The Kukunor lake campaign of the Oirats 1636–1637: run-up
Authors: Kitinov B. U. , Lyulina A. G.
Published: December 2022

The main issues discussed in the article are as follows: 1. identification of the time and place where the envoys of the Tibetan Geluk leaders met with the Oirats; 2. establishing the exact place of gathering and advancing of the Oirat army towards Kukunor lake in the autumn of 1636. The authors suggest that the commander-in-chief of the army was Elet (Dzungarian) Batur-Khuntaiji, who later became the "deputy" of the Khoshut Gushi Khan. The arrival of Lama Tsagan Nomyn Khan to the Oirats from the nomad camps which belonged to the Eastern Mongolian ruler Altyn Khan in 1616 enabled their leaders to send their sons to the Tibetan Geluk school monasteries and consequently to establish close relations with their leaders. The following period of 20 years of the Oirat history (between 1616 and 1636) was filled with vivid and dramatic events. Among them were the war with Altyn Khan and civil strife, during which the Khoshuts, Derbets, and in general the Oirats were significantly splitted. At the same time, the influence of the Elet Khara Khula became more significant, which was reflected in the fact that his son Khotogochin, who succeeded him in 1634, received from the Dalai Lama the title "Batur-khuntaiji". Since the second half of 1634, the leading Oirat rulers and above all the Elets (who later on became Dzungars), were geographically close to their former homeland. At that time they met in the Tarbagatai region with Geluk envoys, who asked for help to fight against their enemies in Tibet. The early connections of the Elets with the lamas, as well as the special attention, that the Geluk lamas paid to Elets' leader, invite a suggestion that he was the addressee of that appeal. However, as a result, the Oirat army was led by Khoshut Gushi Khan. The army was gathered near Alakol lake and in the autumn of 1636, it moved towards the Kukunor lake through the Dzungarian Gate.
Collection of Manuscripts in Oirat in Ulan-Khol khurul of Kalmykia
Authors: Menyaev B. V.
Published: December 2022

This article presents a brief overview of the collection of manuscripts in the Oirat language stored in the fund of the Ulan-Khol Temple of the Republic of Kalmykia. The collection under consideration is relatively small (50 manuscripts), but it contains very interesting materials. The manuscripts of the Ulan-Khol Temple were a part of a significant collection of Buddhist writings in Tibetan, Old Mongolian and Oirat in the library of the Shars-Bagut (Northern) Temple, which was located from 1889 to 1939 in the area of Bora, Shars-Bagut aimak located in Erketenevsky ulus. The manuscripts were transferred to the Ulan-Khol Temple by relatives of the clergymen Bodgur Ochirov (1892-1955) and Tsagan Atkhaev (1900-1981). The collection seems to be extremely heterogeneous: it includes fiction literature works, orders, prophecies, ritual texts, prayers, astrological works, texts of divination, weather signs and traditional folk medicine texts. Some collections contain texts in Oirat with Tibetan inclusions as well as ones in Tibetan with Oirat interlinear. The fact proves Kalmyk monks were equally fluent in Tibetan and Oirat. The heterogeneity of the composition of the manuscript collection of the Ulan-Khol khurul indicates that the monks of the Shars-Bagut Temple in their main practice were not only clergymen, but also astrologers, soothsayers, healers. The presented texts are a valuable source for studying traditional religious beliefs, philosophy, ethics, old written Kalmyk literature, astrology and Kalmyk cult rituals.
“An outstanding lama of the West taught...” – M. Pallis and his treatise warning Tibet about the consequences of Kali Yuga
Authors: Korablin D. A.
Published: December 2022

The crisis of Tibetan statehood in the second half of the 1940s and the beginning of the 1950s accompanied by the relaxation of restrictions for foreigners to enter the country and by the next round of interest in Tibetan culture in general allowed many European explorers and travelers to reach Tibet and other inaccessible places of the Indo-Tibetan frontier. Their expeditions have resulted not only in the increase of the number of scientific publications on Tibet, which have defined the basic trends in modern Buddhist and Tibetan studies, but also in the increase of literary and artistic works, which have shaped “the image of Tibet” in the Western culture. A treatise prepared and written by the British researcher of Tibet and the Himalayas M. Pallis (1895–1989), which is the subject of this article, takes a special place in Tibetology, since it is a text not only about Tibet, but also for Tibet. The text was published in Tibetan as a detailed commentary on the political testament of Dalai Lama XIII (1876–1933), and its potential readers, first of all, were supposed to be Tibetans. At the same time, the text allows us to notice the intersection of the ideas of European philosophy of traditionalism and Indo-Buddhist ideas about Kali Yuga, and the appearance of the treatise can be regarded as a result of various transcultural communications between the Tibetan culture and representatives of Western philosophical thought in the mid-20th century.
Pulp Fiction: Indonesian detective from 1950–1960s’
Authors: Frolova M. V.
Published: December 2022

