Abstract

Kefir milk is one of the fermented products of milk which contains lactic acid bacteria and yeast. Kefir milk is a functional and probiotics drink. Giripurno Village is one of the suppliers of pure cow's milk in the KUD in Batu City. Milk which produced by the residents of Giripurno Village is still not being utilized optimally, because milk marketing only depends on cooperatives. The main objective of community service activities is to maximize the utilization of milk through training related to milk processing, especially for making kefir milk. The community service method includes several stages, such as the discussion stage and field observation, the preparation stage, and the training stage. The results of the activity are increasing knowledge of the Giripurno Village community, especially the Dasa Wisma women's group about kefir milk products and increasing skills for making kefir milk products. The conclusion that can be given from this community service is the group of women feel educated and helped in finding ideas for processing cow's milk. The recommendations are required for an innovation to improve the taste of kefir milk and assistance in product manufacturing.

Abstract

The Lawson dye contained in the leaves of Lawsonia inermis L. has a red-orange color, which can be used as a fabric dye. The solvent is ethanol because it can attract flavonoid compounds bound to Lawson. The ultrasonic-assisted extraction method is employed to enhance the extraction process by breaking down cell walls, thereby facilitating a more rapid extraction of the desired solute. This study investigated the effects of material-to-solvent ratio, ethanol concentration, and extraction time. The research results were analyzed using a UV-Visible spectrophotometer to determine the yield of Lawson extract. The Face-Centered Composite Design (FCCCD) method was applied to this study to obtain optimal analysis results and extraction conditions. The independent variables in this study were the ratio of ingredients to solvent (0.02-0.06 g/g), ethanol concentration (20-60%), and extraction time (5-15 minutes). The optimal extraction conditions were obtained at a ratio of 0.02 g/g, an ethanol concentration of 60%, and an extraction time of 15 minutes, with a predicted model yield of 15.417%. The actual yield under these conditions was found to be 15.4934%. Furthermore, the extraction kinetics model was analyzed to study and predict the optimal Lawson extraction results. Extraction kinetics calculations were carried out using first-order and second-order based on the Lagergren equation. The most suitable extraction kinetic model is second-order with a determinant coefficient value, or the value of R2 is 1, which indicates that the order kinetic model equation represents the actual conditions.

Abstract

The kinetic reaction of alkaline hydrolysis of candlenut shells to produce oxalic acid was investigated. It was performed for the non-catalyzed solid-liquid heterogeneous reaction in a range time of 30 to 90 minutes and temperature of 60oC to 90oC. This study showed that the reaction fitted the pseudo-first-order model, confirmed from the determinant coefficient value of 0.9182 to 0.9751, and the kinetic constant, evaluated using Arrhenius' law, was k= 0.034751 e^(-140.23⁄T). The rate control mechanism based on the shrinking core model was diffusion control, validated from determinant coefficient near one, from 0.9246 to 0.9766.

Abstract

The government has taken energy deflation seriously and is trying to find solutions by implementing energy efficiency and utilizing renewable energy sources. That action also supports the procedure to save the world from the ongoing climate crisis. One of Indonesia’s potential renewable energy sources is biomass, which can be in the form of plantation waste such as teak branches. Based on the analysis results, charcoal made from teak branches had a carbon content about 62.5968%, so it was pretty potential to be used as raw material for bio-briquettes. In this research, bio-briquette from teak branches' charcoal using tapioca binder has been successfully carried out. The manufacture of bio-briquettes was studied by observing the effect of the size parameters of teak charcoal and binder ratio on the heating value and water content of briquettes. The analysis results showed that these two parameters significantly affected the quality of teak branches' bio-briquette. In the ranking, the particle size was much more significant in influencing the calorific value of bio-briquettes, while the binder ratio had more influence on the water content value. The obtained bio-briquettes' calorific value and water content have met the established standards.

