Abstract

Rice is an agricultural product that is the staple food of the Indonesian people, the quality of rice yields is often unsatisfactory, because some of them have empty grains. So that farmers have to separate the filled rice grains from the empty ones manually, this process is considered less efficient. This process takes quite a long time. Therefore, a machine design is needed that can separate the filled grain from the empty grain. This research aims to design a rice fan machine, to make time efficient and to know the comparison between the manual process and the rice separator machine. This tool serves to separate good quality rice grains from grain (empty or imperfect rice grains), so that crop yields can be optimized. The working principle of this tool generally utilizes the difference in density between rice and grain with mechanisms such as air filtration (blower), vibration, or gravity.  In testing, the rice and grain fan showed a high level of accuracy in separation, with a capacity that can be adjusted based on the needs of farmers. This machine is able to separate rice 10kg/minute, which previously only 6kg/hour, there is an increase in the work efficiency of the tool in separating rice.

Abstract

Heart failure with reduced ejection fraction (HFrEF) is a condition associated with high morbidity and mortality. Changes in left ventricular geometry, diastolic function, and cardiac power output (CPO) are key indicators in the management of heart failure. ARNI and ACE inhibitors have been proven effective to treat this condition, but comparative studies on these therapies in the Asian population remain limited. This study was conducted to assess changes in left ventricular geometry, diastolic function, and CPO in heart failure patients following ARNI therapy compared to ACE inhibitors among Indonesian. This observational study employed a prospective cohort design involving 73 heart failure patients divided into two groups: the ARNI group and the ACE inhibitor group. Evaluations were conducted at first admission/recruitment and after three months period of therapy using echocardiography to assess parameters of left ventricular geometry (LVMI and RWT), diastolic function (E/e' ratio), and CPO. The use of ARNI or ACE inhibitors over three months showed a significant reduction in LVMI, accompanied by an improvement in diastolic function marked by a significant decrease in the E/e' ratio (p < 0.05). However, no significant differences were observed between the two groups. CPO values increased in both groups with a p-value < 0.05, where ARNI therapy showed a greater improvement compared to ACE inhibitors (p = 0.048). The use of ARNI and ACE inhibitors in heart failure patients can improve CPO, left ventricular geometry, and diastolic function, with ARNI therapy providing a better enhancement in CPO compared to ACE inhibitors.

Abstract

The Soraya research station is a lowland tropical forest and is included in the management area of the Leuser Ecosystem. This research station has a very high potential for biodiversity. This study aimed to determine the number and types of members of the Dipterocarpaceae tribe and to calculate the quantitative parameters of the plant community. Data collection in this study was carried out using the squared plot method placed randomly at the research location. The analysis used is the Shannon-Wiener diversity index, relative density, relative frequency, relative dominance, and Importance Value Index. The results show that ten species of Dipterocarpaceae belong to various levels of growth, namely seedlings, saplings, poles, and trees. Species of the Dipterocarpaceae spread over 40 plots. Shorea multiflora (Burck) Symington is a species that shows a widespread level and high degree of dominance at the study site. Analysis of plant species diversity using the Shannon-Wiener Index shows that both forest types, primary and secondary, are classified into the high species diversity index.
