Abstract

Boiler ash is a solid waste from biomass combustion from palm oil mills. The boiler ash can be used as fertilizer because it has a high content in the samples of N, P, K and Mg and is safe for the environment. This study aims to determine the effect of boiler ash fertilizer on the growth of cocoa seedlings and get the optimal fertilizer dose when applied. This research was conducted in Jayapura – Papua for 3 months (September – November). This study used a completely randomized design that was repeated as many as 6 replications. The treatments given include: A0 (control), A1 (300 g.polybag–1), A2 (350 g.polybag–1), A3 (400 g.polybag–1) and A4 (450 g.polybag–1). Parameters measured were plant height, leaf number, leaf width, leaf length and plant wet weight. Based on statistical tests, the results showed that the use of boiler ash fertilizer on the growth of cocoa seedlings which was seen from all parameters had no significant effect. However, A4 treatment using 450 g of boiler ash fertilizer per polybag gives significant results for all parameters measured.

Abstract

Buah kelapa hutan dimanfaatkan oleh masyarakat Pegunungan Tengah Papua sebagai makanan lokal khususnya ketika pada saat kekurangan makanan. Secara tradisional masyarakat setempat mengonsumsi buah kelapa hutan dengan cara dimakan mentah atau diolah lebih lanjut dengan cara dibakar dan diasapi. Metode penelitian yang digunakan adalah uji kualitatif dengan pengujian laboratorium menggunakan gas chromatografi untuk mengidentifikasi profil asam lemak dari ekstraksi kelapa hutan mentah dan hasil olahan dengan cara dibakar. Selanjutnya hasil yang diperoleh, dianalisis secara deskriptif untuk melihat profil asam lemak dari ekstraksi buah kelapa hutan mentah dan hasil olahan dengan cara dibakar. Hasil penelitian ini menunjukkan bahwa tepung buah kelapa hutan mentah dan tepung buah kelapa hutan hasil olahan dengan dibakar memberikan hasil profil asam lemak (asam lemak jenuh dan tidak jenuh) yang tidak berbeda signifikan. Sebanyak 6 asam lemak yang teridentifikasi pada tepung buah kelapa hutan mentah yaitu asam palmitat 41,25%, asam stearat 2,66%, asam oleat (omega 9) 24,12%, asam linoleat (omega 6) 27,91%, asam linolenat (omega 3) 0,18% dan asam arakhidat 0,24 %. Sedangkan pada tepung buah kelapa hutan hasil olahan dengan dibakar, teridentifikasi sebanyak 6 asam lemak yaitu asam miristat 0,25%, asam palmitat 60,96%, asam palmitoleat 0,26%, asam linoleat (omega 6) 37,38%, asam linolenat (omega 3) 0,33% dan asam arakhidat 0,21%.

Abstract

Post-harvest oil palm that does not comply with the Factory standart can cause losses in reducing the production of fresh fruit bunches. The objectives of this study are 1) To analyze he stages of harvest and the sources that result in the risk of harvesting oil palm FFB in each post-harvest chain that is traversed to the TPH at the Koperasi Petani Sawit Mandiri (KOPSA-M), Pangkalan Baru Village, Kampar Regency. 2) To analyze the amount of yield loss and the possible risk of harvesting oil palm FFB in each post-harvest chain That is traversed from the land to the TPH at the Koperasi Petani Sawit Mandiri (KOPSA-M) Pangkalan Baru Village, Siak Hulu District, Kampar Regency. The data analysis was descriptive quantitative research analysis. Sources of loss post-harvest of oil palm FFB at the Pangkalan Baru Village Independent Farmers Cooperative (KOPSA-M), Siak Hulu sub-district, Kampar district is the percentage of post-harvest loss of fresh fruit bunches (FFB). is equal to 5.21 percent of the total average FFB produced per plot (2 hectares). the losses are in the land, TPH, checking raw FFB and mill sorting. The percentage of losses in the land area is 1.73 percent of the total FFB yield. Meanwhile, the number of losses in the factory sorted amount was 2.70 percent and became the most significant loss for post-harvest FFB losses at KOPSA-M. The sources of post-harvest loss of FFB at KOPSA-M are harvest time, harvesting techniques. implemented by harvesters, cleanliness of plantation land, harvesting places (TPH), fruit and plant maintainers, and sunlight, human resources (HR) from oil palm harvesters,
