Conceptualization of containment in Chinese
Authors: Su Hung-Kuan , Chen Alvin Cheng-Hsien
Published: October 2019

This study investigates the semantic variations of three near-synonymous space particle constructions of
containment in Chinese: [zài NP lǐ/nèi/zhōng]. While previous work has mostly applied
qualitative analyses of the semantic differences between these particles, this study presents a corpus-based analysis examining
the relationship between space particles and their co-occurring landmarks in the locative construction. Two quantitative analyses
were conducted: a multiple distinctive collexeme analysis and a post-hoc semantic analysis. Our results suggest the following.
First, lǐ is a more unmarked particle in encoding containment, co-occurring with both canonical landmarks and a
wider range of entities. Second, nèi shows a strong preference for landmarks denoting temporal concepts; this
metaphorical use often implies a preplanned objective in the proposition, with the landmark as an intended deadline. Finally,
zhōng shows a strong connection to landmarks denoting high-dynamicity events. This extended use often comes
with a marked aspectual reading of the landmark.
Acceptability of Technological Solutions for Overdose Monitoring: Perspectives of People who use Drugs
Authors: Tsang V. W. L. , Papamihali K. , Crabtree A. , Buxton J. A.
Published: October 2019

Introduction

Rising overdose deaths are a devastating problem across the United States and Canada. Despite the availability of observed consumption sites in British Columbia (BC), data suggest people who use drugs (PWUD) alone in private residences are most at risk of overdose death. These individuals may not use consumption sites due to fear of stigmatization, lack of privacy, or personal preference. It is this population that would benefit from overdose monitoring alternatives.

Methods

This 2018 study employed two sources of data. (1) A provincial harm reduction distribution site client survey administered at 27 sites across BC asked about cell phone possession and functionality. (2) Structured interviews with PWUD in Vancouver gathered perspectives regarding monitoring devices and alerting systems.

Results

The client survey was administered to 486 individuals. Among 443 respondents, 48% ( n = 212) owned a cellphone and 68% ( n = 115) of individuals with a cellphone with access to internet ( n = 168) would use an application to mitigate opioid-related overdose deaths. Thirty qualitative interviews were performed; thematic analysis of the responses identified three major themes – safety, public versus private drug use, and technological monitoring and function. The relevance of technological devices was affected by the inconsistent availability of cellphones, concerns about anonymity, as well as personal comfort while using drugs.

Conclusions

Technological applications may not be suitable for clients with transient lifestyles, no permanent home, and lack of consistent access to a mobile device. Thorough needs assessments, considerations of lifestyle limitations, and understanding perceptions around cellphone and overdose monitoring can increase the potential that devices will be used.

Highlights

• 45% ( n = 219) of client survey respondents owned a cellphone • Out of cellphone owners, 59% ( n = 102) of client survey respondents had access to internet • Of 168 with internet access, 68% willing to use any applications for overdose response • Applications not suitable for transient lifestyles, no permanent home, and lack of consistent access to cellphone
Quantum state transfer via acoustic edge states in a 2D optomechanical array
Authors: Lemonde Marc-Antoine , Peano Vittorio , Rabl Peter , Angelakis Dimitris G
Published: October 2019

We propose a novel hybrid platform where solid-state spin qubits are coupled to the acoustic modes of a two-dimensional array of optomechanical (OM) nano cavities. Previous studies of coupled OM cavities have shown that in the presence of strong optical driving fields, the interplay between the photon-phonon interaction and their respective inter-cavity hopping allows the generation of topological phases of sound and light. In particular, the mechanical modes can enter a Chern insulator phase where the time-reversal symmetry is broken. In this context, we exploit the robust acoustic edge states as a chiral phononic waveguide and describe a state transfer protocol between spin qubits located in distant cavities. We analyze the performance of this protocol as a function of the relevant system parameters and show that a high-fidelity and purely unidirectional quantum state transfer can be implemented under experimentally realistic conditions. As a specific example, we discuss the implementation of such topological quantum networks in diamond based OM crystals where point defects such as silicon-vacancy centers couple to the chiral acoustic channel via strain.
Analog nature of quantum adiabatic unstructured search
Authors: Slutskii Mikhail , Albash Tameem , Barash Lev , Hen Itay
Published: October 2019

