Abstract

Oil palm has the prospect of rapid development in Indonesia, which causes an increase in plantation area to continue. However, the problem that is still encountered is the low productivity and quality of crop production. The solution that can be used is the use of planting material derived from superior varieties. High-yielding varieties are assembled through hybridization of two varieties that have the desired superior properties. Observation of the flower development cycle is needed as the basis for the hybridization process. Flower development is not only influenced by genetic factors, but also by environmental factors, especially climate. Observations on plant responses are part of a phenological study. This research was carried out in April-August 2021 at Pabatu Gardens, PTPN IV with the aim of observing the flowering phenology of the DxP 540 NG and DxP Socfindo MT Gano varieties. The climatic conditions of the research location during the observation were an average temperature of 29°C, 80% humidity, and an average rainfall of 145 mm/month. The average time required for the DxP 540 NG variety of male and female flowers, the growth phase of the sheath until the outer sheath broke, was 40 days and 38 days, the outer sheath broke until the inner sheath burst was 15 days and 18 days, the inner sheath broke to full bloom was 12 days. days and 16 days, and in full bloom until the flowers are completely pollinated, namely 4 days and 6 days. The average time required for the DxP 540 NG variety of male and female flowers in the growth phase of the sheath until the outer sheath breaks are 32 days and 30 days, the outer sheath breaks until the inner sheath bursts are 16 days and 15 days, the inner sheath bursts to full bloom, namely 11 days and 15 days, and in full bloom until the flowers are perfectly pollinated, namely 4 days and 6 days. The total time required for flowering for the male and female DxP 540 NG varieties was 71 days and 78 days, while for the DxP Socfindo MT Gano variety, male and female flowers were 63 days and 66 days, respectively.

Abstract

Plantation of PT. Tidar Kerinci Agung (PT. TKA) is a company engaged in oil palm plantations with an area of 24,000 ha and has been certified by Indonesia Sustainable Palm Oil (ISPO). PT. TKA has a factory for Crude Palm Oil (CPO) processing, therefore the local community can sell their palm oil yield to the factory. However, the purchase of Fresh Fruit Bunches (FFB) from the community was constrained by the fact that many people use random seeds which reduce the quality of CPO, moreover the agronomic factors such as fertilization, rainfall, plant maintenance and harvesting on smallholder plantations which are the factors that can reduce the quality of CPO. The present study was conducted for 3 months, with the objective was to determine the comparison of the palm oil extraction rate between smallholder plantations and large-scale estate (PT. Tidar Kerinci Agung). The research method was a survey by purposive sampling to obtained data on oil palm production, especially in relation with oil extraction rate. The result showed that the oil extraction rate of CPO was 24.51% and it’s on Palm Kernel Oil (PKO) was 4.45% in large-scale estate (PT. TKA). It was higher than the oil extraction rate on smallholder plantations. The oil extraction rate of CPO and PKO in the high yielding, moderate yielding, and low-yielding smallholder plantations were CPO 20.55% and PKO 4.42%, CPO 21.50% and PKO 3.77%, and CPO 18.35% and PKO 4.34%, respectively.

Abstract

Gambir (Uncaria gambir Roxb.) sebagai komoditi unggulan di Sumatera Barat, yang dalam produksi dan pengolahannya menghasilkan limbah berupa ampas kempaan daun gambir. Pengomposan limbah pertanian pada umumnya berlangsung lama tanpa pemberian bioakivator, karena bioaktivator dapat mempercepat dekomposisi. Tujuan dari penelitian ini adalah untuk mendapatkan jenis bioaktivator yang paling efektif dalam pengomposan ampas kempaan daun gambir (U. gambir Roxb.). Penelitian dilaksanakan selama 4 bulan di lahan percobaan Kampus III Universitas Andalas yang berlokasi di Sungai Kambut, Pulau Punjung, Dharmasraya, Sumatera Barat. Sedangkan ampas kempaan daun gambir didapatkan di Gunuang Malintang, Pangkalan Koto Baru, Kabupaten Lima Puluh Kota, Sumatera Barat. Perlakuan yang diberikan yaitu kontrol (tanpa bioaktivator), bioaktivator Stardec (10 g/kantong), bioaktivator Trichoderma harzianum (8 g/kantong), dan bioaktivator Effective Microorganism 4/EM4 (5 ml/kantong). Parameter pengamatan pada kompos yakni tekstur, warna, suhu, pH, kadar air, C-organik N, P, K, dan rasio C/N. Analisis data dilakukan dengan sidik ragam (uji F) pada taraf 5% dan dilanjutkan dengan Duncan’s New Multiple Range Test (DNMRT) pada taraf 5%. Selanjutnya, dilakukan pengujian nilai relativitas agronomi (relative agronomic effectiveness/RAE). Efektivitas bioaktivator Stardec, T. harzianum, dan EM4 memberikan pengaruh terhadap pengomposan ampas kempaan daun gambir. Effective Microorganism 4 (EM4) merupakan bioaktivator yang paling efektif dalam pengomposan ampas kempaan daun gambir berdasarkan nilai RAE.
