Abstract

Minyak nilam dan serai wangi merupakan minyak atsiri utama Indonesia dan penyumbang tertinggi minyak atsiri dunia. Minyak atsiri terdiri dari komponen kimia, yaitu komponen ringan, sedang, dan berat. Penelitian ini bertujuan untuk mendapatkan fraksi dan menentukan komposisi kimia serta aktivitas antioksidannya. Alat destilasi spinning band destillation digunakan untuk fraksinasi minyak mentah pada suhu dan tekanan tertentu. Komposisi kimia ditentukan menggunakan GC-MS dan antioksidan ditentukan dengan metode DPPH. Kromatogram GC-MS mendeteksi 20 komponen  dalam fraksi minyak nilam dan 35 komponen dalam fraksi minyak serai wangi. Komponen utama fraksi-1 pada minyak nilam adalah α dan β pinene, fraksi-2 adalah β-patchoulene dan α-quaiene, fraksi 3 adalah α dan δ quaiene, fraksi 4 dan 5 adalah patchouli alcohol. Komponen utama fraksi-1 minyak serai wangi adalah limonene dan citronellal, fraksi-2 dan 3 adalah citronellal, dan geraniol dalam fraksi-4 dan 5. Aktivitas antioksidan fraksi minyak nilam tidak berbeda nyata, sedangkan aktivitas antioksidan fraksi-5 minyak serai wangi signifikan lebih tinggi dibandingkan fraksi lainnya. Komponen geraniol dan cardinene dengan gugus phenolnya berkontribusi terhadap aktivitas antioksidan.

Abstract

Penelitian pembuatan mi jagung kering untuk diversifikasi produk non gandum telah dilakukan. Penelitian ini bertujuan untuk mengkaji perubahan mutu (organoleptik, kimia dan mikrobiologis) pada produk mi jagung selama penyimpanan dan mendapatkan pendugaan umur simpan produk mi jagung dengan metode Arrhenius. Produk disimpan pada suhu 8oC, 28oC, 38oC, dan 48oC selama 8 minggu dan diamati perubahan mutunya. Parameter mutu yang diamati adalah kadar FFA, kadar air, total mikroba, warna, rasa, dan aroma tengik. Umur simpan diduga menggunakan metode Arrhenius. Hasil penelitian menunjukkan mi jagung kering mengalami penurunan mutu selama 8 minggu yang ditandai dengan meningkatnya asam lemak bebas dan aroma tengik serta menurunnya warna dan rasa. Tetapi mi jagung kering relatif stabil selama penyimpanan berdasarkan parameter  kadar air dan total mikroba. Pada suhu penyimpanan 28oC berdasarkan parameter kritis sensoris rasa. (nilai  Ea = 593,75 kal/mol), yaitu 10,66 minggu. Suhu penyimpanan untuk mi jagung kering yang direkomendasikan adalah 28oC – 38oC.

Abstract

Lead heavy metal (Pb) contamination increases along with the community-managed waste processing of used lead batteries. People living in the vicinity of the lead smelter are at risk of exposure to lead which can have an impact on health. This study aims to identify the level of lead in the environment around post-closure used battery melting. The research used a quantitative descriptive method approach. Data collection was carried out by interview and sampling test. The test sample was taken purposive at two smelting locations, namely Cinangka Village and Jagabaya Village in Bogor Regency, Indonesia. The results showed that there was still lead exposure in the soil and in the plants around the smelting site. The high lead levels that have been found require measurable remediation action. This is to minimize the risks that can be caused to humans who are active around the used battery smelting site. In addition to having a negative impact in the form of lead exposure, lead smelting also provides economic benefits for workers in a smelter. Involving workers in collecting or sorting used batteries is an alternative after closing the smelting site. Meanwhile, smelting activities are only carried out by authorized smelters.

