Abstract

Beberapa masalah dalam bidang pertanian di Indonesia berdampak negatif terhadap indeks ketahanan pangan. Sistem akuaponik dapat mengatasi hal tersebut karena sistem ini menghasilkan ikan dan tanaman dengan ramah lingkungan sehingga memungkinkan proses instalasi yang mudah. Desa Grenden yang terletak di Kecamatan Puger, Kabupaten Jember, sebagian wilayahnya masih tergolong lahan sawah produktif namun minat pemuda bekerja di bidang pertanian kurang. Permasalahan lain yaitu pabrik sedang melakukan pengurangan tenaga kerja secara besar-besaran yang menyebabkan banyaknya pemuda yang awalnya sebagai buruh kasar di pabrik menjadi pengangguran. Hal ini yang mendasari tim pengabdian dari Program Studi Teknik Kimia Universitas Jember untuk melakukan sosialisasi mengenai penerapan sistem akuaponik. Berdasarkan hasil diskusi dengan mitra terkait permasalahan yang dihadapi, kegiatan ini menggunakan metode sosialisasi dan pendampingan dalam menerapkan integrated farming berbasis zero waste yaitu dengan konsep pertanian akuaponik. Metode kegiatan yang dilakukan, yaitu memberikan sosialisai mengenai penerapan pertanian terpadu dengan sistem akuaponik. Sosialisasi dilakukan agar karang taruna Desa Grenden mampu menciptakan peluang usaha yang dapat diterapkan. Hasil sosialisasi menunjukkan bahwa masyarakat Desa Grenden memahami konsep mampu menerapkan sistem akuaponik.

Abstract

In this research, the extraction of essential oil from fresh basil leaves using solvent-free microwave extraction (SFME)and microwave hydrodistillation (MHD) method. Several parameters influence the extraction of basil oil using SFME method: microwave power, the ratio between the mass of raw material with a volume of distiller (F/D), material size, and length of extraction time. Besides, the components contained in basil oil and changes in oil gland conditions in basil leaves before and after being extracted were also evaluated. The optimum condition was obtained as follows: microwave power of 380 W, the ratio between the mass of raw material with a volume of distiller (F/D) of 0.1 g/mL, raw material size of intact (± 3 cm), with an extraction time of 60 min. Moreover, SFME has a shorter extraction time to produce yields than MHD methods. GC-MS analyzed the composition of basil oil, and there were 49 identified components. This study shows that SFME method more effective than the MHD method for extraction basil oil from fresh leaves based on time extraction and yield.

Abstract

Indonesia is one of the producing countries essential oils, essential oils are also a commodity that can generate foreign exchange for the country. Therefore, essential oils receive special attention from the Indonesian government. Indonesia generate 40-50 types of plants that produce essential oils and are traded in the world. Extraction using a microwave with the basic mechanism of microwave heating involves stirring polar molecules or ions that oscillate due to the influence of electric and magnetic fields called dipolar polarization. From the results of physical analysis, it can be seen that citronella essential oil obtained using the Solvent Free Microwave Extraction (SFME) method has met the standards and quality of citronella oil based on SNI 06-3953-1995, according to the parameters of color, specific gravity, and solubility in water. 80% ethanol shows citronella oil with good quality. The results of GC-MS (Gas Chromatography-Mass Spectrometry) analysis on the extraction of citronella essential oil using the Solvent Free Microwave Extraction (SFME) method obtained 2 components, namely citronella and geraniol, with citronellal percentages of 8.64% and 7.53%. Optimal operating conditions for the extraction of essential oils from citronella raw materials using the Solvent Free Microwave Extraction (SFME) method.

Abstract

The challenges faced by the Indonesian state are increasing greenhouse gases, climate change, and depleting fossil fuel reserves. This requires the exploration of alternative energy that is environmentally friendly and sustainable. Algae biomass, especially Ulva sp. is one of the resources that have the potential for bioethanol production as an alternative energy producer. The purpose of this study is to determine the potential of Ulva sp. as raw material for bioethanol and to determine the effect of particle size, solvent concentration, and power on the hydrolysis process. This study used Ulva sp. as raw material. hydrolyzed with HCl solvent using the microwave assisted hydrolysis method. Hydrolysis with HCl concentrations of 0.1 N, 1 N, 2 N, variations of microwave power 150 watts, 300 watts, 450 watts, and particle sizes of 60 mesh, 80 mesh, and 100 mesh. Measurement of reducing sugar levels was carried out using the dinitro salicylic acid (DNS) method. The results showed that the best conditions for hydrolysis were when the HCl concentration was 0.1 N, the microwave power was 450 watts, and the particle size was 80 mesh which resulted in a reducing sugar content of 20.751 mg/mL.

