Abstract: A Method in Learning Magnetic Substance Characteristics and Identifying Natural Sand Compound Contents Through Basic Principles in Physics. This study was conducted by separating ferrate sand from natural sand in an area in Indramayu Regency in the form of the titanomagnetite Fe2.5Ti0.5O4 compound by means of a magnetic separator with a power of 0.3 tesla. Using this method, the titanomagnetite content of the natural sand was capable of being improved from 32% to 63.6% (for sand in River Cimanuks tributary) based on the analysis using XRD (X-Ray Difractometer) using the GSAS (General Structure Analisis System) program with a Chi2 of 1.454 and Wrp as a correction factor for the difference in the intensity of the two patterns was 0.1142 (11.42%). The value of Chi2 which was almost 1 dan and that of Wrp which was almost 10% showed that the data were acceptable (with a probability of ~0.1). To enhance the titanomagnetite content of the separation product, an extraction-solving process was conducted using HCl 32% and NH4OH 25%. The results of the analysis using XRF (X-Ray Flourosence) showed that the content which was most probably a titanomagnetite compound increased its weight fraction to almost 100%.

Abstract

Demam Berdarah Dengue (DBD) perlu mendapat perhatian serius karena masih menjadi masalah kesehatan di Indonesia dan di beberapa daerah masih sering terjadi kejadian luar biasa. Di Jawa Tengah, kasus DBD cenderung meningkat setiap tahunnya terutama pada tahun 2012. Penelitian ini bertujuan menganalisis parameter entomologi dan menggambarkan jenis tempat penampungan air. Penelitian dilakukan di Kabupaten Grobogan, Purbalingga, Kendal dan Kota Semarang pada bulan Juni - Oktober 2013 desain potong lintang. Survei jentik dilakukan untuk melihat keberadaan tempat penampungan air pada 100 rumah. Masing-masing kabupaten dipilih tiga lokasi desa endemis DBD. Hasil survei digunakan untuk menghitung nilai parameter entomologi. Hasil penelitian menunjukkan bahwa meningkatnya kasus DBD di empat kabupaten/kota terkait dengan keberadaan vektor A. aegypti. Hal ini dibuktikan dengan masih tingginya persentase jumlah rumah yang ditemukan jentik A. aegypti (House Index > 10%) serta tingginya jumlah kontainer ditemukan jentik A. aegypti pada rumah yang dilakukan survei (Breteau Index). Nilai ovitrap index paling tinggi di Desa Kalikabong Kabupaten Purbalingga sebesar 40%. Proporsi controllable site lebih banyak daripada disposable site, berarti rumah tersebut berisiko tinggi sebagai tempat perkembangbiakan nyamuk.Dengue Haemorrhagic Fever (DHF) needs serious attention because it is still a health problem in Indonesia and in recent area DHF caused outbreak. In Central Java, incidence of DHF high every years, especially in 2012. This study aimed to analyze the parameters of entomology and describe types of containers. The study was conducted in Grobogan, Purbalingga, Kendal District and Semarang City in June _ October 2013 with cross-sectional design. Larvae survey had been done in 100 houses in three villages that endemic DHF at every district/city. The survey results are used to calculate parameter entomology. The results showed that existance of DHF cases in four district/city connected with the population of A. aegypti. This matter proved with high percentage of houses that found A. aegypti (House Index > 10%) and the high of container that containing A. aegypti in every houses (Breteau Index). The high of ovitrap index (OI) was 40% in Kalikabong village, Purbalingga district. The proportion of controllable sites more than disposable sites, meaning the house as the high risk of mosquito breeding sites.

Abstract

Cendana {Santalum album L.)merupakan tumbuhan yang termasuk dalam kelompok suku Santalaceae. Sebagai anggota kelompok tumbuhan parasit, pada fase pertumbuhannya cendana memerlukan interaksi dengan tumbuhan lain yang berfungsi sebagai inang, melalui alat-alat kontak yang disebut haustorium. Sistem perakaran cendana, di mana padanya haustoria berkembang, lebih didominasi oleh pertumbuhan horizontal. Jenis tanaman inangnya tidak spesifik, sehingga pemilihan jenis tanaman inang untuk cendana dapat disesuaikan dengan model-model yang akan dikembangkan yaitu model agroforestri atau konservasi.

