Peatland is an important ecosystem in Indonesia. But in almost every dry season, drained peatlands have been subject to detrimental wildfires. As a response, the government has explicitly prohibited the burning of land since 2016. To clear the land of crop residues and conduct zero burning practices, one alternative method is to utilize the waste biomass to support the cultivation of earthworms (vermiculture). This study examined the quality of liquid fertilizers and compost produced from vermiculture using a completely randomized factorial design, consisting of two treatment factors. The first factor was worm type, with two species used in this research named Lumbricus rubellus and Eudrilus eugeniae. The second factor was the type of feed provided to the worms, comprising no feed (control), vegetable waste, and crop residue waste resulting from zero burning land preparation. The type of feed significantly affected the pH value of the liquid fertilizer produced by the vermiculture but did not significantly affect the nutrient contents (N, P, and K). The combination of the types of earthworms and types of feed significantly affected the pH value of the vermicompost. The combination of worm types and feed types had a significant effect on exchangeable Ca, but not on exchangeable Mg, Na, and K. In combination, green vegetable waste and Lumbricus rubellus produced the greatest effect on soil CEC. However, for Base Saturation, the control (no food) and Eudrilus eugeniae showed the highest value. Types of worms and types of feed had a significant effect on the exchangeable Mg, while the other three parameters made no significant differences. Zero burning waste and Eudrilus eugeniae provide a better exchangeable Ca and Mg. In contrast, no-feeding and Eudrilus eugeniae have a better effect on exchangeable Na and K. Types of worms and types of feed did not significantly affect the weight of worm colonies, but the addition of feed increased the weight of worms with the highest weight resulting from the use of zero burning waste feed. The results showed that crop residue wastes were potentially good as a feed for earthworms.

Climate change that occurs in Central Kalimantan mostly caused by forest and land fire has led to season shifting and gender life order changing. Thus, it resulted in a poor impact on gender life sustainability that was difficult to be recovered in a short time. This research aims to identify and evaluate the adaptation of women to forest and land fires in Palangkaraya and to express solutions that can improve gender equality. The research was conducted in Kalampangan, Sebangau. This research applied an interview method with a purposive sampling technique and conducted a descriptive analysis that emphasized climate change conditions in recent years. Climate change caused land changing due to forest and land fire. Therefore, it was also able to change gender roles (women) to take responsibility to support family economic conditions. This condition created a double burden carried by women, so this condition required a choice of adaptation for women in dealing with it. The intended strategic choices were (1) surviving with these conditions and utilizing modest agricultural products; (2) changing land, using a traditional system while the restoration of burned land was processed; (3) forming post- fire farmer groups by gradually changing their mindset.

Climate change has the most severe impact on women, but studies on adaptation in a gender perspective are still limited. The purposes of this study were to find out: (1) gender role changes in response to climate change, and (2) the impact of gender role changes on the vulnerability of women. This study was conducted on the peat-swamp ecosystem in Pulang Pisau Regency, Central Kalimantan. Gender roles in natural resource management in adapting to climate change in the peat-swamp ecosystem were descriptively qualitatively analyzed which emphasized relations and gender roles in the household. Data were collected using structured questionnaires. This study used documentation methods with secondary data types. From the results of the study, it can be seen that the gender role of women is divided into three, namely productive roles, reproductive roles, and social community roles. Climate change in Pulang Pisau Regency will interact and be sustainable with gender inequality and which disadvantages women than men, especially among the poor community, so that access to the availability of natural resources is needed in order to solve existing vulnerabilities and increase more real participation in the current climate change adaptation process.

Tujuan penelitian ini adalah: 1) untuk mengetahui adanya interaksi antara jenis media dan jenis pakan terhadap kualitas pupuk organik cair pada kompos cacing tanah Lumbricus rubellus, 2) untuk mengetahui adanya pengaruh jenis pakan terhadap kualitas hasil pupuk organik cair dari kompos cacing tanah Lumbricus rubellus, 3) untuk mengetahui adanya pengaruh jenis media terhadap kualitas hasil pupuk organik cair pada kompos cacing tanah Lumbricus rubellus. Penelitian ini menggunakan Rancangan Acak Lengkap faktorial 4x3 dengan 3 ulangan. Faktor perlakuan pertama G1 : Pupuk Kandang Kotoran Sapi 100% (1,4 kg), G2 : Kombinasi Media Pupuk Kandang Kotoran Sapi 50% (0,7 kg) dengan Tanah Gambut faktor perlakuan kedua P1 : Ampas Tahu = 150 g, P2 : Rumen Sapi = 100 g. Parameter pengamatan yang digunakan yaitu Bobot akhir cacing, pH, NO3, NO2, P, K, NH3 dan N. Hasil yang didapatkan adanya interaksi antara jenis media dan pakan terhadap kualitas pupuk organik cair pada kompos cacing tanah Lumbricus rubellus terhadap parameter bobot akhir cacing tanah Lumbricus rubellus dengan kombinasi terbaik terdapat pada perlakuan kombinasi media pupuk kandang kotoran sapi dengan tanah gambut (155,77 gram) dan pada parameter pH. Terdapat pengaruh yang nyata pada jenis media terhadap kualitas hasil pupuk organik cair pada kompos cacing tanah Lumbricus rubellus tehadap parameter K faktor tunggal perlakuan kombinasi media pupuk kandang kotoran sapi (269,23 mg/l) dan terhadap parameter suhu dipagi hari pada faktor tunggal perlakuan kombinasi media pupuk kandang kotoran sapi dengan tanah gambut (26,50 oC), dan siang hari terdapat pada faktor tunggal perlakuan media kombinasi media pupuk kandang kotoran sapi dengan tanah gambut (29,26 oC). Sedangkan yang tidak berpengaruh nyata terhadap parameter senyawa NO3, senyawa NO2, unsur P, senyawa NH3, dan unsur N. Terdapat pengaruh yang nyata pada jenis pakan terhadap kualitas hasil pupuk organik cair dari kompos cacing tanah Lumbricus rubellus terhadap parameter suhu dipagi hari pada faktor tunggal perlakuan pakan rumen sapi (26,51oC).

This research aims to determine the effect of the application Vermicompost Organic Fertilizer and NPK inorganic fertilizer in different doses to see mustard plants' growth and the yield on the media of inland peat soil. The study was a completely randomized design factorial Completely Randomized Design, consisting of 2 treatment factors and three replications. The first factor is the dose of Vermicompost organic fertilizer (D), which consisting of 3 levels i,e D0 : control ; D1: 100 g/polybag; D2 : 200 g/polybag and the second factor is the dose NPK Fertilizer which consisting of 2 levels M0: control; M1: 1 g/polibag. This research has been conducted on the experimental field department of agriculture cultivation, Faculty of Agriculture, Palangka Raya University, Palangka Raya City, Central Kalimantan from October until December 2017. The results showed that the interaction of Vermicompost organic fertilizer and NPK fertilizer did not give an effect for plant growth parameters. Doses Vermicompost 100 g / polybag and NPK 1 g / polybag gave the highest results to growth and yield of mustard plants; based on the results of the analysis, the treatment of 1 g NPK / polybag had a very significant effect on the observed parameters such as plant height, number of leaf, root weight, and total plant weight.
