Paddy gogo is one type of non-irrigated paddy that can grow on limited inputs, one of which is the problem of water availability. Paddy gogo can grow on various types of soil, including sub-optimal land in Wamena. It is said to be sub-optimal considering the ability of the soil in the study area is a type of soil with very low nutrient content. This study aims to determine the effect of the use of NASA organic liquid fertilizer on the growth and yield of 5 varieties of upland rice plants that were tested in the sub-optimal land of Wamena. This research was conducted in March-August 2019. The study was arranged in factorial research design, namely 5 types of varieties as factor 1 (variety of Inpago Unsoed 1, Inpago Unsoed Parimas, Inpari 28, Inpago 9 and one type of Local varieties as Comparator) and the concentration of NASA liquid organic fertilizer as a second factor (150 ml/plot). The results showed that the best growth was shown by varieties Local of Wamena (Moai) with the highest appearance of plant height and Inpago Unsoed 1 varieties which showed a large number of producing offspring. When viewed from physiological and production parameters, Inpago 9 variety shows the highest leaf area index and grain weight per clump. Furthermore, Wamena Local variety showed the highest value of stomata density, Inpago Unsoed Parimas variety showed the highest total chlorophyll value and Inpago Inpari 28 variety was the producer of the highest weight value of 1000 seeds.Keywords: Liquid Organic Fertilizer; Paddy Gogo; Sub-optimal land

Wamena is one of the areas with the potential to develop a wide variety of food crops and plantations in large and medium quantities because it is supported by its natural conditions. Wamena, especially throughout Jayawijaya Regency and even other Regencies in the Central Highlands of Papua, are known for their organic farming. In order to support and maintain the productivity of organic farming systems, as an academic activist in the agricultural sector, it is necessary to conduct training on making organic fertilizer through the use of banana weevils known as Local Microorganism Fertilizer (MoL). This training was based on observations of farmer groups in the Wesaput district, where all farmers in the farmer groups had never used organic liquid fertilizers or inorganic fertilizers as additional nutrients to increase the growth and production of their agricultural products. Therefore we try to provide understanding and approaches to farmer groups through community service on how to make Local Microorganism Liquid Fertilizer in order to increase the yields of local farmers in the Wesaput District, especially the village of Kama. As a result of this activity, we saw that the farmer group community in Wesaput gave a good response so they asked for similar activities to be carried out again so that the farmer group community was more independent in making and using liquid organic fertilizer using the natural resources around them.

Jenis sumber hara selain bersumber dari pupuk yang telah dikenal secara umum, juga dapat bersumber dari pemanfaatan mikroorganisme lokal yang dibuat dari limbah buah, nanas, sayur ataupun batang pisang. Penelitian bertujuan untuk mengetahui perbandingan efektivitas penggunaan MOL nanas dan batang pisang pada budidaya jagung manis di Wamena. Penelitian terdiri dari dua percobaan yang dilakukan terpisah yaitu aplikasi MOL nanas dan aplikasi MOL batang pisang. Masing-masing percobaan menggunakan rancangan acak lengkap (RAL) yang terdiri dari 5 taraf konsentrasi MOL, yaitu kontrol (tanpa MOL), konsentrasi 100 mL L-1, 150 mL L-1, 200 mL L-1 dan 250 mL L-1. Masing-masing perlakuan terdiri dari tiga ulangan sehingga setiap percobaan terdiri atas 15 satuan percobaan. Hasil penelitian menunjukkan efektivitas penggunaan MOL batang pisang dibandingkan MOL nanas, yang ditunjukkan pada tinggi tanaman, berat kering akar, luas daun dan laju pertumbuhan nisbi serta bobot segar tongkol jagung manis tanpa kelobot pengamatan 8 MST.
