The character that must be possessed by graduates, especially prospective educators, is complex. Moreover, graduates as prospective educators must not only have the graduate character as predetermined, but also transfer these characters to their students in the future. Therefore, a strategy is needed that makes it easier for students/learners as prospective educators to have the expected character. This study describes character strengthening through speaking learning with using Language Learning Strategies (LLS). This study uses the method of literature study. Character strengthening can be carried out in each LLS stage according to the selected SBB. In other words, strengthening character according to the goals and functions of education, 21st Century HR, Industrial Revolution 4.0, Social Revolution 5.0, and even Merdeka Learning-Independence Campus can be carried out in an integrated manner in speaking learning with using LLS. Keywords: character, speaking learning, Language Learning Strategies

Authors: Golian Joanna , Anyszka Zbigniew , Kwiatkowska Joanna
Published: April 2023

A trial assessing the suitability of multifunctional living mulch to maintain the soil and reduce weed infestation was carried out in an organic apple orchard in the years of 2019-2020. Perennial plants (Alchemilla vulgaris, Fragaria vesca, Mentha piperita) and annual crops (Tropaeolum majus and Cucurbita maxima) were grown in the in the rows of the apple trees. The weeds number and soil weeds coverage in tree rows were assessed. Regardless of the living mulch species utilized, the soil resulted to be mostly covered by perennial weed species such as: Equisetum arvense and Taraxacum officinale and annual species such as: Lamium purpureum, Stellaria media, Galinsoga parviflora, Capsella bursa-pastoris and Poa annua, which were the most common species also for the natural cover used as control. However, all living mulch species limited weed infestation and M. piperita, F. vesca  and T. majus most strongly limited weeds growth. It is concluded that living mulch species can be a feasible practice to manage the soil on the tree rows in organic orchards.

Published: April 2023

Apricot is an important stone fruit species with different cultivars cultivated worldwide. Therefore, breeding programs are necessary for developing new varieties with various fruit quality and sensory traits. The present study evaluated morphological and fruit-quality attributes of thirty-seven apricot genotypes selected from several Iranian and Italian open-pollinated cultivars together with Shahroudi cultivar (control) during two growing seasons (2019–2020) using the UPOV descriptor and GT-biplot analysis. The results showed great variability in fruit size among all apricot genotypes studied. Most genotypes showed medium-sized fruits while large and small fruits were observed in eight and four genotypes, respectively. The highest yield was recorded in G-464, G-432, G-588, Shahroudi and G-571. Genotypes G-432, G-464, G-571, G-573, and G-576 had higher fruit weight than Shahroudi. In addition, G-450 and G-553 had the highest TSS (18.2°Brix) and TSS/TA (25.4), respectively. The GT-biplot analysis revealed that fruit weight and dimensions along with pH and TSS could be indicators for selecting superior genotypes. According to the present study, G-464, G-571 and G-450 can be introduced as superior genotypes and it is expected that the inter-crossing of these three have the potential to produce cultivars with sweet fruit, high yield and large fruit size.
What Drives Shareholders' Reaction To CEO Turnovers, Dividend Changes, and Block Trades? A Theoretical Background
Authors: Preś-Perepeczo Agnieszka
Published: April 2023

This study presents a review of theoretical concepts described in the literature that explain how corporate events might be perceived by investors. The theoretical discussion in this paper is related to three corporate events: CEO turnovers, dividend payouts, and block trades. The objective of this analysis is to identify and systemise the theoretical background for the drivers of shareholders' responses to these three corporate decisions. In other words, I will provide answers to the following questions: why is the market reaction sometimes positive and other times negative, and why is it sometimes stronger and other times weaker? Based on the literature review, I will show that each of the analysed corporate events might be perceived by shareholders as either positive or negative signals concerning perspectives and future cash flows. Consequently, corporate events might drive share prices up or down. However, shareholder reaction to one type of the event, such as CEO turnovers, will not always be homogeneous – only positive or negative. The strength of this reaction may also vary. The main reasons for these variations are the effectiveness of corporate governance mechanisms, investors' perceptions of the event, the event's peculiarities, and the company's characteristics, as well as other relevant circumstances and factors.
State Masculine Logics, Neoliberalism, and Canadian Federalism
Authors: Valcke-Beckett Karina
Published: April 2023

