Authors: Putra Alfian , Rihayat Teuku , Aidy Nurhanifa 
Published: August 2023

Penelitian adsorpsi dari bahan alam telah banyak dilakukan dari berbagai bahan baku seperti ampas tebu, ampas kopi, bentonit dan lainnya. Namun persyaratan mekanis dan pengolahan dari berbagai aplikasi belum dapat dipenuhi. Pada studi ini telah dilakukan pengolahan adsorben berbahan kaolin menggunakan teknologi ultasonik untuk meningkatkan daya serapnya untuk mereduksi logam dalam air dengan cara memodifikasi kaolin dengan surfaktan anionik dan diiradiasi ultraonik. Tujuannya adalah mengoptimalisasi penyerapan logam yang lebih sepesifik dalam menyerap logam Fe dan Mg dalam air menggunakan kaolin yang telah dimodifikasi. Kaolin dihaluskan sampai dengan 100 mesh dan dicampurkan dengan surfaktan anioinik sebanyak 45%, dari berat total adsorben yaitu 200 gram. Proses adsorpsi dilakukan menggunakan kaolin modifikasi surfaktan dan tanpa modifikasi surfaktan dengan memvariasikan waktu iradiasi yaitu 5, 10, 15, 30, 50 dan 80 menit pada suhu 55 °C. Konsentrasi logam diukur menggunakan Atomic Absortion Spectrofotometers (AAS) serta dilakukan perhitungan kinetika adsorbsi. Hasil penelitian menunjukkan bahwa efisiensi penyisihan tertinggi terjadi pada kaolin yang dimodifikasi dengan surfaktan anionik. Hasil yang paling signifikan yaitu untuk Fe efisiensi penyisihannya mencapai 72,81 % pada waktu iradiasi 5 menit, sedangkan untuk Mg efisiensi penyisihannya mencapai 65,1% pada waktu iradiasi 5 menit.

Authors: Fengmei Zou 
Published: August 2023

This paper reports the knowledge and practice of self-regulation of English teachers in public primary and secondary schools in South-East China. The data were collected from multiple classroom observations of and in-depth interviews with two English language teachers working in Chinese schools. This study reported that despite limited knowledge of Self-regulated learning teachers’ classroom practices reflected an extensive use of SRL strategies positively impacting students’ learning engagment. However, the workload and the traditional grade-focused assessment systems influenced teachers’ consideration of self and their students’ learning motivation, metacognition, and cognition. These findings indicate a need to strengthen English teachers’ metacognition, cognition and motivational-emotional regulation to support student learning.

Clients' perceptions of nurse self-disclosure of previous personal experience with depression on the therapeutic relationship: a qualitative descriptive study
Authors: DeSanti Michelle 
Published: August 2023

<p>There is a paucity of literature on nurse self-disclosure. The purpose of this study was to describe clients’ perceptions of nurse self-disclosure of personal lived experience with depression in the therapeutic relationship. This study employed a qualitative descriptive design using clinical vignettes to obtain the perceptions of nurse self-disclosure of lived experience with depression from fifteen participants. Three themes emerged from the results: ‘Experiencing self-disclosure in a context that creates trust’, ‘Creating connection through understanding and empathy’, and ‘Feeling hopeful that recovery is possible’. A unique finding of this study was that participants’ perceptions of self-disclosure varied with the level of intimacy of the disclosure. This study offers preliminary implications regarding how self-disclosure of lived experience with depression may be adopted in clinical nursing practice. Implications for future practice, policy, research, theory and education are also discussed.</p>
The Integration of Human Factors to Warehousing and Manual Order Picking Operations
Authors: Setayesh Azin 
Published: August 2023

