<![CDATA[ABSTRACT Fruit flies is an important pest for citrus. This research was aimed to determine the effect of (Bractocera dorsalis Hendel.) fruit flies against attractant compounds that contain protein and the height of the trap on the number of catches of fruit flies in the planting of sweet oranges (Citrus sinensis L.). and differences in the sex ratio of fruit flies. This study used a non factorial randomized block design with 9 treatments namely: T0(compound ME 100 cm high), T1(ME compound and cocoa waste 85 cm high), T2(ME compound ME and cocoa waste 135 cm high), T3(ME compound ME and cocoa waste 185 cm high),T4(ME compound and cocoa waste 235 cm high), T5(ME compound and tempe waste 85 cm high), T6(ME compound and tempe waste 135 cm high), T7(ME compound and tempe waste 185 cm high),and T8(ME compound and tempe waste 235 cm high). The results showed that the : type of fruit fly trapped was species of B. dorsalis. In the week four, it was found that the largest population of fruit flies was trapped 155 imago. Treatment cocoa waste was effective in trapping fruit flies in weeks 1-4 with a mean of 12,33 fruit flies and treatment tempe waste trapping fruit flies at week 5 with an average of 8,67 fruit flies. The trap height that is effective at trapping fruit flies is 85 cm. The number of male trapped were 443 males and 19 females with a ratio of 1: 17 and 1 : 26 sex ratio.]]>

<![CDATA[Cellulotic bacteria can be used as breakers of cellulose bonds in rice straw, one of which is cellulotic symbiont bacteria found in the hindgut part of termite Coptotermes curvignathus Holmgren. The study aimed to characterize and identify bacterial isolates from the back intestine of C. curvignathus termites and test the ability of bacterial isolates to decomposition rice straw. The results of isolation on worker caste termites found one bacterial species that was successfully cultured in Carboxylmethil Cellulose (CMC) media. Biochemical test results for isolates, showed that, bacteria found in rod form (rod shape), aerobic, gram negative, motile and produced catalase enzyme. Sequencing of 16S rRNA genes in bacterial isolates showed similarities with Bacillus cereus. A dose of 10 ml symbiont starter, 50% in concentration, applied to 2 kg rice straw can shorten the decomposition time from 12 weeks to 4 weeks, reducing the required decomposition time which is about 75% of the normal time.]]>

<![CDATA[The purpose of this study is the effect of temporary syirkah funds, liabilities and equity of the financing risk and profitability of Islamic banks in Indonesia; analysis of effect financing risk on profitability. The population is Islamic bank in Indonesia. The sample was selected using purposive sampling method. Observation number 11 bank research. Method of data analysis used the path analysis. Results of this study indicate that the fund temporary syirkah positive significant effect on the risk of financing received. The more the amount of funds held temporary syirkah the risk of non-performing loans to finance or Islamic banks NPF indicator becomes smaller. Obligations positive significant effect on the risk of financing. The larger a bank's liabilities, the risk of non-performing loans to the financing or NPF indicator will also be greater. no significant effect on the risk of financing. This means that the level of equity had no impact on the level of financing risk. Fund temporary syirkah positive significant effect on profitability. Obligations positive significant effect on profitability. Debt obligations or received will indirectly increase the amount of income. Equity does not significantly influence the risk of financing. This means that the size of the equity has no effect on the level of profitability and ROA indicators received by commercial banks financing syariah.Risiko significant negative effect on profitability.

<![CDATA[The objectives of this study included: a) To analyze the effect of profitability on ISR disclosures; b) To analyze the effect of company size on ISR disclosures; c) To analyze the effect of profitability, firm size, on ISR Disclosure simultaneously. The population in this study are all companies listed in the Jakarta Islamic Index (JII) for the 2014-2016 period. The variables used in this study include Dependent variable (Y) is Islamic Social Reporting (ISR) (Y) and the independent variable (X) is profitability (X1) and firm size (X2). The method of data analysis uses descriptive statistical analysis and multiple linear regression analysis. Haisl research shows that profitability has a statistically significant effect on ISR, meaning that any increase or decrease in profitability affects the increase in ISR; the size of the company statistically has no effect on ISR, meaning that any increase or decrease in the variable size of the company has no effect on the increase and decrease in ISR.]]>

<![CDATA[AbstractOryctes rhinoceros L. has symbioses with micro organisms in their hind guts which further break down plant material consumed by beetle. The aim of this research is to determine the identification of the existence of the bacterial species in the hind gut larvae of the symbiotic bacteria using biochemical test and analysis based on 16S rRNA. The result of this research indicate that there were two different bacterials: Bacillus siamensis and Bacillus stratosphericus found. The bacteria was used for starting the composting and more specifically, the Bacillus siamensis can speed up composting with the end result at C/N 13.16.Keywords: Larvae O. rhinoceros L, Bacterial Symbionts, 16S rDNA, Composting]]>

<![CDATA[Abstract This research aims to analyze the influence of commissioner independence and sales growth on tax avoidance. The population in this research is automotive sub-sector manufacturing companies listed on the Indonesia Stock Exchange (BEI) during the 2016-2021 period. This study was inspired by the many companies in this sector that practice legal tax avoidance but have the potential to reduce state income. The two independent variables tested are Independent Commissioner and Sales Growth. Sampling was carried out using the purposive sampling method. The data testing technique is to use multiple linear regression analysis. It is hoped that the results of this research will provide an overview of how independent commissioners influence tax avoidance and how sales growth does not influence tax avoidance. Abstrak Penelitian ini bertujuan untuk menganalisis pengaruh independensi komisaris dan pertumbuhan penjualan terhadap penghindaran pajak. Populasi dalam penelitian ini adalah perusahaan manufaktur subsektor otomotif yang terdaftar di Bursa Efek Indonesia (BEI) periode 2016-2021. Penelitian ini dilatarbelakangi oleh banyaknya perusahaan di sektor ini yang melakukan praktik penghindaran pajak secara legal namun berpotensi mengurangi pendapatan negara. Dua variabel independen yang diuji adalah Komisaris Independen dan Pertumbuhan Penjualan. Pengambilan sampel dilakukan dengan menggunakan metode purposive sampling. Teknik pengujian data adalah dengan menggunakan analisis regresi linier berganda. Hasil penelitian ini diharapkan dapat memberikan gambaran bagaimana komisaris independen mempengaruhi penghindaran pajak dan bagaimana pertumbuhan penjualan tidak mempengaruhi penghindaran pajak.]]>

<![CDATA[Ganoderma boninense is a pathogenic fungus that causes the base rot of oil palm trunks. Antagonistic microorganisms can inhibit, suppress, or eliminate populations of plant pathogens. Antagonistic microorganisms can be utilized through symbiotic bacteria. The capability of symbiotic bacteria to degrade cellulose enables them to be more utilized as biological agents for controlling plant pathogens. Oryctes rhinoceros larvae are one of the insects that have symbiotic bacteria. This study aims to analyze the morphological and biochemical characteristics of symbiotic bacteria of O. rhinoceros larvae and see their effectiveness in inhibiting the growth of G. boninense. This research employed a non-factorial completely randomized design with six treatments: S0, Ganoderma boninense (control); S1, G. boninense + isolate of symbiotic bacteria (P2); and S2, G. boninense + isolate of symbiotic bacteria (P3). The results showed that treatment P2 that c, which contains Bacillus subtilis, was able to inhibit G. boninense by 35.21%, and the P3 bacterial isolate, which is Bacillus sp., was able to inhibit the growth of G. boninense by 23.66%. The identification showed that bacteria P2 is B. subtilis, and P3 is Bacillus sp.]]>
