Authors: Baniah Bidyut , Kunapareddy Divakar , Iyer Suresh S. , Kumar Rajeev , Naveen R.
Published: November 2023

The demand for pipeline integrity assessment is ever-increasing due to an ageing pipeline network, a need for maintaining safe pipelines along with a stringent industry regulation environment. Not all pipelines are piggable and the non-piggable pipelines are considered more challenging due to their limitations for assessment. Fortunately, the industry has provided with standards and codes related to Direct Assessment (DA) program, as an integrity validation tool, which is especially applicable for non-piggable pipelines.

DA is a process driven approach that involves understanding the history of each of the pipelines, conducting multiple aboveground surveys, performing software simulations related to liquid and solid hold up resulting in prediction of corrosion rates and eventually directly inspecting the pipelines to determine the extent of actual corrosion along with condition of the pipeline. These results are utilized for predicting the remaining life and providing a root cause analysis along with mitigation strategies for each pipeline.

Pipeline owner, Pipeline Infrastructure Limited (PIL) operates India’s single largest natural gas mainline of 48″ originating from Kakinada and terminating in Bharuch, covering a span of 1,375 km passing through five (5) states and known as the East West India pipeline. The mainline also comprises of various spurs and interconnections along its route which are considered non-piggable. Ten (10) of these non-piggable lines were proposed for code-compliant DA integrity assessment program as part of pipeline owner’s corporate mandate, keeping in mind the greater good of maintaining utmost safety at all times. The DA methodology was applied for evaluating External Corrosion (ECDA), Internal Corrosion (ICDA) and Stress Corrosion Cracking (SCCDA). These lines were commissioned in year 2009 to 2013 were located in the states of Andhra Pradesh (2 pipelines), Maharashtra (1 pipeline) and Gujarat (7 pipelines) and ranged in diameter from 10″ to 30″ with a length of 300 m to 28 kms.

This paper will discuss the findings and learnings of the turnkey DA program related to all the three (3) threats and results of the four (4) steps i.e., Pre-Assessment, Indirect Inspection, Direct Examination and Post Assessment. The pipeline owner was not only able to perform a code compliant integrity validation program for these non-piggable lines, but also customize a go forward action plan as applicable to each pipeline.
The internal structure of Eris inferred from its spin and orbit evolution
Authors: Nimmo Francis , Brown Michael E.
Published: November 2023

The large Kuiper Belt object Eris is tidally locked to its small companion Dysnomia. Recently obtained bounds on the mass of Dysnomia demonstrate that Eris must be unexpectedly dissipative for it to have despun over the age of the solar system. Here, we show that Eris must have differentiated into an ice shell and rocky core to explain the dissipation. We further demonstrate that Eris’s ice shell must be convecting to be sufficiently dissipative, which distinguishes it from Pluto’s conductive shell. The difference is likely due to Eris’s apparent depletion in volatiles compared with Pluto, perhaps as the result of a more energetic impact.
A metric for characterizing the arm nonuse workspace in poststroke individuals using a robot arm

Published: November 2023

An overreliance on the less-affected limb for functional tasks at the expense of the paretic limb and in spite of recovered capacity is an often-observed phenomenon in survivors of hemispheric stroke. The difference between capacity for use and actual spontaneous use is referred to as arm nonuse. Obtaining an ecologically valid evaluation of arm nonuse is challenging because it requires the observation of spontaneous arm choice for different tasks, which can easily be influenced by instructions, presumed expectations, and awareness that one is being tested. To better quantify arm nonuse, we developed the bimanual arm reaching test with a robot (BARTR) for quantitatively assessing arm nonuse in chronic stroke survivors. The BARTR is an instrument that uses a robot arm as a means of remote and unbiased data collection of nuanced spatial data for clinical evaluations of arm nonuse. This approach shows promise for determining the efficacy of interventions designed to reduce paretic arm nonuse and enhance functional recovery after stroke. We show that the BARTR satisfies the criteria of an appropriate metric for neurorehabilitative contexts: It is valid, reliable, and simple to use.

