When studying demography or economics we read An Essay on the Principle of Population, a famous treatise of Thomas Robert Malthus published in eighteenth century. We learn and get the understanding from the book’s Malthus that the world will be overpopulated. World population is correlated with food provision, and people starve and starvation will happen in many parts of this globe, then people will be suffering from diseases. Scarce of food or insufficient nutrition will stop the population growth. Malthus predicted the increase of food production was unbalance to the increase of population. East and South East Asian belong to regions of rapid increase in population growth, but the report of Gavin as the United Nations Expert Paper stated like that, demographic theories of Malthus have been denied and not perfect. The optimism is stand to the reason because the efforts are always be supported and helped by the generous and well concerned of wealth and developed countries in Europe ...

Pollination is an important factor in the formation of the oil palm fruit. Establishment of oil palm fruits decreased resulting in reduced production of fresh fruit bunches (FFB) as a result of natural pollination process are less effective. The aim of research to find a solution increases the amount of oil palm fruit with artificial pollination. The method used is an experimental method in the form of completely randomized design (CRD), with three replications: a1 = size of 10 mesh pollen and pollen a2 = size 12 mesh with pollination time (09: 00-10: 00 pm), (12 : 00-13: 00 pm), and (16: 00-17: 00 pm). Tests using Anova and advanced test using Duncan's Multiple Range Test (DMRT). The results showed pemanfaataan size of pollen size of 10 mesh and 12 mesh in artificial pollination significantly affect the formation of the amount of fruit in the bunch. It was described by the percentage of successful fruit formation over 80% with an average normal shape.

Tomato is a commodity that is widely cultivated in Indonesia. The abundtance of tomato crops in Indonesia causes unstable tomato prices in the local market. One of solutions to this problems is by exporting tomatoes to another country. However, durability of tomato during storage is still a constraint. This can happens because the tomatoes are stricken with microbes and various post-harvest pest. It has been known that the rhizome of java grass (Cyperus rotundus L) that grows wild in Indonesia contains antimicrobial compounds that are able to prevent the growth and the arrival of various types of microbes and post-harvest pests. This study aims to determine the influence of antimicrobial content of rhizome extract of java grass (REJG) towards growth and the presence of microbes and post-harvest pest on tomatoes, in effort to improve the durability of tomato during storage.

Egypt has been famous as agricultural country since ancient times. Most Egyptian horticultural and food crop plants are shrubs or small trees with shallow root systems. These plants are susceptible to drought and have a little or no hydrological effect. Egyptian agriculture is mostly dependent on the Nile water (82.59%). Desert areas can be ecologically reclaimed or restored to agronomically productive areas if socioeconomic, cultural, and political factors permit the restoration. Afforestation is when a desert is turned into a woods or forest as a climate change agent and water reservoir. This survey found that Egyptian land was greener than Indonesian land. The availability of the Nile water should be managed as effective as possible to accelerate Egyptian afforestation projects. Egypt may imitate Indonesian success in re-greening the Gunungkidul region of Jogyakarta with the Wanagama forest. The afforestation program affects agricultural practices in Egypt in both the near- and l...

However, the practice of hydroponics in rice plants is still limited due to the availability of special nutrient. This study aims to determine the benefits of silicate rice husk extract on the growth of rice hydroponics. The research design used was complete randomized block design. The observed growth parameters are : plant height, electrical conductivity of nutrients and pH. The observed data were analyzed using variance analysis. If the results of variance analysis are significant, the analysis will be proceed with Duncan multiple range test. The results showed that application of rice husk silica extract of 20 ml/L through leaves gave the same response with sodium silicate (Na2O3Si) appli...

Torch Ginger (Etlingera elatior (Jack) R. M. Smith) is plant material that can be used as a medicine, food, cosmetics, and bio-pesticides. The existence of torch ginger in nature is becoming more limited due to the utilization of health care services mainly as a medicine continues to increase. In conventionally, plant propagation of torch ginger is derived from a rhizome, but seedlings produced tend to have the level of low proliferation and susceptible to infections of soil pathogens. This research aimed to know the influence of sucrose and BAP concentration on bud growth of torch ginger in in vitro. The research was conducted in the Tissue Culture Laboratory Universitas Islam Negeri Sunan Gunung Djati Bandung. Research method used was a descriptive design with experiment treatments i.e. sucrose (20 g/L, 40 g/L, and 60 g/L) and BAP (0 mg/L and 1 mg/L). The result showed that the use of sucrose 40 g/L + BAP 1 mg/L gave the best response to the shoot growth on 6 WAI and capable to pr...

