Abstract

Biofilter septic tank is one of the domestic wastewater treatment technology uses contactmedia in processing wastewater. Contact media that can be used made from plastic or localmaterial such as volcanic scoria. This research is an applied research in order to test theefectiveness of volcanic scoria as contact media. Location of this research is Badung Regency,Bali. Research conducted by built biofilter wastewater treatment unit at research locationthat have been selected by doing first step that is designing biofilter septic tank in accordancewith the location and teoritically. Wastewater from conventional septic tank at researchlocation flowed into biofilter tank and left in the certain time to grow the biofil which willprocess the wastewater. In certain time, wastewater quality was tested and counted thedecrease percentage of wastewater concentration content. The research result showed thatthe biofilter septic tank is not effective to treat wastewater effluent from conventional septictank because it can only reduce the concentration of wastewater content about 48,74%.The parameters that not comply the wastewater standard such as free ammonia, BOD5, andCOD were reduced each about 82.15%, 45.61%, and 46.04%.

Abstract

Persetujuan Bangunan Gedung (PBG) merupakan dokumen perizinan yang wajib dimiliki apabila akan membangun bangunan gedung salah satunya rumah susun. Adanya perubahan peraturan dari Undang-Undang Nomor 28 Tahun 2002 menjadi Undang-Undang Nomor 11 Tahun 2020 dimana Izin Mendirikan Bangunan (IMB) berubah menjadi PBG dan diproses melalui aplikasi Sistem Informasi Manajemen Bangunan Gedung (SIMBG) berpotensi mempersulit masyarakat dikarenakan belum secara luas mengetahui tata caranya. Balai Pelaksana Penyediaan Perumahan Jawa IV yang melakukan pembangunan rumah susun dimana penerima bantuannya wajib untuk mengurus penerbitan PBG berupaya untuk memberikan fasilitasi kepada penerima bantuan melalui pelaksanaan sosialisasi mekanisme pengajuan usulan penerbitan PBG, penyampaian kelengkapan dokumen teknis, pendampingan pengisian aplikasi SIMBG, pendampingan penerbitan dokumen lingkungan dan penilaian bangunan gedung, serta fasilitasi penerbitan sertifikat laik fungsi. Fasilitasi ini dimulai pada tahun 2023, dimana secara signifikan berpengaruh pada peningkatan jumlah PBG yang dapat diterbitkan dari sebelumnya satu atau dua dokumen per tahun menjadi enam dokumen pada tahun 2023, dimana secara persentase, PBG yang terbit sebanyak 33,33% dari total rumah susun terbangun pada tahun 2023. Selanjutnya, agar penerbitan PBG rumah susun dapat lebih meningkat, maka diperlukan konsistensi fasilitasi yang telah dilakukan.

Abstract

Bamboo and gewang midrib are two materials developed as wood substitute in the shape form of lamina products. However, the disadvantage of bamboo and gewang is susceptible to destroying organisms. This paper analyzes the effectiveness of petung bamboo and gewang midrib treatment to improve its durability against destroying organisms. This research investigated the durability of petung bamboo and gewang midrib againts subterranean termites, dry wood termites, wood rotting fungi and dry wood post powder beetles. Treatments were conducted by applying boron and CCB (copper-chrome-boron) using cold immersion and modified Boucherie methods. Durability was tested according to Indonesian Standard SNI 01-7207-2006, while retention and penetration were calculated based on weight, volume, and solution concentrations. The results showed that boron was effective to improve the durability of petung bamboo againts subterranean termites, dry wood termites, and wood rotting fungi, while its resistance againts dry wood post powder beetles, boron and CCB were equally effective. Boron was more effective to improve durability to wood rotting fungi and dry wood post powder beetles in gewang midrib, while both preservatives were similarly effective against subterranean termites and dry wood termites. It is noticably that CCB treatment changed the wood natural color. Modified Boucherie method provides high retention but low penetration level compare to immersion method.