Institutional feminist theorists are interested in understanding how political institutions impact the creation of social policy and gender equality within a country. In Canada, institutional feminist scholars have predominantly focused on Constitutional jurisprudence and Charter politics to understand Canada’s institutional response to gender inequality. However, this literature is limited in its analysis of federal structures as being based within masculine logics, upholding patriarchal systems. Using a historical institutionalist approach, this paper looks at three stages of Canadian federalism: the 1867 two-nation compact, the Keynesian-Ford welfare state, and neoliberal ‘open federalism’ model. It finds that the non-static institutionalized gender biases in Canadian federalism have continued to favour masculine logics and bias, and disadvantages the creation of feminist social policy by the Canadian and provincial governments.
Resistance to Nihilism: Benjamin, Baudrillard, and Duchamp
Authors: Milić Novica
Published: April 2023

If we reread carefully some main texts written long ago by Walter Benjamin and Jean Baudrillard, we may find a scene of problematization not only of contemporary art but also of the contemporary state of the world, where nihilism in its different shapes should be met with resistance, both political and artistic. It really has become the world of simulacra, as Baudrillard would say, or the art in the age of technical reproducibility, as Benjamin suggested. To add to this problematic, the ambiguous status of Marcel Duchamp’s Fountain, produced, or, rather re-produced during the First World War and revived in art criticism and art practice after the Second – an oeuvre which is deemed as “the most influential work of art in the 20th century” – we are faced with the enigma of questioning our own response as a start of resistance to the historical nihilism we live today. This text of ours does not seek to give all, nor even some answers to this enormous problematic, but rather to sketch a framework of the ways we could look at the questions we need to ask ourselves.

Interpretation of Newspaper Photography: A Case Study of NIN Magazine
Authors: Vujović Marija , Mitrović Matra
Published: April 2023

The power of visual communication is undeniable for media theorists. Newspaper photography is an important and often dominant content in the media. One of its characteristics is polysemy, the possibility of having different interpretations based on one’s knowledge and experience, but also social and historical context. A photo on the front page of NIN magazine published on November 27, 2019, showing a weapon – a rifle – aimed at Serbian President Aleksandar Vučić during his visit to a weapons fair caused severe public criticism, and was removed from the front page by decision of publisher Ringier Axel Springer. The research question is whether the editor’s choice of this specific front-page photo complies with the provisions of the Serbian Journalists’ Code of Ethics, and whether the decision to remove it was justified.

The Matter of the Image: For a Material Aesthetics between Ontology and Linguistics
Authors: Montebugnoli Anna
Published: April 2023

This essay aims at understanding the role of matter and outlining material aesthetics in the age of the digital image. To do so, it first analyses the traditional link between matter and form within the framework of classic ontology and aesthetics, according to which matter is the passive principle of reality subdued to the action of form and its logos. It then attempts to rethink this relationship through the activation of matter in its metaphysical, as well as aesthetical and linguistical dimensions. Such activation is outlined through the analysis of the concept of “concrete sense” and “concrete metaphysics” developed by Pavel Florensky in his inquiry into the Orthodox icon, and through that of “vital semantics” defined by Roland Barthes in his essay on 16th century Italian painter Arcimboldo. The argument is that these two concepts allow for a different relationship among art’s praxis, ontology, and linguistics, leading to the first formulation of a material aesthetics, while also rethinking the temporality of both traditional and digital image.

