Abstract

This study aims were, first to measure the level of farmers’ willingness to pay the external cost to improve the environment and second, examine the determinant factors. The experiment was conducted in District Sumberjaya and Sekincau, West Lampung District during June-October 2009. Contingent Valuation Method (CVM) was used to answer the first purpose, while ordinal logit regression analysis was used to answer the second purpose. Factors of farmland area, land productivity, household income, educational level, number of family labor, and knowledge of farmers about the benefits of forests had positive influence on WTP while distance of farmers’ house to the forest had negative influence. The increase of WTP was needed to reduce environmental damage due to forest conversion to coffee plantation; moreover, environment improvement hopefully could restore the function of forest where coffee trees were planted.

Abstract

Peremajaan tanaman karet umumnya dilakukan sebelum mencapai 30 tahun karena pertimbangan teknis yang tidak sesuai, dan belum dilengkapi analisis finansial yang tepat. Penelitian bertujuan untuk memperoleh saat dan pola peremajaan optimal tanaman karet serta melihat responnya terhadap perubahan kenaikan biaya dan penurunan harga. Pengambilan sampel dilakukan secara purposive, dilakukan di Kebun Getas, PT. Perkebunan Nusantara IX, Kabupaten Semarang, Jawa Tengah, dengan menggunakan konsep maksimalisasi keuntungan. Hasil penelitian menunjukkan bahwa saat optimal peremajaan tanaman karet adalah saat umur 25 tahun, dan pola optimal peremajaan adalah 4% dari luasan kebun karet. Saat optimal dan pola optimal peremajaan juga tetap, saat dilakukan perubahan kenaikan biaya 5-10% dan penurunan harga 5-10% secara simultan. Meskipun saat dan pola peremajaan optimalnya terjadi pada saat yang sama, namun memiliki perbedaan nilai MNR dan ANR yang semakin rendah seiring dengan turunnya harga dan naiknya biaya. Perusahaan sebaiknya melakukan peremajaan di saat optimal, jika melakukan peremajaan sebelum saat optimal maka belum mencapai keuntungan rata-rata tahunan yang maksimum. Namun kondisi tersebut, tergantung produktivitas tanaman karet, harga jual karet dan biayanya. Perusahaan sebaiknya meremajakan kebun karet sesuai pertimbangan teknis dan finansial, sehingga kebun dapat berlanjut dengan seimbang. Diterima : 2 Maret 2015; Direvisi : 13 April 2015; Disetujui : 20 Mei 2015  How to Cite : Widyasari, T., Hartono, S., & Irham.

Abstract

The increasing of sugarcane productivity and yield is not only affected by factors of production such as seeds, fertilizer, labors, and herbicides. Other factors such as economic orientation and environmental awareness also show their effects on sugarcane productivity and yield. This research was conducted to determine the effect of economic orientation and environmental awareness both on productivity and yield of sugarcane community partners in the Wonolangan Sugar Factory. The study was conducted in Probolinggo and Lumajang Regency with 102 samples of farmers selected using simple random sampling. The measurement of the level of economic orientation and environmental awareness was carried out using Likert scale and was categorized as low, medium and high. The influence of economic orientation and environmental awareness both on productivity and yield of sugar cane were analyzed using multiple regression with the Cobb Douglas production function. Based on the results, the economic orientation and environmental awareness of farmers were relatively high and could increase sugarcane productivity and yield.

Abstract

Comprehensive farm recording, not only recording the inputs used in farming, but also scheduling activities carried out in the process of cultivation. Farming records are important to be owned by farmers as a basis for decision making. Unfortunately, some farmers do not have adequate farming records. In organic farming, farm record is also one of the things required for organic certification. This study aims to determine the response of stakeholders and farmers to Rektanigama, a website-based farm recording application.The number of participant in this research are 27 respondents of stakeholders and 21 respondents of farmers. The research was conducted by census method and focus group discussion  The results showed that stakeholders and farmers considered Rektanigama to be sufficiently good and could be applied as a farm recording tool. Total score for Rektanigama according to farmers was 7.80 and 6.88 according to stakeholders, respectively. In addition, farmers already know the importance of recording farming but have not implemented it. Stakeholders and farmers provide advice that the Rektanigama be disseminated massively to be able to support the needs of farming records, especially for farmers who need organic certification.
