Published: August 2023

Abstract

Black Soldier Fly (BSF) has been well studied for many purposes including its utilization as fish feed and decomposer of organic waste. At the grassroots level, this species is used for alleviating the household waste problem, however, long-term mass rearing becomes challenging due to the high mortality and declining size of larvae, and its nutritional content as an alternative to fish feed becomes a question. The objective of this study is to evaluate the effects of different types of household organic waste on larval development, mortality rate, and nutrient content when larvae enter pre pupa stage. Seven days old larvae were maintained with five different types of fresh household organic waste, vegetable waste, animal waste, and mixed waste with three different combinations between vegetable and animal waste with proportions 1:1, 1:3, and 3:1. There are five units for each treatment with each unit containing 50 larvae. Larval morphometry and volumetry, Waste Reduction Index/WRI, Survival Rate/SR, and proximate analysis were observed. Types of Organic household waste significantly affect the mortality, development, and nutrient content of BSF larvae. BSF larvae maintained with a combination of vegetable waste and animal waste with a ratio of 3:1 have a better quality in terms of mortality, development, and nutrient content.

Abstract
‘More than 50% of Indonesia’s mangrove is lost over the last 30 years, which makes Indonesia has the fastest rate of mangrove destruction in the world. East Kalimantan Province has the third largest mangrove in Indonesia, behind Papua and Riau Province. Mangroves in East Kalimantan experienced great pressure from land conversion into ponds. Hence, this study focuses on mangrove and pond conversion trendlines based on 3 times spatial analyses using an automated method through the Google Earth Engine (GEE) platform using Landsat from 1990, 2000, and Sentinel 2019 imagery data. The total area of mangroves identified in 1990 was 268,147 Ha, in 2000 was 227,202 Ha or a decrease by 15%, and in 2019 was 215,514 Ha or a decrease by 5%. The amount of mangrove area that continues to decrease is aligned with the pond increasing in all East Kalimantan that identified in 1990 was 9,935 Ha, then extremely increase until in 2000 identified an area of 61,083 Ha and increased again in 2019 to reach 86,471 Ha. The analysis shows that it is dominated by the conversion of mangroves to ponds throughout East Kalimantan reaching 65% of the total reduction that occurred both in the period 1990-2000 and 2000-2019.

Abstract
Late blight disease is one of the problems faced by potato farmers. Chemical fertilizer and biological fertilizer (bio-fertilizer) reported have a potential to control late blight disease. However, there is a lack of research on the effect of combining the use of different types of bio-fertilizers with different doses of chemical fertilizers in potato plants to late blight disease. This study aims to analyze the effect of combining different types of bio-fertilizers and doses of chemical fertilizers on late blight disease in potato plants. This research was conducted from June to August in Sembalun District, West Nusa Tenggara Province. This study used fifteen combination treatments of bio-fertilizers and doses of chemical fertilizers. Each of these treatments included: A (control); B, C, D, E (bio-fertilizers, without chemical fertilizers); Treatment F, G, H, I (bio-fertilizers, chemical fertilizers 100%); J, K, L, M (bio-fertilizers, chemical fertilizers 50%); N (without bio-fertilizer, 100% chemical fertilizer) and O (without bio-fertilizer, chemical fertilizer 50%). The results showed that there was no significant difference in the effect of the combination of different bio-fertilizers and doses of chemical fertilizers on late blight severity.

Published: August 2023

Abstract
This study aims to comprehend the challenges and opportunities to implement certification in the small-scale octopus fisheries in North Minahasa through the Socio-ecological System (SES). The background of this research is because Indonesian octopus has a potential for export. However, octopus was listed under concern due to unsustainable fisheries practices. In addition, the export activity must be accompanied by an eco-label certification scheme such as Marine Stewardship Council (MSC) and Fair Trade (FT). This study used a qualitative case study by online interviews with stakeholders such as fishers, middlemen, exporters, and the government-non government organization. The result was that local actors started to become aware of the octopus improvement program through cooperation with an NGO in a program called Rumah Boboca; hence, it is not ready to implement certification. The recommendation is to support improvement with an octopus national management plan (RPP) and a basic Fishery Improvement Project (FIP).

