The current practice in determining oil palm fresh fruit bunches (FFB) ripeness is by its colour which could be inaccurate. This study investigates the classification of oil palm FFB ripeness using Raman spectroscopy. A feature extraction model is developed based on the different organic compositions that contribute to the ripeness classification. Samples are collected according to the Malaysian Palm Oil Board (MPOB) standards which are unripe, underripe, ripe, overripe, and rotten. Different characteristics of the Raman shift were detected which represent the material composition for each sample. The Raman intensity of the oil palm fruit increases from unripe to ripe before decreasing to rotten due to the carotenoid content in the fruit. In conclusion, Raman spectroscopy is a suitable technique to observe the changes in the composition of oil palm fruit classified by its ripeness.

Pengelolaan perkebunan kelapa sawit sering mengalami kendala, antara lain masalah organisme pengganggu tumbuhan (OPT) terutama masalah penyakit. Oleh karena itu, dibuatlah pendekatan untuk mengenali penyakit pada daun kelapa sawit agar dapat membantu kinerja dari para petani kelapa sawit dalam menentukan jenis penyakit pada daun sehingga mendapatkan hasil yang lebih maksimal. Deteksi tepi adalah perubahan nilai intensitas derajat keabuan yang mendadak (besar) dalam jarak yang singkat. Sobel operator digunakan untuk pengidentifikasikan pola wajah, khususnya terdapat di dalam algoritma deteksi tepi. Support Vector Machine (SVM) digunakan sebagai metode klasifikasi. Oleh karena itu, dalam penelitian ini penulis akan menerapkan metode deteksi tepi dengan menggabungkan teknik algoritma Sobel Operator untuk menghilangkan derau dan metode Support Vector Machine sebagai pengklasifikasian data penyakit pada daun kelapa sawit. The management of oil palm plantations often experiences obstacles, including problems with plant pest organisms (OPT), especially disease problems. Therefore, an approach was made to encourage the disease in the leaves of oil palm so that it can help the performance of oil palm farmers in determining the type of disease in the leaves so as to get maximum results. Edge detection is a change in the value of the sudden intensity of the degree of gray (large) in a short distance. Sobel operators are used to identifying face patterns, especially those found in edge detection algorithms. Support Vector Machine (SVM) is used as a classification method. Therefore in this study, the author will apply the edge detection method by combining the Sobel Operator algorithm technique to eliminate noise and the Support Vector Machine method as a classification of disease data on palm oil leaves.

The purposes of this study were to know marketing channel, marketing margin, share, and marketing profit of fresh fruit bunches of oil palm in Tempakan Village, Batu Engau Subregency, Paser Regency. The study was conducted from June to August 2016. The sampling method was done with two ways as random sampling in farmer level and in marketing channel as snowball sampling. Data analysis were done by calculating marketing margin, share, and marketing profit. The results of this study showed that there are two marketing channels in reserach location are channel of level zero and channel of level one. Marketing margin in farmer level was Rp40.39 kg-1 and margin in whole trader level was Rp314.44 kg-1. The average share of farmer level was 97.58% and in trader level was 81.48%. Margin and share that profitable for farmer is at channel of level zero. The average of profit in whole trader level of fresh fruit bunches was 112.75%, that meant marketing by whole trader is profitable.
