“…Pupuk hayati merupakan pupuk yang mempunyai kandungan mikroorganisme yang apabila diaplikasikan pada tanaman mampu memacu pertumbuhan tanaman dengan cara mengikat nitrogen dari udara, melarutkan fosfat yang terikat, memecah senyawa organik kompleks menjadi senyawa yang lebih sederhana (Suwahyono 2011). Selain itu, Ca juga berfungsi dalam pertumbuhan sel dan pemanjangan sel, sehingga berpengaruh pada pertumbuhan panjang stolon (Tehubijuluw et al 2014).…”

Gotu kola is one of the medicinal plants that has begun to be cultivated by the Indonesian people. It’s cultivation needs to follow the GAP to produce the qualified yield, including the use of fertilizers. Biofertilizers have been widely developed to reduce adverse effects of chemical fertilizers to the environment, thus an organic cultivation method can be an alternative. The aim of this study was to determine the effect of biofertilizer on growth and yield of gotu kola. This research was an experimental study with a completely randomized design (CRD) using 8 planting media treatments consisting of (a) Soil + manure + dolomite; (b) Soil manure + 1 g biofertilizer; (c) Soil + dolomite + 1g biofertilizer; (d) Soil + manure + 3 biofertilizer; (e) Soil + dolomite + 3 biofertilizer; (f) Soil + manure + 5 g biofertilizer; (g) Soil + dolomite + 5 g biofertilizer; and (h) Soil + 3 g biofertilizer. Parameters observed were leaf area, stem length, number of leaves, number of tillers, fresh weight, dry weight and asiaticoside content. The results showed that combination treatment of biofertilizer (1 g) with dolomite (30 g) gives better effect in increasing the number of tillers and number of leaves, while the combination of biofertilizer (5 g) and dolomite (30 g) is the best for asiaticoside levels in gotu cola.

One waste that can be used as raw material for biodiesel is avocado seeds. Generally, biodiesel from avocado seed oil is synthesized using a homogeneous base catalyst, NaOH or KOH. However, the yield of Free Fatty Acids (FFA) is still low, so it is necessary to make biodiesel using heterogeneous base catalysts such as calcium oxide (CaO) and super base CaO from eggshell waste. Avocado seed oil biodiesel was synthesized using the method of transesterification with a ratio of 1:6, and a super base CaO/CaO catalyst of 1.5% (w/w) of the weight of avocado seed oil was added. The use of the CaO catalyst produced a Fatty Acid Methyl Ester (FAME) of 98.21% with a biodiesel yield of 73.77%, while the use of a super base CaO catalyst produced a FAME of 98.47% with a biodiesel yield of 74.50%. Characterization of biodiesel using FTIR shows the presence of methyl, ether, alcohol, carbonyl, and ester functional groups (C=O and C-O bonds), which are characteristics of the resulting biodiesel trans-esterification. Based on the yield and physical and chemical properties, the avocado seed oil biodiesel produced is better using the super base CaO catalyst than the CaO catalyst.

Conversion of the Cerbera manghas L seed oil into biodiesel using homogenous catalys through esterification and transesterification stage have been done. Esterification process was carried out using mole ratio of methanol/oil 1:3, temperature 60-65°C for 2 hours with acid catalyst 1.25% H2SO4. The products were separated between methanol and triglycerides continued by transesterification process using mole ratio of methanol/oil 1:6. Initialy, the methanol have been reacted to NaOH catalyst using the catalyst variation 0.1; 0.2; 0.3; and 0.4%, for 2 hours and the reaction temperature 60-65°C. Biodiesel results were analysed by FTIR, GC-MS, and ASTM. The result show that the optimum biodiesel obtained on weiggt of catalyst is 0.3% NaOH. ASTM the test of results were obtained the propesties of the biodiesel there were: specific density of 0.8808 g/cm3, kinematic viscosity of 6.511 mm2/s, flash point 168°C, pour point 9°C, cloud point 12°C and conradson carbon residual 0.165 wt%.
