Rancang Bangun Alat Ukur Jarak dan Peringatan pada Visual Docking Guidance System Menggunakan Sensor Lidar

The limited ground marshall, yellow line and others at an airport will affect when parking aircraft. Aviation technology has provided solutions, among others, by attaching to aircraft equipment known as the Visual Docking Guidance System (VDGS), is a tool provided by the airport to help a pilot park his plane without the help of a marshaller to direct the movement of planes to the correct parking. However, not all airports are equipped with sophisticated equipment. So this research aims to create a system that can make it easier for pilots to park aircraft while in Apron. To overcome this problem, a VDGS tool was designed which was designed using a TF Mini Lidar sensor and programmed for aircraft parking systems at pioneering airports. This tool is able to provide information on the distance of the plane as far as 12 meters given a condition that the aircraft will display identification of guidance or collision prevention that will STOP if the aircraft is at a distance of 1-3 meters, and GO identification if the aircraft is at a distance of 4-12 meters so that this tool can serves as a guide to the position of the aircraft when parking right in the designated parking area and prevent aircraft crashes when parking when entering the apron area at the pioneer airport

TDS Sebagai Indikator Solenoid Valve Untuk Simulator Instrumen Pengolah Air Ketel Berbasis Arduino

Salah satu faktor yang mempengaruhi umur pakai ketel uap adalah kualitas air umpannya. Air ketel harus diolah sedemikian rupa sehingga memiliki syarat untuk umpan ketel. Jumlah zat padat terlarut, total dissolve solids (TDS) merupakan bagian dari parameter fisika air. Besarnya jumlah padatan terlarut dalam air ini dapat diukur dengan TDS meter. Persyaratan ini diperlukan untuk mencegah terjadinya endapan yang membentuk kerak, korosi, pembentukan deposit, dan kontaminasi uap. Air baku dilewatkan ke kolom-kolom pengolah air. Output kolom terdiri dua katup (valvesolenoid) yang bekerja membuang air apabila nilai TDS tertentu belum tercapai, dan mengumpankan ke kolom pengolah berikutnya apabila nilai TDS tertentu sudah dipenuhi. Nilai TDS ini sebagai indikator bekerjanya katup. Membuka dan menutupnya katup yang berada di setiap kolom pengolah air ini dikendalikan oleh arduino. Pada ketel bertekanan 2351-2600 psig standart nilai padatan yang terlarut dalam air sebesar 25 ppm. Hasil penelitian menunjukkan Katup A akan terbuka jika nilai TDS ? 25 ppm dan katup B terbuka jika nilai TDS >25 ppm.

Clear sky fraction above Indonesia: an analysis for astronomical site selection

We report a study of cloud cover over Indonesia based on meteorological satellite data, spanning over the past 15 years (from 1996 to 2010) in order to be able to select a new astronomical site capable to host a multi-wavelength astronomical observatory. High spatial resolution of meteorological satellite data acquired from {\it Geostationary Meteorological Satellite 5} ({\it GMS 5}), {\it Geostationary Operational Environmental Satellite 9} ({\it GOES 9}), and {\it Multi-functional Transport Satellite-1R} ({\it MTSAT-1R}) are used to derive yearly average clear fractions over the regions of Indonesia. This parameter is determined from temperature measurement of the IR3 channel (water vapor, 6.7 $\mu$m) for high altitude clouds (cirrus) and from the IR1 channel (10.7 $\mu$m) for lower altitude clouds. Accordingly, an algorithm is developed to detect the corresponding clouds. The results of this study are then adopted to select the best possible sites in Indonesia to be analysed further by performing in situ measurements planned for the coming years. The results suggest that regions of East Nusa Tenggara, located in south-eastern part of Indonesia, are the most promising candidates for such an astronomical site. Yearly clear sky fraction of this regions may reach better than 70 per cent with an uncertainty of 10 per cent.Comment: 15 pages, 13 figures, and 4 table

Climate change affecting oil palm agronomy, and oil palm cultivation increasing climate change, require amelioration

Palm oil is used in various valued commodities and is a large global industry worth over US$ 50 billion annually. Oil palms (OP) are grown commercially in Indonesia and Malaysia and other countries within Latin America and Africa. The large-scale land-use change has high ecological, economic, and social impacts. Tropical countries in particular are affected negatively by climate change (CC) which also has a detrimental impact on OP agronomy, whereas the cultivation of OP increases CC. Amelioration of both is required. The reduced ability to grow OP will reduce CC, which may allow more cultivation tending to increase CC, in a decreasing cycle. OP could be increasingly grown in more suitable regions occurring under CC. Enhancing the soil fauna may compensate for the effect of CC on OP agriculture to some extent. The effect of OP cultivation on CC may be reduced by employing reduced emissions from deforestation and forest degradation plans, for example, by avoiding illegal fire land clearing. Other ameliorating methods are reported herein. More research is required involving good management practices that can offset the increases in CC by OP plantations. Overall, OP-growing countries should support the Paris convention on reducing CC as the most feasible scheme for reducing CC.Portuguese Foundation for Science and Technology (FCT), Grant/Award Number: UID/ BIO/04469/2013, COMPETE 2020 (POCI01-0145-FEDER-006684) and BioTecNorte operation (NORTE-01-0145-FEDER-000004); European Regional Development Fund through Norte2020—Programa Operacional Regional do Norteinfo:eu-repo/semantics/publishedVersio

Health-related quality of life in Indonesian type 2 diabetes mellitus outpatients measured with the Bahasa version of EQ-5D

Objectives To present EuroQol-5D (EQ-5D) index scores in Indonesian type 2 diabetes mellitus (T2DM) outpatients and to investigate the associations between EQ-5D and socio-demographic characteristics and clinical condition. Methods Socio-demographic data were collected by interviewing participants, clinical data were obtained from treating physicians and self-reporting. Participants originated from primary and secondary care facilities in the Java and Sulawesi regions. Ordinal regression analysis was conducted with the quintiles of the EQ-5D index scores as the dependent variable to investigate the multivariate association with the participants’ socio-demographic characteristics and clinical condition. Results 907 participants completed the five-level Indonesian version of the EQ-5D. The mean age of the participants was 59.3 (SD 9.7), and 57% were female. The overall EQ-5D index score was 0.77 (0.75–0.79). Male participants had a higher EQ-5D index score compared to females, and the highest percentage of self-reported health problems was in the pain/ discomfort dimension (61%). Factors identified as being significantly associated with lower EQ-5D index scores were: (i) treatment in secondary care, (ii) lower educational level, (iii) dependency on caregivers, (iv) not undergoing T2DM therapy, and (v) being a housewife. Conclusion This study provides estimates of EQ-5D index scores that can be used in health economic evaluations. As housewives were found to experience more T2DM-related pain/discomfort and anxiety/depression, targeted approaches to reduce these problems should be aimed specifically at this group of patients. Potential approaches could involve diseasespecific-counselors (health literacy partners) who provide routine monitoring of T2DM therapy as well as improved health promotion among T2DM communities
