Sementara itu kurva sintasan spesifik umur (lx) menunjukkan kurva sintasan tipe I. Nilai reproduktif tertinggi (Vx) dicapai oleh betina dewasa pada umur 10 hari, dan jumlah total nilai reproduktif untuk seluruh umur adalah 1335,42. Telur C. coeruleus melewati masa inkubasi selama 7 hari. Stadium larva I sampai dengan IV masing-masing berlangsung selama 6,06; 5,5; 6,11; 8,43 hari. Stadium pupa berlangsung selama 6,66 hari. Jantan dewasa dapat hidup selama 49,08 hari, sementara betina selama 76,99 hari. Selama hidupnya tersebut, betina melewati  periode pre-oviposisi selama 10,57 hari, periode oviposisi selama 30,26  hari, dan periode post-oviposisi selama 24,58 hari. Perbandingan antara jumlah jantan dan betina adalah  1 : 2,83 (jantan 24, betina 68). Pembiakan C. coeruleus di laboratorium dapat dilakukan dengan menggunakan mangsa P. marginatus sebagai mangsa alternatif. C. coeruleus pada area pertanaman pepaya, dimana P. marginatus berada, diduga dapat menetap namun tentunya perlu eksplorasi lanjut mengenai mangsa alternatif setempat.The Development Period and the Balance of Biological Curinus coeruleus Mulsant (Coleoptera: Coccinellidae) : Related to Predation on Paracoccus marginatus Williams and Granara de Willink(Hemiptera: Pseudococcidae) in the LaboratoryABSTRACT. This study aimed to study the developmental and biological balance of predator C. coeruleus in P. marginatus.C. coeruleus has a gross reproductive rate (grr) of 101.934 eggs per female; net reproductive rate (Ro) for 93.776 eggs per female; to increase the intrinsic rate (r) of 0.073 females per female per day; the average generation time (T) during 62.461 days; the doubling time (Dt) for 9.534 days; rate limit increase (l) of 1.075 per day. Meanwhile, age-specific survival curves (lx) shows the survival rate of type I. The highest reproductive value (Vx) was achieved by adult females at the age of 10 days, and the total value for the entire reproductive age is 1335.42. Incubation period of C. coeruleus eggs was 7 days. Larval stages I through IV each lasting for 6.06; 5.5; 6.11; 8.43 days. Pupa stage lasts for 6.66 days. Adult males can live for 49.08 days, while females for 76.99 days. During his lifetime, the female passes the pre-oviposition period for 10.57 days, 30.26 days during the period of oviposition, and post-oviposition period of 24.58 days long. Comparison between the number of males and females is 1: 2.83 (males 24, females 68).  Breeding C. coeruleus in the laboratory can be done using the prey P. marginatus as alternative prey. C. coeruleus in papaya planting area, where P. marginatus are, allegedly to settle but certainly needs further exploration on the local alternative prey.

