Abstract

This research analyzed the radiometric correction method using SPOT-4 imageries to produce the same reflectance for the same land cover. Top of Atmosphere (TOA) method was applied in previous radiometric correction approach, this TOA approach was upgraded with the reflectance effect from difference satellite viewing angle. The 250 scene of Central Kalimantan SPOT-4 imageries from 2006 until 2012 with varies viewing angle was used. This research applied two-step approaches, the first step is TOA correction, and the second step is normalization using a linear function of reflectance and satellite viewing angle. Gain and offset coefficient of this linear function was calculated using an iterative approach to producing the same reflectance in the forest area. The target of iterative processed is to minimize the standard deviation of a digital number from a forest area in the selected region. The result shows that the standard deviation of a digital number from a forest area in the two steps approach are 8.6, 16.5, and 16.8 for band 1, band 3 and band 4. These values are smaller compared with the standard deviation of digital number result from TOA approach are 15.0, 28,3 and 34.7 for band 1, band 3 and band 4.  Decreasing the standard deviation shows the homogeneity of forest reflectance that could be seen in the seamless result. This algorithm can be applied for making seamless SPOT-4 mosaic whole of Indonesia.

Abstract

IBM's activities implemented in Nusupan Wetan, Celep, Kedawung, Sragen with partners "Rejeki Agung" Ducks Farmer Group Suhardi and Women's Group Livestock (KWT) lstinah. The purpose of activities is to improve the income and welfare of farmers through the production of duck meatballs and duck nuggets in vacuum packs and upgrade magerial, financial management (accounting) and marketing. The method used is counseling, mentoring, training, making meatballs and duck nuggets vacuum packaging storage and business management training. Event was attended by 30 participants from Rejeki Agung duck farmer group and KWT In this activity, given 2 meat grinder tool, 1 cooler box, 1 vacuum machine, 1 Rinnai gas stove, gas cylinders and equipment cookware for making meatballs and nuggets. Results showed dedication that these activities can increase the productivity and income of farmers from selling meatballs partners and nuggets compared to only sell in the form of ducks culled. Additionally meatballs skills and nuggets are also improved with refined taste and variation, as well as increased sales and bookings. And the ability to implement marketing strategies in accordance with the state and have made a simple bookkeeping.

Abstract

Penelitian ini memberikan informasi mengenai kinerja reproduksi kerbau betina di peternakan rakyat Kabupaten Klaten. Penelitian ini telah dilakukan pada April-September 2021 di Kabupaten Klaten. Pengambilan sampel dilakukan dengan metode purposive sampling. Data penelitian ini diperoleh menggunakan teknik wawancara dan observasi dan studi pustaka. Sampel pada penelitian ini adalah 131 ekor kerbau yang dimiliki oleh 30 peternak. Penelitian ini memiliki 5 variabel yaitu umur pertama kali dikawinkan, lama bunting, estrus pertama setelah melahirkan, kawin pertama setelah melahirkan, dan jarak beranak. Hasil penelitian diperoleh data rata-rata umur pertama kali dikawinkan 2,52±0,33 tahun, lama bunting 315,17±14,17 hari, periode estrus pertama setelah melahirkan 93,33±7,45 hari, periode kawin pertama setelah melahirkan 103,33±7,45 hari, dan jarak beranak 408,17±7,45 hari. Hasil penelitian menunjukkan bahwa kinerja reproduksi kerbau rawa di Kabupaten Klaten tergolong baik.
