Densification of rice straw such as compacting and pelletizing is an important process to increase the density of rice straw resulting in a reduction of transportation cost. Within this research, we conducted a techno-economic investigation of rice straw densification to produce compressed bales and pellets, which are later used for animal feed. In line with the main deliverable of the performance of rice straw compacting and pelletizing processes, we also looked into the quality of the product in terms of uptake and digestibility of the cattle feed which could be improved by adding amendments such as urea during the compacting process. The compacting technology resulted in a 400% increase of bale density (from 94 to 390 kg.m-3). This could reduce transportation costs by about 60% for a 60 km driving distance using trucks. The net profit that resulted from compacted bales was USD 0.0062 kg-1. Although the pelletizing technology increased the cost of the densified product by 40–50%, its density increases by 700%, from 94 to 666 kg.m-3. The enriched-rice straw pellets contained 12.1% protein, 2.8% lipid, 32.7% raw fibre, and 11.2% ash. In addition, a test of this product for cattle feeding illustrated an increase in its eating desirability for cows. Findings from this study contribute to reducing feedstock cost and developing densified rice straw products. These, therefore, provide more alternative options to increase the benefits from rice production and thus, reduce the unsustainable burning of rice straw in the field. Nén ép rơm là quá trình quan trọng và cần thiết để tăng khối lượng thể tích với mục đích giảm chi phí vận chuyển. Trong nghiên cứu này, chúng tôi đã thực hiện nghiên cứu đánh giá tính khả thi về kỹ thuật và kinh tế đối với nội dung nén ép rơm cuộn và ép viên rơm.

Abstrak: Kabupaten Lumajang memiliki lahan pertanian dan perkebunan dengan komoditi utamanya adalah tanaman padi, jagung dan kopi. Banyak sekali limbah yang belum termanfaatkan, berawal dari program KKN, potensi daerah di Desa Kalibendo, Kecamatan Pasirian, Kabupaten Lumajang sangat potensial untuk dikembangkan salah satunya “Bioteknologi fermentasi jerami padi tinggi nutrisi, guna meningkatkan kemandirian dan kesejahteraan peternak di Desa Kalibendo, Kecamatan Pasiria, Kabupaten Lumajang”. Pendampingan dari instansi terkait edukasi dalam bioteknologi pengolahan pakan berkualitas secara mandiri dari bahan baku lokal yang ada dari limbah pertanian setempat dapat memenuhi ketersediaan pakan ternak baik dari segi kualitas maupun kuantitas. Pemanfaatan Limbah jerami padi menggunakan bioteknologi fermentasi untuk pakan ternak ruminansia (sapi, kambing/domba) perlu terus dikembangkan, karena dengan fermentasi dapat meningkatkan kualitas nutrisi pakan ternak, dan memanfatkan limbah hasil pertanian menjadi berdaya guna sehingga tidak terbuang begitu saja, dan bisa digunakan dalam jangka waktu yang lama untuk ketersediaan pakan ternak pada saat musim kemarau atau disaat hijauan sudah mulai berkurang. Target dari Program Pengabdian Desa Binaan yaitu bersama dengan pemerintah Desa Kalibendo melakukan pemberdayaan petani-peternak dalam pengolahan pakan ternak fermentasi, sehingga dapat mewujudkan kemandirian dan kesejahteraan peternak.Abstract: Lumajang Regency has extensive agricultural and plantation land, especially rice, corn, and coffee crops, a lot of waste that has not been utilized. Starting from the KKN program, regional potential in Kalibendo Village, Pasirian District, Lumajang Regency is very potential to be developed, one of which is Biotechnology for fermented rice straw with high nutrition, to increase the independence and welfare of breeders in Kalibendo village, Pasiria district, Lumajang Regency. Assistance from educational institutions related to quality feed processing biotechnology independently from existing local raw materials from local agricultural waste can meet animal feed availability in terms of quality and quantity. Utilization of rice straw waste uses biotechnology for ruminant animal feed (cows, goats/sheep), it needs to be continuously developed because fermentation can improve the nutritional quality of animal feed, and utilize agricultural waste to be efficient so that it is not wasted, and can be used in a long period for the availability of fodder during the dry season when the forage has diminished. The Assisted Village Service Program's target is to collaborate with the Kalibendo Village government to empower farmers in the processing of fermented feed so that they can realize the independence and welfare of the breeders.

