Abstract
Background: Dental caries is a disease that is produced by the dissolution of local chemical surfacesof the teeth caused by product of microbial fermentation from dietary carbohydrates in the biofilmthat attached to the teeth. Streptococcus mutans as the primary microbial pathogen in the aetiology ofcaries. They have a characteristic ability to produce voluminous amounts of sticky, extracellularpolysaccharides in the presence of dietary carbohydrates, thus, help tenacious binding of theorganism to enamel. Caries can be prevented by regular tooth brushing and flossing as mechanicalplaque removal for cleaning the tooth. However, for many individuals, it difficult to eliminateStreptococcus mutans from the surfaces of the tooth by mechanical means alone over prolongedperiods. Consequently, for effective caries control, these methods should be combined with theantimicrobial agent such as mouthwash whould have a direct inhibitory effect on the microorganismthat can be bactericidal or bacteriostatic. However, they have several undesirable side effectsreported from clinical studies, including tooth staining, increased supragingival calculus formation,reversible desquamation of the oral tissue, burning sensation, bitter taste and altered tastesensations.The use of medicinal plants is highly considered, because of side effects of chemicalsubstances. Recently, Stevia rebaudiana Bertoni leaves extracts as herbal mouthwashes are beingtried and have been scientifically proven from several studies to be safe and effective to protectionagainst dental caries because of its inhibitory effect or antimicrobial property against Streptococcusmutans. Purposes: The main aim of this literature review article is to explain the potenciallyantimicrobial herbal mouthwashes from Stevia rebaudiana Bertoni leaves extracts towardscariogenic bacterial Streptococcus mutans. Conclusions: Stevia rebaudiana Bertoni leaves extractsas herbal mouthwashes can be strongly recommended as a caries preventing agent.

Abstract
Geothermal energy utilizes steam from earth subsurface to drive turbines, which then produce electrical energy. The remaining brine from the process will return to the reservoir through injection wells. The brine basically can be utilized before injection, since it has high temperature, for other direct use. This paper aims to analyze the brine as a heat exchanger fluid, and calculate the energy requirements for meeting room heaters, and then determine the design of Heat Exchanger (HE). The meeting room has a 20-cm thick wooden wall, with dimensions of 20103 m3. The room temperature will be set to be 21-27 C. The geothermal source is at 300 m from meeting room and its elevation is 20 m below. The brine temperature that will be utilized is 100 C, and it has 20 gpm and outdoor temperature is 14 C. The result of the design is the fluid flow from the heat source to the output that warms the room. The flow is divided into 4 stages: at the pump, heat exchanger, air transmission and the room. The estimated cost of the heat exchanger is then calculated based on the design.

Abstract
Soil is the basic of a structure or construction, such as building construction also highway construction, and it-ll become a problem if the soil had a bad properties inside. Bad properties of soil can have a bad impact for any constructions. You can experience damage to the structure, something that is very undesirable in construction. Bad properties we mean here are those soil that have low shear strength, relatively large shrinkage growth, high plasticity limit. The type of soil found in the Atma Jaya University Makassar area is clay soil, so the author tries to investigate the effect of expansive soil stability based on the addition of styrofoam material in different levels of addition (5%, 10%, 15%, 20%, 25%), with the research title: “ENGINEERING PROPERTIES OF CLAYEY SOIL STABILIZED WITH STYROFOAM (C_{8}H_{8})” Based on the topic we chose, it means to require the stabilization as what the soil needs it absolutely takes so much efforts to improve the soil properties before doing a construction by enhancing the strength of it. There are two ways for enhancing soil properties, such as mechanical process and chemical process. One of the chemical process that will be applied here is with the additions of “Styrofoam” in the soil sample. The methodology we use on the laboratory testing are: moisture content testing, density testing, Atterberg limits testing, filtration analysis testing, and the compaction testing. The result is the significant change on the clay soil compaction test chart at the adding of 15% Styrofoam on the soil sample taken from Atma Jaya University Makassar-s ward. The significant changes we mean are the decreasing value of optimum water content from 23% to 16% and also value of maximum dry weight (γdry max) on the clay soil sample from 3.676% to 1.554%.

Abstract
The application of IoT in Vehicular Ad-Hoc Networks (VANET) allows the realization of intelligent transportation systems to ensure the comfort and safety of road users. But as an implication, attacks that can interfere with this aim certainly need to be a significant concern. It is because the stakes are not only network security but also the safety of the driver and its passengers. One of the attacks which had a substantial impact on VANET was the Sybil attack. Sybil attackers illegally change into several different identities to carry out malicious activities such as disrupting routing, causing traffic jams, bottlenecks, and even accidents. Various security methods are introduced to VANET to detect Sybil attacks, but there are still several issues that have not been resolved. In this paper, we proposed the design of a defense mechanism against Sybil attacks. This mechanism aims to be suitable for application on IoT networks that have limited resources an also considering accuracy, privacy, safety, and real-world implementations. The proposed design uses a hybrid scheme with a trust-based method. Each node has an obfuscated identity to guarantee privacy. The trust center in the form of a Road Side Unit (RSU) will give a reputation value to each identity that will be evaluated periodically when in the range. Nodes form a fully distributed network when there is no RSU. It will use a data-centric neighbor trust scheme where its neighbors will assess each node based on the exchanging data. Each node reports on suspicious nodes to the RSU for evaluation. This mechanism allows RSU to evaluate suspicious node, which decides to isolate that Sybil node out of network.

