Monetizing Social Life Cycle Assessment (SLCA): A Case Study in SMEs Tapioca Industry in Lampung, Indonesia
Authors: Yosep Yosep , Mulkhan Unang , Hasanudin Udin , Agustina Iryani Dewi
Published: March 2024

To verify the responsible and sustainable functioning of circular economy (CE), assessing the sustainability of CE methods is essential. The consistent absence of a social aspect within the CE has been a recurring topic in research. This paper aims to pinpoint social-benefit aspects that are quantifiable in monetary values and investigate how attributing monetary significance to these elements can enhance the evaluation of social sustainability, leading to more informed decision-making processes. The methodology involves both quantitative and qualitative research methods. A quantitative research study was initiated in February 2023. Two approaches were used for sample selection. First, a case study approach was applied to select a specific SME within the tapioca industry. Survey interviews with workers follow the second step. This study also incorporates qualitative methods like literature review and interviews with key informants (cassava and social experts, government officials, and business owners) in April 2023. This research utilized descriptive analysis as a diagnostic tool, offering valuable insights. Challenges in monetizing social factors are discussed, highlighting the need for standardized frameworks, transparency, and stakeholder engagement. The paper also provides a practical example of monetizing social aspects within a small and medium-sized enterprise (SME) tapioca industry to address issues such as gender wage gaps, worker safety, and community engagement. The findings suggest that the costs of monetizing social aspects may outweigh the benefits in certain cases, calling for a reassessment of practices to ensure a more equitable and sustainable approach to social responsibility. Integrating social factors into assessments improves decision-making processes and stakeholder engagement, ultimately leading to more socially responsible decisions.

Authors: Chaiyaraksa Chompoonut , Sangworn Navapat
Published: March 2024

The focus of this study was to explore how various fertilizers influence the movement of cadmium in soil treated with biochar. The research utilized a strong acid sandy loam soil from Chanthaburi Province, naturally rich in organic matter with moderate cation exchange capacity and low nitrogen, potassium, phosphorus, sulfate, salinity and chloride levels. The soil was purposely contaminated with 50 mg kg-1 of cadmium and treated with biochar derived from water hyacinth through pyrolysis at 450°C for an hour. This biochar displayed moderate alkalinity, high organic matter, phosphorus, potassium, and cation exchange capacity, but low nitrogen content. Analytical techniques like Scanning Electron Microscopy and Fourier-Transform Infrared Spectroscopy were employed to study the surface characteristics of the biochar. The cadmium adding soil was blended with 10% biochar and various chemical fertilizers at a 0.04% ratio. Diethylenetriamine pentaacetate (DTPA) extraction was used to assess the bioavailability of cadmium to plants in the soil, while sequential extraction was conducted to identify the different forms of cadmium present in the soil. The study revealed distinct effects of different fertilizers on cadmium mobility. Fertilizers like 46-0-0 and 0-3-0 caused a transformation of cadmium from stable to less stable forms, increasing the bioavailability of cadmium to plants. Conversely, fertilizers such as 15-15-15, 0-0-50, 0-0-60, and 0-52-34 shifted cadmium from less stable to more stable forms, resulting in decreased cadmium extracted by DTPA. Other fertilizers showed no significant impact on cadmium mobility in the soil. A stepwise linear regression analysis highlighted that nitrogen content, potassium content, and electrical conductivity were influential factors affecting cadmium mobility.

Authors: Luther Siri , Vassanadumrongdee Sujitra
Published: March 2024

Thailand faces significant plastic waste management challenges. Around 2018-2019, a growing number of green retail shops started emerging in Thailand, offering products and services that eliminate or reduce the consumption of single-use plastics (SUPs). This paper intends to explore green retail as a niche in the Thai socio-technical system of SUPs. It aims to understand the socio-technical system’s current state, identify niche dynamics and momentum, illustrate key regime trajectories, and highlight policy levers. The study uses secondary data from academic articles and policy documentation, along with primary data from interviews with 20 Thai green retail founders conducted between 2020 and 2022, for thematic and content analysis. Findings suggest that the green retail niche has started establishing network, institutional and technological anchoring within the regime despite the disruptive impact of the COVID-19 crisis. Green retailers are committed to the development of their business models, but require support. The research suggests enhancing network formation and skills development within the niche, increasing access to financial resources, and establishing green financing options. It also suggests drawing links to more established niches and setting up incubation and acceleration programs for sustainability-minded small and medium enterprises (SMEs), thereby supporting their growth. Beyond the Thai context, this paper may be relevant for other countries and for evaluating sustainability niches in other sectors.

