Abstract

This study was conducted to investigate the effectiveness of Lactobacillus sp and fructooligosaccaride (FOS) to reduce the volatile ammonia formation from chicken excreta and layer slurry. For each treatment-replication, 150 g of fecal material were collected from the poultry farm and placed in 500 ml beaker glass. The fecal sample was then treated with 2% Lactobacillus sp (2.6x106) cfu/g and 2% FOS and covered with plastic wraps. The volatile ammonia contents and pH were measured after one hour of standing (0 d) and repeated at 48 h intervals for 6 d. For the dropping slurry study, 300 g of each layer dropping slurry sample were used. Results indicated that 2% Lactobacillus sp or FOS supplementations in the feces and dropping slurry after 1 h up to 6 d reduced the ammonia odor formation, fecal pH, and moisture content. The Lactobacillus sp and FOS treated manure resulted in increasing  Lactobacillus sp count and reducing in E. coli, Salmonella, and Campylobacter in 6 days for both feces and layer dropping slurry. In addition, reducing moisture content was observed in treated manure. It is concluded that Lactobacillus sp and FOS reduced the volatile ammonia formation and pathogenic bacteria from chicken excreta and layer slurry.

Abstract

Biofuel is an alternative energy to replace fossil fuels. The most popular form of biofuel today is bioethanol. Biofuels are considered as a suitable alternative to fossil fuels because they are more environmentally friendly. Production of bioethanol utilizing thermophilic microorganisms is more profitable because thermophilic microbes generally have the characteristics of being able to use a variety of substrates, low contamination, and resistance to high temperatures. The use of microbial consortia tends to give better results than the use of monoculture isolates to optimize bioethanol yields. The aim of this study was to determine the compatibility and ability of the best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuel. This research is a descriptive research, to test isolates of a consortium of thermophilic bacteria that produce bioethanol. The results of this study showed that consortium isolates tended to give better results than monoculture isolates. The best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuels namely MS 12, 17, 18 produced a bioethanol content of 0.863%.

Abstract

The xylanase enzyme has high commercial value in the industrial sector, including the food industry, animal feed, bleaching of pulp/pulp, lignocellulosic bioconversion as fuel, and in the food industry, namely the cheese, bread and meat industries, while in the non-food industry this can be used in detergents. Xylanase enzymes can be produced from microorganisms, one of which is thermophilic bacteria. Thermophilic bacteria are known to be able to produce thermostable enzymes and proteins that are heat resistant. Xylanase production in compatible bacterial consortia was higher than monoculture. The purpose of this study was to determine the bicultur consortium that has the potential to produce xylanase enzymes. This research is an experimental research. Enzyme activity testing used the Miller method with DNS (Dinitrosalycilic acid) reagent using a completely randomized design (CRD) with 3 repetitions. Data on the results of xylanase activity were analyzed by ANOVA test and DMRT follow-up test with a 5% significance level.The results of the thermophilic bacterial isolates in the consortium that have the potential to produce xylanase enzymes are MS18 & MSS15,  MSS15, MS16 and MS18 & MS16.

Abstract

The main conclusion contains what is the implication to other studies or to the future brought by the study. Xylanase is an enzyme that is widely used in industry because this enzyme can hydrolyze xylan (hemicellulose) into xylo-oligosaccharides and xylose. This enzyme can be produced by thermophilic bacteria. One of the benefits of xylanase is as an environmentally friendly fabric bleaching process (biobleaching). The use of xylanase enzymes can reduce the use of toxic chemicals such as chlorine by about 20-40%. The purpose of this study was to determine the effect of temperature and pH on xylanase production activity using rice straw xylan extract as a substrate and to see the potential of MS 18 thermophilic bacterial xylanase on fabric brightness. This research is a descriptive study with temperature and pH optimization treatment using 6 treatments and 3 replications, respectively. Enzyme activity was measured using a spectrophotometer with a wavelength of 540 nm. The data obtained are displayed in the form of tables and figures. The xylanase potential on the brightness level of the fabric was seen based on the results of the kappa number. The results of this study obtained the optimum temperature of xylanase activity at a temperature of 50℃ with the highest xylanase 3.792 U/mL. while at pH the optimum pH of xylanase activity was found at pH 7 with the highest xylanase production of 4.448 U/mL. The potential of xylanase on the brightness of the fabric based on the results of the kappa number is 2.04 lower than without using xylanase, which is 6.46.

Abstract

AbstractThis study analyzes the development model of the Mekar Sari Joint Business Group (KUBE) in Bengkalis Regency using a maslahah approach. KUBE Mekar Sari, a sewing business entity established in 2021, faces significant challenges in terms of sustainability and independence, particularly related to lax internal management, unsystematic financial management, and minimal member participation and effective external assistance. Using a qualitative approach with a case study method, data was collected through in-depth interviews, observations, and document analysis. Analysis was conducted through the lens of maslahah (maqashid al-syari'ah), encompassing hifz al-Dīn, hifz al-Nafs, hifz al-‘Aql, hifz al-Nasl, and hifz al-Māl. The findings indicate that although KUBE Mekar Sari has internalized ethical values (hifz al-Dīn) and provides work flexibility that supports psychological well-being and family responsibility (hifz al-Nafs and hifz al-Nasl), there is a significant gap in the aspects of asset management (hifz al-māl) and knowledge development/participation (hifz al-‘aql). This study concludes that the KUBE Mekar Sari development model is not yet optimal in achieving holistic well-being due to fundamental weaknesses in internal management and the quality of mentoring. Therefore, it is recommended to strengthen internal management based on maslahah, improve the quality of sustainable mentoring, and develop members' capacity to achieve greater independence and sustainability.Keywords: Cooperative Business Group (KUBE), Maslahah, Economic Empowerment, Case Study, Maqashid al-Syari'ah

Abstract

This study aims to analyze the effectiveness of sharia accounting supervision by the Financial Services Authority (OJK) in preventing illegal financial practices in the Islamic fintech industry in Indonesia, as well as to identify the factors influencing public trust, the weaknesses of the supervisory strategy, and strategic recommendations for strengthening governance and consumer protection. This research uses a qualitative descriptive method with primary data from in-depth interviews with an OJK representative in North Sumatra and secondary data from literature studies, regulations, and previous research. The findings indicate that OJK's multi-layer supervision, which includes pre-operational and operational stages as well as coordination with the Sharia Supervisory Board (DPS), is quite effective but still requires improvement in regulatory adaptation speed to keep up with the rapid innovation of illegal fintech actors (regulatory lag). The three dominant factors influencing public trust are information transparency, the track record of fintech organizers, and community experiences. The main weaknesses of supervision are regulatory lag and low reporting rates by victims due to lack of knowledge or fear. Sharia financial literacy is emphasized as the first line of defense, and OJK North Sumatra has actively conducted education programs reaching Islamic boarding schools and religious study groups. This study recommends structured and continuous communication forums among regulators, fintech organizers, and the public, as well as strengthening technology-based reporting systems and empowering the community as part of the supervision mechanism.
