Perkembangan teknologi yang begitu pesat, guru dituntut untuk lebih kreatif dan mengembangkan keterampilannya dalam membuat media pembelajaran untuk membantu tingkat pemahaman siswa dalam mencapai tujuan pembelajaran. Sayangnya, berdasarkan hasil observasi, modul yang diberikan guru Mata Pelajaran Pemrograman Dasar SMK Negeri 48 Jakarta, ditemukan bahwa media pembelajaran yang digunakan dalam Mata Pelajaran Pemrograman Dasar khususnya materi flowchart masih kurang baik dikarenakan modul dan power point yang biasa digunakan mengandung banyak teks sehingga lebih lama untuk diserap dan dipahami siswa. Berdasarkan penelitian yang relevan, media pembelajaran berupa video berbasis motion graphic dipilih karena kaya akan animasi dan illustrasi yang baik yang dibutuhkan untuk membantu siswa agar lebih memahami materi pelajaran Pemrograman Dasar dan agar materi yang disampaikan dapat lebih mudah diingat. Sebagai solusi dari masalah tersebut, dibuatlah media pembelajaran video motion graphic yang dikembangkan dengan metode Multimedia Development Live Cycle (MDLC), yang di dalamnya terdapat tahap pengonsepan, perancangan, pengumpulan data, produksi, evaluasi, dan pendistribusian dengan menerapkan 3 prinsip multimedia pembelajaran yaitu prinsip koherensi, redudansi, dan personalisasi. Dalam media pembelajaran ini tidak akan mencantumkan gambar, teks, animasi yang dirasa tidak penting dan tidak ada kaitannya dengan materi (prinsip koherensi). Selain itu juga tidak akan menyatukan narasi dan animasi dengan teks yang panjang, karena penjelasan dengan narasi akan lebih mudah dimengerti dibanding animasi dan teks yang panjang (prinsip redudansi). Prinsip personalisasi dengan gaya penyampaian dengan bahasa yang biasa digunakan sehari-hari dan tidak kaku, sehingga dapat lebih mudah dipahami (prinsip personalisasi). Produk media pembelajaran yang dihasilkan memiliki validitas tinggi karena sudah melalui proses uji validitas oleh tim ahli dan uji coba lapangan. Produk yang dihasilkan berupa video pembelajaran berbasis motion graphic yang memiliki tingkat kelayakan 97,67% yang masuk ke dalam kategori sangat baik.

Successful Execution of Hydraulic Fracturing via a Multi-Stage Ball Drop Completion to Extend Platform Life and Access Previously Untouched Reserves in a Challenging Operational Environment – A Central North Sea Case Study

Abstract
In 2019 the Armada hub was evaluated for drillable targets to exploit previously untouched reserves and extend the life of the platform. Seymour Horst oilfield, the most eastern of fields served by Armada, was discovered in 1983, and appraised the same year. These wells were drill stem tested in multiple zones, but all had low production rates. Reservoir simulation work estimated that drilling and completing a long horizontal well in Seymour Horst's upper and middle Skagerrak sands followed by multi-stage hydraulic fracturing treatments to overcome reservoir compartmentalization and low vertical permeability would bring the well to economic rates. Well 22/5b-A14 was sanctioned and drilled in 2019/2020.
Execution of hydraulic fracturing campaigns in long horizontal wells in the challenging North Sea environment is complex, with great emphasis on operations efficiency. Considerable time was put towards each element of the well construction and job design, including the modelling of reservoir characteristics critical for fracturing, multi-stage fracturing completion design, fracturing materials, management of resources onsite during execution, and the design of the CT string to be used as contingency. This paper describes the detailed planning process and utilization of a combination of new North Sea technologies and operational techniques to successfully execute the campaign with large proppant volumes in the high temperature reservoir, in a challenging offshore environment, in an efficient and cost effective manner.
Over 40,000 Bbl. of clean fluid and 2,500,000 lbs of 16/20 resin coated ceramic proppant with ~7.5% of that volume being infused with scale inhibitor, was pumped into the well from the dedicated stimulation vessel. The campaign was executed over the winter months in 2020, and therefore was subjected to waiting on weather delays. As a result, the vessel operating efficiency was 11% vs the estimated 22%. However, the use of the ball actuated multi-stage system eliminated five of the seven intervention operations that would have been required in a conventional completion system between each stage, saving valuable rig time, and allowing the stimulation vessel to maximise the use of the operable weather windows. Further time savings were made through use of water bunkering operations, reducing the number of sailings required by the stimulation vessel to place such a large volume of fluid and proppant. Production rates, while initially lower than expected, remain sustained. There have been no issues with scale to this date.
Self-Degrading Particulates Improving Proppant Placement in High Temperature-High Permeable Sandstone Formation

