Bimbingan Teknis Penulisan Soal HOTS Bagi Pendidik di SDK 086 Nangahaledoi

Kegiatan Pengabdian Masyarakat ini bertujuan untuk meningkatkan keterampilan para pendidik di SDK 086 Nangahaledoi terkait teknik penyusunan soal yang memenuhi kriteria High Older Thinking Skill (HOTS). Kegiatan ini didasari pada masih rendahnya kompetensi pendidik yang dikeluhkan sehubungan dengan cara menyusun soal yang berkategori HOTS. Kegiatan ini diadakan pada tanggal 16 dan 17 November 2020 bertempat di SDK 086 Nangahaledoi Kecamatan Waigete Kabupaten Sikka. Metode pelaksanaan PKM ini adalah kaji tindak partisipasif. Metode ini berarti pengikutsertaan seseorang untuk melakukan sesuatu atau pengambilan bagian dari sesuatu yang harus dilakukan oleh pelakunya. Jadi, peserta terlibat secara aktif dalam kegiatan penyusunan soal HOTS. Hasil dari kegiatan ini dapat meningkatkan kompetensi pendidik dalam menyusun soal HOTS yakni semua peserta didik dapat mengembangkan materi dari KD, merumuskan indikator sesuai level kognitif, dan menulis butir soal sesuai indikator soal

Offshore Stratigraphic Architecture of the Miocene to Actual Deposits in the Southern Margin of Rio-Del-Rey (South Cameroon)

The study of the geometric deposits in a basin allows the reconstitution of its tectonic and eustatic history. The Rio-del Rey basin, upon which this study is being carried out, constitutes one of the two Cameroon margin basins located North of the Cameroon volcanic line. To study the stratigraphic architecture of the Miocene deposits consists in characterizing the deposits geometry by discriminating the controlling factors. This study is based on data, made up of 13 seismic lines and 07 wells and then on various methods related on seismostratigraphy and diagraphies. The obtained lithologies in the study area constituted essentially of sandy and clayey deposits from Paleocene to Recent. They are grouped differently in to Akata, Agbada and Benin Formations, and the Isongo Member. These deposits are set up in marines (bathyal and neritic), deltaics, turbiditic cones slope and fluvial channels environments. Three second-orders sequences were identified (S1, S2 and S3), they are made up of deposits presenting variable geometries along the basin. They are prograding, aggrading, in domes and synclinal. The disposition of the deposits was influenced by tectonic structures such as folds and faults. The isochronal map allows understand the sedimentary flow impact on topographic evolution of the basin in the upper- Miocene. It turns out that, deposits of this basin present various geometric tectonics control (subsidence and uplift) that constitute a major influential factor, being marked by the presence of synclines (gravity tectonics), domes (argilocinesis) and syn-sedimentary faults. The fall in marine level eustatism gives rise to progradations, whereas, a rise in marine level is responsible for retrogradations and aggradations. Thus, the sedimentary flow exerts a secondary control. It is related to the above two major factors

Bidirectional push–pull/H‐bridge converter for low‐voltage energy storage system

Abstract A bidirectional push–pull/H‐bridge DC/DC converter for a low‐voltage energy storage system is proposed in this paper. It comprises the push–pull converter, the phase‐shifted H‐bridge converter, and the transformer. The push–pull converter is connected to the low‐voltage side, and it is controlled by 0.5 fixed duty ratio. The phase‐shifted H‐bridge converter is connected to the high‐voltage side, and it is controlled by an extended phase shift scheme with zero voltage switching (ZVS). Compared with the conventional dual active bridge (DAB) DC/DC converter, the proposed converter has a simple structure—there are only two power switches with a common ground and simple gate‐driving circuits in the low‐voltage side. The 600‐W laboratory prototype was developed to confirm the theoretical analysis and the validity of the proposed converter

Highly Efficient Single-Stage DAB Microinverter Using a Novel Modulation Strategy to Minimize Reactive Power

This article proposes a highly efficient single-stage dual-active-bridge (DAB) microinverter with a novel modulation strategy to minimize the reactive power flow of DAB converter. Using the proposed modulation, the DAB microinverter achieves good controllability and high efficiency with the following features. First, the variable-frequency control algorithm linearizes the nonlinear function of the phase shift angle, enabling a simple closed-loop control for the sinusoidal trajectory tracking. Second, the proposed modulation strategy minimizes the reactive power flow during the switching period while guaranteeing the zero-voltage-switching (ZVS) turn-on of all switches. With minimized reactive power, current stress and power losses are significantly reduced. Thus, the DAB microinverter achieves a maximum efficiency of 96.87%. Third, the proposed phase shift angles and switching frequency are obtained in an analytic form, thereby that they are computationally simple and easy to implement. The operation principle of the proposed modulation strategy is theoretically analyzed and verified. Experimental results based on a 330-W prototype module are conducted to evaluate the performance of the proposed inverter and to verify the analysis.11Nsciescopu

Characterisation of different parts from

Fatty acids, amino acids, as well as total phenolic content and antioxidant activities, were presented from Moringa oleifera different parts (whole seeds, kernels, coats, pods and leaves). The investigated parts were a good source of protein (29.2, 37.8, 11.9, 10.1 and 22.8 g/100 g for whole seeds, kernels, coats, pods and leaves, respectively) with isoleucine, leucine, arginine, glycine, glutamine and tyrosine as amino acids in sufficient amount to meet the nutritional needs. Moringa seeds are also rich in oil. Oleic acid was the most abundant fatty acid in moringa seeds (66.2 and 65.8% for whole seeds and kernels, respectively). Leaves were rich in minerals such as P, K, Mg and Fe with the highest amount of total phenolic content. 70% ethanol, 80% methanol or water showed the highest yield with of total phenolic content from leaves reaching 11.8, 11.3 and 8.9 mg GAE/g, respectively. The lowest ED50 values were reported for extracts of leaves obtained by 70% ethanol and 80% methanol (0.51 and 0.54 mg), respectively, indicating more antioxidant activity than for the other solvents. For the ß-carotene-linoleic acid assay, leaves extract showed also the strongest effect for delaying the oxidation followed by extracts from pods and coats in a comparison with the control without antioxidants. From this comprehensive investigation of the different parts of MO, an assessment of the raw materials regarding their application as food is possible

Oxidative stability of

Enhancement of the oxidative stability of cactus seeds oil by blending with moringa seeds oil was investigated during storage period for four weeks at 50 °C. Blends (25, 50 and 75%) of moringa seeds oil with cactus seeds oil were prepared. Fatty acids composition, induction period, peroxide value, specific extinction coefficients (K232 and K270) and tocopherols were studied. Blending moringa seeds oil with cactus seeds oil at 25:75% increases the induction period to 4.06 h while it was 3.16 h in 100% cactus seeds oil. Peroxide values decreased due to increase moringa seeds oil amount in blends. Also, adding moringa seeds oil to cactus seeds oil caused a decrease in K232 and K270 values during the storage period in comparison with 100% cactus seeds oil. α-tocopherol values decreased during storage for all oil blends, while the content of γ-tocopherol in all samples (except moringa seeds oil) increased during storage period reaching the highest level after the third week then it started to decrease. Therefore, the obtained results provided a potential approach to utilize moringa oil to increase the oxidative stability of edible oils