Published: November 2023

Monoterpenes are secondary metabolites of plants belonging to the terpenoid class of natural products. They are the most abundant components of essential oils that are generally considered to have various pharmacological properties. These compounds are reported to have antidiabetic effects in recent years. Due to nature’s complex biosynthetic machinery, they also exhibit a reasonable degree of structural complexity/diversity for further analysis in structure-activity studies. Therefore, monoterpenes as antidiabetic agents have been investigated by recent in vitro and in vivo studies extensively reported in the scientific literature and claimed by patent documents. The purpose of this survey is to provide a comprehensive and prospective review concerning the potential applications of monoterpenes in the treatment of diabetes. The data for this research were collected through the specialized databases PubMed, Scopus, Web of Science, and ScienceDirect between the years 2014 and 2022, as well as the patent databases EPO, WIPO, and USPTO. The research used 76 articles published in the leading journals in the field. The main effect observed was the antidiabetic activity of monoterpenes. This review showed that monoterpenes can be considered promising agents for prevention and/or treatment of diabetes as well as have a marked pharmaceutical potential for the development of bioproducts for therapeutics applications.
Effect of Surface Composition on Electrochemical Oxidation Reaction of Carbon Monoxide and Ethanol of PtxRh1−x Solid Solution Electrodes
Authors: Kien Nguyen Trung , Yara Haruki , Chiku Masanobu , Higuchi Eiji , Inoue Hiroshi
Published: November 2023

PtxRh1−x (x = 0.76, 0.54, and 0.27) solid solutions were prepared by arc-melting. For these solid solutions, the lattice constant was linearly related to the Pt content. The surface compositions of the solid solutions determined by X-ray photoelectron spectroscopy were quite similar to their bulk compositions estimated by energy dispersive X-ray spectroscopy. The CO-stripping voltammograms demonstrated that the onset potential of CO oxidation current density (Eonset) shifted negatively as the surface Pt content decreased, suggesting an increased CO-poisoning resistance. Linear sweep voltammograms of the solid solution electrodes in an Ar-saturated (1 M ethanol + 0.1 M HClO4) solution exhibited that the onset potentials of ethanol oxidation reaction (EOR) current for all solid solution electrodes were lower than of a Pt electrode, and Pt0.54Rh0.46 gave the highest specific activity (SA) of 312 μA·cm−2, which was about 1.8 and 2.5 times higher than the SAs of Pt and Rh, respectively. In situ infrared reflection-absorption spectra exhibited that the Pt0.54Rh0.46 electrode had the bands due to the linear-bonded CO on Pt and bridge-bonded CO on Rh as EOR intermediates around 0.2 V vs. the reversible hydrogen electrode, but the band due to the linear-bonded CO on Rh was not observed even at 0.6 V, suggesting that the existence of the adjacent Pt-Rh sites and the preferential formation of bridge-bonded CO on Rh accelerated the C-C bond cleavage and improved the EOR activity.

Published: November 2023

Background. The 3D T1W turbo field echo sequence is a standard imaging method for acquiring high-contrast images of the brain. However, the contrast-to-noise ratio (CNR) can be affected by the turbo factor, which could affect the delineation and segmentation of various structures in the brain and may consequently lead to misdiagnosis. This study is aimed at evaluating the effect of the turbo factor on image quality and volumetric measurement reproducibility in brain magnetic resonance imaging (MRI). Methods. Brain images of five healthy volunteers with no history of neurological diseases were acquired on a 1.5 T MRI scanner with varying turbo factors of 50, 100, 150, 200, and 225. The images were processed and analyzed with FreeSurfer. The influence of the TFE factor on image quality and reproducibility of brain volume measurements was investigated. Image quality metrics assessed included the signal-to-noise ratio (SNR) of white matter (WM), CNR between gray matter/white matter (GM/WM) and gray matter/cerebrospinal fluid (GM/CSF), and Euler number (EN). Moreover, structural brain volume measurements of WM, GM, and CSF were conducted. Results. Turbo factor 200 produced the best SNR (

