===Background===
+
===Latar belakang===
−
For keeping track of management and yield it is useful to have a good map of the plantation on which all palms are indicated. On this map, ''dura'' and ''pisifera'' palms and empty spots should also be marked. In addition, for pest patrols and leaf sample collection it is necessary to select and mark ‘sample palms’, because it is too much work to check or sample all palms. It takes some time to map the field and mark the sample palms, but in the end it will save a lot of time – even if no leaf sampling is done.

Plantation maps are usually drawn on isometric paper (see [http://akvopedia.org/wiki/File:Oil-palm-4.14-figure27.png Figure 27]). Each palm should be indicated with a dot on the intersection of two lines (see [http://akvopedia.org/wiki/File:Oil-palm-4.14-figure28.png Figure 28]). If there is no palm, put a cross or leave the spot empty.
+
Peta perkebunan biasanya digambar pada kertas isometrik (lihat [[akvopedia:File:Oil-palm-4.14-figure27.png|Gambar 27]]). Setiap sawit harus digambarkan sebagai titik pada simpangan dua garis (lihat [[akvopedia:File:Oil-palm-4.14-figure28.png|Gambar 28]]). Jika tidak ada penanaman sawit di lokasi itu, beri silang atau kosongi saja.
  
−
'''Note''': If the field is not rectangular, drawing it can be more difficult. Isometric paper will only work when the palms are planted in the correct (triangular) spacing. For rectangular (square) spacing, use simple mathematical paper with squares. For other spacing, draw the plantation on white paper without lines.   
+
'''Catatan''': Jika lahan tidak berbentuk persegi panjang, penggambarannya akan lebih sulit. Kertas isometrik hanya bisa digunakan ketika sawit ditanam di ruang (segitiga) yang tepat. Untuk ruang persegi (bujursangkar), gunakan kertas matematis sederhana yang menggunakan rentetan bujursangkar. Untuk bentuk ruang lainnya, gambar peta perkebunan pada kertas kosong tanpa garis.

Latar belakang

Untuk memastikan keberlangsungan manajemen dan hasil panen yang stabil, maka perlu dibuatkan pemetaan perkebunan yang menunjukkan sawit mana saja yang terindikasi. Pada pemetaan ini, sawit dura dan pisifera dan lahan kosong juga perlu ditandai. Dengan ini, penting pula untuk memilih dan menandai 'sampel sawit’ untuk pengawasan hama dan koleksi sampel pelepah, karena akan sangat menguras kinerja jika harus memeriksa atau mengambil sampel dari semua sawit yang ada. Memang butuh waktu untuk melakukan pemetaan dan menandai sampel sawit, namun pada akhirnya hal ini akan menghemat waktu kerja – meskipun proses sampling pelepah belum pernah dikerjakan.

Tujuan

  • Agar dapat memantau efisiensi manajemen dan produktivitas;
  • Agar dapat secara efektif menjalankan proses patroli hama;
  • Agar dapat secara efisien menjalankan proses sampling pelepah.

Standarisasi

  • Menyediakan pemetaan perkebunan secara lengkap, yang menunjukkan posisi sawit, lahan kosong, dan batas-batas perkebunan;
  • Pemilihan sampel sawit antara 1-4 persen dari seluruh populasi sawit di perkebunan;
  • Sampel sawit sehat dan merupakan representasi dari perkebunan;
  • Sampel sawit tersebar secara merata di seluruh areal perkebunan;
  • Sampel sawit ditandai dengan jelas.

Waktu pelaksanaan

  • Sekali, pada awal proses rehabilitasi.

Frekuensi

  • Sekali sepanjang waktu efektif perkebunan.

Catatan: Setiap kali melakukan proses sampling (atau jika dilakuan sekali dalam setiap tahun) periksa kembali sampel sawitnya apakah masih dalam kondisi sehat dan penandanya masih jelas. Jika tidak, pilih sawit lainnya dan/atau ulang kembali penanda sawitnya.

Kebutuhan waktu tenaga kerja

  • Menggambar peta perkebunan: 2-3 jam untuk lahan seluas 2 hektar.
  • Menandai sampel sawit: 1-2 jam per 2 hektar.