About Nature: Discourses on the Boundaries of East and West in Curtis Carter’s Concern over Contemporary Chinese Art
Authors: Wah Man Eva Kit
Published: April 2023

American aesthetician Curtis Carter demonstrates genuine concern for the subject of nature in contemporary Chinese art and its representations. He correctly points out that the Chinese tradition of featuring nature in the arts represents an imaginary paradise grounded in an idealized nature. Carter’s concern regarding China’s entry into a state of globalization is the impact of Westernizing globalization on the place of nature in Chinese art. Before discussing his concern, this article provides a review of the meaning of nature in traditional Chinese art and revisits ink painter Shitao’s notion of nature in his most representative painting notes, Hua-pu. Curtis also mentions the Chinese garden, stating that gardens in urban settings are supposed to maintain the presence of nature, and exemplifying them as symbolic presentations of nature. In addressing Carter’s concern, a review of the aesthetic experience of visiting a Chinese garden is provided for background. Carter also suggests examining the practices of contemporary Chinese experimental art versus the practices of traditional art to determine whether nature will retain a significant place in today’s Chinese art practices under the strong influences of globalization. This article examines the contemporary ink landscape scene and suggests that new Chinese art involves the invention of new paradigms in art creation, the resources of which are now available globally, and that representations of nature and reality are transforming.

From Edo to Post-metropolis: The Floating Space of Sakariba (盛り場)
Authors: Farnè Federico
Published: April 2023

This paper will highlight suggestions and problems associated with representing Tokyo as the archetypical Far-East Asian post-metropolis, starting with the fascination of sci-fi and cyberpunk imagery. The two ideas operate differently within both European and Japanese urban space. This will be emphasized by the work of Deleuze and Guattarì, through their conceptions of tree and rhizome. The research will not limit itself to demonstrating the rhizomatic and fluid nature of Tokyo's urban space, which makes it a fully-fledged post-metropolis. It will also identify some of the rhizome's main nodes or junctions, thus highlighting its conformation in terms of efficient strength.

Those Who Want to Play: Pursuing Animal Politics in Upbringing and Education
Authors: Bulatović Marija
Published: April 2023

Education is based on intergenerational divisions into the separate worlds of childhood, adulthood, and seniority which educational scientists further divide into even smaller stages. In this paper, in order to problematize the defined modalities of the existence of a child, an adult, and an elderly individual, I will prompt the rooted opinion that play is characteristic of childhood, while the game is typical of later stages. I intend to find in the human lifespan the moments when, after childhood, an adult abandons to play, and to propose the manners of overcoming the intergenerational differences in formal education as a field for surpassing the given in the entanglement of education and life. To surpass the given is extremely important at a time when education is instrumentalized. One of the ways the human can surpass the given is if they extract from play the principle which Massumi calls ludic expressionesqueness that is not immediately noticeable and that has the potential to reinvigorate both educational practices and life itself. Finally, I will examine theories of education and educational practices to see if they have strengths they can rely on in inspiring ethico-aesthetic practices of becoming with the world.

Between Control and More-than-Human Events: The Listening Experience in the Light of Speculative Pragmatism
Authors: Souza Lima Henrique , Branco Germano Gustavo , Campesato Lílian , Nogueira Esteves Lucia , Mapurunga Marina , Bonafé Valéria , Reis Vicente
Published: April 2023

This paper presents an investigation into the relationship between listening and power in the context of information warfare through the theoretical framework of speculative pragmatism. The main objective is to investigate the possibility of thinking of the listening activity as a particular act of thought through the concepts of lived abstraction and subjectless individuation. For doing this, the first part of the article describes the relationship of reciprocal presupposition between current online information warfare and the production of a subjectivity tied to a narcissistic regime of subjection. The second part of this article describes the concept of lived abstraction, such as elaborated by philosopher Brian Massumi. The third part of this article consists of investigating the epistemological core of speculative pragmatism through Deleuze and Guattari’s concept of subjectless individuation, particularly the individuation of an event. In the last part, we speculate a possible understanding of listening as an act of thought that is potentially articulated outside the noological register of narcissism through the appreciation of a mode of artistic operation that work in a way of designing listening experiences.

