Authors: Setiawan Kadek Nando 
Published: August 2024

Ketidakteraturan penambangan sumberdaya nikel di Indonesia menyebabkan banyak masalah lingkungan yang serius. Tumpukan batuan sisa pada waste dump penambangan nikel berpotensi sebagai sumber rembesan logam berat ke airtanah. Tujuan penelitian ini adalah mengidentifikasi potensi pelepasan kromium hexsavalen yang dapat diakibatkan dari adanya kegiatan penambangan terhadap kualitas airtanah dan air permukan sekitar daerah pertambangan nikel. XRF (X-Ray Flourescence) dilakukan untuk mengetahui kandungan unsur dan mineral pada batuan. Toxicity Characteristics Leaching Procedure (TCLP) dilakukan untuk memperkirakan konsentrasi Cr6+ pada waste dump. AAS (Atomic Adsorption Spectrophotometer) untuk mengetahui kandungan Cr6+ pada sampel air permukaan dan airtanah. Hasil pengujian XRF kandungan Cr2O3 menunjukkan waste dump mengandung 2,409% – 2,985% Cr2O3 dengan rata – rata 2,729%. Hasil tersebut kemudian gunakan dalam analisis potensi pelindian laboratorium dengan TCLP, hasil menunjukkan kelarutan Cr (VI) sangat rendah yaitu dari ketiga sampel sebesar < 0,006 mg/l. Bedasarkan hasil tersebut maka dilakukan pengujian kandungan Cr (VI) dengan AAS pada beberapa sampel air untuk mengetahui hasil dari pelepasan atau pelindian Cr (VI) secara alami. Hasil penelitian menunjukkan konsentrasi tertinggi Cr6+ sebesar 0.0462 mg/L pada sampel sediment ponddekat waste dump. Oleh karena itu dapat disimpulkan bahwa logam berat Cr(VI) pada tumpukan batuan sisa dari waste dump dapat tertransportasikan kedalam airtanah maupun ke air permukaan.

Kota Palangka Raya merupakan salah satu kota yang menarik minat banyak pelajar dari luar kota Palangka Raya maupun dari luar Kalimantan Tengah untuk berkuliah. Dengan banyaknya lahan kosong serta peluang kerja menjadi salah satu faktor banyaknya pelajar dari luar Kalimantan berkuliah di Palangka Raya. Namun dengan tingginya biaya hidup di Palangka Raya membuat sebagian besar mahasiswa yang berasal dari luar daerah merasa cukup terbebani untuk menyewa tempat tinggal. Sehingga, asrama mahasiswa menjadi salah satu alternatif yang dapat membantu mahasiswa untuk tinggal selama menempuh pendidikannya. Namun kebanyakan asrama yang ditemukan tidak memenuhi fungsi sebagai asrama mahasiswa. Asrama mahasiswa tidak hanya sebagai tempat untuk tinggal saja, namun juga harus menjadi tempat para mahasiswa untuk belajar, berinteraksi serta sebagai tempat pembinaan bagi mahasiswa tersebut. Untuk memenuhi fungsi. Arsitektur Modern memiliki prinsip form follow function yang lebih menekankan fungsional serta efisiensi. Sehingga dengan penerapan Arsitektur Modern dapat menciptakan bangunan yang fungsional dan mampu memenuhi semua kebutuhan aktivitas penghuninya.

Social workers play a critical role in providing support and guidance to military families during deployment. They offer counseling services to help family members cope with the emotional challenges of separation and uncertainty.
By creating a safe space for families to express their fears and concerns, social workers can facilitate the healing process and strengthen family bonds. In addition, social workers play an important role in bridging the communication gap between deployed personnel and their families by ensuring that important messages and updates are effectively communicated. In addition, social workers connect military families with resources and support networks to help them navigate the challenges of deployment. Whether it's access to mental health services, financial aid programs, or educational resources for children, social workers advocate for the well-being of military families. In addition to the support provided by social workers, there are various programs and activities specifically designed to meet the needs of military families. Family therapy sessions are conducted to eliminate communication disorders and improve family relationships. These activities create a safe environment for family members to express their thoughts and feelings, ultimately fostering better understanding and cohesion.
The Sociolinguistic Dynamics of Grotesque and Satire
Authors: Liu Zhongxi 
Published: August 2024

Abstract
The grotesque and satire are common methods of expressing the comic in European and African American literature. This study identifies the distinctive features of the grotesque and satire in European and African American literature. Günter Grass in The Tin Drum, The Wide Field, The Rat, The Dog Years and Under Local Narcosis uses the grotesque as a primary means of representing the political and historical state of Germany. In Sula, Toni Morrison takes the reader into the opposite space. She blatantly exposes racism and the problems of African Americans, denouncing inequality and lack of freedom. These results allow us to comprehend and critically engage with the ways that these kinds of communication confront social reality and challenge societal norms by looking at the sociolinguistic dynamics of the grotesque and satire in German and African American literature.
The Future of Andrew Marvell
Authors: Tink James 
Published: August 2024