Abstract
In proppant stimulation treatments, when high fluid leak-off and low fluid efficiency is encountered, typically the first measure taken in job redesign is to increase the PAD volume and pumping rate to mitigate fracture width reduction. These measures will adversely affect the job treatment cost and increase the water load on the formation. High fluid leak-off and low fluid efficiencies could be due to high permeability formation and/or presence of Natural Fractures (NF).
In an effort to prevent permanent formation or proppant pack damage, this paper discusses the use of self-degrading multiple particle sizes while pumping. When these particles were used, it allowed to successfully seal off the width near the fracture's tip, controlling excessive leak-off and improving proppant placement volume.
Permeability and NF could be identified during pre-frac injection tests; however, in some formations when diagnostic injection is conducted at lower rate, NF might not be easily identified and could be opened-up unexpectedly during main fracture treatment as long as the net pressure increases, leading into an uncontrolled leak-off, early flush or screen-out. A comprehensive well data analysis performed during design stage along with an effective diagnostic injection test before main treatment can identify low fluid efficiency. This paper presents results from extensive testing and application of self-degradable particulates as a leak-off material for the first time in the middle east.
The Novel approach of this method allowed for controlled stimulation operations with the opportunity of limiting the high leak-off. This would ultimately increase the chance of proppant placement and avoid screen-out scenarios.

Abstract
Development of the tight gas Khazzan Field in Sultanate of Oman has progressed through many years of extensive learning. Massive hydraulic fracturing operations became a key part of the completions in the Barik reservoir. Fracturing design was optimized with time, eventually achieving a fit-for-purpose fracturing design. However, when activities moved towards the south, increase in reservoir gross thickness was encountered, and implementation of the standard fracturing design led to increased number of screenouts.
Many parameters were examined to discover the root cause of the increased screenout rate, such as changes in pumping schedules, changed reservoir properties, fracture execution data, completion details, and many others. After the thorough analysis, it was found that lack of hydraulic width played the major role in most of the screenouts. Multiple solutions to resolve the lack of hydraulic width were considered: increase in gel loading, increase in pumping rate, optimizing pad volume, changing completion strategy, reducing job size, reducing proppant concentration, etc.
After thorough consideration, it was found that removing the larger proppant might be an optimum solution for this challenge. The standard fracturing design typically included 70% of smaller ceramic 20/40 and 30% of larger 16/30 ceramic proppant. Performed production analysis has shown that some reduction in fracture conductivity by removing 16/30 proppant will have minimum negative effect on well productivity in conditions of the tight gas Barik reservoir. The results of this change have exceeded expectations: screenout rate has declined from 38% to 0% while post-fracturing production has shown the same gas rates as those with larger proppant.
This paper shows how a simple but properly evaluated solution has regained the success of proppant fracturing operations in Sultanate of Oman.

