Vegetables and flowers are produced under andisol and alfisol soils with elevations ranging from 350-1500 m above sea level (asl). Potatoe in Indonesia is a plant that has promosing economic value, so farmers are competing to plant the crop. Mountainous lands that were utilized into agricultural land needs to evaluate based on type of land use in order to know the potential of production and the impact of land damage that arises. This research had been conducted in Giritirta, Pejawaran, Banjarnegara, Central Java implemented on July 2017-November 2017. The method used was survei research on land quality with direct field observation, and collecting data from relevant agencies, and survei on farmer response was conducted by interview. Primary data taken was data obtained directly from the object of research through observation, interview with questionnaire, secondary data compiled were data obtained by previous researchers. The results showed that usage for agricultural in the location of the research in the form of cultivation annual crops the usable land with potatoe (Solanum tuberosum L.) as main crop and the technique of planting by aranging the slope with minimum land conservation measures. The level of erosion hazard is classified in very heavy class on all of Land Unit which causes the potential for high land degradation in a short time. The way mitigation to avoiding the damage by implementation on planting coffee arabica and tea in steep land (26%-40%) and quinine in very steep land (>40%). Land improvements made by making and repairing terraces land, strip grass and making rorak.

This research was conducted in PTPN IX Afdeling Krumput Banyumas in July 2016, with observational survey method is by field orientation, exploration, and analysis of vegetation. The data collection is done by means of interviews and direct observation. Preliminary surveys conducted to seek information from relevant agencies, environmental conditions around the rubber planting. The main survey is done to take samples of weeds in every age group, every group performed 5 times the sampling is considered to represent the age group. The variables measured were type of weed, SDR, and the coefficient Communities (C).The results showed that the weed dominant in the younger age group (1-5 years): Cyperus Kyllingia, Axonopus compressus, Clibadium Surinames, adolescent age group (6-10 years): Cyperus Kyllingia, Paspalum conjugatum Berg, Calopogonium mucuinoides Desv., Group age youth (11-15 years): Cyperus Kyllingia, Paspalum conjugatum Berg, Chromolaena odorata., adult group (16-20 years): Eleusine indica, Paspalum conjugatum Berg, Chromolaena odorata, then the dominant weeds on the slopes of the West-East direction (BT ) is Calopogonium mucuinoides Desv., Clibadium Surinames, Paspalum conjugatum Berg, and the dominant weed species in the North-South direction of the slope (US) is Calopogonium mucuinoides Desv., Paspalum conjugatum Berg., and Axonopus compressus. Weeds dominant age group and Directions Slope is Cyperus killingia and Eleusine indica (L), Paspalum conjugatum Berg, Axonopus compressus, Clibadium Surinames and Calopogonium mucuinoides Desv.

Penelitian ini dilakukan di desa Giritirta, kecamatan Pejawaran, kabupaten Banjarnegara, Jawa Tengah yang dilaksanakan pada bulan Juli 2017 - November 2017. Metode yang digunakan adalah penelitian survei terhadap kualitas lahan dengan pengamatan langsung di lapangan, dan mengumpulkan data-data dari instansi terkait, serta survei terhadap respon petani yang dilakukan dengan wawancara. Data primer yang diambil adalah data yang diperoleh secara langsung dari objek penelitian melalui kegiatan observasi, wawancara dan/atau kuisioner, sedangkan data sekunder adalah data yang diperoleh peneliti dari sumber yang sudah ada. Pemanfaatan lahan pertanian di lokasi penelitian berupa budidaya tanaman semusim dengan komoditas utama kentang (Solanum tuberosum L.) dengan teknik penanaman searah lereng serta minim tindakan konservasi lahan. Tingkat bahaya erosi tergolong dalam klas sangat berat di semua satuan lahan yang menyebabkan potensi kerusakan lahan tinggi dalam kurun waktu yang singkat. Cara mitigasi kerusakan lahan yang cocok untuk dilaksanakan yaitu dengan penanaman kopi arabika dan teh pada kelerengan curam (26%-40%) serta tanaman kina pada kelerengan sangat curam (>40%). Perbaikan lahan yang dilakukan dengan pembuatan dan perbaikan teras, penanaman strip rumput, serta pembuatan rorak