From Polyphasic Latency to Polyrhythmic Concretion: Rhythm and Relation in Simondon and Whitehead
Authors: Portella Castro Vinícius
Published: April 2023

Is it possible to conceive of a conciliation between the relational ontologies of Simondon and Whitehead? The similarities between their work are evident, but so are the disparities. Simondon is perhaps the most rigorous physicalist of the 20th century; Whitehead offered us a strange energetic or sentimental idealism, thoroughly concrete in its actualization, but involving a God and a host of eternal objects. With the aid of the work of Brian Massumi, Luciana Parisi and Steve Goodman, I will try to argue that Simondon and Whitehead both offer rhythmic ontologies, although not quite explicitly. Whitehead generalizes subjectivity throughout all scales, Simondon generalizes the notion of individuation for all scales. The two strategies are radically distinct, but I believe both gestures could be understood as a sort of radically-pluralist panchronism. Being is resonance and feeling for Whitehead, a cosmic actualization of the divine appetition of God, whereas for Simondon being is the amplification of internal resonance. For both philosophers, the rhythms that precede us entrain us throughout all scales. Finally, in this context, a brief understanding of African polyrhythms will be presented as a possible prototype for the collective emergence of complexity from a plurality of durations.

Processual Creativity and Partial Incorporations
Authors: Gil Diego
Published: April 2023

Brian Massumi and Félix Guattari conceptualize the creative processual force of life that shapes the passages from the potential to the actual dimensions of experience. Throughout these passages, bodies, environments and their relational modes of felt perception crystallize into form. What the conceptual vocabulary of Massumi and Guattari offers is a tool box to register the processual creative forces that are predetermined towards a coming into shape of a body-environment (subjectivity), as well as to take into account the forces deflecting from capture. The relevancy of their concepts is in that they index the more-than-human operations of the forces that shape the production of subjectivity: their concepts express the forces that by being potential and more-than concrete are beyond registering of individual human consciousness. Considering that subjectivity is produced through the potential ingression of partial incorporations – brewing of body-time-spaces – this paper is a proposition to think-feel the entanglements of process philosophy and somatic practices. Moreover, having in mind that processual creativity is a force distributed beyond the human, it needs to be as well thought as an autonomous doing ‘of’ the world. Therefore, the concepts offered by Massumi and Guattari overspill the disciplinary containment of the art disciplines and become an ethico-aesthetic paradigm ‘of’ the world, one in which the resistance to the capture of the production of subjectivity goes hand in hand with the invention of ways to think-feel how bodies and environments become.

Authors: Yaldi Gusri , M. Nur Imelda , Apwiddhal Apwiddhal , Momon Momon
Published: April 2023

