Abstract

Budidaya rumput laut jenis Kappaphycus alvarezii dan Eucheuma spinosum telah di lakukan di perairan Indonesia yaitu di Lombok, Sumbawa, Nusa Tenggara Timur, Makasar, Situbondo, Prigi, Madura, Lampung dan Sorong Papua. Kappaphycus alvarezii merupakan jenis rumput laut penghasil kappa karaginan yang dapat digunakan sebagai bahan baku di industri makanan, farmasi dan kosmetik. Sedangkan Eucheuma spinosum merupakan rumput laut penghasil iota karaginan yang dapat dimanfaatkan untuk bahan baku di industri makanan. Tujuan kegiatan ini adalah mengembangkan budidaya rumput laut di perairan Kecamatan Buer Kabupaten Sumbawa Provinsi Nusa Tenggara Barat sesuai dengan karakteristik perairannya. Metode kegiatan yang digunakan adalah Focus Discussion Group (FGD) dan demplot budidaya rumput laut secara langsung di perairan laut. Hasil kegiatan ini adalah pada FGD dirumuskan permasalahan dan alternatif solusinya pada budidaya rumput laut. Kegiatan penegmbangan budidaya rumput laut menggunakan metode patok dasar dilakukan di perairan Pulau kaung. Budidaya mengguanakn metode long line dikembangkan di perairan Labuan mapin dan Labuan Burung. Pengembangan kegiatan budidaya tersebut diharapkan dapat meingkatkan ekonomi rumah tangga masyrakat. Kesimpulan dari kegiatan ini adalah upaya pengembangan budidaya rumput laut di perairan Kecamatan Buer telah dilakuakn dengan metode budidaya disesuaikan dengan karakteristik masing-masing perairan perairan.

Abstract

As a result of the outbreak of the COVID-19 pandemic which was followed by the imposition of large-scale social restrictions (PSBB) in Indonesia, it has encouraged people to adopt healthier lifestyles and at the same time carry out a number of environmentally friendly activities. Therefore, it is necessary to make efforts to improve understanding and practice of cultivation as well as guarantee the quality of the food produced, among others by carrying out socialization "how to register horticultural products in urban areas to obtain a Prima3 certificate" as a guarantee that it is safe for consumption. The method used in this activity is the Action Research Method by applying the Participatory Action Program approach from the participants through discussions, and group work in all activities. The results of the activity show that one of the efforts to improve food safety for business actors of Fresh Plant-Origin Food (PSAT) is by registering for food safety certification. Based on survey results from 6 survey locations, 5 of them are still active, namely Japri Farm, UD Rohana and KWT Bunga Matahari, UD Sari Melanting, and UD Sumber Sari. While 1 other location is not active, namely KP. Petemon Asri. There are several business actors in the City of Mataram who have not extended the registration of the commodities they produce. These actors include the Bijak Sari Poktan, the Farmer Family Farmers Group, Japri and Mataram Hydroponics. The results of the demonstration plot showed that the use of liquid organic fertilizer was able to grow lettuce plants well. The best use of vegetable pesticides is demonstrated by plant-based pesticides extracted from papaya leaves. Botanical pesticides are pesticides whose active ingredients come from plants or herbs and other organic materials that can control pest attacks on lettuce plants, both as repellents, antifedans, attractants.

Abstract

The use of natural enemies as pest control has long been known, but has been largely replaced by the rapid development of chemical pesticide industry technology, especially since the green revolution. One alternative pest control technology that is quite promising to be developed is the use of biological agents (predators or parasotoids) that have more natural characteristics than chemical characteristics. With the presence of natural enemies which are then used to suppress pest populations, it will be safe for human health and the environment. It can be hoped that the agricultural products produced will be acceptable and highly competitive on the global market. Considering the Sembalun area as a tourism destination, it will be very relevant if the local community understands good horticultural practices. The intervention of using technology for farmers as an alternative in good Horticultural Cultivation is highly expected by farmers in the Sembalun area. Therefore, assistance is needed to implement integrated Pest Management in good Horticultural practices. The method used in this activity is the Action Research Method by applying a Participatory Action Program approach from participants through discussion and group work in all activities. The result is that farmers are very interested in implementing good horticultural cultivation, especially with habitat management approaches such as using refugia plants to control pests. Participating farmers increase their knowledge and skills to recognize differences in pests and natural enemies (predators and parasitoids) found on potato plants that are integrated with refugia plants. The target group has increased knowledge and understanding of the importance of implementing Integrated Pest Management (IPM) practices in horticultural cultivation. It is hoped that training and assistance activities for healthy horticultural cultivation efforts will continue both by the university team and related agencies. This kind of activity needs to be continued by the participating group and spread to other groups nearby. There is a need for assistance in applying for Prima 3 and Prima 2 food safety certification to farmer groups in the Sembalun Agrotourism Area, so that the number of products from certified horticultural business actors will increase. Activities to implement Integrated Pest Management in horticultural farming business groups in the Sembalun Tourism Area need to continue

Abstract

The utilization of non-wood biomass residues as alternative solid fuels is important for supporting low-carbon energy transitions and circular bioenergy development. This study evaluated the quality and energy performance of charcoal briquettes produced from vegetative residues of sugar palm (Arenga pinnata), specifically fronds, fruit stalks, and a mixture of both materials. A completely randomized design was applied, and the briquettes were assessed based on physical properties, proximate composition, combustion performance, and charcoal yield, with SNI 01-6235-2000 used as the primary quality benchmark. The results showed that all briquette types had very low moisture content (1.69–2.03%) and high calorific values (5,427–5,985 cal g⁻¹), meeting the SNI requirements for these parameters. Significant differences among plant parts were observed in ash content, volatile matter, and fixed carbon content (p < 0.05), indicating that raw material characteristics strongly influenced briquette quality. Briquettes produced from sugar palm fronds exhibited the highest fixed carbon content and calorific value, as well as the lowest burning rate, reflecting better thermal stability and longer combustion duration. Meanwhile, briquettes made from the mixture of fronds and fruit stalks showed the lowest ash content and the most balanced quality profile. Although some proximate parameters, particularly volatile matter and fixed carbon, did not fully meet the SNI limits, these limitations are process-dependent and may be improved through optimization of carbonization conditions. Overall, sugar palm vegetative residues represent a promising non-wood biomass resource for sustainable charcoal briquette production within a circular bioenergy framework.
