Abstract

ABSTRAKPythium sp. sebagai salah satu penyebab penyakit dumping off telah banyak menimbulkan kerusakan. Upayapemanfaatan bahan kunyit (Curcuma domestica ), lengkuas ( Languas galanga) dan kencur (Kaempferia galanga )dilakukan sebagai alternatif pengendalian penyakit tersebut yang bersifat ramah lingkungan. Penelitian ini bertujuanuntuk mengetahui pengaruh ekstrak dari rimpang ketiga jenis tanaman tersebut terhadap Pythium sp. Metode yangdigunakan adalah peracunan media tumbuh PDA dengan menggunakan ekstrak dari rebusan rimpang danmenganalisa respon pertumbuhannya. Hasil penelitian ini menunjukkan bahwa ketiga ekstrak tersebut mampumengendalikan pertumbuhan Pythium sp. pada konsentrasi 20%, 30%, 40% dan 50%. Hasil terbaik ditunjukkanoleh perlakuan lengkuas 50% yang mampu mengendalikan pertumbuhan hingga 64 % pada hari pertama danmenurun menjadi 60%pada hari kedua dan 54%pada hari ketiga.

Abstract

ABSTRACTArthrochista hilaralis is the defoliator pest that caused foliar damage (severity level) up to 97,88% onjabon plantation at HTI Baserah sector and 67,80% at Pantai Cermin community forest. The difference ofseverity level between these location is probably caused by temperature and humidity. The aim of thisresearch was to find the role of temperature and humidity to foliar damage caused by A. hilaralis.Systematic sampling was used to determined the observation plot. There were 5 plots and every plotcontain 100 trees. Observation was done to foliar severity level and abiotic factor (temperature andhumidity). The results show that the temperature has negative correlation (-0,288**) and humidity haspositive correlation (0,303**) to severity level at HTI Baserah but at HR Pantai Cermin showed thattemperature has positive correlation (0,169**) and humidity has negative correlation (-0,187**). Theregression equation between severity level to temperature and humidity at HTI Baserah sector was Y=4,418 – 0,015X1 + 0,014X2 (R= 0,305) and Y= 4,961 0,029X1 0,004X2 (R= 0,187) at HR PantaiCermin.

Abstract

Fulfillment the needs of Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) seeds on the other hand can create an unbalanced ecosystem. The availability of red Jabon seed was becoming a source of food for pests, then it causes an explosion of pests and pathogens. The disease that most often affect red Jabon seeds, both in the nursery and in the field was red leaf spot (antraknose). The initial step to control red leaf spot disease is the identification of causing. Identification method performed by observation of the symptoms in the field, followed by microscopic observation in a laboratory. Based on the identification result, it was known that the disease caused by the fungus Cercospora sp., Colletotrichum sp. and Pestalotia sp. The effect caused by those fungal pathogens was the disruption of the photosynthetic process that ultimately inhibits the growth of red Jabon seeds. The controls which have been done are arranged the watering intensity, isolated the infected seed,and  applied the chemical fungicide.

Abstract

ABSTRACT Efforts to develop control techniques of gall rust disease caused by fungi,Uromycladium tepperianum still need to be continued. This study aims to examine the effectiveness of different types and doses of copper-based and boron-based fungicide formulations in suppressing gall rust disease on sengon. The results showed that both fungicides tested showed different effectiveness. Treatment of CC fungicide at a dose of 10% with both pruning and non pruning within two months were able to suppress gall rust as many as 4.2 pieces. Meanwhile, treatment of PG fungicide at a dose of 10% with pruningwere able to suppress gall as many as of 4.8 pieces, treatment without pruning was only able to suppress tumor about 1.6 pieces. CC fungicide apparently could be applied to suppress gall rust without pruning treatment while PG fungicide combined with pruning treatment was more effective.ABSTRAKSerangan penyakit karat tumor pada sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) yang disebab- kan oleh fungi Uromycladium tepperianum (Sacc.) Mc. Alpin. masih terjadi di hampir semua wilayah pertanaman sengon di Jawa. Upaya pengembangan teknik pengendalian penyakit ini, seperti pengembangan fungisida alternatif masih perlu dilakukan. Tujuan penelitian ialah untuk mengetahui efektivitas jenis dan dosis fungisida hasil formulasi berbasis tembaga dan boron serta pemangkasan yang dilakukan dalam menekan pertumbuhan penyakit karat tumor pada tanaman sengon. Percobaan dilakukan menggunakan rancangan faktorial dalam rancangan acak lengkap dengan tiga faktor, yaitu pemangkasan, jenis fungisida dan dosis yang digunakan. Fungisida sebanyak 10 ml diaplikasikan pada tanaman sengon dengan metode injeksi batang setiap bulan. Hasil penelitian menunjukkan kedua fungisida yang diuji menunjukkan efektivitas yang berbeda. Perlakuan fungisida CC dosis 10% pada tanaman sengon yang dipangkas dan tidak dipangkas dalam waktu dua bulan mampu menekan karat tumor sebesar 4,2 buah. Pada perlakuan fungisida PG dosis 10% pada tanaman yang dipangkas mampu menekan karat tumor sebesar 4,8 buah, tetapi pada sengon yang tidak dipangkas mampu menekan karat tumor sebesar 1,6 buah. Fungisida CC lebih efektif menekan karat tumor pada sengon yang tidak dipangkas sedangkan pada sengon yang dipangkas lebih efektif menggunakan fundisida PG.

Abstract

Commercial and community plantation of sengon commonly know as Moluccan albizia (Falcataria moluccana (Miq.) Barneby and J.W Grimes) requires qualified transplant, but the supply of such transplant seed is constrained by mealybug pest attack in the nursery. The purpose of this study is to identify the mealybug species that attack Moluccan albizia seeds. Observation of the symptoms mealybug attack in the nursery and identification of mealybug species has been performed in the nursery of Forest Research Center, Bogor. The results were mealybug that attack nursery was Ferrisia virgata belong to the famili Pseudococcidae, the Order Hemiptera.  White mealybug colonized the stems and leaves of seeds. The leaves fall and plant wilted when the attack become serous. Predator Curinus coerulus and Coccinella repanda was suggested to be used to control mealybug.
