Abstract

Konstruksi model matematis dari suatu fenomena dalam bidangmatematika biologi merupakan hal yang sangat penting. Salahsatunya dapat diterapkan dalam proses kemoterapi tumor. Sebagai salah satu penyakit yang mematikan, pengobatan kemoterapi tumor perlu dioptimalkan untuk mencegah proliferasi sel yang tidak terkendali. Namun proses kemoterapi yang tidak tepat, dapat berakibat fatal bagi pasien penyakit tumor. Sehingga interval waktu dan dosis yang tepat dalam kemoterapi sangat efektif untuk mengurangi ukuran tumor. Permasalahan kemoterapi tumor dimodelkan sebagai permasalahan optimal dimana penentuan dosis obat optimummerupakan fungsi tujuannya. Permasalahan optimal selanjutnyaditransformasikan menjadi permasalahan pemrograman nonlinier (PNL), yang selanjutnya diselesaikan dengan software pemrograman nonlinier (PNL).

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.

The purpose of this study was to examine the effect of Earning Per Share (EPS), Price Earning Ratio (PER), Return On Assets (ROA), and Return On Equity (ROE) on Stock Prices in Food and Beverage Companies on the Indonesia Stock Exchange in 2015 - 2018. In this study, the population is the number of Food and Beverage companies listed on the Indonesia Stock Exchange from 2015-2018, totaling 24 companies. The sample in this research is 14 companies x 4 years of observation = 56 samples using purposive sampling method. The results showed that the t-count value of the t-count Earning Per Share (X1) was 4.114 and the probability value was less than 0.05, which was 0.000. This shows that the variable Earning Per Share (X1) has a significant effect on stock prices. Thus, the first hypothesis in this study is accepted. The t-count value of the Price Earning Ratio (X2) is -1.301 and the probability value is greater than 0.05, which is equal to 0.199. This shows that the variable Price Earning Ratio (X2) has no significant effect on stock prices. Thus, the second hypothesis in this study was rejected. The t-count value of Return On Assets (X3) is equal to 8.366 and the probability value is less than 0.05, which is 0.000. This matter shows that the variable Return On Assets (X3) has a positive effect on stock prices. Thus, the third hypothesis in this study is accepted. The t-count value of Return On Equity (X4) is -1.504 and the probability value is greater than 0.05, which is 0.139. This shows that the variable Return On Equity (X4) has no significant effect on stock prices. Thus, the fourth hypothesis in this study was rejected