One of the objectives of the education in Indonesia is " mastering science and technology ". Human induced climate change requires urgent action. Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes. The Qur'an explains destruction has appeared on land and sea because of what the hands of men have earned (by oppression and evil deeds). Climate change has been affecting farmers difficult to plan their planting activities. Maintaining organisms to survive in warmer and unpredictable condition is an obligation and considered as devotion to the Almighty God. Technology to adapt rami plant in warmer condition of this earth is the purpose of experiment which was conducted in agricultural field practice of

Three experiments in three different biophysical environments were conducted in Jatinangor, Sumedang District, Jatitujuh. Majalengka District and Bandung District of West Java Province, Indonesia. The experiment were conducted to evaluate the environments, seasons, manure, nitrogen and potassium effect on the physiological aspects and yield of ramie plant (Boehmerianivea L. Gaud).The locations diverse at different elevation, rainfall type and soil type and atmospheric regimes. The experiments passed the years 2000-2001. The experiment in Sumedang regency was continued with two other experiments in 2007, and experiment in Bandung district was conducted in 2014.The field experiments design used in all the locations were randomized block design arranged in factorial pattern with two factors and two replications. Climatic analysis is done by comparing the atmospheric data of 2000-2001 and the data of 2002-2007 and the data of 2014. Assumed that all the local atmospheric data are atmospheric data under influence of climatic global change. Results of the experiments were: Jatitujuh region is not suitable for ramie cultivation. Dosage of waterw3=35%-40% of Field Capacity affecting sufficient growth on plant.The minimum dosage at which plant survive to produce yield is representing the most efficient input of production.Water supply for ramie plant could be designed to the most efficient volume to maintain the need of metabolism.

The first verses revealed to prophet Muhammad SAW is begun with the word to read. This word is an instruction to all Moslem to read in the sense of to think of the creation of the creator. Someone still has the opinion that Islam discourages the development of science. This accusation is absolutely not true. The process of conclusion making in the science and the religion is something different. Religion is based on faith and science is based on human investigation or rational and logical facts. Quranic verses contain hints and a lot of scientific facts, but they are not scientific theories. Reading in the meaning of studying the nature is the first order from the Almighty God to prophet Muhammad. Nature and all creatures are created in balance. Creatures are all in pairs. Nature is prepared and maintained in systematic mechanism. Photosynthesis is considered to be the first chain of living mechanism of creatures which depend on food and on the supply of fire (energy) as stated in verse 80 chapter Ya Sin. The photosynthesis proses is the process of synthesis of carbon dioxide and the water. Water has unique physical and chemical properties. We can heat it, evaporate it, freeze it and use it for solving or combining other things. All living creatures require water, and almost the processing happening need water. Through the scientific observations and the natural evidences revealed, now we believe in the Qur'an that it is true all the times. Man is ordered to utilize their all capacities of mind and intellect lo reveal the secret of the nature and the whole universe. In this way people may come to conclusion to have firmer belief in God, the Creator 1 Scientific Encouragement Studying the verses guiding or enlightening the development of science may commence from any verses saying about the creation. Such the verse is verse number 2 of al-'Ala chapter : Alladzi khalaqa fasawwa (Who has created (everything) and proportioned it). It is very interesting subject. We are all aware of this verse is applied to plant and animal and also to inanimate things. From micro subject point of view, we got the understanding that all maters are composed of extremely small particles called atoms consisting of charged particles and uncharged particles called neutrons. While the charged particles are of two kinds, negative called electrons and positive called protons. There are always in pairs and in equalibrium. In the world of vegetation, plants are propagated with two ways of propagation generatively (by generative cells : seeds) and vegetatively (somatic cells). There are male and famale flowers to

Kopi diusahakan oleh manusia dalam memenuhi kebutuhan hidupnya sebagai buah yang berfungsi sebagai minuman penyegar. Orang Eropa yang hidup pada wilayah iklim sub-tropis dan dingin sangat membutuhkan berbagai minuman yang menyegarkan. Dalam era penjajahan orang eropa banyak memikirkan upaya memenuhi kebutuhan hidupnya di daerah penjajahannya. Kopi menjadi penting dan banyak dimanfaatkan bukan saja oleh orang di eropa tetapi juga orang di Negara tempat kopi diproduksi. Orang semakin mengenal peran kopi sehingga berbagai kreasi pemanfaatan kopi. Kopi sebagaimana teh dan kakao merupakan tanaman penyegar. Komoditas itu diproduksi dan diambil khasiatnya sebagai produk yang mengandung zat aktif yang merangsang organ hidup tertentu. Alkaloid kafein dalam takaran tertentu banyak manfaatnya bagi hidup manusia. Sejak abad 20 sampai sekarang produksi kopi dunia terus melonjak berlifat. Kopi diproduksi di Amerika Tengah dan Amerika Selatan, Negara-negara di Afrika dan Negara-negara di Asia. Indonesia juga merupakan penghasil kopi yang penting, memproduksi sekitar 3%-4 % produksi dunia.. Brasilia dan Colombia menghasilkan sekitar 40% produk kopi dunia, tetapi kadang mengalami surut karena gangguan penyakit karat daun (Hemeleila vastatrix). Filipina juga penghasil kopi yang cukup besar.
