Abstract

Kondisi angkutan umum di Kota Gianyar sedang terpuruk. Masyarakat enggan menggunakan angkutan umum yang tidak memberikan pelayanan yang memadai dan lebih memilih kendaraan pribadi sebagai alat angkut dalam melakukan perjalanan. Akibatnya, terjadi peningkatan kendaraan pribadi, baik roda dua maupun roda empat yang melintas pada ruas-ruas jalan Kota Gianyar. Peningkatan kepemilikan kendaraan pribadi ini tidak sebanding dengan perluasan prasarana jalan, sehingga terjadi kemacetan akibat ketimpangn antara supply dan demand. Tujuan penelitian ini untuk menganalisis kinerja angkutan umum yang dipengaruhi oleh kualitas pelayanan angkutan umum dan kinerja rute trayek. Metode pengumpulan data dalam penelitian ini dengan menyebarkan kuesioner kepada 400 responden, dan observasi langsung ke lapangan, yaitu pada rute trayek Batubulan-Ubud, sebagai data primer. Kuesioner memuat serangkaian pernyataan yang meminta persepsi responden sebagai jawaban. Data sekunder berupa daftar rute jalan yang melayani trayek ini. Uji validitas dan reliabilitas dilakukan terhadap data awal sebanyak 30 kuesioner, untuk mengetahui keakuratan dan kehandalan instrumen. Selanjutnya dilakukan uji t (parsial), F (simultan), model regresi dan koef. determinasi (R2). Hasil penelitian menunjukan bahwa kondisi eksisting rute Trayek Terminal Ubud-Batubulan yang didapatkan dari hasil penyebaran kuesioner yakni masyarakat merasa kurangnya keandalan dalam pelayanan angkutan umum serta daerah pelayanan trayek tidak mencukupi kebutuhan. Pelayanan angkutan umum (X1) berpengaruh positif dan signifikan terhadap kinerja angkutan umum (Y) pada trayek Batubulan-Ubud dengan nilai t hitung > t tabel (7,865 > 1,966). Kinerja trayek (X2) berpengaruh positif dan signifikan terhadap kinerja angkutan umum (Y) pada trayek Batubulan-Ubud dengan nilai T hitung > T tabel (6,847 > 1,966). Pelayanan angkutan umum (X1) dan kinerja trayek (X2) secara simultan berpengaruh positif dan signifikan terhadap kinerja angkutan umum (Y) pada trayek Batubulan-Ubud dengan nilai F hitung > F tabel (209,162 > 3,02). Adapun persamaan regresi yang didapet yakni:Y=3,640 + 0,290X1 + 0,294X2. Berdasarkan hasil tersebut maka untuk meningkatkan kinerja angkutan umum maka perlu kebijakan maupun regulasi untuk mengoptimalkan pelayanan angkutan umum dan meningkatkan kinerja trayek pada rute trayek Batubulan-Ubud.

Abstract

Urban farming merupakan salah satu usaha di bidang pertanian yang cukup banyak dilakukan di perkotaan dengan memanfaatkan lahan lahan terbuka di sekitar masyarakat. Metode pertanian ini cocok karena tidak diperlukan area yang luas dan dapat dilakukan tanpa media tanah. Salah satu metode urban farming yang banyak diminati oleh masyarakat, yaitu metode hidroponik atau penanaman tanpa menggunakan media tumbuh dari tanah. Metode pertanian hidroponik menggunakan lahan lebih efesien dan memiliki manfaat bagi lingkungan seperti, mampu mengurangi polusi udara, menjadikan udara lebih sejuk dan mampu meningkatkan kadar oksigen O2 di udara. Selain pengembangan teknologi pertanian metode hidroponik, budidaya ikan lele dengan metode bioflok, budidaya maggot dan pengolahan sampah atau limbah organik menjadi eco-enzyme juga menjadi tren baru yang diminati oleh masyarakat. Pendekatan penelitian yang digunakan adalah pendekatan deskriptif kualitatif. Pendekatan ini dipilih dengan tujuan untuk dapat menjelaskan dan menjawab secara lebih rinci permasalahan yang akan diteliti. Metode penarikan kesimpulan menggunakan metode induktif dengan melihat hal-hal khusus kemudian menarik sebuah kesimpulan baru yang lebih umum. Pusat Pelatihan Urban farming di Kabupaten Badung mengambil konsep edukasi dan wisata dengan tema Green Architecture seperti penggunaan bahan material ramah lingkungan, penggunaan energi terbarukan, tampilan fasad bangunan menggunakan material alam dengan penambahan vegetasi disekitarnya dan konservasi penggunaan air seperti pengolahan kembali limbah air pada bangunan. Bangunan Pusat Pelatihan Urban farming di Kabupaten Badung diharapkan tidak hanya bermanfaat bagi civitas didalamnya tetapi mampu bermanfaat terhadap lingkungan disekitarnya.

