Limbah batik memiliki kandungan organik dan warna, yang sulit untuk digredasi. Tujuan penelitian ini mengembangkan teknologi Sequenching Batch Reactor (SBR) yang dimodifikasi dengan adsorben dari tempurung kelapa dan bamboo. Konsentrasi limbah batik awal, untuk COD sebesar 1965 mg/L, warna 1603 mg/L, TSS 1140 mg/L. Pelaksanaan penelitian terbagi menjadi dua tahap, yaitu tahap pertama limbah diolah menggunakan proses koagulasi dan flokulasi, selanjutnya tahap dua menggunakan Sequencing Batch Reactor. Pada tahap koagulasi-flokulasi, menggunakan koagulan PAC (Poly Aluminium Chloride). Sedangkan pada tahap dua yang menggunakan SBR, diatur Hydraulic Retention Time (HRT) dan berat adsorben (tempurung kelapa, bamboo dan zeolite). Hasil penelitian, didapatkan proses koagulasi dan flokulasi mampu menurunkan kandungan organic (BOD5 dan COD) pada kisaran 80%, Total Suspended Solid (TSS )26% dan warna 55%. Sedangkan pada SBR, didapatkan bahwa penambahan adsorben mengoptimalkan pendegradasian kandungan organic. Didapatkan pada HRT optimal 48 jam, jenis adsorben tempurung kelapa optimal menurunkan kandungan BOD5 sebesar 93%, COD 93.7% sebesar , TSS 81% mg/L dan warna 81% mg/L. Kata kunci: kandungan organic dan warna, koagulasi dan flokulasi, sequencing batch reactor (SBR). The organic content and color of batik wastewater make it difficult to grade. The goal of this research was to create a modified Sequenching Batch Reactor (SBR) using adsorbents made from coconut shells and bamboo. The initial concentrations of COD, color, and TSS in batik wastewater were 1965 mg/L for COD, 1603 mg/L for color, and 1140 mg/L for TSS. The research was divided into two stages, with the first stage involving the use of coagulation and flocculation processes, and the second stage involving the use of a Sequencing Batch Reactor. PAC (Poly Aluminum Chloride) coagulant was used for the coagulation-flocculation stage. Meanwhile, the Hydraulic Retention Time (HRT) and the weight of the adsorbent (coconut shell, bamboo, and zeolite) were set in the second stage using SBR. The coagulation and flocculation processes reduced organic content (BOD5 and COD) by 80 %, total suspended solids (TSS) by 26 %, and color by 55 %, according to the results. In SBR, it was discovered that adding an adsorbent improves the decomposition of organic material. The optimal type of coconut shell adsorbent reduced the level of BOD5 by 93 %, COD by 93.7 %, TSS by 81 % mg/L, and color by 81 % mg/L at an optimal HRT of 48 hours. Keywords: Organic material and color, coagulation and flocculation, sequencing batch reactor (SBR).

Limbah cair industri tahu mengandung zat organik yang tinggi seperti BOD5 dan COD sehingga perlu adanya pengolahan sebelum dibuang ke lingkungan. Salah satu alternatif pengolahan yaitu menggunakan sistem biofilter anaerob. Penelitian ini bersifat eksperimental yang bertujuan untuk mengetahui penurunan kadar BOD5 dan COD pada limbah cair industri tahu menggunakan sistem biofilter anaerob. Reaktor yang digunakan terdiri dari 2 buah reaktor dan terbuat dari kaca dengan ketebalan 10 mm. Reaktor pertama bervolume 0,081 m3 yang diisi dengan media batu kerikil setinggi 70 cm dan reaktor kedua bervolume 0,059 m3 diisi dengan media bioball rambutan setinggi 45 cm. Limbah cair industri tahu dialirkan ke dalam reaktor biofilter anaerob secara kontinyu dengan arah aliran down flow. Parameter yang diukur yaitu kadar BOD5 dan COD pada inlet maupun outlet reaktor biofilter anaerob. Reaktor 1 bermedia batu kerikil mampu menyisihkan kadar BOD5 dengan penyisihan tertinggi terjadi pada waktu operasi hari ke-4 yaitu sebesar 943,8 mg/L dan penyisihan kadar COD tertinggi pada waktu operasi hari ke-4 yaitu sebesar 1931,2 mg/L. Sedangkan pada reaktor 2 bermedia bioball rambutan mampu menyisihkan kadar BOD5 dengan penyisihan tertinggi terjadi pada waktu operasi hari ke-4 yaitu sebesar 936,7 mg/L dan penyisihan kadar COD tertinggi pada waktu operasi hari ke-4 yaitu sebesar 1856,6 mg/L. Kata Kunci : batu kerikil, bioball rambutan, biofilter anaerob, limbah tahu. Tofu industrial liquid waste contains high organic matter such as BOD5 and COD so it needs processing before being discharged into the environment. One of alternative processing is using an anaerobic biofilter system. This study is experimental which aims to determine the decrease of BOD5 and COD levels in tofu wastewater using anaerobic biofilter system. The reactor consist is 2 reactors and is made of glass with a thickness of 10 mm. The first reactor with a volume of 0.081 m3 was filled with 70 cm of gravel media and a second reactor with a volume of 0.059 m3 filled with 45 cm of rambutan bioball media. Tofu industrial liquid waste is flowed into the anaerobic biofilter reactor continuously with down flow direction. Parameters measured were BOD5 and COD levels at the anaerobic biofilter reactor inlet and outlet. The highest removal of BOD5 levels in reactor 1 with gravel media occurred on the 4th day of operation with a allowance of 943.8 mg/L and the highest removal of COD levels at the 4th day of operation was 1931.2 mg/L. Whereas the highest removal of BOD5 levels in reactor 2 with rambutan bioball media occurred on the 4th day of operation with a allowance of 936.7 mg/L and the highest removal of COD levels at the 4th day of operation with a allowance of 1856.6 mg/L.

