Abstrak Agribisnis karet saat ini sedang mengalami kondisi yang kurang menguntungkan. Hal ini disebabkan oleh menurunnya harga karet beberapa tahun terakhir serta meningkatnya biaya produksi terutama biaya penyadapan. Salah satu upaya yang dapat dilakukan dan dapat menjadi suatu pemikiran adalah dengan melakukan penundaan buka sadap tanaman karet. Tulisan ini mengkaji penundaan buka sadap tanaman karet dengan dua pendekatan yaitu: penundaan buka sadap tanaman karet dengan merubah kriteria matang sadap pohon dari 45 cm menjadi 50 cm; dan penundaan buka sadap tanaman karet dengan merubah kriteria persentase matang sadap kebun. Analisis menggunakan data percobaan Lukman (1979; 1980), Samuel et al. (2012), Hendratno dan Amypalupy (2008), dan Nugraha et al. (2015). Hasil kajian menunjukkan bahwa penundaan buka sadap dengan merubah lilit batang dari 45 cm menjadi 50 cm dapat meningkatkan produktivitas per penyadap. Penundaan buka sadap hingga lilit batang mencapai 50 cm akan ekonomis dengan pemilihan klon yang memiliki produktivitas awal yang tinggi. Untuk  menunda buka sadap dari lilit batang 45 cm menjadi 50 cm diperlukan waktu 6-12 bulan tergantung kerapatan tanaman dan jenis klon. Kriteria matang sadap kebun yang berbeda sesuai jenis klon dan perubahan harga masih menguntungkan secara ekonomis. Perlu kajian yang lebih luas mengenai penundaan buka sadap. Kata kunci: karet, buka sadap, penundaan Abstract Currently, agribusiness of rubber is experiencing unfavorable condition. This is due to the declining of rubber price in the last few years as well as increasing of cost of production especially the cost of tapping. An effort that could be done was by delaying the opening of rubber. This paper examines the delay in opening of rubber with two approaches, i.e. delaying of rubber opening by changing the criteria of tree maturity for tapping  from 45 cm to 50 cm; and delaying of rubber opening by changing the criteria for the percentage of mature tree. Analysis was conducted using the data of Lukman (1979;1980), Samuel et al. (2012), Hendratno and Amypalupy (2008), and Nugraha et al. (2015). The results showed that the delay of opening by changing the girth of 45 cm to 50 cm could increase productivity per tapper. Delaying of opening until reaching the girth of 50 cm will be economical with the selection of clones that have high initial productivity. To delay opening from the girth of 45 cm to 50 cm took 6-12 months depending on the density of the plants and clones. Criteria of field tapping maturity to suit different types of clones and price changes are still economically viable. A broader study on the delaying of rubber opening was needed.

Elevated atmospheric CO2 concentration (e[CO2]) can stimulate the photosynthesis and productivity of C3 species including food and forest crops. Intraspecific variation in responsiveness to e[CO2] can be exploited to increase productivity under e[CO2]. However, active selection of genotypes to increase productivity under e[CO2] is rarely performed across a wide range of germplasm, because of constraints of space and the cost of CO2 fumigation facilities. If we are to capitalise on recent advances in whole genome sequencing, approaches are required to help overcome these issues of space and cost. Here, we discuss the advantage of applying prescreening as a tool in large genome×e[CO2] experiments, where a surrogate for e[CO2] was used to select cultivars for more detailed analysis under e[CO2] conditions. We discuss why phenotypic prescreening in population-wide screening for e[CO2] responsiveness is necessary, what approaches could be used for prescreening for e[CO2] responsiveness, and how the data can be used to improve genetic selection of high-performing cultivars. We do this within the framework of understanding the strengths and limitations of genotype–phenotype mapping.

The low productivity of milkfish produced by traditional technology encourage the development of new farming technologies to increase productivity. Semi-intensive technology has evolved since the 2000s. However, this technology increases the cost of production because of the additional input of artificial feed. One of the regencies which produce milkfish using both traditional and semi-intensive technology is Karawang Regency. The objective of this research were to analyze profit and cost efficiency in traditional and semi-intensive techonology. The method of data collection conducted purposive as many as 30 milkfish farmers with traditional technology and 33 milkfish farmers with semi-intensive technology. The results show that semi-intensive technology provides a higher level of productivity and higher profitability. However, traditional technology was more efficient than semi-intensive technology. This condition causes the milkfish cultivation with traditional technology are still exist because it provides a higher return to capital.

The ability to move on different types of soils is one of the main indicators of the efficiency of mobile vehicles in off-road conditions. The movement of such special mobile machines is carried out due to the interaction of the propulsion with the support surface. Therefore, significant reserves to increase productivity and reduce the cost of technological and transport works are laid in reducing energy consumption when the engine interacts with the surface. On the process of interaction of the wheel drive with the deformable support surface it is established that the parameters of this interaction depend on a number of factors: normal load, angular velocity and torque. In the General case, the parameters of interaction of each engine change when changing the mode of movement of the wheeled vehicle, and the ability to change the air pressure in the tires when driving on different support surfaces allows to increase the performance of the wheeled vehicle In the study of the caterpillar, it was found that the pitch of the caterpillar, the stiffness of the caterpillar, the angular stiffness of two adjacent tracks, reducing the pitch of the caterpillar chain, reducing the stiffness of the caterpillar, increasing the angular stiffness of two adjacent tracks, affect the efficiency of the machine. The scientific novelty of the study is to develop a method of choosing the engine of a special mobile machine that works off-road, in the process of its design. Wheel or crawler solutions will mainly determine the performance and efficiency of special purpose vehicles. The choice of engine for special mobile machines is based on a set of criteria. The criteria determine the importance of the implementation of the tasks in relation to the efficiency of functioning. Knowing the sowing capacity of the soil, and taking into account the possibility of movement of a particular special mobile machine depending on the type of soil, you can choose one or another type of engine.

Price law is the theoretical expression of the relation between the value of the product and the quantity of labour. This relation is one of the basic law of goods production. In different types of production the principle is manifested in different forms. In the simple production of goods prices tend to conform to the value of the goods. In the classic form of capitalism the principle operates through the law of average profit. The transfer of capital to different branches of economy ultimately results in a price which comprises the cost of production and average profit. At the monopoly stage prices comprise the cost of production, average profit, and the extra profit As regards the socialist self-governing goods production such as exists in Yugoslavia, different opinions are current concerning the forms of operation of this principle. Two principal variants are prevalent: the principle of average income and the principle of specific cost of production.

Few educational institutions have well maintained microscopes that facilitate the experience intended by the creators of their teaching texts. The cost of putting a high quality selection of the different types of microscopes at every educational institution for access by all students is prohibitive. The advent of the Internet and the rapid proliferation of computers at educational institutions offer the prospect for dramatic improvements in microscopy education.We present an Internet based digital microscopy system with unique features for education. We have developed a unified architecture for management and transmission of live and stored microscope data over the Internet. The system consists of a combination of software and hardware. The hardware includes a microscope with a motorized stage, focus, and optionally a motorized nosepiece. Standard off the shelf components for each of the items can be used so that the user is afforded great flexibility in utilizing available hardware. Image acquisition is done by attaching a video camera to the microscope. Both analog and digital video cameras are supported, although it should be noted that users have experienced outstanding results with relatively inexpensive analog cameras.
