Abstract

The acquisition of subsidized diesel fuel is challenging, and the elevated prices of non-subsidized diesel fuel have significantly impacted small and medium enterprise groups, causing operational issues. To mitigate this problem, it is vital to explore alternative fuels that can replace diesel fuel. Used cooking oil presents itself as a viable substitute for diesel fuel due to the abundance of cooking oil in households, which has the potential to cause environmental pollution. The esterification reaction can be employed to convert used cooking oil into biodiesel, suitable for use in diesel engines. This training aims to provide comprehensive guidance and practical training to Kharisma household business members on the production of biodiesel from used cooking oil. The training methods encompass lectures, discussions, and demonstrations. The reactor utilized has a 30-liter capacity for used cooking oil. The training results indicate that the Kharisma household business members are proficient in operating the biodiesel-making equipment (reactors) and are capable of independently producing biodiesel.

Abstract

The quality of Red Fruit Oil (RFO) is influenced by the extraction method. The objective of this research was to study the effect of temperature and heating time of red fruit on the chemical quality of red fruit oil using the dry extraction method. This research was divided into two steps: 1) evaluation of the chemical quality (water content, free fatty acid (FFA), iodine value, and carotenoid total) of the red fruit oil during the steaming of red fruit grains (drupa) at 60 , 80 , and 100°C  for 20, 80, and 60 minutes; and 2) evaluation of the chemical quality (water content, FFA, and total carotenoids) of RFO during the steaming of red fruit chunk of whole fruit (cepallum) at 100°C for 60 minutes and 120°C for 30 minutes. The results showed that increasing the temperature and heating time of red fruit grains increased the yield (1.20 to 5.95%) and decreased the FFA levels (4.5 to 2.7%); however, the total carotenoid content of oil tended to decrease (from 7570 to 7209 μg/mL). Heating at 100°C for 60 minutes did not affect the level of saturated fatty acids in RFO. The steaming process of the red fruit chunk of whole fruit before extraction could decrease the oil yield and total carotenoid levels, as well as lower the FFA level of oil than steaming of red fruit grains.

Abstract

Kontaminasi mikroba pada rempah dapat disebabkan oleh faktor lingkungan seperti suhu, kelembaban, kondisi sebelum dan pasca panen, serta kondisi tempat penyimpanan rempah tersebut. Tujuan dari penelitian ini adalah mengetahui tingkat sanitasi dan higiene pedagang rempah (kunyit, lada dan pala), menentukan total cemaran mikroba kontaminan, dan menentukan faktor intrinsik dan ekstrinsik yang dapat mempengaruhi cemaran mikroba pada rempah. Penelitian ini menggunakan metode survey yang dilakukan pada 2 pasar tradisional di kota Manokwari. Analisis data diolah menggunakan PCA (Principal Component Analysis). Hasil penelitian menunjukkan bahwa tingkat sanitasi dan higiene pedagang rempah di pasar tradisional kota Manokwari berada pada kategori kurang sampai cukup dengan persentase skor PSAT (Pangan Segar Asal Tumbuhan) 44-71% pada pasar Sanggeng, dan 44-65% untuk pasar Wosi. Pedagang di pasar Sanggeng dan Wosi dengan sanitasi tertinggi dikodekan sebagai ST dan WT sedangkan pedagang dengan sanitasi terrendah dikodekan sebagai SR dan WR. Rata-rata Angka Lempeng Total dan Angka Kapang Khamir untuk sampel kunyit dan pala dari pedagang ST, kunyit, lada, dan pala dari pedagang SR, lada dan pala dari pedagang WT dan WR, masih di bawah batas maksimum dari standar yang telah ditetapkan SNI 01-3709-1995. Sedangkan sampel lada dari pedagang ST dan kunyit dari pedagang WT dan WR, memiliki total bakteri TBUD (terlalu banyak untuk dihitung), artinya sudah melewati batas maksimum standar SNI 01-3709-1995 yaitu maksimal 106 CFU/g. Faktor intrinsik yang dapat mempengaruhi cemaran mikroba pada rempah adalah nilai aktivitas air dan kadar air, sedangkan faktor ekstrinsik yang dapat mempengaruhi cemaran mikroba adalah kelembaban relatif dan suhu lingkungan di pasar.

Abstract

Background: Water and nutrient limitations in karst soils hinder the optimal growth of shallots, so water and nutrient management is carried out using variations in micro-irrigation and NPK fertilization. Variations in micro-irrigation and NPK fertilization can support the growth and flavonoid content of shallots.Aims: This study aims to analyze nutrient uptake and total flavonoid production of shallots in karst soils with variations in micro-irrigation and NPK fertilization.Methods: The research used a Randomized Block Design (RBD) containing two main factors. The first factor was the irrigation technique, consisting drip irrigation (I1) and mist irrigation (I2). The second factor was the NPK fertilizer dosage, consisting three levels: 0 kg/ha (N1), 500 kg/ha (N2), and 1000 kg/ha (N3). The parameters observed included soil moisture, soil NPK availability, plant NPK uptake, total flavonoids, growth, and shallot yield.Results: The results showed that mist irrigation with an NPK dose of 1000 kg/ha yielded higher results compared to drip irrigation in terms of soil moisture, NPK availability and uptake, growth, and yield. The highest availability of nitrogen, phosphorus, and potassium in mist irrigation with a dose of 1000 kg/ha was 0.36%, 89.20 ppm, and 0.66 me%, respectively. Phosphorus uptake in mist irrigation was higher than in drip irrigation, at 0.81% and 0.89%, respectively. Growth and yield under mist irrigation with an NPK dose of 1000 kg/ha also yielded the best results compared to drip irrigation with an NPK dose of 1000 kg/ha, namely plant height (30.69 and 29.74 cm), number of leaves (27.65 and 25.77 leaves), and bulb diameter (30.07 and 27.02 mm). The highest total flavonoid content was observed in drip irrigation with a 500 kg/ha dose compared to mist irrigation with a 500 kg/ha dose, namely (78.83 and 50.96 mg/kg). Overall, irrigation techniques with varying NPK doses were able to increase nutrient and flavonoid uptake in shallot on karst land.