Abstract

Caulerpa sp. dikenal oleh masyarakat dengan nama Latoh merupakan salah satu rumput laut hijau dan dalam pemanfaatannya hanya mengandalkan pengambilan dari alam. Umumnya sumberdaya yang masih mengandalkan hasil dari alam banyak mengalami kendala, antara lain rendahnya produksi karena ketergantungan pada musim. Hal ini berakibat tidak adanya produksi yang berkelanjutan dan sangat membahayakan kelestarian Caulerpa sp. di alam. Caulerpa tumbuh berkelompok dan dapat dijumpai di kedalaman hingga 200 m. Tumbuhan ini hidup menempel di substrat dasar perairan seperti: pecahan karang, pasir dan lumpur. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perbedaan metode budidaya terhadap pertumbuhan berat Caulerpa sp. pada media pemeliharaan. Perlakuan yang diujikan adalah penanaman dengan metode budidaya di permukaan perairan, kolom perairan dan dasar perairan dengan masing-masing berat awal 50 g/rumpun. Tempat uji yang digunakan kantong plastik berdiameter 50 cm dengan tinggi 100 cm sebanyak 9 buah dan bak perendaman berukuran 150x80x120 cm sebanyak 1 buah. Parameter utama dari penelitian adalah laju pertumbuhan berat rumput laut. Parameter pendukungnya adalah parameter fisika kimia, meliputi : suhu, salinitas, pencahayaan, derajat keasaman, karbon dioksida dan oksigen terlarut. Hasil penelitian ini menunjukkan pencapaian berat akhir Caulerpa sp. pada metode budidaya di permukaan sebesar 62,65 ± 0,48 g dengan laju pertumbuhan spesifik 0,54 ± 0,02 % berat/hari, metode budidaya di kolom air sebesar 53,77 ± 1,13 g dengan laju pertumbuhan spesifik 0,17 ± 0,05 % berat/hari dan metode budidaya di dasar sebesar 50,59 ± 0,46 g dengan laju pertumbuhan spesifik 0,03 ± 0,01 % berat/hari. Berdasarkan hasil yang diperoleh penanaman di permukaan media pemeliharaan menunjukkan pencapaian berat akhir dan laju pertumbuhan spesifik yang lebih tinggi dibandingkan dengan metode budidaya yang lainnya, yaitu di kolom air media pemeliharaan dan metode budidaya di dasar media pemeliharaan. Hal ini disebabkan karena penerimaan cahaya pada metode penanaman di permukaan lebih efektif untuk proses fotosintesis yang selanjutnya dipergunakan di dalam proses metabolisme untuk memproduksi cadangan makanan di dalam rumput laut.Kata Kunci : Caulerpa sp., Metode Budidaya, Pertumbuhan Caulerpa sp. known as latoh is one of many kind of green seaweeds, and its usage only depends by taking from nature. Usually its resource from nature is having many constrains, for example low production rate because of depending on weather condition. This makes no sustainable production and really harming Caulerpa sp. preservation in nature. Caulerpa sp. grows in colony and can be found on depth until 200 m. This plant live by attaching itself on substrate in seabed like rubble, sand, and mud. The purpose of this study was to determine the effect of different cultivation methods on the growth rate Caulerpa sp. in the cultivation media. The plant that used in this study was Caulerpa sp. taken from Jepara waters. Initial weight of seaweed that used for every treatment was 50 g/clump. This study used 9 plastic bags which 50 cm diameters and 100 cm height, a soaking tub which size are 150x80x120 cm. Main parameter in this study was growth rate of Caulerpa sp.. Additional parameters are physical and chemical like temperature, salinity, lighting, pH, CO2 and dissolved oxygen. The weight gain of Caulerpa sp. in surface cultivation method was 62.65 ± 0.48 g with specific growth rate 0.54 ± 0.02 % weight/day, water column cultivation method was 53.77 ± 1.13 g with specific growth rate 0.03 ± 0.01 % weight/day, and water bottom cultivation method was 50.59 ± 0.46 g with specific growth rate 0.03 ± 0.01 % weight/day. According to the result, cultivation surface showed growth rate higher than water column and bottom methods because of surface cultivation method got more light, photosynthesis was more effective, and it can be used to produce food stock in the seaweed.Keywords : Caulerpa sp., Cultivation Methods, Growth

Abstract

Research on gall (including field and laboratory observations and field collecting) have been conducted in the Mounts Gede Pangrano (MGPNP) and Halimun Salak National Parks (MHSNP). This research focused on gall shapes, host plant species, and parts of the host plants infected by galls. The result showed that there were 169 gall numbers in MGNP and 127 numbers in MHSNP have been collected. Distribution of plant species infected by the galls were rather same in the both conservation areas. In MHSNP seven families mostly infected by galls: Araceae, 4 species of 5 gall numbers collection in the family (=4/5), Elaeocarpaceae (5/5), Euphorbiaceae (7/9), Lauraceae (8/11), Moraceae (6/7), Melastomataceae (4/4) and Rubiaceae (9/12). In MGPNP the composition is only fairly different: Araliaceae (4/6),Euphorbiaceae (8/13), Lauraceae (9/12), Melastomataceae (5/6), Moraceae (13/22), Myrtaceae (9/11) and Rubiaceae (6/13). At least 23 gall shapes were found in both locations. The most common shape of galls found in MGNP was irregular, while in MHSNP was globular.Galls were mostly (90%) collected from leaf including peduncles and leaf venations. The other parts included twigs, branches, stems, flowers,and fruits. The most common insect found investing galls (i.e. insect gallers) was the midges (54.4%) followed by mites (18.5%), psyllids (11.1%), thrips (6.3%), coccids (1.9%), and aleurodes (1.9%).
