Oily scum was treated by hydrothermal dewatering (HTD) under 120-240°C. The changes of surface characteristics and physico-chemical structure of oily scum were investigated and the effect of temperature on the properties of the hydro-char obtained from oily scum was analyzed through different characterization techniques. Results show that the moisture content of HTD treated hydro-char decreases as the temperature increases, which implies that the oily scum can be dewatered and upgraded through HTD method. The morphologies of the HTD pretreated oily scum present less oil content, smaller particle size, and become darker. As the reactor temperature increases from 120 to 240°C during the HTD process, the moisture content of hydro-char obtained decreases from 35.51 to 11.31%, while the liquid content and hydro-char content increase from 58.53 to 79.76% and from 2.50 to 5.29%, respectively, and the released gas content slightly varies in the range of 3.14 - 4.31%. The breaking and gathering effects of the HTD upgrading on oily scum result in a wide particle size distribution of products, which indicates that the overall structure of raw oily scum has been destroyed. With the increase of HTD temperature, the shorten vibration of methylene groups in hydro-char products is weakened.

Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan menthol sebagai bahan konsolidasi sementara cagar budaya pada temuan ekskavasi yang rapuh. Pengujian yang dilakukan meliputi karakteristik morfologi menthol, penetrasi kering dan basah menthol pada ketiga jenis sampel (Arang, Bata, Batu), durabilitas konsolidasi sementara menthol pada sampel, dan kuat tekan. Hasil penelitian menunjukkan bahwa proses solidifikasi menthol dimulai pada bagian tepi dan membentuk bentukan seperti jarum (whisker). Penetrasi menthol pada sampel sangat dipengaruhi oleh bentuk dan ukuran partikel sampel serta kandungan air yang terdapat pada sampel. Untuk pengujian durabilitas, pengaruh suhu sangat besar terhadap durabilitas konsolidasi menthol. Semakin tinggi suhu lingkungan, maka semakin cepat pula proses sublimasi menthol. Hasil uji kuat tekan sangat dipengaruhi oleh ukuran partikel sampel, semakin kecil ukuran partikel sampel yang terkonsolidasi menthol, maka semakin tinggi pula nilai kuat tekan yang dihasilkan. Dari hasil penelitian ini dapat disimpulkan bahwa menthol dapat digunakan sebagai bahan konsolidan sementara cagar budaya arang. This study aims to determine the effectiveness of the use of menthol as temporary consolidant for fragile heritage findings on the excavation site. Test includes morphological characteristic of menthol, dray and wet penetration of menthol to three type of sample (charcoal, stone, and brick), durability, and compressive strength. The results show that the menthol solidification process starts at the edges and forms a shape like whiskers. Menthol penetration is strongly influenced by the shape and size of the sample and also water content in the samples. For durability testing, the effect of temperature is very significant on the durability of menthol consolidation. The higher the temperature, the faster the menthol sublimation process will be. Whereas for compressive strength is highly influenced by particle size of the consolidated sample, the smaller consolidated sample the higher compressive strength produced. From this study it can be concluded that menthol can be used as a temporary consolidant material for the fragile heritage findings.

The Way

Palm plantation  produce waste in form of palm midribs in large number. One of the way to handle and increase the value of palm midrib waste is by pyrolysis. The particle size of raw material that used in this study was 23 – 50 mesh. The reduction of raw material size can increase the heating rate of pyrolysis. This study aimed to analyze the effect of temperature, time, and water content of raw material on the yield and pH of liquid smoke. Pyrolysis of palm midrib powder was processed at 150 oC, 200 oC, and 250 oC  with various time was 30 minutes, 60 minutes, and 90 minutes. The study found that the yield of liquid smoke tend to increase with rising pyrolysis temperature and time until the condition when un-condensable gas was produced more so that the increase of pyrolysis temperature and time will further decrease the yield. The highest yield of liquid smoke obtained at 250 oC for 30 minutes, is 20,69%. The best pH of liquid smoke obtained at pyrolysis temperature 250 oC for 90 minutes, is 2,6.
