This study was presented as a pilot project in the management of spatially based fishing grounds for the Fish Catching Potential Zone (FCPZ) in the Aru Sea, Arafuru Sea and East Timor Sea (WPPNRI 718). Located at 128°-141° East (East Longitude) and [4][5][6][7][8][9][10][11]. The purpose of this study is to make a more comprehensive FCPZ thematic map and identify FCPZ based on the seasons in more specific waters. This research was conducted from January to November 2016. The location of data processing was carried out at the Computer Laboratory of the Department of PSP FPIK-IPB. The primary data used are information on fishing grounds originating from PPDPI (KKP) in the 2013-2016 period, secondary data from the Sea Map of the Hidros digitizer no.151 Papua and the surrounding Islands. Analysis and thematic map creation using MapInfo Pro 15 software. Total ZPPI results for transition season 1 (297 FCPZ), west season (264 FCPZ), east season (166 FCPZ), and transition 2 (86 FCPZ). Total FCPZ based on the territorial waters of the Aru Sea (507 FCPZ), Arafuru Sea (261 FCPZ), and the Timor Sea (45 FCPZ), Aru sea and Arafuru sea are potential fishing grounds due to aquatic fertility (high chlorophyll-a content), relatively shallow water depths and the emergence of upwelling phenomena. ABSTRAKPenelitian ini dipresentasikan sebagai langkah awal (pilot project) dalam pengelolaan daerah penangkapan ikan berbasis spasial untuk Zona Potensial Penangkapan Ikan (ZPPI) di laut Aru, Laut Arafuru dan laut Timor bagian timur (WPPNRI 718). Lokasi pada 128°-141° BT (Bujur Timur) dan 4° -11° LS (Lintang Selatan). Tujuan dari penelitian ini adalah membuat peta tematik ZPPI yang lebih komperehensif dan mengidentifikasi ZPPI berdasarkan musim pada wilayah perairan yang lebih spesifik. Penelitian ini dilakukan pada bulan Januari sampai dengan November 2016. Lokasi pengolahan data dilakukan di Laboratorium Komputer Departemen PSP FPIK-IPB. Data primer yang digunakan yakni informasi daerah penangkapan ikan yang berasal dari PPDPI (KKP) pada periode tahun 2013-2016, data sekunder dari Peta Laut digitizer Hidros no. 151 Papua dan Pulau-Pulau sekitarnya. Analisis dan pembuatan peta tematik menggunakan software MapInfo Pro 15. Hasil total ZPPI untuk musim pancaroba 1 (297 ZPPI), musim barat (264 ZPPI), musim timur (166 ZPPI), dan musim pancaroba 2 (86 ZPPI). Total ZPPI berdasarkan wilayah perairan pada Laut Aru (507 ZPPI), Laut Arafuru (261 ZPPI), dan Laut Timor (45 ZPPI), laut Aru dan laut Arafuru merupakan daerah penangkapan ikan yang potensial karena kesuburan perairan (kandungan klorofil-a yang tinggi), kedalaman perairan yang relatif dangkal dan munculnya fenomena upwelling.

This research is a mix method research with the design of sequential explanatory strategy. This research aims to know and describe students’ conceptual understanding of buffer solution material and to get student response to teaching material of multiple representation buffers (macroscopic, submicroscopic, and symbolic). Research subjects were 114 students from eleven grade of natural science class (XI MIPA 3, XI MIPA 4, and XI MIPA 5), state senior high school 12 (SMA Negeri 12) Semarang, Indonesia, academic year 2017/2018. Quantitative data was collected through a diagnostic test in the form of three-tier multiple choice test totaling 20 items and questionnaires to find out the student’s response to multiple representation of teaching materials. Qualitative data is obtained by interview to confirm student answers. Multiple representation materials validated by three validators and received very excellent results with an average score of 190.33 from 212. The average score of the questionnaire was 30.026 with a proper category, and Alpha Cronbach reliability was 0.884. The results of this study indicate that the understanding of the concept of students on the material of buffer solution as much as 47.061% understand, 29.868% less understood, 12.763% misconception, and 10.307% do not understand.

Teaching and learning activities in the classroom are part of the educational process aimed at bringing to a better state. These activities will be more meaningful if the needs and experiences of students are considered. Thus, this can improve the learning objectives which is connecting the subject matter subject to real-world problems. The purposes of this research are (1) to get student response toward teaching materials of multiple Representations-Chemoentrepreneurship (entrepreneurship in the chemistry field) and (2) to know and describe the influence of entrepreneur interest toward student learning outcomes. This research is the mixed method using by the model of sequential explanatory. Research subjects were 114 students from eleven grade of natural science class (XI MIPA 3, XI MIPA 4, and XI MIPA 5), state senior high school 12 (SMA Negeri 12) Semarang, academic year 2017/2018. Quantitative data obtained through a three-tier multiple choice test. Qualitative data collected through questionnaires to determine the response of students towards teaching materials and through questionnaires. Based on this data, we can assess of student entrepreneur interest. The teaching material was validated by three validators and it obtained very feasible results with an average score of 190.33 from 212. The average score of the response sheet questionnaire was 29,500 with good category and Alpha Cronbach reliability results of 0.871. Reliability of entrepreneurial interest questionnaire is 0.935. The results of this study indicate that entrepreneur interest of student influences on student learning outcomes (tcount 10.811 > ttable 1.660).