Published: March 2024

In the realization of further miniaturization at scales of 10 nm and below in semiconductor devices, it is essential to create new resist designs, such as hybrid inorganic-organic resist materials for ionizing radiation, in order to clarify the effect the structure of metal resist on resist performance. In this study, some hybrid inorganic-organic resist materials known as metal-oxo clusters were synthesized, and their lithographic characteristics were investigated to clarify the relationship between resist performance, such as sensitivity, resolution, and their absorption coefficient or cross section, and the density of their elements by using EUV and electron-beam (EB) exposure. Our results indicated that the sensitivity in Hf-based oxo clusters was higher than that of Ti-based and Zr-based oxo clusters in both EB and EUV exposure. Although the exposure dose was not optimized, the patterns of Ti-based, Zr-based, and Hf-based oxo clusters showed 100, 50, and 32 nm line-and-space patterns at doses of 250, 80, and 25 μC cm−2, respectively. We clarified that it is very important for new resist designs such as hybrid inorganic-organic resists to increase the photo-absorption cross section and density of elements for EUV and EB without degradation of film quality. In addition, the size and homogeneity of the building blocks and film quality are very important for the resist performance of hybrid inorganic-organic resist materials. Furthermore, it is clarified that the etch durability of metal-oxo clusters is higher than conventional resist materials, and this is much increased by annealing them at 800 °C.

We conducted research on the integration technology of a spin transfer torque-based magnetoresistive random access memory (STT-MRAM) cell (one transistor, one magnetic tunnel junction – 1T-1MTJ) on an 8-inch process platform. By combining a 0.5 μm CMOS front end of line process and STT-MTJ back end of line process, a 1T-1MTJ device with an MTJ of approximately 80 nm is realized. The Resistance(R)-magnetic field(H) measurement reveals a coercive force of approximately 450 Oe for the MTJ. Nevertheless, the 1T-1MTJ device exhibits a critical switching current of 4.7 μA (from high to low resistance state) and 17.9 μA (from low to high resistance state), accompanied by corresponding critical switching voltages of 0.05 V and 0.16 V, respectively, which is extremely low in an STT-MRAM with dual CoFeB/MgO interface free layer. Our findings demonstrate the potential for application in ultra-low-power portable mobile devices and embedded systems.

Stroke adalah penyebab utama penyakit serebrovaskular (CVD) dan merupakan penyebab kematian dan kecacatan yang cukup besar dalam masyarakat. Sekitar 80-85% dari seluruh kasus stroke disebabkan oleh iskemik. Faktor genetika memainkan peran penting dalam stroke yang terjadi lebih awal. Riwayat stroke dalam keluarga dikaitkan dengan prevalensi dan kejadian stroke yang lebih tinggi. Hingga saat ini, penelitian mengenai stroke iskemik masih terbatas pada pengidentifikasian variasi gen yang mempengaruhi, namun belum menghasilkan laporan yang secara spesifik menunjukkan variasi gen mana yang paling signifikan dalam menyebabkan stroke iskemik, terutama yang bersifat missense/nonsense. Oleh karena itu, pada penelitian ini digunakan database genomik dalam menganalisis bioinformatik untuk mengidentifikasi variasi gen yang memiliki korelasi paling kuat dengan stroke iskemik. Peneliti memanfaatkan sejumlah database, termasuk katalog GWAS, katalog PheWAS, HaploReg (v41.), dan portal GTEx. Hasil penelitian menunjukkan bahwa gen GCKR, ALDH2, dan F5 terkait secara signifikan dengan stroke iskemik, serta menunjukkan tingkat ekspresi yang tinggi pada beberapa jenis jaringan seperti hati, adiposa subkutan, ovarium, dan seluruh darah. Variasi gen berdasarkan frekuensi varian alel (rs1260326, rs671, rs6025) terkait stroke iskemik menunjukkan ekspresi jaringan tertinggi di liver. Penelitian ini menekankan pada penggabungan database genomik dan analisis bioinformatik yang mampu mengidentifikasi variasi gen yang memiliki peran penting dalam patogenesis stroke iskemik, terutama yang bersifat missense/nonsense. Peneliti merekomendasikan agar penelitian berikutnya memfokuskan validasi klinis variasi gen tersebut, terutama pada populasi Indonesia.

