<p><em>Tea leaf plucking is an important activity that can determine the quantity and quality of tea production. Tea plantations characteristically have variations of slopes that affect the performance of the picking process. This study aimed to analyze the performance efficiency of tea plucking activities using plucking machines and scissors. Field data were collected from several blocks in the South Gambung and North Gambung afdeling. Data collected consisted of the elevation of the place, the slope of the land, the plucking area, plucking time, the number of pluckers, the plots length of the plucking activity, the width of the plots, and the harvested tea's weight. The data collected were processed into field capacity and tea plucking performance efficiency, which were then analyzed descriptively. Results showed that the slope of the land has an effect on work efficiency of 3.00%-8.68%. The effective and theoretical field capacity of tea plucking machines is 0.14 hectares per hour and 0.20 hectares per hour, respectively, while the scissors is 0.015 hectares per hour and 0.020 hectares per hour. The quality of tea harvested with machines that meet the requirements is 44.10%, better than scissors harvested, which is only 28.09%.</em></p>

In order to research the groundwater quality of the Taikang Formation in Tertiary in west of Daqing Oilfield, resistivity logging data of 140 wells in the study area were used to analyze the relations between the groundwater quality and sedimentary sand body and buried depth. The south area of Hongweixing well area and the east of Xishuiyuan well area, including Ranghulu, Qianjincun, Dulitun and Nanshuiyuan well area are favorable for high quality groundwater. The shallower buried water quality is better than the deeper buried water quality of the Taikang Formation in Tertiary. The research provides the evidences to evaluate the groundwater quality in west Daqing Oilfield and determine specific well location, improving the efficiency of exploring the underground drinking water.

<p>Despite the large applicability of the field capacity (FC) concept in hydrology and engineering, it presents various ambiguities and inconsistencies due to a lack of methodological procedure standardization. Experimental field and laboratory protocols taken from the literature were used in this study to determine the value of FC for different depths in 29 soil profiles, totaling 209 soil samples. The volumetric water content (theta) values were also determined at three suction values (6 kPa, 10 kPa, 33 kPa), along with bulk density (BD), texture (T) and organic matter content (OM). The protocols were devised based on the water processes involved in the FC concept aiming at minimizing hydraulic inconsistencies and procedural difficulty while maintaining the practical meaning of the concept. A high correlation between FC and theta(6 kPa) allowed the development of a pedotransfer function (Equation 3) quadratic for theta(6 kPa), resulting in an accurate and nearly bias-free calculation of FC for the four database geographic areas, with a global root mean squared residue (RMSR) of 0.026 m<sup>3</sup>·m<sup>-3</sup>. At the individual soil profile scale, the maximum RMSR was only 0.040 m<sup>3</sup>·m<sup>-3</sup>. The BD, T and OM data were generally of a low predicting quality regarding FC when not accompanied by the moisture variables. As all the FC values were obtained by the same experimental protocol and as the predicting quality of Equation 3 was clearly better than that of the classical method, which considers FC equal to theta(6), theta(10) or theta(33), we recommend using Equation 3 rather than the classical method, as well as the protocol presented here, to determine in-situ FC.</p>

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

Important Activity

Pembuktian dalam matematika adalah suatu aktivitas yang penting, tetapi aktivitas ini tergolong sulit bagi mahasiswa calon guru matematika. Masalah ini salah satunya dipengaruhi oleh kepercayaan-diri. Tujuan penelitian ini adalah untuk menganalisis karakteristik pencapaian kemampuan pembuktian matematis dan kepercayaan-diri mahasiswa melalui metode Moore. Penelitian ini menggunakan metode campuran bertahap yaitu tahap kuantitatif dan tahap kualitatif. Pada tahap kuantitatif disimpulkan bahwa kemampuan pembuktian pada kelas yang menggunakan metode Moore lebih baik daripada kelas yang menggunakan model pembelajaran langsung. Metode Moore dapat mengungkap proses perkembangan capaian pembelajaran mahasiswa dalam pembuktian, sehingga dosen dapat memberikan umpan balik untuk mengembangkannya. Pada tahap kualitatif, dihasilkan karakteristik kemampuan pembuktian beberapa mahasiswa. Karakteristik ini ditinjau berdasarkan respon mahasiswa terhadap masalah pembuktian. Pada pembelajaran dengan metode Moore, mahasiswa tidak diperbolehkan membuka bahan ajar, sehingga dosen harus mengikuti alur berpikir mahasiswa dan mengarahkan proses berpikirnya. Sebagai implikasi, metode Moore baik digunakan dengan catatan mahasiswa harus belajar terlebih dahulu sebelum pembelajaran di kelas.Proving in mathematics is an important activity, but this activity is classified as difficult for prospective mathematics teacher students. This problem is influenced by self-confidence. The purpose of this study was to analyze the characteristics of achievement of students' mathematical proving ability and self-confidence  through the Moore method. This study uses a phased mixed method, namely quantitative and qualitative stages. In the quantitative stage, it was produced: "Based on the overall and PAM categories, the ability to prove the class using the Moore method is better than the class that uses the direct learning model". Moore's method can reveal the process of developing student learning outcomes in proof, so that lecturers can provide feedback to develop it. In the qualitative stage, the characteristics of the ability of several students are produced. these characteristics are reviewed based on student responses to the problem of proof. In the Moore method of learning, students are not allowed to open teaching materials, so the lecturer must follow the flow of student thinking and direct the thinking process. As an implication of the results of this study, the Moore method is well used with the notes that students must study before learning in class.