Abstract
The modern reputation of Andrew Marvell has developed from studies of his status as a metaphysical poet of time and scale, to more historicist investigations of his political engagements and a nascent liberal subjectivity. There are remaining questions about the precise ideas of futurity in his lyric poetry. This article identifies three themes in particular: the figure of the child as part of a discourse of heredity, the figure of the landscape in a process of change, notably in ‘Upon Appleton House’, and the singularly charismatic figure of Oliver Cromwell, especially in ‘An Horatian Ode’. It concludes by considering other potential notions of futurity as suggested through ecocriticism.
Into the Gray Zone
Authors: Sickle Ula 
Published: August 2024

Abstract
“Into the Gray Zone” conducts a theoretical analysis of the complex inter-mediality of the choreographic exhibition. Examining the inherent tensions that arise as live dance-based practice enters visual arts institutions, this article examines audience attention, individual and collective spectatorship, artistic labor and value, technology, and the influence of social media. It argues that the inter-medial nature of the choreographic exhibition and its porosity to online platforms and mobile communication provides a more accurate reflection of the mediated environments we are currently surrounded by, and living within, than the black box theater. How can dance-based practice be implemented in this gray zone of highly individuated and distracted attention in ways that can make our contemporary condition visible? How can it potentially, if temporarily, remediate these environments?

BACKGROUND
The prognosis for cancer patients has been improved because of the development of molecularly targeted drugs. Treatment of intracranial tumors must be personalized while prioritizing the treatment of comorbid cancers.

OBSERVATIONS
A 38-year-old man presented with bloody sputum, bilateral multiple nodules, and a mass in the lower lobe of his right lung. Bronchoscopy revealed stage IV lung adenocarcinoma with an epidermal growth factor receptor (EGFR) mutation. Screening head magnetic resonance imaging revealed a 38-mm-diameter mass in the left petroclival area. Because the patient was neurologically intact, the treatment of lung adenocarcinoma was prioritized, and the third-generation EGFR–tyrosine kinase inhibitor osimertinib was used. Although nodules in the lung began to shrink, the intracranial lesion expanded and caused hydrocephalus, necessitating a ventriculoperitoneal shunt. The tumor also caused diplopia, dysarthria, and gait abnormalities. A left anterior transpetrosal approach was used to remove the tumor derived from the trochlear nerve. The pathological examination revealed schwannoma. Neurological symptoms improved following surgery. Osimertinib was continued during the perioperative period.

LESSONS
Osimertinib was effective for lung adenocarcinoma but not for trochlear nerve schwannoma, which required surgical intervention. It is necessary to tailor the treatment of benign brain tumors in patients with concurrent malignant cancers.

Published: August 2024

BACKGROUND
Spinal cord diffuse midline glioma (DMG) is a relatively rare disease with a poor prognosis and no effective treatment.

OBSERVATIONS
A 45-year-old man presented with rapidly progressive paraplegia in both lower extremities, along with bladder and bowel disturbance. Spinal magnetic resonance imaging (MRI) showed a heterogeneously contrast-enhanced mass at the T1–4 levels. A biopsy via T1–4 decompressive laminectomy with expansive duraplasty was performed. The histopathological diagnosis was DMG, H3K27-altered, World Health Organization grade 4. Radiation plus concomitant temozolomide was started; however, follow-up MRI showed tumor progression. Additional hypofractionated radiotherapy (HFRT; 24 Gy/5 fractions) was performed, with bevacizumab (BEV) plus low-dose ifosfamide-carboplatin-etoposide (ICE) as second-line treatment. One month later, MRI showed tumor regression with significant improvement in the peritumoral edema. The chemotherapy regimen was repeated every 4–6 weeks, and the patient remained stable. After 13 courses of chemotherapy, the size of the spinal DMG increased markedly, with dissemination to the temporal lobe. The patient died approximately 21 months after the initial diagnosis.

LESSONS
Spinal DMG is a malignant tumor with a poor prognosis. However, treatment with additional HFRT combined with BEV plus low-dose ICE may inhibit tumor progression to prolong the progression-free period and survival.

