Abstract

ABSTRAK   Penelitian ini bertujuan untuk mengetahui kekayaan dan keragaman jenis semut pada empat tipe habitat dalam kawasan hutan lindung Gunung Nona Ambon dan  mengetahui pengaruh alih fungsi hutan lindung terhadap keragaman semut dalam kawasan. Pengambilan sampel dilakukan pada empat tipe habitat dalam kawasan hutan, masing-masing hutan murni, areal pemukiman, areal pertanian/perkebunan dan areal hutan tanaman. Penelitian dilaksanakan selama tiga bulan menggunakan sistem line transec pada areal seluas 50 ha dengan 3 metode pengambilan sampel yakni menggunakan Pitfall trap, Bait trap dan Soil and Leaf litter sieving. Hasil penelitian menemukan adanya 4 genus dominan pada empat tipe habitat yakni Paratrechina, Pheidole, Lophomyrmex dan Tetraponera. Hasil inventarisasi ditemukan 30 jenis semut dalam areal hutan murni, 17 jenis dalam hutan tanaman, 15 jenis pada areal pertanian/perkebunan dan 5 jenis pada areal pemukiman penduduk. Indeks keragaman jenis semut menunjukkan pada hutan murni sebesar 2,76 disusul areal pertanian/perkebunan 2,07, areal hutan tanaman 1,09 dan areal pemukiman 0,87. Perubahan penggunaan lahan sangat mempengaruhi keragaman semut dalam hal ketersediaan pakan dan kondisi iklim mikro di tiap habitat. Kata kunci : Semut, keragaman jenis, hutan lindung, alih fungsi lahan

Abstract

ABSTRAK Penelitian pengujian enam jenis insektisida nabati terhadap trips (Thrips palmi) pada tanaman kentang dilakukan di Laboratorium Kelompok Peneliti Hama dan Penyakit, Balai Penelitian Tanaman Obat dan Aromatik Bogor, sejak bulan Mei sampai Juli 2010. Penelitian bertujuan untuk memperoleh insektisida nabati yang efektif terhadap hama trips (T. palmi) pada tanaman kentang . Minyak nabati yang digunakan adalah minyak cengkeh, minyak serai wangi, minyak kayu manis, formula minyak cengkeh dan minyak serai wangi (2 formula), serta formula minyak cengkeh dan minyak kayu manis. Minyak cengkeh, serai wangi dan kayu manis sebelum diuji diformulasi dengan xylen dan tween 20 masing-masing formula insektisida nabati konsentrasi 0,5%. Aplikasi dilakukan ke tanaman kentang (Solanum tuberosum) yang sudah diinfestasi dengan trips (T. palmi), masing-masing ulangan 10 ekor. Selanjutnya dikurung dengan kain kasa dan diikat dekat pangkal batang. Pengamatan dilakukan dengan cara menghitung mortalitas trips (T. palmi) pada hari ke 1, 2, 3 dan 4 setelah aplikasi. Penelitian menggunakan rancangan acak lengkap (RAL) dengan 7 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa semua insektisida nabati yang diuji efektif terhadap trips (T. palmi), dengan mortalitas tertinggi 100%. Kata kunci : Enam jenis insektisida nabati, Thrips palmi, tanaman kentang

Abstract

Dinoderus minutus Fabricius (Coleoptera: Bostrichidae) is one of the main pests of wood and bamboo borer. Control of these insects is still dependent on the use of insecticides. This study is a preliminary test for the use of ultrasound frequency as a pest control agent. The research aims to study the effect of ultrasonic frequencies on D. minutus mortality. The method used exposure of ultrasonic frequency to imago D. minutus for 7 days and 14 days indoors with temperatures of 28 °C to 29 °C and humidity of 70% to 81%. Significant results for the ultrasonic frequency treatment which resulted in a D. minutus mortality of 80.00% with a duration of 14 days exposure. The results show that ultrasound frequency with the exact durations can be used as a form of D. minutus control.

Abstract

In December 2019, SARS-CoV-2 caused the coronavirus disease (COVID-19) to spread to all countries, infecting thousands of people and causing death. COVID-19 causes mild illness in most cases, although it can make some people seriously ill. Therefore, vaccines are in various phases of clinical progress, and some of them have been approved for national use. The current state of affairs reveals that there is a critical need for a quick and timely solution to the need for a Covid-19 vaccine. Non-clinical methods such as data mining and machine learning techniques can help to do this. This study will focus on US COVID-19 Vaccination Advances using Machine learning classification algorithms and Using Geospatial analysis to visualize the results. The paper's findings indicate which algorithm is better for a given data set. Naive Bayes algorithm is used to run tests on real world data, and is used to analyze and draw conclusions. Period of Accuracy and performance, and it was found that Naive Bayes is very superior in terms of time and accuracy.

Abstract

Pond apple (Annona glabra L.) belongs to the family of Annonaceae. The seed of A. glabra contains bioactive substance that is toxic to some organisms, however the effectiveness to control wood degrading termites has not yet been scientifically reported. This research analyzes the efficacy of A. glabra seed extract to wood degrading termites. Seed extraction was conducted using n-hexane and ethyl acetate. The paper disc test showed that the extract of A. glabra is toxic to Cryptotermes cynocephalus (dry-wood termites) and Coptotermes curvignathus (subterranean termites). The higher extract concentration (up to 63%) resulted in a higher termite mortality (up to 100%) and lower weight loss of paper sample (less than 1%). Ethyl acetate extract of A. glabra seeds has a better toxicity effect than n-hexane extract against dry wood termites and subterranean termites.
