Spatial Autocorrelation on Public Facility Availability Index with Neighborhoods Weight Difference

Abstract. The level of regional development  is marked by high availability of public facilities, such as  education, health, economic, social facilities and their accessibility. A higher of index of public facility availability means a region can support human activities well, including the economic sector. Spatial patterns  of  public facility availability in Cianjur Regency were  analized by global and local spatial autocorrelation  based on the Moran's index and the local indicator spatial association (LISA) index, respectively. A spatial weighted matrix (wij) for Moran'I and LISA  calculated based on nearest neighbor, neighbor boundary length and neighbor distance. The result showed that differences in the spatial weighted matrix of Moran's  index does not affect the spatial pattern but they do affect the Moran's I values for nearest neighbor, neighbor boundary length and neighbor distance, at 0.30; 0.22 and 0.33, respectively. Differences in the spatial weighted matrix of LISA index showed that 97% of districts have the same scatter plot and only 3% of districts have different scatter plot. The spatial pattern type of public facility evailability in Cianjur Regency is cluster where  the nothern Cianjur cluster is in HH category and the central-southern Cianjur cluster is in the LL category.Keywords.

Karakteristik, Klasifikasi Tanah, Dan Pertumbuhan Tanaman Jati (Tectona Grandis Linn F.) Var. Unggul Nusantara Di Ciampea, Kabupaten Bogor

Teak (Tectona grandis Linn f.) produce one of the most desirable wood in the world. Nowadays, fast growing teak resulting from genetically engineered teak have been available. This study aims to look at the relationship between land characteristics and soil classification with vegetative growth of “Unggul Nusantara” varieties of teak. The study was conducted in Ciampea, Bogor Regency. Soil properties were analyzed from three profiles, while the vegetative growth of teak was measured from 2.5-3 years old teak planted on those land. The diversity of soil properties on the profiles were function of the difference of soil parent material as well as its position on the slopes. Three soil profiles of P-1, P-2, and P-3, lying from upslope to the downslope, were classified respectively as Typic Paleudalf, very fine, mix, active, isohipertermic; Typic Dystrudept, very fine, mix, active, isohipertermic; and Typic Hapludult, very fine, mix, semi-active, isohipertermic. Soil of the three profiles were capable of supporting the growth of teak varieties of “Unggul Nusantara”. The best grown plant was found on the profile P-1 in the upslope, followed by the plant on the profile P-3 in the downslope, and then the plants on land above the P-2 in the middle slope. Nevertheless, the quality of the teak harvest produced in the three profiles can be categorized as low category. Soil with lime sediment parent material that has a high pH and base saturation is able to provide better growth for plants teak varieties of “Unggul Nusantara”

Pemetaan Saluran Irigasi sebagai Upaya Penyediaan Air bagi Kebutuhan Pertanian (Studi Kasus: Desa Sindangsari, Kecamatan Ciranjang, Kabupaten Cianjur)

Irrigation Network Rehabilitation activities are the main supporting activities in the agricultural business by providing irrigation water for the realization of food sovereignty, particularly rice. Lowland rice is the principal agricultural commodity in Sindangsari village, Cianjur. More than 50 per cent of this village's rice fields are irrigated. Unfortunately the current irrigation conditions are classified as dry due to drought, thus inhibiting rice production. In addition to being dry, there are also many points of garbage accumulation that pollute the water flow and even obstruct the water flow. This activity aims at mapping the condition of irrigation canals in Sindangsari village. The irrigation channel map has been successfully prepared and approved by the Cianjur Regency Regional Planning Agency and the Ciranjang District Water Resources Management Office, so that more policies on irrigation issues in the area can be taken into consideration. Key words: irrigation, network rehabilitation, rice, rice fiel

Pemanfaatan Limbah Bonggol Jagung Menjadi Pakan Ternak (Silase) di Desa Sendangmulyo, Kecamatan Bulu, Kabupaten Rembang

Desa Sendangmulyo merupakan salah satu desa yang berada di Kecamatan Bulu Kabupaten Rembang yang terletak di perbatasan Kabupaten Blora. Salah satu komoditas pertanian yang banyak dibudidayakan di Desa Sendangmulyo adalah jagung. Akan tetapi pemanfaatan komoditas jagung ini umumnya masih terbatas pada bijinya saja, sedangkan bonggolnya dibuang dan justru menjadi permasalahan karena mencemari lingkungan. Melihat adanya permasalahan ini, kelompok KKN-T IPB Rembang mengadakan webinar sekaligus praktek pembuatan silase berbahan bonggol jagung. Tujuan program ini adalah untuk memberikan pemahaman kepada masyarakat Desa Sendangmulyo terkait pemanfaatan limbah bonggol jagung menjadi silase. Webinar dilaksanakan secara online melalui platform zoom meetings untuk masyarakat umum kemudian dilanjutkan dengan praktek pembuatan silase bersama-sama untuk masyarakat Desa Sendangmulyo. Bahan yang digunakan dalam pembuatan silase yaitu bonggol jagung dan rumput gajah yang sudah di cacah, dedak, molase, serta air. Silase yang baik dapat dilihat dari karakteristik fisik seperti warna, tekstur, aroma, dan keberadaan jamur. Berdasarkan hasil pengamatan silase yang dibuat memiliki warna cokelat terang, tidak berair dan bau yang sedikit asam tetapi masih terdapat sedikit jamur sehingga hasil silase dapat digolongkan kurang baik. Pelaksanaan webinar dan praktik secara langsung pembuatan pakan ternak silase dari bonggol jagung mendapat respon positif dari peserta webinar dan masyarakat Desa Sendangmulyo. Kekurangan dari program ini yaitu dalam pelaksanaan praktik pembuatan silase jumlah peserta terbatas karena masa PPKM sehingga penyampaian informasi belum tersampaikan secara luas