Permasalahan yang sering terjadi pada pipa distribusi air minum adalah kehilangan air. Kehilangan air mengurangi kualitas pelayanan dan pendapatan PDAM. Studi pustaka terhadap artikel ilmiah yang relevan menunjukkan adanya peluang penerapan pengendalian kehilangan air berbasis Internet of Things (IoT). Penelitian ini bertujuan untuk mengidentifikasi peluang dan tantangan penerapan IoT untuk pengendalian kehilangan air khususnya pada PDAM sebagai operator penyelenggara. IoT berpeluang mengendalikan kehilangan air melalui tiga cara yaitu manajemen tekanan, manajemen aset, dan mempercepat waktu tanggap saat terjadi kebocoran. Tantangan penerapan IoT pada PDAM di Indonesia berkaitan dengan kelembagaan dan pembiayaan PDAM, infrastruktur jaringan pendukung, kemanan data, serta ketidakakuratan dan kesalahan data. PDAM di Indonesia berpeluang menerapkan IoT namun hendaknya harus memperhatikan tantangan-tantangan yang telah dijabarkan pada penelitian ini. Kata kunci: Internet of Things (IoT), kehilangan air, PDAM. The problem that often occurs in water distribution pipes is water losses. The water losses reduce the service quality and the revenue of PDAM. The literature reviews of relevant scientific articles show that there are opportunities for implementing water losses control based on the Internet of Things (IoT). This study aims to identify the opportunities and the challenges of implementing IoT to control water losses at PDAM as an operator. The IoT has the opportunity to control water losses in three ways: pressure management; asset management; and accelerates the response time when a leak occurs. The challenges of implementing IoT at PDAM are related to the institutionalization and financing of PDAM; supporting network infrastructure; data security; and data inaccuracies and errors.

Pengelolaan persampahan di Kelurahan Cisaranten Kulon saat ini belum optimal terlihat dari adanya masalah penumpukan sampah di rumah warga akibat keterlambatan pengumpulan sampah di wilayah pelayanan ataupun tidak adanya jadwal tetap untuk pengumpulan sampah. Untuk menangani masalah tersebut dibutuhkan peran aktif masyarakat dan aspek pembiayaan untuk menunjang upaya perbaikan, maka dilakukan analisis Willingness To Pay (WTP) terhadap peningkatan pelayanan pengelolaan persampahan di wilayah ini. Didapatkan nilai WTP total sebesar Rp 124.989.122. Faktor yang mempengaruhi nilai WTP masyarakat Kelurahan Cisaranten Kulon adalah penghasilan dan kepuasan pelayanan. Rekomendasi peningkatan pelayanan pengelolaan persampahan yang direncanakan adalah pengelolaan sampah di sumber dengan program Kang PisMan, program komposter tong, serta pemanfaatan bank sampah dan optimalisasi sistem pengumpulan sampah dengan pembuatan jadwal pengumpulan sampah rutin serta penambahan alat pengumpul.
