BACTERIAL MER GENES ARE POTENTIAL GENETIC MATERIAL FOR BIOREMEDIATION ON MERCURY POLUTION Suwastika, I Nengah Mercury Mer Gene Blast Remediation Remediation over mercury-contaminated areas become major concern and needs to be solved. Recently, various parts of ecosystem were contaminated because of increase of mercury emission into environment. Methyl-mercury is the most toxic form, which commonly found in contaminated area. This pollutant was rapidly increased due to uncontrolled emission of mercury from power plan, gold mining process and from other sources. The one possible and reasonable method in mercury bioremediation is by using genetically modified plant expressing bacterial-mercury resistance gene. Group of Mer gene was characterized encode mercury transporter and mercury detoxification protein in bacteria. On this study, Blast search on database based on known Mer protein sequence, it shows that these proteins were conserved among bacteria. These groups of genes are potentially to be cloned and transformed into plant for phytoremediation purposes. In order to enhance mercury uptake and reduce its toxicity, multiple genes transformation are considered to be effective approach for transgenic plant construction. This transgenic plant should survive in medium with high concentration of mercury and it should have activities in mercury uptake, detoxification, and Volatilization.

The treatments were PK1 (MS0 + 1 ppm 2,4-D + 10% coconut water), PK2 (MS0 + 1,5 ppm 2,4-D + 10% coconut water), PK3 (MS0 + 2 ppm 2,4-D + 10% coconut water), and PK4 (MS0 + 2,5 ppm 2,4-D + 10% coconut water). Out came of this research showed that all treatments, except PK2, were able to induce callus formation up to 80.55% of total explants. Based on the observed parameters i.e. time of Callus emerging, frecuency of explants producing callus, callus morphology and callus cell observation; PK3 was the best medium in callus induction and growth. Callus on this medium was intermediate-type, white in color, active in  cell propagation, also uniform in size. While PK2 was fail to induce the callus due to overproduction of secondary metabolite.

Children under five age is a group that susceptible to health problems such as lack of energy and protein nutrition, so this age group should get special attentions. One of the problems that should get an attention is problems nutritional status of children. Nutritional status of children is one of the indicators the level of social welfare. The classification of children’s nutritional status was conducted by nutritionist, but the problem is the scattering of nutritionist in Palu is very limited, especially in areas which far away from the city center. This case of study will be taken from Pantoloan Boya village. The limited of nutritionist was being the problems in detecting the indication of malnutrition. Through this research will be made an implementation based of computer system that has a same understanding as a nutritionist who is able to determine the nutritional status of children. One method that can be used in solving the classification of the nutritional status of children is K-Nearest Neighbor (KNN) method. K-Nearest Neighbor (KNN) is one method that use the learning algorithm where the result from the new testing sample is classified based on the majority of KNN’s category. In this research, the system classified the children according to their nutritional status based on data that obtained from the place of research. These results using k = 1 as the number of nearest neighbors which labels the majority of the k nearest neighbors are used to predict the unknown nutritional status of new data. This is because for k = 1 has better accuracy results than other values ​​of k is equal to 81.67%.

Pencegahan penyakit ini menjadi prioritas global karena dapat berakibat kematian pada penderita. Untuk menekan jumlah penderita Demam Berdarah Dengue (DBD) maka dilakukan suatu program yang dapat mengendalikan populasi Aedes aegypti. Teori optimal kontrol diterapkan pada model populasi Aedes aegypti sebagai metode pengendalian secara matematika dengan menerapkan Prinsip Maksimum Pontryagin.Secara biologi, metode pengendalian yang digunakan adalah Sterile Insect Technique (SIT), yang  merupakan teknik pengendalian dengan memberikan mutagen atau radiasi gamma pada nyamuk jantan sehingga menjadi steril. Nyamuk steril inilah yang nantinya akan dilepaskan ke lingkungan untuk kawin dengan nyamuk normal sehingga nyamuk normal akan menjadi steril. Hasil penelitian menunjukkan bahwa program Sterile Insect Technique (SIT) hanya bersifat mensterilkan dan tidak menekan jumlah populasi nyamuk. Untuk itu penelitian ini membahas kombinasi program Sterile Insect Technique (SIT) dan Insektisida yang merupakan teknik pengendalian secara kimia. Hasil penelitian menunjukkan bahwa kombinasi programSIT dan Insektisida dapat membasmi populasi nyamuk dengan baik.

MENGKAJI MODEL PENGENDALIAN POPULASI AEDES AEGYPTI DENGAN STERILE INSECT TEHNIQUE (SIT) DAN KOMBINASINYA DENGAN INSEKTISIDA Wati, I Ratianingsih, R Jaya, Agus Indra Aedes Aegypti Optimal control Sterile Insect Technique Insecticide Pontryagin Maximum Principle. Dengue fever is one of disease which can be transmited by Aedes aegypti. However the prevention on this disease is become global concern. One approche that can be done is by controlling of mosquito population. Related to that issue, this study was done by an application of potryagyn maximum principle in optimal control theory, based on Sterile Insect Technique (SIT). It can be done biologically by introduction of male sterile mosquito (mutan which can be produce by mutagen such as gamma radiation) into the population. It expected that the number of sterile mosquitos will increase by the time. Our result showed that the population of juvenile, immature male and female mosquitos,  fertile male and female, and also sterile male mosquito on the population will grow and reach the stagnan condition after 50 days. Those data indicate that the number of sterile male will increase without any reduction of the population itself. If this method be combained with insecticide chemical method, the population of mosquitos can be reduced/eliminated efectively.

Penelitian tentang komunitas fitoplankton dan kandungan pestisida di Danau Dibawah telah dilakukan dari bulan April sampai September 2014 dengan tujuan untuk melihat komposisi, struktur komunitas fitoplankton dan kandungan pestisida di Danau Dibawah, Kabupaten Solok Sumatera Barat. Penelitian ini dilakukan dengan metode survei pada 5 stasiun pengamatan yang ditetapkan secara porpusive sampling. Sampel plankton dikoleksi menggunakan plankton net berdasarkan ke dalaman perairan kemudian ditarik secara vertikal. Dari hasil penelitian ditemukan 83 jenis terdiri dari lima kelas yaitu Bacillariophyceae (52 jenis), Chlorophyceae (22 jenis), Cyanophyceae (5 jenis), Dinophyceae (3 jenis), dan Euglenophyceae (1 jenis). Kepadatan total seluruh stasiun berkisar dari 898,89 ind./l sampai dengan 2584,93 ind./l dengan kepadatan tertinggi di aliran keluar danau (Stasiun-I) dan terendah di lokasi lahan pertanian (Stasiun III)  meskipun tidak ada residu pestisida yang terdeteksi dalam air. Penelitian ini memperoleh sembilan  jenis fitoplankton yang memiliki kepadatan relatif diatas lima persen (KR >5%) yaitu jenis Aulacoseira granulata, Aulacoseira italica, Epithemia sorex, dan Epithemia sp (Bacillariophyceae) dan Ankistrodesmus falcatus, Desmidium aptogonum, dan Hyalotheca dissiliens (Chlorophyceae),  Anabaena spiroides, dan Chroococcus sp. (Cyanophyceae). Struktur komunitas fitoplankton, Danau Dibawah menunjukkan bahwa kondisi air danau mengalami pencemaran ringan dengan nilai kemerataan yang tinggi sehingga dapat disimpulkan bahwa kondisi danau tidak stabil.