Published: September 2023

Abstract
The main objective of this study is to present the findings of an assessment conducted on an unconventional vertical well, which aimed to acquire closure pressure estimates at multiple depth points, evaluate fracture height propagation at specific sections, identify fracture barriers, and relevant reservoir properties at different intervened sections. The subjected well passed through seven different sections, some of which were considered potential prolific targets while others were considered fracturing barriers. The first objective of the well was to acquire multiple closure pressure values at multiple depths that can later be used to calibrate stress models. To meet that objective, a diagnostic fracture injection test (DFIT) was conducted at the seven different sections with variable monitoring durations. Downhole memory gauges were installed to minimize uncertainties related to pressure fluctuations in surface gauges which could be attributed to day to night temperature variations. Out of the seven DFITs, closure pressure was estimated in two out of the seven sections. The second objective was to assess vertical fracture height growth in two of the most prolific sections, with a design objective of mimicking a single cluster in a horizontal lateral. To achieve that, a mini fracture at pre-determined pumping rates and volumes was pumped followed by three high resolution temperature (HRT) logs acquired at 2-hour gap intervals, yielding cool down and warm up profiles that reflect height growth. For both mini fractures pumped at the two sections, estimation of maximum fracture height was obtained. Overlapping results from both mini fracture tests indicated that the two sections did not interfere with each other. The novelty of this study lies in its implementation rarity in unconventional fields due to the uncommonness of vertical unconventional wells. The information gathered from this study provides key parameters for understanding fracture behavior in multiple vertical sections, which are essential in the design of stimulation operations and future decision-making processes.

Abstract
Conventional gravel pack provided robust sand control but with high skin and poor productivity for the last 3 decades. Recently, frac pack was revived with improvements in perforations, net pressure, tip screen out, and downhole equipment and was implemented in phase 1 development of D field in early 2020 to achieve high productivity and sand control. Initial phase of frac pack application saw challenges in designs and operations. Valuable lessons have been captured and implemented in the next phases in B field in late 2020 and in D field in 2022. Operation optimization resulted in simplification of the procedures, reduction of fluid volume injected, reducing in rig time and cost while maintaining the quality of frac pack. Real time decision which differs from initial plan had to be made during implementation to produce the best outcome.
Optimizations in procedures and chemical selections brought higher productivity while achieving effective sand control. Some frac pack were done without minifrac. Further optimization in the frac pack has been achieved by applying screenless frac pack with resin coated proppant for one well in D field and resulted in increase in well productivity and well completion cost reduction. Highly efficient operations were achieved through procedural improvement. Detrimental chemical additive in frac fluid has been identified and eliminated in the second phase wells. These efforts have contributed to achieve or exceed the production targets while providing robust sand and fine control as an effective downhole sand control completion.
This paper examines the challenges, offers improvement to make frac pack a viable solution to achieve field production objectives, and evaluates production performances across the phases.

Published: September 2023

Abstract
Background:
Patients with multiple myeloma are functionally immunosuppressed and when presenting with respiratory failure, pulmonary infections must always be considered. However, while rare, adverse effects of immunomodulating medications used in the treatment of multiple myeloma can also result in potentially life threatening respiratory failure, a distinction which has important treatment implications.
Case Presentation:
An 80-year-old male with recently diagnosed multiple myeloma undergoing treatment with lenalidomide presented with acute, rapidly progressive hypoxic respiratory failure ultimately requiring intubation and mechanical ventilatory support. Imaging revealed bilateral pulmonary opacities, however infectious workup was negative, and he was ultimately diagnosed with lenalidomide-induced interstitial pneumonitis, a rare but serious adverse effect of this medication. He was treated with drug discontinuation and steroids, and quickly recovered.
Conclusion:
Lenalidomide is an immunomodulating medication used in the treatment of multiple myeloma, and is associated with rare but serious cases of drug-induced interstitial pneumonitis. Thus, if a patient receiving lenalidomide develops shortness of breath and/or hypoxia, drug-induced pneumonitis must be on the differential. Permanent drug discontinuation with or without corticosteroids is the mainstay of treatment, and patients are often able to fully recover, underscoring the need for early recognition of this condition.

