Pemanfaatan Citra Sentinel-2A untuk Estimasi Produksi Pucuk Teh di Sebagian Kabupaten Karanganyar

Penginderaan jauh saat ini telah berkembang sangat pesat, mulai dari bertambahnya citra baru dan gratis untuk diakses siapa saja hingga pemanfaatanya yang kian bervariasi untuk diaplikasian dalam berbagai bidang tak terkecuali bidang perkebunan. Tujuan dari penelitian ini ialah 1) mengkaji akurasi pemodelan hasil estimasi produksi pucuk teh berbasis transformasi indeks vegetasi (NDVI, SAVI, ARVI), 2) mengkaji kemampuan Citra Sentinel- 2A dalam mengkorelasikan antara variabel estimasi produksi (kerapatan tajuk dan pantulan spektral tanaman teh) dengan beberapa transformasi indeks vegetasi dan 3) mengestimasi produksi pucuk teh di perkebunan teh Kemuning tahun 2016. Hasil akurasi perhitungan estimasi produksi pucuk teh yang didapatkan dari pemanfaatan citra Sentinel-2A tahun 2016 ialah sebesar 58.84% dengan RMSE sebesar 201,105 kg/ha. Citra Sentinel-2A mampu mengkorelasikan hasil estimasi produksi pucuk teh dengan beberapa transformasi indeks vegetasi. Korelasi regresi tertinggi yakni pada produktivitas pucuk teh di lapangan dengan transformasi indeks vegetasi ARVI dengan korelasi regresi sebesar 63% yang mengindikasikan hubungan yang kuat antar dua variabel tersebut. Produksi total atau keseluruhan estimasi produksi pucuk teh perkebunan Kemuning bulan oktober tahun 2016 ialah sebesar 215,041 ton

Gamma Irradiation on Growth and Development of Amorphophallus Muelleri Blume.

Iles-iles (Amorphophallus muelleri Blume) produces apomictic seeds lead to low genetic variation. In order to induce genetic variation, germinated seeds were exposed to Gamma irradiation (Co-60) at doses of 10 to 100 Gy. Seed irradiation was conducted at Center for the Application of Isotope and Irradiation Technology -National Nuclear Energy Agency (CAIRT), Indonesia. Morphology and yield of M1 generation were observed. Results showed that irradiation at a dose of 10 Gy close to LD50 with survival rate 56%. Gamma irradiation at a dose of 10 Gy delayed seeds germination. Germination rates gradually increased and reached maximum at 4 weeks after planting (WAP) for control plants, and 14 WAP of irradiated plants. At 16 WAP, germination rate of 10 Gy irradiated plants was 56% and 84% for those of control plants. Irradiation induced chimera as indicated by short petiole, variegated and abnornal shape of leaflets. Some irradiated plants entered dormancy at 8-10 weeks later than control ones. Prolong vegetative periode lead the plants to produce heavier corms. This study revealed the possibility to induce variation of A. muelleri by using gamma irradition. Keywords: Amorphophallus muelleri, gamma irradiation (Co-60), morphological variation, mutation breedin

Anatomy of Injury Severity and Fatality in Indonesian Traffic Accidents

There has been a steady increase in traffic accidents with major injuries in Indonesia over the last 10 years, especially those with a score higher than 3 on the Abbreviated Injury Scale (AIS). Frontal, side, and rear collisions, as well as pedestrian impact are modes of accident that contribute to the majority of injuries or fatalities. Based on age classification, the 16-30 age group are the most vulnerable road users in Indonesia. Traffic accidents in Indonesia are dominated by motorcycles, which also contribute the highest portion of fatalities and major injuries (AIS score > 3). Most traffic accidents can be attributed to human, road and environmental, or vehicle factors. Careless driving and unruly behavior of the driver are the main causes of accidents in Indonesia. Statistical data and analyses on traffic accidents in Indonesia can be used to develop a comprehensive strategy and policy to reduce the number of fatalities and severe injuries of road accidents in Indonesia. There is a need to balance the high growth of motor vehicles with adequate infrastructure. Good driver education as well as vehicle safety and crashworthiness regulations are required in order to reduce traffic accident fatalities