Abstract

Badung merupakan salah satu Kabupaten yang ada di Bali yang menjadi salah satu destinasi wisata yang paling banyak dikunjungi oleh wisatawan domestik maupun mancanegara. Banyak fasilitas akomodasi wisata yang dibangun di Kabupaten Badung mulai dari hotel, resort, villa, private villa, serta guest house. Salah satu langgam yang paling banyak digunakan dalam mendesain disini yakni green architecture ataupun eko arsitektur dengan memanfaatkan view yang indah di sekitar site. Pada tulisan ini penulis menggunakan 3 objek karya arsitektur yang menerapkan konsep eko arsitektur khususnya yang berlokasi di Kabupaten Badung. Tujuan dari tulisan ini adalah untuk mengetahui seberapa jauh penerapan konsep eko arsitektur pada desain bangunan. Metode yang digunakan adalah metode kualitatif deskriptif. Pada tahap pengumpulan data menggunakan metode grand tour, dengan memilih beberapa objek arsitektur berupa villa/hotel/resort yang berlokasi di badung yang nantinya akan digunakan sebagai studi kasus. Hasil dari penelitian yang menggunakan 3 kasus ini dapat disimpulkan bahwa penerapan konsep eko arsitektur pada fasilitas akomodasi wisata (hotel, resort dan villa) di Kabupaten Badung hanya sebatas pada aspek penggunaan material bangunan, desain fasad bangunan terkait pencahayaan dan penghawaan di dalam bangunan, pemanfaatan view yang ada di sekitar site, desain fasad bangunan yang mengikuti iklim setempat, serta penataan taman yang alami dan tidak banyak mengubah kondisi site. Hal-hal yang kurang diperhatikan terkait prinsip eko arsitektur adalah penggunaan teknologi yang canggih pada desain bangunan yang bertujuan mengoptimalisasi penggunaan energi yang berasal dari alam.

Abstract

Implementation planning in project management is very important. Project implementation planning is a stage applied in project management by setting goals and objectives that must be achieved and determining the policies of all technical and administrative programs so that they can be implemented. Planning the implementation of development projects uses data collection methods with library and documentation techniques, the data obtained is in the form of secondary and primary data. The implementation method in the field uses conventional and mechanical methods to maximize work, one of which is pile cap work. Pile cap is a way to tie the foundation before a column is erected at the top. This pile cap aims to make the location of the column really at the center point of the foundation so as not to cause eccentricity that can cause additional load on the foundation. The pile cap carried out in the UPT Nyitdah Tabanan Hospital IGD Building Construction project uses four types of pile caps and the implementation method in the field uses mechanical methods. The scheduling results in writing this journal use the Precedence Diagram Method (PDM) method. The total duration based on the calculation is 45 days with a Bill Of Quantity (BOQ) including 10% VAT of Rp7,645,657,919.78.

Abstract

One of the things that can damage the floor is gallon water bottles, milk bottles, shampoo bottles, detergent bottles, and other thick plastics made from organic compounds and made from high-density polyethylene (HDPE) plastic. We see an opportunity to utilize the substantial amount of plastic waste as an additional material produced by hot mixing in a flexible processing structure. lasto AC-WC mixture to determine the optimal amount of bitumen in the AC-WC mixture containing HDPE plastic additive and the AC-WC mixture containing HDPE plastic additive. An empirical approach was used in this study to add the VFB value of high density polyethylene (HDPE) plastic to the number of samples that needed to be tested to get the best bitumen content (KAO). 65 percent of the minimum requirements have been met by the VFB value. The stability value of Marshall Kao is also higher when HDPE plastic is used, with deviations of 0.50%, 1.00%, and 1.50%, respectively. The flow value meets the minimum requirement of 2 mm, despite the fact that the melting value (flow value) tends to decrease. In contrast, Kao increased the value of flexibility (MQ) by 1.00% for the 0.50n HDPE plastic mix variation, and the 1.50a variation saw a significant increase. The ideal amount of asphalt (KAO) is 5.70 percent. AC-coated asphalt concrete Gross Heavy WC, Ruston Asphalt Concrete Mix Design Result - Mounted Course uses high density polyethylene (HDPE) in the asphalt mixture at 5.70%, 0.50%, 1.00%, and 1.50% for each variation of HDPE plastic mix.

