The increasing number of residents demands the provision of settlement facilities and infrastructure. Limited land is an obstacle to the development in the horizontal direction, especially the use of green open land which will cause land conversion. The limitation of the building height regulated by local regulations, as well as the local wisdom, namely vertical holiness can be a challenge related to the idea of building multi-storey buildings. When you want to enter the lower floors of the building, there is a feeling of doubt because there are other residents on the upper floors who step over. This study aims to reveal the relationship of vertical holiness with multi-storey building design and formulate vertical holiness as an effort to implement it in a design so that it can be accepted by the community. This study uses a methodology to examine the problem by interviewing the stakeholders and filling out the questionnaire, therefore, the relationship between vertical holiness and multi-storey building design can be obtained. The results of the study clearly confirm that there is indeed a correlation between vertical holiness and multi-storey building design. Thus, the design should pay attention to this vertical holiness. The study also encourages that the formulation of vertical holiness should be legally stated in regulation so that it is easily understood and accepted by the community.

Peningkatan jumlah penduduk dan pesatnya perkembangan pariwisata di Kota Denpasar menyebabkan berkurangnya lahan sawah dan meningkatnya lahan bukan pertanian. Tujuan penelitian ini yaitu menganalisis keterkaitan aspek demografis terhadap penggunaan lahan Kota Denpasar dan merumuskan strategi jumlah penduduk dan penggunaan lahan di Kota Denpasar. Metode yang digunakan dalam penelitian ini yaitu metode kuantitatif dengan melakukan analisis tren dan deskriptif komparatif. Hasil penelitian yaitu peningkatan jumlah penduduk Kota Denpasar cenderung meningkatkan penggunaan lahan bukan pertanian (khususnya pemukiman) dan menurunkan penggunaan lahan sawah selama kurun waktu 2011 sampai 2016. Hal tersebut karena meningkatnya kebutuhan pemukiman, belum adanya aturan RDTR dan zonasi, dan adanya aturan batasan ketinggian bangunan. Rumusan strategi yang dapat digunakan terkait jumlah penduduk dan penggunaan lahan di Kota Denpasar, yaitu Pemerintah Kota Denpasar harus konsisten dalam menegakkan peraturan, melakukan pengendalian penduduk, mulai merencanakan pengembangan bangunan vertikal dengan syarat tertentu agar tetap dapat mengakomodasi aturan batasan ketinggian bangunan, serta membuat aturan terkait perlindungan lahan pertanian berkelanjutan.

Penelitian ini bertujuan untuk mengetahui pengaruh NaCl dan MgSO4 terhadap kuat tekan dan kuat tarik belah batu padas buatan yang memiliki karakteristik menyerupai batu padas alam khususnya batu padas alam Kelating dan Kerobokan. Dasar pertimbangan penelitian ini adalah upaya mempertahankan arsitektur tradisional Bali dan pemanfaatan pozzolan alam sebagai bahan utama dalam pembuatan batu padas buatan. Penelitian ini menggunakan pozzolan alam, tanah liat, kapur dan semen sebagai bahan dasar. Pemilihan bahan dasar tersebut berkaitan dengan karakteristiknya yang hampir sama dengan batu padas alam Kelating dan Kerobokan. Benda uji dibuat sebanyak 360 buah yang terdiri dari batu padas alam dan batu padas buatan. Benda uji sebanyak 180 buah berbentuk kubus ukuran 8x8x8 cm untuk uji kuat tekan dan 180 buah berbentuk silinder ukuran 7,5x15 cm untuk uji kuat tarik belah. Benda uji dibuka dari cetakannya pada umur 1 hari kemudian dibiarkan mengering selama 2 hari. Pada umur 3 hari benda uji direndam dalam air biasa sampai umur 28 hari. Kemudian pada umur 29 hari benda uji direndam dalam larutan NaCl dan MgSO4 sampai umur 60 hari dan 90 hari. Perendaman benda uji dilakukan secara terpisah antara asli, buatan, dan juga jenisnya untuk diteliti lebih lanjut kandungan kimia yang lepas dan terlarut dalam larutan perendam. Bahan kimia NaCl dan MgSO4 dicampur dengan air biasa sampai mencapai konsentrasi yang telah ditetapkan yaitu 0%, 1%, 2%, dan 3%. Pengujian kuat tekan dan kuat tarik belah dilakukan pada umur benda uji 28 hari, umur 60 hari setelah perendaman selama 31 hari dan umur 90 hari setelah perendaman selama 61 hari dengan larutan NaCl dan MgSO4. Hasil penelitian ini menunjukkan bahwa kuat tekan batu padas buatan baik batu padas sejenis Kelating maupun Kerobokan lebih rendah dari batu padas aslinya. Sedangkan kuat tarik belahnya lebih tinggi pada batu padas buatan dibandingkan dengan batu padas aslinya. Penurunan kuat tekan tersebut disebabkan karena tingkat reaktifitas butiran penyusun batu padas buatan yang rendah dan teknis perawatan benda uji pada umur 3 hari sudah direndam dalam air dimana pada saat itu kondisi benda uji masih basah. Perendaman dengan larutan NaCl dan MgSO4 dengan konsentrasi 0%, 1%, 2%, dan 3% selama 61 hari menunjukkan pengaruh yang kecil terhadap kekuatan batu padas. Hal ini dapat disebabkan karena konsentrasi larutan yang rendah, serta NaCl dan MgSO4 bereaksi lambat dengan pasta semen yang dapat berlangsung dalam beberapa bulan sampai beberapa tahun untuk mencapai keadaan yang membahayakan.

