2020 Luteinizing Hormone Receptor Gene Polymorphism of Pasundan Cattle in Ciamis DN Arifin, C Sumantri, DN Hadi. Pasundan cattle is a local livestock that has lived and well adapted in West Java. In 2015, the population declined by 20.96% caused by the high selling prices and changes in land functions. The impact of declining of the population can causes genetic degradation indirectly. One of the efforts to increase the population is selection of cattle based on luteinizing hormone receptor gene polymorphism that can used as molecular selection for reproductive traits. Thirty seven heads of Pasundan cattle with artificial insemination calving records was used in this study. The exon 11 of LHR gene was amplified and subsequently analysed… Lihat
2020 13.56 MHz Scalable Shielded Capacitive Power Transfer for Electric Vehicle Wireless Charging Suziana Ahmad, Reiji Hattori This paper proposes a scalable shielded capacitive power transfer (S-CPT) for mini electric vehicle (EV) wireless charging application. The design and analytical studies of the proposed S-CPT are introduced by using LTSpiceTM simulation software. In order to obtain an accurate calculation of the impedance matching network, the capacitances appeared in the system are observed with finite element analysis (FEA) tools using ElecNetTM software from InfolyticaTM. With a 3-cm shield-shield gap, 3.46 pF of coupling capacitance and 10.9 pF of shield coupling capacitance are acquired by FEA. A Spice simulation result shows as high as 97% efficiency provided by the proposed… Lihat
2020 MENENGAHI KEBUNTUAN PENGELOLAN DANAU MANINJAU: METODE NEGOTIATED APPROACH (NA) SEBAGAI ALTERNATIF Tantangan terbesar dari pengelolaan sumber daya bersama adalah bagaimana mengkoordinasikan pemanfaatan oleh setiap individu, terutama saat pertumbuhan penduduk men- imbulkan tekanan baru terhadap sumber daya tersebut. Selain itu, hal yang tidak kalah pentingnya adalah bagaimana tata kelola juga melibatkan kedua belah pihak, masyarakat dan pemerintah. Pada saat yang sama, definisi sumber daya bersama dan lemahnya tata kelola cenderung menyebabkan kerusakan dan penurunan kualitas sumber daya dan konflik (Islam & Suskind, 2013). Bab ini akan menelaah bagaimana pendekatan pendekatan negosiasi inklusif dapat digunakan sebagai alternatif pengelolaan Danau Maninjau. Lihat
2020 Toward Improvement of Cloud Computing Scheduling Algorithms to Monetary Cost and Makespan Time Efficiency Fang-Yie Leu Cloud computing is distributed computing that offers dynamic, scalability and pay-per-use. The main purpose of cloud computing are the ease of access from any location and the management of practical computing resources. One of the challenges faced by cloud technology today is scheduling. The role of scheduling algorithms is very important, since it executed the task by ordered that may need a more attentions. Here, scheduling algorithms intended to minimize monetary cost and minimize makespan time to execute the workflow. The Most popular of scheduling algorithms deal with currently designed for traditional environments and not applicable for cloud environments. This… Lihat
2020 APLIKASI PENCIRI MOLEKULER UTY DAN SRY UNTUK DETERMINASI UNKNOWN SEX SAMPLES PADA SAPI BALI Endang Tri Margawati,Slamet Diah Volkandari,Indriawati An investigation involving large number of animals is often resulting incomplete or in accurate information such as animal parentage, or misidentify on sex due to unlabeled sex samples. A PCR method by applying Y chromosome markers (UTY and SRY) facilitates in determination of unknown sex problem. This study was intended to determine sex from unlabelled sex of blood samples by applying PCR method using a pooled-DNA template. Twenty five of unknown sex blood samples from Nusa Penida, Bali were used in this study. The samples were plotted into 5 pooled-DNA whith each pool DNA consisted of 5 individuals DNA. Two… Lihat
