Authors: Zhang Zhongke , Li Zhao , Zhao Changzhong
Published: November 2021

With the continuous upgrading and transformation of the intelligentisation of China's manufacturing industry, and in response to the requirements for further intelligentisation of the phosphor copper ball production line proposed by a new electronic material company, this study proposes a fault prediction and diagnosis method based on big data. A high‐efficiency distributed big data platform is constructed, and a workshop‐level monitoring centre with the Windows control centre (WinCC) as the core is formed. The WinCC configuration software is used to monitor the key parameters of the equipment during the operation phase, and the login interface is configured according to the requirements of workshop information integration, for example, display interface, alarm interface, debugging interface, trend graph and other common functions. Cloud platforms and virtual private network (VPN) communication are used to realise remote maintenance. Aiming at the common fault problems in the production process, an expert diagnosis system based on fault tree analysis is constructed by fusing the fault tree theory and expert systems. The fault tree model of the unqualified phosphor copper ball production quality and the failure of the hydraulic system is highlighted. Therefore, ensuring the safety of the phosphor copper ball production line is of great significance to the entire production system.

We study the propagation of a specific class of instrumental systematics to the reconstruction of the B-mode power spectrum of the cosmic microwave background (CMB). We focus on the non-idealities of the half-wave plate (HWP), a polarization modulator that is to be deployed by future CMB experiments, such as the phase-A satellite mission LiteBIRD. We study the effects of non-ideal HWP properties, such as transmittance, phase shift, and cross-polarization. To this end, we developed a simple, yet stand-alone end-to-end simulation pipeline adapted to LiteBIRD. We analyzed the effects of a possible mismatch between the measured frequency profiles of HWP properties (used in the mapmaking stage of the pipeline) and the actual profiles (used in the sky-scanning step). We simulated single-frequency, CMB-only observations to emphasize the effects of non-idealities on the BB power spectrum. We also considered multi-frequency observations to account for the frequency dependence of HWP properties and the contribution of foreground emission. We quantified the systematic effects in terms of a bias Δr on the tensor-to-scalar ratio, r, with respect to the ideal case without systematic effects. We derived the accuracy requirements on the measurements of HWP properties by requiring Δr < 10−5 (1% of the expected LiteBIRD sensitivity on r). Our analysis is introduced by a detailed presentation of the mathematical formalism employed in this work, including the use of the Jones and Mueller matrix representations.

We performed the first detailed spectral analysis of red giant members of the relatively high-metallicity globular cluster (GC) Tononzintla 2 (Ton 2) using high-resolution near-infrared spectra collected with the Apache Point Observatory Galactic Evolution Experiment II survey (APOGEE-2), obtained as part of the bulge Cluster APOgee Survey. We investigated chemical abundances for a variety of species including the light, odd-Z, α-, Fe-peak, and neutron-capture elements from high S/N spectra of seven giant members. The derived mean cluster metallicity is [Fe/H] = −0.70 ± 0.05, with no evidence for an intrinsic metallicity spread. Ton 2 exhibits a typical α-enrichment that follows the trend for high-metallicity Galactic GCs, similar to that seen in 47 Tucanae and NGC 6380. We find a significant nitrogen spread (> 0.87 dex), and a large fraction of nitrogen-enriched stars that populate the cluster. Given the relatively high-metallicity of Ton 2, these nitrogen-enriched stars are well above the typical Galactic levels, indicating the prevalence of the multiple-population phenomenon in this cluster that also contains several stars with typical low first-generation N abundances. We also identify the presence of [Ce/Fe] abundance spread in Ton 2, which is correlated with the nitrogen enhancement, indicating that the s-process enrichment in this cluster has likely been produced by relatively low-mass asymptotic giant branch stars. Furthermore, we find a mean radial velocity of the cluster, −178.6 ± 0.86 km s−1, with a small velocity dispersion, 2.99 ± 0.61 km s−1, which is typical of GCs. We also find a prograde bulge-like orbit for Ton 2 that appears to be radial and highly eccentric. Finally, the considerably nitrogen-enhanced population observed in Ton 2, combined with its dynamical properties, makes this object a potential progenitor for the nitrogen-enriched field stars identified so far toward the bulge region at similar metallicity.

Authors: Saptati Ratna Ayu , Priyono
Published: November 2021

The gap of growth in milk consumption that is not in line with the growth of milk production has resulted in the need for imports. Indonesian government intervenes in import regulation through the implementation of import tariff policy and strategic programs to increase domestic milk production. The study aimed to analyze the impact of the integration of both interventions on accelerating the growth of fresh milk production in Indonesia. The research method is a descriptive method that uses BPS, Pusdatin, and other second-hand data published in previous studies. A comparative study of producer and consumer surplus and a modeling analysis of strategic policies to increase the production of domestic fresh milk was used. The results of the analysis revealed that the impose of 5% import tariff on milk has an impact on increasing producer surplus, decreasing consumer surplus and public welfare, also increasing the government’s revenue. The results of model simulation showed that the recommended combination scenario of increasing milk productivity, calf rearing, and broodstock import is the best scenario. Hence, the import tariff policy recommendations combined with the strategic programs can accelerate the increase in the supply of fresh milk in Indonesia.

Published: November 2021

The Integrated Crop Livestock Systems (ICLS) is considered an important strategy to cope with climate change issues in coffee plantations. However, the involvement of women in the coffee livestock integration system is still limited. This condition is related to women’s limited knowledge and technical capacity because there is no technology transfer model based on the requirements and needs of women. The purpose of this paper is to identify problems related to women’s participation and formulate technology transfer strategies to increase women’s participation in coffee livestock integration as a Climate-Smart Agriculture (CSA) practice. The research was conducted in Bandung Regency, West Java, as Indonesia’s Arabica coffee development center. Data analysis was performed using descriptive statistics and Interpretive Structural Modeling (ISM). The role of women in management and decision-making in the development of coffee livestock is relatively low. Their involvement is still complementary, lacking initiative and limited participation due to internal and external issues. The strategies are related to three main areas: knowledge development, skill development, and technology utilization. The program derived from the strategies is expected to develop women’s capacity both individually and in groups.

This study utilized a qualitative research method with a case study approach. The findings were obtained from in-depth-interviews and documentation. Environmental communication itself is a plan and strategy through the communication process and media products to support policymaking, public participation, and its implementation in the environment. The results showed that environmental communication was carried out in Subak Sembung through socializing, counseling initiated by Subak Sembung, and collaborating with the local government. The communication environment also applied Tri Hita Karana (THK) values in Subak to sustain and promote Subak as ecotourism. The THK guides human behaviors in three critical relationships in their lives: the relationship between humans (pawongan), the environment (palemahan), and with God (parahyangan). Balance and harmony in these relationships are essential to achieve sustainability.

Community empowerment has been reported to lead to societal dependence, as symptoms tend to allow the population not to be independent. In the coastal area of Bengkulu City, community empowerment has been reported to be carried out, most especially among the fishing population. However, it was not conducted sustainably, resulting in independence for the fishing community. For example, several Agencies often assist with temporary benefits. Moreover, there is no evaluation of program outcomes, as the assistance services do not run optimally. This study aims to describe the stakeholder collaboration patterns in empowering the coastal community at Bengkulu city. The method used was descriptive qualitative, as data were collected through observations, interviews, and documentation. The determination of objects was also carried out via the use of purposive and convenience sampling techniques. Also, the triangulation technique was used in order to check the data validity. The results showed that stakeholder collaboration was not being efficient and effective. The indicators also showed that the involved stakeholders have not entered into agreements and cooperation, which were observed as an effort to increase the capacity of coastal communities.
