Abstract

This study aims to test solid organic fertilizer on the growth of curly red chili. The method used is a Randomized Block Design with planting on dry land by making beds measuring 1 m x 7 m and spacing of 60 cm x 50 cm. The treatments are P1 (Giving organic fertilizer of horse manure resulting from burning), P2 (Giving organic fertilizer of cow manure), P3 (Giving organic fertilizer of chicken manure) and P4 (Giving of organic compost artificial fertilizer) repeated 3 times by giving the same fertilizer dose (18, 93 ton ha-1). Data analysis used analysis of variance (Duncan α 0.05 test). The highest crop research results were P4 and the lowest was P2. The results of the study of the growth of the number of leaves there are significant differences in the treatment of P1 to treatment P2 and P4 but do not have a significant effect on the treatment of P3. The highest average yield of chili is in P4 and the lowest is in P2. On fruit length growth shows a real influence, where P4 has the highest and lowest yield is P2. Similarly, in the growth of the number of fruits where P4 has the highest and lowest treatment P2. These results indicate a  real effect on each treatment. Based on the results of the study it can be concluded that the  combustion  of horse manure organic fertilizer has the same real effect as organic manure of  chicken  manure and artificial compost on the growth of chilli plant height and has the same  effect    as organic fertilizer of chicken manure on the growth of the number of leaves. As for fruit  production, organic fertilizer horse manure has a real effect with all treatments.

Abstract

Tondok Bakaru Village in Mamasa Regency was designated as a Desa Sadar Wisata in 2019, as an effort to increase the local economy. The purpose of this study to determine the perceptions and motivations of stakeholders towards the development of Tondok Bakaru ecotourism. The phenomenological approach is used to analyze correlations between the proposed development with the economic development, ecology, and socio-culture. Study results are classified based on class intervals listed on the assessment graphs completed with associated descriptions. Notable findings here are as follows. Stakeholder's perception of Tondok Bakaru ecotourism development is on a ‘very agreeable’ scale. This is due to a ‘high desire’ scale expressed by stakeholders to have active roles in the development of ecotourism in Mamasa. Stakeholder motivation towards economic development is also on a ‘high scale’. Many stakeholders also express that it is necessary to improve tourism infrastructures, provide support for orchid cultivation-related business, development of networks for food provision, and other supporting facilities. Aspiration for the development of ecology-based tourism is also on a rather ‘high’ scale, as the concept of Tondok Bakaru ecotourism has not been well-conceived that indeed has disrupted the hydrological system, land conservation, and preservation of flora and fauna. Moreover, aspiration for socio-cultural development is on a ‘very high’ scale. This is influenced by a great concern on the gradual extinction of Tondok Bakaru Village’s socio-cultural assets.Keywords: ecology; economy; ecotourism; stakeholder; socio-culture AbstrakDesa Tondok Bakaru di Kabupaten Mamasa ditetapkan menjadi Desa Sadar Wisata pada tahun 2019 sebagai upaya peningkatan daya tahan ekonomi lokal. Tujuan penelitian ini adalah untuk mengetahui persepsi dan motivasi pemangku kepentingan terhadap pengembangan ekowisata Tondok Bakaru. Pendekatan fenomenologi digunakan untuk menganalisis persepsi dan motivasi terhadap pengembangan ekowisata yang berkaitan dengan ekonomi, ekologi dan sosial budaya di Tondok Bakaru. Hasil analisis dikelaskan berdasarkan interval kelas pada grafik penilaian dan pemaknaannya diuraikan secara deskriptif kualitatif. Persepsi terhadap pengembangan ekowisata Tondok Bakaru berada pada skala sangat setuju karena didasari oleh adanya keinginan yang tinggi dari pemangku kepentingan untuk berperan aktif pada pengembangan ekowisata di Kabupaten Mamasa. Motivasi pemangku kepentingan terhadap pengembangan ekonomi berada pada skala tinggi. Terbatasnya penunjang ekonomi ekowisata sehingga perlu dilakukan pembenahan infrastruktur, pengadaan inkubasi kelompok usaha budidaya tanaman anggrek, makanan dan penyewaan fasilitas penunjang. Motivasi pada pengembangan ekologi ekowisata pada skala agak tinggi karena konsep pengembangan ekowisata Tondok Bakaru belum tertata dengan baik yang memungkinkan terganggunya sistem hidrologi, konservasi lahan dan pelestarian flora fauna. Motivasi pada pengembangan sosial budaya berada pada skala sangat tinggi karena dipengaruhi oleh keprihatinan pada asset sosial budaya yang saat ini terancam punah.Kata kunci: ekologi, ekonomi; ekowisata; eemangku kepentingan; eosial budaya

