Published: April 2018

Sektor pertanian Indonesia seharusnya memperoleh dampak positif dari ASEAN-China Free Trade Agreement (ACFTA). Namun demikian, kinerja sektor pertanian belum menunjukkan peningkatan yang berarti ketika sebagian besar komoditas pertanian telah diturunkan tarifnya melalui tahapan ACFTA. Studi ini meneliti dampak ACFTA terhadap kinerja sektor pertanian Indonesia sebelum dan sesudah ACFTA dengan menggunakan deskriptif analisis. Studi ini juga memprediksi kinerja perekonomian dan kinerja sektor pertanian setelah ACFTA diberlakukan secara penuh menggunakan metode ekonometrik dengan persamaan simultan. Hasil studi ini menunjukkan bahwa kinerja sektor pertanian Indonesia tidak lebih baik dibandingkan dengan sebelum implementasi ACFTA, dan diprediksi akan lebih buruk lagi setelah ACFTA diberlakukan sepenuhnya, akibat dari tingginya tekanan kompetisi dan kekakuan produsen domestik. Peningkatan kualitas infrastruktur domestik, pengembangan riset/teknologi serta penerapan regulasi yang mendukung daya saing merupakan kebijakan yang sangat diperlukan. The ASEAN-China Frade Trade Agreement should positively influence Indonesia’s agricultural sector performance. Unfortunately, the current agricultural sector performance shows no signs of significant increase despite a decrease of tariffs on most agricultural commodities through ACFTA. This study sets out to examine the overall impact of ACFTA on Indonesian agricultural sector performance prior to and after the implementation of ACFTA through descriptive analysis. This study also predicts the overall economic performance and agricultural sector performance after the full implementation of ACFTA by utilizing econometric method with simultaneous equation. This study finds that the agricultural sector performance does not improve after the implementation of ACFTA and it argues further that it will weaken due to high pressure of competition and the rigidity of domestic producers. Quality improve on domestic infrastructure, research and technology development and regulations which enhance competitiveness are high priority policies to support Indonesia’s agricultural sector performance.
KONVERGENSI PENDAPATAN INDONESIA DAN MITRA REGIONAL TRADE AGREEMENT (ASEAN+6): APLIKASI METODE CLUSTER FUZZY
Authors: Muslim Azis 
Published: April 2018

Studi ini mengevaluasi pernyataan bahwa Regional Trade Agreement (RTA) mendorong konvergensi pendapatan. Dengan menggunakan data historis dan menerapkan algoritma fuzzy c-means clustering studi ini menguji konvergensi pendapatan Indonesia dan mitra RTA. Hasil studi menunjukkan bahwa dalam dua dasawarsa sejak tahun 1993, meskipun dengan adanya RTA, Indonesia mengalami pertumbuhan ekonomi, tetapi pendapatan Indonesia tidak konvergen ke arah pendapatan negara maju. Perdagangan perlu dipakai sebagai sarana alih pengetahuan dan teknologi serta peningkatan “kapabilitas sosial” untuk mendukung percepatan pertumbuhan ekonomi. This study evaluates the proposition that Regional Trading Agreements (RTA) endorses convergence of income. Using historical data and fuzzy c-means clustering algorithm, this study analyzes the convergence of Indonesia’s income and RTA partners. The results show that in two decades since 1993, with the presence of RTA, Indonesia has experienced economic growth, yet Indonesia’s income did not converge towards the incomes of developed countries. Trade needs to be utilized as a mean to support knowledge and technology transfer and to increase “social capability” to enhance the acceleration of economic growth.

Published: April 2018

The impact attenuator is a safety component which is used to reduce the effects of frontal crash on driver, which can cause injuries. This article describes the design process of the impact attenuator with lightweight materials to satisfy the required weight reduction targets for Formula SAE racing car. This study is carried out as part of weight reduction studies on Formula SAE racing car. As a first step, the impact-absorbing structures and technical features were compared. In this step, it was decided to use EPP foam material with a density of 100 g/l as basic material to design a lightweight impact attenuator. Also, the design outlines of shape and analysis techniques for impact attenuator was defined in this step. Then, validation process was carried out for virtual model of 100 g/l EPP foam material. Foam material model was validated using referencestudy in literature. After model validation, a new impact attenuator was designed according to Formula SAE rules. It is 10% lighter than the standard model. The results show that selected EPP foam material can be used to design a lightweight impact attenuator for formula SAE race car to satisfy weight reduction requirements successfully.
Structure, Electronic And Vibrational Study of 7-Methyl-2,3-Dihydro-(1,3)Thiazolo(3,2-A) Pyrimidin-5-One by Using Density Functional Theory

