Abstract

Salah satu upaya yang dilakukan dalam pemenuhan kebutuhan energi listrik  adalah dengan memanfaatkan sumber energi baru dan terbarukan (EBT) seperti : energi matahari dan energi angin sebagai Pembangkit Listrik Tenaga Hibrida (PLTH). Penelitian ini bertujuan menganalisis pengoptimalan pengoperasian sistem PLTH Surya Angin dengan studi  kasus pada PLTH Pantai Baru Bantul menggunakan metode Mix Integer Linear Programming. pengoptimalan bertujuan untuk meminimalkan excess electricity dan memaksimalkan pemanfaatan potensi energi terbarukan dengan memperhatikan batasan-batasan yang terkait dengan kapasitas modul sel surya, kapasitas turbin angin, kapasitas inverter, dan kendala baterai. Permasalahan optimisasi dan batasan operasi diformulasikan sebagai model Mix Integer Linear Programming (MILP) dan diselesaikan menggunakan software optimisasi Tomlab CPLEX. Simulasi model optimisasi menggunakan data pembangkit listrik hibrida surya angin Pantai Baru dilakukan dengan skenario penambahan beban non-critical (dummy) pada sistem pembangkit hibrida. Berdasarkan hasil simulasi didapatkan nilai excess electricity dapat dikurangi dan pemanfaatan energi pada beban dapat dimaksimalkan.   Kata kunci: excess electricity, MILP, pembangkit listrik tenaga hibrida, pengoptimalan

Abstract

Activity function decline become one of the stress causes for elderly that can disturb Activity Daily Living (ADL). The Stress condition makes elderly to  adapted that alteration by using coping strategy, they are Problem Focused Coping (PFC) and Emotional Focused Coping (EFC). The aim of this research is to know the correlation between activity function decline to stress coping strategy in elderly.This research used analytic correlation with cross sectional approach design. Purposive sampling technique was applied to determine sample. Chi-Square statistical analysis was used to analyze the data. The samples who had a part decline were 25 people (83,3%) and the samples who had a total decline were 5 people (16,7%). The quantity samples who used PFC coping strategy was 24 people (80%) and EFC was 6 people (20%).  Based on the Chi square analysis, p value was 0,298. Because p value was more than α (5%) or 0,05, it meant that there were not correlation significantly between  activity function decline to stress coping strategy.There was no correlation between activity function declines to stress coping strategy of elderly in nursing home “Welas Asih”, Singaparna, Tasikmalaya.

Abstract

At majority of developing countries such as Indonesia , Acces society to health medium still very limited. In Indonesia , only there are 0,13 doctor for 1.000 soul, 0,62 nurse for 1.000 soulmand 0,2 midwife for 1.000 soul. In health world, Expert System have a lot of used in assisting diagnosis of some disease. Along with technological growth , health world have also eploited handheld computer (such as PDA, smart phone and also ordinary handphone) to assist helath handling. Technological appearance of java 2 Micro Edition from sun Microsystems, progressively facilitate handheld computer use in PDA and also Handphone to assist various productive application and also amusement. This research purpose for design, implemented and performance test  of handphone expert system of health based with java 2 Micro Edition. This research consisted of three phase. The first phase was scheme of expert system phase. Second phase was implementation of handphone expert system with J2ME program. The third phase was examination of expert system. The examination of expert system software was conducted through alpha test and beta test. Alpha test alpha conducted by system designer while beta test conducted by consumer system. Handphone-based expert system for child health diagnose has been developed using java 2 Micro Edition technology. The system has been implemented in Siemens handphone type C65. The system has been tested with good and reliable results. Expert system based on designed by J2ME technology has been developed and implemented with Siemens handphone type C65 hardware.

Abstract

The phytochemical components of avocado seeds (Persea americana Mill) consist of alkaloids, flavonoids, tannins and saponins, so that they have the potential as antibacterials. The aim of this study was to determine the ability of Persea americana Mill extract to inhibit the growth of Staphylococcus aureus through inhibition zone observation and the ability to accelerate wound healing infected by S. aureus through observation of wound closure and cytopathology.  Persea americana Mill were extracted using maceration method with 70% ethanol. The activities of this extract were tested by diffusion disc agar method. Biomedical tests were carried out on anaestetic Wistar rats whose were S. aureus infected wounds  and treated with Persea Americana Mill extract. Based on the results of the antimicrobial test, avocado seed extract has a inhibitory effect on the growth of S. aureus at a concentration of 6.25% and best at a concentration of 100% compared to the control. Tests in experimental rats showed the effect of wound healing on the 2rd day after giving the extract Persea americana Mill ointment, faster than the control, which was need 4 days of wound closure. Cytopathology results showed that leukocyte activity was more prominent in rats treated with avocado seed extract compared to control rats. Avocado seeds as byproducts have the potential to be new herbal medicines that can be used as antimicrobials of S. aureus which have been confirmed to be resistant to various antibiotics.

Abstract

The purpose of this study was to determine the level of production, availability of food for the community and analyze the level of accessibility of food for households in villages in the district behind Weru Sukoharjo. The method of analysis used in qualitative research is descriptive analytic in order to approach the situation, structure, behavior and performance (SSPP). Use of this approach is based on the consideration of allegations that sensitive (vulnerable) of food a lot happening in the villages left behind. The results of this study indicate that the performance of food production especially rice or rice has increased significantly from year to year, but increased production has not been able to offset the growth in consumption of rice that grows higher than the growth in rice production. This shows that in terms of food availability, food security in the area of research is still very low.