median
=
17.01

) and GM/WM CNR (

median
=
2.29

), but turbo factor 100 offered the most reproducible SNR (

IQR
=
2.72

) and GM/WM CNR (

IQR
=
0.14

). Turbo factor 50 had the worst and the least reproducible SNR, whereas turbo factor 225 had the worst and the least reproducible GM/WM CNR. Turbo factor 200 again had the best GM/CSF CNR but offered the least reproducible GM/CSF CNR. Turbo factor 225 had the best performance on EN (-21), while turbo factor 200 was next to the most reproducible turbo factor on EN (11). The results showed that turbo factor 200 had the least data acquisition time, in addition to superior performance on SNR, GM/WM CNR, GM/CSF CNR, and good reproducibility characteristics on EN. Both image quality metrics and volumetric measurements did not vary significantly (

p
>
0.05

) with the range of turbo factors used in the study by one-way ANOVA analysis. Conclusion. Since no significant differences were observed in the performance of the turbo factors in terms of image quality and volume of brain structure, turbo factor 200 with a 74% acquisition time reduction was found to be optimal for brain MR imaging at 1.5 T.
Industrial Marine Fishing in the Face of Climate Change in Peru
Authors: Coayla Edelina , Bedón Ysabel , Rosales Tomás , Jiménez Luis
Published: November 2023

Peru’s industrial fishery centers on the Peruvian anchoveta (Engraulis ringens), which is highly productive due to the marine conditions of the Humboldt Current. However, like elsewhere, the country’s marine fishing industry is linked to climate change. The objective of this study is to analyze the relationship between industrial marine fishing and climate change in Peru. Correlation and linear regression methods were used. A key variable of climate change is the sea surface temperature (SST). The study found that in Peru during 1997-2020, the higher the SST, the lower the industrial fishing catch (

α
=
5
%

). There is also evidence of an inverse correlation between sea level and industrial catch; i.e., sea level rise would alter marine ecosystems. A positive correlation between landings of industrial marine fishing and exports for nonfood purposes was corroborated, especially fishmeal. The study concludes that the industrial Peruvian anchoveta catch is negatively affected by SST, fishing effort (search time in hours), and catch per unit of effort (CPUE). For the sustainability of Peru’s industrial fishery, climate change adaptation measures, such as a reduction of fishing effort and research on alternative production of fishmeal with unmodified natural inputs without or in combination with anchoveta, should be implemented. For the future, a change in fishing policies is required that replaces anchoveta for fishmeal with a warm-water marine species during strong El Niño events.

Introduction: Management of the neck in oral cavity squamous cell carcinoma (OCSCC) is essential to oncologic control and survival. The rates of lymph node metastasis (LNM) vary based on oral cavity tumor site and stage and influence treatment decisions. The aim of this paper was to describe clinical LNM for different tumor subsites and stages of surgically managed OCSCC. Methods: We conducted a retrospective analysis of 25,846 surgically managed OCSCC patients from the National Cancer Database (NCDB) stratified by tumor subsite and clinical T-stage. For cN + patients, rates of pathologic LNM and absence of pathologic LNM were determined. For cN0 patients, outcomes included the rates of elective neck dissection (END) and occult LNM and predictors of occult LNM determined by a multivariable logistic regression model. Results: A total of 25,846 patients (59.1% male, mean age 61.9 years) met inclusion criteria with primary tumor sites including oral tongue (50.8%), floor of mouth (21.2%), lower alveolus (7.6%), buccal mucosa (6.7%), retromolar area (4.9%), upper alveolus (3.6%), hard palate (2.7%), and mucosal lip (2.5%). Among all sites, clinical N+ rates increased with T-stage (8.9% T1, 28.0% T2, 51.6% T3, 52.5% T4); these trends were preserved across subsites. Among patients with cN + disease, the overall rate of concordant positive pathologic LNM was 80.1% and the rate of discordant negative pathologic LNM was 19.6%, which varied based on tumor site and stage. In the overall cohort of cN0 patients, 59.9% received END, and the percentage of patients receiving END increased with higher tumor stage. Occult LNM among those cN0 was found in 25.1% of END cases, with the highest rates in retromolar (28.8%) and oral tongue (27.5%) tumors. Multivariable regression demonstrated significantly increased rates of occult LNM for higher T stage (T2 OR: 2.1 [1.9–2.4]; T3 OR: 3.0 [2.5–3.7]; T4 OR: 2.7 [2.2–3.2]), positive margins (OR: 1.4 [1.2–1.7]), and positive lymphovascular invasion (OR: 5.1 [4.4–5.8]). Conclusions: Management of the neck in OCSCC should be tailored based on primary tumor factors and considered for early-stage tumors.

