Abstract

The performance of a power plant unit is strongly influenced by various aspects, one of which is very determined by how the combustion process occurs in the combustion chamber, because it can affect the efficiency of the power plant itself, especially in the efficiency aspects of the boiler combustion process. To find out the efficient operation of the boiler, the operator as the holder of the power plant must understand what the combustion process is like in it. Good combustion will always require the right combination of fuel and air (oxygen). From the results of the research that has been done, it can be seen that if the actual amount of air flow needed for the combustion process is closer to the ideal air flow value it will indirectly increase the combustion efficiency value of the boiler.

Abstract

Alih fungsi lahan di Jalan A. Yani km.6 Banjarmasin sampai dengan km.17 Kabupaten Banjar merupakan fenomena ruang spatial yang menarik untuk diamati. Lahan sawah produktif mulai berubah fungsi menjadi lahan terbangun untuk kegiatan ekonomi komersial. Pembangunan perumahan permukiman, baik perumahan massal, swadaya maupun rumah toko (ruko) merupakan tuntutan kebutuhan masyarakat. Kondisi ini tentu saja membentuk pola-pola ruang tertentu.Penelitian ini bertujuan mengeksplorasi ruang permukiman dan menganalisis kecenderungan yang akan terjadi pada masa mendatang. Analisis dilakukan secara kualitatif deskriptif menggunakan tiga variabel yaitu kerangka kawasan, layout ruang dan bangunan dan moda angkutan didapatkan pola permukiman yang dimaksud. Koridor jalan A.Yani lebih didominasi pola linear dan kemudian beberapa kawasan mengalami perkembangan cabang jalan dan ranting jalan yang selanjutnya membentuk pola seperti pola tulang ikan. Terdapat 149 buah cabang jalan dan yang paling dominan terdapat di km.7 dan km.8 dan km.14. Semakin dekat dengan pusat pertumbuhan maka semakin banyak jumlah cabang jalan. Jika dilihat dari layout ruang dan bangunan maka terdapat 6 model layout ruang yang terbentuk di antara bangunan, di antara bangunan dan moda angkutan transportasi dan di antara bangunan dan lingkungan.Diperkirakan koridor jalan A.Yani dari km.6 sampai km.17 akan berkembang 4 pola permukiman yaitu pola linear, grid, cluster dan amorf. Selain itu dampak negatif yang dikhawatirkan terjadi adalah munculnya squatter settlement (permukiman ilegal) dan slum area (kawasan kumuh) yang mengikuti perkembangan kawasan perdagangan, jasa dan kegiatan ekonomi. Untuk mengatasi ini perlu dilakukan penataan kapling sebelum terjadi pembangunan yang besar-besaran. Kasiba dan Lisiba merupakan konsep yang efektif untuk mengendalikan pembangunan fisik dan menjamin ketersediaan ruang terbuka permukiman.