Authors: Peralta M A , Navarra N 
Published: August 2023

Abstract
The public’s demand for more open spaces as brought about by the effects of the pandemic has resulted in increased interest in an existing brownfield in La Union. The San Juan Municipal Cemetery is located along the National Highway, near the existing tourism destination of the municipality. Its presence has raised concerns about it being a visual blight as it is visible from the highway. According to the Comprehensive Land-Use Plan (CLUP) of the Municipality of San Juan, La Union (SJLA), the existing Municipal (People’s) Park is 11,500 square meters (sqm). The 2022 Area Requirement for SJLU’s recreational spaces is estimated at 30,907 square meters (sqm). However, the lack of recreational function and facilities of the San Juan Municipal Cemetery may lead to its removal from the total open space for recreational spaces, resulting in the reduction of the total area to only 19,407 square meters (sqm). This may affect the capacity of the municipality to provide for the residents’ recreational needs, forcing the residents to travel to other cities for their recreational needs. This leads to the examination of the function of memorial parks in their everyday function, their significance in the economic development, environmental risks, and tourism value for the residents. Using a descriptive methodology in gathering insights from the relevant Experts on culture, environment, culture, and tourism, the research found the necessity of converting this memorial park into a culturally-relevant space that reflects the identity of the residents while at the same time improving the tourism image of the municipality.

This research was conducted in Teluk Rimba Village, Koto Gasib District, Siak Regency, Riau Province. The sustainability analysis used was Multidimensional Scaling (MDS). The sustainability status category in this study is based on four basic scales (0-100); 24.9 (poor); 25-49.9 (less); 50-74.9 (enough); and > 75 (good), then a leverage analysis is performed to assess sensitive attributes. The results showed that water management in Koto Gasib District is in a very sustainable status with a value of 84.17. In the environmental dimension, land fertility is the most important aspect of oil palm productivity. In the economic dimension, farming capital and access to marketing are sensitive attributes. The social dimension has the most sensitive attributes. The technology dimension has two sensitive attributes, namely information and the introduction of water management technology as well as oil palm cultivation. The recommendations given are implementing a partnership in water management between private oil palm plantations and smallholder plantations.
Challenges of transforming Indonesia’s circular economy in the context of electric vehicle policy
Authors: Wulansari I , Aziz V 
Published: August 2023

Abstract
The circular economy is the application of sustainable industrial behavior through the implementation of low-carbon technology. Electric vehicles are one of the low-carbon technologies that are a priority for sustainable business policies in Indonesia. Ecological modernization is characterized by the existence of policy-based structures and mechanisms that support sustainable technologies. The ecological modernization study observed in this paper is a policy instrument for developing sustainable infrastructure and technology that supports sustainable business through Presidential Regulation Number 55 of 2019. In addition, the government has issued a ban on nickel ore exports since January 1, 2020. However, the ban on Indonesia’s nickel ore exports has become a free trade dispute through the European Union’s lawsuit to the WTO (World Trade Organization). The transformation of Indonesia’s circular economic policy faces the dilemma of the global free trade structure. Furthermore, the transformation of Indonesia’s circular economy policy provides a perspective that ecological modernization is a business with a new, greener face that does not touch the transformation of the order of power relations in a just global structure. However, the circular economy narrative focuses more on the agenda of building business opportunities that lacks narratives on the reorganization of ecological relations.

Published: August 2023

Abstract
A wide-angle and polarization-sensitive metamaterial absorber is highly desired for near-infrared optical applications, such as stealth coatings, photovoltaic materials, and detectors. Although current near-infrared metamaterial absorbers achieve high absorption rates, they are typically either polarization-independent or only sensitive to one direction. Herein, a (CH3NH3)PbBr3-based perfect absorber with high absorption in both orthogonal directions and polarization sensitivity has been designed. The maximum absorption in the transverse magnetic (TM)-polarized light exceeds 99.6% at 800–1000 nm. The maximum absorption in the transverse electric (TE)-polarized light exceeds 98.9% at 1500–1800 nm, and the peak absorption is more than 84.3% at 1800–2200 nm using finite-difference time-domain methods. By modifying various structural parameters, the absorption of the absorber could be separately shifted in a wide wavelength region. In addition, the designed absorber maintains good performance at large angles of incidence. This structure can be applied to other hybrid perovskite materials by simply changing the structural parameters. These results present a huge potential for applications based on metamaterial absorbers, such as infrared polarization imaging, selective spectral detection, near-infrared sensing, and polarization multiplexing.

