Get PDFPalm oil industries producing so many palm oil mill effluent (POME) and it should be processed before the waste dumped into the environment. The treatment can be decrease BOD, COD, TSS and pH value with adsorption by activated carbon. Activated carbon in this research is using materials that contains carbon and have low value; bagasses, cocopeat, and palm fruit shells. This research purposing to know absorption of activated carbon as adsorbent with decrease percentage level of BOD, COD, TSS so the results is appropriet quality standart of waste water. Process of making activated carbon through the step of dehydration with sun lighting, carbonization for 2 hours in 500oC and continued with grinding and sizing ( 60 and 20 mesh). The next step is activation of activated carbon using ZnCl2 with variations of concentration 5%; 10%; 15%; 20%; 25% for 24 hours and finally activated carbon applied in POME waste treatment.In that process is gain optimum particle size 200 mesh with ZnCl2 concentration 25% and it showed by decrease percentage level of BOD 54,14%, COD 57,09%, TSS 51,5% and pH value 7,32 in POME.

Potential of Biomass Raw Material for Biochar Production: A Review : POTENSI BAHAN BAKU BIOMASSA UNTUK PRODUKSI BIOCHAR: TINJAUAN
No full textBiochar is a porous carbonaceous material produced from the pyrolysis of biomass under limited oxygen conditions, and it has gained widespread attention for its effectiveness in environmental remediation, soil quality enhancement, and carbon sequestration. The physicochemical properties of biochar are highly dependent on the type of biomass feedstock and the production parameters applied. Utilizing biomass waste as a raw material for biochar not only addresses organic waste management issues but also produces value-added products suitable for various applications, such as pollutant adsorption, soil amendment, and alternative fuel sources. This review aims to systematically evaluate the potential of various biomass types as biochar feedstock, focusing on the influence of feedstock composition, pyrolysis conditions, and resulting biochar characteristics on its application performance. The study integrates recent findings in the literature, demonstrating that appropriate selection of biomass—such as oil palm empty fruit bunches, sugarcane bagasse, cotton shells, lignin, and red mud—can yield high-performance biochar for heavy metal remediation, synthetic dye adsorption, and renewable energy production. This review is expected to provide a scientific foundation for developing more efficient, adaptive, and sustainable biomass-based biochar production strategies
PENGARUH JENIS SUBSTRAT TERHADAP KARAKTERISTIK PUPUK ORGANIK CAIR (POC): ANALISIS pH DAN TINGGI ENDAPAN
Get PDFBanyaknya bahan organik yang dapat digunakan untuk membuat pupuk organik saat ini, diharapkan masyarakat dapat mengganti penggunaan pupuk kimia dengan pupuk organik tersebut. Pupuk organik cair mengandung makronutrien seperti fosfor, nitrogen, kalium dan mikronutrien lain yang dibutuhkan oleh tanaman, yang dapat meningkatkan nutrisi tanah. Teknik yang digunakan dalam pembuatan pupuk organik cair adalah teknik fermentasi. Pada penelitian ini bahan yang digunakan berupa air kelapa (AK), air cucian beras (ACB), gula merah (GM), dan Effective Microorganism 4 (EM4) dengan volume pencampuran yang berbeda. Adapun tujuan dari penelitian ini yaitu untuk mengidentifikasi parameter warna, aroma, pH, serta tinggi pengendapan dari pupuk organik cair. Variabel tetap pada penelitian yaitu bahan baku berupa gula merah dan EM4, sedangkan variabel bebas yaitu bahan baku air kelapa dan air cucian beras. Variasi 1 menggunakan bahan baku tambahan berupa air kelapa, variasi 2 menggunakan bahan air cucian beras, dan variasi 3 menggunakan air kelapa dan air cucian beras dengan perbandingan volume 1:1. Pada penelitian ini proses fermentasi telah dilakukan selama 12 hari. Berdasarkan hasil data pengamatan terlihat bahwa perbandingan pupuk organik cair yang terbaik ditunjukkan oleh variasi 1 dimana menggunakan bahan baku berupa air kelapa
Removal of COD, TDS and Ammonia (NH3-N) in Produced Water with Electrochemical Using Aluminum (Al) and Iron (Fe) Electrode
Get PDFThe activities of the oil and gas industry have the potential to cause pollution for the environment. This pollution can arise due to the production of petroleum processing, storage, and industries that use petroleum. Produced water is the largest liquid waste generated by these activities. The number will increase as long as a field where exploration continues to produce. In this study, an electrochemical method using Al-Fe electrodes with the addition of 1 g/L NaCl as an agent to provide chlorine as an oxidation mediator to accelerate NH3-N removal in produced water. Chemical reactions that occur during the electrochemical process as driving force, the reduction process is specific with conductive and active electrochemical substances then can manipulated with potential (voltage) and current time. A combination of an electrode is using aluminum and iron electrode plates with each thickness 0.1mm. The voltage variations during the process were 3, 6, 9, and 12V. This process is continuous, and samples are taken every 45, 90, 135, 180, and 225 minutes. The results showed percentage of COD removal is 53.14% from 430.25 mg/L to 201.6 mg/L, ammonia (NH3-N) removal is 91.64% from 17.71 mg/ L to 1,48 mg/L and TDS removal is 78.14% from 12670 mg/L to 2769 mg/L. 9V for 225 minutes during the electrochemical process is an optimum condition that can reduce contaminants in produced water, so the quality standards of Minister of Environment Regulation No.19 2010 are fulfilled. The electrochemical method was chosen to produce water treatment because the equipment required is simple and easy to operate and does not cause new waste
Pemberdayaan Kelompok Dasa Wisma dalam Pengembangan Pertanian pada Lahan Sempit di Desa Puo Raya, Kecamatan Tandun, Kabupaten Rokan Hulu
Get PDFEmpowerment aims to develop a potential that is owned by each individual or society. Dasa Wisma Empowerment is a PKK work program consisting of 10 – 20 houses in 1 RT, community service activities are carried out in Puo Raya Village from July to August 2022. This program aims to increase the knowledge and skills of Dasa Wisma group members about cultivation organic herbs and vegetables in a narrow area. These activities include the manufacture of organic fertilizers, training on how to plant and care for plants. After the training, it is hoped that the Dasa Wisma group will have skills in making organic fertilizers, planting and caring for organic herbs and vegetables. The selection of this program is due to the large number of narrow lands that can still be used to improve the family's economy through agricultural development. The results show that the Dasa Wisma group has been able to carry out the cultivation of organic herbs and vegetables well even though the land is narrow, as evidenced by well-developed plants and vegetables. Plants and vegetables resulting from agricultural development on this narrow land can support the family's economy because the yields are quite large.
