Abstract

The large number of cattle breeders in Indonesia has positive and negative values. Cattle farmers generally produce livestock waste such as cow rumen. Cow rumen can be used as a starter for alternative biogas energy production, and cabbage vegetable waste has the potential to be used as raw material for making biogas, because it contains nutrients such as crude protein (PK) 22.47%, crude fat (LK) 3.05%, crude fiber (SK) 12.09%, dry matter 10.22% and extract material without nitrogen 34.96%. Apart from that, in this research cow rumen and EM4 were also used as starters for the anaerobic fermentation process. The cow's rumen contains methane bacteria, namely Methanosarcina sp, and the cow's rumen also contains quite high levels of organic compounds with a COD value of 17,183 mg/l. Effective Microorganisms (EM4) are bacteria whose function is to accelerate the degradation process of organic materials. The aim of this research is to design a biodigester, and carry out biodigester design trials. The research methods carried out are COD analysis, CH4 analysis and pH analysis. The results showed that the percentage of CH4 increased in a mixture of 100% cow rumen, because the total COD value in the substrate was directly proportional to the addition of the cow rumen composition. This can be seen from the total COD in 100% beef rumen starter of 1175 ppm.

Abstract

Crude palm oil (CPO) adalah minyak nabati yang dapat digunakan sebagai bahan baku pembuatan biodiesel. Namun, pembuatan biodiesel dari CPO terkendala kandungan asam lemak bebas (ALB) yang cukup tinggi. Rata-rata kandungan ALB pada CPO adalah 3-5%. Selain itu proses pemurnian CPO yang cukup panjang menambah biaya produksi biodiesel. Gliserolisis adalah metode pemurnian CPO yang sekaligus menurunkan kandungan ALB dengan menggunakan gliserol sebagai prekursor utama. Pada penelitian ini telah dilakukan reaksi gliserolisis CPO dengan tujuan menurunkan ALB hingga < 2%, sehingga dapat dijadikan sebagai bahan baku pembuatan biodiesel. Gliserol yang digunakan berasal dari gliserol mentah produk reaksi transesterifikasi dan juga gliserol komersial sebagai pembanding. Hasil penelitian menunjukkan pada rasio molar CPO:gliserol mentah 1:0,5, 1:0,75, 1:1, dan 1:1,5 pada waktu reaksi 60 menit dan 1% katalis terjadi penurunan ALB sebesar 78,7%, 81,5%, 84,0%, dan 94,0%. Sedangkan untuk gliserol komersial dengan variasi yang sama, terjadi penurunan ALB sebesar 87,4%, 89,3%, 90,6%, dan 96,7%. Telah dilakukan juga gliserolisis pada rasio molar 1:1 untuk waktu reaksi 30 menit dan katalis 0,5% dan 0,75% terjadi penurunan ALB 39,5% dan 55,3%. Kemudian untuk rasio molar dan konsentrasi katalis yang sama pada waktu reaksi 45 menit didapatkan penurunan ALB 47,2% dan 60,2%. Hasil penelitian menunjukkan bahwa gliserolisis menggunakan gliserol mentah dapat menurunkan ALB CPO sesuai dengan standar bahan baku biodiesel.

Abstract

Corrosion is a decrease in the quality of a metal material caused by a reaction with the environment. Reducing the corrosion rate on steel can be done by adding an inhibitor. Papaya leaf extract (Carica papaya.L) can be used as a corrosion inhibitor by immersion method. The effect of inhibitor on corrosion rate had been studied using weight loss method, potentiodynamic polarization method, and observation of steel surface using photooptic. It was found that corrosion rate decrease with increase concentration of papaya leaves extract. The highest inhibiton efficiency is 87.8% in 0.2 M hydrochloric acid with 2% concentration of papaya leaves extract. Potentiodynamic polarization method showed that papaya leaves extract decrease corrotion current. Inhibiton efficiency reached 81.58% in 2% extract concentration in which corrosion current decrease from 0.0266 mA/cm2 to 0.0049 mA/cm2. Analysis of photooptic showed that there is difference on steel surface corroded in hydrochloric acid with inhibitor and without it.

Abstract

Tujuan dari PKM (Program kemitraan Masyarakat) ini adalah memperkuat kualitas dan meningkatkan kuantitas Rak Pengering kopi Arabika Sirukam melalui penerapan inovasi rak pengering dengan sistem pengontrolan waktu. Metode penyelesaian permasalahan menggunakan metode struktural dan metode pendekatan fungsional. Metode struktural dalam bentuk perancangan dan fabrikasi rak pengering sistem pengontrolan waktu sedangkan metode pendekatan fungsional dilakukan dalam bentuk indentifikasi permasalahan dan pembuatan SOP pengeringan fullwash dan semiwash, Politeknik ATI Padang melakukan implementasi dan pelatihan, sampai pada pendampingan penerapan pengeringan yang baik. Hasil kegiatan telah diproduksi luaran dalam bentuk rak pengering kopi sistem pengontrolan waktu dan SOP pengeringan fullwash dan semiwash. Inovasi sistem pengontrolan waktu pada rak pengering kopi memilki banyak keunggulan dibandingkan rak konvensional biasa.

Abstract

One of the cassava processing businesses that are mostly carried out by the community in Agam Regency, especially in Kamang Magek District is making cassava crackers or better known as Kerupuk Kamang. This cassava crackers business is usually managed by the Home Industry or Small and Medium Industry groups. The marketing process currently carried out is by selling the production of cassava crackers to traditional markets and local distributors, besides that the cassava crackers sold are still in the form of kilos and do not have attractive packaging so that the selling price of cassava crackers is lower. This has an impact on the profits obtained by MSME in the Kamang Magek District, Agam Regency to be small. So that in order to get more profit or income, these MSME must be able to develop marketing and packaging of their products so that more markets can be reached. For this reason, it is necessary to provide briefing/counseling on how to carry out a good marketing strategy, in addition to providing knowledge related to the packaging process that can attract the attention of consumers. As a result of this activity, the community gained new insights regarding good marketing strategies to increase revenue and attract customers, such as making products of various flavors, using product labels/product brands, attractive packaging, promotions with social media and P-IRT permits.

Abstract

The rapid development of the palm oil industry, which cannot be denied, has an impact on the amount of industrial waste, particularly wastewater, requiring proper and effective treatment to reduce the impact of the damage. Wastewater treatment of Palm Oil Mill Effluent (POME) in an aerobic pond requires an adequate supply of oxygen so that its quality improves and becomes disposable, so it requires assistance from aeration media. A fine bubble diffuser was used as the aeration medium in this study. The aeration medium in this study was a fine bubble diffuser. The purpose of this research is to investigate the impact of installing a diffuser on the quality of the final wastewater, particularly the COD and BOD values, in the palm oil industry wastewater treatment. The analysis results for the wastewater parameters after the installation of the fine bubble diffuser revealed a significant reduction in the waste's COD and BOD values to 130 – 175 mg/L and 67 – 78 mg/L, respectively, making it more suitable for disposal to the environment.
