Judul: Honey Production of UD. Eureka Farm
Abstrak: UD. Eureka adalah unit usaha ternak lebah dengan komoditi madu budidaya, hutan dan koloni serta melakukan pelatihan dan pariwisata lebah yang telah berdiri dari tahun 2014. Tujuan penelitian ini adalah untuk menganalisis produksi madu di UD. Eureka Farm dan kendalanya. Jenis data yang digunakan dalam penelitian ini adalah data primer berbentuk wawancara dan sekunder berbentuk data produksi madu budidaya. Analisis data penelitian ini menggunakan analisis deskriptif. Adapun fokus penelitian yang dianalisis yaitu data produksi madu budidaya dari UD. Eureka. Volume produksi madu UD. Eureka mengalami peningkatan setiap tahunnya namun mengalami penurunan dalam pertumbuhan produksi pada periode 2019 dan 2020 akibat empat faktor kendala yaitu curah hujan tinggi, pengambilan madu oleh koloni lain (madu rampok), perjalanan panjang ke lokasi pengangonan dan kurangnya areal sumber nektar. Hasil analisis data didapatkan bahwa pengaruh lingkungan dan pengetahuan budidaya menjadi faktor yang penting dalam produksi madu. Peran aktif pemerintah daerah untuk melakukan kewajiban dalam pembinaan peternak dan inventariasi data perlebahan penting dilakukan untuk meningkatkan efisiensi dan efektifitas aktifitas budidaya lebah., UD. Eureka is a business unit that concentrate in beekeeping with honey, forest honey, colonies for it’s comodities also trainings for amateur beekeepers and honey-themed tourism which has been formed since 2014. The aim of this study is to analyse honey production and its problems. Type of data being used in this study are prime data in the form of an interview and secondary data in the form of company honey production data. This study uses descriptive analysis. Honey production UD. Eureka has increased every year but experienced a decline in production growth in the 2019-2020 period due to four factor which are heavy rainfall, honey stealing by other colonies (madu rampok), long distance travel to harvest location and limited plants area of nectar source. Results of data analysis showed that the influence of environment and cultivation knowledge became an important factor in honey production. Active role of local governments to carry out obligations in fostering breeders and inventorying data regarding beekeeping is important to increase the efficiency and effectiveness of beekeeping activities. Results of data analysis showed that the influence of environment and cultivation knowledge became an important factor in honey production.

Judul: The Activity of Apis cerana Honey Bee and the Potencial of Food Resources at Surouding Hive Area in Mekarjaya, Pandeglang
Abstrak: Informasi mengenai aktivitas mencari pakan (foraging) dan jenis tanaman sumber pakan penting untuk usaha peningkatan produktivitas lebah madu Apis cerana. Penelitian ini bertujuan menganalisis: (1) pola aktivitas harian lebah A.cerana yang dipengaruhi oleh faktor lingkungan, dan (2) keanekaragaman tanaman sumber polen di sekitar sarang lebah di Desa Mekarjaya, Kabupaten Pandeglang, Banten. Penelitian ini menggunakan dua koloni A. cerana yaitu koloni satu dan koloni dua dengan ukuran koloni yang sama. Perilaku yang diamati yaitu lebah keluar sarang, masuk membawa polen, dan masuk tanpapolen. Hasil pengamatan menunjukkan puncak aktivitas foraging koloni satupada pukul 07.40-08.50 WIB sedangkan koloni dua menunjukan aktivitas foraging yang rendah. Koloni dua melakukan absconding yang terjadi pukul 14.35- 16.30.Rendahnya aktivitas foraging pada koloni dua merupakan sinyal bahwa lebah akan melakukan absconding atau bermigrasi meninggalkan sarang. Hasil analisis vegetasi menunjukkan bahwa tanaman di sekitar sarang merupakan tanaman penghasil polen, nektar, atau polen dan nektar, didominasi oleh Cocos nucifera yang berpotensis menghasilkan polen dan nektar. Indeks keanekaragaman spesies tumbuhan menunjukkan bahwa keanekaragaman tanaman di area tersebut dikategorikan stabil. Hasil analisis jumlah spesies menunjukan bahwa jumlahspesies bernilai mendekati satu, sehingga dikategorikan jumlahnya relatif sama dalam berbagai tegakan., The information on honey bee foraging activities and food sources are important to increase the productivity of Apis cerana. This study aimed to analyze: (1) the daily activity pattern of A. cerana bees that is affected by environmental factors and (2) the diversity of pollen source plants around the beehive at Mekarjaya Village, Pandeglang Regency, Banten. This study used two colonies of A. cerana. The observed behaviors were bees leaving the hive, entering carrying pollen, and entering without pollen. This result showed that the peak of foraging activity in colony one occurs at 07.40-08.50. Colony two showed a low foraging activity that is a signal of the absconding bees or bee migrated. The correlation values between environmental factors: temperature, humidity, and light intensity compared to the honey bee activity was range from 0 to 1. The results of the vegetation analysis showed that the plants around the hive were plants that produce pollen, nectar, or pollen and nectar and the dominant was Cocos nucifera. The plant species diversity index showed that the diversity of plants in the area was categorized as stable. The results of species number analysis were close to one, thus the numbers were categorized as relatively the same in the various stands.

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.