The quantum adiabatic unstructured search algorithm is one of only a handful of quantum adiabatic optimization algorithms to exhibit provable speedups over their classical counterparts. With no fault tolerance theorems to guarantee the resilience of such algorithms against errors, understanding the impact of imperfections on their performance is of both scientific and practical significance. We study the robustness of the algorithm against various types of imperfections: limited control over the interpolating schedule, Hamiltonian misspecification, and interactions with a thermal environment. We find that the unstructured search algorithm’s quadratic speedup is generally not robust to the presence of any one of the above non-idealities, and in some cases we find that it imposes unrealistic conditions on how the strength of these noise sources must scale to maintain the quadratic speedup.
Invariants of motion with stochastic resetting and space-time coupled returns
Authors: Pal Arnab , Kuśmierz Łukasz , Reuveni Shlomi
Published: October 2019

Motion under stochastic resetting serves to model a myriad of processes in physics and beyond, but in most cases studied to date resetting to the origin was assumed to take zero time or a time decoupled from the spatial position at the resetting moment. However, in our world, getting from one place to another always takes time and places that are further away take more time to be reached. We thus set off to extend the theory of stochastic resetting such that it would account for this inherent spatio-temporal coupling. We consider a particle that starts at the origin and follows a certain law of stochastic motion until it is interrupted at some random time. The particle then returns to the origin via a prescribed protocol. We study this model and surprisingly discover that the shape of the steady-state distribution which governs the stochastic motion phase does not depend on the return protocol. This shape invariance then gives rise to a simple, and generic, recipe for the computation of the full steady state distribution. Several case studies are analyzed and a class of processes whose steady state is completely invariant with respect to the speed of return is highlighted. For processes in this class we recover the same steady-state obtained for resetting with instantaneous returns—irrespective of whether the actual return speed is high or low. Our work significantly extends previous results on motion with stochastic resetting and is expected to find various applications in statistical, chemical, and biological physics.
Asymmetric twin-field quantum key distribution
Authors: Grasselli Federico , Navarrete Álvaro , Curty Marcos
Published: October 2019

Twin-Field (TF) quantum key distribution (QKD) is a major candidate to be the new benchmark for far-distance QKD implementations, since its secret key rate can overcome the repeaterless bound by means of a simple interferometric measurement. Many variants of the original protocol have been recently proven to be secure. Here, we focus on the TF-QKD type protocol proposed by Curty et al (2019 NPJ Quantum Inf.
5 64), which can provide a high secret key rate and whose practical feasibility has been demonstrated in various recent experiments. The security of this protocol relies on the estimation of certain detection probabilities (yields) through the decoy-state technique. Analytical bounds on the relevant yields have been recently derived assuming that both parties use the same set of decoy intensities, thus providing sub-optimal key rates in asymmetric-loss scenarios. Here we derive new analytical bounds when the parties use either two, three or four independent decoy intensity settings each. With the new bounds we optimize the protocol’s performance in asymmetric-loss scenarios and show that the protocol is robust against uncorrelated intensity fluctuations affecting the parties’ lasers.

Published: October 2019

The Village RPJM, also known as the Village Medium Term Development Plan, is something that must be prepared very carefully. The Village RPJM, especially the Sukadamai village, currently uses intuition alone, even the data held by the village head is still not updated. So that the Village RPJM does not provide maximum results. Therefore, it is necessary to make an intelligent system that can help the village head in determining the potential commodities in Sukadamai village. The latest data with high precision was obtained with the help of the IPB PSP3 using drones and participant assistance. This intelligent system uses a Fuzzy Inference System (FIS) to determine the commodities that have potential in the town of Sukadamai. The input variables used in this study are 10. For the potential of the land and market potential, each of the 27 rules and for the potential of the citizens to produce 64 rules. In the next FIS process, it produces 27 rules to get a potential commodity, so the total rules obtained are 145 rules. Hopes that with this intelligent system, in making the Village RPJM, the village government can be more focused on developing superior commodities in the Sukadamai village.

