Abstract

Melada (Piper colubrinum Link.) termasuk tumbuhan liar yang tidak dibudidayakan untuk tujuan khusus. Melada ini tahan terhadap serangan penyakit busuk batang sehingga digunakan untuk batang bawah pada penyambungan lada. Untuk mendapatkan batang bawah yang bagus perlu pemeliharaan yang baik seperti pemupukan, sehingga dapat mendukung pertumbuhannya. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk NPK terhadap pertumbuhan bibit tanaman melada dan mendapatkan dosis optimum pupuk NPK. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Tanjungpura, berlangsung dari tanggal 14 Juli-4 Oktober 2023. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap faktor tunggal dengan 5 perlakuan dan setiap percobaan diulang 4 kali. Perlakuan dosis pupuk NPK terdiri atas empat   taraf, yaitu : pupuk NPK 0 gram/tanaman, pupuk NPK 6 gram/tanaman, pupuk NPK 9 gram/tanaman, pupuk NPK 12 gram/tanaman, dan pupuk NPK 15 gram/tanaman. Variabel yang diamati dalam penelitian ini adalah pertambahan tinggi tanaman, pertambahan jumlah daun, pertambahan diameter batang, indeks warna daun, panjang daun, dan lebar daun. Hasil penelitian menunjukkan bahwa pemberian beberapa dosis pupuk NPK yang berbeda memberikan pengaruh terhadap pertambahan tinggi, panjang daun, dan lebar daun melada. Penambahan dosis tidak serta merta meningkatkan pertumbuhan. Pemberian pupuk NPK dosis 6 g/tanaman menunjukkaan dosis optimum untuk bibit melada.

Abstract

Performance Study of Independent Small Holder Oil Palm Plantation at Kubu Raya Regency. Independent small holder oil palm plantations are small holder oil palm plantations that are not affiliated with any institution. Farmers sell their own produce to local mills directly or through traders. Independent oil palm smallholders are faced with various problems, including limited access to information technology sources, financing, and markets. Independent small holder oil palm plantations in Kubu Raya Regency are facing a bigger problem because most of the plantations are on peatlands, therefore efforts are needed to help these farmers. Efforts that need to be made at this time are the provision of a database of independent small holder oil palm plantations, which so far do not exist. This study aims to obtain data on the performance of independent small holder oil palm plantations in Kubu Raya Regency. Collecting data using the interview method with a questionnaire. The results showed that most of the independent small holder oil palm farmers in Kubu Raya Regency running their business only as a side job so that the management is not optimal. Another obstacle is the difficulty in accessing the market so they are forced to sell their fruit through middlemen. The problem of transportation, namely transportation and inadequate roads, is also one of the causes of the difficulty in marketing the fresh fruit bunch.

Abstract

Forest conversion activities into non forestry purposes impacts on decreasing of forestfunction as a main role sustainable development, especially as water regulators and as carbon storage. Therefore, deforestation not only causes a direct loss of forest habitat but also leads to indirect impacts as ecosystem services deteriorate or fail. Forests provide ecosystem services that include the regulation of weather and climate at local, regional and even global levels. Existence of protected forest Pinang Luar ± 3.228 acres take an important part and people living in the area has a high dependency on the forest. Farming activities become a treat to the forest and their indications show that cropland and palm estate already in the forest area. Land cover changes in protected forest Pinang luar at 2003 – 2012 impacts on villages at ring 1 area hierarchy decrease cause by population growth are not followed by the additional of infrastructures in economy, health and education. It is also caused by landconversion that occurred in the protected forest Pinang Luar. In the period 2003 - 2012, the villages directly affected (ring 1) have a level area hierarchy is much worse compared to villages that are not directly affected (Ring 2). And it affected to the development of the villages in the ring 2 which is better than the village at ring 1. These conditions happen because at the village in ring 1 change only on land not on the impact on the level of development that could affect the region hierarchy. This is in contrast with the ring 2 villages where the changes occur not only on land but also on its impact on the development so as to enhance the region hierarchy in ring 2 villages.