Published: April 2018

We have presented molecular structure and vibrational wavenumber assignments of 7-methyl-2,3-dihydro-(1,3)thiazolo(3,2-a)pyrimidin-5-one. Both ab initio Hartree-Fock and density functional theory employing 6-311++G(d,p) basis set have been used for the calculations. The scaled values of the calculated vibrational frequencies were used for assignments on the basis of potential energy distribution. The structure-activity relation has been interpreted by mapping molecular electrostatic potential surface. Electronic properties have been analyzed by using time dependent density functional theory (TD-DFT) for both gaseous and solvent phase. The calculated HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energy values show that the charge transfer occurs within the molecule.

The present investigation was undertaken to study the prevalence of gastrointestinal parasites in Rhesus Macaque and Hanuman Langur at Devghat, Chitwan. Altogether 93 fresh faecal samples were collected from Rhesus Macaque belonging to five troops and Hanuman Langur of two troops. About 10 gm of faecal material was collected in sterile vials with 2.5% potassium dichromate solution. These samples were examined microscopically by faecal concentration methods viz. floatation technique and sedimentation technique. Out of 93 samples, 69 (74.20%) were found positive for at least one parasite. Prevalence of helminth and protozoan parasites was 52.68% and 40.86% respectively. Altogether, 10 species of parasites including seven helminth and three protozoa were identified based on morphological characteristics of their eggs and cysts under light microscopy. The most commonly detected parasites were Balantidium coli (27.95%) followed by Eimeria sp. (16.12%), Entamoeba sp. (13.97%), Trichuris sp. (23.65%), Ascaris sp. (11.82%), Strongyloides sp. (10.75%), Oesophagostomum sp. (5.37%), Hookworm sp. (3.22%), Trichostrongylus sp. (3.22%) and Hymenolepis sp. (1.07%). Unidentified larvae of nematode which account for 6.45% of total samples were also recorded. Single, double, triple and multiple species of parasites were found in 36.55%, 29.03%, 6.45% and 2.15% samples respectively.

Published: April 2018

White clover plant, Trifolium repens L. one of the important forage crop, entirely depends on insects for its pollination. The research aims to study diversity and relative abundance of insect visitors of white clover and their relation with environmental variables in open ground of Bhaktapur Multiple Campus. Quadrate sampling method was used to explore diversity of insect visitors. Observations of the insects were conducted at morning (09:00 AM to 10:00 AM), noon (12:00 PM to 01:00 PM) and afternoon (3 PM to 4 PM) each day during study period. There were 3472 individuals of insect collected that belong to 20 species in three orders: Hymenoptera (69%), Lepidoptera (27%) and Diptera (4%). Number of individuals of visitors were comparatively higher at noon (1426) than in morning (1256) and lower in afternoon (790 individuals). Number of species found in morning and noon were same (20 species) whereas number of species found in evening was less (16 species). Apis cerana and Lampides boeticus are the most dominant species belonging to orders Hymenoptera and Lepidoptera respectively. The relation of diversity with environmental variables was correlated by using Multivariate analysis test. The test showed significant effect of light intensity, humidity, temperature and the latter one was the most influential factor on the composition of species.

Published: April 2018

Activated carbon was prepared in laboratory using waste sawdust powder of Shorea robusta (Sal) from saw mill by chemically activated Na2CO3 followed by carbonization technique. Thus prepared activated carbon was characterized by Iodine Number (IN) and Methylene Blue Number (MBN). Iodine number was found to be 534.6 mg/g whereas MBN was found to be 196.08 mg/g which indicated the presence of micropores as well as mesopores in the prepared material. This was also exposed by SEM image. Specific surface area was measured by BET method and was found to be 10.01 m2/g. Then phase state of samples was determined by X-ray diffraction (XRD), which indicated the amorphous nature of the prepared material. The development of surface functionality due to activation was examined by Fourier Transform Infrared Spectroscopy (FTIR) which showed the presence of oxygenated functional groups such as ether, diketone, lactone, phenol on the material. These functional groups are considered to be electrochemically active and contribute to the capacitance of electrical double layer capacitance (EDLC). Further, electrochemical characterization of prepared material was carried out by conductivity test and cyclic voltammetry. The cyclic voltametric curve showed symmetric rectangular shape indicating electrical double layer capacitive behavior.