Dengan semakin tingginya laju pertumbuhan kendaraan bermotor seperti mobil penumpang dan sepeda motor, berakibat kepada semakin meningkatnya dampak negatif transportasi berupa peningkatan angka kecelakaan lalulintas, kemacetan di jalan raya dan krisis energi. WHO melaporkan bahwa kematian akibat kecelakaan di jalan raya merupakan penyebab kematian ke-8 tertinggi di dunia. Karena itu perlu segera di antisipasi, dan diantaranya adalah dengan menerapkan skema parkir berbayar untuk pengguna mobil penumpang dan sepeda motor sehingga penggunaan kendaraan pribadi dapat di kontrol dan dialihkan keangkutan umum yang sustainable dan ramah lingkungan. Penelitian ini bertujuan untuk menganalisis perilaku pengguna mobil penumpang dan sepeda motor di kota Padang terhadap skema parkir berbayar virtual yang akan diterapkan berdasarkan pada data yang dikumpulkan menggunakan survei Revealed Preference dan Stated Preference. Hasil analisis mengindikasikan bahwa pengguna mobil penumpang memiliki tingkat kesukaan yang setara antara parkir di badan jalan dan di luar badan jalan dengan durasi parkir rata-rata 1.43 jam, jarak lokasi fasilitas parkir yang diinginkan maksimal 179m dari pusat kegiatan dan biaya parkir rata-rata adalah Rp.3000. Untuk pengguna sepeda motor, lokasi parkir yang disukai adalah di luar badan jalan dengan jarak 25.9m dari pusat kegiatan, durasi parkir rata-rata lebih dari 2 jam dan biaya parkir rata-rata Rp.1480. Berdasarkan respon terhadap 3 skema parkir berbayar virtual yang ditawarkan, maka direkomendasikan untuk pengguna mobil penumpang berupa skema parkir berbayar dengan tarif progresif minimal Rp.5000 untuk satu jam pertama, jarak minimal lokasi parkir ke pusat kegiatan adalah lebih dari 179m dan ruang parkir diprioritaskan untuk durasi parkir singkat yaitu maksimal 60 menit. Untuk pengguna sepeda motor, skema parkir yang direkomendasikan adalah skema parkir berbayar di badan jalan dengan tarif progresif minimal Rp.5000 untuk satu jam pertama, jarak minimal lokasi parkir ke pusat kegiatan adalah lebih dari 25.9m dan ruang parkir diprioritaskan untuk durasi parkir singkat yaitu maksimal 60 menit. Namun, skema parkir ini harus di dukung oleh penegakan hukum yang serius, dukungan dari masyarakat dan tersedianya angkutan umum yang reliable dengan biaya yang terjangkau. Karena itu, penelitian berikutnya diarahkan kepada analisis perilaku pengguna kendaraan pribadi terhadap layanan angkutan umum dan fasilitas parkir yang terintegrasi.
Identifikasi Faktor Penyebab Penurunan Badan Jalan (Settlement) di Km. 128 Ruas Jalan Pekanbaru – Taluk Kuantan
Authors: Taufik Muhammad , Muhardi Muhardi , Yusa Muhamad
Published: April 2023

Ruas jalan Pekanbaru Taluk Kuantan sebagian besar melewati daerah perbukitan dengan kemiringan lereng sekitar 30o – 70o. Sepanjang daerah perbukitan ini merupakan daerah rawan longsor namun sejauh ini longsor yang terjadi masih bisa segera diatasi karena volumenya tidak besar. Hanya saja ada satu titik lokasi yang selalu bermasalah yaitu di Km. 128.  Pada lokasi ini selalu terjadi penurunan badan jalan dan miring ke arah sungai meskipun telah berulangkali diperbaiki. Usaha penanggulangan terakhir yang dilakukan oleh Kementrian Pekerjaan Umum dan Perumahan Rakyat, Direktora Jenderal Bina Marga Satuan Kerja Pelaksanaan Jalan Nasional Wilayah I Provinsi Riau adalah membangun lantai bertiang sepanjang 85 m dan dinding penahan tanah dengan fondasi tiang pancang sepanjang 120 m pada sisi arah sungai. Pada saat pelaksanaan, curah hujan cukup tinggi sehingga terjadi longsor yang mengakibatkan tiang-tiang pancang yang telah terpasang banyak yang bergeser sehingga perlu dilakukan penambahan titik pemancangan. Untuk mengetahui penyebab terjadinya penurunan badan jalan pada Km. 128 ini perlu diketahui struktur lapisan tanah bawah permukaan. Penelitian dilakukan dengan metode geolistrik resistivitas konfigurasi Wenner – Schlumberger. Metode ini dapat memetakan struktur lapisan tanah bawah permukaan secara horizontal dan vertikal dengan baik. Hasil interpretasi geolistrik menunjukkan pada kedalaman 4,5 m terdapat lapisan lempung lunak dengan kadar air tinggi setebal + 10,5 m. Lapisan ini sangat labil apabila di atasnya bertambah bebannya. Lapisan ini diduga menjadi penyebab terjadinya penurunan badan jalan. Lapisan ini mempunyai permeabilitas yang sangat rendah sehingga air terakumulasi di dalamnya dan dapat mendorong lapisan ini ke bawah. Lapisan ini juga diduga penyebab bergesernya tiang pancang yang telah dipancang. Di bawah lapisan tanah lempung lunak ini adalah tanah lempung kelanauan dan kepasiran dengan warna abu-abu dan sangat padat.
Studi Awal Pengaruh Perubahan Iklim Terhadap Perkerasan Kaku Di Atas Tanah Lempung Ekspansif
Authors: Haryanto Iman , Utomo Heru Budi
Published: April 2023