The article offers a detailed analysis and comparison of four works of popular Indonesian literature (two texts dd 1955 and two dd 1967) in order to trace the vectors of development of the detective genre in the Indonesian literature. The analysis precedes an excursion into the history of criminal genres in the literature of Indonesia. The study shows that, using the selected texts as an example, there is a certain difference between the detective-type literature before the political changes and the transition to the New Order (1965), and afterwards, also allows us to take another step towards the study of the detective genre in Indonesian literature.

Progress monitoring of construction work is crucial to identify the discrepancies between the as-built product and as-planned design and take necessary action based on the results. Construction work is time consuming and labour intensive. However, the use of new technologies, such as computer vision (CV), in construction progress monitoring (CPM) can minimise human errors. Thus, the aim of this study was to explore the current applications of CV in the construction industry in general and in the different stages of CPM. A qualitative approach based on the Delphi technique comprising two interview rounds was used to collect the required data. The study findings revealed that CPM has seven stages: initial planning, data acquisition, information retrieval, verification, progress estimation and comparison, results visualisation and schedule updating. During these stages, CV can be used in various CPM activities, such as earthmoving operations, crane operations, formwork and rebar tracking, worker activity tracking, safety assurance, landscape identification, work item monitoring and integrating with other technologies. Familiarisation of the workforce with CV and research on the applications of CV in construction can help the construction industry to move with technology and be on par with other industries. This study would enable construction personnel to explore the possibility of applying CV in CPM. Further research on identifying the synergy between CV and CPM can be based on the study findings.
As-built data acquisition for vision-based construction progress monitoring: A qualitative evaluation of factors
Authors:   Department of Civil Engineering, IIT Madras, India & UTS, Australia, Reja VK , Varghese K , Ha QP
Published: December 2022

The accuracy of computer vision-based progress monitoring of construction projects depends on the quality of data acquired. The data acquisition can be conducted through different vision-based sensors combined with several options for sensor mounting. Several factors affect this combination and considering these factors in selecting the acquisition technology and sensor mounting combination is critical for acquiring accurate vision-based data for the project. Currently, their definition and impact of these factors on the selection of these technologies are both subjective, and there are no formal studies to evaluate the impact. Hence, in this study, we first identify and define twelve key factors affecting data acquisition technology and eight factors affecting sensor mounting. Next, a questionnaire survey was designed, and responses from professionals were used to evaluate the Relative Importance Index (RII) for the individual factors for these technologies and methods. The obtained ratings were compared to the author's initial assessment, and the cause for a few variations obtained was justified. This study provides a clear assessment of these factors and forms a basis for selection based on the factors involved with the project requirements.

Published: December 2022

A major drawback in the present industrial system is that the industries are directly discharging industrial effluent to nearest waterbodies in a linear way. Even though, a few of industries have considered reusing treated and untreated wastewater in their industrial premises, it can be further extended towards ‘exchange’ among the multiple industries under the concept of Industrial Symbiosis (IS). Initiating IS-based treated wastewater exchange networks is a novel approach to Sri Lankan industries and there is a lack of a study on potentials and barriers of implementing the concept. Hence, this research aimed to investigate the potentials and barriers for exchanging treated wastewater among industries. In order to achieve the aim, 16 semi-structed interviews were conducted with industry experts in the field of Industrial Water Management (IWM) to collect the data. Code-based content analysis technique was used to analyse the data by applying QSR NVivo.12 software. Findings revealed geographical proximity of industries, willingness of industries to engage in water exchange and industry level water management initiatives as major potentials for initiating water exchange networks. Lack of expected water quality for industrial needs, outdated technologies used in water management and lack of expertise and awareness were identified as major barriers. Accordingly, strategies, such as introducing national policy enhancements, ensuring cultural adaptation, enhancing technology & infrastructure, and empowering research & development, were proposed to overcome the identified barriers to ensure a successful implementation of treated wastewater exchange networks targeting the socioeconomic development of the country.

