Abstract

In Indonesia, soybeans are typically cultivated during the dry season, thus making it prone to drought stress in the reproductive stage. The objective of the research was to characterize the agronomic characters of several soybean genotypes which were tolerant to drought at the reproductive stage. A total of 19 soybean genotypes were evaluated for its agronomic characters and tolerance to drought stress in Probolinggo (East Java, Indonesia) during the dry season (June – September). The research was arranged in a randomized block design with four replicates. Soybean cultivars were sown at two separate experiments, normal/optimal (plants were irrigated during the growth period) and stress (plants were irrigated up to 40 days after planting) conditions. Drought stress during the reproductive stage did not affect the characters of plant height, the number of branches per plant, the number of nodes per plant, and the number of pods per plant. Meanwhile, the number of empty pod, seed weight per plant, and seed yield were significantly affected. There were two genotypes which were identified as the tolerant genotypes to drought stress at the reproductive stage, i.e. MDT15-6-11 and MDT15-W-3034. The agronomic characters of MDT15-6-11 were showed as having a low percentage of yield reduction, hence it was able to mantain its high yield. The MDT15-W-3034 was identified as drought-tolerant due to the slow wilting, high plant character, a slow vegetative phase, and high yields. The genotypes obtained from this study could be recommended to be released as new soybean drought-tolerant varieties due to its high yield and tolerant to drought stress. Those genotypes could also be used as gene donors for soybean improvement to drought stress at the reproductive stage.

Abstract

Vertical distributions of scarabaeids dung beetles (Coleoptera: Scarabaeidae) were studied in a tropical mountaineous rainforest of Gede-Pangrango National Park using human dung traps. Samples were collected at four different altitudes of 500-1000m, 1001-1500, 1501-2000 and 2001-2500m of five different collection sites (Cibodas, Selabintana, Situ Gunung, Bodogol, and Gunung Putri). As many as 1052 individuals of 28 species of scarabaeid dung beetles that belonging to five genera were collected.Onthophagus was the most diverse group, which consists of 21 species (75% of collected species) and followed by Copris with 3 species (10.7%), Paragymnopleurus with 2 species (7.1%), Catharsius with 1 species (3.6%), and Phacosoma with 1 species (3.6%). The Shanon-Winner index of diversity and evenness gradually declined with the increase of altitudes. The different of environment conditions on each altitude might affect to the diversity, abundance, and distribution of dung beetles. The diversity of dung beetles at the interval of 1001-1500m and 1501-2000m were not so high but abundance and similarity were high. Diversity index, evenness, abundance, and species similarity of dung beetles at the interval of 2001-2500m was low because of unfavorable habitat. Although the diversity of dung beetles at the interval 500-1000m was the highest, however abundance and similarity index were relatively low. Analyze of diversity, abundance, evenness, and similarity indexes of dung beetles on each of the different altitudes and environment conditions were discussed in this paper.

Abstract

Study on rattans species density in five sites which were spread out at the submontane forest at altitude from 900 m to 1100 m asl in the northern area of the Gunung Halimun National Park and a non rattan palm exploration around the area were conducted.Each site has a line transect rectangular plots of 200 x 20 m in Cileungsi 1, then 1000 x 20 m in Cileungsi 2, then 650 x 20 m in Cangkuang 1, then 400 x 20 m in Cangkuang 2, and 1000 x 20 m in the Meuncit Kebo Hill. The value of the individual rattans species density per hectar was obtained from the analysis of the number of the individual rattan species occurs in the plots.The result of data analysis above were then inserted into the same rattan density study of the park which was conducted previously.Hence, it was revealed that the park has 21 species of palms consisting of 8 species of Calamus, 4 species of Daemonorops,2 species of Pinanga, 2 species of Caryola, and each one species of Korthalsia, Licuala, Nenga, Plectocomia and Salacca.Four species of palms in the villages out side the park were sagopalm (Metroxylon sagu), coconutpalm (Cocos nucifera), sugarpalm(Arenga pinnata), and chewingpalm (Areca catechu).Three dominant rattans species were Calamus heteroideus, Plectocomia elongata, and C. javensis.Palms which endemic to West Java are Calamus asperrimus, C. melanoloma, Caryota maxima, Nenga pumila, and Salacca zalacca; and the palms which endemic to Java are Daemonorops ruber and Pinanga javana. Among those of 21 species, four species were included as lower risk less concern plant based on the IUCN Red List Categories 30 November 1994 namely D. ruber, C. asperrimus, C.melanoloma, and Licuala pumila; and two species as lower risk near threatened namely Caryota maxima and Pinanga javana.New records natural phenomenas in the park were Calamus heteroideus which has sprouts arising from the tip of the flagelliform staminate inflorescence and from the top of damaged stem; and C. ciliaris which has sprouts arising from its areal stem nodes.And finally, a standard of current local names of the palms in the area were proposed.