Perubahan iklim berpotensi merusak infrastruktur termasuk struktur perkerasan kaku. Perkerasan yang dibangun pada tanah dasar tanah eskpansif rentan terhadap kerusakan, termasuk pumping. Penelitian ini bertujuan menganalisis potensi dampak perubahan iklim terhadap struktur perkerasan kaku. Data suhu udara dan curah hujan tahunan rerata di Provinsi Daerah Istimewa Yogyakarta adalah 26,71C dan 200,13 mm. Proyeksi perubahan iklim Bank Dunia menyebutkan bahwa pada periode 2080-an suhu udara meningkat 0,3C per dekade dan curah hujan tahunan rerata menurun 15%. Metode yang digunakan adalah Thornthwaite Moisture Index (TMI) (sebagai indikator penciri iklim) dan metode empiris untuk menghitung jumlah kerusakan level 3 (parah) akibat pumping. Lima tipe perkerasan kaku yang terdapat dalam Manual Desain Perkerasan (MDP) 2017 dipelajari sebagai obyek studi. Beberapa hasil studi adalah sebagai berikut. Perubahan TMI pada tahun 1976, 2016, 2019, dan 2080-an adalah 36,8; 48,07; 6,71; dan 57,54. Pumping index sebesar = 134 in3 per in length dapat menghasilkan variasi void depths > 5 cm, sehingga perkerasan kaku dapat mengalami kehilangan dukungan (loss of support). Perubahan iklim meningkatkan pumping perkerasan kaku tanpa tulangan antara 1832%. Lima tipe perkerasan kaku yang terdapat MDP 2017 memiliki pumping index kurang dari 134 in3 per in length, sehingga perubahan iklim diperkirakan tidak mengakibatkan tipikal perkerasan kaku standar di Indonesia mengalami kehilangan dukungan (loss of support). Perkerasan kaku tanpa tulangan terindikasi lebih mudah mengalami pumping erosion akibat perubahan iklim daripada perkerasan kaku dengan tulangan

Konstruksi baja merupakan suatu konstruksi dalam pembangunan struktur yang sering digunakan pada saat ini baik dalam pembangunan gedung maupun jembatan. Hal ini dikarenakan material baja memiliki banyak kelebihan jika dibandingkan dengan bahan konstruksi lainnya. Seperti sifat baja yang memiliki kuat tarik yang tinggi dan berat sendiri yang lebih ringan walaupun baja memiliki berat jenis yang tinggi yaitu 7850 kg/m3. Seiring berjalannya waktu mulai ditemukan profil penampang castellated beam yang menjadi salah satu inovasi dalam penggunaan konstruksi baja. Penggunaan castellated beam lebih praktis dan ekonomis. Pada penelitian ini membahas tentang teknologi modifikasi balok profil IWF menjadi balok profil castellated dengan variasi bentang dan jarak antar lubang segidelapan pada bagian badan profil. Profil IWF standar yang digunakan yaitu IWF 150.75.5.7 yang diubah menjadi IWF 300.75.5.7 castellated beam. Properties material penampang yang digunakan yaitu modulus elastisitas (E) 200.000 MPa; poisson ratio (v) 0,3 ; tegangan leleh (fy) 300 MPa dan tegangan ultimit (fu) 450 MPa. Untuk melihat studi perilaku dari masing- masing bentang dan jarak antar lubang segidelapan dilakukan pembebanan secara static monotonic di tengah bentang sampai tercapai kondisi batas penampang dengan menggunakan software MSC Patran dan MSC Nastran. Hasil dari penelitian menunjukkan perubahan profil standar menjadi balok kastela menghasilkan beban ulitimit yang lebih besar. Variasi jarak antar lubang mempengaruhi jumlah lubang yang didapatkan dalam satu bentang yang sama. Penampang yang memiliki nilai beban ultimit dan kekakuan terbesar adalah IWF 300.75.5.7 CB dengan variasi jarak antar lubang 78 mm. Dan Penampang yang memiliki daktilitas terbesar adalah IWF 300.75.5.7 CB dengan variasi jarak antar lubang 39 mm. Penambahan bentang menghasilkan nilai kekakuan semakin kecil dan daktilitas semakin besar.