Abstract

This study compared the oil yield and identified the quality of cassiavera with plants ages 7 years, 18 years, and random (broken) one. Parameters measured included yield, physicochemical properties, and chemical composition. Based on the results, the oil yield was 1%, 0.9%, and 0.7% at ages 8 and 7 years of upper and lower stem parts, as well as for the broken form. This indicates that the longer plant age correlates with a higher yield. The yield at 7 and 18 years is not much different, hence the harvest can be performed at the age of 7 years considering a shorter waiting period. The physicochemical test of oil solubility in 70% ethanol showed a ratio of 1:1 and a clear appearance according to the maximum requirements of INS (Indonesian National Standard) 06-3734:2006, namely 1:3 clear. Meanwhile, the refractive index (RI) test indicated 1.56 as the best value for cassiavera scion at the age of 7 years in line with INS 06-3734:2006 conditions of 1.559 - 1.595. The chemical composition test for the oil as a whole complied with the minimum standard of INS 06-3734:2006, namely 50% cinnamaldehyde.

Abstract

Siamese orange (Citrus nobilis) is a local citrus that grows in Mount Omeh, Lima Puluh Kota Regency. The quality is improved through thinning which is the process of removing some of the young fruit. Therefore, this research aimed to use young oranges obtained from thinning fruit in the manufacture of essential oils to reduce waste from citrus plants. Orange peel is converted into essential oil through distillation for 6 hours at 90-1000 C. The results showed that the product obtained had a yield of 0.9% (V/V), pale yellow color, volatility with a specific gravity of 0.84%, refractive index of 1.46, 0.67 acid number, solubility in ethanol 1:19 clear, ester number 27, and 0.02 mg/kg Fe content. The socialization of the use of essential oil and hydrosol in soap making to citrus farmers and industrial craftsmen around the Lima Puluh Kota Regency was also performed. The outcome indicate a positive response from the participants and the local government, thereby increasing the commercial value of oranges.

Abstract

Amorphophallus muelleri Blume atau dikenal sebagai porang merupakan sumber pangan tinggi serat yang berasal dari glukomanan yang terdapat pada bagian umbi. Selain pada bagian umbi, glukomanan juga dapat ditemukan pada bagian bulbil (umbi daun) dengan kadar sebesar 25-30%. Produksi bulbil cukup tinggi, sebagian dijadikan bibit, selebihnya dibuang. Oleh karena itu, penelitian ini dilakukan untuk memanfaatkan bulbil sebagai sumber alternatif glukomanan dan optimasi suhu ekstraksi untuk memperoleh glukomanan dengan kadar tinggi. Esktraksi glukomanan dari bulbil menggunakan pelarut etanol teknis 70% dengan perbandingan bobot sampel terhadap pelarut adalah 1:3 (b/v). Bulbil diesktraksi dalam tiga variabel suhu yaitu, suhu 25, 50 dan 75 °C, serta tepung bulbil digunakan sebagai kontrol negatif. Ketiga sampel esktrak dan tepung bulbil diuji kadar glukomanan dan pemeriksaan gugus fungsi menggunakan Fourier Transform-Infra Red (FT-IR). Kadar glukomanan tertinggi didapatkan dari metode ekstraksi menggunakan suhu 75 °C dengan kadar 30,20% (b/b) basis kering. Sedangkan, kadar glukomanan yang diesktraksi pada suhu 25 dan suhu 50 °C secara berturut-turut yaitu 23,07 dan 27,85% (b/b) basis kering. Analisis gugus fungsi menunjukkan sampel bulbil yang diesktraksi memiliki kemiripan spektrum terhadap glukomanan komersial.

Abstract

Beverages and other commodities packaged in bottles for small and medium industries (SMEs) generally require a relatively long production time. This process is significantly dependent on the workers' skills to achieve higher production costs and low efficiency. Therefore, this research designed an automated water-filling device for improving and monitoring SMEs productivity in real-time. The system comprises four types of sensors, namely ultrasonic, temperature, TDS (total dissolved solids), and proximity. The ultrasonic and temperature sensors measure the water level and temperature in the holding tank. The TDS sensor measures the value of substances or particles dissolved in the water, while the proximity sensor detects and counts the number of bottles. Sensor readings are displayed on the LCD (liquid crystal display) and can be monitored via a smartphone using the Blynk application. In conclusion, the existing automation system accompanied by an IoT-based monitoring system can help SMEs to check the quality and efficiency of production in real-time.