Abstract

Pada berbagai genangan air, dari danau sampai air yahg tertampung pada sehelai daun, sering dijumpai jentik-jentik nyamuk. Di samping itu dalam genangan air yang cukup besamya sering terdapat tumbuh-tumbuhan air yang umumnya merupakan gulma. Sebagai penghuni habitat ail yang sama tidak mengherankan bila terjadi hubungan atau saling pengaruh antara tumbuh-tumbuhan dan jentik-jentik tersebut. Beberapa jenis tumbuh-tumbuhan sudah diketahui mempunyai daya bunuh terhadap jentik-jentik nyamuk. Chara,Nitetta dan Utricularia adalah beberapa kelompok tumbuhan rendah yang mempunyai kemampuan sebagai larvisida (Anonim 1973). Akan tetapi kemungkinan tumbuh-tumbuhan tinggi sebagai pengandung daya laivisida belum pernah dijajaki secara tegas (Sen1941). Kenyataan sering didapatinya tumbuhan ail atau gulma pada bermacam-macam bentuk perairan dan pengamatan perorangan yang menyatakan bahwa terdapat kemungkinan pengaruh gulma akuatik terhadap kemampuan wadah untuk menghasilkan nyamuk, merupakan suatu gejala yang perlu dibuktikan kebenarannya secara ilmiah.Pembuktian ini akan bermanfaat dalam kemungkinan penggunaan gejala ini dalam usaha pengendalian populasi nyamuk.Dalam usaha pembuktian ini yang pertama-tama harus dilakukan ialah mengetahui sifat-sifat kualitatif beberapa gulma akuatik terhadap tempat tumbuh jentik-jentik nyamuk.Menuiut Eussen (wawancara pribadi 1975) diketahui adanya eksudan pada beberapa gulma dan pengaruhnya terhadap organisme lain, sebagai contoh eksudan gulma Imperata cylindrica yang menghambat perkecambahan ketimun dan jagung.Macam eksudan yang dikeluarkan dari tiap jenis gulma tidak sama, begitu pula pengaruh macam-macam eksudan itu terhadap organisme lain.Dalam penelitian ini beberapa jenis gulma akuatik dicoba untuk dicari pengaruhnya terhadap tapak penangkaran nyamuk.Dalam percobaan ini digunakan jenis gulma akuatik yang banyak terdapat dalam pertanian, mudah memencar dan tumbuh dalam lingkungan/keadaan ekologi yang bermacam-macam. Selanjutnya perlu diselidiki adanya beberapa gulma akuatik yang mengeluarkan eksudan yang berlainan, baik sebagai penghambat (larvisida) atau pun sebagai penarik (attractant) dan diharapkan eksudan-eksudan itu mempunyai pengaruh yang berbeda terhadap populasi nyamuk.Untuk membedakan pengaruh gulma terhadap tapak penangkaran nyamuk dari pengaruh faktor-faktor lain yang mungkin mempunyai pengaruh sama, dilakukan beberapa percobaan.Percobaan-percobaan ini mencakup perlakuan dengan menggunakan wadah, lokasi, dan ada tidaknya lumpur.Berdasarkan percobaan pendahuluan dapat disimpulkan bahwa warna ember tidak menunjukkan pengaruh terhadap kemampuan nyamuk untuk berbiak pada ember tersebut. Pada percobaan ini yang dihitung dan dianalisis ialah nyamuk dewasa saja, karena tingkat inilah yang sanggup berbiak, menggigit serta menularkan penyakit dan yang menjadi perhatian manusia (BIOTROP 1975).Dalam hal ini jumlah nyamuk induk (imago), telur dan telur yang menetas menjadi larva tidak dihitung, karena segi-segi tersebut sudah di luar ruang lingkup percobaan. Percobaan ini dimaksudkan sebagai penelitian permulaan untuk mengetahui pengaruh gulma akuatik terhadap kemampuan wadah untuk menghasilkan nyamuk.

Abstract

Gunung Halimun National Park is known to be the area of head waters of a number river systems originate. However,there has been no information on fishes diversity at this area.In this regard, a series of ichthyofauna study was conducted from 1996 to 2000. Thirty seven species belonging to 13 families and 26 genera have been found in the rivers and streams in Gunung Halimun National Park and its adjacent area.Gobiidae was dominant, comprising 13 species or 36,36 %, followed by Cyprinidae comprising 5 species or 16.13 %.These Gobioid species were derived from Cisukawayana and Cimaja River, two of the rivers existing in Gunung Halimun National Park which flow south, to the Indian Ocean. In river flowing north i.e, Cikaniki, Ciberang and Cidurian, even from the middle of Cisadane River these fishes were not found. The fishes species which were found in common in rivers flowing north and south were Rasbora aprotaenia,Puntius binotatus, Channa gachua, Clarias batrachus, Poecilia reticulata and Xiphoporus helleri. Up to the present ten fish species were found within the park such as R. aprotaernia, P. binotatus, T. tambra, C. gachua, P. reticulata, P. latipinna, Cyprinus carpio, Monopterus albus, Glyptothorax platypogon and Lentipes sp. It was found that genus Lentipes and Schismatogobius marmoratus extend their range to Java (new record for Java) as well as Rasbora aprotaenia extends its range to southern Java.
