Judul: Review of Insect Monitoring Techniques to Determine Insect Life Behaviour.
Abstrak: Pertanian merupakan salah satu sektor yang akan terus berlanjut demi keberlangsungan hidup manusia. Salah satu tantangan dalam sektor ini ialah serangan hama dan penyakit tanaman yang dapat menimbulkan kerusakan fisik yang merugikan secara ekonomi dan sosial. Salah satu upaya untuk menekan serangan hama adalah mempelajari perilaku hidup serangga untuk menentukan cara pengendalian yang efektif yang dilakukan dengan monitoring serangga. Penelitian ini bermaksud melakukan tinjauan terhadap berbagai teknik monitoring serangga untuk mengetahui perilaku berbagai jenis serangga hama. Tahapan penelitian ini ialah menjelaskan berbagai jenis teknik monitoring konvensional maupun modern. Teknik konvensional meliputi beberapa jenis perangkap seperti perangkap cahaya, perangkap warna, perangkap jebakan, dan perangkap feromon, sedangkan teknik modern meliputi sistem RADAR (Radio Detection and Ranging) dan LiDAR (Light Detection and Ranging). Kedua jenis teknik monitoring serangga mempunyai kelebihan dan kekurangan masing-masing. Teknik monitoring serangga yang berbeda menunjukan perilaku serangga yang berbeda juga. Keempat jenis perangkap konvensional (perangkap cahaya, perangkap warna, perangkap jebakan, dan perangkap feromon) dapat mengungkap perbedaan perilaku menginfestasi (menyerang) tanaman antar jenis serangga hama yang berbeda. Teknologi modern seperti LIDAR dan RADAR tidak dapat digunakan untuk mengetahui perilaku infestasi serangga dan hanya dapat mengungkap kondisi tajuk tanaman yang sakit baik karena serangan hama atau karena kekeringan., Agriculture is one sector that will continue for human survival. One of the challenges in this sector is pest attacks and plant diseases which can cause physical damage that is economically and socially detrimental. One effort to suppress pest attacks is to study the behavior of insects to determine effective control methods which are carried out by monitoring insects. This research aims to review various insect monitoring techniques to determine the behavior of various types of insect pests. The stage of this research is to explain various types of conventional and modern monitoring techniques. Conventional techniques include several types of traps such as light traps, color traps, pitfall traps, and pheromone traps, while modern techniques include RADAR (Radio Detection and Ranging) and LiDAR (Light Detection and Ranging) systems. Both types of insect monitoring techniques have their respective advantages and disadvantages. Different insect monitoring techniques show different insect behavior. The four types of conventional traps (light traps, color traps, trap traps, and pheromone traps) can reveal differences in plant infestation (attacking) behavior between different types of insect pests. Modern technology such as LIDAR and RADAR cannot be used to determine the behavior of insect infestations and can only reveal the condition of diseased plant crowns either due to pest attacks or due to drought.

Judul: Preparation of Integrated Pest Management Design on Organic Farming Land at Rosy's Veggies Farm Sukabumi
Abstrak: Pertanian organik merupakan salah satu cara budidaya yang dapat mendukung pelestarian lingkungan dan tidak terlepas dari serangan hama. Pengendalian hama terpadu merupakan salah satu upaya untuk mengatasi hama yang menyerang pertanian organik. Rosy's Veggies Farm merupakan salah satu pertanian organik yang belum sepenuhnya menerapkan prinsip pengendalian hama terpadu dalam memantau dan mengendalikan hama. Kegiatan ini bertujuan mengembangkan desain pengendalian hama terpadu yang sesuai dengan pertanian organik di Rosy's Veggies Farm Sukabumi.Kegiatan ini meliputi pemantauan serangga menggunakan 3 jenis perangkap yaitu yellow sticky trap, pitfall trap dan light trap, pengamatan tanaman bergejala pada tanaman brokoli, buncis, dan sawi pahit, dan pengembangan desain pengendalian hama terpadu yang spesifik. Dari hasil perangkap, hama banyak ditemukan pada yellow sticky trap. Hama utama pada brokoli adalah Crocidolomia pavonana dan Myzus persicae, hama pada sawi pahit adalah Bradybaena similaris, Phyllotreta striolata dan Crocidolomia pavonana, hama pada buncis adalah Liriomyza sp. dan Henosepilachna sp. Berdasarkan hasil pengamatan, wawancara dan keterlibatan langsung dalam proses pengendalian hama, maka dapat diusulkan rancangan yang mengikuti pengendalianhama terpadu yaitu pemanfaatan PGPR, musuh alami, agens hayati, pestida nabati, tumpang sari dan biofumigasi., Organic farming has been championed as an environmental friendly farming methods and is align with conservation issues, however, the crops are still not immune from pest attacks. Integrated pest management is one of the efforts to overcome pests that attack organic farming. Rosy's Veggies Farm, an organic farm in Sukabumi, Jawa Barat has not fully implemented the principle of integrated pest management in their pest monitoring and pest management practices. This activity aimsto develop an integrated pest control design that issuitable for organic farming at Rosy's Veggies Farm Sukabumi. This activity includes insect monitoring using 3 types of traps, yellow sticky trap, pitfall trap and light trap, observation of symptomatic plants in broccoli, chickpea and bitter mustard plants, and development of specific integrated pest management designs. From the trap results, many pests were found in the yellow sticky trap. The main pests on broccoli were Crocidolomia pavonana and Myzus persicae, pests on bitter mustard were Bradybaena similaris, Phyllotreta striolata and Crocidolomia pavonana, pests on chickpeas were Liriomyza sp. and Henosepilachna sp. Based on the results of observations, interviews and direct involvement in the pest management process, a design that follows integrated pest control can be proposed, use of PGPR, natural enemies, biological agents, vegetable pesticides, intercropping and biofumigation.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
