Dona Astari Nurkarimah, Ekayanti Mulyawati Kaiin, Ni Wayan Kurniani Karja, and Mohamad Agus Setiadi |
The purpose of this study was to evaluate the effectiveness of cysteamine supplementation on the maturation medium and/or in vitro fertilization medium with regards to improving the normal fertilization rate of sheep oocytes, which are characterized by the formation of two pronuclei. Grade A and B oocytes were matured in medium-199 with 0.3% bovine serum albumin (BSA), 10 IU/mL follicle stimulating hormone (FSH), 10 IU/mL human chorionic gonadotrophin (hCG), and 50 μg/mL gentamicin added for 24 hours in a 5% CO2 incubator at 39° C. The treatment group was divided into the following groups: a control group with no cysteamine… |

Two-Dimensional Nuclear Magnetic Resonance Analysis of Hydrogen-Bond Formation in Thermosetting Crystalline Urea–Formaldehyde Resins at a Low Molar Ratio |
Nanang Masruchin,Eko Setio Wibowo,Byung-Dae Park |
The unique phenomenon of crystalline domain formation in thermosetting crystalline urea–formaldehyde (UF) resins at low formaldehyde-to-urea (F/U) molar ratios is responsible for their poor adhesion as wood adhesives. The crystalline domains are apparently formed by hydrogen bonds between linear molecules in UF resins at low molar ratios. Clear evidence for the formation of linear molecules and subsequent hydrogen bonds in the UF resins using two-dimensional nuclear magnetic resonance (2D NMR) spectroscopy is reported for the first time through our study. One-dimensional and 2D NMR spectroscopies were used to compare the short-range and long-range correlations between hydrogen, carbon, and nitrogen atoms… |

Can’t we negotiate the importance of electron correlation? HF vs RIMP2 in ab initio quantum mechanical charge field molecular dynamics simulations of Cu+ in pure liquid ammonia |
Wahyu Dita Saputri,Harno Dwi Pranowo, Thomas S.Hofer |
The impact of electron correlation in quantum mechanical charge field molecular dynamics (QMCF MD) simulations of Cu+ in pure liquid ammonia has been investigated by comparing the results obtained at the Hartree–Fock (HF) level and via resolution-of-identity second order Møller–Plesset perturbation theory (RIMP2). To achieve a manageable computational demand, a rigid-body solvent model was employed to describe the NH3 molecules. The solvation structures observed in both cases have similar characteristics in which tetrahedral [Cu(NH3)4]+ dominates with average Cusingle bondN distances of 2.24 (HF) and 2.12 (RIMP2) Å, respectively. The ligand dynamics in the first solvation shell of the RIMP2 simulation… |

Impact of Local REDD+ Intervention on Greenhouse Gas Emissions in East Kalimantan Province, Indonesia |
Martiwi Diah Setiawati,Kiswanto, Satoshi Tsuyuki |
The Ministry of Environment and Forestry (MoEF) of the Republic of Indonesia selected East Kalimantan as a pilot area for trialing a national REDD+ program under Forest Carbon Partnership Facility (FCPF). If it works, this pilot area will receive the payment of forest carbon services. Thus, East Kalimantan provincial government established the Green East Kalimantan strategy in 2010 to improve the natural resources and Green Growth Compact in 2016 to reduce carbon emission and increase economic growth by 8%. This paper estimated greenhouse gas (GHG) emissions before and after the REDD+ commitment implemented in the study area. The annual land… |

KEBIJAKAN KESEHATAN: UPAYA PENANGGULANGAN PENYAKIT MALARIADI REPUBLIK TANZANIA |
Dhani Saptia Hudaya,Yogi Suprayogi Sugandi |
One of the diseases that threatens the lives of people in the world is malaria. The Republic of Tanzania is one of the
countries that has a malaria problem that causes many deaths. However, health policies in dealing with malaria
are problematic. This research uses descriptive qualitative research methods. Data obtained using secondary
data with literature studies. The results of the analysis show that the limitations and inability of the government in
allocating the budget to provide adequate medical personnel, medicines, and health facilities. On the other hand,
the Tanzania’s government efforts to prevent malaria are still constrained by the… |

Real-Time FPGA Implementation of FIR Filter Using OpenCL Design |
Yoshiki Yamaguchi |
This paper proposes the implementation of a real-time finite impulse response (FIR) filter with a field-programmable gate array (FPGA) and Open Computing Language (OpenCL) designed by directly streaming the input signal. OpenCL is selected for its high productivity to reduce the time of development. It also has a high-level abstraction of the code to avoid users from writing the HDL code, platform-specific tools, and their libraries. Moreover, it is a C-based programming language for parallel programming which is especially employed in high-performance computing. However, OpenCL for FPGA does not give access to directly read/write signals to the FPGA I/O pins.… |

Adaptation strategy to coastal erosion by rural communities: Lessons learned from Ujunggebang village, Indramayu, West Java, Indonesia |
Wahyu Budi Setyawan |
Coastal hazard due to wave activity, in the form of coastal erosion, has long been a problem in the coastal area of Ujunggebang. Loss of coastal land in the coastal area has removed a lot of rice fields, settlements, and public facilities. Efforts to maintain the coastline along 3,300 m of the coastal area, by building coastal defense structures (CDS), have been carried out by the central government since 2006 but, until 2015, the CDS that has been built is still only around 1782 m long, in some places the structure is damaged due to wave activity, and in general… |

Analysis of GHG emissions of tofu industry, study case in Indonesia |
|
Tofu is one of the protein sources with high demand in Indonesia. Currently, several tofu industries have used stainless steel-based equipment. This condition shows the seriousness of the tofu industry to make hygienic tofu products. However, hygienic tofu products are not enough. The competition of global market required the products to take notice not only for its quality, but also come into environmentally-friendly product that characterized by low value of CO2 emission. In accordance to the condition, studies related to the calculation of CO2 emissions resulted from a product are necessary. In this study, we conducted research on the estimation… |

Discovery of a genetically distinct lineage in medaka species within Lake Towuti in central Sulawesi |
|
Oryzias marmoratus and Oryzias profundicola in Lake Towuti in Sulawesi are considered to have experienced ancient admixture with a lineage phylogenetically close to the extant O. marmoratus in Lake Lantoa. However, the admixture may be ongoing because these lakes are currently connected to each other by rivers. In this study, we examined population genetic structures of O. marmoratus and O. profundicola in Lake Towuti and adjacent lakes. Mitochondrial and microsatellite analy- ses revealed that O. marmoratus and O. profundicola in Lake Towuti are generally clearly separated from O. marmoratus in Lake Lantoa. However, we found one O. marmoratus individual in… |

Gumilar Utamas Nugraha,Rachmat Fajar Lubis,Hendra Bakti,Andi Agus Nur (UNPAD), Pulung Arya Pranantya (PUPR) |
Pangkalpinang city is the capital of the Bangka Belitung Islands Province, Indonesia. With the increase in population and the economy in the Pangkalpinang city, water resources' need also increases. This study aimed to analyze potential groundwater areas to ensure the availability of water for this city using Dar-Zarrouk Parameters. Vertical Electrical Sounding (VES) measurements have been conducted at eight points around the city of Pangkalpinang using the Schlumberger array configuration. Dar-Zarrouk parameter was calculated using two parameters of the geoelectric inversion results, i.e., resistivity and layer thickness. The IPI2Win inversion results show that the resistivity value ranges from 96 to… |
