The emerging trend technologies imply the increase in the new role of the future of jobs. Most of them required Computer Science-related skills a lot, especially programming. However, there is a skill gap for it. Some previous studies showed that many students feel difficulties in learning programming. In the last decades, there are many approaches to improve student’s learning achievement through active learning methods. One of those approaches is the Flipped Classroom (FC) method. This study presents a systematic literature review of the FC approach in the programming course. The aim of this study is to explore the strategy of FC implementation in the programming class. A total of 32 papers from ACM Digital Library and IEEE Xplore Digital Library are selected for this review. We found four types of implementation of FC in programming, with the variations of the in-class or out-class activities.

Abstrak. Tujuan penelitian ini adalah 1) mengetahui pelaksanaan konseling teman sebaya, 2) mengetahui keefektifan konseling teman sebaya meningkatkan keterampilan interpersonal siswa. Metode penelitian ini adalah penelitian tindakan bimbingan dan konseling. Subjek uji coba terbatas terdiri dari 34 siswa. Hasil penelitian menunjukkan bahwa konseling teman sebaya dapat meningkatkan keterampilan interpersonal melalui 4 tahapan yang lazim dilalui yaitu: (1) Perencanaan, (2) Pelaksanaan, (3) Pengamatan, dan (4) Refleksi. Berdasarkan hasil penelitian menunjukkan terdapat peningkatan skor rata-rata pre test 963 dan pada saat post test 1.084 atau meningkat 121 poin. Sehingga konseling teman sebaya meningkatkan keterampilan interpersonal siswa terbukti efektif. Guru bimbingan dan konseling disarankan dapat menerapkan konseling teman sebaya secara kontinyu dan bekerja sama dalam melakukan pembinaan dan pendampingan dalam meningkatkan kompetensi konselor sebaya.Kata Kunci: Konseling Teman Sebaya; Komunikasi Interpersonal I. PENDAHULUAN Aktivitas yang sering dilakukan dalam kehidupan sehari hari oleh seseorang yakni berkomunikasi dengan orang lain. Komunikasi tersebut dapat terjadi baik dalam lingkungan keluarga, sekolah, maupun masyarakat. Dalam lingkungan keluarga interaksi dapat terjadi antara sesama anggota keluarga, baik orang tua dengan anak maupun sebaliknya. Dalam lingkungan sekolah interaksi dapat terjadi antara sesama warga sekolah yang ada dalam lingkungan sekolah tersebut. Dalam lingkungan masyarakat, interaksi seseorang akan meluas baik dengan teman akrab, teman sepermainan, dan orang dewasa lainnya tergantung sejauh mana individu mampu menempatkan diri.Komunikasi dapat terjadi baik dalam bentuk verbal maupun nonverbal. Dalam bentuk verbal misalnya sekedar bertegur sapa, diskusi, wawancara, debat. Bentuk non verbal dapat berupa gerakan dari anggota tubuh, misalnya mendengarkan, mengangguk tanda setuju, sentuhan. Demikian pula ketika siswa memasuki lingkungan sekolah, ia akan melakukan komunikasi dengan teman-temannya. Komunikasi dalam bentuk verbal dapat dilakukan tegur sapa dengan teman-teman. Sedangkan dalam bentuk non verbal dapat dilakukan dengan merangkul teman atau melambaikan tangan ketika namanya dipanggil oleh temannya.Siswa yang berada pada usia remaja, perlu untuk menjalin hubungan sosial yang baik dengan lingkungannya. Dalam masa remaja hal yang terpenting dan juga tersulit adalah penyesuaian diri dengan meningkatkannya pengaruh kelompok teman sebaya, perubahan dalam perilaku sosial, pengelompokan sosial yang baru, nilai-nilai baru dalam seleksi persahabatan, nilai-nilai baru dalam dukungan dan penolakan sosial, dan nilai-nilai baru dalam seleksi pemimpin [1]. Pada masa ini terdapat tiga proses sosial yang dilalui oleh remaja diantaranya berperilaku dapat diterima secara sosial, memainkan peran dilingkungan sosialnya, memiliki sikap positif terhadap kelompok sosialnya [2].

