ANALISIS : KESULITAN SISWA DALAM MEMAHAMI SISTEM ORGAN MANUSIA DAN IMPLIKASINYA TERHADAP PEMBELAJARAN IPA
Get PDFEducation is a fundamental process in the development of individuals and society. Through education, knowledge, skills, values, and attitudes are transferred from one generation to the next, enabling intellectual, social, and emotional development. The purpose of this study was to determine the problems related to materials that are considered difficult and how to solve these learning problems in science learning in elementary schools. This research method uses a mix-method research type where quantitative data is reinforced with qualitative data. This study involved two science teachers and 25 fourth-grade elementary school students. The instruments used included questionnaires, interview sheets, and observation sheets. Data were collected by going directly to the field and analyzed using descriptive analysis for quantitative data and analysis of interview results for qualitative data. The results showed that there were two materials that were considered difficult by fourth-grade elementary school students, namely the Human Organ System (40%) and Photosynthesis (36%). The solutions used for the Human Organ System material usually use learning video media and e-learning platforms as supporting media. Meanwhile, for the Photosynthesis material, the solution provided was the use of practical demonstration tools and a digital microscope. The conclusion of this study is that video learning media, e-learning platforms, practical demonstration tools, and digital microscopes can be alternative solutions in helping students understand material that is considered difficult
Sink position analysis of energy efficiency in Wireless Sensor Network (WSN) using routing Stable Election Protocol (SEP)
Get PDFWireless Sensor Network (WSN) is a wireless network that involves sensors in the network. The sensor node on the WSN will collect data information from the environment around the sensor. However, each sensor node has storage capacity, processing power, communication range, and battery life limitations. The use of energy consumption from these factors is the main problem because each sensor node uses its power consumption from the battery. Stable Election Protocol (SEP) is a type of routing protocol on WSN that uses the clustering method. SEP has a function to extend the time interval before the first node dies. This research was carried out on the SEP protocol with alive node parameters, total initial energy, and stability. This study indicates that on a network that uses 100 nodes with sink positions (0, 100), two nodes are still alive and several nodes that are still alive in several sink positions that use 200 nodes. For networks where there is still a lot of energy remaining in the sink position (0, 100) with the network using 100 nodes and for networks using 200 nodes, the remaining energy is mainly in the sink position (100, 100). The highest stability period is in the sink position (50, 50) for networks using 100 nodes, and for networks using 200 nodes, the highest stability period is in the sink position (100, 50)
PENGARUH PRODUK DOMESTIK BRUTO (PDB), INFLASI DAN KURS RUPIAH TERHADAP YIELD SUKUK NEGARA SR 009 PERIODE 2017-2020
Get PDFThe sale and purchase of Islamic bonds or sukuk products in the secondary market is more volatile, the profit which is the reference for investors in the secondary market is generally yield to maturity (YTM) or often called yield. According to Laily Fitriyah et al. in their research, the economic conditions in a country can be an important reference for investors\u27 decisions in that country, this is in line with the theory pioneered by Rosel in 1963, namely the Arbitrage Pricing Theory that bond yields can be influenced by macroeconomic factors. Gross Domestic Product (GDP), inflation and the rupiah exchange rate are some branches of macroeconomics that can describe the economic condition of a country. This study uses the Vector Error Correction Model (VECM) data analysis method. The data processing tools used are Eviews9 and Microsoft Excel 2019 to support initial data processing. The VECM estimation results show that in the short term only the rupiah exchange rate variable has a significant negative effect on the yield of SR09, GDP has an insignificant negative effect and inflation has an insignificant positive effect on the yield of SR009. Meanwhile, in the long term, all independent variables have a significant negative effect on the yield of SR009.Keywords: GDP, Inflation, Rupiah Exchange, Yield
PERANCANGAN SISTEM MONITORING BERAT AYAM BERBASIS PROTOKOL MQTT
Get PDFTerbatasnya teknologi yang dapat memantau perkembangan berat ayam setiap saat menjadi salah satu alasan peternak harus menimbang ayam secara rutin. Pengecekan setiap saat membutuhkan banyak input produksi berupa tenaga manusia. Sedangkan ayam broiler rentan mengalami stress jika sering ditimbang beratnya. Oleh karena itu penulis memilih perangkat monitoring berat ayam untuk memantau informasi berat ayam secara jarak jauh melalui sebuah web. Pada kandang ayam dihubungkan dengan sensor loadcell sebagai sistem untuk membaca dan mengambil data berat objek dari lingkungan sekitar serta untuk sistem kontrolnya menggunakan mikrokontroller NodeMCU dengan ESP8266 sebagai media transmisi nirkabel pada perangkat I/O. Data yang telah diambil oleh sensor loadcell akan diproses oleh mikrokontroller NodeMCU ESP8266 yang kemudian dikirimkan ke sebuah server. Terdapat satu protokol yang dianalisa yaitu protokol Message Queuing Telemetry Transport (MQTT). Penelitian mencakup analisa Quality of Service (QoS) pada objek di protokol dan menganalisa pengiriman data pada protokol MQTT. Beberapa parameter Quality of Service (QoS) yang digunakan sebagai acuan penelitian adalah Delay, Jitter, Packet Loss dan Throughput. Hasil pengujian pada penelitian ini menunjukan bahwa alat monitoring yang diuji pada ayam berbobot rata-rata 1.97 kg memiliki nilai keakuratan sebesar 99,7%. Serta protokol MQTT pada parameter delay memiliki kualitas layanan sangat baik pada rentang 107.101 – 129.544 ms. Sementara kategori jitter memiliki kualitas yang baik pada rentang 0.002 – 0.052, parameter throughput memiliki nilai rata-rata 29557.172 - 31401.873 bps dan parameter packet loss memiliki kualitas layanan yang sangat baik yakni hanya sebesar 0.0001% – 0.0008%. Hasil pengujian tersebut menunjukkan bahwa penggunaan protokol MQTT baik digunakan pada perangkat monitoring berat ayam broiler
Electrode engineering in memristors development for non-/erasable storage, random number generator, and synaptic applications
No full textWe report the process development of ZnO-based memristors and observe various switching phenomena by means of electrode engineering, such as digital-to-analogue transformation, irregular and uniform endurance, and non-erasable switching; we also discuss the potential applications for each of these switching phenomena. The use of inert electrodes induces a high injection of electrons into the switching layer triggering abrupt current changes and, in some cases, resulting in a device breakdown. Meanwhile, a low work function and oxidizable electrode encourage Ohmic contact at the oxide/electrode junction and exhibit gradual switching characteristics. This work addresses the importance of electrode configuration to achieve the desired switching behaviour for specific low-powered electronic applications