Abstract
Early childhood education in schools must be able to stimulate the development of communication skills as one of the most important aspects of development. Based on the results of preliminary observations, it was identified that learning proces in early childhood education is still dominated by the individual and paper based strategy so that the development of childrens communication is low. To optimize childrens communication skills, STEAM-PBL is applied which in its stages provides more opportunities for children to express ideas verbally. STEAM-PBL was carried out in three series with a total of 12 meetings involving 14 children aged 4-5 years and observed using an observation sheet containing a number of indicators related to communication skills. Data were analyzed using descriptive statistics supported by narrative explanations. The results showed that childrens communication skills developed very well until the end of learning.

Abstract
A reliable method of detecting tsunami generation in the ocean for effective tsunami early warning requires rapid and accurate tsunami-discriminant calculations, which include rupture duration (Tdur), the duration exceeds 50 seconds (T50ex), and the dominant period (Td) of first P-wave arrivals extracted from seismic signals induced by earthquakes of varying magnitudes. In this context, this study is thus aimed to analyze the effects of M-filter implemented on the existing Tsunami Early Warning Application (Ina-TEWA) performance in terms of accuracy in determining such discriminants. A method of real-time experiments was developed in this study, where tsunami parameters obtained before and after M-filter implementation were analyzed for the number of false warnings issued. A total of 300 Indonesian events striking regions throughout the country with a range of magnitudes from 5.0 to 7.9 during 2018-2019 years were examined. The results showed that prior to M-filter installation 15 of all cases considered were falsely issued, confirming for a total of 95% assessment being adequately accurate. However, accuracy in the Ina-TEWA performance was found to improve as false alerts reduce to zero when M-filter was introduced, implying a 100% level of accuracy. Hence, the use of M-filter in the Ina-TEWA makes its performance better, providing with reduction in false warnings and hence improved accuracy.

Abstract
Penelitian ini bertujuan untuk mempelajari pengaruh penggunaan energi dan air pada bangunan yang menerapkan system green roof. Pengambilan data penelitian menggunakan metode deskriptif kualitatif dan perbandingan terhadap bangunan konvensional. Hasil dari penelitian ini diharapkan dapat memberikan informasi mengenai green roof dan manfaatnya sehingga dapat dijadikan pertimbangan dalam membuat bangunan yang ramah lingkungan. Karena selain ramah lingkungan faktor lain yang sangat diperhatikan dalam pembuatan bangunan dengan system green roof adalah faktor ekonomi, karena dapat menghemat biaya pada penggunaan listrik dan air.

Abstract
Penyediaan air bersih belum sepenuhnya merata di Indonesia. Masyarakat di beberapa daerah khususnya pedesaan harus mencari sumber air untuk memenuhi kebutuhan sehari-hari. Itulah yang dialami masyarakat desa laang tanduk yang bermukim di dataran tinggi dengan sumber air yang tidak terjamin kebersihannya. Maka dari itu, pemerintah merencanakan reservoar dan jaringan distribusi yang dinilai mampu untuk memenuhi kebutuhan masyarakat setempat. Namun, perlu untuk menganalisa kembali perencanaan yang ada untuk memastikan kebutuhan masyarakat telah tercukupi dan karena sifatnya yang tidak hanya melihat kualitas dan kuantitas melainkan kontiniuitas, melihat penduduk yang terus bertambah sehingga dipertimbangkan kebutuhan masyarakat di tahun mendatang. Hasil analisa menyatakan, pada tahun 2017 kebutuhan air sebesar 5,103 lt/dt di jam puncak dengan kapasitas reservoar 50 m³ dan terdiri dari pipa berdimensi 2,5-8 inci. Adanya pertumbuhan penduduk menyatakan kebutuhan air meningkat menjadi 9,548 lt/dt dengan kapasitas tampungan 95 m³ dan pipa berdimensi 3-12 inci. Akibat perbedaan elevasi dan terdapat kehilangan energi yang signifikan, menyebabkan penggunaan pompa di 2 titik. Dengan ini, disimpulkan bahwa perencanaan yang ada telah memenuhi kebutuhan masyarakat akan air bersih namun di tahun mendatang pada tahun 2030, baik kapasitas reservoar maupun sistem transmisi yang diwadahi oleh pipa tidak relevan lagi untuk digunakan sehingga kapasitas reservoar dan saluran transmisi harus diperbesar.