Published: December 2022

Dams have become a very important infrastructure that provides enormous benefits to the economy of the country. Even though dams are very important and significant structures within a country, their breaks can cause severe damage to the country’s economy, society, and environment. Other than that, it can be impacted human life by causing deaths. As a come-up strategy, early warning systems can be used to reduce the severe impacts of dam breaks. Early warning systems (EWS) have been identified as a very important tool used to save lives and properties from disasters. Hence, this paper attempts to identify the functional characteristics of an EWS that can be used to reduce the impacts of dam breaks in Sri Lanka. An extensive literature survey was conducted to achieve the primary objective of this paper. Accordingly, the paper has identified the major purposes of dams, the causes for the dam breaks, and the impacts of dam breaks on the economy, society, and the environment. Then, the paper explores the functional characteristics of the EWS which is used for dam breaks. Finally, a conceptual framework has been developed with the key literature findings of the paper in order to minimise the social, economic, and environmental impacts created by dam breaks using early warning systems in Sri Lanka. As such, this paper will be a value addition to support the country’s economy, society, as well as environment.

Published: December 2022

Risk management often becomes a significant concern among the construction professionals especially due to the complex nature of the industry. Though it is a popular subject in project management discipline, it was observed that authentic application of the principles of risk management at times is arguable in practice. As a Project Manager who is a key role player in a project, it is vital to have a solid knowledge on risk management and its related arena. Evidence was found of limited risk management knowledge among construction professionals. Therefore, a study was conducted to find the status of risk management knowledge among the construction Project Managers in Sri Lanka. A mixed method approach was followed by a comprehensive literature review on elements of body of knowledge of risk management and later a questionnaire survey to contextualise the status of the knowledge gap of Project Managers in real. According to the findings of the study, it could be concluded that Sri Lankan Project Managers are not fully confident on their risk management knowledge. It was primarily likely to be due to the limited learning in the subject area when pursuing higher studies. The study also identifies the options to device appropriate strategies to improve risk management knowledge among the Construction Project Managers in Sri Lanka
Adaptability of blockchain-based E-Procurement system in Sri Lankan construction projects
Authors:   Department of Building Economics, University of Moratuwa, Sri Lanka, Nitharsan N , Francis M
Published: December 2022

E-procurement and Blockchain are relatively new technologies that have the potential to provide a variety of benefits due to their unique features such as transparency, decentralized approach, immutability, and consensus. The Sri Lankan construction industry is corrupted and that drives up construction costs, which are then passed on to the general public. Procurement plays a major role in construction projects as it is the basis of any transaction. E-Procurement is one of the recent technologies used by modern businesses to save time, money, and effort. Therefore, the current research aims to investigate the adaptability of e-procurement using Blockchain technology in the Sri Lankan construction industry. A mixed research approach was adopted including a questionnaire survey and semi-structured interview. A total of 55 questionnaires were distributed among experienced professionals, and 37 responses were received. The data collected from the questionnaire survey were analysed using Relative Important Index (RII) and Gap analysis. For the interview, total of 5 professionals who have experience in procurement and tender management were drawn through the snowball sampling technique to identify the strategies for the adoption of Blockchain based E-procurement. The survey found that there is a gap between the desirability and readiness for Blockchain adoption. In addition, the eight important drivers and barriers to the adoption have been identified. As a result, from an organizational and governmental perspective, measures must be designed and implemented to overcome barriers and enhance readiness levels, so closing the gap between desirability and readiness. Finally, based on the findings, strategies for improving the readiness of Blockchain-based EProcurement practices in the Sri Lankan construction industry were identified.
Value engineering for the selection of a suitable type of foundation in metro rail projects: A case study from India
Authors:   Department of Civil Engineering, National Institute of Technology Warangal, India, Vilventhan A
Published: December 2022

