Abstract

Asian palmyra palm (lontar) fronds are a byproduct generated from the asian palmyra palm plant. To add value to these fronds, they can be converted into activated charcoal. This study aims to determine the properties of activated charcoal derived from asian palmyra palm fronds and the effects of activation temperature and chemical concentration on these properties. The activation process was conducted using H3PO4 solution with two concentration variations, 10% and 20%, for 24 hours, and three temperature variations, 600°C, 700°C, and 800°C, each for 60 minutes. The data obtained were analyzed using R software version 4.3.1. The effects of the variation factors in H3PO4 concentration and activation temperature on the yield and characteristics of the activated charcoal were calculated using two-way ANOVA with a 95% confidence level. The properties of the activated charcoal produced met the SNI 06-3730-1995 standard for technical activated charcoal, with yield, moisture content, ash content, volatile matter content, fixed carbon content, and iodine adsorption values of 80.41%, 0.42%, 9.35%, 8.28%, 82.38%, and 668.13 mg/g, respectively. The best properties of activated charcoal were obtained from the activation treatment at 600°C and 20% H3PO4 concentration

Abstract

In Bayan Village, West Nusa Tenggara, there are four customary forest areas that have the potential to be developed through the Customary Forest scheme. This scheme is part of the Social Forestry Program which provides access and forest management rights to indigenous communities. The four forests are currently being managed by the indigenous peoples but have not yet been granted the status of customary forest. The aim of this study is to evaluate the potential of the Bayan indigenous community to acquire forest management rights under the Customary Forest scheme. The research employed a normative-empirical approach. The results indicate that the Bayan indigenous peoples meets all the criteria in the Government Regulation No. 23 of 2021 on the Implementation of Forestry and the Ministry of Environment and Forestry Regulation No. 9 of 2021 on Social Forestry Management. The Bayan indigenous peoples is eligible to be designated as a Customary Law Community by the Regent of North Lombok and to obtain Customary Forest management rights from the Ministry of Environment and Forestry. This potential is supported by two factors: (1) the potential for forest and tourism development; and (2) the potential for well-maintained local wisdom.

Abstract

Water quality is a condition that indicates the quality of water in a body of water, water sources and river basins. Water quality requires testing and analysis by considering its physical conditions, chemical content, and biology. Aik Nyet natural tourist attraction is one of the famous water sources in the Lombok area, West Nusa Tenggara. Bathing and swimming activities in this area can potentially cause pollution of water quality, but until now there has been no information regarding the quality of water in this natural tourist attraction. Therefore, this study aims to analyze the quality of water in the Aik Nyet Natural Tourist Attraction, Sesaot Resort, KPHL Rinjani Barat, Lombok. Water quality is assessed using Class Two water quality standards in accordance with the Decree of the Minister of Environment No. 115 of 2003, alongside identification using the US Environmental Protection Agency (US-EPA) system. Sampling was performed at three distinct points to analyze physical, chemical, and biological parameters. The results of the analysis showed that several parameters such as temperature, pH, ammonia levels, and the number of E. coli bacteria met the quality standards, while the chemical parameters DO and BOD showed mild pollution

Abstract

Bamboo is a very abundant resource with high diversity. There are 157 types of bamboo in Indonesia, one of which is petung bamboo. Petung bamboo is used as raw material for handicrafts and construction, but much of it remains unused and becomes waste, making it a potential alternative fuel source such as bio-briquettes. This study aims to determine the effect of compression pressure on the characteristics of petung bamboo charcoal briquettes and to determine the suitability of the quality of petung bamboo charcoal briquettes according to SNI 01-6235-2000. The research design used was a non-factorial completely randomized design (CRD) with compression pressure factors consisting of 200 psi, 350 psi, and 500 psi. The conversion of bamboo biomass into charcoal was carried out using the pyrolysis method with a drum kiln. The results showed that the highest average density value was found in treatment T3, which was 0.53 g/cm3, while the lowest average density value of charcoal briquettes was found in treatment T1, which was 0.44 g/cm3. Based on SNI, the moisture content that met the SNI standard was found in treatment T2 (350 psi) < 8%. The ash content of all treatments of charcoal briquettes meets the standard of < 8%, the volatile matter content of all treatments of charcoal briquettes does not meet the standard of <15%, and the calorific value of all treatments of charcoal briquettes meets the standard of > 5000 cal/g. Compression pressure does not affect the characteristics of petung bamboo charcoal briquettes. All characteristics of petung bamboo charcoal briquettes in this study met the SNI No. 01-623-2000 standard, except for the volatile matter content and moisture content at pressures T1 (200 psi) and T2 (350 psi).