Penelitian ini bertujuan untuk mengetahui kemampuan amelioran organik dan mikoriza dalam meningkatkan status P tanah dan hasil jagung. Penelitian ini dilaksanakan dengan menggunakan percobaan pot yang ditata menurut rancangan acak kelompok (RAK) faktorial 4 x 2 dengan 3 ulangan. Faktor pertama adalah pemberian amelioran organik yang terdiri atas 4 taraf (jenis) yaitu tanpa amelioran, pupuk kandang, jerami padi dan daun gamal masing-masing sebanyak 20 ton ha-1 atau setara 111 g per polibag. Faktor kedua adalah aplikasi mikoriza dengan 2 taraf yaitu tanpa mikoriza dan pemberian mikoriza sebanyak 10 g per polibag. Hasil penelitian menunjukkan bahwa pemberian amelioran organik dan mikoriza berpengaruh terhadap pH tanah, P total (ekstrak HCl 25 %), P tersedia (Bray 1) dan indek ketersediaan P tanah serta dapat meningkatkan pertumbuhan dan hasil jagung. Kombinasi perlakuan yang memberikan  pengaruh terbaik terhadap status P dan pertumbuhan serta hasil jagung diperoleh pada pemberian pupuk kandang atau daun gamal yang dikombinasi dengan mikoriza. Organic Ameliorant and Mycorrhiza Increase Soil Phosphate Status and Maize Yield on AndisolABSTRACT. A common problem of Andisol soils is the high capacity for P adsorption, although total P content is relatively high. This characteristic causes inefficient use of P fertiliser, to the point that P deficiency can become a major constraint for crop production. This study aimed to determine the effect of organic ameliorants and mycorrhiza on the status of soil phosphate and yield of maize in Andisol.  The experiment was carried out in pots and arranged in a randomized complete block design (RCBD) 4x2 factorial with 3 replications. The first factor is the addition of organic ameliorant consisting of 4 treatments: without ameliorant, manure, rice straw and Gliciridea leaves. The dosage of each ameliorant is 20 ton ha-1 or equivalent to 111 g per polybag. The second factor is the application of mycorrhiza, consisting of 2 levels, no mycorrhiza and mycorrhiza  at 10 g per polybag. The results showed that the application of organic ameliorant and mycorrhiza  affected soil pH, total P (HCl 25% extractable P), available P (Bray 1), and the P availability index and increased the growth and yield of maize in Andisol. The two treatments that provided the most effect on the status of soil phosphate and plant growth and yield of maize were manure, and Glyricidea leaves, in combination with the addition of mycorrhiza.

Recommendation of Potassium Fertilizer Site Specific for Rice PlantABSTRACT. Fertilizer use efficiency is changing greatly depending on soil properties, fertilizer type, irrigation and level of intensive cultivation. A site specific potassium (K) experiment was conducted to formulate the fertilizer recommendation of K for rice plant in different K soil status. The objective of this research were to select a proper soil test method, classify the soil test value of K into two or more classes and fertilizer recommendation of K to rice plant. In this study it was found that the method of NH4OAc 1N pH 7 was the best technique for soil analysis. Based on the method, there are 3 available classes of K i.e. low, medium, and high. The soil with the highest availability of K does not require fertilizing with K, because it has been fulfilled by the water irrigation and straw. The fertilizer recommendation of K for rice plant at medium class is less than low class.

Abstract

Accuracy of Bioassay Technique for Detection of Preemergence Herbicides Ametryn and Diuron in Soil and WaterABSTRACT. The objective of this study is to know the accuracy of the bioassay technique developed to detect ametryn and diuron herbicides in soil and water. Ametryn and diuron are two of several premergence herbicides currently used extensively in Indonesia expecially in plantations crops. The extensive used of the herbicides raised concern about their residue in soil and water and its negative effects. This study is a second step of three steps of experiments aimed to develop a method to detect the amount of herbicides in soil and water using a simple, easy, and economical using bioassay technique. In the previous first step, indicators plant and standard curves for ametryn and diuron were already determined. The objective of this study is to know the accuracy of the bioassay technique to detect ametryn and diuron herbicides in soil and water. Test curve were developed to evaluate accuracy between the amount of herbicide applied compared with the amount calculate of bioassay methods. Test curve is a linier correlation between amount of herbicide applied and the amount detected by bioassay method, stated as Y = a + bX, Y is the amount calculate by bioassay and X is the amount applied. If the amount calculate by bioassay is the same as the amount applied, the test cuve become Y = X, so a must be equal to 0 and b equal to 1 (a=0 and b=1), which means the bioassay method is accurate. Result showed that bioassay could be used to detect ametryn accurately in soil using caisim as indicator-plant, by measuring its shoot length or shoot dry weight. However, this indicator plant could not detect ametryn in water accurately. Bioassay could also be used to detect diuuron accurately both in soil and in water using cucumber as indicator-plant, by measuring its shoot or root length, as well as shoot or root dry weight.