The design and construction of foundation systems for metro rail projects require effective planning and performing analysis over various alternatives in achieving a suitable cost-effective solution. Often the foundation system is selected based on the Soil Bearing Capacity (SBC) and other onsite constraints are left unconsidered. This results in costly design changes during the execution stages and incurs severe delays in the project. This demands the application of advanced managerial techniques to select costeffective solutions during the design stages of metro rail projects. Value Engineering is one such function-oriented approach used in analyzing the functions of a product or a process and selecting a suitable solution that achieves all the required functions at the lowest possible cost. The application of the value engineering concept in metro rail projects would enable identifying suitable solutions while considering different alternatives over several criteria. Hence, this paper applies value engineering technique for selecting the suitable foundation type for the construction of metro rail projects. A case study of an ongoing metro rail project was considered and three foundation alternative types and nine significant selection criteria were identified. The foundation alternatives were quantitatively analyzed using the weighted evaluation technique. The results indicate that for limited availability of Right of Way (ROW), the foundation with Controlled Low Strength Mortar (CLSM) is highly suitable. In scenarios of limited ROW with less SBC use of pile foundation is identified as a suitable cost-effective foundation type.

Published: December 2022

Housing is an essential element of social development. One consumer may purchase such a house once for his/her entire lifetime. Therefore, when making a housing purchasing decision, it is intensively explored more than it is considered in purchasing other consumable products. Property developer has the responsibility of understanding the consumer behaviour. The main research problem is the lack of attention towards the analysis of the current housing market of the Colombo Metro region from the consumer perspective. An extensive literature synthesis was carried out to gather information on the general attributes of the housing market and determinants of housing supply. Furthermore, investigation on the housing demand and consumer behaviour reference to Colombo Metro region were conducted through the literature synthesis. Subsequently, case studies and a survey have been adopted to proceed with the study following the mixed research approach. Semi-structured interviews for case studies and questionnaire survey were employed as the primary data collection. The primary data analysis was conducted through manual content analysis, Relative Important Index (RII) techniques and elementary statistical analysis. The findings revealed, how the prospective consumers are considering Person, Product, Place, Price related factors when purchasing a residential property. For an example this research discovered that quick access to Colombo is the highly considered fact by the consumers. It revealed that the consumer behaviour in Colombo Metro region is different from other contexts. Therefore, carrying out a study to analyse the current housing will be very important to maximize the consumer satisfaction in house purchasing.

OBJECTIVE

The safety and efficacy of embolization with Gamma Knife radiosurgery (GKRS) for high-grade brain arteriovenous malformations (bAVMs) are uncertain. The purpose of this study was to elucidate the long-term outcome of a tailored embolization strategy with GKRS and identify the independent factors associated with bAVM obliteration.

METHODS

Between January 2014 and January 2017, a consecutive cohort of 159 patients with high-grade bAVMs who underwent embolization with GKRS was enrolled in this prospective single-center cohort study. All patients received a tailored embolization strategy with GKRS. The primary outcome was defined as bAVM obliteration. Secondary outcomes were neurological function and complications.

RESULTS

After a mean follow-up of 40.4 months, 5 patients were lost to follow-up. One hundred eighteen of the remaining 154 patients had favorable neurological outcomes with complete bAVM obliteration. A decrease in bAVM nidus size was observed in 36 patients. Five patients developed intracranial hemorrhage during the latency period, and 2 patients died. The Kaplan-Meier analysis showed that the obliteration rate increased each year and reached the peak point at approximately 3 years. The multivariate Cox regression analysis of factors affecting bAVM obliteration revealed that postembolization bAVM volume < 10 cm3 (p = 0.02), supratentorial location (p < 0.01), staged embolization prior to GKRS (p < 0.01), and mean Spetzler-Martin (SM) grade (p < 0.01) were independent factors associated with a high obliteration rate.

CONCLUSIONS

These data suggested that high-grade bAVMs treated using a tailored embolization strategy with GKRS were associated with a favorable clinical outcome and obliteration rate. Postembolization bAVM volume < 10 cm3, supratentorial location, staged embolization prior to GKRS, and low mean SM grade were associated with a high obliteration rate.