Abstract

Karbon aktif merupakan salah satu adsorben yang paling sering digunakan. Salah satu senyawa yang dapat diserap yaitu asam asetat. Untuk mengetahui kinerja adsoben lebih lanjut, maka diperlukan studi kinetika berdasarkan persamaan isotherm Freundlich. Isoterm Freundlich mampu menunjukkan jenis adsopsi apakah secara kimisorpsi atau fisisorpsi dan berlangsung secara multilayer. Studi kinetika pseudo first orde dan pseudo second orde dimaksudkan untuk mengetahui mekanisme dan karakteristik adsorpsi yang berlangsung. Penelitian ini bertujuan untuk mengetahui konstanta isotherm Freundlich dan kinetika adsorpsi karbon aktif terhadap asam asetat. Konsentrasi asam asetat yang digunakan untuk mengetahui konstanta freundlich yaitu 0,5M, 0,25M, 0,125M, 0,0625M, 0,03125M dengan lama waktu kontak selama 10 menit. Sedangkan kinetika adsorpsi dilakukan dengan menggunakan asam asetat yang berkonsentrasi 0,5 M dengan waktu adsorpsi 2 menit, 4 menit, 6 menit, 8 menit dan 10 menit. Kemudian filtrat di titrasi dengan NaOH 0,1N. Ukuran karbon aktif yang digunakan antara lain 180 mess, 420 mess dan 600 mess.  Data yang diperoleh dianalisis dengan persamaan freundlich, pseudo first orde dan pseudo second orde. Data analisis yang didapatkan nilai konstanta freundlich yaitu sebesar 50,00342 dan memenuhi kinetika orde dua yang artinya, proses adsorpsi dipengaruhi lebih dari satu faktor.

Abstract

Pengambilan minyak atsiri serai wangi dapat dilakukan dengan berbagai jenis metode ekstraksi. Metode ekstraksi yang digunakan dapat mempengaruhi kuantitas produk minyak atsiri yang didapatkan. Metode ekstraksi nonkonvensional memberikan efisiensi dan efektivitas yang baik. Salah satu metode ekstraksi nonkonvensional adalah Microwave Assisted Extraction (MAE). Metode MAE memiliki banyak pengembangan seperti Microwave Steam Distillation (MSD) dan Microwave Steam Diffusion (MSDf). Pada penelitian ini, metode MSD dan MSDf dikaji dengan membandingkan hasil ekstraksi minyak serai wangi yang diperoleh dengan metode MSD dan MSDf yang menerapkan teknik ekstraksi Chouhan. Hasil penelitian menunjukkan bahwa yield minyak serai wangi yang diekstrak dengan metode MSD lebih tinggi dibandingkan yield hasil ekstraksi dengan metode MSDf baik itu pada metode dengan atau tanpa penerapan teknik ekstraksi Chouhan, dimana yield tertinggi diperoleh pada metode MSD kombinasi penggunaan teknik Chouhan dengan nilai sebesar 3,2% (b/b). Analisis indeks bias dan warna produk minyak serai wangi yang diperoleh pada metode MSD dan MSDf dengan atau tanpa penerapan teknik Chouhan secara garis besar telah memenuhi SNI. Adapun hasil pengujian Gas Chromatography Mass Spectrometry (GCMS) menunjukkan bahwa komponen utama dalam minyak serai wangi hasil ekstraksi dengan metode MSD dan MSDf adalah sama yaitu geraniol dengan persentase pada masing-masing metode secara berurutan adalah 48,52% dan 46,82%.

Abstract

Leaves of citronella (Cymbopogon nardus L.) have pretty much essential oil. Essential oil from citronella leaves is generally extracted by conventional methods. Conventional method is still less effective. The problem can be overcome by using non-conventional methods in the form of UMAE (Ultrasound-Microwave Assisted Extraction). UMAE is an extraction process assisted by ultrasound and microwaves. NaCl solution can be used as a solvent in the UMAE method because NaCl has a large dielectric constant. The aim of this study was to examine the effect of extraction time and the addition of salt on the yield and color of essential oils produced using the UMAE. The extraction process begins with the raw material preparation stage, such as harvesting, size reduction, and drying. Then, pre-treatment was carried out using ultrasound for 5 minutes at 35oC with the addition of 2, 4, 6, 8, and 10% (w/v) salt. Pre-treatment results were followed by the extraction process using microwaves for 30, 45, 60, 75, and 90 minutes. The best results were obtained with the addition of 6% salt and 60 minutes of extraction time with a feed to solvent ratio of 0.1 with a yield of 1.975%. and the color is yellow.
