The purpose of this research is to develop a lithosphere module for grade X SMA / MA students using the Dicky & Carey development model and to find out the effectiveness of the developed module. This research method uses research and development. The instruments used in this study were questionnaires and tests for each learning activity. The data analysis technique of this research uses descriptive statistical analysis. In this research, five modules have been developed, namely Module I (Structure of the Lithosphere Layer), Module 2 (Endogenous Energy), Module 3 (Exogenous Energy), Module 4 (Pedosphere), and Module 5 (Soil Erosion). Based on the results of field trials, this learning module has succeeded in showing benefits.

This paper describes field trials for two different technologies (built in two commercial products) for leak detection, location and quantification systems (LDS). Modified Compensated Volumetric Balance was tested against SPRT Statistical Analysis, and the obtained results were analyzed/commented. The tests were carried out in a 43 km long 20 in. pipeline (PREPSP), carrying different batches of crude oils, located in the state of Bahia, Brazil. Actual leaks under shut in, steady state, pump transient startup and shutdown operational conditions were introduced, and the performance of both technologies analysed. For each of those conditions and technologies, a sensitivity curve was plotted, leak location and its quantification was tabled, compared and commented. Finally, reliability data for both technologies (essentially, number of false alarms and non-expected misbehavior) were gathered for a two weeks testing period.

Abstract: This study aims to determine the feasibility of learning media Scrapbook on Solar System materials, as well as to know the response of teachers and learners to the development of learning media Scrapbook on Solar System materia ls.This research is a type of research and development (R & D). The steps of research and development are guided by Brog and Gall model with seven stages. This research was conducted at UIN Raden Intan Lampung, SMPN 21 Bandar Lampung, SMPN 13 Bandar Lampung, and Mts Muhammadiyah Bandar Lampung. The instrument of data collection used is questionnaire or questionnaire. Technique of collecting data using questionnaire with Likert scale. Data analysis techniques used are qualitative descriptive analysis techniques and descriptive statistical analysis. Media feasibility results based on the assessment of media experts and material experts are included in very good criteria. As well as the outcomes of teacher and learner responses through small group trials and field trials were assessed with very good criteria. Scrapbook learning media on the material of the Solar System as a whole received an assessment that is included in the criteria very well, so it is worthy to be used as a medium of learning.Abstrak: Penelitian ini bertujuan untuk mengetahui kelayakan media pembelajaran Scrapbook pada materi Tata Surya, serta mengetahui respon guru dan peserta didik terhadap pengembangan media pembelajaran Scrapbook pada materi Tata Surya. Penelitian ini merupakan jenis penelitian dan pengembangan (R&D). Langkah-langkah penelitian dan pengembangan berpedoman pada model Brog and Gall dengan tujuh tahapan. Penelitian ini dilaksanakan di UIN Raden Intan Lampung, SMPN 21 Bandar Lampung, SMPN 13 Bandar Lampung, dan Mts Muhammadiyah Bandar Lampung. Instrumen pengumpulan data yang digunakan adalah angket atau kuesioner. Teknik pengumpulan data menggunakan angket dengan skala Likert. Teknik analisis data yang digunakan yaitu teknik analisis deskriptif kualitatif dan analisis statistik deskriptif. Hasil kelayakan media berdasarkan penilaian ahli media dan ahli materi termasuk dalam kriteria sangat baik. Serta hasil respon guru dan peserta didik melalui uji coba kelompok kecil dan uji coba lapangan memperoleh penilaian dengan kriteria sangat baik. Media  pembelajaran Scrapbook pada materi Tata Surya secara keseluruhan memperoleh penilaian yang termasuk dalam kriteria sangat baik, sehingga layak digunakan sebagai media pembelajaran.

SUMMARYThe present method of analysis of data from comparative field trials of acuterodenticides was compared with two alternative methods of analysis, using computer simulation techniques. One of the proposed alternative analyses, the use of post-treatment census takes as a percentage of pre-treatment census takes in an analysis of variance, was found to be more accurate, to avoid a theoretical difficulty associated with the present method, and is computationally much simpler.