Published: December 2022

Entomofagija (konzumiranje kukaca) rijetko se prakticira u zapadnim zemljama, ali ova praksa je i dalje raširena u ostatku svijeta. Najčešće se konzumiraju kornjaši (Coleoptera), gusjenice (Lepidoptera), pčele, ose i mravi (Hymenoptera) i skakavci i cvrčci (Orthoptera), ali se više od 1400 vrsta kukaca smatra jestivim. Kukci predstavljaju dobar izvor većine hranjivih tvari potrebnih za ljudsku ishranu, iako sastav varira u odnosu na vrstu i razvojni stadij kukca. Kukci spadaju u skupinu „mini-stoke“, te je njihov uzgoj jednostavan, brz i efikasniji u odnosu na uzgoj drugih vrsta životinja. Potencijal za dalji razvoj ove proizvodnje hrane je velik, a modeli uzgoja nekih vrsta su već razvijeni. Kukci se mogu konzumirati na više načina, bilo kao cijeli ili prerađeni ili kao posebno pripremljene delikatese i predstavljaju važan izvor hranjivih tvari u mnogim dijelovima svijeta. Pripadaju skupini „nove hrane“, a na nivou cijele Europske unije dopušten je uzgoj i konzumiranje samo ličinki Tenebrio molitor (veliki brašnar), iako neke zemlje dopuštaju i uzgoj drugih vrsta.

Authors: Perko Tina
Published: December 2022

Die Isolierung von Curcuminoiden aus Kurkuma (Curcuma longa L.) wurde durch verschiedene Extraktionsmethoden und Lösungsmittel durchgeführt. Die erhaltenen Extrakte wurden mittels HPLC auf den Gehalt an Curcumin, Demethoxycurcumin und Bisdemethoxycurcumin analysiert. Darüber hinaus wurde das Einfangen freier Radikale und die antibakterielle Aktivität der Extrakte ermittelt. Die Ergebnisse zeigen, dass der höchste Ertrag des Extrakts durch herkömmliche Extraktion unter Rühren in Ethanol erzielt wird, was zur höchsten Konzentration an Curcuminoiden führt. Alle erhaltenen Extrakte zeigen starke antimykotische Eigenschaften, aber eine geringe antibakterielle Aktivität.

Published: December 2022

More than 50% relevant artery stenosis is regarded as significant and may be responsible for an ischemic lesion in the corresponding brain area. However, a lesion with less than 50% stenosis with carotid plaque is classified as an embolic stroke of an undetermined source and might be underestimated as a potential source of stroke. A 53-year-old woman with motor weakness of the left limb showed multiple scattered small infarct lesions in the right middle cerebral artery territory with less than 50% stenosis of the right carotid artery on magnetic resonance angiography. No embolic source was detected from cardiac assessments. Carotid duplex sonography showed a mobile thrombus and an ulcerative plaque in the right carotid artery, and these were confirmed by digital subtraction angiography. Our case report suggests that carotid duplex sonography can be useful in patients who have ischemic stroke with an embolic pattern without significant arterial stenosis.
L’art du « revenez-y ». Variations sur la mémoire chez les Goncourt
Authors: Charlier Marie-Astrid
Published: December 2022

Cet article propose une traversée de l’œuvre romanesque des Goncourt sous l’angle des représentations et de l’écriture de la mémoire, notion cardinale de leur œuvre et de leur vie, comme en témoignent aussi bien le Journal que leur passion pour la collection. Paradoxalement, les personnages se souviennent relativement peu dans leurs romans. Cependant, bien que discrète, la mémoire se déploie à des moments stratégiques du récit. Il s’agit ici de mettre au jour un véritable art romanesque du « revenez-y », lequel se déplie en différentes variations comme autant d’explorations psychologiques, narratives et esthétiques de la mémoire.  L’article explore ainsi les représentations tantôt pathologiques tantôt réparatrices de la mémoire à travers la nostalgie et la mélancolie des personnages mais aussi les enjeux de l’articulation entre mémoire, rêve et oubli dans la création goncourtienne. Enfin, il s’agit de dégager le travail de corporalisation de la mémoire à l’œuvre chez les Goncourt, notamment par l’intermédiaire des personnages du monde du spectacle : acteurs et actrices, mimes et acrobates.
« Une chasse aux souvenirs » : le travail de la mémoire dans l’œuvre autobiographique de Michel Leiris

Published: December 2022

Cette étude s’intéresse à la façon dont le travail de la mémoire est mis en scène dans l’œuvre de Michel Leiris. Dès sa première œuvre autobiographique, L’Âge d’homme, Leiris adopte une technique de composition novatrice, qui s’accompagne d’un développement considérable de son discours autobiographique, à travers lequel il se montre au travail. Mais cette inflation discursive n’est pas sans interroger, tant elle souligne que la remémoration est fatalement déformatrice, dans la mesure où elle reconstitue le passé à partir de la perspective actuelle du narrateur. Pourtant, à partir de La Règle du jeu, Leiris semble embrasser l’idée d’une libre réinvention de la mémoire. C’est qu’entre-temps, dans un texte de genèse intitulé L’Homme sans honneur, il a jeté les bases d’une réflexion originale sur la remémoration et l’écriture, qui anticipe sur les analyses ultérieures de Philippe Lejeune.

