The Effect of Soil Tillage System and Weeding TIME on the Growth of Weed and Yield of Soybean (Glycine Max (L.) Merril)

The growth and yield of soybeans can decrease due to competition from weeds. Various efforts have been made to control the growth of weeds such as land preparation and weeding periods. An experiment to study the effect of soil tillage systems and weeding time on the growth of weeds and soybean crop yield (Glycine max (L.) Merril) has been done in Wringinsongo Village, Tumpang Sub-District, Malang Regency from February to May 2017. The split-plot design with three replicates was used with the soil tillage system as the main plot consisting of three levels, T0: no tillage, T1: minimum tillage, and T2: conventional tillage, and weeding time as the sub plot consisting of 4 levels, P0: no weeding, P1: weeding 1 time, P2: weeding two times and P3: weeding three times. The results showed that the dominant weed species before treatment were Amaranthus spinosus (Spiny amaranth), Cynodon dactylon (Bermuda grass), Cyperus rotundus (Purple nutsedge), Ageratum conyzoides (Billygoat weed), and Portulaca oleracea (Common purslane). After treatment, the dominant weed species were Cyperus rotundus (Purple nutsedge), Amaranthus spinosus (Spiny amaranth), Ageratum conyzoides (Billygoat weed), Physalis Peruviana (Cape gooseberry), and Eclipta alba (False daisy). There was no significant difference of the dry weight of weeds in conventional tillage followed by weeding 3 times at 15, 30 and 45 days after planting, and minimum tillage and no tillage. For the yield of soybeans, conventional tillage followed by weeding 3 times at 15, 30 and 45 days after planting were not significant with that of minimum tillage. The yield of soybeans was lower than that of with no tillage and no weeding

Pengaruh Jumlah Sekat Filter Udara sebagai Upaya Meningkatkan Performance Mesin Diesel

Penambahan jumlah udara pada proses pembakaran diyakini akan dapat meningkatkan performance dari suatu mesin. Salah satunya dengan mengurangi jumlah sekat pada filter udara. Udara yang masuk ke ruang bakar terlebih dahulu akan di saring melalui filter udara agar selalu terjaga kebersihannya. Hal ini tentu saja merupakan suatu hambatan yang menghalangi udara yang akan masuk kedalam ruang bakar. Dengan pengurangan sekat pada filter udara tersebut maka hambatan yang ada akan semakin berkurang dan udara yang ada untuk proses pembakaran akan terpenuhi sehingga akan terjadi pembakaran yang sempurna. Dengan demikian penelitian bertujuan untuk mengetahui pengaruh jumlah sekat filter udara sebagai upaya meningkatkan performance mesin diesel. Penelitian ini menggunakan metode eksperimen yang menguji jumlah 153 sekat, 144 sekat dan 135 sekat. Dari setiap jumlah sekat dilakukan pengujian menggunakan variasi putaran mesin. Pada jumlah sekat filter udara 153 sekat konsumsi bahan bakar lebih hemat,dan efisiensi juga lebih tinggi. Pada jumlah sekat filter udara 144 sekat, konsumsi bahan bakar,putaran output mesin dan daya engine akan meningkat pula. Pada jumlah sekat filter udara 135 sekat, konsumsi bahan bakar akan menjadi lebih boros tetapi putaran output dan daya engine juga meningkat dengan efisiensi lebih rendah

Automatic Detection and Tracking of Coronal Mass Ejections. II. Multiscale Filtering of Coronagraph Images

Studying CMEs in coronagraph data can be challenging due to their diffuse structure and transient nature, and user-specific biases may be introduced through visual inspection of the images. The large amount of data available from the SOHO, STEREO, and future coronagraph missions, also makes manual cataloguing of CMEs tedious, and so a robust method of detection and analysis is required. This has led to the development of automated CME detection and cata- loguing packages such as CACTus, SEEDS and ARTEMIS. Here we present the development of a new CORIMP (coronal image processing) CME detection and tracking technique that overcomes many of the drawbacks of current catalogues. It works by first employing the dynamic CME separation technique outlined in a companion paper, and then characterising CME structure via a multiscale edge-detection algorithm. The detections are chained through time to determine the CME kinematics and morphological changes as it propagates across the plane-of-sky. The effectiveness of the method is demonstrated by its application to a selection of SOHO/LASCO and STEREO/SECCHI images, as well as to synthetic coronagraph images created from a model corona with a variety of CMEs. The algorithms described in this article are being applied to the whole LASCO and SECCHI datasets, and a catalogue of results will soon be available to the public.Comment: 18 pages, 10 figure
