Therefore, proper waste management is required. The use of alum as coagulant in textile wastewater treatment is commonly used, but it is not effective enough to remove wastewater colour and reduce COD. This study aims to modify alum-based batik wastewater treatment using (i)double coagulant by combining alum - FeSO<sub>4</sub>; and (ii)coagulant-oxidizing agent with combination of alum – chlorine. This experimental study consisted of two stages, the first experiment aimed to determine the optimum composition dose of alum – FeSO<sub>4</sub> and alum – chlorine in depositing waste pollutants, reducing the colour and pH of the effluent; the second experiment aims to determine the effect of alum - FeSO<sub>4</sub> and alum - chlorine at the optimum dose in reducing the COD. The results showed that alum–chlorine in various compositions reduced colour ten times and precipitated pollutants two times better than alum-FeSO<sub>4</sub>. The optimum concentration ratio of alum:chlorine is 1:1 (1.2 g/L alum : 1.2 g/L chlorine). This dose reduced the pH to 8; depositing 0.385 g pollutants; removed 99.57% wastewater colour; and decreased COD from 686.9 mg/L to 235.53 mg/L</em></p> Dewi Hambar Sari Copyright (c) 2021 EcoNews 2021-09-30 2021-09-30 4 2 39 44 10.47826/econews.4.2.p.39-44 STRATEGI PENGEMBANGAN PETERNAKAN SAPI POTONG BERBASIS AGRIBISNIS DENGAN POLA KEMITRAAN DI KOTA PEKANBARU <p><em>This study aims to formulate a management strategy for the development of agribusiness cattle with partnership pattern in Pekanbaru city.

Due to inadequate environmental sanitation, especially in suburban areas, health problems are increasing from year to year. This study aimed to analyze the implementation of Community-Led Total Sanitation Program on a sustainable environment in the suburban settlement. This was a qualitative study with an action research approach in three districts located in the suburb of Siak River. The participants of this study were residents who lived on the banks of the Siak river and the holders of the Environmental Health Program at the Public Health Center. Data were collected through direct observation and in-depth interviews regarding the Open Defecation Free (ODF) program, handwashing with soap, household food and beverage management, household waste management, and household liquid waste management. This study found that the community-led total sanitation program in the suburban of the three sub-districts of the city of Pekanbaru was not well implemented yet, especially in the ecological aspects of the Open Defecation Free (ODF) program, waste management, and liquid waste management program. Economically, the implementation of the program by non-governmental organizations had not been supported. Socially, health workers and community leaders had provided education related to environmental sanitation and obtained a level of interpretation above 70%. Therefore, the sub-districts and health public centers are recommended to keep educating both the community and the provincial health office in terms of allocating budgetary assistance for communities who live in the suburbs of Siak River.</p> Novita Rany Copyright (c) 2021 EcoNews 2021-09-30 2021-09-30 4 2 52 59 10.47826/econews.4.2.p.52-59 Strategi Pengendalian Pencemaran Sungai Batang Lubuh di Kecamatan Rambah Kabupaten Rokan Hulu <p>Batang Lubuh River is a river which is located in Rokan Hulu Regency. With approximately 151.9 Km (94.4 miles) in length, the river divides the capital of Rokan Hulu Regency Pasir Pengaraian into two parts. Because of the strategic location of the river, which is situated in the downtown, the government utilizes it as a waterfront city that attracts tourists with the local cuisines. The water from the Batang Lubuh River is the main raw material for clean water treatment which is managed by the government of Rokan Hulu Regency and distributed to Rambah sub-district. The purposes of this research were: to find out the water quality of the Batang Lubuh River; to determine the pollutant load of the Batang Lubuh River, which comes from its watercourses, namely, Menaming, Pawan, and Kaiti; to find out the load capacity of the Batang Lubuh River. The results of this research showed that the pollution index of the Batang Lubuh River is 2.38 which means that the river is lightly polluted. The pollution load that flow into the Batang Lubuh River for TSS, BOD<sub>5</sub>, total coliform, and oil and grease are 0,1350 mg/second; 0,0461 mg/second; 11,601 MPN/second and 0,0291 mg/second respectively, whereas the load capacity for TSS, BOD<sub>5</sub>, total coliform, and oil and grease in the Batang Lubuh River are 0,0412 mg/second; 0,0353 mg/second; 633,0638 MPN/second and 0,0743 mg/second respectively. Based on the findings, it can be stated that the Batang Lubuh River is not capable of purifying itself from the pollutant load such as TSS, BOD<sub>5</sub>, and oil and grease because the amount of pollutant load found in the river is bigger than the load capacity. However, the amount of total coliform found in the Batang Lubuh River is bigger than the pollutant load which means that the river still has the capability to recover itself from the pollutant load that flow into it. Based on the results of the model analysis using analytical hierarchy process (AHP), the alternatives found are as follows: 0.313 for supervision and monitoring, 0.288 for counseling/socialization, 0.203&nbsp; for &nbsp;stakeholder coordination and 0.195&nbsp;for law enforcement with the inconsistency value of 0.03.</p> Lydia Anna Oliza Rifardi Rifardi Zulkifli Zulkifli Copyright (c) 2021 EcoNews 2021-09-30 2021-09-30 4 2 60 65 10.47826/econews.4.2.p.60-65 PENGARUH AIR BERSIH DAN STATUS EKONOMI TERHADAP KEJADIAN STUNTING DI WILAYAH KERJA PUSKESMAS TAPUNG HILIR II <p><em>Infant and toddler mortality rates due to diseases that can be prevented by immunization still show quite high rates.