Authors: Mortiz Jo Niza B. , Digamon Jayson S.
Published: November 2023

Secondary school graduates entering tertiary education must possess the skills and knowledge to adapt rapidly to the ever-changing landscape of a knowledge-based economy. This study assessed the cognitive and non-cognitive college readiness levels of the 127 pioneering senior high school graduates of the Philippine K-12 Program enrolled as first-year college students in a private Higher Education Institution (HEI) in Northern Mindanao, Philippines. Data gathered for this descriptive research were collected using two standardized tests (OLSAT and 16PF). Results revealed that many students had a below-average cognitive level and average non-cognitive skills implying that they were not ready for the tertiary level cognitively but were college-prepared non-cognitively. It was concluded that assessing students' college readiness levels proved imperative to ensure that standards of the chosen programs are met vis-à-vis students' skills. The researchers recommend that Higher Education Institutions strengthen and institutionalize readiness assessment that will serve as a basis for bridging and remediation program for identified cognitively unprepared college students.

Published: November 2023

The study aimed to investigate the level of knowledge and attitudes towards environmental laws among Bachelor of Elementary Education (BEED) students. A quantitative research design was utilized, and the primary data-gathering tool was a survey questionnaire. The study discovered that the BEED students had a generally poor level of knowledge, but their attitudes toward environmental laws were positive. The outcomes showed that only a few students were concerned about the environment and supported environmental protection, and a majority of them did not practice positive behavior. Despite knowing the penalties for violating environmental laws in the Philippines and the procedures for reporting environmental violations, many students continued their bad practices. Only a small proportion of them exhibited positive behavior or practices that supported environmental protection. Therefore, the BEED students at DEBESMSCAT, Cawayan, Campus had an insufficient and incomplete understanding of the environmental laws in the Philippines. The findings of the study highlighted the need to enhance the environmental education curriculum in the BEED program to improve the student's knowledge and attitudes toward environmental laws. As the students' knowledge and attitudes towards environmental laws could significantly impact their behavior and practices, it was essential to strengthen their comprehension of environmental laws and their role in environmental protection. The study emphasized the responsibility of academic institutions in promoting environmental education among students to ensure that they became environmentally responsible citizens in the future.

Authors: Giner Rhogin V.
Published: November 2023

This study examines the learning opportunities and challenges faced by students at the Asian Institute of Maritime Studies (AIMS) in response to the sudden shift to online learning during the Covid-19 pandemic. AIMS, like many educational institutions in the Philippines, adapted to the new normal setting by implementing online learning with all its facets. While this setup opened up new opportunities for students, it also presented various challenges.

The research involved 337 AIMS students from the 2021-2022 academic year, using a descriptive-comparative design to assess differences in opportunities gained and challenges experienced. The participants were selected through a combination of purposive and random sampling. Data was collected using a standardized instrument consisting of three parts: profiling respondents, determining opportunities gained using the "Synchronous Online Teaching Observation Checklist" from the City University of New York (2020), and assessing challenges through the self-report online learning challenge questionnaire by Barrot et al. (2021), modified for the study. Statistical tools such as frequency, percentage, weighted mean, T-test, and ANOVA were utilized for data analysis.