Factors Affecting Population Composition and Social Organization of Wild Ungulates in the Chitwan National Park, Nepal
Authors: Bhattarai Bishnu Prasad , Kindlmann Pavel 
Published: April 2018

We investigated the factors affecting group sizes and population composition of chital (Axis axis), sambar (Rusa unicolor), hog deer (Axis porcinus), northern red muntjac (Muntiacus vaginalis), wild boar (Sus scrofa) and gaur (Bos gaurus) in the Chitwan National Park in southern Nepal. The study revealed that mean group sizes were the largest for chital (winter: 13.76 and summer: 11.01), followed by wild boar (winter: 6.89 and summer: 8.51), hog deer (winter: 5.52 and summer: 6.66), gaur (winter: 4.36 and summer: 5.81), sambar (winter: 1.86 and summer: 2.45) and muntjac (winter: 1.44 and summer: 1.46). The age and sex ratio of ungulates were biased towards females in all species. This study found the highest proportion of young individuals in wild boar and the lowest in gaur. Habitat structure, presence of predators and human disturbances strongly affected group size of ungulates in this area. Larger groups of ungulates were found in less disturbed open areas with high predatory pressure, while smaller groups and solitary individuals were found in highly disturbed forest areas. We recommend that management of human disturbances inside the park and regular monitoring of the changes in the demography of ungulate populations will improve long-term conservation strategies in this park.

Published: April 2018

The study was conducted to assess the impacts of trout farming on water quality using macro invertebrates as bio-indicators. Two trout farms were selected for the study, viz., Gandaki Trout Farm (GTF) in Kaski district and Fall & Trout Fish Farm (FTF) in Nuwakot district. Reference and impacted sites were selected in each trout farms from where macro invertebrates were collected and physico-chemical parameters were measured. Sorensen’s Index and Multiple Site Similarity Index were calculated to compare the macro-invertebrate assemblages between the impact and the reference sites. Water quality classes were also calculated using macro invertebrate-based tool, NEPBIOS/ASPT scores. Altogether 24 families of macro invertebrates were observed at GTF and 12 families at FTF. The Sorensen’s Similarity Index was greater than 0.5 between reference and impacted sites at GTF; whereas it was only 0.28 at FTF indicating comparatively low level of similarity. In addition, Multiple Site Similarity Index (0.64) at GTF also indicated high similarity between the macro invertebrate assemblages. Reference sites showed higher scores with higher diversity of macro invertebrates. Both farms had suitable water quality for trout (dissolved oxygen and temperature) and most of the physico-chemical parameters did not show significant differences except pH and turbidity at GTF probably due to small scale operation and production.

Authors: Feldmeth Michael , Müller Egon 
Published: April 2018

Kurzfassung
In der Fertigungsplanung werden Elemente, Prozesse und Strukturen eines Fertigungssystems qualitativ und quantitativ bestimmt. Zur Gewährleistung einer hohen Wirtschaftlichkeit im späteren Betrieb ist es erforderlich, dass das Planungsergebnis den Prinzipien der schlanken Produktion entspricht. Die entwickelte multikriterielle Bewertungsmethode liefert einen methodischen Beitrag für die Fertigungsplanung indem sie den Planer bei der Erzeugung schlanker Planungsergebnisse zielgerichtet unterstützt. Neben der abschließenden Variantenauswahl kommt die Bewertungsmethode bereits bei der Erarbeitung und Optimierung von Planungsvarianten zum Einsatz. Die Auswahl der Bewertungskriterien ist für die Erfolgswirksamkeit der Methode von besonderer Wichtigkeit. Diese bestimmen implizit das Planungsergebnis, da sie die Variantenentwicklung und -auswahl unmittelbar beeinflussen.

