His study aims to analyze the extent to which a mixture of wood waste and used newsprint can be used as raw material for making paper.This study used a completely randomized design with two replications. where the treatment given is a mixture composition between waste wood pulp and old newsprint pulp, each consisting of 0 : 100% (A), 30% 70% (B), 50% : 50% (C), 70% : 30% (D) and 100% : 0% (E) of oven-dry weight of pulp per sheet of paperThe physical properties of paper pulp tested in the form of tear index, tensile index, crack index and folding resistance significantly affect the composition of the mixture of wood waste and used newsprint.The value of tear index, tensile index and folding resistance tend to decrease with the increase in the percentage of used newsprint to the composition of the mixture, while the value of the crack index increases. Wood waste and used newsprint can be used as raw materials in pulp and paper manufacture, especially in the treatment of mixed composition C (50%:50%.)

This research was motivated by the importance of workers harvesting oil palm fruit on productivity. One of the stages of oil palm cultivation is harvesting, which is one of the key determinants of oil palm productivity. Productive labor can be seen from the achievement of targets set by the company or the difference between the results obtained and the task bases that have been determined by the company. This has prompted researchers to analyze the factors that influence the productivity of oil palm harvesting workers. The purpose of this study was to analyze the effect of age, years of service, and level of education on the productivity of harvesters and to calculate the value of labor productivity in oil palm harvesting. In data analysis using descriptive method, where the data obtained from direct interviews with oil palm harvesting employees by asking several questions that have been prepared and will be processed using the SPSS method, respondents were taken as many as 35 respondents from all afdeling using the Slovin formula. The results showed that the labor productivity of oil palm harvesters at PT. WIN is significantly influenced by age and education factors. Meanwhile, tenure does not have a significant effect on labor productivity of harvesters. The productivity of harvesting labor that was achieved was 135 hrs / HOK, having exceeded the company's target of 110 hrs / HOK.

This research is based on the background that oil palm plantations are a form of community farming that cultivates oil palm plants with production in the form of fresh fruit bunches (FFB) as one of their sources of livelihood, although investment in oil palm plantations requires a relatively long period of time compared to oil palm plantations. with other plantation commodities. The purpose of this study was to determine the oil palm farming business in Saliki Village based on FFB production and palm oil prices. The data collection method used in this study is a qualitative method, which is a research that is used if the research factors cannot be quantified or cannot be calculated so that the variables cannot be expressed with numbers such as perceptions, opinions, assumptions and so on. According to qualitative research theory, in order for the research to be of really high quality, the data collected must be complete, namely primary data and secondary data. From the results of this study, it can be concluded that oil palm farming in Saliki Village based on the production of fresh fruit bunches and the price of palm oil really helps farmers increase their income from farming by selling large quantities of produce and high selling prices. The income they generate from oil palm plantations can meet their daily needs. In addition, the community (oil palm farmers) can buy vehicles, renovate and even build houses from the results of the oil palm plantations. The results of this study are to provide information to the community in Saliki Village in order to be able to improve oil palm farming.

Indonesia memiliki hutan tropis yang kaya akan beraneka ragam tumbuhan yang dapat digunakan sebagai obat tradisional, mulai dari akar, batang, daun, sampai buah semuanya mempunyai nilai yang besar dan dapat digunakan sebagai obat untuk kesehatan serta berasal dari berbagai suku yang berada di Indonesia. Senyawa antimikroba didefinisikan sebagai senyawa biologis atau kimia yang dapat menghambat pertumbuhan dan aktivitas mikroba. Tujuan dari penelitian ini adalah untuk mengetahui bioaktivitas anti bakteri ekstrak etanol (C2H6O) dari tiga jenis tumbuhan Pulutan (Urena lobata L), Kadamba (M. speciosa) dan Buah Ketitir (Brucea javanica L. Merr). terhadap bakteri Streptococcuss mutans dan Escherichia coli. Metode pengujian antibakteri dilakukan dengan metode difusi agar sumuran dengan modifikasi dengan menggunakan ekstrak etanol. Ekstrak etanol tumbuhan obat pulutan (Urena lobata L), kadamba (Mitragyna spesiosa), dan buah ketitir (Brucea javanica L. Merr) memberikan penghambatan lemah sampai dengan kuat terhadap pertumbuhan bakteri Escherichia coli dan Streptococcuss mutans. Konsentrasi ekstrak etanol 200 (μg/well) memberikan penghambatan dengan klasifikasi kuat.
