Abstract

Terbatasnya stok serbuk gergaji kayu sengon sebagai bahan baku baglog dapat mempengaruhi kelangsungan produksi jamur kuping (Auricularia auricula). Pemanfaatan limbah pertanian sebagai bahan baku alternatif baglog jamur kuping belum banyak diungkap. Ketiga jenis limbah pertanian yang tersedia melimpah di dataran rendah, yaitu jerami padi (PJP), potongan ampas tebu (PAT) dan serbuk gergaji kayu kelapa (SKK). Peforma pertumbuhan dan hasil panen jamur kuping pada ketiga jenis limbah pertanian tersebut yang dikombinasikan dengan dedak  (0, 5, 10 dan 15%) diinvestigasi pada penelitian ini. Serbuk kayu sengon (SKS) digunakan sebagai kontrol. Hasil menunjukkan bahwa waktu tercepat miselium penuh, pembentukan pinhead dan panen pertama dicapai berturut-turut pada hari ke-17-20, 29-32, dan 39-40 inkubasi oleh baglog SKK. Pengamatan pada hasil panen menunjukkan PJP adalah substrat terbaik dibanding SKS (sebagai substrat kontrol), SKK dan PAT. Sebaliknya, peningkatan konsentrasi dedak berdampak negatif pada hasil panen baglog PJP. Performa hasil panen terbaik diperoleh pada baglog PJP dengan dedak 0 % yaitu 13,67 g (berat basah) dengan berat baglog 240 g (berat basah). Hasil ini lebih tinggi 64,11 % dari hasil panen baglog SKS dengan dedak 5-10%. Pada akhirnya, hasil studi ini merekomendasikan PJP sebagai substrat alternatif pengganti SKS.

Abstract

Legumes are cultivated plants that are widely used by the community. In central Kalimantan, especially in Palangka Raya city, the legume is planted by the community as a garden plant which is consumed daily. The condition of acidic peatlands in Central Kalimantan is a limiting factor for plant growth. This study aims to determine the effect of peat water from the Sabangau River in Central Kalimantan on the germination of legume plants. The study used 4 (four) types of plants such as Vigna radiata L, Vigna unguiculata L, Phaseolus vulgaris L, and Glycine max L using a Completely Randomized Design (CRD). The plant seeds were first soaked in peat water for 3 (three) hours, then transferred to a medium covered with cotton and watered using the same water. Observations were made from the first day to the seventh day. The results showed that 3 (three) types of plants such as Vigna radiata L, Vigna unguiculata L, and Phaseolus vulgaris L were able to grow using peat water as a medium, while soybeans could not germinate. The results show that out of these three types of plants, Vigna radiata L has a better growth rate than Vigna unguiculata L and Phaseolus vulgaris L. Statistical tests using ANOVA analysis showed no significant differences between the three types of plants that grow.

Abstract

The Nyaru Menteng Arboretum area in Central Kalimantan serves as a habitat for approximately 200 Long-Tailed Macaques Macaca fascicularis within its 65.2-hectare area, as recorded in 2024. A lack of food causes presumed M. fascicularis to descend to settlements in search of food, resulting in losses for the people of Nyaru Menteng Arboretum which leads to coexistence. This study aims to identify the types of coexistences that occur between M. fascicularis and villagers. The method used to identify coexistences is a survey method. The survey results explain that the types of coexistences that occur range from stealing side dishes (25%), damaging ceilings (25%) and messing up the kitchen (50%). Human resistance in the form of repellent using slingshots 32%, wood 40%, nets 20% and air rifles 8%. The findings of this study can serve as a reference for managing future coexistences and inform decision-making for effective M. fascicularis management in the Menteng Arboretum Area, Central Kalimantan.   Keywords: Endangered, Indonesian Borneo, interaction, Long-Tailed Monkey, Macaca fascicularis.

Abstract

Ramin (Gonystylus bancanus (Miq) Kurz) is a peat swamp plant with commercial value in both national and international markets. However, the existence of ramin is threatened with extinction, due to the imbalance between regrowth and utilization, making it increasingly difficult to obtain ramin seedlings naturally. One of the efforts to propagate ramin is by cuttings. This study aimed to determine the optimum concentration of IBA (Indole Butyric Acid) growth regulator used in supporting the growth of ramin cuttings. The research method used a Randomized Group Design (RGD) consisting of 4 treatments and 6 replicates. The treatment consisted of P0 (control/0 ppm), P1 (IBA concentration 1000 ppm), and P3 (IBA concentration 1500 ppm). The data were analyzed descriptively qualitatively. The results showed that the provision of IBA affects the growth of ramin cuttings. Based on the percentage of cuttings that successfully grew, P0 successfully grew by 50%, P1 successfully grew by 83.33%, P2 successfully grew by 100% and P3 successfully grew by 100%. The average number of shoots of ramin cuttings that successfully grew in the treatment of P0 amounted to 0, P1 treatment amounted to 1, then P2 amounted to 2, and the highest number of shoots was in the treatment of P3 with 3 shoots. It can be concluded that the concentration of IBA 2000 ppm gives the best results when compared to other concentrations based on the percentage of cuttings that managed to grow and the average number of shoots.