Abstract
Konsep integrated saat ini sering digunakan pada bangunan-bangunan berkonsep Transit Oriented Development untuk memberikan kemudahan mengakses moda transportasi dan bangunan terdekat. Hal ini juga harus didukung oleh kenyamanan agar masyarakat mau untuk menggunakan transportasi umum. Faktanya konsep integrated tidak hanya sekedar membangun jembatan penghubung dan memberikan akses menuju dua tempat. Tulisan ini menggunakan metode komparatif terhadap pembanding beberapa mixed-use di kawasan Blok M Plaza, BSD City dan PGC. Variabel yang diamati terdiri dari fungsi jembatan, peneduh, fasilitas, posisi moda transportasi dan integrasi antar bangunan. Hasil menunjukkan bahwa kriteria konsep integrasi bangunan memperhatikan Jembatan penghubung yang memiliki peneduhan untuk menghindari hujan dan panas, bangunan yang berorientasi pada moda transportasi, pembatas jalan yang ramah disabilitas dan menggunakan tanaman sebagai pagar alami.

Abstract
Bubuk terak nikel merupakan limbah dari produksi peleburan bijih nikel yang sudah dikelola oleh PT. INDOFERRO, dengan kadar Fe yang terbilang kecil. Laporan Kemenperin 2018 mendapati bahwa dari total 40 ton produksi nikel per tahun, 30 ton akan menjadi limbah atau terak. Sehingga penumpukan limbah terak nikel terjadi di Sulawesi Tenggara, limbah yang dibiarkan menumpuk akan berbahaya bagi lingkungan. Penelitian ini bertujuan untuk mempelajari karakteristik dari material non-ferrous pada beton geopolimer. Beton geopolimer merupakan inovasi beton yang ramah lingkungan dan dapat dikategorikan sebagai green concrete, karena tidak menggunakan semen sama sekali sehingga emisi CO₂ akibat pembuatan semen dapat dikurangi. Bahan-bahan seperti abu terbang dan terak diketahui memiliki sifat pozzolanic, namun diperlukan prekursor yang dapat mengaktifkan ikatan Si-O-Al sehingga reaksi ikatan terjadi, prekursor tersebut ditemukan di dalam campuran NaOH dengan Na₂SiO₃. Pada penelitian ini bubuk terak nikel akan diuji secara fisik dengan botol Le Chatelier Standard dan pengujian kimia XRF. Beton geopolimer dengan komposisi 50% abu tebang 50% bubuk terak nikel akan diamati, dengan kadar molaritas 6 M dan 12 M dan rasio Na₂SiO₃ : NaOH adalah 2,5 : 1. Benda uji akan melalui proses rest period selama 24 jam kemudian proses curing dengan cara steam dengan suhu 60°C selama 24 jam. Kuat tekan diumur 28 hari pada beton geopolimer didapatkan sebesar 55,97 MPa dengan molaritas 12 M, sedangkan pada kadar molaritas 6 M sebesar 49,97 Mpa, hal ini terjadi akibat kadar alkalinitas dalam larutan alkali.

PENERAPAN KONSEP ARSITEKTUR NARATIF PADA OBJEK JEWISH MUSEUM DI BERLIN APPLICATION OF THE NARATIVE ARCHITECTURAL CONCEPT IN THE JEWISH MUSEUM OBJECT IN BERLIN Laudza Az Zahra*1, Ady R. Thahir*2, Sri Tundono*3 *ˡ Mahasiswa Program Studi Arsitektur, Universitas Trisakti, Jakarta *² Dosen Program Studi Arsitektur, Universitas Trisakti, Jakarta Jurusan Arsitektur, Universitas Trisakti, Jakarta *e-mail : ˡ arch.laudza@gmail.com, sri.t@trisakti.ac.id, Jl. Kyai Tapa No. 1 Grogol, Jakarta Barat ABSTRAK Manusia dapat mempersepsikan bangunan melalui berbagai macam pendekatan. Salah satu konsep pendekatan yang cukup umum diterapkan pada konstruksi museum adalah konsep arsitektur naratif. Penerapan konsep arsitektur naratif pada museum dapat membantu museum menarasikan makna dari museum tersebut terhadap pengunjung museum. Objek yang akan digunakan sebagai studi kasus pada jurnal ini adalah Jewish Museum yang terletak di Berlin. Metode yang digunakan dalam tulisan ini adalah metode kualitatif, dengan cara mengambil satu preseden dan menganalisa unsur arsitektur naratif yang terdapat pada museum tersebut dengan menggunakan literatur Narrative Architecture yang ditulis oleh Nigel Coates. Fokus paper ini adalah untuk mengidentifikasi unsur arsitektur naratif pada Jewish Museum di Berlin, dan memberikan kesimpulan apakah Jewish Museum Berlin layak dikategorikan sebagai museum yang menerapkan konsep arsitektur naratif atau tidak.