Moreover, the prediction model could obtain the value of 0.8346, 0.6812, and 0.5319 for accuracy, Gmean, and AUC, respectively.
Analysis of farming efficiency and smart farming system development in supporting garlic self-sufficiency: A concept
Authors: Waryanto B , Agustina T , Tjiptodharmono D
Published: October 2019

In Indonesia, the agricultural sector has a strategic role in sustaining the national economy. Various policies have been made with the aim of increasing the strategic role, both in the form of policies to achieve food self-sufficiency, reduce imports and even policies to encourage exports. One of the important commodities in the agricultural sector is garlic. This commodity is the government’s priority to be managed and targeted for self-sufficiency by 2021. This paper tries to trace the success of garlic farming through data studies and related literature. The review of existing data shows that over the past four years (2014 to 2017) the ratio of garlic production to imports was very small just only 4.15%, indicating that Indonesia still depends on imported garlic. Amount of imported garlic grew 5.09% per year, but on the other hand, domestic production grew negatively -1.73%, meaning that domestic production is still not enough for domestic consumption. As a discouraging form towards the achievement of self-sufficiency, this paper also reviewed the literature on the efficiency concept of garlic farming at the farm level through the approach of econometric models, as well as the concept of developing smart farming systems used for product tracking functions to the consumer level, on the contrary can be traced back to products produced by farmers. Through the offering of these two thought concepts, it is expected to be contribute in supporting the government program to achieve garlic self-sufficiency.

Authors: Gaffar A W M , Sitanggang I S
Published: October 2019

Sugarcane which is the main ingredient of sugar production has a very high production demand so it must have a balance with the level of productivity. Sugarcane productivity in Indonesia can only reach 5.8 tons/ha which is still relatively low. In recent years sugarcane farmers have felt the decline in sugarcane production due to climate change which has affected the success of sugarcane planting so that sugar production has not been in line with national needs. This study aims to build a prediction model for the productivity of sugarcane crops in each area of Java Island based on climatic factors. The climate data used are collected from Indonesian Agency for Meteorology, Climatology, and Geophysics from 2006 to 2015. The method used is Support Vector Regression (SVR) using a radial base kernel function with a generalized neighbourhood matrix as a spatial model. The prediction model has RMSE of 0.1203954 and correlation of 0.9459743. The results of visualization of sugarcane productivity mapping show that areas in East Java have a higher value of productivity increase than areas in other provinces. Based on the results obtained, the model used has a quite good performance in predicting the productivity of sugarcane.

Design for improvement of sugar factory performance based on statistical thinking
Authors: Kustiyo A , Arkeman Y
Published: October 2019

The amount of sugar production is determined, among others, by the quality of sugar cane and the performance of sugar factory equipment. The quality of sugar cane as an agricultural product is influenced by the quality of sugar cane seeds, soil conditions and climate. The differences in the factors affect the quality of sugarcane production. Sugarcane milling is not based on the quality of sugarcane but on the arrival time to the factory. Under this condition, different sugarcane qualities will be milled together. As a consequence, it may not yield the optimal sugar production. In the sugar production process, equipment performance must always be monitored. Equipment failure will reduce the amount of sugar produced. Therefore, efforts to increase sugar production must consider both factors, namely the variation of input quality and monitoring of equipment performance. One approach in solving this problem is statistical thinking approach. The purpose of the paper is to design the performance improvement of sugar factory based on statistical thinking. The improving activity based on statistical thinking will concentrate on manufacturing process enhancement and problem breaking that rely on realizing and degrading variation. The study shows that the statistical thinking approach potentially able to increase sugar production using process enhancement framework and overcome factory equipment failure using problem breaking framework.

Published: October 2019

Research to study demersal fish in Kotania Bay was conducted from June 2017 to August 2018. The results showed that demersal fish species fished in Kotania Bay consisted of 99 species from 6 families namely Serranidae, Lutjanidae, Scaridae, Lethrinidae, Mullidae and Labridae. The most abundant species groups were species of family Serranidae and Lutjanidae (35 and 25 numbers of species respectively). Demersal fish species are mainly used for human consumption and the caught tend to have high value, therefore, fishers in Kotania Bay exploited the demersal fish intensively. Several important species of family Serranidae and family Lutjanidae are the most abundant fish species in the caught, but some of demersal fish in Kotania Bay are now overexploited, this trend has appeared since the year 2000’s. Low fish catch and income of most fishers along coast of Kotania Bay and in addition to their reliance on fishing as a livelihood, has contributed to continued overexploitation. Fishing activities of demersal fish in Kotania Bay depend on monsoon, and the high catch of fish was in January, February, and March (4,560, 4,200 and 3840 kg respectively). Regarding to the overfished of demersal fish in Kotania Bay, therefore, are recommended some forms and regulations of management for demersal fisheries recovery and sustainability, such as restrictions fishing gears, collaboration stakeholders between levels of management, control of demersal fish utilization, alternative livelihood for fishers, protection habitat of fish through conservation and rehabilitation program, and encouraging co-management.

