PENGARUH DUKUNGAN SOSIAL TERHADAP PENYESUAIAN DIRI PADA MAHASISWA RANTAU DARI PAPUA DI UNIVERSITAS NEGERI JAKARTA
ABSTRAK
Penelitian ini bertujuan untuk menganalisis pengaruh antara dukungan sosial
terhadap penyesuaian diri pada mahasiswa rantau dari Papua di Universitas Negeri
Jakarta. Jenis penelitian ini adalah deskriptif kuantitatif. Sampel yang digunakan dalam
penelitian ini berjumlah 55 orang yaitu mahasiswa rantau dari Papua yang masih aktif
melanjutkan studinya di Universitas Negeri Jakarta. Alat ukur yang digunakan dalam
penelitian ini adalah skala penyesuaian diri (Personal Adjustment) yang dikembangkan
dari teori Schneiders (1964) dan The Multidimensional Scale of Perceived Social
Support (MSPSS) untuk mengukur variabel dukungan sosial. Berdasarkan hasil
analisis uji statistik menggunakan regresi linear sederhana dengan aplikasi SPSS versi
26, didapatkan nilai F hitung sebesar 8,534 dan F tabel sebesar 4,02. Hal tersebut
menunjukkan adanya pengaruh dukungan sosial yang signifikan terhadap penyesuaian
diri pada mahasiswa rantau dari Papua di Universitas Negeri Jakarta. Selain itu, hasil
dari penelitian ini menunjukkan nilai R square sebesar 0.139 yang artinya terdapat
pengaruh dukungan sosial secara signifikan terhadap penyesuaian diri sebesar 13,9%.

ABSTRACT
This study aims to analyze the effect of social support on self adjustment of
overseas students from Papua at State University of Jakarta. This research type is
quantitative descriptive research. The research sample consisted of 55 students from
Papua who are still actively continuing their studies at State University of Jakarta. The
measuring instrument that used in this research is the Personal Adjustment Scale which
was developed from the theory of Schneiders (1964) and The Multidimensional Scale
of Perceived Social Support (MSPSS) to measure social support variables. Based on
the results of the statistical test analysis using the simple linear regression with the
SPSS 26th version application, known that the calculated F value was 8.534 and the F
table was 4.02. This result shows that there is a significant influence of social support
on self adjustment of overseas students from Papua at State University of Jakarta. In
addition, the results of this study indicate the R square value is 0.139, which means
that social support contributes 13.9% to the self adjustment of overseas students from
Papua at State University of Jakarta.

Placement of Floating Net Cages Cultivation System Based on Current Dynamics Model in the Semak Lagoon, Indonesia
This research examines the dynamics of 3-dimensional flow and the placement of floating cages in the Semak Daun Lagoon (SDL). The research was carried out using 3-dimensional current modeling process, which is designed in four tidal conditions model in accordance with the wind and tidal pressure generation. Furthermore, this research used the discretization method to vertically determine the finite volume and sigma coordinates, therefore, the whole domain was 43,575 triangular elements. The acuration of model showed by a MAPE value of 9.9%, its shows model is a very good category. The results of the model showed that the monsoons do not have a significant effect on the current pattern and velocity in SDL, however, the dominant current dynamics are influenced by tides. In addition, the current pattern in SDL waters generally moves from the Southwest to the Northeast at low tides and vice versa. In all tidal conditions, downwelling and upwelling occurred in the middle of the lagoon, with the current pattern and velocity significantly affected by Bathymetry. Surface and vertical current velocities range from 0.002 - 0.600 m/s. However, the current velocities of 0.10 - 0.20 m/s were only found at -2 m depth. Meanwhile, the optimum current velocity for marine cultivation activities is 0.10 - 0.50 m/s, therefore the utilization of SDL waters for floating net cage system cultivation is more optimal at a depth of -2.3 m
STUDI LUASAN TERUMBU KARANG DENGAN PENGINDERAAN JAUH DI TELUK MOLAWE KABUPATEN KONAWE UTARA, SEBELUM, DISAAT, DAN SETELAH PENAMBANGAN NIKEL DI SEKITAR TELUK
ABSTRAK Tujuan dari penelitian ini adalah untuk mengetahui luasan terumbu karang sebelum penambangan nikel, saat berlangsung penambangan nikel, dan setelah penambangan tidak beraktivitas di sekitar Teluk Molawe. Maka informasi mengenai dinamika luasan terumbu karang seiring dengan aktivitas penambangan nikel dapat didokumentasikan. Metode yang digunakan dalam penelitian ini yaitu penginderaan jauh (Remote sensing) menggunakan citra Landsat dengan formulasi lyzenga yang di analisis menggunakan program Er Mapper dan ARC GIS, sehingga luasan terumbu karang pada waktu berbeda dapat dipetakan dengan jelas.

ABSTRACT The purpose of this research is to know the extent of coral reefs before nickel mining, during nickel mining, and after mining around Molawe Bay. The method used in this research is remote sensing using Landsat image with lyzenga formulation which is analyzed using Er Mapper and ARC GIS program. Result of this resarch that live coral cover in 2009 is 631,13 Ha (68.12%) during nickel mining in 2013 has decreased drastically by 23.9% to 409.25 Ha (44.52%), while 2017 after nickel mining was stopped in 2013, live coral cover to increase again to 583.28 Ha (58.68%) with the percentage increase from the year 2013 - 2017 is 14.4%.