Published: August 2023

Abstract
This research investigates the reduction in weight of hip implant by the application of parametric and non-parametric optimization techniques. Orthopaedic hip implants can be made from metals, ceramics, composites, or metallic alloys and are generally solid structures. The stiffness of orthopaedic hip implant is a pertaining problem when implanted in the human body as Hip implant are stiffer than bone material and causes stress shielding. This results in bone weakening which causes osteoporosis. Reduction in mass of femur stem results in stiffness reduction of femur stem. Non-Parametric topology optimization results in 34.9% mass reduction and parametric optimization based on Central Composite Design technique in Design of Experiments (DoE) uses hole diameters as parameters and performs structural optimization that results in 22% mass reduction.
Conformable packaging of a soft pressure sensor for tactile perception
Authors: Das Subham , Bhattacharjee Mitradip , Thiyagarajan Karthick , Kodagoda Sarath 
Published: August 2023

Abstract
Humans can perceive surface properties of an unfamiliar object without relying solely on vision. One way to achieve it is by physically touching the object. This human-inspired tactile perception is a complementary skill for robotic tactile perception. Robot perception depends on the informational quality of the tactile sensor; thus, packaging sensors and integrating them with robots plays a crucial role. In this work, we investigate the influence of conformable packaging designs on soft polydimethylsiloxane-based flexible pressure sensors that work in a variety of surface conditions and load levels. Four different 3D printed packaging designs capable of maintaining sensor trends have been developed. The low detection limits of 0.7 kPa and 0.1 kPa in the piezoresistive and piezocapacitive sensors, respectively, remain unaffected, and a performance variation as low as 30% is observed. Coefficient of variation and sensitivity studies have also been performed. Limit tests show that the designs can handle large forces ranging from 500 N to more than a 1000 N. Lastly, a qualitative study was performed, which covered prospective use-case scenarios as well as the advantages and downsides of each sensor casing design. Overall, the findings indicate that each sensor casing is distinct and best suited for tactile perception when interacting with objects, depending on surface properties.
A metasurface integrated shared aperture antenna for Sub-6 GHz applications
Authors: Das Priyanka , Rao Dhulipalla Venkata , BTP Madhav 
Published: August 2023

Abstract
A shared aperture antenna resonating at two sub-6 GHz fRequencies with frequency ratio 1.4 is proposed. A hybrid metasurface constituting two different types of band-stop FSS unit cells resonating at the same frequencies as that of the antenna is placed below it for simultaneous 4 dB gain enhancement of each antenna element at the resonant frequencies. Isolation of more than 35 dB is obtained in both the frequency bands. Equivalent circuit models of the bandstop FSSs have been proposed to explain their physical operation. The two antenna elements have been fed differently for minimising the isolation between them. The first antenna has a CPW feed line. The second antenna has a microstrip feed line. Compared to other existing works, the proposed design is compact and low profile having an aperture size of 50 mm by 52 mm, which makes it suitable for applications of dual sub-6 5 G frequency bands 3–4 GHz and 4.9–5.4 GHz. A prototype of the proposed shared aperture antenna integrated with the hybrid metasurface has been fabricated and measured as a proof of concept. Measured results are in close agreement with the full-wave simulated results.
Investigation of the vibration behavior of nano piezoelectric rod using surface effects and non-local elasticity theory