The increase in CO2 in the air has caused global warming, the impact of which is felt by everyone in the world. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity of natural forests and increasing the density of trees outside the forest. Mangrove forests have a role as absorbers of CO2 from the air, and save more carbon than most tropical rainforests. The purpose of this study was to determine the biomass, stock carbon and CO2 uptake of mangrove Sonneratia alba in the Passo coastal waters, Inner Ambon Bay. Sampling of mangrove S. albaby belt transect method with a belt width of 10 m. Data collected included the number of trees, diameter (DBH) and area of observation. Biomass analysis and carbon content of S. albatrees were carried out in a nondestructive way (without damaging plants), which was using biomass estimation allometric equations. Carbon (CO2) uptakein S. alba is 564.48 tons.ha−1 which is stored on above of the ground at 111.50 tons.ha−1 and below the ground at 42.31 tons.ha−1. Total stock carbon of 153.81 tons.ha−1 were converted from total biomass of 327.26 tons.ha−1. High carbon sequestration and storage is supported by high biomass and high biomass is supported by a high number and diameter of trees.

Seagrass bed is one of important ecosystems usually located adjacent to coral reefs and serves several important ecological roles such as feeding and nursery ground for several marine biotas. Physically, seagrass bed protects the reef from inland sedimentation. The status of seagrass beds, therefore, becomes an important thing in protecting the coral reef ecosystem. The study was conducted on July 2018 with the objective to analyze the current status of seagrass bed at Coral Reef Rehabilitation and Management Program (COREMAP) site in Ternate Island. Ten stations were chosen for this study and linear transect method was used to analyze species composition and canopy coverage. The result showed that there are 8 species found in this area with 5-7 species commonly found at each station. Among 8 species found, Thalassia hemprichii being the most common species inhabiting all of the sites. Average canopy coverage in seven stations was below 59.9% which considered as less healthy, whilst at other three locations was below 29.9% which considered as poor status. Overall, the status of seagrass beds in this area is less healthy with moderate canopy cover. This status has remained the same since 2015 to the present time.

Sea turtles are one of those protected animals according to government regulation no. 7 1999. Living turtle migrates along area the Pacific Ocean, the Indian Ocean, and Southeast Asia Ocean including Sea of Halmahera. In Indonesia, there are 6 species of 7 species of sea turtle in the world and 3 of them are in The Meti Island namely the green sea turtles (Chelonian mydas), hawksbill sea turtle (Eretmochelys imbricata) and olive ridley sea turtle (Lepidocheys olivacea). All species of sea turtles in Indonesia categorized as a protected animal, but until now the exploitation of sea turtle still widely practiced by the community of The Meti Island. The objective of this study, therefore, was to analyze the knowledge and community understanding of existence and the utilization of the sea turtle. The data was taken through observation of sea turtle existence and interview with The Meti Island community. The result showed as 68.15 % of respondents knows about the existence of sea turtle, 37.5 % know about the impact of utilization to its sustainability but 43 % still harvesting and using sea turtle as a consumption and trade. This shows the lack of awareness in the community about the sustainability of sea turtle around The Meti Island. The high level of utilization of sea turtle shows the weakness of the function in the monitoring and supervision by the regional government against the utilization of an animal that should have to be protected.