Authors: Pankov V.P.
Published: March 2024

Structural changes in alloys and coatings of turbine blades of aviation gas turbine engines during their operation under the influence of high temperature and stress are considered. It is shown that the cause of the appearance of thermal fatigue cracks in the coatings of turbine blades is the discrepancy of the acting stresses on the blade to the coating parameters: aluminum content, thickness, and its strength. A heat-resistant TP for turbine blades of GTE has been developed, consisting of layers, each of which has markedly different physical, thermal, and mechanical properties, creating an essentially complex coating structure.

Hypertension is high blood pressure of a long duration with blood pressure exceeding ≥ 140/90 mmHg, in general normal blood pressure is 120/80 mmHg. Symptoms that appear in hypertension are headaches, nausea, fatigue, vomiting, shortness of breath, anxiety, blurred vision which occurs due to damage to the brain, eyes, heart and kidneys. Many people do not fully understand the symptoms of hypertension. With the target organ in the brain being stroke, hypertension is the main cause of stroke which carries a high death rate. Hypertension is an important factor that triggers non-communicable diseases such as heart disease. Hamlet I Sidodadi Village receives a monthly report from the local health service's health research that hypertension is the biggest disease problem. This extension education began with a location survey in Sidodadi Village, Sibiru-Biru District, Deli Serdang Regency, so that data was obtained on 232 KK. And the results of educational outreach activities through discussions and questions and answers of ongoing outreach activities, it was found that 57 residents or 95% experienced an increase in hypertension and how to prevent hypertension. It was obtained from the results of the counseling that the occurrence of hypertension was caused by 3 main factors, namely that the dominant residents of Sidodadi Village, Sibiru-Biru District had a smoking habit, there were still many residents who consumed excessive salt, and the dominant age of the residents was over 40 years, classified as susceptible to hypertension.

In-house C massecuite reheater: a successful development for Le Gol sugar factory
Authors: Rivière Julien , Cadarsi Marc , Payet Jean-Raymond , Roussel Camille
Published: March 2024

Prior to 2020, due to an aging C massecuite reheater, the Le Gol sugar factory had issues with sugar quality (foreign particles) and back-end factory maintenance (weekly damage to centrifugal screens). Thus, a new reheater was required and was an opportunity to improve C molasses exhaustion. A commercial design was first considered but without a guarantee of efficiency improvement. An in-house reheater was designed and manufactured based on in-house skills that included maintenance and production teams. Several digital simulations enabled the investigation of tube layout, fin and partition designs, massecuite and water flows, and the need for thermal insulation. Raw materials for tubes and fins were chosen depending on massecuite composition, and a specific steel (Duplex stainless steel) seemed to be the most suitable. As the reheater shell was still in good condition, it was reused, and the new heating elements (provided by an external service but based on the in-house design) were implemented. Instrumentation and process control were improved, enabling fine-tuning of the steam consumption and improved C molasses exhaustion. The new reheater has been operating since the 2020 crop season. Results are even better than expected, and C molasses exhaustion has improved. There are no longer breakdowns due to screen damage. Maintenance costs are reduced as, for example, strainers have to be cleaned once a week instead of twice a day. Thanks to a better heat transfer, the target temperature of 57 °C for the outlet massecuite is achieved and maintained faster, and the inlet water only needs to be at 58°C (compared to 62 °C previously and even then, the target temperature wasn't achieved.) This approach promotes teamwork and is gratifying for co-workers. Moreover, all this development was successfully done during the first period of the Covid pandemic, showing Le Gol staff’s great adaptability and personal involvement.
