Soil is paramount to sustaining living in biomass production, water quality control, climatic mitigation, and biodiversity endurance. Closely associated with sustainable agriculture, it degrades soil in the long run, robbing the soil of its production capacity and food-generating ability. In Probolinggo, a regency in Indonesia, intensifying the use of chemical fertilizers and pesticides yet a declining trend in yield production was discovered. This research analyzed the acid, nitrogen, organic carbon, and nutrients focusing on phosphor, potassium, iron, and manganese contents. Organic carbon/nitrogen ratio, soil organic compound rate, and cation exchange capacity were also discussed in order to illustrate the correlations among chemical substances and their roles in soil and plant maintenance. While such a study has yet to be performed in Probolinggo, the results should show the degree of land deterioration and future attempts at damage control and correction open to facilitate. Employing a simple random method, soil and plant samples were collected from 18 villages in six districts and their chemical contents were compared to the standard set in Government Regulations No 150/2000. The results showed low N-total, P-Bray, P-Olsen, K, C-Organic, and C/N ratio availabilities at 0.18, 13.88, 14.41, 0.37, 1.36, and 7.38 respectively, contrasted to high rates on pH (5.94), Fe (153.46 mg kg–1) and Mn (37.96 mg kg–1). Biomass production is conclusively imperative to fix the land composition and meet the plant nutrient requirements through an organic approach; fertilizers from digester biogas are therefore recommended. This action requires field agricultural advisors to raise awareness of sustainable agriculture.
Broiler farms in tropical areas have to deal with heat stress. Dried rice, a waste recycle product cheaper than corn, contains resistant starch that is mostly excluded from calorie-emanating metabolism yet advantageous for digestion. This study analyzes its potential to function as heat stress suppressor. Employing completely randomized design of three treatments in five repetitions, variables observed were panting frequency, heart weight, and blood profiles (leukocyte, heterophile, lymphocyte, and H:L ratio). The data gained were run through ANOVA, followed by LSD. T1 was of 100 % basal feed, T2 20 % dried rice spread atop 80 % basal feed, and T3 20 % dried rice thoroughly mixed with 80 % basal feed. The lowest panting frequency was of T2 (2.7 s −1 ), significantly different from T3 (2.9 s−1 ) and T1 (3.1 s −1 ). The lowest heart weight was also of T2 (0.44 mg 100 g −1 ), followed by T3 (0.49 mg 100 g −1 ) and T1 (0.57 mg 100 g −1 ). As of blood properties, the lowest H:L ratio was of T1 (0.22), significantly different from T3 (0.47) and T2 (0.59). To sum it up, dried rice is influential in relieving heat stress in broiler.
This study aimed to analyze the quality of Apis mellifera-produced honey generated from 6 mo old Acacia crassicarpa nectar at 28 d harvest period. The tests referred to the procedures required by the Indonesia National Standard (SNI) 8664-2018. The quality variables tested were of odor and taste and diastase enzyme activity as well as hydroxymethylfurfural (HMF), water, reducing sugar (glucose), sucrose, acid, water insoluble matter, and ash contents. The data were analyzed by using the student t test, where one sample group was prepared to compare each honey quality variable with the quality standard value. The results showed a distinctive smell and taste of honey, enzyme activity > 1.52 DN, HMF 0 mg kg-1, water content 24.2 % w w-1, reducing sugar content 66.56 % w w-1, sucrose content 1.50 % w w-1, acidity 113.05 NaOH kg-1, water insoluble matter content 0.018 % w w-1, and ash content 0.26 % w w-1. It is concluded that the quality variables for honey samples that met the quality requirements were odor and taste, HMF, reducing sugar, sucrose, water insoluble matter, and ash. Meanwhile, those that do not meet the quality requirements are the activity of the attached enzyme, water content and acidity.
This study aims to obtain the incentives strategy that can increase the participation of energy users greater than or equal to 6000-TOE in fulfilling their obligations on energy conservation through energy management with Sustainable Energy Performance (SEP). Several steps need to be carried out. First, data collection on industries that must carry out energy management, and will be analyzed to determine the level of compliance of energy users. Second, ensure that already have carried out an energy-saving program with the SEP. Third, formulating incentive schemes for energy users. Fourth, the interest deduction for the company when they implement the SEP. The results show that only 10.25 % fully comply with the regulation, 36.89 % are partially compliant and 52.87 % are not compliant with energy management activities at all. For industries that have implemented energy conservation and SEP, several benefits are obtained, including capital expenditure (capex) savings when purchasing new imported equipment for creating another energy efficiency, by up to 30 % and incentives in the form of lowering interest rates by up to 4 %.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
