Abstract

Photovoltaic merupakan sumber energi terbarukan dengan beberapa keuntungan tetapi keluaran dari photovoltaic masih berupa sumber listrik DC sehingga penggunaannya terbatas. Maka dari itu diperlukan suatu alat yang bisa mengkonversi tegangan DC ke tegangan AC sehingga sumber photovoltaic bisa digunakan untuk menyuplai beban yang bervariasi dan dimanfaatkaan untuk menyuplai beban rumah tangga. Inverter push-pull merupakan salah satu jenis inverter yang paling sering digunakan karena hanya membutuhkan input tegangan DC kecil dengan keluaran tegangan AC yang sesuai dengan beban AC rumah tangga (220V). Penggunaan rangkaian resonan paralel untuk memperbaiki bentuk gelombang keluaran inverter karena menggunakan rangkaian kontrol IC SG3524 yang merupakan kontrol PWM analog. Penelitian ini menggunakan beban resistif dan beban dinamis untuk melihat pengaruh variasi duty cycle dan variasi frekuensi terhadap tegangan output, kecepatan putar motor, serta efisiensi dari inverter. Efisiensi inverter push-pull resonan paralel ketika beban resistif 37,3 Ω dengan range dari 24%-62%. Efisiensi inverter push-pull resonan paralel ketika beban resistif 333 Ω dengan range dari 26%-35%. Efisiensi inverter push-pull resonan paralel beban dinamis berupa motor AC shaded pole dengan range dari 26%-43%. Efisiensi inverter push-pull resonan paralel beban motor universal dengan range dari 27%-54%. Efisiensi inverter push-pull resonan paralel beban motor induksi run capacitor dengan range dari 25%-49%.

Abstract

 This article aims to describe the process of making and effective methods for the dissemination of decision results in the Industrial Revolution 4.0 era. This research uses library research taken from scientific journals and relevant literature. The results showed that the most effective decision making process was a combination of top-down and bottomup with formal decision-making mechanisms or decisions. Decision making formally involves leaders and subordinates and adjusted to the output of the meeting. The dominant dissemination mechanism is traditional dissemination through meetings and through social networks. The implications of the results of this study indicate that the formal process of decision making through public meetings or limited meetings is still the choice of the decision making process so that this traditional model provides space for all elements involved to participate and provide constructive advice for effective decision making.

Abstract: Penelitian jamur Makrokopis di Cagar Alam Timur pulau Nusakambangan bertujuan untuk mengetahui keanekaragaman jenis jamur makroskopis. Metode yang digunakan dalam pengambilan data adalah metode jelajah dengan melakukan pengamatan langsung pada area CA Timur Nusakambangan (Pesisir pantai, Hutan dan DAS) . Melihat kondisi hutan di Cagar Alam Timur Nusakambangan yang masih bagus serta pepohonan masih rapat melindungi lantai hutan dan kondisi sungai juga masih bagus dengan masih terlindungi oleh beberapa pepohonan hal ini memungkinkan banyak terdapat Jamur Makroskopis. Hasil dari penjelajahan dan pendataan didapat 17 spesies teridentifikasi Maramius androcaseus, Tremella fuciformis, Rigidoporus microsporus, Ganoderma sp, Ganoderma lucidium. Ganoderma appalantum Cookeina sulcipes, Microporus xanthopus, Lichenomphalia umbullifera, Gyromitra infula, Auricularia ploytricha, Auricularia auricula-judae, Lentinus sajor-cajor, Rigidoporus sp., Tricholoma crassum., Scleroderma sinnamariense., Leucocoprinus sp. dari 11 famili hal ini menunjukan bahwa keanekaragaman jenis jamur makroskopis di Cagar Alam Timur pulau Nusakambangan sangat beragam.

Abstract

This study examines the development of the Qur'anic Study Paradigm, by knowing this development, one has a broad view and avoids radical and extreme attitudes. In addition, an anti-violence attitude in responding to differences, contextualization in understanding religious texts. This study uses a qualitative approach with the type of research library research, where researchers utilize various sources both primary and secondary contained in various journals, books and research results. Furthermore, data analysis was carried out. The development of interpretation from classical to contemporary cannot be separated from the historical roots where the Qur'an was understood by the early generations of Islam. In the classical era there were at least two stages in the study of the Qur'an, namely formative with Quasi-Critical reasoning or paradigms and affirmative with ideological reasoning. Post-Orientalism, criticism of the Qur'an became a prominent theme in the West. This phase is called transformative. This stage is called the reformative era with critical reasoning. Existing interpretation products are not taken for granted as 'truth'. However, they have begun to be criticized and questioned, while transformative means that interpretation is built to transform the people and to answer and solve real problems that are emerging and developing in society.

Abstract

Salah satu dampak saat pandemi adalah pendidikan. Bagaimana pembelajaran tetap berlangsung walaupun dalam masa pandemi Covid-19. Namun, banyak wali murid yang merasa bahwa pembelajaran daring jika diterapkan pada anak usia dini dirasa kurang maksimal. Penelitian ini menerapkan pendekatan fenomenal deskriptif dengan teknik wawancara dan obervasi. Instrumen pertanyaan wawancara berisikan 30 pertanyaan, dengan narasumber kepala sekolah dan 7 guru kelas yang ada di TK Unggulan An-Nur Surabaya. Hasil penelitian ini adalah Di TK Unggulan An-Nur Surabaya menerapkan pembelajaran daring maupun luring. Bimbingan dan konseling tetap diterapkan sebagaimana sebelum pandemi. Saat pembelajaran melalui daring, wali murid dapat berkonsultasi pribadi dengan guru kelas. Kegiatan home visit yang dilakukan adalah sebagai bentuk observasi yang dilakukan oleh sekolah ke rumah wali murid dengan tujuan mengobservasi bagaimana latar belakang peserta didik dan lingkungannya.

Abstract

Education is the right of everyone to get the opportunity to develop their potential through a process called learning which is said to be able to break the chain of poverty. However, has the implementation of this statement been running properly in Indonesia? That every citizen has the same rights in the form of the opportunity to attend school to university? Is "Education for All" just an empty program? The basic concept of equal opportunity to receive education which is focused on equality in education and equity in education seems to have not worked out ideally or even hindered each other. Discrimination of society on the basis of status and class to obtain privileges in obtaining educational opportunities is also still the biggest enemy for the basis of education for all. All kinds of arguments were expressed, ranging from government regulations that change frequently, low public awareness of the importance of education, the education ladder that feels the need to sacrifice a lot of money, and free education policies that sometimes do not match the reality and expectations of the community. By going through the library research method, this journal will more or less discuss how the principle of free education is often found contradicting the practice of educational capitalism which is so rampantly multiplying in the middle of the 4.0 era which actually requires the younger generation from the lower classes to the upper classes to continue to develop and continue to explore their potential through education.