<p>Human Factors (HF) identified as the main concern of studies since poor HF and system design interaction has a negative impact on quality, error occurrence, system performance, and worker’s well-being. This dissertation takes literature review and sensitivity analysis to assess human- system errors by focusing on: 1) finding the most suitable model to estimate human-system errors, 2) identifying failure modes causing human-system errors, 3) creating a tool that capable of identifying the source of pick errors and degraded quality at the initial stage of a design, 4) evaluating the usability, functionality, and usefulness of the developed tool. The most common Human Reliability Assessment (HRA) models were studied to identify the most suitable model to estimate human error probability (HEP) in various contexts. The qualitative and quantitative analysis among the most common HRA models showed that these models are suffering from lack of guideline on Performance Indicating Factors (PIFs) selection and multiplier values allocation. Hence, a need for creating and validating new empirically based models in different sectors were recognized. Therefore, the focus of the research study was changed from finding a suitable model to determining the source of errors in manual order picking operation. The developed Warehouse Design Error Prevention (WDEP) checklist tool integrated HF aspects to both Order Picking (OP) design elements and warehouse management elements based on the identified failure modes from literature and field studies as elaborated in chapter 3 of this dissertation. Tool usability, functionality, and usefulness were evaluated through the survey study and qualitative interviews. The outcome of the user evaluation found the created tool useful, functional, and useable both at the initial stage of a design as well as during process improvement process. These dissertation findings illustrate the need for developing HF measures that contribute to pick errors and optimize OP system design strategies concerning HF demands by creating and validating the error prevention checklist tool. </p>
Real-Time Optimization of Production Scheduling: Strategies, Models, and Algorithms
Authors: Ghaleb Mageed 
Published: August 2023

<p>In practice, manufacturing systems are highly dynamic and continuously facing unexpected events and interruptions. This puts production managers in charge of making frequent updates to the ongoing plans and schedules to cope with these changes. This is done by adopting different scheduling strategies and optimization models. Despite several attempts in the literature, the need for models that can minimize the effect of changes (i.e., stochastic and robust models) or react to them using real-time information (i.e., real- time optimization models) is still felt. </p>
<p>This dissertation includes three main contributions with different optimization models and heuristic algorithms that can help managers deal with different unexpected events and interruptions on the shop floor. In the first contribution (Chapter 2), the case of stochastic deterioration-based failures in a single machine production system is considered. The machine’s degradation is modeled as a multi-state system. The obtained formulations are then integrated into an optimization model that jointly optimizes the production sequences, machine inspections, and condition-based maintenance actions. The results showed an average improvement of about 35% in total expected costs when information about the machine’s degradation level was used. </p>
<p>In the second contribution (Chapter 3), the case of unexpected new job arrivals and random machine breakdowns in a flexible job shop production environment is considered. The effect of random machine breakdowns on the processing durations is formulated and then integrated into a dynamic optimization model. The proposed model investigates how real-time updates can be utilized to improve scheduling decisions based on unexpected arrivals, the availability of machines (downtimes and recovery times), and the completion times of operations. </p>
<p>Finally, in Chapter 4, the case of integrating production scheduling and condition-based preventive maintenance (PM) planning in a flexible job shop production system is addressed. The study considers the case of stochastic machine degradation, random machine breakdowns, minimal repairs, condition-based PM, due date changes, and new job arrivals. The reliability of machines is modeled as a multi-state system, in which the obtained formulations are incorporated into an integrated dynamic optimization model. The developed model aims to study the effects of different RTS policies on each of the considered cases and empirically quantify the potential benefits of using real-time information to enhance scheduling decisions. </p>

Published: August 2023

The use of banana leaf ash extract (BLAE) as a replacement of Kosaric medium (KM) to grow spirulina (Spirulina platensis) was investigated. KM was partially replaced with more affordable and locally available BLAE at 0, 10, 30, 50, and 70% concentrations. The spirulina was grown for 18 days at room temperature in the experimental media with artificial lighting and aeration. By replacing KM with BLAE, the 30% replacement produced the highest biomass of S. platensis. It was observed that replacing of KM by 30% with BLAE produced biomass of 1.22 g/L, which was similar to that of 1.33 g/L with control (P <0.05). However, replacing more than 50% KM by BLAE failed to promote growth relative to the control. Moreover, chlorophyll a concentrations in the control were found comparable in up to 30% of BLAE concentrations. Protein, lipid, and fiber contents of S. platensis were found to be 57.67 ± 0.58, 11.59 ± 0.28, and 7.35 ± 0.37%, respectively, in 30% replacement of KM, compared to corresponding values of 58.02 ± 1.16, 12.25 ± 0.39, and 7.53 ± 0.32%, respectively, in control KM. At the 50% KM replacement level, these values dropped to 52.65 ± 0.98, 9.97 ± 0.51, and 7.25 ± 0.29%, respectively. In conclusion, cultivation of S. platensis with BLAE up to 30% replacement of KM may be viable without undue effect on the plant’s growth, pigmentation, or biochemical makeup.