Data analysis on sea water quality data in Jakarta Bay using Principal Components Analysis (PCA) method during transitional monsoon 2012
Authors: Martina A , Radjawane I M
Published: October 2019

To get a conclusion from a data matrix consisting of 3 individuals and 2 variables is relatively easy. However, it is very difficult to understand the large amount of data. Therefore, it requires data analysis methods for an easier representation. Based on sea water quality data in Jakarta Bay from BPLHD DKI Jakarta (Jakarta Environmental Management Board), there are 24 biological, physical, and chemical parameters in 23 stations. Based on the quality and quantitative of data, we use only one set data on October 2012 as representative of the Second Transition monsoon. Analysing was conducted for 10 parameters namely turbidity, total suspended solid (TSS), temperature, pH, salinity, dissolved oxygen (DO), biological oxygen demand (BOD), methylene blue active substances, phenol, and zinc (Zn) at 23 stations. Consequently, in this paper, we get a conclusion from the data using principal component analysis (PCA) method for its application in data analysis. The method of PCA is used to analyse the data matrix from a similarity point of view between stations and correlation between parameters. The result of PCA is four principal components i.e. PC 1 (27.73% of the variance) is mainly related to TSS, temperature, salinity, and DO. PC 2 (16.33% of the variance) is mainly related to BOD. PC 3 (12.39% of variance) is mainly related to MBAS, phenol, and zinc. PC 4 explains 11.09% of variances related mainly to turbidity.

The Banda Sea experiences a strong upwelling between April and November associated with the seasonal strengthening of the trade winds. Data of surface wind, sea surface temperature (SST) and salinity in the period of 1990-2008 were used to further study the response of upwelling to the local and remote forcing in the Banda Sea. A local forcing (Ekman Pumping) during Southeast Monsoon plays role in contributing the upwelling intensity indicated by shallower thermocline and colder SST. In addition, this study exhibits that the upwelling strength is controlled remotely by El Ñino Southern Oscillation (ENSO) where during El Niño (La Niña) periods in Southeast Monsoon, the upwelling weakens (strengthens) in the Banda Sea.

The deviation of the sea surface from the geoid reference surface is known as the Sea Surafce Topography (SST). SST is caused by several physical phenomena such as ocean wave, tides, current and atmospheric pressure loading, and the main application of SST is to determine ocean circulation. To get the SST, we use Sea Surface Height (SSH) and Mean Dynamic Topography (MDT) based on 30 years of sea-level data derived from multi-mission of satellite Altimetry and geoid height (Undulation) from Global Gravitation Model EGM-2008. Indonesia is an archipelagic country in the equatorial region that lies between Indian and Pacific oceans. Its geographical setting will affect variability of Sea Surface Topography (SST) in the Indonesian Sea. The anomaly from SST is one of the oceanic parameters that play a crucial role in the ocean dynamic and its possible hazards. We found that the characteristics differ considerably from one place to another, depending on the bathymetric depth and type of sea. The mean SSH varies from about 40 meters and rises to the east up to a height of 80 meters. Likewise, the MDT value increased from 0.5 meters to the east to a height of 1.2 meters. In closed, narrow and shallow seas, the long time-series of those surfaces are less sensitive to the effects of El Niño and La Niña as well as global sea level rise. On the other hand, global sea level rise significantly affects the characteristic of both surfaces over open and deep seas. We hope by using more spatially dense data from multi-mission satellite altimetry, we can see more detail about the local phenomena that influence SST. By studying the variability of SST from more than one cycle (18.6 years) it is expected that it can be used to understand the dynamics of the coastal area in Indonesia.

Ship engine power is estimated at initial design process to satisfy the required speed. This ship parameter is determined by computation of ship resistance and propulsion parameter from any existing methods or executing ship model test. In fact, the results of ship model tests do not satisfy those of the existing methods. However, for initial design approach this may be used to estimate the engine power. This approach is used in design process for many ships but some methods are not suitable for certain type of ships. Three type of ships were developed and evaluated to prove this issue. They were fishing ship, passenger-cargo coaster and semi-displacement ship. The resistance and propulsion parameters of those ships were determined by the existing methods. Three models of those ships were tested in the towing tank to validate the results of the resistance from existing methods. The results of computation and model test were presented and analyzed. It was found that there were difference between the results of computations and those from model tests for three ships. Some recommendations were stated at this paper concerning the application of the results for such ships.
Prevalence of hypertension and efforts to develop a monitoring system for hypertension in community living in the coastal areas of Noloth and Itawaka Village, Saparua Island, Central Maluku District
Authors: Que B J , Ihalauw C Y , de Lima F
Published: October 2019