  • Sebaiknya dikerjakan bersama dengan penyuluh atau perwakilan dari kemitraan.

Cara pelaksanaan

Menggambar peta perkebunan

Peta perkebunan biasanya digambar pada kertas isometrik (lihat Gambar 27). Setiap sawit harus digambarkan sebagai titik pada simpangan dua garis (lihat Gambar 28). Jika tidak ada penanaman sawit di lokasi itu, beri silang atau kosongi saja.

Catatan: Jika lahan tidak berbentuk persegi panjang, penggambarannya akan lebih sulit. Kertas isometrik hanya bisa digunakan ketika sawit ditanam di ruang (segitiga) yang tepat. Untuk ruang persegi (bujursangkar), gunakan kertas matematis sederhana yang menggunakan rentetan bujursangkar. Untuk bentuk ruang lainnya, gambar peta perkebunan pada kertas kosong tanpa garis.

Untuk menggambar peta perkebunan, gunakan langkah-langkah berikut:

Langkah 1. Select the first field to be mapped.
Langkah 2. Determine the boundaries of the field (e.g. roads, other crops, rivers/streams, oil palm from someone else etc.).
Langkah 3. Determine the direction of the palm rows:
  • If the palms are planted in the correct (triangular) format, the rows can be seen in two directions.
  • Selecting palms is easier when the directions are in line with the field borders.

If the field is not rectangular, try to find the direction of the rows which makes them most easy to count.

Langkah 4. Draw the palms next to the main road into the map and count the number of rows.
Langkah 5. For each row, draw in the palms and count the number of palms per row.
Langkah 6. Indicate streams, rivers, roads and other borders, trying to keep the size correct. Note: Usually a road is one palm row wide (sometimes two).

Selecting and marking sample palms

To select and mark sample palms follow these steps:

Step 1. Select which road will be the main road.
Step 2. Starting in one corner and moving along the road count five rows. At the 5th row:
  • Stand on the side of the palm facing the road;
  • Find a frond butt which has some flat area to write on;
  • Paint the frond butt with white paint;
  • When the paint is dry, write the row number at the top with blue paint (in this case: ‘5’);
  • Below the row number, write the palm number with blue paint (in this case: ‘1’).

Note: all palm numbers at the roadside should be ‘1’.

Step 3. Find the direction of the row and follow the row from palm to palm until you get to palm 5. Note: Empty spots also count.
Step 4. At palm 5, check the following:
  • Is the palm present?
  • Does the palm look healthy?
  • Is the palm more or less as tall as its neighbours?
  • Is the palm in a representative location (for example not in a piece of swamp or on the very edge of a gully)?
  • Are all the palms around that palm present (no empty spots)?
Step 5. If the answer to one of the questions is ‘no’, move two palms further into the row and check again.
Step 6. If the answer to all the questions is ‘yes’, mark that palm as described above (in this case: ‘5 over 5’) (see Figure 29).
Step 7. Continue along the row, each time marking the 5th palm (or two palms farther along if the 5th palm doesn’t meet the conditions) until you are two palms from the other end of the field. The palms that are close to the edge of the field (one or two palms away) should not be sampled, because they are not representative (for example, they get more sunlight).
Step 8. Move on to the field boundary
Step 9. Move five rows further along the boundary at the other end. After 5 rows, mark the palm next to the boundary. This should be the 10th row after the start of the field, so the row number on this palm should be 10. The palm number is the number of the last palm in the row.

Note: If the field is not rectangular, it may be necessary to walk back to the beginning of the row and count the number of palms to determine the palm number.

Step 10. Move into the field and repeat step 8–13.
Step 11. Continue until the entire field is done.

Note: The number of the palms to mark depends on the size of the field. In large fields (5–10 ha) it is better to take every 8th row and every 8th palm. In even larger fields (more than 10 ha) you can take every 10th row and every 10th palms. This is also what companies do.

If the field is not at all rectangular, try to select the palms as follows:

  • One palm in 25 (or in 64 or 100 in larger plantations);
  • Not the palms less than 2 lines from the boundary;
  • At least 4 non-sample palms between the sample palms in each direction.
