Abstract

Direct extraction and conversion of microalgal lipid to biodiesel in one step process is developed to initiate an efficiently method in the biofuel production. The method that called as in-situ process had been applied in the biodiesel production from microalgae Chlorella vulgaris lipid by involving of sonication assisting. Various parameters that affect the in-situ transesterification were investigated to find the optimum conditions including power of sonication, co-solvent use, and biomass amount. The experiment was performed by acidic catalyst The use of sonication in 25kHz/270W yielded the highest biodiesel product. The apply of co-solvent n-hexane significantly increased the yield biodiesel rather than no co-solvent. The biodiesel yield of 10.39 % obtained when the process was accompanied by the n-hexane.as co-solvent with increasing level as 47% rather than without co-solvent. The in situ process in the ratio biomass - methanol 3:50 that assisted by sonication for 60 mins produced the highest biodiesel, which was 20,31 % w/w. The yield was higher than assisting with reflux or combination of reflux-sonication. The component of biodiesel yielded in the process consisting of 7,10,13-hexadecatrienoic methyl ester; pentadecanoic acid, 14-methyl-methyl ester; 9,12,15-octadecatrienoic acid-methyl ester; and eicosanoic acid-methyl ester. Joining of reflux-sonication exhibited a low biodiesel product. Disadvantage method from the combination may inhibit on lipid extraction or FAME transformation, the exact cause needs to be looked for in the future.

Abstract

In this research, lipolyic bacteria have been isolated from palm oil waste land for the production of lipase. Species of potential lipolytic bacteria were identified based on their morphology and sequences of 16 rRNA gene. Enzymes are produced by growing bacteria in a medium with various vegetable oils and nitrogen sources. The enzyme produced by the bacteria measured its lipolytic activity against the substrate para-nitrophenylpalmitate. The lipolytic bacteria was recognized as Lysinibacillus sphaericus L49a based on morphological and phylogenetic analysis. Mineral media with different vegetable oils as carbon sources, and different nitrogen sources were suitable for growth and production of lipase enzymes of L. sphaericus L49a. Culltivation of L. sphaericus L49a in medium containing ammonium sulfate and olive oil produced lipase with the highest lipolytic activity.

Abstract

Community empowerment and household waste processing are two issues that need to be resolved by the government. An independent and educated society is an important pillar to support the development of country. Meanwhile, waste that continues to accumulate without processing has a negative impact on health and the environment. Public education about household waste processing can be a solution to the two problems above. Education was carried out at Junior High School YBPK Surabaya and residents of Dukuh Kupang Surabaya, and other participants who joined in a hibrid meeting with a total of 116 participants. Activities at YBPK Surabaya took place on 25 March and 5 August 2023 and activities at Dukuh Kupang Surabaya took place on 27 May and 26 August 2023. The types of waste processed are organic waste and used cooking oil, which are then converted into eco-enzymes and used cooking oil Activities are divided into 2 stages. there are community education activities and program sustainability monitoring activities. The community education activities includes presentation and workshop were hold in March 2023 at YBPK Surabaya Middle School and May 2023 at Dukuh Kupang Surabaya. The evaluation of sustainability program including individual practice and monitoring of activities was carried out in August 2023 at Dukuh Kupang Surabaya. Methods for implementing activities include presentation, practice accompanied by a mentor, individual practice, and monitoring program sustainability. Based on the analysis of participants' ability, the participant scores before and after the activity was increase. It means that this training succeeded in increasing participants' knowledge and skills in processing waste, especially organic waste and used cooking oil waste. A total of 72 out of 116 participants (62%) had processed household waste either individually or in groups. Activity evaluation data shows that these activities are necessary and on target to create an independent and creative society.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh fenantren terhadap aktivitas enzim katabolik pada Pseudomonas putida TI (8). Isolat ditumbuhkan pada media Air Mineral Sintetis (AMS) dengan penambahan 1% fenantren. Enzim katabolik diuji aktivitasnya terhadap fenantren. Uji aktivitas enzim ditentukan berdasarkan penurunan absorbansi NADH pada panjang gelombang 340 nm. Satu unit aktivitas enzim dinyatakan sebagai jumlah enzim yang membutuhkan 1 µmol NADH untuk mengoksidasi substrat. Hasil penelitian menunjukkan bahwa isolat dapat tumbuh menggunakan fenantren hingga 10 hari inkubasi. Aktivitas enzim katabolik tertinggi terhadap fenantren pada inkubasi hari ke 8 sebesar 5,391 U/mL. Penambahan 1% hidrokarbon poliaromatik dapat meningkatkan aktivitas enzim sebesar 10 kali, hal ini menunjukkan bahwa enzim katabolik pada Pseudomonas putida TI (8) merupakan enzim induktif.

Abstract

This study examines the effect of fermented lime peel waste flour (FLPWF) on the digestive tract dimensions of broiler chickens. The materials used include 200 female Lohmann MB 202 broilers aged 14 days, with an average body weight of 379.73 ± 18.72 g. The feed ingredients include yellow corn, soybean meal, fish meal, rice bran, fermented lime peel waste flour, soybean oil, premix, CaCO3, D-L Methionine, and L-Lysine. The study was designed using a completely randomized design (CRD) with four levels of fermented lime peel waste flour (FLPWF) usage: 0%, 1%, 2%, and 3% in the ration. Each treatment was repeated five times. Data were analyzed for variance using the SPSS 19.0 software. The results showed that the use of FLPWF did not significantly affect the weight and length of the small intestine, as well as the weight-to-length ratio of the small intestine among treatments (P> 0.05). This study concludes that using fermented lime peel waste flour in rations at 1% to 3% does not reduce the relative weight, length, and weight: length ratio of the small intestine of broiler chickens. Keywords: Broiler, Fermented Lime Peel Waste Flour, Small Intestine

Abstract

The success of educational institutions is influenced by the effectiveness of communication governance within the organization. Effective communication ensures the smooth transmission of information, coordination, and stakeholder engagement. This study aims to analyze the effectiveness of communication governance at SDIT Ash-Shibgoh in improving institutional performance. Using a qualitative approach with interviews conducted with teaching staff, the study explores communication patterns, media used, challenges faced, and their impact on organizational effectiveness. The results indicate that the school has implemented a systematic formal communication structure through hierarchical procedures and utilizes digital technology, such as the Epskul application and WhatsApp, to enhance transparency and efficiency. However, some challenges were identified, including low parental responsiveness to digital information and limited access to technology for some stakeholders. To overcome these obstacles, strategies such as increasing parental involvement, providing communication training for staff, and optimizing the use of technology are recommended. Therefore, effective communication governance plays a crucial role in improving coordination, transparency, and the quality of educational services at SDIT Ash-Shibgoh
