Planting media in oil palm nurseries generally consists of soil mixed with sand and inorganic fertilizers such as phosphate fertilizers. Organic matter is often used to further increase the productivity of the growing media. The purpose of the study was to determine the effect of oil palm midrib biochar and the administration of phosphate fertilizer doses on the growth of pre-nursery oil palm. The research was carried out at the Biochar Research Station and Laboratory of Seed Science and Technology, Faculty of Agriculture, Universitas Syiah Kuala, Darussalam, Banda Aceh. This study used a 3 x 4 factorial randomized block design with 3 replications, so there were 12 treatment combinations and 36 experimental units. The results showed that the biochar treatment was very significant on soil pH and not significant on stem diameter, plant wet and wet weight of oil palm roots, the best dose of oil palm frond biochar was found in 14 g polybag-1.

The results showed that the application of n-hexane nut extract had a very significant effect on weed height, stem diameter, number of leaves, ","PeriodicalId":17799,"journal":{"name":"Jurnal Ilmiah Mahasiswa Pertanian","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86319164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salah satu indikator yang sangat menentukan mutu, kualitas dan harga minyak nilam yaitu kadar patchouli alcohol. Semakin tinggi kadar patchouli alcohol dalam minyak nilam, maka mutu minyak nilam akan semakin baik. Pembuatan bahan standar patchouli alcohol yang terkandung dalam minyak nilam dapat dilakukan dengan cara mengisolasi patchouli alcohol. Salah satu metode yang digunakan adalah dengan distilasi fraksinasi. Proses fraksinasi adalah proses pemurnian zat/senyawa yang digunakan untuk memisahkan komponen dari campuran berdasarkan suhu titik didih. Proses distilasi fraksinasi nilam dapat dilakukan dengan alat rotary vacuum evaporator. Berdasarkan kadar patchouli alcohol, hasil dari distilasi fraksinasi minyak nilam dibedakan menjadi fraksi berat dan fraksi ringan. Tujuan dari penelitian ini adalah untuk mengetahui kualitas minyak nilam Aceh Selatan sebelum dan sesudah dilakukan pemurnian menggunakan rotary vacuum evaporator. Penelitian ini dilakukan dengan analisis eksperimental. Parameter yang diamati pada penelitian ini meliputi kualitas minyak nilam yaitu warna minyak, bobot jenis, indeks bias, kelarutan dalam etanol, bilangan asam, bilangan ester, putaran optik, patchouli alcohol dan kadar besi (Fe). Hasil penelitian menunjukkan bahwa secara keseluruhan kualitas minyak nilam sebelum dimurnikan sudah sesuai standar SNI, namun untuk kadar patchouli alcohol masih sangat rendah dan tidak sesuai dengan SNI. Proses pemurnian menggunakan rotary vacuum evaporator merupakan salah satu cara yang efektif untuk meningkatkan kualitas minyak nilam khususnya patchouli alcohol. Minyak nilam hasil penyulingan dari petani dapat ditingkatkan kadar patchouli alcohol dari 25,32% menjadi 42,59%. Improving the Quality of South Aceh Patchouli Oil by using a Rotary Vacuum EvaporatorAbstract :Patchouli oil (patchouli oil) is one of the essential oils produced by the patchouli plant (Pogostemon cablin B). One indicator that determines the quality, quality and price of patchouli oil is the level of patchouli alcohol. The higher the patchouli alcohol content in patchouli oil, the better the quality of patchouli oil. The standard ingredient patchouli alcohol contained in patchouli oil can be prepared by isolating patchouli alcohol. One of the methods used is fractional distillation. The fractionation process is a process of purifying substances/compounds that is used to separate components from a mixture based on the boiling point temperature. Patchouli fractional distillation process can be carried out using a rotary vacuum evaporator. Based on the patchouli alcohol content, the results of fractional distillation of patchouli oil are divided into heavy fractions and light fractions. The purpose of this study was to determine the quality of South Aceh patchouli oil before and after purification using a rotary vacuum evaporator.
