Abstract. Public transport facilities are fundamental needs as population growth and society mobility increases. Nowadays, Balikpapan is one of the cities growing quite rapidly, including the level of society mobility. If it is not anticipated, this could lead Balikpapan becomes a crowded city such as Jakarta, Surabaya, Bandung and others. One of public transportation in Balikpapan is angkot which has capacity only about 10 passengers. Others are taxi and online transportation such as Gojek, Go-Car, and Grab. These are not yet the appropriate solution for public transportation services for all levels of society.  Thus, it needs to be developed the integrated mass public transportation system in Balikpapan and become an alternative solution to the problems. One of the public demands in using public transportation service is passengers can reach any location from anywhere (strongly connected). Therefore, it is necessary to design the route of mass public transport system such as city busway.  In this paper it is called Trans Balikpapan Busway. In this paper, we use graph concept to design Trans Balikpapan Busway route. The result is the design of Transbalikpapan Busway route. It is ilustrated by a directed graph. The matrix that represents the graph has unique eigen value, so that the graph is strongly connected. It connects all districts in Balikpapan with places that people ussually visit such as schools/campuses, shops, malls, hospitals, terminals, air port, harbour, institutions, companies, recreation destinations, etc. Abstrak. Fasilitas transportasi umum merupakan kebutuhan vital seiring pertumbuhan penduduk dan mobilitas masyarakat meningkat. Saat ini, Balikpapan adalah salah satu kota yang berkembang cukup pesat, termasuk tingkat mobilitas masyarakat. Jika tidak diantisipasi, ini dapat menyebabkan Balikpapan menjadi kota yang padat seperti Jakarta, Surabaya, Bandung dan lain-lain. Salah satu angkutan umum di Balikpapan adalah angkutan kota yang kapasitasnya hanya sekitar 10 penumpang. Angkutan umum lainnya adalah taksi argo dan transportasi online seperti Gojek, Go-Car, dan Grab. Itu pun belum menjadi solusi yang tepat untuk layanan transportasi umum bagi semua lapisan masyakat. Dengan demikian, perlu dikembangkan sistem transportasi umum massal terpadu di Balikpapan dan menjadi solusi alternatif untuk masalah tersebut. Salah satu tuntutan masyarakat dalam menggunakan layanan angkutan umum adalah penumpang dapat mencapai suatu lokasi dari mana saja (strongly connected). Oleh karena itu, perlu dirancang rute sistem transportasi umum massal seperti moda bus kota. Dalam hal ini dinamakan Trans Balikpapan Busway. Dalam paper ini, digunakan konsep graf untuk merancang rute Trans Balikpapan Busway. Hasil penelitian ini adalah desain rute Transbalikpapan Busway. Jaringan Transbalikpapan Busway diilustrasikan dalam graf berarah. Matriks yang mewakili graf tersebut memiliki nilai eigen yang tunggal/unik, sehingga dapat disimpulkan graf tersebut strongly connected. Jaringan Transbalikpapan Busway menghubungkan semua kecamatan di Balikpapan beserta tempat-tempat yang biasa dikunjungi oleh masyarakat seperti sekolah/kampus, pasar, mall, rumah sakit, terminal, bandara, pelabuhan, instansi, perusahaan, tujuan rekreasi dan lain-lain.

Dalam Peraturan Presiden (Perpres) No. 22 Tahun 2009 disebutkan bahwa dua sasaran dari upaya diversifikasi pangan masyarakat Indonesia meliputi perbaikan pola konsumsi pangan yang beragam, bergizi, dan seimbang serta mengurangi konsumsi beras per kapita sebesar 1,5% per tahun. Upaya tersebut dilakukanuntuk menghindari ketergantungan pada satu jenis pangan pokok yaitu beras. Disisi lain ketersediaan pangan lokal merupakan alternatif terbaik sebagai pengganti beras karena lebih mudah dijangkau secara sik maupun ekonomi, seperti jagung, singkong, ubi jalar, sagu, gembili, yang biasa dikenal dengan istilah non-beras. Pada jurnal ini dibahas permasalahan kendali optimal model diversifikasi beras dan non-beras dengan penerapan target akhir konsumsi. Target akhir konsumsi adalah tingkat konsumsi beras dan non-beras yang diharapkan oleh pemerintah pada tahun yang sudah ditentukan. Model dinamik yang digunakan untuk mengintepretasikan adalah Model Lotka-Volterra. Persentase tingkat konsumsi beras dan non-beras dijadikan sebagai variabel pengendali yang bertujuan untuk meminimumkan biaya. Metode penyelesaian yang digunakan adalah Prinsip Minimum Pontryagin. Berdasarkan hasil simulasi ditunjukkan bahwa konsumsi beras menurun secara optimal sedangkan konsumsi non-beras meningkat, sehingga biaya yang dikeluarkan minimum.

In this thesis, the analysis of vehicles' determination of speed and volume in the traffic flow will be discussed by approach time. The analyzation of vehicles' speed and volume done by estimated on macroscopic term of traffic flow in the traffic jam with Extended Kalman Filter (EKF) method. The term of macroscopic views with measured the traffic variable by density the flow rate the flow rate of vehicle and also the vehicle speed's average. In the estimating process, forward difference scheme is implemented to the model and error are measured by Root Mean Square Error. The result showed that the estimation the average of the vehicle?s relative speed in a segment decreased when its volume of vehicle is increased and vice versa.

Inverter is an electronic circuit that convert electric voltage with direct current (DC) to alternating current (AC). One of the commonly used inverter configuration is H-Bridge circuit. Inverter with H-Bridge circuit does not need voltage-balanced diode or capacitor to operate and can be cascaded to obtain multilevel output voltage. H-Bridge circuit works by adjusting the combination of switches that were enabled. One of the commonly used switches is Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The advantages of MOSFET as switching components are its fast switching speed and it did not cause current tail. Therefore, the writing of this paper aims to design a 12V DC to 220V AC 50Hz single-phase inverter with H-Bridge MOSFET circuit. The design stage begins with determining the specifications of the inverter, creating a block diagram of the inverter, determining the required components, and calculating the required parameters of the inverter. The designed inverter is simulated using Proteus 8.4 software. Simulation results are in accordance with the desired specification.
