Abstract

The aim of the research was to determine the morphometry comparison of spermatozoa of simental cattle and ongole cattle such as head length, head width, head area, middle piece length, tail length and overall body length. This research was carried out at the UPTD Laboratory of the Livestock Breeding Center, Horticulture and Animal Husbandry Food Crops Service, Jambi Province. This methodology uses exploration and observation of spermatozoa, using a microscope with a magnification of 400 times. The samples measured were 480 spermatozoa, taken from frozen semen randomly at the Department of Horticultural Food Crops and Livestock, Jambi Province, then smear preparations were made with eosin dye. The variables observed were head length (PK), head width (LK), head area (LKP), middle piece length (PMD), tail length (PE) and overall body length (PTK). The research results showed that the morphometry of simental cattle spermatozoa PK (9.46 µm), LK (5.11 µm), LKP (41.96 µm), MD (13.77 µm), PE (47.68 µm) and PTK ( 70.92 µm). Meanwhile, the size of the spermatozoa of Ongole cattle PK (9.48 µm), LK (5.17 µm), LKP (42.57 µm), MD (13.83 µm), PE (47.96 µm) and PTK (71.28 µm); The statistical results obtained were not significantly different in the morphology of the two cow spermatozoa. The relationship between PTK parameters of simental cattle spermatozoa and PE was very significant (r=0.870) and likewise for Ongole Cow Spermatozoa, the relationship between PTK and PE was very significant (r=0.953). This situation shows that there is a very close relationship between body length and tail length. The percentage of X chromosome simental cattle spermatozoa was (44.38%) and Y chromosome spermatozoa was (55.62%), while the percentage of X chromosome Ongole cattle spermatozoa was (45.83) and Y chromosome carrying spermatozoa was (54.17).

Abstract

Eco-enzyme represents a biological solution derived from the fermentation of organic materials, evaluated for its effectiveness in industrial wastewater treatment. This study examines  to investigate the effectiveness of eco-enzymes in improving the quality of industrial wastewater by analyzing their impact on four specific types of liquid waste: landfill leachate, tofu wastewater, batik wastewater, and laundry wastewater. Samples were treated with eco-enzyme at specific concentrations and incubated for 5 days, followed by chemical analysis. Eco-enzyme reduced ammonia levels in landfill leachate by 57% to 8.83 mg/L, though COD and BOD values rose to 18,114.6 mg/L and 46,709 mg/L, respectively, exceeding effluent standards. In tofu wastewater, COD and BOD decreased by 72% and 75% to 4,189.68 mg/L and 2,395.3 mg/L, respectively, but remained above regulatory limits. Batik wastewater showed increases in most parameters, with COD and BOD reaching 6,838.85 mg/L and 3,193.5 mg/L. For laundry wastewater, surfactants decreased by 55% to 12.97 mg/L, but BOD and TSS increased. These findings indicate that while eco-enzyme can reduce specific pollutants like ammonia and surfactants, its application can also elevate COD and BOD levels in some cases. Additional treatment processes, such as aeration or coagulation, are required to achieve effluent standards. Despite its limitations, eco-enzyme holds potential as an environmentally friendly option for industrial wastewater management when integrated with complementary technologies.

Abstract

This study presents the development and application of an innovative 3-in-1 nanotechnology pyrolysis reactor designed to simultaneously produce liquid smoke, activated carbon, and limestone from locally sourced raw materials in Jambi Province, Indonesia. The multifunctional reactor combines three production processes, which are traditionally performed separately, into a single, efficient unit, addressing both economic and environmental challenges. Coal serves as the primary heat source and material for activated carbon, whereas shell waste is calcined to produce limestone. The reactor operates at temperatures exceeding 550°C to ensure optimal conversion, with a glass wool insulator replacing clay to enhance thermal efficiency. The liquid smoke undergoes further distillation to achieve purification, while residual activated carbon is chemically activated with H₃PO₄ to enhance its adsorption capacity. The experimental results demonstrate that this reactor can produce high-quality products with minimal resource wastage. This 3-in-1 pyrolysis reactor represents a sustainable, cost-effective solution for resource-limited settings, with broad potential for application in waste-to-product conversion, environmental remediation, and rural development.

Abstract

The person who is most responsible for the success of children is their parents. Because children born and raised by parents are the property of parents and cannot be contested. To carry out these heavy obligations, parents must have adequate knowledge and skills in order to achieve what they aspire to be, namely making children pious who are intelligent and of good character. The reality today is that there are still many parents who do not know that their role is very large in educating children so that they do not think and do not even make the maximum effort in educating children. Most parents submit their children's education to other people who are trusted, such as teachers at school, in the course and tutoring, and teachers at the Koran, so they do not pay attention to learning at home. The effect is a lot of personality that is not praiseworthy even failure in learning in school. To overcome this problem, parents and children are coaching through Community Reading Gardens.