Abstract

Penelitian ini bertujuan untuk mengevaluasi kondisi kelembagaan ekowisata berbasis masyarakat di Deswita Non Pendakian Savana Propok Resort Aikmel, Taman Nasional Gunung Rinjani, serta merumuskan strategi penguatan kelembagaan yang berkelanjutan. Pendekatan yang digunakan adalah Institutional Development Framework (IDF) untuk menilai tingkat efektivitas kelembagaan melalui lima dimensi utama, yaitu ekologi, ekonomi, sosial budaya, tata kelola, dan pengalaman wisatawan. Selain itu, analisis SWOT diterapkan untuk mengidentifikasi kekuatan, kelemahan, peluang, dan ancaman dalam pengelolaan ekowisata sebagai dasar perumusan strategi penguatan. Data penelitian diperoleh melalui observasi langsung di lapangan dan wawancara mendalam dengan tiga kelompok responden utama, yaitu pihak pemerintah, pengelola lokal, dan wisatawan. Hasil analisis menunjukkan bahwa nilai indeks IDF gabungan sebesar 1,6, yang menempatkan kelembagaan pada kategori “berkembang”. Pemerintah dan pengelola menilai kelembagaan telah menunjukkan arah menuju tahap pemantapan, sementara wisatawan menilai masih terdapat kekurangan terutama pada aspek fasilitas dan pelayanan wisata. Berdasarkan hasil analisis SWOT, strategi prioritas diarahkan pada peningkatan koordinasi antarlembaga, penguatan kapasitas sumber daya manusia, perluasan jaringan kemitraan eksternal, dan optimalisasi promosi digital berbasis komunitas. Hasil kajian ini menegaskan pentingnya sinergi antara pemerintah, masyarakat, dan pihak swasta dalam memperkuat kelembagaan ekowisata agar mampu berkembang secara adaptif, berdaya saing, dan berkelanjutan serta memberikan manfaat ekonomi dan sosial bagi masyarakat lokal. Analisis data dalam penelitian ini juga menggunakan pendekatan deskriptif kualitatif melalui triangulasi antara hasil observasi, wawancara, dan dokumentasi untuk memastikan keabsahan data. Temuan penelitian memberikan implikasi praktis bagi pengelola dan pemerintah dalam memperkuat koordinasi kelembagaan, meningkatkan kapasitas SDM, serta memperluas jejaring kemitraan. Namun, penelitian ini memiliki keterbatasan pada jumlah responden dan cakupan lokasi yang relatif terbatas, sehingga disarankan adanya penelitian lanjutan dengan pendekatan kuantitatif untuk memperkuat hasil evaluasi kelembagaan.

Abstract

Bamboo is an environmentally friendly construction material because it is renewable, lightweight, and possesses good mechanical strength. However, due to the lack of basic knowledge about the properties of bamboo culms, only a few species are commonly utililized. This study aims to investigate the longitudinal variation of physical and mechanical properties of Dendrocalamus asper and Gigantochloa apus that grow naturally on Lombok Island. Sampling was carried out by selecting 10 bamboo culms, aged 3-4 years old, from different clumps at each location. The tests conducted include moisture content, basic density, tangential and radial shrinkage, modulus of elasticity (MOE), and modulus of rupture (MOR). Statistical analysis was performed using R software, incorporating linear and non-linear mixed-effects models to evaluate longitudinal variations and the influence of individual and location on the distribution of bamboo properties. The results showed that the values for green moisture content, basic density, tangential and radial shrinkage at 1% moisture content change, MOE, and MOR for G. apus were 99.97%, 0.60 g/cm³, 0.29%, 0.35%, 8.27 GPa, and 108.80 MPa, respectively. Meanwhile, the values for D. apser were 108.13%, 0.58 g/cm³, 0.34%, 0.42%, 9.71 GPa, and 102.47 MPa, respectively. The longitudinal variation of moisture content in G. apus followed a linear pattern, while a logarithmic equation best described the variation in moisture content of D. asper, basic density, MOE, and MOR for both bamboo species. Additionally, the longitudinal variation in tangential and radial shrinkage for both species remained constant, following a linear equation with a y-intercept.

Abstract

Patchouli plant (Pogostemon cablin Benth.) is one of the essential oil producing plants that is useful in the fields of pharmaceutical, cosmetics and perfume as a mixture or fixation (binding of fragrances). The success rate of patchouli early growth, is largely determined by the cultivation techniques used, one of which includes vegetative cultivation of various selected stem cutting, and planting media. This study aims to determine the effect of material from cuttings and planting media on the growth of patchouli plants. The research was conducted at the Greenhouse of the University of Mataram Forestry Study Program, using a Factorial Completely Randomized Design (FCRD). The first factor is various stem cutting with three levels, namely tip stem cuttings, middle stem cuttings and base stem cuttings and the second factor is planting media with four levels, namely forest soil media, soil:cocopeat (1:1), soil:cocopeat (1:2) and soil:cocopeat (2:1). The results showed that the effect of material from stem significantly affected the percentage of life, number of shoots, number of leaves, shoot length. For the planting media, it had a significant effect on the length of the shoot, shoot diameter, leaf area, dry trimming weight. The interaction effect of various stem cutting and plan media did not have a significant effect on the growth parameters of patchouli. The treatment of material from cuttings in patchouli plants had the best growth effect on the treatment of S2 (middle stem cuttings) and the treatment of planting media had the best growth effect on the M0 (soil media) treatment.
