The reaction kinetics and the effect of power on microwave-assisted pyrolysis (MAP) in converting microalgae to biofuel were investigated to determine the decomposition mechanism and then characterize the best product. The resulting product consisted of three phases, namely liquid phase (bio-oil), solid residue (char), and uncondensable gas products. The results showed that the optimal increase in microwave power obtained was 20.57% with a 600-watt microwave power condition, a reaction time of 20 minutes, a microwave absorber to microalgae ratio of 1:6, and a heating rate of 25.96 K/min (600 watts). The reaction kinetics evaluated in the best condition showed a second-order reaction with activition energy (Ea) and pre-exponential factor (A) at 35.5971 kJ/moles and 2,606.75/minute, respectively. The characteristics of the biofuel product obtained were 1.01 gr/mL density, viscosity 10.97 cP, and pH 9.30. In addition, based on GC-MS analysis, the bio-oil contained aliphatic, aromatic, phenol, FAME, and polycyclic aromatic hydrocarbon (PAH) organic compounds. These results indicate that MAP has the potential to be developed as an alternative production process for biofuels.

In this study, the oil extraction of Calophyllum inophyllum L using microwave hydro-diffusion gravity method and chemical extraction method were elaborated. The Microwave Hydrodiffusion Gravity (MHG) method is a new green technique which combines microwave-assisted technology and gravitation. It is used to produce oil yield faster and at a low cost. In comparison, a chemical extraction method is a conventional method. The raw material pretreatment, extraction time, microwave power, and the material size have become a crucial factor of extraction. In general, the MHG method yields a higher yield than the chemical extraction method. The MHG method is simple and less solvent. It requires faster extraction time and produces higher oil yield.

Microalgae, as a potential raw material for biofuel, has several advantages compared to other biomass. One effective way to convert microalgae into biofuel is by thermal cracking or pyrolysis, and using a catalyst or not. So far, studies on the use of microalgae, that are converted into biofuels, is still use highly concentrated catalysts in packed bed reactors, which is not economical. Therefore, the aim of this study is to convert Chlorella sp. into biofuels with conventional pyrolysis without and using an activated carbon catalyst using packed bed reactor with bubble column. The reaction temperature is 400–600 °C, pyrolysis time is 1–4 hours, and the active carbon catalyst concentration is 0–2%. The 200 grams of Chlorella sp. and the catalyst was mixed in a fixed bed reactor under vacuum (−3 mm H20) condition. Next, we set the reaction temperature. When the temperature was reached, the pyrolysis was begun. After certain time was reached, the pyrolysis produced a liquid oil product. Oil products are measured for density and viscosity. The results showed that the conventional pyrolysis succeeded in converting microalgae Chlorella sp. into liquid biofuels. The highest yield of total liquid oil is obtained 50.2 % (heavy fraction yield, 43.75% and light fraction yield, 6.44%) at the highest conditions which was obtained with 1% activated carbon at a temperature and pyrolysis time of 3 hours. Physical properties of liquid biofuel are density of 0.88 kg/m3 and viscosity of 5.79 cSt. This physical properties are within the range of the national biodiesel standard SNI 7182-2012. The packed bed reactor completed with bubble column is the best choice for converting biofuel from microalgae, because it gives different fractions, so that it is easier to process further to the commercial biofuel stage.

Limbah merupakan sisa hasil dari sebuah proses atau usaha yang tidak dapat digunakan kembali serta memberikan efek negative terhadap lingkungan. Dalam keseharian, UMKM Jenang Murni di Ponorogo, menghasilkan limbah air kelapa sebanyak 30–40 liter dan limbah cair tersebut hanya hanya dibuang ke lingkungan. Hal ini, tentu akan menyebabkan permasalahan lingkungan. Di sisi lain, kebutuhan dan harga pupuk yang semakin meningkat dan mahal, dan sebagai upaya untuk mencegah kerusakan tanah akibat penggunaan pupuk anorganik. Tuntutan untuk mengurangi pencemaran lingkungan dan merespon kebutuhan serta mahalnya harga pupuk, melatarbelakangi pengabdian tentang pemanfaatan limbah menjadi lebih bermanfaat dan bernilai ekonomis. Permasalahan tersebut, dapat diatasi dengan mengolah limbah air kelapa menjadi pupuk organik cair.

Seiring dengan meningkatnya kebutuhan akan bahan makanan yang tidak mudah rusak, boraks banyak sekali digunakan dalam industri makanan, seperti: dalam pembuatan mie basah, lontong, ketupat, tahu, bakso, sosis, dan lain-lain. Selain boraks, formalin juga banyak digunakan sebagai bahan pengawet makanan. Padahal zat-zat kimia tersebut merupakan bahan beracun dan bahan berbahaya bagi manusia sehingga sangat dilarang digunakan sebagai bahan baku makanan. Oleh karena itu, diperlukan metode identifikasi yang sederhana (simple method) untuk kedua bahan berbahaya tersebut dalam makanan. Sehingga, dapat dilakukan oleh konsumen terutama para ibu rumah tangga dengan mudah. Untuk menguji validitas dari simple method tersebut, maka hasil ujinya perlu dibandingkan dengan scientific method. Hasil uji kandungan boraks pada makanan dengan menggunakan simple method telah dilakukan di Laboratorium dan hasil uji menunjukaan bahwa dari 28 sampel yang di uji, ada dua sample yang positif mengandung boraks. Hasil dari metode nyala api yang merupakan scientific method untuk uji kandungan boraks menunjukkan hasil yang sama dengan hasil uji menggunakan simple method. Sedangkan pada uji formalin, baik menggunakan scientific method menunjukkan hasil bahwa terdapat tujuh sampel yang positif mengandung formalin dari 28 sampel yang diuji dan sebagian besar sampel tersebut merupakan ikan asin. Hasil dari uji tersebut telah disosialisasikan kepada masyarakat sekitar Institut Teknologi Sepuluh Nopember (ITS), yaitu ibu-ibu PKK di Perumahan Sukolilo Dian Regency RT 8 dan 9, RW 2 Kelurahan Keputih Kecamatan Sukolilo Surabaya pada 26 Juni 2016 dan dilakukan sosialisasi kedua pada tanggal 30 Juli 2016 untuk melihat tingkat keberhasilan dan keberlanjutan dari sosialisasi yang pertama.
