    Opis:
    This paper discusses the encouragement of creativity and innovation in creating opportunities for entrepreneurship turning useless materials into valuable resources. It is necessary to know the thought process and planning in the entrepreneurship idea to create a new business at this time. One of the brilliant philosophies about entrepreneurs is that they are those who can “turn garbage into gold”. This concept describes the important character of entrepreneurs who foresee business opportunities and have the intelligence to transform trash into cash. This means that they have the necessary ability to create innovation and value-added products for sale. The analyzed case study involves innovation in using fisheries waste specifically derived from crab industries in Indonesia. The study presents empirical perspectives including (1) potential business of crab shell waste (2) technology in innovative use of shell to added value product (3) business analysis and commercialization. Ultimately, we present the concept of a new business by linking theories of entrepreneurial innovation and technology transfer in order to gain environmental balance.

    Opis:
    Introduction and aim. This study aimed to compare the difference in the number of microorganisms (microbial counts) between traditional and disposable bed baths. Material and methods. This study is quasi-experimental with two groups. The sample consisted of 30 respondents from the traditional bed bath and the disposable bed bath groups. Cultures of the groin were obtained to compare the number of microorganisms before and after bathing. Results. Bathing with disposable bed baths has proven to be more effective in reducing the number of microorganisms in both the control group and the intervention group on day I and day II with p=0.014 and p=0.033. Conclusion. Disposable bed baths are more effective in reducing the number of microorganisms on the skin than traditional bed baths.

    Opis:
    Considering the phenomenal growth of network systems, congestion remains a threat to the quality of the service provided in such systems; hence, research on congestion control is still relevant. The Internet research community regards active queue management (AQM) as an effective approach for addressing congestion in network systems. Most of the existing AQM schemes possess static drop patterns and lack a self-adaptation mechanism; as such they do not work well for networks where the traffic load fluctuates. This paper proposes a self-adaptive random early detection (SARED) scheme that smartly adapts its drop pattern based on a current network’s traffic load in order to maintain improved and stable performance. Under light- to moderate-load conditions, SARED operates in nonlinear modes in order to maximize utilization and throughput, while it switches to a linear mode in order to avoid forced drops and congestion under high-load conditions. Our conducted experiments revealed that SARED provides optimal performance regardless of the condition of the traffic load.

    Opis:
    Background. A research was conducted on the ultrasonic pretreatment of chicken droppings for biogas production. The hydrolysis step in anaerobic digestion is rate-limiting and time-consuming due to the presence of complex molecules in the organic wastes. Pretreatment encourages faster digestion and yields improvement by making the organic waste ready for microbial attack. Material and methods. To achieve the optimum sonication time and slurry ratio for maximum biogas production, Response Surface Methodology (RSM) was used in this study. 13 experimental runs were developed according to Central Composite Design with different setup conditions and five replicates at center points to observe the Response, i.e., volumes of biogas produced. This was achieved with the aid of a software package (Design Expert 12.0.1.0). A quadratic model was developed for the responses and a 3D response surface plot was obtained to analyze the effect of the variables and their interactions to determine their optimum levels. Results. The numerical optimization and point prediction result gave a sonication time of 18.6 minutes and a slurry ratio of 2.0 (i.e., 2.0 : 1.0). Under this condition, the predicted maximum volume of biogas production is 24.514 ml in 12 days. This prediction was tested and validated, and the volume of biogas produced under the same conditions was 22.282 ml. This confirmed the adequacy of the predicted model as only a 10.02% error was recorded. Conclusions. Henceforth, the optimum sonication time and slurry ratio were achieved for maximum biogas production from chicken droppings.

    sago starch
    Opis:
    Indonesia is the country with the greatest potential for sago in the world. This research is intended to determine the carbon footprint of sago starch produced from a semi-mechanical process. The calculation was carried out using the LCA approach with the system boundary of cradle to gate. The process steps were carried out in a combination of manual work and diesel-driven engines. The inventory data on material, energy input flows and emissions were obtained from 3 samples of typical medium-scale semi-mechanical sago mills. It was found that the carbon footprint of the sago produced from semi-mechanical processes was 37.9±0.6 kgCO2 eq per 1 ton of dried sago starch. Further analysis shows that 62% of the carbon footprint comes from the extraction stage and 38% from the transportation. It can be estimated that the amount of greenhouse gas emissions from the semi-mechanical sago starch production in Indonesia for 2018 reached around 2,617,639 kg CO2 eq.
