<p>Rhinoceros beetle (<em>Oryctes rhinoceros</em>) is the main pest of various crops, especially Arecaceae. This research aims to obtain the best growing media of the Arecaceae for the growth of <em>O. rhinoceros </em>larvae. This research expected was designed using a complete randomized design with 5 treatments and 4 replications. The treatment used was different media growth from Arecaceae plants namely palm oil, coconut, sago, and areca, chopped stem, as well as topsoil as control. Parameters measured included individual weight gain of larvae, larval length, a width of <em>O. rhinoceros </em>larvae, with supporting data of soil temperature and humidity, and chemical analysis of organic matter (C-Organic, total N, P-total, and K-Total). The results of the study showed that the growing media of oil palm stem chopped tends to be the most suitable for the growth of <em>O. rhinoceros</em> larvae in case of individual weight increased of larvae (8,8 ± 0,38 g), the length size of larvae (6,15 ± 0,82 cm), and the body width of larvae (1,05 ± 1 cm), and followed by the less and less suitable of the following media growing from chopped stem: coconut, sago, and areca. Thus, oil palms supports the growth of <em>O. rhinoceros</em> more than coconut. This information is important for pest management in smallholders oil palm plantation where oil palms are usually planted along with coconut plants.</p>

Reproductive Activities

The using of palm oil waste had not been optimal lately. It could be seen in oil empty fruit bunches (EFB). It was placed along the oil palm plantations. The condition was not only the trigger of air pollution but also could invite rhinoceros beetle pests (Oryctes rhinoceros) to lay their eggs and carry out reproductive activities due to availability organic matter of the trees. Oil palm plants required large amounts of macro nutrients, especially potassium. However, the potassium nutrient was found in EFB was too slow available because of its relatively long breakdown. That was the reason why it was needed a method of using EFB waste into a capable of high use value product, environmentally friendly, and could give a lot of benefits to oil palm farmers. The purpose of this study was to determine the availability of nutrient content in EFB composting by the using of symbiont bacteria from larvae O. rhinoceros. The research was experimentally conducted a factorial randomized block design (RBD) with 2 factors, namely the type of bacteria and the time of decomposition. The composting stage was carried out by coarsely chopping the EFB then 75 ml of bacterial culture was applied to 1 kg of EFB. Analysis, results indicated C/N ratio (35.56% and 36.97%) and high K content (1.64% and 1.48%). The EFB composting method is achievable in 6 weeks with activators of Bacillus stratosphericus and Bacillus siamensis.

Zinc is an element of many enzymes and hormones having very important physiological functions in the body so that it influences the production and reproduction of animals including the activity of the rumen microflora in degrading fiber in a diet. The aim of this study was to improve the performances of goats offered oil palm fronds based diets through the supplementation of 35 ppm of Zn in the form of inorganic (ZnO) and organic zinc (Zn-methionine). Thirty mature male crossing Boer x Kacang (Boerka) goats were divided into five groups and randomly allocated to one of the five feed treatments as follows: P1: complete feed based on the palm oil fronds (Control), P2: P1 + 35 ppm Zn (100% Zn0), P3: P1 + 35 ppm Zn (75% Zn0 + 25% Zn-methionine), P4: P1 + 35 ppm Zn (50% Zn0 + 50% Zn-methionine), P5: P1 + 35 ppm Zn (25% Zn0 + 75% Zn-methionine). The experiment was conducted in a Completely Randomized Design of six replications. Increasing the proportion of Zn methionine in the mixtures elevated feed consumption, and the highest feed intake was observed in goats received 75% Zn-methionine/25% ZnO. Daily body weight gains was only affected (P&lt;0.05) by the 75% Zn-methionine/25% ZnO supplement. The concentration of Zn in the blood increased significantly (P&lt;0.05) when Zn methionine was added and it increased steadily as the proportion of Zn methionine greater in the mixtures, but the VFA compositions of the rumen were not affected (P&gt;0.05) by Zn supplementation. It is concluded that the performances of goat fed complete diets based on the oil palm fronds could be improved by supplementation of inorganic and organic Zn mixture.

The aim of this study was to evaluate steroid receptors’ status of tumor tissue in different molecular biological types of endometrial cancer (EC), subdivided according to the current classification, and their colonization by lymphocytic and macrophage cells, taking into account body mass index of the patients. Materials and methods: Material from treatment-naive patients with EC (total n = 229) was included; the number of sick persons varied depending on the method used. The average age of patients was close to 60 years, and about 90% of them were postmenopausal. It was possible to divide the results of the work into two main subgroups: a) depending on the molecular biological type of the tumor (determined on the basis of genetic and immunohistochemical analysis), and b) depending on the value of the body mass index (BMI). The latter approach was used in patients with EC type demonstrating a defective mismatch repair of the incorrectly paired nucleotides (MMR-D) and with a type without characteristic molecular profile signs (WCMP), but was not applied (due to the smaller number of patients) in EC types with a POLE gene mutation or with expression of the oncoprotein p53. According to the data obtained, when comparing various types of EC, the lowest values of Allred ER and PR scores were revealed for POLE-mutant and p53 types, while the “triple-negative” variant of the tumor (ER-, PR-, HER2/neu-) was most common in POLE-mutant (45.5% of cases) and WCMP (19.4%) types of EC. The p53+ type of EC is characterized by inclination to the higher expression of the macrophage marker CD68 and lymphocytic Foxp3, as well as mRNA of PD-1 and SALL4. In addition to the said above, for WCMP type of EC is peculiar, on the contrary, a decrease in the expression of lymphocytic markers CD8 (protein) and PD-L1 (mRNA). When assessing the role of BMI, its value of >30.0 (characteristic for obesity) was combined with an inclination to the increase of HER-2/neu expression in the case of MMR-D EC type and to the decrease of HER-2 /neu, FOXp3 and ER expression in WCMP type. Conclusions: The accumulated information (mainly describing here hormonal sensitivity of the tumor tissue and its lymphocytic-macrophage infiltration) additionally confirms our earlier expressed opinion that the differences between women with EC are determined by both the affiliation of the neoplasm to one or another molecular biological type (subdivided according to the contemporary classification), as well as by body mass value and (very likely) the associated hormonal and metabolic attributes.

Development of oil palm plantation on peatland was faced with hydrophobicity problem caused by over drained. Hydrophobicity could reduce water retention and nutrient availability in the peat soil. Beside of proper water management application, addition of soil ameliorant which contain iron could increase stability and improve peat soil fertility. The study was conducted to obtain the effect of steel slag on peat soil properties and hydrophobicity. In this study, peat soil was incorporated with steel slag and incubated in 60 days period. The research was employed completely randomized design (CRD) factorial 2 x 2 x 4. First factor is peat maturity consists of two levels: sapric (S) and hemic (H), while the second factor is soil moisture which also consist of two levels: field capacity (W1) and dry (under the critical water content) (W2). The third factor is steel slag dosage which consist of four levels: 0 g pot (TB0), 7.17 g pot (TB1), 14.81 g -1 -1 pot (TB2), and 22.44 g pot (TB3). The result showed that application of steel slag significantly increase of soil pH, ash content, and water retention at pF 4.2. Furthermore, application of steel slag significantly reduce time for water reabsorption (wettability) in sapric. On the other hand, there are negative corellation between water penetration and soil pH, ash content, and water retention at pF 4.2. Overall, application of steel slag could increase wettability and prevent peat soil hydrophobicity.
