Abstract

Teacher performance is the level of success of a person or group in carrying out their duties and responsibilitiesas well as the ability to achieve goals and standars that have been set. This study aimed to analyze theperformance of teacher to their learning in subject biology in Madrasah Aliyah Kepenuhan. This research is adescriptive study. Population weres a biology teacher and all in class XI and XII Madrasah Aliyah KepenuhanRegency Rokan Hulu. Result showed the performance of the teachers were very good creteria with percentageof 74.39% and motivation of students get adequate criteria with percentage of 68.03%. This study showed theperformance of teachers was limited to students’ motivation. Because the teacher’s performance researchinstrument (IPKG 1) biology teacher did not use learning media.

Abstract

This research aims to develop science process skills and problem-solving abilities based on outdoor learning in junior high school. This study uses a mixed method design embedded experimental models. Data was performed in the qualitative and quantitative analysis. Qualitative data analysis is used to determine the science process skills while quantitative data analysis is used to determine the increasing problem-solving ability by using normalized gain (N gain) formula. The results show that the science process skills developed at every phase comprise of making observations, formulating hypotheses, experiment, create data, classify and analyze the data, formulating its conclusions, communicate, and apply the concepts and make predictions obtained by the average value of 75.33 in the good category. While the problem-solving ability of students based on outdoor learning also increased by 0.58 in the medium category. The conclusions of this research show that the application of outdoor learning can be teacher use as an alternative to learning, so it is quite effective in developing science process skills and problem-solving abilities.

Abstract

Determination of iron nutrient content in a mixture of soil and compost with spectrophotometric method has been carried out. Metal ions Fe(II) complexed with 0.1% ortho-fenantrolin 2 mL, 0.01 M citric acid as reducing  agent  using acetat buffer at pH 4.5 and its complex was measured by using spectrophotometer UV/Vis at wavelength 515 nm, the complex stability for was 60 minutes . The highest nutrient of iron with content in soil:compost with ratio of 0.8:0.2 was 0.92% at incubation time 30 days. The lowest iron content in the mixture of soil:compost (1:0) at incubation time for  15 days was 0.58% that obtained by the regression equation y = 95.85x + 0.025 with R2=0.992. The level of nutrient iron in compost obtained lower than the maximum regulated by SNI 2.00%.

Abstract

This study intended to prove whether process image-based worksheets of geometrical optics could enhance students’ higher-order thinking (HOTS) and self-regulated learning (SRL). This was quasi-experimental research of non-equivalent control group design. This research was conducted to grade 8 junior high school students at a junior high school in Jember district studying the geometrical optic. The sample was 70 students; 35 students belonged to an experimental group and the other 35 students in a control group. The HOTS data were obtained from test results and the SRL data were collected from questionnaire results. To determine the effect of using the worksheets on the students’ HOTS and SRL, carried out was an independent t-test at a significance level of (2-tailed) α = 0.05. The results showed that the worksheets had a significant effect on the HOTS seen from α <0.05 and that the tcount>ttable at df = 68. In addition, the worksheets also owned a significant effect on the students’ SRL seen from α<0,05 and that the tcount = 14,692 (>ttable). Thus, it concluded that the learning with the worksheets had a significant influence on the junior high school students’ HOTS and SRL which are required for preparing their life in the 21st century.

Abstract

The government conducts land registration throughout the territory of the Republic of Indonesia to ensure legal certainty. Landowners are also obliged to register their land ownership rights through sporadic land registration or Systematic Land Registration. Sporadic land registration or Systematic Land Registration produces a land title certificate as proof of land rights, issued by the Regency/City Land Office. With the issuance of a land title certificate, a guarantee of legal certainty has been realized for the owner of the land title certificate, including certainty of land title status, certainty of land title subjects, and certainty of land title objects. A guarantee of legal protection is also realized for the owner of the land title certificate, namely the ownership of the land title certificate cannot receive interference or lawsuits from other parties and the land title certificate cannot be withdrawn or cancelled by anyone.   Abstrak Perlindungan Hukum dan Kepastian Hukum Kepemilikan Tanah: Pengabdian Masyarakat di Tambak Kemerakan-Sidoarjo.Pemerintah mengadakan pendaftaran tanah di seluruh wilayah Negara Republik Indonesia dalam rangka menjamin kepastian hukum. Pemilik tanah juga berkewajiban mendaftarkan tanah Hak Miliknya melalui pendaftaran tanah secara sporadik atau Pendaftaran Tanah Sistematik Lengkap. Pendaftaran tanah secara sporadik atau Pendaftaran Tanah Sistematik Lengkap menghasilkan sertipikat hak atas tanah sebagai surat tanda bukti hak atas tanah, yang diterbitkan oleh Kantor Pertanahan Kabupaten/Kota. Dengan diterbitkan sertipikat hak atas tanah terwujud jaminan kepastian hukum bagi pemilik sertipikat hak atas tanah, meliputi kepastian status hak atas tanah, kepastian subjek hak atas tanah, dan kepastian objek hak atas tanah. Juga terwujud jaminan perlindungan hukum bagi pemilik sertipikat hak atas tanah, yaitu pemilik sertipikat hak atas tanah tidak mendapatkan gangguan atau gugatan dari siapapun dan sertipikat hak atas tanah tidak dapat dibatalkan oleh siapapun.
