Abstract

Daun bandotan (Ageratum conyzoides Lin) merupakan salah satu tanaman yang digunakan sebagai obat tradisional daun bandotan mempunyai berbagai khasiat, salah satunya sebagai antibakteri Tujuan penelitian ini adalah mengetahui efek antibakteri ekstrak daun bandotan terhadap pertumbuhan bakteri Propionumbacterium acnes, Escherichia coli, dan Streptococcus mutan. Simplisia daun bandotan diekstrak menggunakan etanol pada suhu kamar, kemudian dilakukan pemekatan ekstrak menggunakan vacuum rotary evaporator sehingga diperoleh ekstrak kasar. Analisis fitokimia dilakukan untuk mengidentifikasi golongan senyawa metabolit sekunder yang meliputi flavonoid, alkaloid, tanin, saponin terpenoid dan steroid. Pengujian aktivitas antibakteri menggunakan metode difusi sumuran dengan konsentrasi 100, 200, 400, dan 600 µg/well untuk mengetahui Konsentrasi Hambat Minimum. Chlorampenicol digunakan sebagai kontrol positif dan aseton sebagai kontrol negatif. Hasil penelitian dinyatakan bahwa ekstrak daun bandotan mengandung senyawa metabolit sekunder yaitu flavonoid, saponin, tannin, dan steroid. Sedang alkaloid dan terpenoid tidak terdeteksi. Hasil pengujian aktivitas antibakteri eksrak etanol daun bandotan berpotensi sebagai bahan antibakteri dengan KHM pada E.coli antara100-200 µg/well dan pada P. acne dan S. Sobrinus di bawah 100 µg/well.

Abstract

Oil palm is one of the potential commodities whose cultivation trend began in 2003 in EastKalimantan which has the characteristics of hilly land. Oil palm itself is preferable to grow at analtitude of 400 m asl with a slope of up to 23% or at 12°.Therefore, this research is motivated todetermine the yield of oil palm plantations in certain land slope classifications. The study wasconducted on 2 afdeling which have different land classifications with an area of ± 14,000 ha.Thenfor comparison, it was taken through production data in 2019 with 2 treatments and 12 replications,which were processed using Analysis Of Variance (ANOVA) Two Way Anova. Primary data wereobtained through field observations, as well as soil sampling, which were analyzed directly for soilphysical properties and laboratory for chemical properties including pH H2O, Nitrogen (N),Phosphorus (P), Potassium (K) and Magnesium (Mg.). The results of the research on the effect ofslope on oil palm production by various methods indicate that the land slope factor does not have asignificant effect on oil palm productivity.

Abstract

This research is motivated by the importance of knowledge about alternative pest control that is safe but still supports the achievement of maximum oil palm production so that the balance of the oil palm plantation ecosystem can occur. The purpose of this study is to determine the technical cultivation and benefits of the Turnera subulata flower as a host plant for predators and parasitoids that function as biological agents for caterpillars and can be a reference for controlling caterpillar pests that are safe and still support the achievement of maximum oil palm production. The method used in this research is field observation and documentation from the company. The scope of this research covers the technical aspects of the biological control of caterpillars. This research data uses primary data and secondary data obtained from field observations and literature studies in the form of company reports in the form of percentages. The realization of Turnera subulata planting reached 21,659 m on CR road and 19,914 m on MR road. The planned planting of Turnera subulata is 57,200 m on the CR road and 45,823 m on the MR road. For the realization of the planting of Turnera subulata itself using seeds that are ready for planting. To obtain the seedling, the company conducts its nurseries. The seedling technique was done using the stem cutting technique. The stems for the cutting technique were taken from the Turnera subulata plant stems that have grown large. The type of stem taken is the old Turnera subulata plant stem. For seed care, the seeds are always watered every morning and evening like other flower plants. For the natural enemy insects, been proven that there are 6 natural enemy insects associated with Turnera subulata plants, 3 predators, and 3 parasitoids, each with a large enough number of insects. The types are Eocanthecona furcellata, Cosmolestes sp., Sycannus dichotomus, Spinaria spinator, Fornicia sp., and Chaetexorista javana. The development and the implementation of a control system are by optimizing the conservation and utilization of these biological control agents is a wise step to obtain an effective, efficient and environmentally friendly technique for controlling caterpillars. The presence of Turnera subulata plants can be used to suppress the development of pests in oil palm plantations by increasing the potential for natural enemies, both predators, and parasitoids. The diversity of wild plants with flowers can increase the variety of insects so that the balance of the ecosystem occurs.

Abstract

This research is motivated by the processing of palm oil, transportation factors get special attention.The transportation of palm fruit from the garden to the factory should be as fast as possible so that thefruit harvested today can be processed directly so that free fatty acids are not high. Extensive oil palmplantations and garden conditions far from the factory, it will be more difficult to regulate the entry ofFresh Fruit Bunches (TBS) to the Palm Oil Factory (PKS), so that the company must have a goodmanagement system that can run effectively and efficiently so that it needs proper transportation forperushan so that it can transport all tbs harvested by minimizing time, cost and maintain the quality ofTBS.From the description above, the formula that can be formulated in this study is to know the time oftransportation, the needs of transport equipment and what obstacles are encountered at the time of TBStransportation. While the limitations of the problem there is tbs transport research contained in fadelingBrafo, Alfah and Delta with different distances (near, medium and farthest). The purpose of this researchis to know the process of planning the needs of TBS conveyances, as well as knowing the obstacleswhen transporting TBS.The results of research conducted at PT. Berau Karetindo Lestari shows that tbs transportationplanning includes the production of TBS per day, TBS transport time, availability of conveyance,transportation needs and constraints in transportation. In Bravo afdeling requires 2 units of tarktor, forafdeling Alfah 4 units taktor, and afdeling Delta requires 3 units of tractor. As for the needs of the truckon Loading ramp 1 as many as 10 units and Loading ramp 2 to 8 units. This is obtained after calculatingthe number of transport equipment needs to transport TBS every day. For the overall needs of thecompany, tractors are needed as many as 17 and DT as many as 18 units. As for the obstacles at thetime of tbs transportation, namely, the road conditions in TPH are not good and the distance of thefactory is so far that it takes so much time to get to the factory.

Abstract

Good management of palm oil harvesters can reduce labor error rate during harvest, increasing work productivity, while also facilitate the achievement of company goals. This research aims to determine the effect of workforce characteristics, namely age, length of work and education on the productivity of palm oil harvest, as well as to determine whether harvest productivity is in accordance with company targets. The results of this research are expected to provide input for companies regarding the productivity of palm oil harvest and also as a reference for recruiting harvesters. Data analysis method used in this research is multiple linear regression. Result is determined using census method, as the sample is less than 100 people with the number of respondents reached 52 people. Based on the research results, it was indicated that length of work, age and education do not affect the productivity of harvesters at Long Ayan Estate PT. Berau Karetindo Lestari. The average labor productivity of harvesters reached 281.06 bunches/weekdays; thus, the workforce was able to achieve the target set by the company of 175 bunches/weekdays.
