LATE PLEISTOCENE TO MID-HOLOCENE COASTAL AND INLAND INTERACTION IN THE GUNUNG SEWU KARST, YOGYAKARTA
Get PDFThe Gunung Sewu karst in the Southern Mountains of
Java Island has specific characteristics from a geoarchaeological
viewpoint. Cross disciplinary approaches
utilising Geographic Information Systems (GIS), and
geographical and geological information, are very useful
for examining correlations between site distributions and
geophysical processes. The geographical and geological
aspects of the region contribute information for understanding
prehistoric interactions between coastal and
inland communities. GIS technology was applied in an
examination of terrain, the karst landscape, and the
distributions of cave sites
KONTRIBUSI APLIKASI SISTEM INFORMASI GEOGRAFIS (SIG) DALAM BERBAGAI SKALA KAJIAN ARKEOLOGI LANSEKAP
No full textThe recent development of the Geographical Information System (GIS) has had an impact on archaeological interests, both at the level of estimation and site exploration, presentation of site distribution, various types of spatial analysis and modeling, to the level of archaeological resource management especially for decision making. On the side of archaeological studies, the demands and tough task ahead, is how this discipline is able to access, process and structurize, present, and update all geo-cultural information in the dimensions of form, time and space which are increasingly unlimited in complexity. All forms of geo-cultural information and their dynamics, which are the substance of a landscape condition, require archaeology to "take action" in various scales of multidisciplinary studies. The existence of a comprehensive and structured landscape database, as well as the ability to analyze and evaluate the forms of interrelation between geosphere phenomena, are the basic assets for the success of such studies
Compensatory Growth and Feed Utilization of Humpback Grouper, Cromileptes altivelis Receiving Preset Period of Unfed-Fed Cycle
Get PDFThe effect of preset periods of unfed-fed cycle on growth, feed efficiency and body condition indices of humpback grouper, Cromileptes altivelis was studied. The fish receiving non-feeding/feeding cycle of 1/2 day (T1); 1/2 and 3 days alternately (T2); 1/3 day (T3); were compared to that fed daily as a control (C). Each feeding treatment was assigned to five fiberglass tanks according to a completely randomized design. All fish was weighed to obtain final weight gain at the end of the experiment. Feeding rate (FR) was calculated during feeding period throughout the experiment. At the end of the experiment all fish was weighed to obtain final fish weight. Absolute growth rate (AGR); survival; consumption; cumulative feed consumption, and feed conversion efficiency (FCE) were calculated. Data were subjected to analysis of variance and Tukey test (P<0.05). The results showed that humpback grouper Cromileptes altivelis receiving preset unfed-fed cycle elicited compensatory growth and the fish showed hyperphagia and greater feed conversion efficiency
EFISIENSI SALURAN PEMASARAN KEDELAI PADA BEBERAPA LUAS LAHAN GARAPAN DAN STATUS PETANI (Studi Kasus Petani Pemilik dan Penyewa di Desa Sumberejo Kecamatan Ambulu Kabupaten Jember)
No full textTujuan penelitian ini adalah untuk mengetahui tingkat Efisiensi Saluran Pemasaran Kedelai dan Perbedaan Efisiensi pemasaran pada beberapa status petani, sehingga hubungan antara luas lahan garapan dan saluran pemasaran yang dipilih oleh petani, dan hubungan antara status petani dan saluran pemasaran yang dipilih. Penentuan daerah penelitian ditentukan atas dasar pertimbangan bahwa di Desa Sumberejo Wilayah KUD Sumber Alam merupakan daerah yang berpotensi dalam hal pertanian, sebagian menghasilkan tanaman kedelai.
Saran yang diajukan dari penelitian ini adalah :
(1). Sebaiknya petani dalam menjual hasil produksinya benar-benar memilih saluran pemasaran yang efisien, sebab pemilihan saluran pemasaran yang efisien dapat menyebabkan harga jual yang diterima oleh petani nantinya lebih tinggi, sehingga pendapatan petani akan lebih tinggi.