he aim of this research was to obtain the benefits of Lapindo silt as cement substitution material in fabricating paving block with the most ideal mixture composition evaluated from compressive strength and water absorption with physical quality based on PUBI-1986. Paving block were made using Lapindo silt as cement substitution with composition that were A mixture (100% PC; 0% LS), B mixture (90% PC; 10% LS), C mixture (80% PC; 20% LS), D mixture (70% PC; 30% LS), and E mixture (60% PC; 40% LS). Fabricating process of paving block started from material preparation, making mixture, molding, curing, selection, and then followed by conducting the research by compressing the paving block and obtaining the water absorption. Based from water absorption, result of this research showed that the mix D has better benefits of Lapindo silt as cement substitution material with optimum water absorption and decreasing compressive strength. This was caused by SiO2 contained in the mixture (as filler) and also supported by CaO (as a binder between materials). The small value of water absorption can also increase the durability of paving block. The best composition was D mixture, where has optimum water absorption with little decreasing in value of compressive strength.

Pada pengujian perembesan air, genteng berbahan lumpur Lapindo semuanya tahan terhadap perembesan, sedangkan genteng yang berbahan tanah liat (standar UD. BS. Super) tidak tahan. Pada uji daya serap, genteng berbahan Lumpur Lapindo memiliki daya serap yang lebih kecil jika dibandingkan dengan genteng berbahan tanah liat (standar). Abstract: A research on the use of Lapindo mud as material substituting clay in roof tile production is aimed to know whether Lapindo mud could be used as material that substitutes clay. Moreover, this research is also conducted to know the characteristics of tile constructed from Lapindo mud (burden limber, water absorption, and water infiltration), which later be compared with the characteristics of standard tile made in UD. BS. Super. There are several materials used as composition of the tile including clay, paras pollen, water, and Lapindo mud, whereas, the standard tile from UD. BS. Super uses clay as its main composition. The percentage composition of Lapindo mud contained in the new tile are 100%, 90%, 80%, 70% from the volume of clay and Lapindo mud mixture. Then, the mixture is added with paras pollen as additional material with constant percentage, that is 20% from the volume of clay and Lapindo mud mixture. There are several steps conducted in making the roof tile including mixing the materials, milling, forming, draining, combusting, and selecting. Following the processes, several tests on the characteristics of the tile including burden limber, water absorption, and water infiltration are conducted. The result of the test shows that the mixture of Lapindo mud and clay produces better quality of tile than standard tile of UD. BS. Super. On the test of burden limber, it is resulted several tiles including standard tile of UD. BS. Super, tile with composition A (100% Lapindo mud, 0% clay), composition B (90% Lapindo mud, 10% clay) in which tiles with A and B compositions are classified into tiles with quality types III-IV. While the tiles with composition C (80% Lapindo mud, 20% clay) and composition D (70% Lapindo mud, 30% clay) are classified into tiles with quality types II-III (PUBI 1986).On the test of water infiltration, the tiles, which are constructed from Lapindo mud are all waterproof. While those tiles made from clay (UD. BS. Super standard) are not waterproof. Moreover, on the test of water absorption, the tiles made from Lapindo mud are found to be having smaller water absorption compared to those that use clay as the material (standard).