Hypertension is a chronic medical condition due to the increased blood pressure. Uncontrolled hypertension might cause several complications, including stroke, heart and kidney disease. More complex problems for patients and families emerge when complications occur. The 2014 Health Profile of Maluku Province reported that the prevalence of hypertension in population aged 18 years or above was 457,152 people and only 50.74% had their blood pressure measured. This prevalence rate was low compared to the prevalence reported by The 2013 Basic Health Research (Riskesdas). The low prevalence rate was due to the shortage of facilities and medical personnel to conduct hypertension examinations, in addition to the low motivation of the community to have a regular blood pressure check. In 2014, the number of non-communicable diseases in Central Maluku was considered high but the incidence rate of hypertension was low. However, most of the non-communicable diseases were associated with hypertension. This study was aimed to develop a monitoring system in dealing with hypertension patients of Itawaka and Nolloth village. From secondary data obtained in 2015, there were 4.2% of 8.660 individuals from East Saparua who suffer from hypertension. It was also found that regular checkup of patients and their compliance on taking hypertension drug was low. We propose a monitoring mechanism as follows: screening patients with hypertension, mapping their location, develop patient forms on application in smartphone, filling out patients’ record according to their residence, assigning health workers responsible in the specified area and on a weekly basis monitor blood pressure and their compliance with taking anti hypertensive drugs.
Hybrid solar-wind-diesel power plant for small islands in Maluku Province
Authors: Pelupessy D , Manuhutu F
Published: October 2019

Maluku Province is an archipelagic province consist of 1,340 islands mostly classified as small island and has the total area of 712,479.69 km2 of which 658,331.52 km2 (92.4%) are marine and only 54.15 km2 (7.6%) are terrestrial. This geographic condition causes high insularity and approximately 34% of villages in Maluku are without electricity and it is highly impossible to provide every remote small island with the power supply. Solar and wind penetration into existing diesel systems can be considered as a breakthrough to meet the need for power supply for these remote islands. A techno-economic analysis is applied to perform a design of an optimal hybrid solar-wind-diesel power plant to serve the load of the villages at these remote islands. The hybrid plant can reduce cost about 20% as well decrease of greenhouse gas emissions of diesel generator alone. Based on the result obtained, the villages in Maluku Province particularly those at the remote area are the potential candidate for deployment of the proposed hybrid solar wind-diesel power plant for electricity generation.

In the search for new and renewable energy, Gracilaria sp. was studied as the raw material for bioethanol production. This seaweed is available abundantly in the very long Indonesian coastline. This study investigates the effect of several pretreatment methods on the concentration of sugar produced from Gracilaria sp. when hydrolyzed using cellulase or sulphuric acid. Reducing sugar was measured by UV-Vis spectrophotometry using Nelson-Somyogi reagent and the ethanol concentration was measured by using gas chromatography. Cellulase and sulphuric acid (H2SO4) were used in the hydrolysis. Cellulase concentration used was 200, 400, 600 and 800 units/ml, whereas the concentration of sulphuric acid used was 1%, 3%%, 5%, and 7%. The highest concentration of reducing sugar was produced by hydrolysis using H2SO4 1%.

Lermatang Village is situated at Southwest Maluku Regency and is known as a producer of seaweed. Generally, the seaweed produced in this village belongs to Eucheuma cottonii, which is a source of carrageenan and has high economic value. Carrageenan is known as raw material for the pharmaceutical, cosmetic, food and other industries, as gelling agents, material binders, emulsifiers, and stabilizers. The most common problem faced by the seaweed grower was they haven’t been able in optimizing the processing technologies yet. The seaweed farmer is still selling the seaweeds in form of dry seaweed without further processing and this cause a low price. The aim of this research was to study the physicochemical properties of carrageenan of Eucheuma cottonii originated from Lermatang Village fo Southwest Maluku Regency. Seaweed was extracted by using sodium hydroxide then physicochemical properties of carrageenan were observed. The results showed that physicochemical properties of carrageenan were indicated by yield 34.50 – 44.25 g, gel strength 500 - 850 g/cm2, viscosity 35.2- 40.89 cP, water content 14.32-25.73%, ash content 21.34-22.62% and sulphate content 14.85-16.50%.