-Problems in this research is students' difficulty within solving conceptual understanding problems. It is caused by teachers are still using many conventional methods and Discovery Learning model used by teachers is not in accordance with the expected procedure. This research is quasi-experimental in form of non-equivalent control group design. Population in this research is all student of 10 th grade of vocational high School Sinar Husni. Randomly, TKJ 3 X class selected as Experiment class treated by Discovery Learning model and TKJ 1 X class as Control Class is treated by conventional approach. The used instruments consisted of early math skills tests, conceptual understanding skills tests and self-efficacy questionnaires. The instrument is stated to have fulfilled the validity and reliability. Data analysis was performed using Mann Whitney U test, Two Path ANOVA and One Path ANAVA. The results showed that the improvement of conceptual understanding ability and students' Self Efficacy who were given Discovery Learning Model was significantly better compared to the students who were given the conventional approach. In addition, there is a difference in the improvement of ability to understand the concept between high, medium, and low for students who are given Discovery Learning Model, where as there is no difference in students' Self Efficacy improvement.

Virtual Private Networks (VPN) are usually based on IPsec. However, IPsec has not been designed with elasticity in mind, which makes cluster of security gateways hard to manage for providing high Service Level Agreement (SLA). Cluster of SGs must be handled, for example, ISPs use VPNs to secure millions of communications when offloading EndUsers from Radio Access Networks to alternative access networks as WLAN. Additionally, Virtual Private Cloud (VPC) providers also handle thousands of VPN connections when remote EUs access private clouds. This paper describes how to provide Traffic Management (TM) and High Availability (HA) for VPN infrastructures by sharing an IPsec context. TM and HA have been implemented and evaluated over a 2-node cluster. We measured their impact on a real time audio streaming service simulating a phone conversation. We found out that over a 3 minute conversation, the impact on QoS measured with POLQA is less than 3%.

MgB2 superconductor is a superconductor with a critical temperature of around 39K and has the potential to replace Nb3Sn and NbTi as superconducting coils to produce high magnetic fields. In this study, monofilament wires have been made to analyze the doping effect of SiC and Carbon Nanotubes (CNT) in its manufacture using Powder-In-Tube (PIT) method. Stainless Steel (SS-316) tube was used as a tube filled with powders of starting materials of Mg, B, SiC and CNT. A total of 8 samples were prepared with variations in the addition of SiC, and CNT as much as 5, 10, and 15 wt %, and also the variations in the addition of Mg composition by 0 and 10 mol % from normal stoichiometric values. The samples were rolled and sintered at 800°C for 3 hours. The samples then were analyzed using SEM (Scanning Electron Microscopy) to analyze the surface morphology, XRD (X-Ray Diffractometer) to analyze the formed phases and crystal structures, and then resistivity versus temperature using cryogenic systems to analyze their superconductivity properties. Based on the results of the XRD analysis, the MgB2 phase is the major phase in the samples and the SiC doping causes the formation of minor phases of Mg2Si and Fe3C. The addition of SiC causes a decrease in crystalline properties of the MgB2 phase due to reaction with SiC, while the addition of CNT does not cause the formation of a new phase. Based on the results of the analysis of resistance versus temperature, it is seen that the addition of SiC causes a decrease in TC value. While the addition of CNT causes the improvement in the nature of superconductivity, but it also causes the decrease of its TC values.

A new species, Cryptocoryne tirtadinatae, from the Schwaner mountains West Kalimantan, Indonesia is described and illustrated. It differs significantly from all other Cryptocoryne species by the short leathery leaves, with the leaf blades shining green–purple pinkish with green markings on the upper surface, and the short spathe with a reddish limb and red spotted tube opening. The chromosome number 2n = 24, is the first report of this number for the genus.
