Abstract

The tofu industrial center of Tegalpasangan - Pakis - Malang is one of the large tofu industrial centers in Malang Regency, where in the tofu industrial center there are no less than 20 tofu industries, most of which are Micro, Small and Medium Enterprises (MSMEs) with a workforce of 2 - 4 people with an average production capacity of 2-5 quintals of soybeans per day. Like other cottage industries, tofu is produced manually without mechanical equipment, and there is little attention to good, healthy production methods. Likewise, without the existence of a wastewater treatment plant (IPAL) to treat waste water generated from the production process, which results in pollution of the aquatic environment. Community service activities aim to increase the knowledge, understanding and skills of partners (tofu industry owners) in producing tofu and treating wastewater properly and healthily. Technical guidance is provided in the form of GMP (Good Manufacturing Product) training, HACCP (Hazard Analitycal and Critical Control Point), waste treatment and provision (grant) of WWTP equipment. The results of PkM activities show that the provision of training and IPAL grants provides significant benefits for the knowledge and skills of partners, especially in handling waste water produced from the tofu industry so that it can reduce environmental pollution.

Abstract

Limbah cair industri tepung tapioka mengandung bahan-bahan organik dengan kosentrasi yang tinggi yaitu COD sekitar 7.000 - 30.000 mg/L dan BOD sekitar 3000-6000 mg/L sehingga memiliki potensi untuk digunakan sebagai bahan baku pembuatan biogas. Dengan menggunakan fermentasi secara anaerobik di dalam reaktor (digester), limbah cair industri tapioka mengalami proses dekomposisi menjadi biogas oleh mikroorganisme anaerob. Beberapa teknologi pengolahan limbah cair tapioka menjadi biogas antara lain, digester sistem batch, covered lagoon anaerobic reactor (CoLAR), Continuous Stirred Tank Reactor (CSTR), CSTR dengan Resirkulasi Padatan, Plug Flow Reactor, FBR (Fixed Bed Reactor), Expanded Bed Digester, dan UASB (Upflow Anaerobic Sludge Blanket). Untuk meningkatkan efisiensi pengolahan terdapat beberapa faktor yang mempengaruhi, antara lain: pemilihan starter, konsentrasi awal substrat, suhu operasi, tingkat keasaman (pH) dan rasio perbandingan C/N. Beberapa studi menunjukkan bahwa semakin tinggi konsentrasi awal substrat maka semakin tinggi kualitas dan kuantitas biogas yang dihasilkan. Berdasarkan hasil kajian menunjukkan bahwa metode covered lagoon anaerobic reactor (CoLAR) memiliki efektifitas yang tinggi untuk menghasilkan biogas dari limbah tapioka. Pada konsentrasi awal substrat sebesar 9.011 mg/L mampu menghasilkan biogas mencapai 485,4 m3 /hari.

Abstract

Pada industri pengolahan rumput laut digunakan kaporit untuk penghilangan bakteri pada proses perendaman, sehingga limbah yang dihasilkan mengandung klor dengan kadar tinggi yang apabila dibuang akan mencemari lingkungan. Tujuan penelitian ini adalah untuk menurunkan kadar klor dalam limbah cair industri pengolahan rumput laut melalui proses pemanasan dan penambahan amonia ke dalam limbah cair industri pengolahan rumput laut. Penelitian ini dilakukan dengan beberapa tahapan, yaitu mula-mula air limbah dipanaskan dengan variabel suhu yaitu 28°C, 30°C, 35°C dan 40°C kemudian air limbah diberi penambahan amonia dengan variabel % penambahan sebesar 1%, 2%, 3 % dan 4%. Pada penelitian ini dapat diambil kesimpulan semakin tinggi suhu dan semakin besar penambahan % amonia maka semakin besar % penurunan kadar klor aktif dimana % penurunan klor aktif maksimal sebesar 98,6% yang dicapai pada suhu 40°C dengan % penambahan amonia sebesar 4%. Pada penelitian ini diambil kesimpulan bahwa semakin tinggi suhu dan semakin besar konsentrasi amonia yang ditambahkan maka semakin sedikit klor yang tersisa dalam limbah.

Abstract

Pengolahan limbah pada suatu industri pengolahan rumput laut dilakukan secara fisik-biologi-kimia, dimana pengolahan secara kimia menggunakan proses adsorpsi dalam bentuk  granular karbon aktif. Namun dalam penggunaan granular karbon aktif dinilai kurang efektif karena membutuhkan lahan dan kolom adsorpsi yang cukup besar. Pada sisi lain, proses adsorpsi menggunakan nano adsorben memberikan efektifitas tinggi dalam menurunkan polutan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi nano karbon aktif terhadap penurunan COD, BOD, pH, dan kekeruhan pada air limbah industri pengolahan rumput laut. Percobaan dilakukan dalam keadaan tersuspensi dengan menggunakan nano adsorben karbon aktif berbentuk powder.  Variabel yang digunakan adalah konsentrasi nano karbon aktif sebesar 200 ppm; 600 ppm; dan 1000 ppm dengan lama adsorpsi yaitu 8 jam; 13 jam; dan 18 jam. Hasil penelitian menunjukkan bahwa konsentrasi nano karbon aktif 1000 ppm dengan lama adsorpsi 13 jam dapat menurunkan secara maksimal konsentrasi COD sebesar 36%, BOD sebesar 88% dan pH 6%, sedangkan kekeruhan sebesar 41% pada konsentrasi nano karbon aktif 200 ppm dengan lama adsorpsi 8 jam.