Bertambah besarnya tanggung jawab pemerintah daerah menuntut semakin banyak jumlah anggaran yang harus dikeluarkan dalam pembangunan. Hal ini merupakan tantangan dalam melaksanakan pembangunan yang berkelanjutan dan berkeadilan. Salah satu tunggang jawab tersebut adalah melakukan penanganan terhadap kerusakan bangunan utama irigasi yang masing masing memiliki manfaat, tingkat kerusakan, dan keterbatasan yang berbeda beda, sehingga penentuan prioritas rehabilitasi sulit untuk dilakukan. Studi ini bertujuan untuk menentukan prioritas penanganan bendung berdasarkan analisis tiga kinerja yang meliputi kondisi prasarana, ketersediaan air, dan luas area irigasi. Penilaian ini dilakukan pada lima bendung yang berurutan pada aliran sungai utama DAS Mayang. Proses pengambilan data dilakukan dengan penyebaran kuisioner kepada 9 orang dari Dinas PU Pengairan Jember dan 1 orang dari UPT Pengairan Mayang. Sedangkan data ketersediaan air dan luas area irigasi didapatkan dari Dinas PU Pengairan Jember. Penentuan bobot kinerja bendung dilakukan menggunakan metode AHP (Analytical Hierarchy Process). Penilaian tingkat kerusakan bendung dilakukan dengan pengamatan langsung dilapangan yang mengacu pada Permen PU No.12/PRT/M/2015. Hasil pembobotan kinerja bendung menunjukan bahwa kondisi prasarana 49%, ketersediaan air 42%, dan luas area Irigasi 9%. Bendung Tegal Waru merupakan prioritas utama dalam penanganan kerusakan.

Bata ringan merupakan salah satu inovasi di bidang material bangunan dengan menggunakan bahan kimia foaming agent, sehingga bobot bata menjadi lebih ringan. Bobot yang ringan merupakan salah satu keunggulan yang dimiliki bata ringan, hal ini berpengaruh signifikan saat bata ringan digunakan pada bangunan gedung bertingkat karena dapat mengurangi berat sendiri bangunan. Kuat tekan merupakan parameter yang digunakan untuk mengetahui kualitas bata ringan. Untuk menentukan kualitas bata ringan perlu dilakukan pengujian eksperimental mortar bata ringan yang memerlukan biaya dan waktu pengujian. Penelitian ini bertujuan untuk mengembangkan model simulasi numerik berbasis  Jaringan Saraf Tiruan (JST) untuk memprediksi nilai kuat tekan bata ringan. Model JST menggunakan nilai densitas mortar bata ringan sebagai data input. Data training dan testing dari hasil pengujian benda uji mortar bata ringan berbentuk kubus dengan panjang sisi 10 cm sebanyak 120 benda uji terdiri dari 105 benda uji digunakan untuk data training dan 15 benda uji digunakan sebagai data testing untuk memprediksi kuat tekan  mortar. Hasil pelatihan JST yang paling optimal menghasilkan nilai regresi training dan testing sebesar 0.93891 dan 0.95667. Berdasarkan hasil penelitian dapat disimpulkan metode JST dapat memprediksi nilai kuat tekan mortar bata ringan dengan nilai error yang hampir mendekati nilai 0 dan keakuratan lebih dari 90%. Dengan demikian dapat disimpulkan bahwa, metode JST dapat digunakan dalam memprediksi kuat tekan bata ringan.