Proyek pengembangan lahan skala besar di Gedebage oleh Summarecon Gedebage yang semakin meningkat dan rencana Sub Wilayah Kota (SWK) Gedebage sebagai Pusat Pelayanan Kota (PPK) akan berpengaruh pada dinamika harga lahan secara signifikan. Investasi dalam pengembangan lahan akan terus meningkat dan akan mempengaruhi harga pasar lahan. Namun demikian, perkembangan harga lahan di kawasan sekitarnya tersebut belum diketahui secara baik. Penelitian ini bertujuan untuk menjelaskan dinamika harga lahan di sekitar pengembangan lahan skala besar dengan menggunakan beberapa metode, yaitu gabungan kerangka sampel Nilai Jual Objek Pajak (NJOP) dan metode geographical area untuk menentukan lokasi harga lahan, metode purposive sampling untuk menentukan broker lahan sebagai responden kunci. Dinamika harga lahan ditunjukkan dengan pertumbuhan median harga lahan dan peta isovalue menggunakan software Surfer DEM. Penelitian ini menyimpulkan bahwa terdapat dinamika harga lahan di wilayah studi yang disebabkan oleh adanya pengembangan lahan skala besar Summarecon Gedebage Kota Bandung. Faktor-faktor eksternal dan internal serta peristiwa-peristiwa penting yang terjadi baik tingkat lokal, regional, dan nasional juga mempengaruhi harga lahan di wilayah tersebut. Pertumbuhan median harga lahan di sekitar pengembangan lahan skala besar Summarecon Gedebage Kota Bandung dan jalan utama meningkat lebih cepat daripada sekitarnya. Fenomena-fenomena ini juga mempengaruhi harga pasar lahan di wilayah studi.

Published: December 2022

Berbagai penelitian terkait pembuatan rancangan campuran beton dengan menggunakan limbah slag mengalami perkembangan yang pesat. Dalam perkembangannya, slag yang merupakan produk limbah dapat digunakan sebagai material pembentuk beton (baik sebagai agregat halus, agregat kasar, maupun semen).  Semen slag merupakan jenis semen portland yang memanfaatkan slag dari industri baja sebagai salah satu bahan bakunya. Dalam proses produksinya, semen slag menghasilkan emisi CO2 yang rendah sehingga sangat ramah lingkungan dan layak disebut sebagai jawaban untuk konstruksi yang berkelanjutan (sustainable). Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan semen slag terhadap sifat mekanik dan durabilitas beton dengan komposisi yang digunakan sebesar 100% semen slag. Material semen slag yang digunakan terdiri dari  tipe LH (low heat) dan general.  Pembuatan rancangan campuran beton mengacu pada SNI 03-2834-2002 (Tata cara pembuatan rencana campuran beton normal), pengujian sifat mekanik beton mengacu pada SNI 1974-2011 (Cara uji kuat tekan beton dengan benda uji silinder) dan SNI 4431-2011 (Cara uji kuat lentur beton normal dengan dua titik pembebanan).  Uji resistivity dan permeabilitas dilakukan untuk mengetahui durabilitas beton.  Dari hasil uji laboratorium diperoleh bahwa terdapat peningkatan kuat tekan, kuat lentur dan durabilitas beton pada umur di atas 56 hari.  Beton dengan penggunaan 100% semen slag tipe LH kuat tekannya lebih besar 15% dari beton konvensional.   Nilai resistivity beton dengan semen slag tipe LH adalah 59 KWcm dan beton konvensional sebesar 14 KWcm, artinya bahwa beton dengan semen slag tipe LH lebih tahan empat kali terhadap laju korosi dari beton konvensional.  Berdasarkan hasil uji permeabilitas,   beton dengan semen slag tipe LH dan general mempunyai nilai permeabilitas dengan kualitas baik dan nilai indeks 2, karena berada dalam rentang KT  (0,01 – 0,1) x 10-16 m2. Sedangkan beton konvensional nilai permeabilitasnya berada dalam kelas normal dengan indeks 3 karena berada dalam rentang KT (0,1 – 1,0) x 10-16 m2.
