Beras hitam merupakan varietas lokal yang mengandung pigmen paling baik, memiliki rasa dan aroma yang baik dengan penampilan yang spesifik dan unik. Beras hitam masih jarang dibudidayakan dan dikonsumsi oleh masyarakat dikarenakan banyak masyarakat yang belum familiar tentang beras hitam, umur tanam padi hitam yang lebih panjang dibandingkan padi putih (bisa mencapai 5-6 bulan), dan produktivitasnya yang lebih rendah dibandingkan padi putih. Salah satu upaya yang dapat dilakukan untuk meningkatkan kuantitas padi hitam adalah dengan pemupukan, baik organik maupun anorganik. Penelitian ini bertujuan untuk mengidentifikasi jenis dan taraf pupuk organik terbaik yang didapatkan dari pupuk kandang untuk dapat meningkatkan pertumbuhan dan hasil beras hitam. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) 2 faktor yaitu jenis pupuk kandang dan taraf pupuk kandang. Pupuk kandang yang digunakan yaitu pupuk kandang ayam, pupuk kandang sapi, dan pupuk kandang kambing. Taraf pupuk kandang yang digunakan adalah 0% (0 g), 50% (6,25 g), 100% (12,5 g), 150% (18,75 g), 200% (25 g), dan 250% (31,25 g) dengan tiga ulangan. Perlakuan pupuk kandang kambing sebanyak 18,75 g mampu meningkatkan kandungan klorofil hingga 2,67 mg/g.

The waste heap of Banyuwangi Regency in 2019 was ± 3,387 m3/day with an increasing trend over the last 10 years. It came from settlements, markets, parks, drainage, and other places, which only part of it could be transported to the landfill due to the declining capacity of the landfill. In addition, waste management services mostly only cover urban areas, while in rural areas are usually carried out on-site by people as did in Gitik Village, Rogojampi District. Waste management did traditionally and partly subscribing to waste transport services. Waste transported by the service is only dumped with an open dumping way, due to the unavailability of landfil facilities in Gitik Village. The existence of waste transport services has not been utilized by all the rural people, because some of them were constrained by the cost of waste service fees. As a result, many piles of household waste are still found in various places that cause environmental pollution. The most common complaint felt by the people regarding the impact of pollution is the pungent smell of waste which usually comes from household organic waste. The solution that can be done to overcome these problems is to process household organic waste into eco-enzymes. The eco-enzyme produced from this program can be used by people for many household activities including farming. In addition, environmental cleanliness can also be improved by reducing the amount of household organic waste that is disposed of around settlements.

The negative impact of chemical fertilizers use is soil fertility declining. The situation occurs because of biological, physical, and chemical properties of the soil is decreased. Agricultural waste is a large commodity which utilization can still be optimized, for example by using as raw material for organic liquid fertilizer. Agricultural wastes that have good quality as fertilizer include goat manure, chicken excreta, and coconut husk. The utilization of agricultural waste as organic fertilizer is one way of creating sustainable agriculture. This study aims to test the quality of liquid fertilizer (bioculture) of goat manure and chicken excreta by adding various levels of coconut husk. Bioculture is made by anaerobic fermentation for 21 days. The parameters observed included levels of C-organic, N, P, and K bioculture, as well as germination tests to determine the presence of phytotoxins. The data were analyzed using one way ANOVA. The treatment of P5 (5% coconut husk) showed the highest levels of N and P, while the K content was not significantly different from the treatment of P4 (2.5% coconut husk). The germination test showed no phytotoxin activity in bioculture.

Indonesia is an agricultural country that certainly has the potential for agricultural waste and by-products. Some of those in Indonesia are livestock manure, coconut husk, and sugarcane molasses. Utilization of this waste is limited, which is causing various environmental problems such as environmental pollution. The study is aimed to determine the quality of organic liquid fertilizer made by raw material from goat feces-chicken excreta-coconut husk with various sugarcane molasses concentrations (P0= 0%; P1= 5%; P3= 15%; P4= 20%; P5= 25%). The fermentation was carried out anaerobically for 21 days. The parameters of temperature, pH, organoleptic (color and odor), levels of C-organic, nitrogen (N) total, phosphorus (P) total, potassium (K) total, and biological tests were observed. Biological tests were conducted in the growth of mung bean (Vigna radiata) and spinach (Amaranthus tricolor). Data were analyzed using one-way ANOVA. Variations in the addition of molasses sugarcane did not affect the liquid fertilizer's temperature and pH during fermentation. However, the treatments had positive effect on organoleptic test, C-organic, N total, P total, K total, and biological tests. The addition of 15% sugarcane molasses (P3) showed a dominating performance toward most of the parameters tested. The P3 treatment produced liquid fertilizer with a pleasant smell, and the contents of C-organic, total N, total P, and total K were 2.12%, 0.25%, 0.13%, and 0.13%,  respectively. and produce spinach as a biological test with plant height, number of leaves, leaf width, stem diameter, and root length were 21.82 cm, 6.66 sheets, 3.59 cm, 4.09 mm, and 14.67 cm, respectively.

Rumah Kopi Ibu Bumi merupakan usaha kopi rumahan yang mengolah kopi sangrai dan produk seduhan kopi. Metode seduhan kopi di Rumah Kopi Ibu Bumi selama ini kurang praktis, menghasilkan body kopi yang tebal, pekat, produk relatif mahal, dan hanya bisa dinikmati dalam satu kali porsi. Hal ini membuat proses menyeduh kopi menjadi tidak efisien waktu dan kurang ekonomis. Metode cold brew menggunakan drip bag coffee memungkinkan untuk mengatasi permasalahan ini. Metode ini menghasilkan seduhan kopi yang lebih rendah kafein, dapat digunakan untuk beberapa kali seduh, dan produk lebih terjangkau. Kegiatan ini menghasilkan produk kemasan kopi decaf dalam drip bag yang siap dipasarkan.