The availability of ruminant feed in terms of amount and nutritional adequacy is a common problem during the dry season. This condition is worst at the peak of the dry season (July - October) such as that faced by the Kelompok Tani Rukun Binantu of Rejosari in Bantul Regency - Yogyakarta. Pre-survey shows that the cost of feed in the dry season is uncompetitive to the price of cattle. This problem was solved by Program Kemitraan Masyarakat (PKM – UNS) 2020 with workshop in cattle feed preservation using silage and fermentation techniques. The silage technique is used in conventional-local forage, while the fermentation technique is aimed at preserving low-nutrient animal feed as well as improving digestibility and nutritional adequacy of the feed. Product’s monitoring and evaluation are carried out after 7 days for fermentation technique and 21 days for silage technique. The program is success in solving of Mitra’s problems and it is also one of Tri Dharma Perguruan Tinggi in technology transfer for rural communities.

AbstractMost of the commercial ruminant feeds comprise Corn meal, Groundnut cake, Maize etc., which contain anti-nutritional factors called Phytates. They have high binding affinity to cationic minerals. This results in decrease in activity of the cattle by making minerals unavailable for absorption in the intestine. Many of the feed industries add Phytase enzyme that degrades the Phytic acid. Addition of Phytase enzyme is very complex method and increases the cost of the feed. If Phytase is not added, Phytic acid enters the ecosystem through the dung and due to microbial degradation, the Phytic acid gets converted into Phosphates. Phosphate abundance in water bodies leads to Eutrophication, which is a serious ecological issue. And also, in many parts of the country, post-harvest Paddy straw is burnt unused. This intentional stubble burning causes air pollution. We combined paddy straw and Azolla along with jaggery to prepare animal feed supplement. The feed pellets were evaluated for their nutritional composition and efficacy. The efficacy of the developed feed was evaluated by feeding it to milch cows and compared with regular feed for a period of 15 days. The Azolla-Hay feed improved the milk yield and also quality of the milk in comparison to the control group. This study revealed that Azolla in combination with paddy straw powder can be low-cost feed alternative especially during the lean period where the availability of feed is scarce.

Rice straw open burning is the most common form of agricultural by-product treatment in developing countries. Contaminated pollutants pollute the environment, badly affect human's health and contribute to the increase of greenhouse gases that impact climate change. This research was carried out to estimate the amount of rice straw produced, a seasonal burning rate and the modified combustion efficiency (MCE) from field-based rice straw open burning by field sampling method, field survey and quick measurement; the inventory is based on emission factors. The results show that 62% of respondents use rice straw for different purposes such as cattle feed, selling, composting... 38% respondents do not use for any purposes. The main disposal method is open burning. Open burning rate is different in each cultivative season. It was 36.36%, in winter-spring crop,  49.32% in summer-autumn crop and 40% in winter-autumn crop. In 2017, total CO2 emissions from open burning were the highest compared with two other pollutants. It was nearly 5.7 million tons and followed by CO with 135.1 thousand tons. The other pollutants emitted from open burning were PM2.5 (50.4 thousand tons), PM10 (14.4 thousand tons), SO2 (7.78 thousand tons), NO2 (0.27 thousand tons) per year. The inventory results show that rice straw open burning in An Giang has been affecting on the quality of the air environment, landscape and reducing the traffic vision; especially fine dust (PM2.5) greatly affects to local people’s health. If all surplus rice straw is used for energy production, it can help not only reduce fossil fuel use, but also reduce the amount of pollutants generated by open burning. This is a win-win solution that should be paid attention by the local authorities to come up with appropriate incentives. Keywords: emission inventory; rice straw; open burning; emissions.

This paper presents economic analysis, viability and trade-off issues for small-scale (family) inland capture fisheries in three fishing communities, each representing a distinct floodplain characteristic in Cambodia. The average net profits of family fishing was US$12 and US$4.6 per trip during the open (October to May) and close (June to September) seasons, respectively; but real profit—deducting the cost for family labour from net profit—was only US$4.5 and US$1.6 during the open and close seasons, respectively. The return from family fishing varied greatly across sites surveyed, depending on the quality of the fishing grounds, hydro-ecology settings, local institutions, and socio-economic factors. The high degree of seasonality, the spatial variation of returns and costs of capture fisheries suggest interdependence of fishing activities with basin-level water allocation policies, and also related trade-off in the fisheries sector with water allocation and water resources management policies. There is also now an urgent need for synergy of the various rural development efforts with that of fisheries policies in the Mekong River Basin.