Abstract
We examine data from the Murchison Widefield Array (MWA) in the frequency range 72–102 MHz for a field of view that serendipitously contained the interstellar object ‘Oumuamua on 2017 November 28. Observations took place with a time resolution of 0.5 s and a frequency resolution of 10 kHz. Based on the interesting but highly unlikely suggestion that ‘Oumuamua is an interstellar spacecraft, due to some unusual orbital and morphological characteristics, we examine our data for signals that might indicate the presence of intelligent life associated with ‘Oumuamua. We searched our radio data for (1) impulsive narrowband signals, (2) persistent narrowband signals, and (3) impulsive broadband signals. We found no such signals with nonterrestrial origins and make estimates of the upper limits on equivalent isotropic radiated power (EIRP) for these three cases of approximately 7 kW, 840 W, and 100 kW, respectively. These transmitter powers are well within the capabilities of human technologies, and are therefore plausible for alien civilizations. While the chances of positive detection in any given search for extraterrestrial intelligence (SETI) experiment are vanishingly small, the characteristics of new generation telescopes such as the MWA (and, in the future, the Square Kilometre Array) make certain classes of SETI experiments easy, or even a trivial by-product of astrophysical observations. This means that the future costs of SETI experiments are very low, allowing large target lists to partially balance the low probability of a positive detection.
Elevation or Suppression? The Resolved Star Formation Main Sequence of Galaxies with Two Different Assembly Modes

Published: April 2018

Abstract
We investigate the spatially resolved star formation main sequence in star-forming galaxies using Integral Field Spectroscopic observations from the Mapping Nearby Galaxies at the Apache Point Observatory survey. We demonstrate that the correlation between the stellar mass surface density (Σ*) and star formation rate surface density (ΣSFR) holds down to the sub-galactic scale, leading to the sub-galactic main sequence (SGMS). By dividing galaxies into two populations based on their recent mass assembly modes, we find the resolved main sequence in galaxies with the “outside-in” mode is steeper than that in galaxies with the “inside-out” mode. This is also confirmed on a galaxy-by-galaxy level, where we find the distributions of SGMS slopes for individual galaxies are clearly separated for the two populations. When normalizing and stacking the SGMS of individual galaxies on one panel for the two populations, we find that the inner regions of galaxies with the “inside-out” mode statistically exhibit a suppression in star formation, with a less significant trend in the outer regions of galaxies with the “outside-in” mode. In contrast, the inner regions of galaxies with “outside-in” mode and the outer regions of galaxies with “inside-out” mode follow a slightly sublinear scaling relation with a slope ∼0.9, which is in good agreement with previous findings, suggesting that they are experiencing a universal regulation without influences of additional physical processes.
Dissolved Massive Metal-rich Globular Clusters Can Cause the Range of UV Upturn Strengths Found among Early-type Galaxies
Authors: Goudfrooij Paul 
Published: April 2018

Abstract
I discuss a scenario in which the ultraviolet (UV) upturn of giant early-type galaxies (ETGs) is primarily due to helium-rich stellar populations that formed in massive metal-rich globular clusters (GCs), which subsequently dissolved in the strong tidal field in the central regions of the massive host galaxy. These massive GCs are assumed to show UV upturns similar to those observed recently in M87, the central giant elliptical galaxy in the Virgo cluster of galaxies. Data taken from the literature reveal a strong correlation between the strength of the UV upturn and the specific frequency of metal-rich GCs in ETGs. Adopting a Schechter function parameterization of GC mass functions, simulations of long-term dynamical evolution of GC systems show that the observed correlation between UV upturn strength and GC specific frequency can be explained by variations in the characteristic truncation mass

such that

increases with ETG luminosity in a way that is consistent with observed GC luminosity functions in ETGs. These findings suggest that the nature of the UV upturn in ETGs and the variation of its strength among ETGs are causally related to that of helium-rich populations in massive GCs, rather than intrinsic properties of field stars in massive galactic spheroids. With this in mind, I predict that future studies will find that [N/Fe] decreases with increasing galactocentric radius in massive ETGs, and that such gradients have the largest amplitudes in ETGs with the strongest UV upturns.