Abstract

Labu siam (Sechium edule) merupakan tumbuhan dari famili Cucurbitaceae mengandung beberapa vitamin, seperti vitamin A, B dan C sehingga seringkali digunakan untuk mengobati penyakit. Berdasarkan analisis fitokimia ekstrak labu siam menunjukkan adanya senyawa bioaktif berupa fenolik. Senyawa fenolik merupakan metabolit sekunder dan dimanfaatkan sebagai bahan kosmetik dan obat-obatan karena mengurangi stress oksidatif. Penelitian ini bertujuan untuk mengetahui kandungan total fenolik dan aktivitas antioksidan ekstrak labu siam (Sechium edule) dengan metode spektrofotometri UV-Vis. Ekstrak labu siam diperoleh dengan metode Ultrasonic Assisted-Extraction (UAE) dengan pelarut etanol 96%. Variabel ekstraksi yang digunakan adalah waktu (15, 20, dan 25 menit), amplitudo (45, 65, dan 85 %), serta rasio pelarut (1:5, 1:10, dan 1:15). Penentuan kandungan total fenolik didasarkan pada metode Folin-Ciocalteau serta aktivitas antioksidan menggunakan DPPH. Penentuan parameter ekstraksi labu siam terhadap kandungan total fenolik ditentukan dengan metode Response Surface Methodology dengan tipe Box-Behnken. Kondisi optimal yang diperoleh untuk ekstraksi labu siam sebesar 1,327 mg GAE/gr sampel dan aktivitas antioksidan sebesar 29,45% pada kondisi waktu 20 menit, amplitudo 65%, dan rasio pelarut 1:10.

Abstract

The practical technique for membrane modification is dip coating. This study coats a PVDF hollow fiber membrane-based composite with a coating of zeolite. The composite is made of a polyvinylidene fluoride (PVDF) membrane. During water filtering, the separation capabilities and propensities of composite membranes for organic impurities were examined. Fourier-transform infrared spectroscopy analysis of the findings demonstrated that the Zeolite coating was successfully deposited on the PVDF membrane. The flux recovery ratio increases from 69% to 80% while the relative flux drop decreases from 63% to 50%. A composite PVDF membrane dip-coating of Zeolite with a GA and H2SO4 ratio of 1:2 is needed to remove about 75% of humic compounds from effluent. The results of this study show that the addition of Zeolite with a GA and H2SO4 layer can greatly improve the hydrophilicity, selectivity, and anti-organic fouling of the PVDF hollow fiber membrane.

Abstract

Turmeric leaves (Curcuma longa L.) contain phytochemical compounds that can be utilized as natural food preservatives or bioformalin due to its antibacterial properties. The extraction method used in this study is Ultrasound-Assisted Extraction (UAE), with the aim to determine the effect of variable sample-solvent ratio, time, and particle size on total flavonoid, tannin, and alkaloid compounds, as well as to determine the optimal shelf life of fresh tuna. This study used sample-solvent ratio variables of 1:10, 1:15, and 1:20; time variables of 10, 20, and 30 minutes; and particle size variables of 60, 80, and 100 mesh. The highest total flavonoid compound was obtained in the variable sample-solvent ratio of 1:20, particle size of 100 mesh, and time of 20 minutes at 98,076 mg/L. The highest total tannin compound was obtained in the variable sample-solvent ratio of 1:15, particle size of 60 mesh, and time of 10 minutes at 41,697 mg/L. The highest total alkaloid compound was obtained in the variable sample-solvent ratio of 1:10, particle size of 100 mesh, and time of 20 minutes at 10,092 mg/L. The optimum curing time for tuna is 36 hours at room temperature with variable sample-solvent ratio, time, and particle size of 1:20 g/mL, 20 minutes, and 100 mesh with 20% concentration. The running has the highest flavonoid compounds, so it can be concluded that flavonoid compounds have a major effect on the preservation process of tuna.
