Perbandingan Motivasi Belajar Peserta Didik Berlatar Belakang Petani dan Nelayan di SDI Aeteke Kecamatan Lio Timur Kabupaten Ende Tahun 2020

This study was conducted to determine whether there is a difference in learning motivation between students from farmers family and fishermen family at SDI Aeteke. The research problem is formulated as follows: 1). How is the learning motivation of farmers' students? 2). How is the learning motivation of fishermen's children? The research method used is descriptive quantitative, with comparative analysis to determine the differences in learning motivation between farmers' children and fishermen's children. The results showed that at SDI Aeteke there was no significant difference in learning motivation between students from farmer family backgrounds and fishermen's children, where the learning motivation score of students from farming family backgrounds was 78.5% while students from fishermen family backgrounds were 77. 9% or only 0.6% difference. However, both of them have the highest and lowest scores on different indicators where students from farming family backgrounds have high motivation scores on the interest indicator and the lowest on the student self-awareness indicator, while students with fishing family backgrounds have high motivation scores on the indicator of the desire to succeed and the lowest indicator of the condition of the student learning environment

Field theoretic calculation of the surface tension for a model electrolyte system

We carry out the calculation of the surface tension for a model electrolyte to first order in a cumulant expansion about a free field theory equivalent to the Debye-H\"uckel approximation. In contrast with previous calculations, the surface tension is calculated directly without recourse to integrating thermodynamic relations. The system considered is a monovalent electrolyte with a region at the interface, of width h, from which the ionic species are excluded. In the case where the external dielectric constant epsilon_0 is smaller than the electrolyte solution's dielectric constant epsilon we show that the calculation at this order can be fully regularized. In the case where h is taken to be zero the Onsager-Samaras limiting law for the excess surface tension of dilute electrolyte solutions is recovered, with corrections coming from a non-zero value of epsilon_0/epsilon.Comment: LaTeX, 14 pages, 3 figures, 1 tabl

Etnomatematika: Konten Matematika Sekolah Dasar pada Rumah Adat di Kampung Waka Ende NTT

The difficulty of elementary school students in learning mathematics can be overcome through contextual learning, one of which is by using a cultural context. Mathematical content is widely available in cultural elements, one of which is traditional houses. This study aims to explore elementary school math concepts in traditional houses in Waka village, Ende, NTT. This research is a qualitative research with an ethnographic approach. The process of collecting data in this study was carried out by interview, observation and documentation. The results showed that the Waka traditional house was related to elementary school mathematics.

Edukasi Kesadaran Menjaga Lingkungan Bersih di Sekolah Dasar Inpres Ende 14

The purpose of this activity is to shape the mindset of the students of the Inpres Ende 14 Elementary School as the younger generation and as family members to care and maintain the surrounding environment and students can also be used as ambassadors for cleanliness in their families and homes. This activity is expected to create a clean, comfortable and healthy environment. Therefore, environmental hygiene must be applied from an early age so that they have a far-sighted mindset and will become agents of change in their environment. The method used in this activity is the lecture method. The lecture method is used to provide students with an understanding of the importance of maintaining a clean and healthy environment and the problems it causes and its impact on the environment as well as how to sort waste and process waste. After this activity, the waste management process will be continued. The activity begins with delivering material about a clean environment. The material presented is about the importance of keeping the environment clean, the origin of waste, the problems caused by waste and its impact on the environment. In these activities, the students seemed very enthusiastic and enthusiastic and the students also seemed very happy. After delivering the material, it was followed by cleaning the school environment and its surroundings as an application of lecture activities

Comparison of absolute gain photometric calibration between Planck/HFI and Herschel/SPIRE at 545 and 857 GHz

We compare the absolute gain photometric calibration of the Planck/HFI and Herschel/SPIRE instruments on diffuse emission. The absolute calibration of HFI and SPIRE each relies on planet flux measurements and comparison with theoretical far-infrared emission models of planetary atmospheres. We measure the photometric cross calibration between the instruments at two overlapping bands, 545 GHz / 500 $\mu$m and 857 GHz / 350 $\mu$m. The SPIRE maps used have been processed in the Herschel Interactive Processing Environment (Version 12) and the HFI data are from the 2015 Public Data Release 2. For our study we used 15 large fields observed with SPIRE, which cover a total of about 120 deg^2. We have selected these fields carefully to provide high signal-to-noise ratio, avoid residual systematics in the SPIRE maps, and span a wide range of surface brightness. The HFI maps are bandpass-corrected to match the emission observed by the SPIRE bandpasses. The SPIRE maps are convolved to match the HFI beam and put on a common pixel grid. We measure the cross-calibration relative gain between the instruments using two methods in each field, pixel-to-pixel correlation and angular power spectrum measurements. The SPIRE / HFI relative gains are 1.047 ($\pm$ 0.0069) and 1.003 ($\pm$ 0.0080) at 545 and 857 GHz, respectively, indicating very good agreement between the instruments. These relative gains deviate from unity by much less than the uncertainty of the absolute extended emission calibration, which is about 6.4% and 9.5% for HFI and SPIRE, respectively, but the deviations are comparable to the values 1.4% and 5.5% for HFI and SPIRE if the uncertainty from models of the common calibrator can be discounted. Of the 5.5% uncertainty for SPIRE, 4% arises from the uncertainty of the effective beam solid angle, which impacts the adopted SPIRE point source to extended source unit conversion factor (Abridged)Comment: 13 pages, 10 figures; Incorporates revisions in response to referee comments; cross calibration factors unchange

Power Spectrum Analysis of Far-IR Background Fluctuations in 160 Micron Maps From the Multiband Imaging Photometer for Spitzer

We describe data reduction and analysis of fluctuations in the cosmic far-IR background (CFIB) in observations with the Multiband Imaging Photometer for Spitzer (MIPS) instrument 160 micron detectors. We analyzed observations of an 8.5 square degree region in the Lockman Hole, part of the largest low-cirrus mapping observation with this instrument. We measured the power spectrum of the CFIB in these observations by fitting a power law to the IR cirrus component, the dominant foreground contaminant, and subtracting this cirrus signal. The CFIB power spectrum in the range 0.2 arc min^{-1} <k< 0.5 arc min^{-1} is consistent with previous measurements of a relatively flat component. However, we find a large power excess at low k, which falls steeply to the flat component in the range 0.03 arc min^{-1} <k< 0.1 arc min^{-1}. This low-k power spectrum excess is consistent with predictions of a source clustering "signature". This is the first report of such a detection in the far-IR.Comment: This is the version of the paper accepted by A&A, which includes various changes and new material.
