The contact angle is an important parameter to know whether the surface of the object is hydrophobic or hydrophilic. Hydrophobic is a water-resistant property and has a contact angle between 90 ° -150 °, whereas the hydrophilic has a contact angle value of between 10 ° -90 °. The contact angle is also one of the determinants of a surface wetting. The measurement of contact angle based on digital image processing usually uses a circular shape, because it is assumed the droplets are perfectly circular. In practice liquid droplets are not always perfectly circular, therefore required the calculation contact angel according to the liquid droplet surface. The purpose of this research is build visual basic 6.0 implementation for measurement contact angle on the hydrophobicsurface, hydrophilic as well as on the droplet is not perfect circle based on digital image processing. The implementation was made using a two-loop geometry approach by assuming that the liquid dripped on the test material is in the form of two overlapping circles. The results show that the built application is able to calculate the contact angle on the hydrophobic surface with a maximum difference of 2.4 ° and hydrophilic with a maximum difference of 1.85 ° and capable of measuring the contact angle on a perfectly circular droplet with a maximum difference of 2.59 ° against the default value.To obtain maximum resultsthe digital image processing need to be improved so that the detection of wide spread and droplet height is more accurateSudut kontak merupakan parameter penting untuk mengetahui permukaan benda bersifat hidrofobik atau bersifat hidrofilic. Hidrofobik merupakan sifat anti air dan memiliki sudut kontak antara 90°-150°, sedangkan sifat hidrofilic memiliki nilai sudut kontak antara 10°-90°. Sudut kontak juga merupakan salah satu faktor penentu pembasahan suatu permukaan. Pengukuran sudut kontak berbasis pengolahan citra digital biasanya menggunakan bentuk lingkaran, karena diasumsikan bahwa droplet berbentuk lingkaran sempurna. Pada prakteknya droplet cairan tidak selalu berbentuk lingkaran sempurna oleh karenanya diperlukan perhitungan sudut kontak sesuai dengan permukaan droplet cairan. Tujuan pada penelitian ini yaitu membangun implementasi visual basic 6.0 untuk pengukuran sudut kontak pada permukaan yang bersifat hidrofobik, hidrofilik serta pada droplet tidak lingkaran sempurna berbasis pada pengolahan citra digital.Implementasi dibuat menggunakan pendekatan geometri dua lingkaran dengan mengasumsikan bahwa cairan yang diteteskan pada bahan uji berupa dua lingkaran yang saling tumpang tindih. Hasil yang diperoleh menunjukkan bahwa aplikasi yang dibangun mampu untuk menghitung sudut kontak pada permukaan hidrofobik dengan selisih maksimum 2,4° dan hidrofilik dengan selisih maksimum 1,85° serta mampu melakukan pengukuran sudut kontak pada droplet berbentuk tidak lingkaran sempurna dengan selisih maksimum 2,59° terhadap nilai standar.Untuk memperoleh hasil yang maksimal maka pengolahan citra digital perlu ditingkatkan sehinga deteksi lebar sebaran dan tinggi droplet lebih akurat

The decline in Timorese local garlic yields will have an impact on farmers' income and the existence of the garlic. One of the decline factors is production. The purpose of this study is the implementation of an electric field as a stimulant for garlic growth. The electric field used is an AC electric field with an output frequency of 1.0 kHz. The variation of the electric field used is 1.28 kV/m, 1.55 kV/m. 1.80 kV/m, 2.12 kV/m and 2.48 kV/m. The results showed that exposure to an electric field in garlic resulted in a better germination rate, average germination time, and shoot and root growth rate compared to the control. The treatment of exposure to an electric field of 1.55 kV/m resulted the most optimum in the germination rate, average germination time and growth rate of shoots and roots with the respective values (11.4 ± 0.6) %/etmal, (1.4 ± 0, 1) day, (2.83 ± 0.09) mm/day, and (2.04 ± 0.09) mm/day. Increasing germination, shortening the average germination time and growth rate are expected to increase local Timor garlic production.

ABSTRACTX-ray radiography is an imaging technique that utilizes continuous X-ray radiation that penetrates objects. This technique is a non-destructive technique that is widely used for nondestructive testing in industry and for diagnostics in health. This paper is reported the use of digital micro x-ray radiography equipment which was made by the Physics Department of FMIPA UGM to measure the density of plastic and acrylic materials. For this reason, phantom step wedge is made from acrylic and plastic materials. Density is calculated based on variations in the intensity difference that passes through the step wage phantom. Based on the computation, the result obtained acrylic density value of 0.79 ± 0.01 g / cm3 and plastic density of 0.92 ± 0.01 g / cm3. If the computation of the density value is directly compared to the value of density computation using digital radiography, the digital radiography density value is approxaimetely lower 34.18% for acrylic material and 23.91% for plastic material.

