Abstract

Buah jeruk Selayar merupakan jeruk unggulan Sulawesi Selatan yang memiliki daya simpan rendah.  Penyimpanan suhu rendah merupakan salah satu upaya untuk meningkatkan daya simpan produk hortikultura. Namun, setiap produk memiliki respon berbeda pada setiap tingkatan suhu. Penelitian ini bertujuan mempelajari suhu simpan yang tepat untuk memperpanjang daya simpan buah jeruk Selayar.  Penelitian ini menggunakan rancangan lingkungan Tersarang (Nested design) dengan perlakuan suhu simpan (suhu 18 oC, 20 oC dan suhu ruang). Hasil penelitian menunjukkan bahwa jeruk Selayar perlakuan penyimpanan suhu ruang, mengalami susut bobot dan kelunakan yang lebih tinggi dibandingkan perlakuan suhu 18 oC dan suhu 20 oC. Namun, suhu simpan (18, 20 oC dan suhu ruang) tidak berpengaruh pada kandungan gula (Total Padatan Terlarut) dan total asam tertitrasi buah jeruk selayar.

Abstract

The distribution of shelled corn in West Malangke District is dominated by intermediaries, resulting in a low farmer's share received by farmers, especially women farmers. This study aims to identify the role of women in the shelled corn distribution chain, analyze marketing margins, and evaluate the profit-to-cost efficiency of each distribution channel in West Malangke District. The results indicate four trading channels, with Channel I as the primary channel, where the highest marketing margin was recorded at IDR 325 per kg, but the lowest farmer's share was only 92.58%. Conversely, Channel IV, which eliminates the role of intermediaries, provided a farmer's share of 100%. The highest profit-to-cost ratio was achieved by village collectors in Channel I (0.68), while wholesalers had a relatively stable profit ratio across channels. These findings suggest that the shorter the distribution chain, the greater the profits received by farmers. The implications of this study emphasize the importance of shortening the distribution chain and empowering women farmers through more efficient market access, as well as the need for policies to improve trading efficiency to support farmer welfare.

Abstract

Former nickel mine lands often have low soil quality and do not support the growth of revegetation plants. This study aims to evaluate the effect of humic substances and compost on improving the quality of post-nickel mine soil and plant growth media. The experiment was conducted using a completely randomized design in a factorial pattern with three levels of humic and compost treatments, as well as a combination of both, applied to nickel post-mining soil. The results showed that the addition of compost significantly increased the cation exchange capacity (CEC) and availability of nutrients (Ca, Mg, K, Na) in the soil. The addition of humic materials had relatively no significant impact on increasing CEC, but could increase phosphorus levels in the soil. In addition, compost and the combination of compost with humic materials can reduce available heavy metal Cr, although it causes an increase in Ni heavy metal levels in the soil. The results of this study make a significant contribution to the rehabilitation of ex-mining land in a sustainable manner, especially the use of humic materials and compost as a strategy to improve soil quality and increase agricultural productivity. The use of these organic materials is proven to be effective in improving the physical, chemical and biological properties of degraded soils, so it can be a more environmentally friendly approach compared to the use of synthetic chemicals