Results indicated that students perceived opportunities in Assessment and Feedback, Student Engagement, Learning Environment, Time Management, and Instructional Design. On the other hand, they expressed neutrality towards challenges related to Technological Sufficiency, Student Isolation, Technological Complexity, Self-Regulation, and Learning Environment. Further analysis revealed significant differences in learning opportunities based on gender and program. Recommendations include providing platform usage training, offering specialized learning activities based on courses and programs, and ensuring gender-sensitive learning opportunities.

Authors: Cabasal Maria Celia , Escalona Jessa B.
Published: November 2023

This study focused on assessing the research capacity and capacity-building needs of faculty members and personnel at the Asian Institute of Maritime Studies (AIMS) to enhance the institution's research culture. The study revealed that AIMS has lagged in terms of research production. To overcome this challenge, the Center for Research and Institutional Development (CRID) at AIMS has developed research programs and training to cultivate a research-oriented environment.

Using a descriptive correlational design, the study involved 167 faculty members and personnel. Three domains were assessed: individual, team, and organization. A questionnaire comprising three parts was utilized for data collection. The first part aimed to gather respondents' profiles, while the second part contained statements pertaining to research capacity assessment in the three domains. The third part addressed research capacity-building needs and the available resources at AIMS.  The results indicated that respondents possessed a basic understanding and capabilities in research, as reflected in their average weighted mean scores. They also identified research funding, facilities and infrastructures, research training, and support for presentation and publication as vital components for successful research endeavors.

Furthermore, the study established a strong relationship between research capacity assessment and the need for funding, facilities/infrastructure, training, and presentation/publication support. Higher research capacity assessment scores correlated with greater capacity-building needs across the three domains. Consequently, the study recommended that the CRID office should assess the research-level capabilities of faculty members and personnel and provide targeted research training to address their specific needs.

Published: November 2023

The community needs assessment of three adopted barangays of the Asian Institute of Maritime Studies served as a guide for the Center for Outreach Extension Development in enhancing strategic plans and programs, and in preparing necessary resources and funds.

In assessing the needs of residents of the three adopted barangays, a descriptive-survey method was applied since it aims to gather the present conditions and situations of the barangays’ residents. The Community Needs Assessment survey instrument involves questions relevant to the subjects of the research and distributed to the respondents. Respondents are representative of each family in the three adopted community beneficiaries. In Barangay 13, there were 21 families; in Barangay Julugan IV, there were 24 families and in Barangay La Isla Bonita, there were 14 families. Convenience sampling was used and families living in the nearby vicinity of the Barangay Hall were the participants. From the result of the survey, most of them were high school graduates and unemployed. Likewise, participants cannot identify their own skills so the majority of the families lack a source of income, and this is a common problem within the three barangays. The suggested trainings that the respondents were willing to attend are training for electronic/ computer/cellphone repair, cooking, dressmaking, and practical electricity. The additional training to the existing program could help families to have a source of income or to be employed. Thus, the members of the adopted community could have a better standard of living through skills trainings.

Published: November 2023

This study aimed to assess the perceived credit risk associated with microfinance loans among micro-enterprise businesses. It had three primary objectives: first, to profile the respondents based on their demographics; second, to gauge their perceptions regarding the credit risk and of the microfinance loans. The research employed a descriptive-correlational research design and was conducted in Brgy. Poblacion, Iligan City, involving a random sample of seventy-five business owners who completed an adapted and modified survey questionnaire. The findings revealed that a majority of the business owners were elderly individuals aged 51 years and older, primarily running cafeteria businesses. Many of these business owners had availed of microfinance loans for their enterprises, and a significant portion had recently experienced this process. It is noteworthy that the majority of micro-borrowers have limited incomes and a lack of substantial credit history. Over time, the microfinance sector has adopted risk mitigation strategies like group lending models and accepting specific collateral types.

