“…Produktivitas parsial adalah produksi rata-rata dari suatu faktor produksi yang diukur sebagai hasil bagi total produksi dan total penggunaan suatu faktor produksi. Jika faktor produksi yang digunakan lebih dari satu jenis, maka konsep produktivitas yang lebih banyak digunakan adalah produktivitas faktor total (Maulana, 2004).…”

Research on productivity and technical efficiency of lowland organic rice was conducted in Sukorejo and Jambeyan villages, Sambirejo District, Sragen Regency. The research applies interview techniques to obtain primary data from 120 respondents. The respondents are selected using non proportionate stratified random sampling technique which is divided into equal size of four levels. This research aims to analyze the productivity, technical efficiency and source of technical inefficiency of organic rice, and compare the results with conventional rice performance. Productivity is measured by total factor productivity approach applies TFP index value. Technical efficiency is measured by using frontier production function and is estimated using MLE method assuming that Cobb-Douglas is the functional form of farm organic rice in the research areas. Estimation source of technical inefficiency applies linear regression model that approach simultaneously using frontier production function. The research result indicates that organic rice farmer's performance of the eighth year and the fifth year is more productive than the conventional rice farmers. The level of technical efficiency varies from 0.47 to 0.96 with the average of 0.70. The level of technical efficiency of organic rice farmers of the eighth year and the fifth year is higher significantly compared to the conventional rice farmers. The result also shows that the number of productive age of family members and the frequency to attend extension activities is influencing to reduce technical inefficiency.Key words: productivity, technical efficiency, technical inefficiency, organic rice ABSTRAK Penelitian produktivitas dan efisiensi teknis usahatani padi organik lahan sawah dilakukan di Desa Sukorejo dan Jambeyan, Kecamatan Sambirejo, Kabupaten Sragen menggunakan responden sebanyak 120 orang yang dipilih dengan teknik non proportionate stratified random sampling yang terbagi sama besar dalam empat strata. Penelitian ini bertujuan untuk menganalisis produktivitas, efisiensi teknis dan sumber inefisiensi teknis padi organik, serta membandingkan dengan padi konvensional. Produktivitas diukur dengan pendekatan produktivitas faktor total menggunakan angka indeks TFP. Efisiensi teknis diukur dengan menggunakan fungsi produksi frontier yang diestimasi dengan metode MLE, dengan mengasumsikan Cobb-Douglas adalah bentuk fungsional usahatani padi organik di daerah penelitian. Estimasi sumber inefisiensi teknis menggunakan model regresi linier yang diestimasi secara simultan dengan fungsi produksi frontier. Hasil Penelitian menunjukkan bahwa petani padi organik tahun ke-8

“…Considering the extent of the contribution of technology (rice productivity) to the rice supply, there should be efforts to develop the rice production technology which leads to the increase of rice production through various intensification programs. A similar opinion is stated by Maulana (2004), who argues that to incease crop productivity the development of agricultural technology has a very strategic role. The increase of rice productivity is agronomically caused by two factors, namely the use of rice varieties with high productivity and the improvement of rice cultivation management.…”

This research aimed at examining: (1) rice supply adjustment for the long-term equilibrium (2) the impact of the government's policies on rice grain purchasing price to the rice supply, (3) and factors influencing the long-term and short-term rice supply in the rice-producing regions in Indonesia. This research used the panel data regression with the error correction model approach. The data were the yearly time series data of 1987 through 2008. The results showed that (1) the rice supply adjustment for the long-term equilibrium was at 68%, (2) in the long term, the government's policies on rice grain purchasing price reduced the rice supply, (3) in the long term, the rice retail price, the rain fall, and the technology had a positive influence on the rice supply, while the cassava and soybean prices had a negative influence. In the short term, the rice retail price and technology had a positive influence, while the cassava and soybean prices and the monetary crisis dummy had a negative influence to the rice supply in the rice-producing regions in Indonesia.

“…Menurut Martinez-Cordero et al (1999) TFP merupakan ukuran kemampuan seluruh jenis faktor produksi sebagai satu kesatuan faktor produksi agregat dalam menghasilkan output keseluruhan. Otsuka (1988) dalam Maulana (2004) mendefinisikan TFP sebagai rasio indeks hasil produksi dengan indeks total faktor produksi.…”

Kuantitas produksi udang tambak Indonesia meningkat signifikan dalam dua dekade terakhir, dari 97,2 ribu ton tahun 1989 menjadi 352 ribu ton tahun 2010, dengan puncaknya 409 ribu ton pada tahun 2008. Studi ini bertujuan untuk menganalisis kinerja produktivitas tambak udang dan mengetahui faktor-faktor yang mempengaruhi TFP menggunakan pendekatan angka Indeks Tornqvist Theil. Hasil studi menunjukkan bahwa pertumbuhan udang tambak Indonesia periode 1989-2008 lebih karena pertumbuhan input/faktor produksi bukan karena pertumbuhan TFP. TFP berfluktuasi disebabkan belum berhasil diatasinya permasalahan penyakit. Hasil konfirmasi pada tingkat lapang menggunakan data primer dari 163 petak tambak menunjukkan bahwa serangan penyakit berpengaruh negatif dan signifikan terhadap TFP. Intensifikasi, benur bersertifkat, dan lamanya pendidikan berkorelasi positif, akan tetapi kondisi riil Indonesia berbeda yaitu mayoritas tambak dikelola secara non intensif. Studi ini juga menunjukkan bahwa luas pengusahaan dan sistem kerjasama antara pembudidaya dengan lembaga pemasaran lainnya berpengaruh negatif terhadap TFP. Terkait dengan hal itu, pemerintah perlu memprioritaskan meningkatkan produktivitas dengan mengatasi serangan penyakit melalui penambahan anggaran riset bidang penyakit, penyediaan benur bermutu, peningkatan sumber daya manusia (SDM). Selain itu, diperlukan regulasi dalam hal pengaturan pola tanam dengan penggantian species yang dapat memutus rantai penyakit. Disamping itu, direkomendasikan agar mengurangi padat penebaran. Tittle: Productivity Performance and Factors Influencing to the Total Factor Productivity (TFP) of Indonesia Shrimp Cultured.Production of Indonesian shrimp cultured has experienced a remendeous growth during the last two decades with its peak performance at 409 metric tons in the year of 2008. The objective of this research was to analyze productivity performance of Indonesian shrimp cultured using the Tornqvist Theil Index and its determinants. Results showed that source of growth was mainly due to input gowth. TFP fluctuations were mainly because of disease outbreaks. Using field data comprises a total of 163 ponds confirm that disease outbreaks plays an important role in lowering TFP. Intensification, fry certification, and education halved a positive correlation with TFP. However, the Indonesian shrimp farmers in majority cultured the shrimps using traditional system. On the other hand, cooperation between farmers and other marketing institution and total pond area show a negative effects on achieving higher TFP. Therefore, the government could improve farmed shrimp productivity through increasing research budget on diseases, improving seed quality and human resources. The government should also put a priority regulation on changing cropping system accompanied by changing shrimp species cultured so that carrier agents of diseases can be broken. Apart from these, lowering stocking density was also suggested.
