PENINGKATAN PENDAPATAN PETANI PADI RAWA PASANG SURUT MELALUI PENERAPAN TEKNOLOGI RAISA DI SUMATERA SELATAN

Tidal swamp land has great potential and opportunities to be used as food production areas, especially rice. The IAARD has produced many technologies and varieties that are adaptive in the growing environment of tidal swamps, but their use and distribution have not been widely known and applied by farmers. The research to increase the income of tidal swamp rice farmers is intended to analyze the tidal swamp rice technology that is being developed. Research in Sukamulya Village, sub district Tungkal Ilir, District of Banyuasin, South Sumatera. The research on 2018 dry season, activities began with a pre-survey which was also used to conduct needs and opportunity studies on farmer groups who would apply tidal swamp rice cultivation technology to tidal swamp rice activities using the RAISA technology approach. Data collection is done using with and without method by means of farm record keeping. Farming analysis is used to analyze collected data. Pre-survey results, based on ranking and priority, there are 5 problems that must be immediately implemented and addressed, namely substandard irrigation, rat control, weed control, drought in the constitutional court, and fertilizer dosage. Based on the agreement, the 5 problems will be overcome by mutual cooperation on the cleaning of tertiary channels, integrated rate control, integrated weed control, planting on time, the use of water pumps, rice variety tolerant to drought, and applying fertilizer doses based on kid fertilizer. The average grain yield of farmers cooperator in tidal swamp rice farms of 5,420 kg/ha is 18.86% higher than that of non-cooperator farmers who average 4,560 kg/ha and the level of profit from tidal swamp farming in farmers cooperator is more feasible when compared to non-cooperator farmers

TIPS MEMILIH DAN MENYIMPAN TELUR YANG AMAN UNTUK DIKONSUSMI

Eggs are perfect foodstuffs because they contain nutrients such as protein, fat, vitamins, and minerals in sufficient quantities. Under certain conditions, the complete nutritional content in eggs can be a good growth medium for microorganisms. It is important to educate the community about how to differentiate egg quality and how to store eggs properly so that people can choose and get eggs of good quality in the long term. The benefit is that they can be more careful in choosing the eggs to buy, and know-how to store eggs properly so that the egg's shelf life can last longer. This education was carried out online during the Covid-19 pandemic Work From Home (WFH) period using the Zoom meet application. The participants in this counseling consisted of housewives and students

UPAYA PENCEGAHAN PENYEBARAN AFRICAN SWINE FEVER DI NUSA TENGGARA TIMUR

The outbreak of African Swine Fever (ASF) disease as a disease that can affect the swine has distributed in many countries including Indonesia. The Province of Nusa Tenggara Timur (NTT) is the biggest swine population in Indonesia being risk because Timor Island directly bordered Timor Leste, which an area that affected ASF. The outbreak of ASF caused a big loss to the economy and the public's fear of consumption of pork and other swine products. The purpose of this activity is to given information about characteristics of good pork quality and appeal public to control and prevent dissemination of ASF. According to this activity, the public knowing ASF as a danger and zoonotic disease, which caused public anxiety to consumption pork and other swine products. Although the public knowing about the danger of ASF, there is no preventive action they know. This activity is a tool for breeders to prevent ASF in their animal husbandry and for the public to know that ASF, not a zoonotic disease. However, consumption of pork and other swine products infected with ASF can spread ASF continuously

SOSIALISASI EDUKASI BAHAYA TOXOPLASMOSIS TERHADAP KELOMPOK PEMUDA USIA PRODUKTIF DI KOTA KUPANG

Toxoplasmosis is a disease of vertebrate animals and it is capable of being transmitted to humans (zoonosis). Toxoplasmosis is caused by the protozoan parasite Toxoplama gondii. Cats are the definitive host of T. gondii where this parasite will enter the cat's body through what it eats such as rats, raw meat, or water that is contaminated with oocysts of the T. gondii parasite. This condition is generally experienced by stray cats or domesticated cats which are often given raw meat. The purpose of this activity is to increase public understanding of the dangers of toxoplasmosis and how to prevent and anticipate the spread of toxoplasmosis in Kupang City. The method used in this community education was through presentation and discussions about the danger of toxoplasmosis. To measure the level of understanding of the participants about the dangers of toxoplasma, a questionnaire is given at the beginning and at the end of the activity. A total of 38 participants from the productive youth groups in Kupang City were involved in this activity.  The result of this activity shows that the public is increasingly educated about toxoplasmosis and how it is transmitted

Sustainable intensification for a larger global rice bowl.

Future rice systems must produce more grain while minimizing the negative environmental impacts. A key question is how to orient agricultural research & development (R&D) programs at national to global scales to maximize the return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, energy, and associated global warming potential) across 32 rice cropping systems covering half of global rice harvested area. We show that achieving high yields and high resource-use efficiencies are not conflicting goals. Most cropping systems have room for increasing yield, resource-use efficiency, or both. In aggregate, current total rice production could be increased by 32%, and excess nitrogen almost eliminated, by focusing on a relatively small number of cropping systems with either large yield gaps or poor resource-use efficiencies. This study provides essential strategic insight on yield gap and resource-use efficiency for prioritizing national and global agricultural R&D investments to ensure adequate rice supply while minimizing negative environmental impact in coming decades
