Abstract: The establishment of educational tourism in mangrove areas is expected to prevent and overcome the impact of tourist activities on nature and culture. This community service activity was carried out in the Tanjung Batu Mangrove area, Sekotong Village with the aim of designing an educational tourism concept to maximize the use of mangroves as a new tourist attraction in the Central Sekotong area. The selection of mangrove locations was carried out by purposive sampling, and the methods applied to this service were observation, socialization, discussion and direct area arrangement. The results of observations showed the potential flora in Tanjung Batu, namely Rhizophora mucronata, Rhizophora stylosa and Avicennia lanata. Meanwhile, the birds types found in this area are terns, swallows, black eagles, sparrows, king prawns and Asian plover. The potential of flora and fauna is then described in the Flora-Fauna interpretation board and a short documentary related to the area which was prepared jointly by the manager and the community service team. Recommendations for the types of educational tourism activities that can be offered for the Tanjung Batu Mangrove area, namely bird watching, mangrove planting, canoeing, and making mangrove films. Keywords: Mangrove, Tanjung Batu, Educational tourism

[Bahasa]: Kawasan Hutan Pendidikan Senaru atau disebut juga dengan Kawasan Hutan dengan Tujuan Khusus (KHDTK) Senaru memiliki potensi multi fungsi yang dapat memberikan manfaat ekonomi, lingkungan, pendidikan dan sosial bagi umat manusia. Manfaat tersebut diantaranya berasal dari Hasil Hutan Kayu (HHK) dan Hasil Hutan Bukan Kayu. Selain manfaat yang bersumber dari HHK dan HHBK terdapat juga manfaat jasa lingkungan seperti wisata alam dan pendidikan. Dalam perjalanannya KHDTK Senaru dimanfaatkan sebagai tempat wisata bagi masyarakat baik lokal, nasional maupun internasional yang datang ke KHDTK Senaru untuk menikmati pemandang alamnya atau melewati KHDTK untuk melanjutkan perjalanan mereka menuju puncak Gunung Rinjani. Kondisi ini tentunya merupakan perkembangan yang positif bagi KHDTK Senaru dan pengelola, dalam melakukan pengembangan wisata kedepannya. Permasalahan yang terjadi pada saat ini yaitu belum maskimalnya informasi terkait sumberdaya hutan yang ada pada KHDTK Senaru untuk menunjang wisata edukasi bagi pengunjung maupun masyarakat sekitar terkait dengan alam sekitar, terutama pengenalan jenis vegetasi yang terdapat disepanjang jalur wisata. Sehingga tujuan dilaksanakannya kegiatan pengabdian ini adalah: (1) untuk menyediakan informasi vegetasi yang terdapat pada jalur wisata, (2). menyediakan herbarium vegetasi yang ada sepanjang jalur dan (3) menyediakan papan informasi terkait vegetasi pada jalur wisata. Motode yang digunakan adalah observasi, focus group discussion (FGD), dan sosialisasi. Adapun hasil yang diperoleh adalah sebagai berikut: (1) masyarakat memiliki data terkait jenis-jenis vegetasi yang terdapat pada jalur-jalur wisata, (2) tersedianya herbarium jenis-jenis vegetasi yang ada di sepanjang jalur (3) tersedianya papan informasi terkait jenis-jenis vegetasi yang ada di sepanjang jalur. Kata Kunci: KHDTK; Senaru; wisata edukasi; pengenalan jenis vegetasi [English]: Senaru Educational Forest or also known as Forest Area with Special Purposes (KHDTK) has a multi-functional potency that can provide economic, environmental, educational, and social benefits for people. The benefits are derived from Timber Forest Products (HHK) and Non-Timber Forest Products (HHBK). In addition, there are also benefits from environmental services such as natural tourism and education. KHDTK Senaru is used as a tourist destination ranging from local, national and international tourists who came to enjoy its natural views or pass through to the summit of Mount Rinjani. This condition is certainly a positive development for KHDTK Senaru and the management, in carrying out tourism development in the future. The current problem is the lack of information regarding the forest resources available at the KHDTK Senaru to support educational tourism and the local communities regarding the natural environment, especially the introduction of vegetation species along the tracks. Thus, the aims of this community service program are (1) to provide information on vegetation available along the tourist track, (2) to provide herbariums for vegetation along the tourist track, and (3) to provide information boards related to vegetation available on the tourist track. The methods used are observation, focus group discussion (FGD), and socialization. The results obtained after the program are as follows: (1) the local communities have database regarding list of vegetation species available along the tourist tracks, (2) the availability of herbariums of vegetation on the tourist track, and (3) the availability of information boards of vegetation at the tourist track.

This study aimed to investigate the physical and chemical characteristics of the soil based on the type of land management in the production forest in Banyu Urip Village, Central Lombok. Determination of the sampling point is done by employing stratified random sampling. The sampling points were 22, divided into two types of land: forest land (dominated by MPTS plants and woody plants) and agricultural land (dominated by seasonal plants). Soil samples were taken with two depths, namely 0-10 cm and 10-20 cm. Soil samples taken were disturbed and undisturbed soil with variables of physical properties (texture, bulk density, porosity, and color) and soil chemistry (C-organic). The research results on the physical properties of the soil showed that the soil texture in both types of land was dominated by dusty clay. The average porosity value in agricultural land is 49.33%, and forest land is 49.48% (unfavorable category). The average bulk density value in forest land is 1.39 g/cm3 and in agricultural land is 1.35 g/cm^3 (high category). The soil color of the two land types is dominated by dark brown. The average value of C-organic soil is 1.80% in forest land and 1.72% in agricultural land (low category).

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.