Published: August 2023

Abstract
Due to the importance of the analysis of piezoelectric nanorods and the different conditions they are exposed to in engineering problems, in this research, for the first time, both nonlocal elasticity theory and surface energy theory have been used simultaneously to model a piezoelectric nanorod. The natural frequency values of the system have been extracted using the Galerkin weighted residual method. By applying an external excitation voltage, the forced vibrations of nonlocal nanorods with surface effects are presented. The results are reported for different vibrational modes, and the impact of different parameters such as dimensions, nonlocal parameters, and surface effects are investigated. The results of this study prove that the nonlocal elastic theory is more effective than the surface energy theory on the vibration behavior of piezoelectric nanorods. Also, the effect of piezoelectric properties is strengthened due to the nanoscale of the rods.
Not choosing pathology: An essay-based survey of first-year clinical residents
Authors: Borbat Artyom , Novikova Tatiana , Yaroslavtsev Maxim , Bychkov Andrey 
Published: August 2023

Abstract

Objectives
Health care systems worldwide are facing a shortage in the pathology workforce that could negatively affect health care services, particularly oncology. To address this potential shortfall, the pathology community must identify the reasons why graduating students are not choosing pathology as a specialty.

Methods
We analyzed 226 free-text essay responses submitted by nonpathology residents at a teaching hospital. We used a general inductive approach and quantitative analysis to identify the barriers that prevent medical college graduates from choosing pathology as a specialty.

Results
Residents at our institution view pathology similar to residents from other countries, with the main obstacles to choosing pathology as a specialty being a perception that it lacks practical application to patient care or provides “no real help” and has a lack of patient interaction. In Russia specifically, there is a focus on the perceived negative aspects of autopsy as a barrier to selecting pathology. Less significant factors that may be based more on stereotypes than reality include the expectation that the work is not engaging, the emotional burden, and the occupational risks.

Conclusions
For medical students who place less importance on patient interaction, addressing these secondary factors could help select potential pathologists during students’ undergraduate years.
Supporting Relational, Trauma-Informed Social Care Work with Autistic Adults: Evaluation of a Reflective Supervision Group Pilot
Authors: Hallinan Patrick , McMahon Aisling 
Published: August 2023

Abstract
There is a growing body of literature highlighting the need for reflective supervision to support the often complex and challenging practice of social care workers. The current study aimed to explore an Irish social care team’s experience of a pilot reflective supervision group. The study participants were six male social care workers supporting autistic adults in the community. The team met for four one-monthly group supervision sessions, facilitated by an external supervisor. A reflective, relational approach was taken to the supervisory work, using role-play, free association and the Seven-Eyed model of supervision. At the end of the four-month pilot, participants completed a brief questionnaire to evaluate the supervision group experience. Thematic analysis of the participants’ open responses revealed the following themes: (i) increased insight/empathy; (ii) experiential learning; (iii) enhanced awareness/skills in relational practice; (iv) personal resilience; (v) team resilience; and (vi) emotional challenges. The study results suggest the potential importance of reflective supervision in boosting resilience, motivation and emotional insight when supporting people with unique relational needs.
A Sociological Reading of Statutory Social Work and Irish Corporate Governmentality: On the Death of Creativity
Authors: Flynn Susan , Whelan Joe 
Published: August 2023

Abstract
The corporate and neo-liberal governance of Irish social work, and a strangle-hold of legal-rational reasoning on the profession, has led statutory social work to be increasingly alienated from its traditional commitment to radical change in the pursuit of true social justice. Whilst this case has already been made, we set out to extend debates around an ‘epistemic schism’ in social work through a sociological critique of creativity. The demise of creativity arguably lies in the fettering of social work by corporate state entities, increasingly prescriptive governmental law and policy and a degree of deliberate deformation of social work through the health and social care regulator CORU. We argue that as the artistry of creative practice increasingly now comes under assault through proceduralisation, corporate governance and risk aversion, any remaining residuals of creativity also come to be repackaged and misappropriated in the form of ‘professional discretion’. What is at stake in the death of creativity is the death of anything surplus and exceptional to that which social workers are mandated to do. Moreover, we propose that without creativity, social workers can no longer fulfil the profession’s ideological goal of dismantling social injustice at a wider societal level.