Abstract
In this study, cost-effective peroxymonosulfate (PMS) was used as an oxidant, and a Cu-Fe-Ni layered hydroxides/magnetic biochar composite (MBC/CuFeNi LDHs, MC-1 for short) was used as a catalyst to remove enrofloxacin (ENR), a high toxic pollutant identified in water. The layered structure and surface functional groups of the composite contributed to the degradation of ENR. More specific, 91.6% of ENR was degraded by MC-1&PMS system within 20 minutes. The superior performance of MC-1 was confirmed by characterization analysis and catalytic experiments. The catalytic system not only possessed good recycling performance, but also had excellent magnetic properties. In addition, the catalytic mechanism of the MC-1&PMS system was attributed primarily to the generation of hydroxyl (∙OH), but also the sulfate (SO4∙−), singlet oxygen (1O2) and superoxide radicals (∙O2−). Furthermore, a possible degradation pathway of ENR was proposed. This study provided a new insight for the design of heterogeneous carbon catalysts in advanced oxidation field.

Published: September 2023

Abstract
Background
Chronic obstructive pulmonary disease (COPD) is a serious chronic disease of the airways that affects many people worldwide and have limited treatment options. While small animal models provide a platform for therapeutic investigations into COPD, their deficiencies continue to impede clinical translation. Alternatively, as a large animal model, sheep have a respiratory system that is anatomically and physiologically similar to that of humans, which has provided validation for their use in airway disease research. The aim of this study was to better understand disease pathology in a large animal (sheep) experimental model of COPD.
Methods
COPD was induced in sheep following lung exposure to porcine elastase (PE) and repeated weekly lung exposures to lipopolysaccharide (LPS) over a period of 8 weeks. Bronchoalveolar fluid and blood samples were collected for immune analyses. Lung function was assessed and lung tissues were collected for histopathology and RNA sequencing.
Results
Lung neutrophil levels were elevated in response to repeated airway exposure to PE/LPS, accompanied by a significant decline in ventilation over time. Histological evidence of COPD-like disease changes included chronic inflammation with increased airway and tissue inflammation scores, together with significantly larger airway wall area measures, increased connective tissue deposition and dysregulated gene expression.
Conclusions
These studies demonstrate sustained chronic airway inflammation and pathophysiological lung changes in a sheep model of COPD, providing many similarities to that seen in COPD patients. This work opens a pathway for future translational studies using this unique large animal model of COPD, which will serve to bridge the gap between smaller animal models and humans.

Abstract
Background: Evidence suggests that risk factors for Alzheimer’s disease and related dementias (ADRD) are at least partially modifiable, and that lifestyle risk accumulates as we age. However, the prevalence and impact of lifestyle-related risk factors in young adulthood (i.e., 18-39 years) remain poorly understood, with some risk factors that are developed in early adulthood being difficult to remove and reverse at midlife. The Next Generation (NextGen) brain health survey is the first of its kind to be designed specifically for young adults, with the aim of exploring attitudes, understanding and exposure to ADRD risk and protective factors in this life stage.
Methods: The NextGen survey is an international, cross-sectional survey of young adults aged 18-39 years. The survey was developed in three phases with ongoing input from public advisors (i.e., young adults from Europe, North America, and Africa). First, we adapted items from existing literature for the target population. Second, we conducted focus groups with young adults to review the items and explore new themes. Third, we piloted the survey in an international network, including brain health researchers, clinicians, and advocacy groups. Feedback was integrated to create the finalized survey.
Discussion: The NextGen survey will be conducted online and made available to individuals aged 18-39 years internationally. Results will contribute new knowledge about young adults and ADRD risk exposure before mid-life, including much-needed evidence in populations that are traditionally under-represented in research. Findings will also help to identify mediators and modifiers of associations between knowledge, attitudes, and risk exposure, and provide the basis for comparison with middle-aged and older populations.