Moreover, microfinance institutions have expanded their lending to microenterprises, assessing their creditworthiness based on cash flows. In conclusion, this study suggests that factors such as age, business type, prior loan utilization, and loan experience do not significantly influence individuals' perceptions of credit risk associated with microfinance loans. Thus, other unexplored factors may play a more prominent role in shaping how individuals perceive the credit risk in microloans.

Ada 6 Kabupaten/Kota yang menjadi fokus kajian karena memiliki kesamaan. Misalnya, Kabupaten Blitar, Kota Pasuruan, dan Kota Malang petahana dikalahkan. Sementara itu, Kota Batu dan Kota Kediri bercita rasa politik dinasti. Soal politik dinasti ditemukan juga di Kabupaten Bangkalan, Kabupaten Probolinggo, dan Kabupaten Banyuwangi. Selanjutnya, buku ini juga menampilkan variasi peta politik lokal di tiap Kabupaten/kota. Data empirik menunjukkan bahwa jalur parpol sangat dominan digunakan kandidat, ketimbang calon independen. Bahkan, dalam kasus di Kabupaten Kediri, kandidat memborong partai demi memenangkan Pilkada. Strategi ini dalam konteks demokrasi prosedural menimbulkan persoalan serius karena mempersempit partisipasi dan kontestasi dalam perebutan kekuasaan kepala daerah.
Pengelolaan Limbah Ternak
Authors: Junus Mochammad , Akhiroh Puji , Putritamara Jaisy Aghniarahim
Published: November 2023

Limbah adalah sisa proses produksi atau bahan yang tak bernilai, tak berharga, atau tidak laku dijual. Limbah ternak dibentuk dari pakan yang tersisa dari proses pencernaan. Pakan yang dikonsumsi ternak diproses oleh tubuh melalui saluran pencernaan dengan awal masuk melalui mulut ternak. Limbah ternak dibedakan menjadi limbah padat dan cair. Pembuangan limbah ternak umumnya dilakukan oleh peternak melalui beberapa cara antara lain dibuang di sekitar kandang, di dalam kandang, dialirkan ke sungai dan ditampung dalam bak penampung untuk selanjutnya dijadikan pupuk organik. Ancaman yang dapat muncul akibat dari adanya limbah ternak yang tidak dikelola dengan baik yaitu global warming akibat dari efek gas rumah kaca karena limbah ternak umumnya mengandung amonia (NH3), gas metan (CH4) dan dinitrogen oksida (N2O). Oleh karena itu, limbah ternak memerlukan manajemen penanganan agar keberadaannya tidak merusak lingkungan dan memiliki nilai manfaat yang lebih. Penjelasan manajemen limbah ternak dari buku ini dijelaskan dalam beberapa tahap yaitu 1. Perencanaan (plan), 2. Pelaksanaan (do), 3. Pengawasan (check) dan 4. Aksi (action). Perencanaan pada manajemen limbah ternak perlu memperhatikan hal-hal berikut: 1. Menyalurkan limbah ternak, 2. Menghitung limbah ternak, 3. Menampung limbah ternak, dan 4. Memanfaatkan hasil penampungan limbah ternak. Pengelolaan limbah ternak dapat dipercepat dengan adanya bantuan dari mikroorganisme seperti contohnya EM (Efektif Mikroorganisme). Pengelolaan limbah ternak dapat memanfaatkan EM dalam mengendalikan proses fermentasi dengan tujuan tertentu seperti mengubah limbah menjadi bahan pakan ternak, media jamur, media pakan cacing, media atau pupuk tanaman darat dan air yang memenuhi persyaratan. Limbah ternak juga dapat dimanfaatkan sebagai pupuk, pakan ternak, produksi gas bio dan pembentukan pertanian terpadu. Limbah ternak saat ini menjadi masalah dalam proses pemeliharaan ternak dan lingkungan sehingga perlu dikelola secara tuntas dan tidak meninggalkan bekas (zero waste). Penanganan untuk pengelolaan limbah ternak diarahkan pada proses aerob dan anaerob yang multiguna untuk mendapatkan produk yang bermanfaat bagi manusia dan lingkungan dengan tetap mengkaji dari segi ekonomisnya. Kajian ekonomi mengenai pengembangan biogas dari limbah ternak meliputi aspek teknis, aspek pasar, aspek institusional-organisasi-manajerial, dan aspek sosial dengan memperhatikan dampak ekonomi dari adanya pengembangan biogas tersebut. Buku ini mampu memberikan informasi secara detail mengenai limbah ternak secara umum sampai pada proses pengolahan, pemasaran, dan kajian ekonomisnya serta memiliki penjelasan yang mudah dipahami oleh khalayak umum.

