Abstract

Pada penelitan ini dilakukan clustering terhadap gambar head shape nematoda, dalam melakukan pengolahan gambar diperlukan metode ekstraksi fitur untuk menemukan informasi penting dari gambar yang akan diolah, salah satu esktraksi fitur yang bisa digunakan adalah wavelet. Setelah gambar melewati ekstraksi fitur dihasilkan sebanyak 5624 fitur, dengan fitur sebanyak ini dapat mengakibatkan waktu komputasi yang lama. Oleh sebab itu perlu dilakukan reduksi fitur untuk mengurangi jumlah fitur yang awalnya 5624 fitur menjadi 2 atau 3 fitur saja, salah satu metode reduksi fitur terbaru yang bisa digunakan adalah t-SNE. Pada penelitian ini dilakukan perbandingan hasil kualitas cluster antara yang menggunakan reduksi fitur dengan yang tidak. Hasil Silhouette Index   yang didapatkan tanpa reduksi fitur adalah 0.046 dan setelah menggunakan reduksi fitur t-SNE terjadi peningkatan yang cukup signifikan menjadi 0.418.

Abstract

Nematoda genus Helicotylenchus adalah salah satu organisme parasit yang dapat menyebabkan kerusakan pada tanaman dan dapat mengakibatkan penurunan produksi. Untuk genus ini sudah ada kompendium yang mencakup beberapa karakter diagnostik yang dapat dimanfaatkan untuk identifikasi. Akan tetapi, karena tidak ada pengelompokan spesies, maka pemanfaatan itu belum bisa terwujud. Penelitian ini dilakukan untuk melakukan pengelompokan spesies-spesies Helicotylenchus berdasarkan karakter morfologi panjang tubuh, Dorsal Oesophageal Gland Opening (DGO), panjang stilet, jumlah anulus kepala, dan jumlah anulus ekor. Pengelompokan dilakukan dengan memvisualisasi data kisaran setiap karakter menjadi hi-lo-close stock chart dengan menggunakan MS Excel. Hasil pengelompokan dengan karakter panjang tubuh terbentuk enam kelompok, DGO tujuh kelompok, panjang stilet tujuh kelompok, jumlah anulus kepala lima kelompok, dan jumlah anulus ekor lima kelompok. Pengelompokan yang paling jelas adalah berdasarkan karakter panjang tubuh. Pengelompokan ini diharapkan dapat membantu identifikasi nematoda genus Helicotylenchus sehingga kajian mengenai spesies genus ini dapat terfasilitasi.

Abstract

Keberhasilan pertumbuhan tanaman dalam pertanian dipengaruhi oleh beberapa faktor, salah satunya ialah media tanam. Setiap tanaman berbeda kebutuhannya, termasuk jenis media tanam yang tepat untuk dapat tumbuh dan berkembang. Media tanam dapat dikombinasikan untuk mendapatkan berbagai nutrisi yang tepat untuk tanaman dapat tumbuh, berkembang, dan bereproduksi dengan baik. Media tanam yang digunakan petani dalam menunjang pertumbuhan tanaman antara tanah lain, pasir, sekam padi, pupuk, serbuk gergaji, batang pisang, dan cocopeat. Petani saat ini masih mencari jenis media tanam dengan kombinasi yang baru dan berbeda, ini tidak sama antara tanaman satu dan yang lainnya. Setiap tanaman berbeda keperluan nutrisi dan unsur haranya, sehingga berbeda pula kebutuhan media tanam dan komposisinya. Penelitian terkait jenis media tanam dan kombinasinya penting untuk dilakukan, sehingga kedepannya bisa mendapatkan formulasi terbaik tentang media tanam untuk jenis tanaman yang akan ditanam.

Abstract

Cuticular components of female Aedes aegypti from seven localities (populations) in South Kalimantan were compared. Mosquitoes from four populations of Banjarmasin, and one population each of Pelaihari, Barabai, and Kotabaru were sampled. Cuticular hydrocarbons were removed from adult female and were separated and quantified by gas chromatography. Stepwise discriminant analysis determined the degree of differences between populations. Using the concentration of the hydrocarbons in a linear discriminant function and the estimator obtained from cross validation, it was demostrated that specimens could be correctly allocated the population to which they belong with an average success rate of 80.6%. All (100%) specimens of populations outside Banjarmasin were correctly identified. There was reduced segregation of the four Banjarmasin populations, suggesting greater similarity in the hydrocarbons of Aedes aegypti from these populations. It was suggested that the greater similarity correlated with increased contact between populations in the region.