Abstract

One of the waste materials which used as an additive for concrete mixtures is Coffee skin ash. Coffee skin ash is the result of burning coffee skin in the coffee bean grinding process. This waste is abundant in the Municipio Ermera (one of the big District in Timor-Leste), but its very limited to use. Municipio Ermera is a land and the center of coffee plantations in Timor-Leste. For this reason, an idea about use of wasted coffee skin ash is needed without causing damage to the environment. In this study, coffee skin ash used from Ermera area with a ratio of 0%, 5%, 10%, and 15% from cement weight. The purpose of this study to find how to compare the compressive strength of concrete between normal concrete and added coffee skin ash from Ermera. This method used in this study is experimental study and for each classification were made 5 specimens. The results of this research and analysis it can be concluded the compressive strength value of concrete using coffee skin ash as a partial replacement for cement composition with normal concrete has a significant comparison. Where it was found that concrete using coffee skin ash with composition of 5%, 10%, and 15% had a higher compressive strength value to concrete without coffee skin ash. The comparison of the increase in compressive strength that occurs is around 16% to 19,6%.

Abstract

The development of development in urban areas will also have an impact on the land cover area. Efforts that can be made to determine urban development are by looking at land cover information through land cover maps. Land cover data can provide information in studying climate change and understanding the relationship between human activities and climate change. The method used is descriptive with interpretation of Landsat 8 imagery, using a Geographic Information System (GIS). Normalized Diffrence Vegetation Index (NDVI) is a calculation on an image that is used to determine the level of greenery as the initial division of vegetation and land cover areas. Klungkung Regency in the last five years continues to experience changes. The area of paddy fields in Klungkung Regency in the past five years tends to decrease. In 2013 the area of paddy fields was 3,843 Ha, reduced to 3,779 Ha in 2017. Based on the results of Landsat 8 satellite imagery, from 2016 to 2021 there was a decrease in the area of vegetation density by 35.11 km2 or 11.39% while the area of residential land cover increased by 29.98 km2 or 9.73%.

Abstract

The floriculture garden plays an important role in the preservation of plants, especially ornamental plants and also plays a role in overcoming the problem of global warming and contributes to the provision of urban green open spaces. The unwise exploitation of the existing biodiversity is one of the reasons for increasing greenhouse gas emissions in Indonesia. In addition, there is also a phenomenon of reduced open space in urban areas due to land conversion due to the high population growth in Indonesia. This is in accordance with the current condition of the city of Denpasar which has become an urban city with the most populous population in the province of Bali. This phenomenon makes the area of ​​Denpasar City Public green open space less than the ideal standard. On the other hand, there are still many types of ornamental plants in Indonesia that have not been conserved. Thus, it is necessary to procure a Floriculture Park in Denpasar City to overcome the problem of the number of ornamental plants that have not been conserved, global warming that occurs, and the reduction of green open space in urban areas. This design also aims as a recreational and educational facility. The basic concepts used are recreational, conservation and educational. While the chosen design theme is a biomorphic architectural theme with sustainable forms, structures and materials. The design method used is data collection techniques in the form of library research, observation and comparative studies, as well as data processing methods, namely analysis, synthesis and transformation methods. The results of the design of the Floriculture Park in Denpasar City are explained into three principles of biomorphic architecture. The first principle is the principle of form, namely the form of mass based on ecology and metaphor of natural forms. The second principle is the principle of structure and material, its application is the use of structures with organic shapes, while in terms of materials the application is by selecting natural (local) materials and materials that support a curvilinear shape. The third principle is the principle of sustainability, the application of which is to maximize the use of natural energy into buildings.