(2). Untuk meningkatkan pendapatan petani usaha tani kedelai disamping dengan meningkatan hasil produksi dan mutu kedelai juga perlu adanya informasi pasar yang baik dan pembentukan Koperasi yang dapat berfungsi sebagai penampung produksi dan sekaligus membantu mencarikan pemasaran hasil produksinya
PERANCANGAN ANTENA MIKROSTRIP ARRAY CLOVER PATCH PADA FREKUENSI 2,4 GHZ
No full textAbstract—- Microstrip antenna is one type of antenna that has been widely used in laboratories in universities because it is practical and easy to produce. The author uses different amount of clover-shaped patch on two different microstrip antenna with 1×1 and 2×2 format to analyze the parameters on 2.4 GHz operation frequency. Parameter which been analyzed are VSWR, return loss, and bandwidth. In conclusion, the addition of radiating element (patch) of the antenna lower the antenna’s performance in VSWR and Return Loss, but widen the bandwidth of the antenna.Index Terms—Microstrip Antenna, Array Antenna, Clover shaped Patc
Alokasi Energi, Fekunditas, dan Sintasan Larva Cacing Nipah Simpatrik (Polychaeta: Nereididae)
Get PDFTwo species of semelparity Nypa palm worms can only reproduce once during their lifetime lives sympatrically. This reproductive is a unique strategy for allocating energy and fecundity to maximize fertility and larval survival. Information about energy allocation and fecundity of semelparity Nypa palm worms is not yet available. This study aimed to obtain data on the strategy of two species of sympatric Nypa palm worms related to total energy allocation, fecundity, and larval survival. Energy allocation determining by the proportion between reproductive energy and somatic energy. Fecundity was calculated based on the total number of oocytes obtained from the same individual samples used for energy measurement. Larvae survival was counting the trochophore and 3-setigers larvae resulting from fertilization. Energy allocation, fecundity, and survival were analyzed descriptively. The results showed that both sympatric species allocated energy for reproduction. The fecundity of Namalycastis rhodochorde was higher than that of Namalycastis abiuma, but had lower larval survival than N. abiuma. Fecundity in N. rhodochorde is a strategy to compensate for the low survival rate. Meanwhile, N. abiuma had lower fecundity but had high larval survival. Fecundity and larval survival between the two sympatric Nypa palm worm species differed, but both allocated the same energy. Different larval survival yet similar energy allocation is their strategy to survive in the same environmental conditions. Dua spesies cacing nipah semelparitas yang hanya dapat melakukan reproduksi sekali selama hidupnya ditemukan hidup secara simpatrik. Kemampuan adaptasi ini mengindikasikan adanya strategi yang khas dalam mengalokasikan energi dan fekunditasnya sehingga dapat memaksimalkan fertilitas dan sintasan larva, namun informasi tersebut masih belum tersedia. Tujuan penelitian ini untuk mendapatkan data strategi dua spesies cacing nipah simpatrik terkait dengan alokasi energi total, fekunditas, dan sintasan larva. Alokasi energi dideterminasi dengan menghitung proporsi antara energi reproduksi dan energi somatis. Fekunditas dihitung berdasarkan jumlah total oosit yang didapatkan dari sampel individu yang sama dengan yang digunakan untuk pengukuran energi. Penghitungan sintasan dilakukan dengan menghitung jumlah larva trokofor dan larva 3-setiger hasil fertilisasi. Data alokasi energi, fekunditas, dan sintasan dianalisis secara deskriptif. Hasil penelitian menunjukkan kedua spesies simpatrik mengalokasi energi untuk reproduksi. Fekunditas Namalycastis rhodochorde lebih tinggi dibandingkan Namalycastis abiuma, namun memiliki sintasan larva yang lebih rendah dari N. abiuma. Fekunditas pada N. rhodochorde merupakan startegi untuk mengimbangi rendahnya sintasan. Sementara itu, N. abiuma memiliki fekunditas yang lebih rendah namun memiliki sintasan larva yang tinggi. Fekunditas dan sintasan larva antara kedua spesies cacing nipah simpatrik ditemukan berbeda namun keduanya mengalokasi energi yang sama. Perbedaan fekunditas dan sintasan serta persamaan alokasi energi merupakan strategi spesies simpatrik untuk dapat bertahan hidup pada kondisi lingkungan yang sama.