Secara garis besar penelitian dapat dipilah menjadi penelitian normatif dan empiris. Penelitian empiris dapat dilakukan melalui pendekatan kualitatif, kuantitatif dan mix method. Pada penelitian kuantitatif, kajian yang dilakukan sering mengenai perilaku sistem, misal sistem sosial, ekonomi, dll. dimana umumnya disederhanakan dan didekati melalui model. Pemodelan tersebut memerlukan landasan ilmiah (teori dan konsep hasil penelitian) yang kuat. Konsep hasil penelitian dapat digali melalui telaah pustaka yang bersumber dari artikel jurnal. Pada era digital dan big data saat ini, publikasi ilmiah berakselerasi tinggi sehingga ketersediaannya banyak dan melimpah. Big data dicirikan dengan volume, variety, velocity, veracity, dan data value. Volume terkait ukurannya sangat besar, variety adalah sifat data yang heterogen (beragam) berupa data tekstual, data media sosial, data dari berbagai bidang. Velocity berkenaan dengan kecepatan data yang dihasilkan secara real-time, dan data Value berfokus pada wawasan tersembunyi (hidden insight) dari kumpulan data. Telaah pustaka, tinjauan pustaka, atau literature review dapat dilakukan secara tradisional atau juga disebut dengan narrative review (NR), yaitu dilakukan secara manual dan dikerjakan oleh peneliti sendiri. Pada era big data yang dicirikan dengan volume, variety, velocity, veracity, dan data value maka NR mengalami kendala. Oleh karena itu, mahasiswa, dosen, dan peneliti mau tidak mau harus bergeser ke konsep big data dalam melakukan telaah pustaka, yaitu melalui systematic leteratur review (SLR). SLR berkerja dengan kecepatan tinggi, dapat menjangkau publikasi ilmiah dengan volume besar yang memiliki variasi tinggi dan kekinian. Buku ini mengulas tentang aplikasi SLR, khususnya guna pemodelan sistem. Dengan menerapkan konsep big data, model yang dirancang atau diperoleh akan memiliki landasan ilmiah yang kokoh dan sekaligus memiliki novelty. Sehingga buku ini dapat digunakan sebagai rujukan untuk kegiatan penelitian dan juga dapat digunakan sebagai pegangan untuk perkuliahan metodologi penelitian, pada jenjang program S1, S2 dan S3, serta sebagai referensi para peneliti di berbagai bidang keilmuan. Penulisan buku ini digagas dan dimaksudkan untuk bisa membantu bagi yang mengalami kesulitan di dalam melakukan penelitian, khususnya tentang perancangan model yang memilki novelty. Ide atau gagasan sebaik dan sebrilian apapun jika tidak disampaikan kepada orang lain, tentunya akan kurang bermanfaat. Semoga ide dalam buku ini dapat diziarahi oleh banyak orang dan memberi manfaat bagi masyarakat secara luas. Bagi para sejawat dosen, buku ini dapat digunakan sebagai media sharing dan bahan bacaan untuk pengaya materi metodologi penelitian.
Upacara Unan-Unan Tengger: Membentang Kearifan Ekologis, Mewujud Keselarasan Kosmis
Authors: Sukmawan Sony , Febriani Rahmi
Published: November 2023

