Kabupaten Parigi Moutong merupakan salah satu wilayah penghasil beras yang cukup besar di Sulawesi Tengah yang diharapkan dapat menjadi sumber pertumbuhan baru produksi beras Nasional di Indonesia. Pemerintah Daerah menetapkan wilayah ini, sebagai daerah penyangga beras terbesar di Sulawesi Tengah. Tujuan dari Penelitian ini adalah untuk : 1. Mengidentifikasi berbagai permasalahan dan tingkat penerapan inovasi teknologi pertanian di Kabupaten Parigi Moutong dan 2. Menetapkan arahan dan alternatif teknologi yang potensial untuk pengembangan lahan di Kabupaten Parigi Moutong. Penelitian ini dilaksanakan sebanyak dua tahap yaitu tahap 1 Desk study dan 2. Penelitian Lapangan. Desk study dilakukan dengan cara penelusuran pustaka dan diskusi dengan stake holders lainnya. Untuk Penelitian lapangan dilaksanakan dengan menggunakan metode survey dengan melakukan pengamatan kondisi sosial ekonomi dan budaya serta pengamatan tingkat penerapan inovasi teknologi melalui pendekatan Partisifatif Rural Aprasial atau Pengenalan Desa Secara Partisifatif (PRA). Pelaksanaan penelitian dilakukan selama 2 bulan yaitu dari bulan Juni hingga bulan Juli 2014. Hasil penelitian menunjukkan bahwa terdapat potensi perluasan areal persawahan dan peningkatan luas tanam karena didukung oleh iklim dan irigasi yang cukup baik. Tingkat penerapan teknologi masih cukup rendah terutama penggunaan varietas unggul, benih unggul dan bermutu serta pemupukan. The achievement level of self-sufficiency and food security, particularly in rice production should be supported by natural resources and the application of technology innovation. Parigi Moutong Regency is one of the largest rice producer areas in Central Sulawesi, which is expected to be a new growth source area of national rice production in Indonesia. Local government has set this region as the largest rice buffer zone in Central Sulawesi. The aim of this study was to: 1) Identify the problems and the application level of agricultural technology innovation in Parigi Moutong Regency and 2) Setting the direction and potential of alternative technologies for the development of rice land area in the Regency of Parigi Moutong. This research had two steps, namely : 1) desk study and 2) field research. Field research method was done using a survey method of observing socio-economic and cultural conditions as well as the observation of the level of technology innovation through Participative Rural Appraisal (PRA) approach or partisipative village introduction. The research was conducted from June to July 2014. The result shows that there is a potential for expansion and improvement of rice cultivation acreage because it is supported by the suitable climate condition and well-managed irrigation facilities. However, the level of technology application is still relatively low, especially in the use of improved varieties, improved and quality seed and also proper fertilization.

Lili (Lilium sp.) termasuk famili Liliaceae, merupakan tanaman hias yang memiliki nilai ekonomi tinggi karena permintaan konsumen terus meningkat. Permintaan varietas tanaman yang seragam menuntut pengembangan hibrida F1. Perakitan tanaman hibrida dapat dihasilkan melalui pembentukan tanaman haploid. Salah satu metode untuk memproduksi tanaman haploid adalah dengan kultur antera. Pengecekan tanaman hasil kultur antera dapat dilakukan dengan penghitungan jumlah kloroplas dan jumlah kromosom, namun untuk lili hasil belum diperoleh informasi mengenai korelasi antara jumlah kloroplas pada sel penjaga stomata dengan jumlah kromosom, sehingga tujuan penelitian ini adalah untuk mengatahui korelasi antara jumlah kloroplas dengan jumlah kromosom serta mengetahui tingkat ploidi pada regeneran lili hasil kultur antera. Penelitian ini dilaksanakan di Laboratorium Kultur Jaringan Balai Penelitian Tanaman Hias (BALITHI) Cianjur dari Januari-Juni 2016. Terdapat 5 nomor lili yang diuji tingkat ploidinya. Setiap nomor terdiri dari 4 ulangan, setiap ulangan ada 4 botol dan masing-masing botol terdiri dari 3 planlet. Metode analisis yang digunakan yaitu statistik sederhana rata-rata dan standar eror dan dikorelasikan. Hasil penelitian menunjukkan planlet haploid terbanyak ditemukan pada nomor 2015.1.1 kelompok Longiflorum dengan jumlah 26,67% sedangkan planlet haploid yang jumlahnya paling sedikit ditemukan pada nomor 2015.S2.3 kelompok Oriental dengan jumlah 11,11%. Metode kultur antera dapat menghasilkan planlet haploid namun pada Lilium sp. persentase keberhasilannya masih rendah. Tidak diperoleh korelasi antara jumlah kloroplas dan kromosom. Penelitian lebih lanjut terkait tingkat ploidi tanaman lili dan pengujian jumlah kromosom dengan menggunakan flowcytometer perlu dilakukan. Lily (Lilium sp.), Liliaceae family, is an ornamental plant that has a high economic value as consumer demand continues to rise. The uniformity of crop varieties requires the development of F1 hybrids that can be generated through the formation of haploid plants. A method for producing haploid plant is by anther culture. Evaluation of anther culture can be done by counting the number of chloroplasts and the number of chromosomes in the regenerants. However, lilies yet obtained information on the correlation between the numbers of chloroplasts in stomatal guard cells with chromosome numbers. Therefore, the purpose of this research aimed to know the correlation between the number of chloroplasts and chromosomes and to determine ploidy level in the regenerants of lily from anther culture. This research was conducted at Tissue Culture Laboratory of Indonesian Ornamental Crops Research Institute (IOCRI), Cianjur from January to June 2016. There were 5 numbers of lilies regenerant from anther culture that evaluate for ploidy level test. Each number has four replications, each replication contained four bottles, and each bottle has three plantlets. The statistical analysis used statistical descriptive with average, standard error and correlation. The results showed, haploid plantlets were observed in 2015.1.1 plantlets from Longiflorum group with 26,67% while least number of haploid plantlets is found in 2015.S2.3 plantlets from Oriental group (11,11%). The method of anther culture is able to produce haploid plantlets but the success rate was low in Lilium sp. There were no correlation between the number of chloroplasts and chromosomes. Further studies related to the ploidy level of lilies from anther culture and the evaluation of chromosomes number by using flow cytometry requires to develop haploid plant of Lily.