2020 Micro-structures and magnetic properties of Mg-Al substituted in barium hexa-ferrite prepared by co-precipitation method Martha Rianna, Timbangen Sembiring, Marhaposan Situmorang In this study, Mg-Al substituted barium hexa-ferrite of BaFe 12- 2x Mg x Al x O 19 (x=0-0.2) materials using co-precipitation method at a calcination temperature of 1200 o C for 2 hours were carried out. The precursor concentrations of the mixture were varied to identify the optimum sample. The final powder was characterized by using XRD, FE-SEM, and VSM. The XRD shows that the Mg-Al substitution was not change the micro-structures of barium hexa-ferrite. FE-SEM observation was carried out on the surface of hexagonal shape of barium hexa-ferrite. The magnetic properties shows that the decreases saturation (Ms), remanence (Mr)… Lihat
2020 Diversity of endophytic fungi from Vernonia amygdalina, their phenolic and flavonoid contents and bioactivities Praptiwi,Muhammad Ilyas,Ahmad Fathoni Praptiwi, Fathoni A, Ilyas M. 2020. Diversity of endophytic fungi from Vernonia amygdalina, their phenolic and flavonoid contents and bioactivities. Biodiversitas 21: 436-441. There are nine endophytic fungi in total associated with stem and leaves of Vernonia amygdalina were determined for their total phenolic and flavonoids content as well as assessed for their antibacterial and antioxidant activities. Total phenolic and flavonoid contents were determined by spectrophotometric methods. The antibacterial activity was performed using Thin Layer Chromatography (TLC)-Bioautography assay against S.aureus and E.coli. The antioxidant activity was carried out using TLC-Bioautography by DPPH scavenging assay. Broth serial microdilution assay was used… Lihat
2020 Plant Materials Transferred Management: A part of ex-situ conservation business process of Cibodas Botanic Gardens Imawan W. Hidayat, Yudi Suhendri One of the botanic gardens businesses is socializing cultivated plants from the garden to be further utilized, especially for reforestation (and other conservation purposes), research and educational purposes. This socialization can be conducted through seeds exchange and plant (and parts) that transferred for various users. Cibodas Botanic Gardens (CBG), as one of the Indonesian botanic gardens, is also conducted this activity. Plant materials and so the data needed for these purposes are recorded in the material(s) transfer agreement (MTA). The study aimed to analyze the number, type, and species of transferred plant materials and the data, the background of the… Lihat
2020 Effect of Co and Ni additions as doping materials on the micro-structures and the magnetic properties of barium hexa-ferrites Masno Ginting, Perdamean Sebayang , Martha Rianna, Marhaposan Situmorang, Heryani Fujiati, Anggito P. Tetuko, Eko Arief Setiadi, Candra Kurniawan, Achmad Maulana Soehada Sebayang In this paper, the synthesis of BaFe12-2xCoxNixO19 (x ¼ 0–0.2) materials at a calcination temperature of 950 �C using a co-precipitation method have been reported. The precursor concentrations of the mixture were varied to identify the optimum sample. The results suggested that the structure of barium hexa-ferrite crystal did not change due to the effect of Co and Ni additions. The optimum condition is obtained at the concentration of 0.2% mol of Co and Ni ions resulting a single phase of barium hexa-ferrite. The XRD analysis confrmed that the addition of Co and Ni affects the growth of barium hexa-ferrite… Lihat
2020 Paten Granted: Aditif Organik Pemacu Pertumbuhan Dan Imunitas Ternak Unggas Serta Proses Pembuatannya Lusty Istiqomah, Septi Nur Hayati, Ema Damayanti, Hardi Julendra, Mohammad Faiz Karimy, Awistaros Angger Sakti, Ahmad Sofyan, Hendra Herdian, Ade Erma Suryani Abstrak: Konsumsi daging sebagai sumber protein hewani di Indonesia (±4,5 kg/kapita/tahun) masih jauh dibandingkan dengan negara-negara lain khususnya di ASEAN seperti Malaysia (±38,5 kg/kapita/tahun) atau Singapura (±48 kg/kapita/tahun). Salah satu faktor penyebabnya yaitu rendahnya produksi daging ungags (1,5 juta ton/tahun) yang disebabkan masalah penyakit. Penyakit yang biasa muncul dan menjadi perhatian serius di industry perunggasan yaitu penyakit saluran kencernaan (intestinal disease), karena selain menimbulkan kerugian ekonomi juga berdampak buruk pada manusia sebagai konsumen. Penggunaan probiotik khususnya bakteri asam laktat sebagai imbuhan pakan (feed additive) merupakan salah satu cara untuk mengatasi penyakit saluran pencernaan serta meningkatkan performa dan kesehatan ternak.
