The objective of the research was to determine the influence of granting sludge plant oil palm to the growth of oil palm seeds and find the best treatment  for oil palm growth in main nursery. Research was carried out in land of Plant Laboratory – Agriculture Faculty University of Riau, Bina Widya Campus, Simpang Baru District KM 12.5 Pekanbaru, started from January 2014 to April 2014. This research arranged experimentaly using Completely Randomized Design (CRD),consist by 6 treatments and each treatment was repeated 4 times then obtained 24 experimental units. Each experimental unit consist of two plant seed so that the over all number of harvested seeds is 48. The treatment given was giving oil palm mill sludge, comprising: without giving sludge, sludge 500 g/​​polybag, sludge 1000 g/polybag, sludge 1500 g/polybag, sludge 2000 g/polybag and sludge 2500 g/polybag. The parameters measured were the increase of seeds height, increase amount of leaf midrib, increase of diameter hump, dry weight and root crown ratio. The statistical analysis used was tested using analysis of variance and Duncan's multiple test further at level of 5%. The results showed that giving oil palm mill sludge significant effect on seedling height increment parameter, the increase in diameter hump, seedling dry weight and the ratio of the root crown. However,no significant difference in the number of leaves on the parameters. In addition, this study showed that giving oil palm mill sludge in the treatment of 2000 g/polybag tend to give the better effecton the growth of oil palm seeds.   Keywords: Sludge, oil palm, main nursery

Abstract

The study on growth production of paddy (Oryza sativa L.) Variety IR-64 in the peat soil given Dolomite andCopper (Cu) through leaves have been conducted at Simpang Baru Village Tampan, Pekanbaru City for 5bohths; starting from February to June 2003. The objective of the experiment was identity the effect ofbolomite and Copper given trough leaves and their interaction on the growth and pnKiuction of Rice in the peatisoil. The experiment was arranged in a randomized factorial block design with three replications. The firstfactor was various doses of Dolomite, that was KO (without Dolomite), K l (Dolomite of 0,5 ton/ha), K2 (Dolomiteof 1,0 ton/ha), K3 (Dolomite of 1,5 ton/ha), and K4 (Dolomite of 2,0 ton/ha). The second factor was various dosesof CuSO,, that was CO (without CuSO,), C I (CuSO, of 100 g/ha), C2 (CuSO^ of 200 g/Tta), C3 (CuSO, of 300g/lia), and C4 (CuSO, of 400 g/ha). Parameters observed were plant height, weight of drayed straw, number ofproductive samplings, percentage of well filled rice grain, weight of 1000 .seeds, weight of rice grain. Experi-ment result show tlrnt Dolomite could improve the growth and production of paddy rice and Chopper significantlyincreased weight of dried straw, percentage of well filled rice grain, weight of 1000 seeds and weight of ricegrain. The interaction between Dolomite and Copper significantly increased the weight of dried straw. Ricegrain production treated with 1,5 ton/ha Dolomite and CuSO^ 400 g/ha given trough leiives wiis 2,97 ton/ha.

Abstract

Durian fruit is one of the most popular fruits in Indonesia. Half of the durian fruit is the peel, which produces a lot of waste. The durian peel is not useful and also has no economic value. Durian peel contains fibers that have the potential to be utilized. The utilization of durian peel fiber as a composite natural fiber is an effort to reduce waste from the peels. Improvement of the properties of durian peel fibers can be applied by alkali treatment of the fibers. The purpose of this study is to obtain the cellulose content, tensile strength and impact toughness of durian peel fiber reinforced polymer composites by varying the alkali treatment of the fibers. The volume fraction of fiber and matrix composite was used 50:50. This study varied 0% alkali, fiber alkali as follows: 5% NaOH, 5% NaOH + 3% H2O2, 5% KOH. The results showed the highest cellulose content of 59.48% in the 5% NaOH + 3% H2O2 treatment. It was found that the optimum tensile strength was 8.58 MPa in the 5% NaOH + 3% H2O2 fiber treatment. The highest impact toughness of 2.8 kJ/m2 was obtained in 0% alkali treatment of fiber composite.

Abstract

This community service aims to improve productivity, the efficiency and quality the spice production process at Bumbu Masak Buya, a small and medium-sized enterprise (SME) in Dumai, Indonesia. The primary focus is on upgrading outdated production machinery, specifically roasters, grinders, dryers, and sieves. By modifying or redesigning these machines, the study seeks to improve their performance, durability, and safety. A combined qualitative and quantitative research methodology was employed. The initial step involves a comprehensive assessment of the current production process to identify areas for improvement. Subsequently, the design and implementation of machine modifications were undertaken. It involves a detailed assessment of the current production process, followed by the design and implementation of machine modifications. The impact of these modifications was evaluated to measure their effectiveness in enhancing productivity and product quality. The findings of this study are expected to provide valuable insights for other SMEs in the spice processing industry. By adopting similar strategies of machine modification, these SMEs can improve their operational efficiency, reduce production costs, and enhance the quality of their products.

Abstract

Kontes Kapal Cepat Tak Berawak Nasional (KKCTBN) held by Pusat Prestasi Nasional (Puspresnas) Kemendikbudristek RI aims to encourage innovation in the design and performance of shipping-maritime technology prototypes. The selection of the right material for the catamaran hull is very important because it affects the strength and weight of the ship. Materials such as fiber reinforced polymer, which uses glass fiber, are often used due to their good mechanical strength. However, natural fibers such as pineapple leaf fiber also have potential as composite reinforcement. The combination of natural and synthetic fibers, such as pineapple leaf fiber and glass fiber, in hybrid composites can improve the mechanical properties of the material. The purpose of this study was to investigate tensile and impact properties of pineapple leaf fiber-glass fiber reinforced polymer (GFRP) hybrid composites. Fiber preparation was carried out by separating pineapple leaf to produce fibers, alkaline treatment using 10% NaOH with a soaking time of 24 hours, and oven drying at 100?C for 60 minutes. Polymer as the matrix used was 50% while the percentage variations of pineapple leaf fiber and glass fiber were sequentially as follows 5%:45%, 10%:40% and 15%:35%. It was found that the tensile strength of the 10% pineapple leaf fiber composite was about 114 MPa and impact strength 49.96 J/mm², density 1.19 g/cm3. The results of this study indicate that the resulting composite can be used as an alternative material in the prototype hull of a catamaran type unmanned speedboat.