Sejumlah pembahasan mengenai Tengger dengan perspektif eko-kritik telah banyak dilakukan, tetapi pembahasan tersebut belum sampai pada telaah yang spesifik dan komprehensif terhadap helatan utuh suatu upacara adat di Tengger. Padahal, lingkungan selalu terlibat dalam pelaksanaan upacara. Oleh karena itu, perlu adanya pembahasan mendalam mengenai hal ini, khususnya upacara Unan-unan yang sarat dengan aspek ekologis. Adapun buku ini membahas eksistensi folklor Unan-unan Tengger sebagai representasi ideal dalam menggambarkan hubungan antara kearifan ekologis dan keselarasan kosmis masyarakat Tengger. Unan-unan merupakan sarana bagi masyarakat Tengger untuk bernegosiasi dengan kekuatan-kekuatan gaib yang dapat merusak keseimbangan alam dan kehidupan. Hal ini menunjukkan bahwa kesadaran ekologis telah begitu kuat terbentang dalam imajinasi masyarakat Tengger, baik secara fisik maupun psikis. Nilai-nilai ekologis tersebut diwujudkan dalam (i) ekspresi adat berupa penghormatan terhadap alam semesta melalui pelaksanaan upcara Unan-unan yang berkelanjutan dan konservatif; (ii) menjadikan alam sebagai orientasi dalam menentukan berbagai aktivitas religio-kultural dan sosial; (iii) terklasifikasinya sesaji Unan-unan yang secara khusus berfungsi sebagai penyelaras dunia fisik dan batin Wong Tengger; dan (iv) pemanfaatan Unan-unan sebagai poros pendidikan.

Materi buku Model Manajemen Sumber Daya Perairan Waduk Serbaguna (Studi Kasus Waduk Selorejo) ini bersumber dari penelitian kerja sama antara Tim Dosen Prodi Manajemen Sumber Daya Perairan Fakultas Perikanan dan Ilmu Kelautan Universitas Brawijaya dengan Perum Jasa Tirta I di Waduk Selorejo. Informasi yang tersedia dalam buku ini mengenai latar belakang permasalahan Waduk Selorejo dan informasi klasifikasi kualitas air, status mutu air, status mutu air, status trofik, daya tampung beban pencemaran, daya dukung, dan zonasi perairan waduk. Kegiatan ini juga melibatkan pemangku kepentingan untuk menyelesaikan masalah waduk secara kolaboratif. Model pengelolaan waduk serbaguna menerapkan teknologi ekoakuatik menggunakan biota air, dalam hal ini komunitas plankton, khususnya fitoplankton dan faktor lingkungannya untuk menganalisis status kesehatan perairan waduk. Berdasarkan hasil analisis diberikan solusi dengan teknologi ekoakuatik (menggunakan pendekatan rantai makanan untuk menyelesaikan masalah perairan). Pemilihan plankton dibandingkan dengan biota air lainnya karena berkaitan dengan karakter tipe perairan waduk yang bersifat menggenang. Selain itu juga diberikan rekomendasi penggunaan teknologi manajemen atau terapan manajemen untuk menyelesaikan masalah perairan waduk secara holistik. Buku ini hasil sinergi terapan dari 10 mata kuliah yaitu Planktonologi, Limnologi, Ekologi Perairan, Biomonitoring, Pencemaran Perairan, Pemetaan, Penginderaan Jarak Jauh, Produktivitas Perairan, Manajemen Sumber Daya Perairan dan Konservasi Sumber Daya Perairan. Tujuan penulisan buku ini adalah untuk diseminasi hasil penelitian di kalangan mahasiswa dan pemangku kepentingan Waduk Selorejo. Semoga informasi dalam buku ini memberikan manfaat khususnya untuk model pengelolaan sumber daya perairan waduk serbaguna di Indonesia.