Abstract

Abstract Automatic Ultrafiltration Portable is used to produce clean and ready-to-consume water from a water source in peatlands. Water is one of the factors that really supports the community, including the process of cooking, bathing, washing, and toilet (MCK). The villagers of Jambu Burung and Jambu Raya at the new lucky sub-district use rainwater as drinking water and river water and pond water (well) to meet their daily needs, one of which is in the consumption sector. However, the water in the river that is used by the community is cloudy and smelly, so it is dangerous to health if it is continuously consumed by humans. The quality of clean water is very influential on the results of the quality of human life. The use of river and well water by the guava and guava community has been going on for years, so it is estimated that there are no other alternatives to get proper clean water. So, Automatic Ultrafiltration Portable is one solution to solve this problem. This tool is made based on the need for a portable tool because the size is 40x80x30 cm, practical, and economical, but has good performance (discharge 1 - 5 liters / minute) and can be increased. .

Abstract

Aedes aegypti is the main vector of dengue (DBD) and Chikungunya disease. The mosquito eradication efforts with chemicals has negative impact, there for other alternative with optimal result and less negative effect are needed. One of the natural alternatives materials can be use is Andropogon nardus L. The conduct of this research is to know the effect of Andropogon nardus L on the hatch of egg and pupa mortality of Aedes aegypti. Research use completely randomized design with 5 treatments, which are control (concentration 0%), 5%, 10%, 15% and 20% concentration. The Anava result indicate that Andropogon nardus L with 0% concentration increase the time and level of egg hatch than the 20 % concentration. The Anava pupa mortality result indicate that young pupa have higher lethal amount than old pupa. The conclusion of the research are fragrant grass water can decrease the time and level of egg hatch and increase the mortality of Aedes aegypti pupa.

Abstract

Morphometric analysis of wing venation was performed for discrimination of females of three populations of A e d e s a e g y p ti previously could only be separated by gas chromatographic analysis of cuticular components. Images of detached wings observed under a microscope of low magnification were saved as bitmap files. Cartesian coordinates of termination and branching points of each wing were digitally recorded and were subsequently used in determination of interpoint distances. Two discriminant analyses using standardized distances selected 7 variables that could distinguish females of  the three populations with 86.7% and 85% success rate. The differences in wing measurements gave further evidence of genetic separation of populations of the species.

Abstract

Density and biodiversity of soil nematodes in a discarded coal-mining site in CempakaSubdistrict, Banjar District, South Kalimantan Province, were studied in search for optimumdepth of soil samples taken for nematode community data. Three locations reflecting categories ofconditions were distinguishable in the study area: natural, partially damaged, and damaged. Fromeach location soil samples were taken up to 20 cm depth which were subsequently separated into0-10 and 10-20 cm. Comparisons of soil nematode density and biodiversity were made betweenthe two depth and the three locations. Statistical analyses suggested that natural location had thehighest density of nematodes, followed by the partially damaged and damaged locations. This isparallel to differences among the three conditions in organic-C and pH. However, no significantdifference in nematode density was found between the two depths of soil. Sample-based andindividual-based species accumulation curves showed that more species were found with moresamples and more individuals observed, and upper (0-10 cm) layer has more species than lower(10-20 cm) part of soils. Nevertheless, as the accumulation curves did not reach their asymptotes,more than 10 samples and 600 individuals are required to obtain more accurate informationregarding soil nematode biodiversity in the study area.

Abstract

Indonesia is the richest country in tropical peat lands. Increased population and, in turn,increased basic needs, has led to the use and conversion of peat lands. The success andsustainability of the exploitation requires sufficient knowledge of the properties, includingbiological, of the peat soils. Among key components in soil ecosystem, nematodes have beendemonstrated useful indicator of soil condition. However, few studies have been performed ontheir usefulness in tropical peat soils. In addition to the development of biology and thecontribution of biology to development, being a group with high density in species as well asecological diversity, nematodes provide good possibilities to be useful in biology education,particularly as local contents in peat-land-rich areas. Uniqueness of tropical peat landecosystems requires that certain factors and constraints be considered in the use of nematodes oftropical peat soils in the development of biology and biology education in Indonesia.

Abstract

Temephos has been used for more than 25 years in Banjarmasin as a control measure against Aedes aegypti. As long term use of insecticide may lead to resistance, the present study examined susceptibility and resistance of larval Aedes aegypti from Banjarmasin Utara to temephos (Abate 1SG). Larvae were collected from five sites throughout Banjarmasin Utara Subdistrict and were reared to obtain first and second generations for experiments. Larval mortality due to temephos exposure was determined after 24 hours, and probit analyses were applied to determine LC50 and LC99. The results showed that larval susceptibility were similar among sites, except that from Sungai Jingah which was slightly lower in low dose of temephos. LC99 24 hr was 0.0001 mg/l, which was lower than WHO standard for resistance, indicating that that temephos is still effective larvacide against larvae of  Aedes aegypti from Banjarmasin Utara.