Abstract

Community service programs are implemented to solve problems after corn is harvested, this problem is faced by partner groups. The dependence of partners on traders who provide loans in the form of agricultural production facilities, makes farmers' incomes low. The provision of multifunctional machine technology, socialization, demonstration, and training is expected to be able to overcome the problems. Data processing using the Likert Summated Rating Scale (LSRS) with numbers 1-5 from the very poor to very knowing category. The ability of farmers to use machines after harvesting corn is categorized as understanding. All members of the farmer group understand and are able to operate the corn sheller machine owned by the traders, but at the time of operating the multifunction machine only some farmers are able and understand the operation of the machine. Demonstrations involve partners in the preparation, operation and production of multifunctional machines. By the end of the machine demonstration, almost every farmer has understood the function of each machine. The knowledge of farmers about making animal feed from corn cobs has increased to very knowledgeable. With the existence of multifunctional machines, it is hoped that farmers will not depend on traders and can increase their income from their corn products. The profits that farmers get are expected to be used as capital to fulfill production inputs for corn cultivation. Machine technology brings changes in farmers' activities and social changes by changing lives from an economic perspective, making it easier for farmers to peel and break corn

Abstract

The need for built-up areas in the City of Makassar has continued to increase in recent years due to the rate of population growth. The reduced availability of land in the center of Makassar City causes the demand for built-up areas to shift to suburban areas. In this shift, there is a process of changing the use of non-built-up land into built-up areas. Reduced use of non-built-up land in suburban areas can cause environmental damage. The aims of this study are: (1) to predict changes in land use in Makassar City until 2034, (2) to develop directions for controlling built-up areas. The method used is visual interpretation (digitize onscreen) to obtain land use maps for 2012 and 2022, the Land Change Modeler (LCM) model to predict land use change in 2034 by comparing two land use scenarios, namely Without Scenario (TS) and Restriction Built-up Area (PAT). Scenarios that are able to reduce the rate of development of built-up areas will be chosen as directions for spatial use until 2034. The results of this study show the same pattern of land use change in the two scenarios used, namely only settlements, built-up land and open land that experience an increase in area during the analysis period. However, this scenario differs in terms of the extent of change. In the TS scenario, settlements increase by 706 ha (34%), built-up land by 272 ha (13%) and open land by 61 ha (3%). This increase reduced the area of paddy fields by 425 ha (20%), mixed gardens by 228 ha (11%), ponds by 222 ha (11%), shrubs by 69 ha (3%), forest by 52 ha (3%) and water bodies by 44 ha. (2%). Whereas in scenario 2, the increase in settlement area is only 265 ha (31%), 114 ha (13%) built-up land and 44 ha (5%) open land, so that the decrease in the area of other land uses is also small, namely rice fields 186 ha (22 %), ponds 109 ha (13%), mixed gardens 88 ha (10%), shrubs 21 ha (2%), ponds 12 ha (1%) and forest 7 ha (1%). The PAT scenario proved to be more effective in restraining the rate of development of built areas so that it was chosen as the direction for controlling built areas in Makassar City until 2034.

Abstract

Kota Sorong terletak dibawah garis khatulistiwa tepatnya pada koordinat 0º 54' 0'' LS dan 131º 51' 0'' BT yang memiliki tipe iklim A (sangat basah) dan termasuk dalam kategori daerah panas/tropis menurut system klasifikasi Scmidt-Ferguson, dimana tingkat erosi cenderung tinggi. Erosi adalah peristiwa terkikisnya atau hancurnya agregat-agregat tanah pada lapisal top soil sehingga terjadi transformasi bahkan translokasi dari partikel-partikel tanah. Potensi erosi pada suatu tanah dipengaruhi oleh erosivitas dan erodibiltas tanah. Maka dari itu dilakukan kegiatan pendampingan lapangan sebagai bentuk aktualisasi penerapan teori tentang pengaruh erosivitas dan erodibilitas terhadap potensi erosi yang terjadi, agar pemahaman peserta tentang potensi erosi dan korelasinya dengan intensitas dan curah hujan terhadap topografi dan tutupan lahan yang berbeda semakin meningkat serta mampu menganalisis dan menentukan kategori erosi yang terjadi. Pendampingan praktek lapang dilaksanakan pada tanggal 1 Juni 2021 di Gunung Dozer Malanu, Klagete Distrik Sorong Utara. Dari hasil pengamatan dilapangan diketahui bahwa pada tekstur tanah, struktur tanah, porositas dan infiltrasi yang sama namun berbeda topografi dan tutupan lahan maka berbeda tingkat erosinya. Dalam pelaksanaan kegiatan ini menunjukkan adanya capaian yang positif terbukti saat kegiatan berlangsung, peserta sangat antusias dalam pembagian tugas masing-masing anggota kelompok dalam praktek simulasi serta pada saat monitoring dan evaluasi yang dilakukan peserta aktif dalam memaparkan hasil pengamatan dan aktif dalam diskusi, sehingga ada umpan balik tentang bagaimana teknik konservasi tanah yang baik untuk dapat meminimalisir erosi.
