this condition contributes positively to abundant availability of human resources. On the other hand, this condition causes problems or negative impacts on the environment such as pollution and more intense use of urban land. Through good urban environment management, these negative impacts can be reduced. This study conducted in order to achieve a sustainable city through good environmental management. This study conducted in order to achieve a sustainable city through good environmental management. Based on population classifications, Kalimantan region consist of 52 cities. These cities divided into 5 big cities, 4 medium cities and 43 small cities. Until now, there was a tendency of urban environmental management research more focused on big cities and very limited similar researches have done in medium and small cities. As the result, information about environment management in medium and small cities is generally difficult to obtain. Therefore, in these researches medium and small cities were chosen to be the object of the research. The objectives of this research are : (1) analyzing and grouping medium and small cities in Kalimantan based on common characteristics of the environment, (2) analyzing factors that affect the medium and small cities environmental quality index in Kalimantan, (3) analyzing relationship between environmental budget allocations, solid waste management budget allocation and city environmental quality index, (4) analyzing relationship between population density and city environmental quality index and (5) developing direction in improving environmental quality for medium and small cities. The research was conducted over 14 months in the period of June 2012 to July 2013. Research area covers 47 cities in Kalimantan, which consist of 4 medium cities and 43 small cities. Analysis of the data used in this study including: (1) Cluster analysis, (2) Principal component analysis and (3) Panel data analysis. Cluster analysis was used to group cities based on common characteristics related to environmental management. The analysis obtained 6 or 12.77 % of the cities belongs to best category, 7 or 14.89 % of the cities belongs to good category, 19 or 40.43 % of the cities belongs to sufficient category, 11 or 23.40 % of the cities belongs to bad category while the rest 4 or 8.51 % are belongs to the worst category. Principal component analysis showed that management of public area such as city park and traditional market has greatest impact on city environment quality index. While management of private area such as citizen settlements has less positive impact on city environment quality index. Panel analysis was used to get correlation between environmental management budget allocation, solid waste management budget allocation, urban area population density and environmental quality index of the cities. As the result environmental management budget allocation and solid waste management budget allocation have positive correlation with city environmental quality index.

Judul: Regional Fiscal and Human Development Quality in North Kalimantan Province
Abstrak: Tahun 1990, United Nations Development Programme (UNDP) mengeluarkan Indeks Pembangunan Manusia (IPM) sebagai salah satu indikator pengukuran keberhasilan pembangunan manusia. Provinsi Kalimantan Utara termasuk kedalam 3 provinsi dengan Produk Domestik Regional Bruto (PDRB) perkapita tertinggi di tingkat nasional, namun IPM Provinsi Kalimantan Utara berada di bawah tingkat nasional sejak 7 tahun terakhir. Berdasarkan penelitian sebelumnya, belanja pemerintah dapat menggambarkan IPM lebih dari 80 persen dan penelitian lainnya menunjukkan bahwa belanja pemerintah yang relatif besar tidak akan berdampak terhadap pembangunan jika belanja pemerintah tidak dialokasikan kepada infrastruktur. Belanja Provinsi Kalimantan Utara berada diatas rata-rata nasional. Oleh karena itu, penelitian ini bertujuan untuk menganalisi disparitas infrastruktur antar wilayah dan menganalisis dampak belanja pemerintah daerah menurut fungsinya (kesehatan, pendidikan dan ekonomi) terhadap IPM. Hasil analisis skalogram menunjukan bahwa terdapat disparitas infrastruktur antar kebupaten di Provinsi Kalimanta Utara dimana Kabupaten Tanah Tidung dan Nunukan merupakan kabupaten dengan ketersediaan infrastruktur yang relatif rendah dan sebaliknya dengan tiga kabupaten lainnya. Secara deskriptif menunjukan bahwa ada hubungan antara infrastruktur dengan IPM. Berdasarkan model ekonometrik data panel, data cross section lima kabupaten/kota dan time series tahun 2013-2019, khususnya Random Effect Model menunjukkan bahwa anggaran kesehatan berhubungan positif dengan IPM, namun tidak signifikan; sedangkan anggaran fungsi ekonomi berdampak signifikan terhadap IPM, namun dengan arah yang tidak sesuai dengan hipotesis. Sementara masing-masing indeks (kesehatan, pendidikan dan ekonomi) tidak dipengaruhi oleh anggarannya kecuali kesehatan; peningkatan PDRB secara signifikan dapat meningkatkan masing-masing indeks dan penurunan tingkat kemiskinan secara signifikan dapat meningkatkan indeks kesehatan., In 1990, the United Nations Development Program (UNDP) issued the Human Development Index (HDI) as an indicator for measuring the success of human development. North Kalimantan Province is included in the 3 provinces with the highest per capita Gross Regional Domestic Product (PDRB) at the national level, however the HDI of North Kalimantan Province has been below the national level for the last 7 years. Based on previous research, government spending can describe HDI more than 80 percent and other studies show that relatively large government spending will not have an impact on development if government spending is not allocated to infrastructure. North Kalimantan Province spending is above the national average. Therefore, this study aims to analyze disparities in infrastructure between regions and to analyze the impact of local government spending by function (health, education and economy) on HDI. The results of the schalogram analysis show that there are disparities in infrastructure between districts in North Kalimantan Province where Tanah Tidung and Nunukan are districts with relatively low infrastructure availability and vice versa with the other three districts. Descriptively shows that there is a relationship between infrastructure and HDI. Based on the panel data econometric model, cross section data for five districts / cities and time series for 2013-2019, particularly the Random Effect Model, it shows that the health budget is positively related to HDI, but not significant; while the economic function budget has a significant impact on HDI, but in a direction that is not in accordance with the hypothesis. Meanwhile each index (health, education and economy) is not influenced by its budget, except for health; a significant increase in

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