Tingkat pemahaman guru menggunakan mikroskop digital mencapai 90%. Abstract: Biology is a science lesson that studies the life of organisms, including their structure, function and growth. Biology learning needs to add skills using teaching aids or practical such as observing cell shape, cell size, and the movement of microorganisms. Therefore, it is necessary to have a tool in the form of a microscope. The limited availability of microscopes owned by schools causes teachers to be less than optimal in conducting research and teaching. Therefore, it is necessary to optimize the performance of the microscope by converting conventional microscopes to digital ones. Based on these problems, a training on Optimization of Conventional Microscopes to be Digital was held for biology teachers. The training begins with an introduction to the function of each component of the auxiliary equipment such as cameras, lights, and image capture software. Furthermore, training on the installation and operation of image capture software and observations using a digital microscope was carried out. The last training was analysis of images obtained from digital microscopes using Image J software. The evaluation results show that 4 biology teachers have been able to reach level 3, which means that teachers able to use of digital microscopes, use software and image analysis using Image J. The level of understanding of teachers using digital microscopes reaches 90%

Cataract is an eye disorder that is at risk of causing blindness. The risk of blindness can be prevented by detecting cataracts as well as the right action in the form of surgery. Examination of cataracts in the eye poly usually uses equipment in the form of a slit lamp. This equipment is only available in hospitals that have eye poly. The lack of hospitals that have slit lamps will cause the number of cataract sufferers to increase. To be able to help overcome this we need a cataract detection system that is easy to implement. In this research, a classification system based on digital image based on the range of histogram values was made. The equipment used to obtain digital images is the Nikon D90 12.3 Megapixel camera with Nikon 50 mm F1.8 AFD lens. The results obtained indicate that the range values for normal eyes are 29–46, immature eyes 54 - 67 and mature eyes 91 - 121. It appears that mature eyes have the highest range. It is hoped that this method can help detect and classify cataracts based on digital image processing.

Local upland rice (Oryza sativa L.) is a type of cereal crop that has the potential for dry land areas. Farmers in Kupang plant upland rice/local rice that has been consumed and used for generations and is considered by the surrounding community as part of their ancestral heritage. The materials used in this research were local upland rice varieties as a result of exploration. The varieties of six local upland rice of Kupang studied in this research had different rice characters in terms of its weight, volume, density and yield.'Aen Molo' has the highest weight per grain and per 1000 grains, namely 0.024 g and 24.95 g, also the highest volume of 1000 grains of rice is 30 ml, while 'Aen Lekes' has the lowest weight per grain and per 1000 grains, namely 0.020 g and 19.66 g and also the lowest volume of 1000 grains, namely 23 ml. The Iodine test results showed that the local rice of Kupang was classified in the regular or non-glutinous rice group. Meanwhile, Alkali test results show that the six samples of local upland rice have a high gelatinization temperature which indicates that local upland rice in Kupang Regency has high amylose content.

Mata merupakan bagian dari organ manusia yang berfungsi untuk melihat. Meningkatnya usia dapat menyebabkan menurunnya kejernihan lensa dan terjadinya katarak. Penyakit katarak tidak dapat dicegah, namun dapat disembuhkan melalui operasi. Di Indonesia, khususnya pada provinsi Nusa Tenggara Timur (NTT) prevalensi katarak sebesar 2,3% dengan tiga alasan utama penderita katarak belum dioperasi adalah karena ketidaktahuan (41,4%), ketidakmampuan (14,1%), dan ketidakberanian (5,7%). Hal ini akan membuat kebutaan akibat katarak cukup tinggi karena banyak penderita katarak tidak mengetahui dirinya mempunyai penyaki katarak, Oleh karena itu perlunya sistem deteksi katarak sehingga bisa dilakukan tindak lanjut lebih cepat. Tujuan penelitian ini merancang sistem deteksi katarak menggunakan metode ekstraksi indeks warna RGB dengan klasifikasi jarak Euclidean. Peralatan yang digunakan untuk menghasilkan citra digital adalah kamera Nikon D90 12,3 Megapixel dengan lensa AFD Nikon 50 mm F1.8. Hasil yang diperoleh menunjukkan bahwa metode jarak Euklidean ini mampu untuk membedakan citra mata katarak matur, imatur dan mata normal dengan akurasi 89,47%. Sistem ini dapat menjadi salah satu alternatif untuk deteksi penyakit katarak berbasis pengolahan citra digital.