Desa Seraya adalah salah satu desa di Kecamatan Karangsem yang dulunya sempat menggunakan sistem pemanenan air hujan (PAH) atau Rainwater Harvesting, namun sekarang mulai ditinggalkan dan beralih menggunakan PDAM. Kebutuhan air untuk keperluan sehari-hari di Desa Seraya sangat tinggi karena air tidak hanya digunakan untuk keperluan minum, mencuci baju dan aktivitas lain di desa, tetapi juga untuk memenuhi kebutuhan air untuk berternak. Jenis ternak yang dipelihara sangat beragam mulai dari sapi, kambing, babi dan unggas. Kebutuhan air yang banyak ini cenderung membuat tagihan pembayaran air PDAM sangat tinggi tiap bulannya, sehingga beberapa masyarakat sudah mulai mengeluhkan keadaan. Sistem pemanenan air hujan ini diharapkan bisa menjadi alternatif untuk memenuhi kebutuhan air di Desa Seraya atau mengurangi penggunaan air dari PDAM. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif dan penetapan sampel menggunakan teknik sampel acak sederhana (simple random sampling). Adapun data pendukung yang digunakan dalam penelitian ini yaitu: curah hujan, luas atap rumah, luas bak penampungan dan banyaknya kebutuhan air di Desa Seraya. Berdasarkan hasil analisis didapatkan potensi hasil panen keseluruhan air hujan dapat memenuhi 94,03% dari total kebutuhan air di Desa Seraya. Apabila menggunakan bak penampung yang sudah ada saat ini, hasil panen air hujan dapat memenuhi 14,51% dari total kebutuhan air di Desa Seraya, karena bak air yang ada saat ini hanya mampu menampung 15,44% dari total potensi air hujan yang dapat dipanen.

Perkembangan teknologi menghasilkan suatu sistem untuk mengelola informasi menjadi permodelan bangunan yaitu Building Information Modeling (BIM). Berbagai negara di dunia telah mengadopsi BIM dengan standar yang berbeda. Oleh karena itu tahun 2017, pemerintah mengeluarkan roadmap mengenai BIM berisi rencana penerapan untuk 5 tahun kedepan. Namun, hingga saat ini rencana tersebut belum dijalankan sepenuhnya.  Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat Nomor 22 Tahun 2018 telah mengamanatkan kebijakan implementasi BIM pada pembangunan gedung negara tidak sederhana, dengan ini secara tidak langsung telah mewajibkan kontraktor untuk segera mengadopsi BIM. Penelitian ini bertujuan untuk mengidentifikasi faktor pendukung dan penghambat adopsi BIM oleh kontraktor di Provinsi Aceh. Pengumpulan data dilakukan dengan penyebaran kuesioner terbuka dan skala likert kepada 67 perusahaan kontraktor. Selanjutnya data dianalisis dengan metode Relative Importance Index (RII) untuk mendapatkan faktor yang paling berpengaruh. Faktor pendukung terbesar dalam adopsi BIM adalah BIM dapat mempermudah proses perencanaan dan faktor yang menjadi penghambat adalah kurangnya kemampuan dan keterampilan sumber daya manusia. Hasil penelitian ini memberikan gambaran bagaimana proses adopsi dan penerapan BIM oleh kontraktor dalam pelaksanaan pembangunan di Provinsi Aceh. Dengan demikian dapat diperoleh gambaran sejauh mana kontraktor telah mengetahui, memahami dan menerapkan BIM dalam pelaksanaan pekerjaan di lapangan.
