Abstract

Zingiberaceae merupakan tumbuhan obat yang menjadi komoditas unggulan. Kabupaten Semarang merupakan salah satu sentra distribusi Zingeberaceae. Faktor lingkungan yang mempengaruhi distribusi Zingiberaceae adalah ketinggian tempat, kelembaban, suhu udara, pH tanah, dan intensitas cahaya. Tujuan penelitian ini adalah untuk mengkaji jenis-jenis tumbuhan anggota Zingeberaceae, distribusi Zingiberaceae, dan pengaruh ketinggian tempat terhadap distribusi Zingiberaceae di Kabupaten Semarang. Penelitian dilaksanakan pada bulan September sampai November 2010. Pengambilan sampel tumbuhan famili Zingiberaceae dilakukan di lima kecamatan Kabupaten yang memiliki ketinggian berbeda . Analisis data dilakukan dengan menggunakan indeks nilai penting, derajat konstansi, dan analisis korelasi pengaruh ketinggian tempat terhadap distribusi Zingiberaceae. Dari hasil penelitian didapatkan 12 jenis dan satu varietas tumbuhan anggota Zingeberaceae di Kabupaten Semarang. Jenis yang mempunyai nilai penting tinggi adalah Curcuma domestica (kunyit) dan Amomun cardomomum (kapulaga).  Jenis  yang mempunyai distribusi paling luas di Kabupaten Semarang adalah Amomum cardomomum, Curcuma xanthorrhiza, Curcuma domestica, Zingiber americans dan Zingiber officinale.   Kata kunci : Distribusi, Zingiberaceae, Ketinggian Tempat, Kabupaten Semarang.

Abstract

Thirty sediment samples had been taken from the Tapak Formation of Kedung Randu areas, Banyumas, to reconstruct the diversity of mangrove flora from this area the past. This samples were processed for palynological slides used standard palynology preparation method. The microscopic identification of palynomorphs were done to identify taxa of paleoflora. Fifty-six types of pollen and spores fossils had been identified and 22 types were mangrove pollen-spores fossils. This fossils could be grouped into major mangrove (Zonocostites ramonae/Rhizophora type, Spinizonocolpites echinatus/Nypa fruticans, Florschuetzia levipoli/Soneratia caseolaris and Avicennia type); group of minor mangrove (Retitricolporites sp./Excoecaria sp., Discoidites novaguenensis/Brownlowia type, Camptostemon and Acrostichum aureum), and a group of plant associations (Retitricolporites equatoralis/Calophyllum type, Dicolpopollis sp./Calamus type, Racemonocolpites sp./Oncosperma, Marginipollis concinus/Barringtonia, Pandaniidites sp. /Pandanus, Terminalia catappa, Ilexpollenites sp./Ilex, Stellatopollis sp./Croton type, Acanthaceae type, Cyperaceaepollis/Cyperaceae, Podocarpidites/Podocarpus, Aglaia type, Haloragacidites/ Casuarina and Verrucatosporites usmensis/Stenochlaena palustris. Stenochlaeniidites papuanus and Podocarpus imbricatus were found in the samples. Tapak Formation was included in the last section of the Podocarpus imbricatus/Dacrycarpidites australiensis Zone of Java Palynological Zonation, and this formation was in the age of Late Pliocene towards Pleistocene.   Key word: Tapak Formation; major-minor-plant associations of mangrove; palynological zonation

Abstract

Caisim (Brassica juncea L.) is one of vegetable commodities that has a high commercial value. Many people like it because it has a good taste and it contains several kinds of vitamin and mineral that good for health. This research aims to know the influence of liquid bio organic fertilizer and inorganic fertilizer addition to post harvest product caisim leaf and know the best combination of fertilizer for post harvest product caisim leafquality. Data analysis used is Analysis of Variance (ANOVA) and then continued by test significant different used Duncan Multiple Range Test (DMRT) 95%. The caisim plant that have been harvested then being observed on its fiber content, water content, and physical appearance. The result showed thatthe addition of liquid bio organic fertilizer and inorganic fertilizer has not influence for water content and physical appearance of caisim leaf, but it has an influence on fiber content. Treatment with basic media with the addition of 1 mL + 2,17 g NPK is the best treatment to increase fiber content of caisim leaf Tosakan variety.   Keywords: liquid bio organic fertilizer, caisim, quality of post harvest product