ANALYSIS OF WORLD ENGLISH FEATURES IN THE GOVERNMENT ENGLISH TEXTBOOK
Authors: Lasito Lasito 
Published: August 2024

Abstract: The teaching of English has become entangled between standard English and regional varieties of English in light of sociolinguistics of globalization. Supported by World Englishes (WE) paradigm, English varieties created for local audiences are thought to improve standard English. Yet, due to the lack of teaching resources (such as textbooks) that address WE perspectives, it may be challenging to show WE as both a paradigm and a reality that is constantly present in the development of teaching English in a regional context. The purpose of this study is to identify any instances of WE perspectives on pedagogy in a textbook that had received government endorsement and to highlight any suggestive characteristics that help to make these WE perspectives operational. Analysis was conducted multimodally to texts and images on the content of learning materials presented in the textbook. Analysis to content and presentation of the textbook indicates that using local language effectively helps local learners understand the differences between the two forms of English without undervaluing the less widely used variety as a foreign language. Findings of this study also suggest that when teachers comprehend the relationship between local culture and the English language taught to the students, this might lead to the deployment of a pedagogical tool that allows various perspectives for language teaching and learning.Keywords: World English, standard English, local varieties, textbook, content
Microstructure and Corrosion Study on Friction Surfaced Aluminum Alloy Coatings over Mild Steel
Authors: Sivalingam Vinodh , Thirumalaisamy Ramakrishnan 
Published: August 2024

In this study, the low-carbon steel (AISI 1018 mild steel) substrate is coated with the aluminum alloys AA6082-T6, Al-20Zn, and Al-2Si-15SiC to improve its corrosion resistance by the friction surfacing (FS) technique. To produce a high-quality coating, friction surfacing process variables including spin speed, speed of travel, and the rate of feed are crucial. This experiment examines twelve friction-surfaced plates with different parameter combinations. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) examinations were carried out in order to comprehend the microstructure and chemical composition of the coating deposits and the area in contact between the coated surface and the substrate. Microstructure investigation reveals that the intermetallic combination of Fe-Al at the coating interface region is an effect of the elemental diffusion of Fe to aluminum at the contact interface. Then a uniform and fine-grained coating deposit is observed as a result of the continuous recrystallization of the consumable rod under frictional stress and heat generation. According to the outcomes of the microhardness test, the coated surface is roughly 15–16% harder than the consumable rod. The coating bond strength was measured using a ram tensile test, and it ranged from 102 MPa to 135 MPa. Finally, evaluation of corrosion behavior through immersion testing and pitting corrosion testing reveals that the coatings made of Al-20Zn and Al-2Si-15SiC exhibit good corrosive resistance in an alkaline environment.

MODEL PENANGANAN RESIKO LONGSOR DI LERENG SUNGAI CILEBAKCAWI DESA MUARASARI KECAMATAN BOGOR SELATAN
Authors: Ismiralda Dinta Anindy , Hadi Singgih Irianto Trisilo , Widia Winda 
Published: August 2024

Model penanganan resiko longsor pada lereng sungai dapat diawali dengan menghitung faktor keamanan lereng. Analisis faktor keamanan lereng didapat dengan menganalisis beberapa parameter material lereng dengan menggunakan program geo-slope. Parameter yang dibutuhkan adalah jenis material penyusun lereng dari hasil pemetaan geologi dan akusisi data geolistrik, sifat fisik dan mekanika tanah dari uji laboratorium, dan geometri lereng. Berdasarkan analisis faktor keamanan lereng Sungai Cilebakcawi, kondisi lereng dalam keadaan labil dengan nilai faktor keamanannya 0,983. Angka keamanan lereng pada lokasi penelitian juga sangat dipenaruhi oleh kedalaman MAT. Dengan kondisi labil tersebut perlu dibangun perkuatan lereng diantaranya dengan penggunaan bronjong kawat yang dikombinasikan dengan terasering dan pile. Hasil dari kombinasi perkuatan ini dapat menaikan angka kemanan lereng menjadi diatas 3,328 walau dalam kondisi MAT dangkal yang menunjukan lereng dalam kondisi stabil atau mantap.Kata kunci :Penanganan Resiko Longsor, Faktor Keamanan Lereng, FK, Bronjong kawat, pile.ABSTRACTThe model for handling landslide risk on river slopes can be started by calculating the slope safety factor. Analysis of slope safety factoris obtained by analyzing several slope material parameters using the geo-slope program. The parameters required are the type of material that makes up the slope from the results of geological mapping and geoelectrical data acquisition, the physical and mechanical properties of the soil from laboratory tests, and the geometry of the slope. Based on an analysis of the safety factor for the slopes of the Cilebakcawi River, the condition of the slopes is in an unstable state with a safety factor value of 0.983. The slope safety score at the research location is also greatly influenced by the depth of the MAT. With these unstable conditions, it is necessary to strengthen the slopes, including using wire gabions combined with terracing and piles. The results of this strengthening combination can increase the slope safety figure to above 3.328 even in shallow MAT conditions, which indicates the slope is in a stable or stable condition.Keywords:Model for Handling landslide, Slope Safety Factor, FK, Wire Gabion, pile.
