Abstract

AbstrakTelah dilakukan pengukuran resistivitas dan dielektrisitas tanah perkebunan Apel di Malang. Pengukuran resistivitas dilakukan dengan metode Geolistrik dan dielektrisitas dengan menggunakan Ground Penetrating Radar (GPR). Metode Geolistrik dilakukan dengan konfigurasi dipole-dipole dengan teknik sounding –mapping pada tiga lintasan area perkebunan seluas 1800 m2 dan satu lintasan pada area lapangan di sebelah perkebunan. Sementara itu, metode GPR diterapkan pada dua pohon apel untuk mengidentifikasi sistem perakaran apel. Pengukuran resistivitas dilakukan di perkebunan Apel desa Bengkaras Pujon, Malang sedangkan GPR dilakukan di perkebunan Poncokusumo Malang. Dari hasil pengolahan data resistivitas dengan menggunakan software Res2dinv diperoleh hasil nilai resistivitas dari keempat lintasan adalah: lintasan pertama 4,83 – 22094 Wm, lintasan kedua 6,69 – 4947 Wm, lintasan ketiga 14,1 – 178 Wm dan lintasan keempat 4,50 – 20025 Wm. Dari data tersebut secara keseluruhan belum dapat dibedakan dengan jelas nilai resistivitas antara daerah perkebunan dengan bukan perkebunan di lingkungan penelitian. Sementara itu dari pengukuran GPR diperoleh jangkauan pengukuran mencapai kedalaman 2,18 meter dan jangkauan kedalaman akar apel 1.9 meter. Rentang nilai konstanta dielektrik yang diperoleh 0,1 – 8,8 F/m. Nilai konstanta dielektrik akar 4,9 F/m. Kata kunci: Resistivitas, dielektrisitas, tanah, perkebunan apel AbstractThe resistivity and dielectric properties of Apple’s soil plantation area in Malang have been measured.  Resistivity measurement was done using geo-electrical methods and dielectric properties was measured using ground penetrating radar (GPR). Configuration of geo-electrical methods in this research is dipole-dipole and sounding –mapping technique. We have three line measurement of geo-electrical measurement for an area 1800 m2 and one line on the football yard beside of the apple plantation in Bengkaras village Pujon, Malang. Meanwhile, GPR methods was conducted on two apple trees to identify apple root system in apple plantation in Poncokusumo village Malang. The result of this research based on data analysis using Res2dinv software shows the resistivity value of four line, that are 4,83 – 22094 Wm for line number one, 6,69 – 4947 Wm  for second line, 14,1 – 178 Wm for line number three and 4,50 – 20025 Wm for line number four. From the data, generally, we cannot distinguish clearly of resistivity value of apple plantation and football yard. On the other hand, GPR measurement we can describe the maximum depth of penetrate is about 2,18 meter and the depth of root system is about 1.9 meter. The range of dielectric value is between 0,1 to 8.8 F/m and the dielectric constant of root is about 4,9 F/m. Keywords: Resistivity, dielectric, soil, apple plantation

Abstract

Research that uses the Schlumberger configuration resistivity method had been conducted in Cangar. The purpose of this study is to identify cracks/faults and potential hot springs use resistivity well analysis and correlate it with rock lithology in Cangar, East Java. Data acquisition is carried out using 3 tracks with 10 sounding points. The space between points is 50 meters. The rock resistivity values obtained were 9945 Ωm, 7360 Ωm, and 5573 Ωm which were thought to be breccia layers and functioned as hot springs. This estimation is strengthened by the existence of a layer of breccia-andesite because this layer is very good as a water reservoir. In addition, based on the lateral cross-section on lane 1, there was a decrease in boulder-sized breccia-andesite layers; this decrease was the production of faults.

Abstract

The purpose of this study was to find out the effect of the Problem Based Learning Model with mind mapping assistance on students' critical thinking skills on vibration material at MTsN 5 Tulungagung, and to determine the effect of the Problem Based Learning Model with mind mapping assistance on critical thinking skills on vibration material at MTsN 5 Tulungagung. This study uses a quantitative approach with a type of quasi-experimental research. The design form used is Pretest-posttest control group design, with class selection using cluster random sampling technique.  Data collection techniques using tests and documentation. The results of this study indicate that there is an effect between the Problem Based Learning learning model assisted by mind mapping on students' critical thinking skills on Vibration Material class VIII MTsN 5 Tulungagung with the acquisition of sig. (2-tailed) 0.00 <0.05 with the effect of the Problem Based Learning learning model assisted by mind mapping on the critical thinking skills of students in the Vibration Material of class VIII MTsN 5 Tulungagung of 0.7 or 76% classified as medium.

Abstract

Penelitian ini bertujuan mengembangkan bahan ajar fisika berbasis flipbook yang valid, praktis, dan efektif pada materi Usaha dan Energi. Latar belakang penelitian adalah rendahnya efektivitas pembelajaran fisika di SMA Negeri 1 Srengat. Metode yang digunakan adalah Research and Development (R&D) dengan model ADDIE. Subjek penelitian mencakup dua validator media, dua validator materi, serta peserta didik kelas X dan XI. Sampel uji kepraktisan melibatkan 33 peserta didik kelas XI, sedangkan uji efektivitas melibatkan 70 peserta didik kelas X yang dibagi dalam kelas eksperimen (34 peserta didik) dan kontrol (36 peserta didik). Desain eksperimen yang digunakan adalah posttest only control group design. Teknik pengumpulan data meliputi wawancara, angket, dan tes. Hasil validasi menunjukkan skor rata-rata 3,80 (sangat valid), dan uji kepraktisan menghasilkan skor 3,54 (sangat praktis). Uji efektivitas menunjukkan perbedaan signifikan antara kedua kelas, dengan nilai effect size sebesar 1,349 (kategori tinggi).

Abstract

Indonesia is a country with significant renewable energy potential. One of the sources of renewable energy is the micro-hydro power plant in Tulungagung, an area traversed by large rivers. This study aims to analyze the potential of Micro-Hydro Power Plants (PLTMH) on tributaries in Tulungagung. The research covers 14 rivers in Tulungagung, with location selection based on several criteria. The results indicate that out of the 14 surveyed locations, 10 rivers have the potential to be developed into PLTMH. These rivers include: Srabah River with a capacity of 6.45 kW, Buntaran River with 5.88 kW, Ngranti River with 14.97 kW, Dawuhan River with 7.72 kW, Kalimas River with 39.28 kW, Jajar River with 7.78 kW, Jambu River with 5.35 kW, Ariyojeding River (Lodagung flow) with 248.13 kW, Gilang River with 12.16 kW, Petung River with 12.66 kW. The river with the highest potential and most suitable for a PLTMH is the Aryojeding River, which has the largest capacity at 248.13 kW.