Abstract

Temperatur dan gas belerang di aliran air sekitar sumber air panas dan gas belerang kawasan Gedongsongo Kabupaten Semarang, diduga mempengaruhi struktur komunitas diatom epilitik. Proses keluarnya gas belerang adalah melalui celah celah bebatuan sehingga belerang akan menempel pada bebatuan yang merupakan substrat dari diatom epilitik. Penelitian ini bertujuan untuk mengkaji struktur komunitas diatom epilitik pada aliran air disekitar sumber belerang kawasan Gedongsongo. Pengambilan sample dilakukan dengan metoda “ Stratified Random Sampling “ berdasarkan temperatur, ditentukan empat titik sampling. Faktor fisik kimia diukur secara insitu kecuali analisis kandungan sulfat terlarut dalam air . Berdasarkan indeks keanekaragaman diatom epilitik maka stabilitas komunitas diatom pada aliran air sekitar air panas dan sumber gas belerang adalah sedang, indeks dominansi kecil dan indeks perataan hampir merata.   Kata Kunci : Struktur Komunitas, diatom epilitik, air panas dan belerang.

Abstract

The aim of this research was to examine the possibility of semen cryopreservation using modified TES-Tris yolk citrat (TES-TYC) medium with different egg yolk. Semen fulfilling inclusion  criteria with WHO  criteria was divided into three groups and the sperm motility and vitality was counted as initial data. The semen was then mixed with TES-TYC medium with chicken egg yolk, TES-TYC medium with duck egg yolk and TES-TYC medium with goose egg yolk then cryopreserved in liquid nitrogen. After one mounth the semen was thawed and recount its sperm motility and vitality. Data obtained showed that the motility and vitality of  post freezing sperm cryopreserved with TES-TYC medium with chiken was higher compared to the other medium. It could be concluded that the existenced of chicken egg yolk in TES-TYC medium was better kept sperm integrity during cryopreservation compared with the other medium, hence the existenced of egg yolk as ingredient in TES-TYC medium should be chicken egg yolk.   Key words : motilitas dan vitalitas, medium TES-Tris yolk citrat, kuning telur

Abstract

Penelitian mengenai daya parasitasi Trichogramma australicum Gir. terhadap inang alami dan inang pengganti ini bertujuan untuk mengetahui apakah T. australicum setelah bertahun-tahun dipelihara dengan menggunakan inang pengganti masih mampu memarasiti inang alaminya secara efektif. Penelitian menggunakan Rancangan Acak Lengkap dengan lima kali ulangan. Perlakuan adalah pemarasitan telur penggerek batang tebu Chilo auricilius Dudg dan telur ngengat beras Corcyra cephalonica Staint. Perhitungan data dengan parameter jumlah pemarasitan, penetasan parasitoid, dan kemampuan pemarasitan per individu parasitoid betina. Pemeliharaan T. australicum dengan menggunakan inang pengganti tidak mempengaruhi kemampuan pemarasitan terhadap inang alaminya. Parasitoid T. australicum masih memiliki potensi besar untuk digunakan sebagai agen pengendali hayati penggerek batang tebu, khususnya penggerek batang tebu berkilat C. auricilius. Rata-rata pemarasitan T. australicum terhadap telur C. cephalonica dan telur C. auricilius masing-masing sebesar 96.14% dan 95.0%. Penetasan parasitoid dari telur C. cephalonica dan telur C. auricilius masing-masing sebesar 97.13% dan 96.21%. Daya parasitasi per individu parasitoid betina terhadap telur C. cephalonica dan telur C. auricilius masing-masing sebesar 4.80 dan 4.75. Hasil analisis statistik terhadap semua uji menunjukkan tidak ada beda nyata antara kedua perlakuan.   Key word : daya parasitasi, Trichogramma australicum Gir.
